Water begets intricate and profound linkages between multiple systems. Quantitative limits to freshwater availability for human needs, variabilities in the water cycle and environmental water requirements interact with water source pollution. The arising tensions are a great challenge of immense contemporary significance that can best be described as a wickedproblem –a problem with multiple dimensions that presents unexpected consequences when engaged. Water challenges make vivid the compromises that must be made between the environment and development. These compromises surface in the conflict between ecocentric and technocentric discourse. Globally, there is evidence of numerous disciplinary and interdisciplinary water-related studies both in the past and ongoing. But there is no meta-mapping of various dimensions of such research to give a clear overview of what has been and what needs to be done. Consequences of this oversight may include unnecessary duplication of research, difficulty in articulating knowledge gaps and inability to see beyond disciplinary boundaries. The author suggests an outline of how these difficulties can be engaged. This is done through a wide-ranging literature review to identify a range of issues of focus, which issues are then themed into imperatives for water research. These imperatives are subsequently systematised using four normative descriptors: problem, drivers and mitigation measures. In combination, these descriptors articulate a spectrum of the key issues around water research. The key issues are mapped onto various academic disciplines and societal partners to outline a schema for positioning of water research. The proposed mapping can facilitate interdisciplinary and transdisciplinary (IDTD) research by allowing researchers to benefit from relevant existing bodies of knowledge while also making explicit knowledge gaps and opportunities for collaboration. By locating academic fields within different worldviews, the outlined schema reveals common ground beyond disciplinary confines around which IDTD research can be instigated.
Stakeholder Participation in Water Resource Management Drop of Lifeijtsrd
Water resources are threatened both nationally and globally due to anthropogenic activities. This puts at risk the realization of the United Nations’ Sustainable Development Goals. It is for this reason that sustainable water resource management forms part of the key global development concerns. The present study sought the participation of community as well as stakeholders in management in Kipkelion West Sub County within Kericho County in Kenya. Descriptive research design was used in this study. The study population comprised of households and water management agencies within Kipkelion West Sub County. About 394 households were randomly sampled for the study while purposive sampling technique was used in selecting 10 key informants for interviews. The study area was in Kipkelion West Sub County within Kericho County in Kenya. Household questionnaires and interview guides were used in the data collection. Although the use of water resources was found to be communal in nature, the management was left in the hands of the resource owners and water other water resources management stakeholders. The main stakeholders in the water resource management in the study area were found to be the County Government of Kericho, Water Resources Authority WRA and Kericho Water and Sanitation Company KEWASCO . These stakeholders were found to be working consultatively to manage the water resources in Kipkelion West Sub County.

Brownfield Sites as Catalysts for Sustainable Urban Regenerationand the Deman...IEREK Press
Almost two decades today, the topic of brownfields has extensively been researched in urban sociology, urban planning, and human geography, and numerous Western-Centric studies have linked the redevelopment of the abandoned, contaminated, vacant or derelict sites to sustainable urban regeneration and achieving smart cities and sustainability goals in general. Yet, until this day, the concept has received little academic and practical attention in Middle Eastern contexts. Western contexts on the other hand including Europe, UK and USA continue to offer unique perspectives on approaching brownfields in ways that reduce the alarming spatial cluttering and address socio-spatial disparities and spatial segregation in addition to achieving economic and environmental goals, and similar to the global scene, brownfield sites make a large portion of the post-industrial city of Amman, the capital of Jordan. However, with the lack of a systematic definition for the urban phenomenon objectives, methods to identifying potential brownfield sites and evaluating the prioritisation of their redevelopment that takes into consideration context particularities, and with the absence of participative approaches that include the local community in the decision-making regarding these spaces, city planners fail to include the increasingly growing number of brownfield site that proliferate their cities in the urban planning practice. Through the examination of literature discussions on objectives, approaches, classification systems, methodologies, assessment and evaluation tools for the support of design and prioritising decisions for brownfield regeneration indifferent contexts, and through looking at the numerous potential alternatives for brownfield sites regeneration these contexts highlight, this paper bids to emphasise the importance of developing context specific, localised tools tailored for the Middle Eastern case. Building on the above, this paper identifies five potential brownfield typologies in the context of Amman; (1)residual planning outcomes; (2) discontinued mines and quarries; (3) unfinished mega-projects; (4) contaminated and hazardous sites, and; (5) miscellaneous abandoned sites and buildings, and ends on the note that looking at the increasing demand to meeting smart growth and sustainability needs, these urban landscapes may function as catalysts for achieving comprehensive sustainable urban regeneration.

Revitalization Strategy for Historic Core of AhmedabadIEREK Press
In India, dense historic urban settlements were developed with the intention of provision of spaces for adequate engagement of the people. Public squares and streets became important places of interaction. ‘Historic core,’ especially had public spaces meant for various socioeconomic groups. Ahmedabad city is a blend of a harmonious past and a vivacious present. Number of historical and architecturally important buildings were built during Muslim and Moghul rules. One of the first built structures within the walled city is the Bhadra fort, a citadel founded by sultan Ahmed Shah in 1411 with a huge public square in front, developed for purpose of procession and gathering. This Bhadra precinct went through various layers of transformation in different eras and now have become vulnerable due to congestion and encroachment. Though, a need for intervention was felt to bring back the lost vitality of the Bhadra precinct, it was realized that a comprehensive approach would be the necessity. Conservation and sensitive development approach was taken to tackle this problem through pedestrianization of the Bhadra precinct, rerouting of traffic and restoration of Bhadra fort. Larger level traffic and parking issues were also considered be-yond the site. Alternative use of Bhadra fort as tourist information center was considered. Urban design guidelines were proposed for harmonious development in the surrounding area. This proposal was considered for funding under Jawaharlal Nehru National Urban Renewal Mission(JnNURM)and was implemented. Many issues were faced during implementation of Bhadra project due to contextualization of informal commercial, religious and other cultural activities. Political, social and administrative factors also played immense role in implementation of proposal. Now since Ahmedabad has achieved the status of World Heritage City through UNESCO certification further implementation of this project will be relatively easy due to envisaged strong political and administrative support.
Unlocking the Potentials of Urban Architecture in Enhancing theQuality of Urb...IEREK Press
Currently more than half of world population are living in cities, while world is witnessing a rapid urbanization process particularly in cities of the developing and emerging countries, where urban poverty areas (UPA) with low quality of urban life (QUL) and lack of the usual urban spaces are the most significant urban phenomena that characterized those cities. In such an urban context there is a need for an efficient tool that contributes positively to the enhancement of the QUL, meanwhile to provide the best use of the rare vacant lands. This study argues that urban architecture as a design field offers a distinctive approach to a special type of buildings made for an urban setting, thus it can enhance the QUL in UPA through community projects. The study is based on an analytical study of selected cases of community projects in UPA that represents examples of how urban architecture through its potentials has a positive impact on its urban context, notably through community projects that strongly linked to real community needs. The results showed that urban architecture as a design approach for community projects have multiple roles that boost the socio-economic daily life, as well it supports various environmental issues towards better QUL.
