A new tool called the Environmental Sustainability Index (ESI) was developed to measure the social and environmental impacts of building a large hydroelectric power plant (HPP) on the Xingu River in Brazil. The ESI evaluates six components - aquatic habitats, aquatic fauna, fish, fishery, human life conditions, and navigability - across different seasons. It aggregates data from 35 variables into 16 indicators to calculate overall sustainability. The first ESI values showed the region's sustainability varies between wet and dry seasons. This innovative tool provides an integrated and reproducible method for comparing mitigation strategies and decisions over time. It was approved by environmental regulators and could generate new business for sustainable impact assessment.

- Future work will develop thresholds for defining HSAs and determine land use impacts on stream integrity at HSA and watershed scales.
This study investigated the fate of common contaminants of emerging concern (CECs) like hormones and antibiotics in soils amended with cattle or poultry manure under different application methods and timing relative to rain events. The key findings were:
1) Subsurface manure injection concentrated CECs in injection slits but reduced losses in runoff compared to surface application.
2) Most CEC losses occurred during the first rain event after application. Applying manure at least 3 days before rain reduced losses.
3) CEC concentrations generally decreased over time and with soil depth but varied spatially near injection slits.
4) The results suggest applying manure through subsurface injection several days before rain
Soil hydrophobicity impacts agriculture by affecting water retention and flow. Hyperspectral remote sensing shows potential for identifying and mapping soil hydrophobicity at large scales. The researchers developed methods for rapid field hyperspectral sensing and used the data to build predictive models of hydrophobicity. They also developed aerial-ground sensing networks and physics-based models to better understand hydrophobicity effects on soil properties and water flow patterns at different scales. Current work involves UAV hyperspectral imaging and field tests in the US and Israel to further develop methods for large-scale hydrophobicity assessment.
Objectives

This study aims to develop guidelines for drought preparedness and mitigation in the Skunk Creek Watershed in South Dakota. Researchers used the SWAT model to simulate water levels and identify drought triggers. Sensors were installed to monitor soil moisture, temperature, and tension. The SWAT model was calibrated and validated against historical stream discharge data. Preliminary results found the model simulated discharge reasonably well. Future work will use the model to estimate climate change impacts on water balance and identify drought-prone areas to inform water management practices and conservation. The overall goal is to develop a watershed-based plan to ameliorate impacts of drought on agriculture.