The Sinkhole Occurrence Risk Mitigation in Urban Areas for the Historic Salt ...IEREK Press
The present research focuses on the definition of a novel methodology for sinkhole risk assessment above shallow salt mines. The research were carried out on the area above the Wieliczka salt mine, a World Heritage site. The study of vertical stresses on the basis of a theoretical state of rock mass deformation in the area of test chambers was performed. Furthermore, the risk of chamber collapse due to ventricular stress exceeding the limit specified in the zone were calculated based on the arch pressure theory. The final stage of the research consists of spatial analysis that leading to the identification of chambers potentially influenced by other risk factors. The research shown in the article strongly suggests that combined spatial analysis with geotechnical analysis may lead to reliable sinkhole risk assessment methodology.
In Search of a Tool to Support Planning Inside Large Cities: the SustaIn-LED ...IEREK Press
The aim of the present study is to investigate the linkages between local economic development, innovation, and environmental sustainability inside urban areas. Can innovation affect the improvement of the quality of life inside urban areas? This research question comes from the consideration that usually innovation and growth in general are considered sources of conflict in affecting the livability of large cities. The objective of the paper is to design a model — the “SustaIn-Led” - to connect levels of environmental sustainability, quality of life, and economic development inside metropolitan areas, taking into account also innovation processes, activated by the innovation policies and by the knowledge economy. The study takes in consideration the 53 largest United States metropolitan areas with a population over 1 million, with a time series from the years 2000 through 2015.This has been done because of a two-fold reason: (1) the US among high-income countries is the one with the highest number of universities, patents, and citations; (2) several studies have shown that innovation occurs in large cities. The first part of the present study has carried out the identification of the variables to represent and significantly explain the phenomena – local economic development, innovation, and environmental sustainability – linked to the design of the SustaIn-LED model. Environmental sustainability in urban areas in this paper is represented by means of the Air Quality Index (AQI),while the number of workers synthetically quantifies local economic development. Correlation and multiple regression analyses are conducted in order to examine the relationship between the three main indicators. The multiple regressions for the year 2015 produced a low p-value, indicating that the predictors are significant in the regression analysis. Similar results of p-value are shown in all the years from 2000 to 2013. For 2015, the results showed that part of the variance in the measure of total workers of the metropolitan areas could be predicted by measures of innovation and air quality. Higher R2values have been registered for the years from 2000 through2013.The development of the SustaIn-LED model could be utilized in urban regeneration processes to help in the design of new urban planning policies inside large cities by means of a better comprehension of environmental and economic implications caused by the implementation of innovation policies.
Estimation of Coating Materials Contribution to the TVOCsEmissions of Wood Fl...IEREK Press
Based on the increasing concern about the exposure to volatile organic compounds (VOCs) from indoor finishing materials, industrial companies are called to meet the growing demand for more sustainable products. Recently, most designers and consumers have more environmental considerations while selecting the finishing materials. These considerations are related to the VOCs content of the finishing material itself regardless of its coating layers. Nowadays, interior wood coatings are commonly applied to large surfaces (ceilings, walls, floors) and many types of furnishing, leading to a high loading factor (surface-to-volume ratio). These coatings might contribute significantly to the VOCs emissions due to repeatedly and periodically use during maintenance, remodeling, and renovation of interior spaces. The aim of this study is to estimate the wood coating materials contribution to the TVOCs emissions of wood product in the indoor environment to shed light on the importance of comprehensive analysis of wood material with all treatment coatings. So, a small interior space with controlled temperature, relative humidity, and air exchange rate was simulated using IA-Quest program to investigate the influence of three wood coating materials; stain, wax, and varnish which were applied to an area of natural hardwood Oak floor. The TVOCs emission data resulted from the different coated wood floor was compared with VOCs emissions caused by the natural wood floor to find out the coating material contribution in TVOCs emissions of a wood flooring material
Sustainable Park Landscaping as an Approach for theDevelopment of the Built E...IEREK Press
Implementing sustainable principles when landscaping parks is vital for the development of the built environment, and should take into account environmental, social, economic, and cultural aspects, in order to eliminate conflict between developmental requirements, and the need to preserve cultural and natural resources. This paper reviews the guidelines that should be considered for current and future sustainable parks in regions with a moderate climate, in order to ensure that they incorporate ecotourism, cost effective operation and maintenance, a clean environment, the promotion of renewable energy, and resource preservation. A number of parks, located in moderate climate zones, are studied in terms of aspects such as their location, topography, operation, and landscaping characteristics, to demonstrate the prevailing normative values that can be applied to sustainable park design. Prince Meshari Park, in Al-Baha city, Saudi Arabia, is employed as a case study for applying all of the guidelines proposed in this investigation, and to highlight some of their merits and limitations in terms of the current situation of the park.
Load Shifting Assessment of Residential Heat Pump System in JapanIEREK Press
With the economic growth and increasing requirement of indoor thermal comfort, the load of building sector presents a greater variability. This paper aims at analyzing the energy consumption characteristics and influencing factors of the residential heat pump system. Firstly, we selected residential households as investigated objective in Kitakyushu, Japan, and compared the energy saving performances of heat supply systems between heat pump and natural gas boiler. The results were based on real measured residential load during winter period, and calculated the cost saving performance of residential heat pump system compared with traditional natural gas boiler. We also did a survey of residential occupation behavior for the 12 selected residential customers. The result indicated that there was low relationship between power consumption and occupation hours, and the number of family members had a significant impact on the power consumption. The results indicate that residential heat pump system presented promising energy saving and cost reduction potential
A Model Proposed for the Prediction of Future Sustainable Residence Specifica...IEREK Press
In Egypt, people are unable to determine the qualities of appropriate residence that achieves quality and occupant satisfaction, and contributes to sustainability of residential conglomerations. In general, developing countries lack housing information which can be used to enhance quality of residence. Also, the methods of assessing and identifying the appropriate criteria for future residence quality remain traditional ones that cannot address the multiple, conflicting, overlapping aspects to reach a good decision. This calls for using the Analytical Network Process (ANP), an effective tool for specifying the relative importance of all factors impacting a specific issue for making an appropriate residential decision. In addition, this method provides results for the decision element impacts network within the decision structure; thus contributing to more understanding of the mechanisms and requirements of residence selection. The proposed decision structure comprises a two-level network: main clusters, main elements, and sub-elements included in the demographic characteristics group, the residence criteria group, the demand parameters group, the supply parameters group, the residence specifications group, and the alternatives group which representing, in total, the decision and specifying the percentage needed for each housing level. Results of the model showed complete capacity in smoothly addressing complexities and overlapping in the decision structure. The decision structure showed that 52% chose luxury residence, 28% chose middle-class residence, and 19.5% chose the economic residence. Mechanisms of decision making were analyzed; particularly in terms of relationship to demographic characteristics and residence specifications. Also, the importance and impact of demand / supply parameters in reaching decision were analyzed
Development of an Open-Source Water Consumption Meter for HousingIEREK Press
This article reports on the project "Design and development of water and gas P.L. measurement devices in the housing: an approach to sustainable consumption in Mexico", prepared at the Metropolitan Autonomous University in the Department of the Environment, whose objective was to develop a device to measure water consumption in the housing, which allows users to know their spending and can make decisions in favor of efficiency through the reduction of water use in household activities. The meter is made up of open source, programmable or reconfigurable software, which receives the signal from a water flow sensor and a casing designed to contain the hardware and facilitate the user's installation. Both the hardware and the casing can be purchased, downloaded, manufactured and assembled at home (Do It Yourself). As specific results were obtained: hardware programming and housing design and as a final result: the assembly of the functional prototype with which measurements of water consumption were made in a housing in Mexico. With this work we conclude that through the development of new accessible and common measurement technologies for the users of a house, it will be possible to promote efficiency in the use of natural resources in cities, increasing availability and promoting a more sustainable urban development.
Multi-Scale Assessment of Urban Gardens as Constructed Habitats for Biodivers...IEREK Press
Biodiversity in arid urban environments depends upon habitat formation that balances both bioclimatic and biophysical environment needs. There is the potential for urban gardens to establish symbiotic ecosystem services from microhabitat formation that collectively form an assemblage of ecological patches to connect a diverse range of flora and fauna, and establish community driven nursery and seed collection initiatives. This study of urban garden habitats situated within a new urban district of Jeddah Saudi. The analysis concentrates on the ability of garden spatial formations to construct a heterogeneous spatial morphology of sub-patch within the larger urban landscape patch. Patch and subpatch formations are examined based on the criteria of (I) assemblage of the spatial habitat (characterized by shape and spatial organization); (II) integration of spatial, functional and vegetation plantation patterns; (III) connectivity. Findings reveal that garden layout is structured by the integration and layering of plant types to generate cool understory habitat with seedling establishment, and water conservation. Designed layout of the garden as a spatial pattern is augmented with a range of microclimate mediators to dim solar exposure within the plantation habitat. A strong heterogeneity in plant formations and combinations is seen to dominant the garden formations.
Architectural Education for Sustainable Urban RegenerationIEREK Press
Urban regeneration is one of the important agendas of Turkey as a developing country. Rapid urbanization problems have been causing vital social and economic problems together with physical and spatial ones especially in big cities of Turkey. Thus, national and local governments handled urban regeneration as a practical method for solution of these problems. However, they unfortunately don’t implement urban regeneration according to its real requirements. Instead, this multi-dimensional and complex process is seen as a pull down and built up operation. Considering this situation and being in awareness of the responsibilities of architects throughout urban regeneration process, the authors think that urban regeneration should be discussed in the scope of architectural education. This paper presents the purpose, the process and the products of an undergraduate architectural design studio that was undertaken at Bursa Uludağ University, Faculty of Architecture. The architectural and urban design projects of the students of which aim was to offer a livable and sustainable mixed used living environments are discussed together with their conceptual backgrounds. Putting stress on the differences between theory and practice, the conclusion introduces a critical evaluation of urban regeneration and sustainable housing concepts in Turkey.
Typology and Solar Gain Analysis: Vernacular Courtyard Houses of Tabriz, IranIEREK Press
The study presents the results of typological analysis and simulation modeling analysis of traditional courtyard residential houses in the cold semi-arid climate of Iran. The purpose of the research has been to analyze and evaluate traditional passive environmental strategies and their elements to provide implications for the design of sustainable residential buildings in contemporary time. Five existing traditional courtyard houses in the city of Tabriz, Iran, are used as case-studies to analyze the typology and the solar zoning conditions and to develop simulation models. The Ecotect simulation program is used to calculate the solar gains of the buildings and to analyze the effectiveness of the natural passive systems along with native design strategies in terms of potential solar gains of main and secondary living spaces. However, in the vernacular, not only the awareness of the climatic and topological considerations is important, but also the values, rituals, and beliefs that shape the design of the dwellings need to be considered. The research is based on the hypothesis that vernacular buildings (courtyard houses) of Iran have been environmentally sustainable structures. However, an important challenge of the study has been to avoid the technological bias and to consider the cultural and social aspects and embodiment of the studied houses, as well. The study also addresses the potential short comings that limit the reliability of Iranian vernacular architecture at present in order to arrive at a more holistic understanding of the sustainability of the vernacular architecture in the country.

According to the Energy Performance of Buildings Directive (EPBD), new buildings constructed within the European Union (EU) countries are expected to be nearly zero energy buildings (nZEBs) by 2020, while new public buildings are expected to adhere to this target by 2018. The Passivhaus approach has been identified by several researchers as a possible roadmap to achieve nZEBs. The meticulous engineering and high standards of the Passivhaus building fabric, in addition to the high comfort levels, are the main reasons behind the success and widespread of the standard. Recently, in 2013 the Passivhaus principles have been applied to an experimental residential project in the hot and arid climate of Qatar. The project is composed of two identical buildings, one built according to the Passivhaus standard and the other according to normal practices in the country. The thermal performance and comfort levels of both buildings were assessed through dynamic simulation and on-site measurements. Results indicated that at least 50% reduction in annual operational energy, water consumption, and CO2 emissions were achieved in the Passivhaus model in comparison to the standard model. This paper aims to highlight the lessons learned through the Passivhaus project; first by exhibiting the Passivhaus criteria that have been met, second by showcasing the outcomes of the project, and third by displaying the barriers and difficulties that have been associated with building according to the standard in Qatar. Finally, recommendations and general guidelines are suggested towards a possible adoption of the Passivhaus standard in Qatar and the Gulf Cooperation Council (GCC) countries
Optimal Sizing and Design of Isolated Micro-Grid systemsIEREK Press
Micro-grid and standalone schemes are emerging as a viable mixed source of electricity due to interconnected costly central power plants and associated faults as well as brownouts and blackouts in additions to costly fuels. Micro-Grid (MG) is gaining very importance to avoid or decrease these problems. The objective of this paper is to design an optimal sizing and energy management scheme of an isolated MG. The MG is suggested to supply load located in El-shorouk Academy, Egypt between 30.119 latitudes and 31.605 longitudes. The components of the MG are selected and designed for achieving minimum Total Investment Cost (TIC) with CO2 emissions limitations. This is accomplished by a search and optimization MATLAB code used with Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) techniques. The use of Diesel Generators (DGs) is minimized by limiting the gaseous CO2 emissions as per targeted allowable amount. A comparison is accomplished for investigating the CO2 emissions constraints effects on the TIC in $/year and annual cost of energy in $/kWh. The obtained results verified and demonstrated that the designed MG configuration scheme is able to feed the energy entailed by the suggested load cost effectively and environmental friendly.