Catchment classification: multivariate statistical analyses for physiographic...IJERA Editor
The objective of this study was to determine physiographic similarity, as indicator of hydrologic similarity
between catchments located in the Upper Niger Basin, and to derive the dominant factors controlling each group
singularity. We utilized a dataset of 9 catchments described by 16 physical and climatic properties distributed
across a wide region with strong environmental gradients. Catchments attributes were first standardized before
they underwent an integrated exploratory data analysis composed by Principal Component Analysis (PCA)
followed by Hierarchical Clustering. Results showed a clear distribution into 2 major clusters: a group of
easterly flat catchments and another of westerly hilly catchments. This nomenclature came from the
interpretation of the main factors, topography and longitude, that seem to control the most important variability
between both clusters. In addition, the hilly catchments were designated to be dominated by forest and
ACRISOL soil type, two additional drivers of similarity. The outcome of this study can help understanding
catchment functioning and provide a support for regionalization of hydrological information.
This document summarizes a research project that aims to understand how weather variability and extreme events influence nutrient fluxes and greenhouse gas emissions in ex-urban forests. The approach involves in situ measurements across topographic gradients, experiments simulating extreme water pulses, and automated measurements of multiple soil greenhouse gases. Preliminary findings show that soil is the dominant source of CO2 emissions while consuming CH4, and an experiment found location and greenhouse gas type strongly influenced emissions in response to water pulses. Ongoing work includes continued automated measurements to analyze effects of weather variability on forest ecosystem processes.
This document discusses the development of an interactive web map to assess anthropogenic wastewater generation in the Tierra Blanca watershed using GIS data. The map aggregates spatial data on wastewater sources like feed yards and municipalities. Assessment techniques were used to improve Cropland Data Layer accuracy including pixel counting, Bayesian probability, and linear regression. Future plans include layers on additional wastewater sources and quality, water availability/quality in aquifers, and playas. The map will help decision-makers understand water resources and conservation options in the watershed.
This document discusses using machine learning techniques to forecast agricultural drought by incorporating high-resolution soil moisture data. It aims to 1) forecast soil water deficit index (SWDI) up to one week using support vector machines (SVM) improved with dual ensemble Kalman filters, and 2) evaluate satellite-derived soil moisture against in situ observations to assess its use in drought indices. The results show dual EnKF greatly improves SVM predictions of SWDI at different soil layers and SMAP satellite soil moisture captures the dynamics of root-zone soil moisture compared to in situ observations.
This document summarizes a study analyzing the effectiveness of conservation practices and producer adoption behavior in the Jordan Lake Watershed in North Carolina. Key findings include:
1) Water quality monitoring showed exclusion fencing reduced nutrient and sediment export from pastures by 41-64% and 73% respectively, while nutrient management reduced crop field exports by similar amounts.
2) Farmer interviews found 92.5% use conservation tillage and 62% use exclusion fencing, but nutrient management is not viewed as a conservation practice and training is disliked. Most farmers oppose water quality trading.
3) Watershed modeling estimated riparian buffers could reduce nitrogen and phosphorus loads to Jordan Lake by over 20%, but installation costs
This document summarizes research analyzing agricultural indicators and production systems in the Lake Erie basin to identify areas where improvements can be made to nutrient and soil management. The researchers used existing agri-environmental indicators to assess the risk of phosphorus and sediment losses at the watershed and basin scales. They also developed a production system typology to classify farms, recognizing that practice changes occur at the farm level. The analysis found varying risks of phosphorus losses across soil landscapes and indicated some areas had potential for reductions in nutrient surpluses and soil erosion.

This document describes the development of an integrated Riverine Environmental Flow Decision Support System (REFDSS) to evaluate the ecological effects of alternative flow scenarios on river ecosystems. Key points:
- The REFDSS was developed for the Upper Delaware River as a user-friendly tool to enable evaluation and comparison of potential habitat availability under different flow management scenarios.
- It incorporates hydrodynamic modeling of habitat variables, hydrological modeling of reservoir release scenarios, and habitat suitability criteria for various species to calculate potential available habitat.
- The REFDSS allows modification of habitat suitability criteria and addition of new flow scenarios to compare effects on fish and mussel habitat and facilitate environmental flow management decisions.

1) Environmental indicators are becoming essential tools for environmental management as they can measure environmental quality and trends over time. Many government agencies and organizations at various levels are now using environmental indicators in their work and reporting.
2) In the past, environmental management lost sight of indicators and became more focused on individual media and regulations rather than taking a more holistic view of environmental systems. This led to programs being measured by outputs like permits rather than actual environmental conditions.
3) There is now a push to develop more comprehensive environmental indicator systems to provide better information for decision making and accountability. Laws and agreements are encouraging the use of indicators and many states and organizations are working to establish robust indicator programs.

This document proposes a stepwise approach to conducting a water-energy-food nexus assessment. The assessment aims to understand interactions between water, energy and food systems in a given context and evaluate the performance of interventions. The assessment involves analyzing the current context, applying specific tools to quantify impacts, and assessing interventions' resource use efficiency and productivity versus context status. Key stakeholders should be engaged throughout to build consensus on strategic issues across sectors and scales. The assessment helps inform nexus-related strategies, policies, planning and institutional responses.

Earth observations can help monitor progress on the UN's Sustainable Development Goals (SDGs) related to water. Satellite imagery and other earth observation data can be used to monitor indicators for SDG targets like water quality, water use efficiency, integrated water resource management, and natural water capital. However, establishing an earth observation-based monitoring system faces challenges like ensuring continuity of data collection, validating indicators in different climates, building national capabilities, and overcoming reluctance to adopt more open approaches. Overall, earth observations have potential to cost-effectively monitor expanded water indicators if integrated into SDG planning and prototyped through further research.
Climate Change Impacts on the Goals of the New York-New Jersey Harbor Estuary...Sabrina Ramkhelawan
This document summarizes a report submitted to the New York-New Jersey Harbor Estuary Program (HEP) that analyzes how climate change may impact the goals of HEP's 2011-2015 Action Plan. The report was produced by students at Barnard College. It first outlines HEP's five main goals: clean up pollution; improve habitat and ecology; increase public access; support an economically viable port; and increase public education. It then identifies four key climate stressors - increasing temperature, precipitation, sea level, and extreme weather. Much of the report analyzes how each goal may be vulnerable to these stressors, such as higher pollution from more extreme rainfall, changes in habitats from rising seas and temperatures, and threats to the
This document provides an introduction to ecosystem services (ESS) and how they can be applied to problem-solving and decision-making in the Houston region. It defines ESS as the benefits that humans derive from nature, such as clean water, flood mitigation, and recreation opportunities. ESS are categorized as provisioning, regulating, cultural and supporting. The document outlines how ESS can be quantified and valued to inform policy decisions around development, economics, and the environment. It presents tools and case studies to illustrate how translating ESS into economic terms can help stakeholders make more informed choices.
This report summarizes the findings of the Phase 1 E-RISC project, which aimed to demonstrate how environmental and natural resource risks could impact sovereign credit risk. The report analyzed 5 countries and found that:
1) A 10% change in commodity prices could impact national trade balances by 0.2-0.5% of GDP, showing resource risks are relevant in the short-term.
2) A 10% reduction in biological resource productivity could impact trade balances by 1-4% of GDP, indicating medium-term risks from ecosystem degradation.
3) Countries have distinct resource risk profiles, with dependencies and exposures varying significantly. However, risks are not currently reflected in credit ratings.

A NEW TOOL TO EVALUATE SOCIAL
AND ENVIRONMENTAL IMPACTS CAUSED
BY THE BUILDING OF A LARGE HPP
A viable way to measure sustainability is, for the first time,
added to the set of tools used to evaluate impacts in
social, economic, and environmental fields caused by the
building of a large HPP. This sweeping initiative responds
to the need for attaining a measure of sustainability,
which has been increasingly embraced as an imperative
goal, worldwide. Yet actual measurements are not merely
occasional but have not been regularly added to any ef-
fort to compare performance of cost-effective strategies,

The Environmental Sustainability Index (ESI) presented
here is a measure of overall long-term ecological balance
developed and adjusted for the region surrounding a
stretch of 100 km of extension along the Xingu River in
Pará state, Brazil (Fig. 1), from now on called “Stretch of
Reduced Flow” (SRF). The SRF is a result of the general
arrangement of the HPP Belo Monte (Pará state, Brazil),
the biggest dam (11,233 MW) being built in Brazil and in
the Amazonian forest (2011 to 2015). The construction and
operation of the HPP conceived a diversion of waters from
the major reservoir (in the main channel of Xingu River), to

a secondary reservoir (in the inland), and therefore it will
cause a substantial reduction of water flow in Xingu River,
the so-called SRF (to be formed by the end of 2015).
The Environmental Analysis Team of LEME, Brazil, is re-
sponsible for the coordination of the licensing process of
this HPP. We proposed the ESI as a far-reaching, powerful
instrument that makes possible the assessment, through-
out time, of the impact of the HPP on the river natural
flow, hence on its biodiversity and human conditions be-
cause it represents a radical innovation towards a more
analytically driven approach to decision-making. For the
first time, the ongoing (since 2009) federal licensing pro-
cess of this HPP was presented with a feasible, integrat-
ed, and reproducible method (and results) to evaluate
tangible social and environmental impacts which are ac-
tually interconnected but are usually analysed only
separately.
Because there is a strong seasonality within the region,
and because we are interested on the environmental im-
pact of the formation of the SRF, we aimed for the first
ever comparison between the environmental sustainabil-
ity of rainy seasons (high waters) and of dry seasons with-
in the region in focus (Fig. 1), before and after the opera-
tion of the HPP.