Regenerative Mobility: Disruption and Urban EvolutionIEREK Press
Mobility plays an important role in the cities by enabling people to carry out the most varied activities across the territory, as well as to ensure the city fully function. In addition, analogies to the human organism can be made by this urban dynamic, looking for solutions to specific issues. Moreover, this paper has been based by the premise that phenomena and urban elements could be conceptualized, explained and transformed from contemporary and innovative approaches applied in the medical field. For this reason, this paper aims to develop and present a new concept associated with urban mobility, based on the principles of regenerative medicine: the Regenerative Mobility, a concept with disruptive and evolutionary purposes. Furthermore, the structure of this paper is summarized by the introduction which contextualizes the theme, presents and characterizes the techniques used in the research. Additionally, the following chapters explore essential aspects of the city, explaining why it needs a mobility change and new concepts. Therefore, the concept of Regenerative Mobility is presented as a potential of mobility and cities improvement, followed by pragmatic cases, capable of illustrating some of its principles.
Unlocking the Potentials of Urban Architecture in Enhancing the Quality of Ur...IEREK Press
Currently more than half of world population are living in cities, while world is witnessing a rapid urbanization process particularly in cities of the developing and emerging countries, where urban poverty areas (UPA) with low quality of urban life (QUL) and lack of the usual urban spaces are the most significant urban phenomena that characterized those cities. In such an urban context there is a need for an efficient tool that contributes positively to the enhancement of the QUL, meanwhile to provide the best use of the rare vacant lands. This study argues that urban architecture as a design field offers a distinctive approach to a special type of buildings made for an urban setting, thus it can enhance the QUL in UPA through community projects. The study is based on an analytical study of selected cases of community projects in UPA that represents examples of how urban architecture through its potentials has a positive impact on its urban context, notably through community projects that strongly linked to real community needs. The results showed that urban architecture as a design approach for community projects have multiple roles that boost the socio-economic daily life, as well it supports various environmental issues towards better QUL.
Urban Public Space Axis Rector of Green Infrastructure in the Current City of...IEREK Press
The current city calls for the reconsideration of a close relationship between gray infrastructure and public spaces, understanding the infrastructure as a set of items, equipment, or services required for the functioning of a country, a City. Ambato, Ecuador, is a current intermediate city, has less than 1% of the urban surface with use of public green spaces, which represents a figure below the 9m2/ hab., recommended by OMS. The aim of this paper was to identify urban public spaces that switches of green infrastructure in the city today, applying a methodology of qualitative studies. With an exploratory descriptive level analysis, in three stages, stage of theoretical foundation product of a review of the existing literature, which is the theoretical support of the relationship gray infrastructure public spaces equal to green infrastructure. Subsequent to this case study, discussed with criteria aimed at green infrastructure and in the public spaces of the study area. Finally, after processing and analysis of the results, we provide conclusions for urban public space as a definition of the green infrastructure of the current city of Latin America; in the latter, the focus is to support this article.

is generally out of the realm of control of humans and is not included in water scarcity studies. The remaining 40%
is renewable water which is framed in reference to the global demands of two categories: (i) anthropogenic water
requirements (ii) environmental water requirements (Rijsberman, 2006; Smakhtin et al, 2004). Due to its cyclic
nature, water supply and sanitation cannot be delinked.
Water occurs in a continuous hydrological cycle that entangles humans with biotic and abiotic systems in multiple
pathways. Water’s cyclic occurrence and omnipresence, coupled with its indispensability for the survival of humans
and ecosystems, defines myriads of systems with mutual feedback loops. Securing freshwater for growing populations
is a grand challenge in the Anthropocene. Rijsberman argues that water is critical to an array of global challenges
from health, to malnutrition, poverty, and sustainable natural resources management (2006). Today, this complex
challenge is articulated as the water-energy-food-health nexus (Amorim et al, 2018; International Water Management
Institute, 2019). It can therefore be argued that the water challenge is a wicked problem. A wicked problem is one
which eludes precise definition, whose amelioration demands uncomfortable compromises, and for which
intervention in one realm yields unexpected results elsewhere (Webber and Rittel, 1973).
Water-focused research spans ecology, social-sciences, engineering and many more disciplines. Freshwater research
is wide in scope and has yielded numerous disciplinary and interdisciplinary studies. Publications have covered such
topics as water availability, scarcity and response to scarcity (Falkenmark et al, 1989; Guppy and Anderson, 2017;
World Economic Forum [WEF], 2019) 2019; Shiklomanov, 1991; Kuylenstierna et al, 1998); aquatic ecosystem
system services (Abell et al, 2019; Vörösmarty et al, 2018; Costanza et al, 2014); water and climate change
(Vörösmarty et al, 2000 and Arnel, 1999); wastewater and pollution (Connor et al, 2017; World Health Organization
[WHO], 2004; Karr and Dudley, 1981); and the relatively new field of water sensitive design (O'Farrell et al, 2019;
Sharma et al., 018; Howe and Mitchell, 2011; Wong and Brown, 2009; Carden et al. 2018). Water research also
extends to issues of rights and water, social justice, law and discourse analysis.
Together, these fields outline an impressive spectrum of water-related research. However, critical evaluation of
literature reveals that none of these publications provides a strategic overview of water research because they speak
to diverse, if overlapping, research fields. The result is that water-related research, though impressive in scope and
depth, has not yet, to this author’s knowledge, been systematised to relate its diverse fields and subfields. This paper
attempts to derive a comprehensive yet non-prescriptive outline to cover the breadth and scope of water-related
research. Such an outline can make possible reflexive contextualisation of past, present and future research to
facilitate collaborative synergies, identify knowledge gaps, and pre-empt duplication in water-related research. Thus,
this paper is aimed at enabling researchers to critically position past and ongoing water research AND to surface
collaboration possibilities in future disciplinary, interdisciplinary and transdisciplinary research endeavours.
2. Method
This paper uses systematic literature review to uncover and characterise different aspects of water-related research.
The literature reviewed includes articles in peer-reviewed academic journals, some books and publications from
multilateral organisations. Endnote is used as a software to organise and theme the literature.
After Beker (2003), the paper adapts a three part approach to the literature review to cover analytical, normative and
operational level literature. Analytical level literature focuses on worldviews. Normative literature covers definitions,
goals, criteria and indicators. And operational literature proposes particular strategies and actions to deal with specific
problem situations.
First, normative and operational level literature is analysed. Referencing the postulate that problems are “the
fountainhead” of research (Becker, 2006), the paper takes water-related disutilities to society and the environment as
a starting point. These disutilises are captured in a set of problems: societal water scarcity; environmental water
scarcity; temporal variations in the water cycle (drought and flooding); and water pollution. Each problem is discussed
in turn.
Normative and operational level water literature results in a three-part systematisation: problems, causes and
mitigation measures. This becomes the vertical dimension of the outline schema for water related research.
3. Sanya/ Environmental Science and Sustainable Development
pg. 50
Apart from the water-related problems, there is emergent discourse which problematises the dominant quantitative
water discourse. This is covered separately as part of normative and operational level literature.
The next part of the paper is at the analytical level. It focuses on a higher level framing of the normative and
operational literature. This part specifically draws from O’riordan (1981), Drysek (2013), Groat and Wang (2002)
and Naess (1990 and 1973) to situate normative and operational literature within different worldviews.
The final part references a classification of different academic fields and locates them within different worldviews.
The worldviews together with the academic fields become the horizontal dimension in the outlined schema for water
research.
Mapping the vertical and horizontal dimensions together outlines a schema for systemisation of water related research.
3. Water Research Literature
3.1. Societal Water Scarcity
Globally, humans abstract over 4 000 Km3
(4000 billion m3
) of available freshwater annually. 12 percent of abstracted
freshwater is municipal water for domestic and commercial purposes (Food and Agricultural Organisation [FAO],
2016) such as drinking, food preparation, personal hygiene and sanitation and watering of ornamental landscapes.
Domestic water scarcity is evidenced by the 844 million people worldwide who lack access to safe water and the 2.4
billion people without access to improved sanitation (United Nations International Children Education Fund
[UNICEF] and World Health Organisation [WHO], 2015). Domestic water scarcity, which occurs mostly in poverty
stricken rural areas and urban informal settlements (Center for Disease Control and Prevention [CDC], 2015; Hou et
al, 2014), significantly reduces wellbeing and is associated with a range of health risks. Contaminated water and poor
sanitation are linked to transmission of diseases such as cholera, diarrhoea, dysentery, hepatitis A, typhoid, and polio
(WHO, 2019b). More than 820 000 people die each year from diarrhoea as a result of unsafe drinking-water, poor
sanitation, and due to poor hygiene (WHO, 2019b; UNICEF and WHO, 2015). The majority of the world’s population
is already urbanised and, driven by population growth and migration from rural areas. The rate of urbanisation is
accelerating – particularly in the resource challenged Global South (United Nations, Department of Economic and
Social Affairs Population Division, 2019a and 2019b). Therefore, inadequate water and poor sanitation will continue
to be a significant challenge. This challenge is proactively acknowledged in Sustainable development Goal 6 (Clean
Water and Sanitation) (United Nations, 2017). The research imperative that emerges here is secure safe water and
sanitation for those who lack access.
At 69 percent, the largest freshwater consumer is agriculture (irrigation, livestock and aquaculture) (FAO, 2016).
Global projections are that, due to growing population, agricultural water demand will continue to grow (Conforti,
2011). Seventy times more food will be needed by 2050 (Conforti, 2011). About 20 percent of freshwater abstracted
by humans is used for industrial purposes and energy production (FAO, 2016). Taken together agricultural and
industrial water use is expressed in GDP/m3
of water. That is, like embodied energy, every product contains “virtual
water” (Hoekstra, 2003; Chapagain and Hoekstra, 2004). Generally, as populations grow and standards of living
increase, water use increases proportionately (Conforti, 2011). However, others have argued that an efficiency
revolution, similar to the energy revolution is possible. Indeed, recent evidence suggests that there is not necessarily
a linear mapping of population growth and standards of living with water consumption (Gleick, 2003). That is,
increase of water productivity is possible (Gleick, 2003). Research into increasing water productivity is paramount.
Often, water for human use is scarce despite its abundance in natural systems – a phenomenon known as economic
water scarcity (Rijsberman, 2006). At a macro-level, economic water scarcity is caused by lack of capacity in terms
of capital, technology and infrastructure to deliver the water for human consumption. At a micro-level economic
water scarcity is faced by poor households that cannot afford to be connected to infrastructure e.g. in informal
settlements. Poverty and water scarcity, coupled with malnutrition and ill health, result in a vicious poverty-water-
food-health nexus that poses a critical global challenge (Amorim et al, 2018; Weitz et al, 2014). Clearly, SDG 6 (clean
water and sanitation) is key to achievement of many other SDGs, such as: no poverty, zero hunger, good health and
well-being, reduced inequalities, sustainable cities and communities, life below water, and life on land. Economic
4. Sanya/ Environmental Science and Sustainable Development
pg. 51
water scarcity may also be due to governance failure whereby poor institutions, institutional fragmentation, and lack
of transparency and accountability result in societal water scarcity despite its abundance in natural systems
(Akhmouch and Clavreul, 2016). Research imperatives emerging here are about: securing clean water and sanitation
for vulnerable populations and households.
The above biophysical characterisation of water scarcity is extended by critical perspectives that position water
availability in rights and social justice. Arguing that water cannot be substituted, Shiva (2006) posits that water must
be free for all people and the environment. She argues that access to water is not a favour but a right. Mehta (2003)
highlights the variability of the water cycle across space and time to argue that the idea of enduring drought and
permanent water scarcity is without basis. She contends that scarcity is essentially transient but modernity made it
permanent. She argues that water scarcity is always interspersed with overabundance and that water availability is
regularly irregular. She adds that vested powerful interests promote an alarmist narrative of water scarcity to obfuscate
asymmetries in water access. In a granulated analysis, Metha draws attention to the distributional and relational
aspects of scarcity to argue that scarcity is not felt universally by all. This for example is when powerful agricultural
and industrial interests and rich elites consume huge quantities of underground water resulting in depletion of poor
people’s wells. And large technical solutions such as dams and canals are designed to maximise allocation of scarce
water to the powerful agro-industrial interests at the expense of the marginalised poor. In this way, argues Mehta
(2003 and 2001), the rich are water secure but cause scarcity in poorer communities
Shiva (2006) highlights the Plachimada Declaration on water democracy as a victory of community movements
against big private interests. The declaration asserts that because water is not a human invention and cannot be bound,
it should not be sold as a commodity. Water cannot be substituted and all people and the environment have a right to
sufficient water. The Plachimada Declaration is elevated to a symbol of struggle for water rights (Shiva, 2006).