FIRST EVER MEASUREMENTS
OF ENVIRONMENTAL SUSTAINABILITY
OF THE SRF REGION
The method adopted to create the ESI suited to the
region in focus based on a multiple criteria approach
presented by the “Global Leaders of Tomorrow
Environment Task Force”, during the annual meeting
of the World Economic Forum (2001)1
. This approach
allowed simultaneous analysis of social, economic,
and environmental data. A high ESI rank indicates a
high level of environmental sustainability in a particu-
lar season or site; a low ESI rank in another season or
site (comparison over time or space) signals substan-
tial problems in achieving environmental sustainabil-
ity along multiple dimensions.
Our ESI score centers upon a set of six components as-
sociated with 16 core indicators, each of which combines
one to four variables for a total of 35 underlying variables
(Fig. 2 & Tab. 1). Indicators and variables were chosen
through careful review of scientific literature, available
data, and analysis of the first results. In addition, we con-
sidered further application and future comparison with
other enterprises for a full use of the method at least in a
countrywide manner, and therefore we considered com-
monality of variables due to relevance among other li-
censing processes in Brazil.
At the most basic level, we defined the scope in concep-
tual terms and we have determined that environmental
sustainability of the SRF region is a function of the varia-
bles, linked by indicators, of the following six components:
“Aquatic Habitats”, “Aquatic Fauna”, “Fish”, “Fishery”,
“Human Life Conditions”, and “Navigability” (Tab. 1).

After building up the complete database, we standardized
the variables to make aggregation possible. We calculated
the Z score (value minus the average, divided by standard
deviation) for those variables for which high-observed val-
ues corresponded to high levels of environmental sustain-
ability (e.g. dissolved oxygen concentration). For variables
that high-observed values corresponded to low levels of
environmental sustainability (e.g. cyanobacteria concen-
tration in water) we also calculated the Z score (but we
standardized by dividing average minus the value, divided
by standard deviation). This effort to uniform data meets
the goal to have an index with a simple interpretation: high
scores means high levels of environmental sustainability
presented by the region in focus. At that point, we calcu-
lated the 16 indicators by taking the average of the con-
stituent variables’ Z scores. We then averaged the values
of the 16 indicators and calculated the normal percentile,
the ESI, for each season.
The calculation of the ESI allowed the first ever visualiza-
tion of the varying sustainability of the SRF region (among
seasons) in a multicriteria approach. The calculation of the
ESI used data gathered from 2012 to 2014 from the mon-
itoring projects executed as required by the ongoing fed-
eral licensing process of the HPP. Therefore, the first values
calculated showed not only comprehensive deployment
and viability of a new tool for a specific site but it also rep-
resents measures of reference of the environmental sus-
tainability status of the region before the formation of the
SRF. We highlight that, because it is such a novelty, we
simply did not have the time to reach its full potential and
largely apply the same reasoning to other customers or
sites. However, validation of its results, presented as
follows, was already highly significant with the federal en-
vironmental institution officially approving our innovative
approach and expecting for its continuity. With this in hand
and with the easiness to deploy it for any number of cus-
tomers or sites, we have an established plan to use this
tactic in future projects and even generate new business,
arousing new clients with this unique, feasible product.
We calculated the ESI of three rainy seasons and of two
dry ones (Fig. 3). Rainy seasons had higher scores for
“Aquatic Habitats”, “Human Life Conditions”, and
“Navigability”, as expected. On the other hand, higher
scores for “Fish” and “Fishery” were a result of higher cap-
ture when discharge decreases during dry seasons.
Interestingly, the ESI of the last rainy season (2014) was
lower than the ESI calculated for the dry season of 2012,
indicating that one cannot always link the dry seasons in
the Amazonian forest, with lower sustainability, as com-
monly thought.
Trade-offs between components were clear (while a com-
ponent "progressed" from one year to another, another
component "plunged") as were also parallelism among
components (when two or more components went "for-
ward" or "back" together, from one year to another). This
direct, fast, and integrated judgment is promising for the
future management of the required monitoring plan of so-
cial and environmental indicators in the region of the SRF
(during the test phase) with a view to identify problems. To
clarify how it works in general, and how the observed val-
ues are used, we display Z scores of indicators (Fig. 4), in
order to illustrate the midway outputs of the calculation of
the ESI.