3.2. Environmental Water Scarcity
On the other hand, abundance of water in human systems does not necessarily imply absence of water scarcity.
Ecological systems have environmental water requirements (EWR) (Smakhtin et al. 2004; Rijsberman, 2006). The
Falkenmark indicator (water stress index) is a combined metric for human and environmental water requirements
(Falkenmark et al, 1989). When available renewable water per capita per annum is less than 1700m3, the country is
defined as experiencing water stress. Water scarcity occurs at less than 1000m3 renewable water per capita. Absolute
water scarcity occurs at below 500m3 renewable water per capita per annum. There is also a variety of other measures
of water scarcity (Rijsberman, 2006). And, according to the United Nations (2015), 1.7 billion people are currently
living in river basins where water use exceeds recharge. Depleting lakes and aquifers and rivers drying up before they
reach the sea are obvious signs of unsustainable abstraction and environmental water scarcity. The Colorado River in
the United States and the Yellow River in North China, are frequently completely or partially depleted before they
reach the sea every year . The Aral Sea and Lake Chad are examples of water bodies disappearing because of reduced
river inflows (see Mekonnen and Hoekstra, 2016). A key research imperative therefore is to measure anthropogenic
and environmental water scarcity using the Falkenmark Index or another suitable indicator. Smakhtin proposes that
environmental water requirements (ERW) be determined by classifying ecosystems into four classes: 1. Natural
(pristine and unmodified); 2. Good (slightly modified); 3. Fair (moderately disturbed); 4. Poor (critically modified
and degraded). Smakhtin recommends environmental water allocation for each ecosystem whereby the more
undisturbed the system, the more water environmental water should be allocated to it to keep it in that condition
(Smakhtin et al. 2004). A key research imperative is therefore setting environmental management and water
allocation objectives by classifying ecosystems.
Environmental water is essential for ecosystem health and protection of freshwater ecosystem services. Freshwater
ecosystems provide a range of valuable goods and services such as flood protection, fisheries, recreation opportunities
and wildlife sanctuaries (Revenga et al, 2000; Acreman, 2001, Vié et al, 2009). It is estimated that these services are
worth trillions of US dollars annually (Posteland Carperter, 1997). It is argued that freshwater ecosystem degradation
has resulted in loss of services valued at 20 trillion dollars annually (Costanza et al, 2014). It is therefore in society’s
interests that aquatic ecosystem water requirements are met. This means that in regional planning, ensuring sufficient
environmental water availability for watersheds is imperative.
5. Sanya/ Environmental Science and Sustainable Development
pg. 52
Most urban areas are fully built up or paved and would hence fall under what Smakhtin (2004) describes as “modified
beyond rehabilitation to anything approaching a natural condition”. Many cities do not have healthy freshwater
ecosystems – meaning that they forfeit the immense value of related natural goods and services. However, at the
intersection between nature and the urban built environment is ecological infrastructure, which is commonly
encompassed under Water Sensitive Design (WSD) (Donofrio et al, 2009). Water sensitive approaches to urban
design and planning can be used to introduce, safeguard and enhance freshwater ecosystems in the city. This is
through linking new and existing water bodies and greenery into networks of blue-green natural infrastructure (Wong
and Eadie, 2000; Carden et al, 2018; O'Farrell et al, 2019). Natural infrastructure offers active recreation opportunities
such as walking, jogging, cycling, canoeing and fishing. Blue-green infrastructure in cities is also known to mitigate
the urban heat island effect (Brears, 2018). Reduced temperatures, opportunities for active recreation and the
pollution-cleansing effects of nature result in overall health benefits for city residents (Coutts et al, 2013). Research
into WSD for protection and enhancement of urban freshwater ecosystems is imperative.
3.3. Temporal Variations in the Water Cycle
Water scarcity is complicated by the spatial and temporal variations in water availability due to the dynamic nature
of the hydrological cycle. The same place can experience scarcity and flooding in the same year. Global warming is
increasing the intensity, frequency and duration of extreme weather events (Cisneros et al, 2014 and Arnell, 1999).
The dynamic nature of the water cycle may explain why some authors argue that, unlike biospherical integrity and
land systems, freshwater availability is not a critical contemporary limit (Rockström et al, 2009). Yet, Mekonnen and
Hoestra (2016), in a fine scale spatial and temporal resolution, estimated that 66 percent of the global population lives
under conditions of severe water scarcity for at least one month of the year. Moreover, 40 percent of the world’s
population will be living in seriously water-stressed areas by 2035 (Guppy and Anderson, 2017 and Addams et al,
2009). In absolute terms, there has been a 55 percent drop globally in available freshwater per capita (Guppy and
Anderson, 2017) while by 2030, global demand for water is expected to grow by 50 percent (United Nations
Educational Scientific and Cultural Organisation [UNESCO], 2012). The World Economic Forum (WEF) warns that
water scarcity is amongst the top ten global risks in terms of likelihood and impact (WEF, 2019). The relatively
affluent are apparently oblivious to this critical problem given that they waste up to 80 percent of potable water on
uses for which non-potable water would suffice (Sisolak and Spataro, 2011). Globally, 30 percent of global water
abstraction is wasted through leakage (Liemberger and Wyatt, 2019). The reality of water-stress was emphasised, to
rich and poor alike, when Cape Town almost ran out of water in 2017 and 2018 in what was known in global popular
press parlance as Day Zero (Taing et al, 2019; Wolski, 2018). Thus, for significant portions of global population,
water stress is a new normal. This means that it is imperative for research to be focussed on adaption and building
resilience in the face of episodic and enduring water challenges. Adaptation and resilience building include:
diversifying supply; reducing leakage; mainstreaming fit-for-purpose water use to avoid wastage of potable water;
developing efficient technologies to reduce water consumption and wastage; nudging consumer mindsets from water
wasteful to water mindful; and increasing water productivity. Furthermore, civilisations have been known to flourish
in historically water stressed geographies because they developed adequate institutions (Rijsberman, 2006). Mehta
(2003) also demonstrates that local people have evolved flexible livelihoods in order to intermittent availability of
water. Hence, building resilience requires developing appropriate institutions for water governance.
But it is not just water scarcity that is at issue. Due to the dynamic nature of the water cycle, extreme weather events
can cause sudden water overabundance which can result in flooding and landslides. Water plays a major role in all
disasters. 90 percent of all disasters in 2017 were water related (Centre for Research on the Epidemiology of Disasters
[CRED] 2017). Floods and landslides alone accounted for more 75 percent of the disaster-related deaths (ibid).
Climate change has been foregrounded as a cause of water scarcity. Due to climate change, the occurrence and
severity of extreme weather events is projected to increase (WEF, 2019). Hence, adaptation to and mitigation of
flooding is another important research imperative. Mehta (2006) claims that the attribution of long droughts to climate
change is not supported by local data and instead, more attention should be focused on human-induced scarcity due
to deforestation and unsustainable irrigation, for example. Edwards (2013) argues that, in Australia, the narrative of
an imminent water crisis induced by climate change is accompanied by neoliberalization of water governance.
6. Sanya/ Environmental Science and Sustainable Development
pg. 53
Bringing water to one area leaves a deficit elsewhere (Shiva, 2001). Dams upstream create scarcity downstream
(Hussien, 2017a). Dams to provide water and power flood nature, displace communities and cause massive loss of
flora and fauna.
Water can be a political matter. According to Yorke (2016), in water scarce countries such as Jordan, water is an
instrument of patronage and power. And powerful elites consistently ignore or frustrate water demand management
aimed at securing sustainable yields. Therefore, water demand and supply is not just one of demand and supply but
it is also a wider structural problem of national governance. For this reason, Hussien (2018) argues, engineering and
geological perspectives on water scarcity must be complemented by insights from the political and social sciences.
3.4. Water Quality and Pollution
Most water consumed and used by humans becomes part of the environment and the water cycle again. This opens
numerous pathways for pollution. Two billion people worldwide contaminate water with faecal matter (WHO, 2015).
Globally, 80 percent wastewater is dumped untreated (UN Environment). In developing countries, 70 percent
industrial waste is untreated. 15 – 18 billion m3 of freshwater resources are polluted by fossil fuel production annually
(UNESCO, 2020).
Eutrophication - from wastewater and agricultural run-off - has, according to recent estimates, reduced biodiversity
in rivers, lakes and wetlands by about one-third globally. Ironically, eutrophication and biochemical oxygen demand
(BOD) are caused by depletion of valuable nutrients and organics from society (Sisolak and Spataro, 2011). Hence,
harvesting nutrients and organics from wastewater before releasing it to the environment simultaneously protects the
environment and reclaims resources for agricultural systems. Two imperatives emerge here (1) to research pollution
of freshwater systems (2) research circular economy systems for wastewater treatment and resource reclamation.
3.5. The Vertical Dimension
The above literature review reveals water related discourse from different perspectives. To find a common thread in
the different perspectives, the literature-derived research imperatives are systemised into three distinct but interrelated
categories:
− Problem description
− Problem drivers
− Mitigation measures
The first category is analysing and describing existing problems in reference to human and environmental systems.
This category addresses the scale and scope of problems around water quantity and quality. One of the problems is
water scarcity as measured against human and environmental water requirements. Another problem is the episodic
occurrence of overwhelming amounts of water characterised as flooding. It is also here that the increasingly chronic
nature of global water stress and the uncertainties unleashed by climate change are covered. A final problem is around
water pollution and its effects. Therefore, research focus here is to describe the problem in terms of water quantity
(scarcity, flooding and climate change) and water quality (pollution) over a range of spatial and temporal scales
[descriptive research].
In the second category, the drivers of each of the problems above are analysed. The focus is to analyse the drivers of
these problems [analytical research].
A final category is related to mitigation measures focused on addressing each problem. This includes setting
performance targets (normative guidelines) using expert-led and/or participatory processes. It also focuses on
generating new solutions or applying existing ones in a different context. This category also covers evaluating past
solutions for positive and negative lessons [normative, creative, applied and evaluative research].
The problems, their drivers and associated mitigation measures form a broad spectrum of agendas for water research
and constitute the vertical dimension in this paper’s high-level outline.
7. Sanya/ Environmental Science and Sustainable Development
pg. 54
3.6. Water Discourse
Apart from the literature about water, its availability and distribution, there is specific literature that focuses on
discourse analysis of water-related research. The same reality can generate different, even opposed, discourses
(Hussien, 2017a). In the extreme, some others claim that the environment is socially constructed (Escobar, 1996: 46).
For Hussein (2017b), discourses do not just help us to make meaningful stories but constitute a substantial reality
imbued with actual agency. Discourses define what matters and they foreground some issues and solutions at the
expense of others. Dominant discourses are deployed across generations through textbooks at the interfaces of formal,
practical and popular geopolitics (Ide, 2016). For Pieterse (1992) participation brings integration, rather than
emancipation. Participation is problematised as being asymmetrical and manipulative (Mehta, 2006).
Power converges through coalitions of actors sharing the same discourse but not necessarily the same motives.
Discourses connect local and international arenas to generate huge networks of actors from academic and non-
academic spheres. Big infrastructure projects engender conflicting discourse alliances as described by Hussien
(2017a) for example. Discourses and the coalitions they create are alive and mutable. Actors, discourses, plans and
motives evolve with changes in broader contextual factors. Because of the contested context, Hussien (2017b)
suggests that water discourses ought to be extended from the watersheds to the “problemsheds” beyond.
4. Worldviews
This section uses worldviews to reflect, at higher level, on the above normative and operational literature. Groat and
Wang (2002) identify three worldviews. The positivist worldview underpins rational science and its quantitative
approaches. It aims for value-free research as an ideal. The naturalist paradigm embraces multiple, socially
constructed realities and the importance of values in research. In the emancipatory paradigm, there are multiplicity of
realities and knowledge that are socially and historically situated. Knowledge is seen to be mediated by class, power,
gender, economic, ethnic-cultural values. O’riordan (1981) distinguishes between technocentric and ecocentric
perspectives. Technocentricism is the result of the positivist worldview and science while ecocentrism is associated
with the naturalist and emancipatory worldviews.
Technocentricists who promote limitless growth are described as cornucopians by O’riordan (1981) while Dryzek
(2013) calls them prometheans. However both authors extend technocentricism to sustainability in the forms of
environmental managerialism, ecological modernisation and sustainable development. Environmental managerialism
and ecological modernisation focus on predominantly addressing ecological issues through continuous innovation.