components. The “blue area” represents the highest
observed sustainability during rainy seasons and the “orange
area” represents the highest sustainability observed during
dry ones (2012 to 2014). The grey area (intersection between
the colored areas) indicates the lowest observed
environmental sustainability of the SRF region, independently
of the season.

A NEW PRODUCT IN OUR NEW BUSINESS
UNIT READY TO DRAW NEW CONTRACTS:
SIMPLIFICATION MEANING REDUCED COSTS
Social and environmental sustainability can be measured.
While no quantity of such an intricate phenomenon can be
flawlessly calculated, the ESI presented here proved to be
remarkably powerful, valuable, and robust. Its application is a
radical change in the way we do environmental monitoring
assessment and evaluation of strategies, decisions, or ac-
tions. This instrument is one sample of how we can use our
expertise in these matters to convey more confidence to
stakeholders, clients, and environmental institutions (govern-
mental or not).
Perspectives of this method are clear: a new product line
in our new Business Unit with a brand new tool that cre-
ates a chain of comparative benchmarks of environmen-
tal settings of different sites and enterprises because it
assures the shifting of policymaking onto a more fact-
based and systematically rigorous structure. This is al-
ready added in our business model as an exclusive type
of service that only we can provide, because until now,
we are the first ones within the environmental licensing
market in Brazil with the experience and proficiency to
perform similar calculations and apply them.
Gains of this innovation are extensive. We highlight, as men-
tioned above, that we have received confirmation of deploy-
ment of the ESI in the form of the official acceptance from
the federal environmental institution upon the usage of this
new tool. We cannot express how imperative it is to acquire
this kind of validation, especially in the challenging path to
obtain a Federal License of Operation (usually, our final goal)
and to maintain it. This endorsement indicates that new
business might develop purely because customers will
search for it (thus it will generate new income as well). Value
creation for the GDF SUEZ Group to have a BU that
successfully measures social and environmental sustaina-
bility with respect to governmental licensing process can be
therefore linked to new commercial contracts ranging from
0,5 Me up to 5 Me.
Moreover, the scope of the ESI noticeably intended simpli-
fication of the entire process of environmental monitoring
which means less costs for us or our clients in the long run
(consequently making us or them more revenues) because
we tend to designate deliberation of resources solely on
variables and indicators needed for the ESI. The team of
specialists needed to execute the monitoring programs as
required by federal licensing processes reach cumulated
contract values of about 40% to 50% of the total contract.
The current business plan, also using the ESI as an outlining
tool to choose which variable should continue to be moni-
tored, is to save at least a third of that value.
Another type of simplification will also mean another de-
crease in costs: thanks to the shift towards less subjective
analysis, the final merging of results on our main types of
products (thick volumes with all-encompassing social and
environmental impacts studies) may amount to reduced
number of experts and man-hours. It is expected that a
smaller expert team will be needed to objectively analyse
the outcome of such studies, ensuing an even better and
cohesive final report.
Interestingly enough, not only the entrepreneur can benefit
from the ESI analysis and practice, but also the population
can be empowered with its findings and be more informed
when participating on debates about its own needs for de-
velopment. Finally, we point out that the ESI reveals the
prospective value of enhancements not only in the Brazilian
aptitude for data-driven pursue of sustainability and eco-
nomic growth but also the world’s capacity to do it either.
This method originated from this kind of initiative and our
application is a crucial step towards global human progress
with more sustainable environments.