But sustainable development embraces ecology as well as intra and intergenerational equity. In their variety, the
above technocentric discourses span approaches ranging from expert-lead, through participatory democracy, to
unbridled free-market mechanisms for development. Underpinned by scientific rationalism, technocentric approaches
are politically and economically dominant (Dryzek, 2013). Technocentric actors include governments, bureaucrats
and technocrats. They operate at local and global levels. Local governments work with international bodies such as
WHO, the UN and other multilateral national corporations. They may also include compliant NGOs that act as
intermediaries with various communities. The normative and operational discourse by international bodies discussed
above can therefore be said to be technocentric. Similarly, the more quantitative approaches to normative and
operational level water research are technocentric (including authors like Falkenmark, Mekonnen, Hoekstra,
Smakhtin, Rijsberma, Kuylenstierna, Conforti, Contanza, Guppy, others and others). Here would also fall those who
drive the agenda of climate change.
Ecocentric approaches on the other hand question the dominance of scientific rationality and question the desirability
of perpetual economic growth. Framed by naturalists and emancipatory worldviews, they reveal and critically engage
the values that underpin normative practice and discourse and challenge man to fundamentally change consciousness
(Arne Naess (1973 and 1990). For Dryzek (2013), ecocentrism is synonymous with green radicalism because it
agitates for a rupture from the dominant technocentricism. Ecocentricism covers fields like deep ecology, critical
history, ecofeminism, ecotheology, environmental humanities and posthumanism. From the above normative and
operational level analysis therefore, the authors who exemplify ecocentricism include Shiva, Mehta, Edwards and
Hussien amongst others.

5. Academic fields
Compiling the work of several authors, the website enacademic.com (see enacademic, 2020) identifies five main
academic groups: humanities, social sciences, natural sciences, formal sciences, professions and applied sciences.
Each academic group holds several sub-groups. In turn, each sub-group holds many academic fields each of which
the authors describe in some detail. This paper referenced the groups, sub-groups and descriptions by enacademic.com
to classify the main academic fields under the worldviews discussed above. This classification will form the
horizontal dimension of the schema.
Natural and applied sciences fall in the positivist paradigm and technocentrism. They use scientific rationality,
technocrats, bureaucrats and experts. Some social sciences (those that emphasise use of quantitative methods such as
controlled experiments and statistics) are also included here. Together, these fields are responsible for engineering
water infrastructure: designing, constructing, maintaining, managing it. They also include applied sciences such as
health sciences and agricultural sciences. Multilateral organisations such as the World Bank and a range of United
Nations subsidiaries use methods of the natural and social sciences..
Humanities arguably fall in the naturalist and emancipatory worldview. Together with the critical fields in social
sciences, humanities problematise water discourse through historical and socio-cultural lenses and structures of class
and power. Together with civil society, they engage in politics through building societal movements and grassroots
democracy. Particular types of fine arts and literature viscerally reveal underlying social and environmental injustices.
Spatial design fields such landscape design, architecture, urban design and planning straddle both scientific
rationalism and the humanities. As creative fields, they offer visions of sustainable bioregions, water sensitive cities
and liveable neighbourhoods.
Locating the academic fields under their respective worldviews defines the horizontal dimension of the research
outline.
6. Outline Schema for Water Research
The above vertical dimension (see section 3.6) and academic fields in the horizontal dimension are brought together
to yield a high-level outline for water research.
See Figure 1 below.
A single cell in the in the schema below is a well-focused water research area that relates to a specific field of study
or practice. Any vertical column in the outlined schema defines a range of possible areas for disciplinary research.
Any horizontal row in the schema draws focus to a single water issue around which an IDTD team can be mobilised
by drawing competencies from relevant academic and societal partners along that row. Finally, choosing several cells
from the schema without being constrained by cell adjacency or vertical and horizontal alignment enables formation
of purposive IDTD networked research spanning a diversity of knowledge areas deemed relevant to address a unique
wicked water problem.

7. Discussion and Conclusion
Water supply is a contemporary global challenge with multiple options for disciplinary, interdisciplinary and
transdisciplinary research. But there is no generic outline schema for articulating the specificities and overlaps
between the different research directions. Through a rigorous review of existing water-related scholarship, this paper
outlines a schema that hinges on societal and environmental water scarcity to delineate a range of research options
that cover such aspects as drivers of water problems, solutions and innovations to mitigate scarcity and build
resilience. The schema allows positioning of disciplinary, interdisciplinary and transdisciplinary research. This allows
an individual or a team of researchers to locate their work vis-à-vis other studies and to identify complementary efforts
and synergies. This therefore allows quick scoping, positioning and prioritization of research endeavors while also
allowing researchers to avoid unnecessary duplication. This can facilitate collaboration and is hence valuable for
accretional bottom-up coalescing of scattered study endeavors into a networked interdisciplinary research program.
Moreover, the schema can be used to reflect on the current state of the art – for example as an aid in articulating
knowledge gaps for future research. At a broader level, the outlined schema can allow an interdisciplinary institute to
be critically reflexive about its work and assess whether it is comprehensive in scope and appropriate in focus. It can
be used to map existing areas of interest within a diverse interdisciplinary institute. Such a map would make explicit
the convergences and divergences of the interests of various people involved and thus be a useful aid to the framing
of new IDTD research endeavors. Such an exercise can also illuminate the sorts of knowledge streams that are missing
and needed to strengthen interdisciplinary research. At a national level, this can be useful in mapping the state-of-art
in water research to identify what is being over-researched and where critical gaps exist, and to come up with measures
to address any such asymmetries. This enables research managers to critically assess the field of water research
nationally to identify and focus resources where they are most needed. Moreover, the outlined schema can be a useful
tool in the setting up of a national center of excellence in water research that bring together existing relevant expertise
from several universities to undertake highly relevant IDTD water-related research that cannot be executed within the
confines of a single institution.
Water research is pulled by the enduring tension between the environment and development. This tension is mirrored
in positivist scientific rationalism on one hand and naturalist and emancipatory worldviews on the other. The schema
outlined here locates different academic fields within these worldviews. A significant value of the outlined schema is
that it readily highlights that, although various strands of discourse may be underpinned by different assumptions and
languages, they all essentially focus on the same issues highlighted in the vertical dimension. Whereas the dominant
scientific approaches can be charged with the ills of modernism, their version of sustainability begins to define
interfaces with naturalist and emancipatory paradigms. These interfaces may be manipulated to neutralize criticism
and sustain the status quo. But they may also well be used to bridge across the paradigmatic differences. It is by
engaging in these interfaces that critical scholars and practitioners can work with scientists to see past the watershed
to the problem-shed beyond.
