5. P oliticians, economists and even some natural scientists have tended to assume that tipping points1 in the Earth system — such as the loss of the Amazon rainforest or the West Antarcticicesheet—areoflowprobabilityand little understood. Yet evidence is mounting thattheseeventscouldbemorelikelythanwas thought,havehighimpactsandareintercon- nected across different biophysical systems, potentiallycommittingtheworldtolong-term irreversible changes. Herewesummarizeevidenceonthethreat of exceeding tipping points, identify knowledge gaps and suggest how these should be plugged. We explore the effects of such large-scale changes, how quickly they might unfold and whether we still have any control over them. In our view, the consideration of tipping points helps to define that we are in a climate emergency and strengthens this year’s chorus of calls for urgent climate action — from schoolchildren to scientists, cities and countries. The Intergovernmental Panel on Climate Change (IPCC) introduced the idea of tipping points two decades ago. At that time, these ‘large-scale discontinuities’ in the climate system were considered likely only if global warming exceeded 5 °C above pre-industrial levels. Information summarized in the two most recent IPCC Special Reports (published in2018andinSeptemberthisyear)2,3 suggests that tipping points could be exceeded even between1and2 °Cofwarming(see‘Tooclose forcomfort’). Ifcurrentnationalpledgestoreducegreen- house-gas emissions are implemented — and that’s a big ‘if’ — they are likely to result in at least 3 °C of global warming. This is despite the goal of the 2015 Paris agreement to limit warmingtowellbelow2 °C.Someeconomists, Thegrowingthreatofabrupt andirreversibleclimate changesmustcompel politicalandeconomic actiononemissions.

However, if tipping points are looking more likely,thenthe‘optimalpolicy’recommenda- tionofsimplecost–benefitclimate-economy models4 aligns with those of the recent IPCC report2 . In other words, warming must be limited to 1.5 °C. This requires an emergency response. Icecollapse We think that several cryosphere tipping points are dangerously close, but mitigating greenhouse-gas emissions could still slow downtheinevitableaccumulationofimpacts and help us to adapt. Research in the past decade has shown that the Amundsen Sea embayment of West Antarcticamighthavepassedatippingpoint3 : the‘groundingline’whereice,oceanandbed- rock meet is retreating irreversibly. A model studyshows5 thatwhenthissectorcollapses,it coulddestabilizetherestoftheWestAntarctic icesheetliketopplingdominoes—leadingto about3metresofsea-levelriseonatimescale of centuries to millennia. Palaeo-evidence shows that such widespread collapse of the WestAntarcticicesheethasoccurredrepeat- edly in the past. The latest data show that part of the East Antarctic ice sheet — the Wilkes Basin — might be similarly unstable3 . Modelling work suggeststhatitcouldaddanother3–4 mtosea level on timescales beyond a century. The Greenland ice sheet is melting at an accelerating rate3 . It could add a further 7 m tosealeveloverthousandsofyearsifitpasses a particular threshold. Beyond that, as the elevation of the ice sheet lowers, it melts further,exposingthesurfacetoever-warmerair. Models suggest that the Greenland ice sheet couldbedoomedat1.5 °Cofwarming3 ,which could happen as soon as 2030. Thus, we might already have committed future generations to living with sea-level risesofaround10 moverthousandsofyears3 . But that timescale is still under our control. The rate of melting depends on the magni- tude of warming above the tipping point. At 1.5 °C, it could take 10,000 years to unfold3 ; above2 °Citcouldtakelessthan1,000years6 . 592 | Nature | Vol 575 | 28 November 2019 Comment An aeroplane flies over a glacier in the Wrangell St Elias National Park in Alaska.

About 17% has been lost since 1970. The rate of deforestation varies with changes in policy. Find- ing the tipping point requires models that include deforestation and climate change as interacting drivers, and that incorporate fire and climate feedbacks as interacting tipping mechanisms across scales. With the Arctic warming at least twice as quickly as the global average, the boreal forest in the subarctic is increasingly vulnerable. Already, warming has triggered large- scale insect disturbances and an increase “Theclearestemergency wouldbeifwewere approachingaglobal cascadeoftippingpoints.” FRANSLANTING/NAT.GEO.IMAGECOLLECTION Nature | Vol 575 | 28 November 2019 | 593 ning to irreversibly thaw and release carbon dioxideandmethane—agreenhousegasthat isaround30timesmorepotentthanCO2 over a 100-year period.

Source: World Meteorological Organization / Flickr ARTICLE New elevation data triple estimates of global vulnerability to sea-level rise and coastal flooding Scott A. Kulp1* & Benjamin H. Strauss 1 Most estimates of global mean sea-level rise this century fall below 2 m. This quantity is comparable to the positive vertical bias of the principle digital elevation model (DEM) used to assess global and national population exposures to extreme coastal water levels, NASA’s SRTM. CoastalDEM is a new DEM utilizing neural networks to reduce SRTM error. Here we show – employing CoastalDEM—that 190 M people (150–250 M, 90% CI) currently occupy global land below projected high tide lines for 2100 under low carbon emissions, up from 110 M today, for a median increase of 80 M. These figures triple SRTM-based values. Under high emissions, CoastalDEM indicates up to 630 M people live on land below projected annual flood levels for 2100, and up to 340 M for mid-century, versus roughly 250 M at present. We estimate one billion people now occupy land less than 10 m above current high tide lines, including 250 M below 1 m. https://doi.org/10.1038/s41467-019-12808-z OPEN 1 Climate Central, Palmer Square #402, Princeton, NJ 08542, USA. *email: skulp@climatecentral.org NATURE COMMUNICATIONS | (2019)10:4844 | https://doi.org/10.1038/s41467-019-12808-z | www.nature.com/naturecommunications 1 1234567890():,;

Between now and 2050, global water consumption is expected to increase by 25%, due to the growing number of households, the growth in industrial production and agricultural expansion and intensification. Growing water demand and —in some regions— declining precipitation will increase the pressure on the available water resources, resulting in high levels of water stress in many regions.

Moderate High Very high No data A high likelihood of water stress, strong population growth with a large share of young adults, and low income per capita, can be associated with water-stress-related migration. By 2050, these factors may all affect migration in many Sub-Saharan dryland regions. Drylands African drylands Millions of people live in coastal areas within the reach of 1m sea level rise. Sea level rise, therefore, will eventually become a potential driver of migration in areas without the capacity to help people adapt. Hotspots of migration may be found especially in Southeast Asia, the Small Island Developing States and in Africa, based on projected coping capacity and number of people at risk. 2015 2050 36% 64% 59% 41% 33% 2% 76% 42% 9% 96% 83% 64% 168% Drylands compared to global averages Strong population growth, especially in combination with a large share of young adults, affects migration processes.

Soil subsidence Slums in risky locations Growing economy Extreme precipitation Disappearing mangroves Sea level rise River flooding Storm surges and coastal flooding Flood risk increases mainly due to population and economic development Overall, more extreme precipitation will increase the risk of river flooding. Without additional flood protection and following the projected strong increase in economic value in flood-prone areas, the focal point of damage will shift to Asia. In 2010, around 1 billion people around the world were living in flood- prone areas, potentially exposed to either river or coastal flooding. This number is projected to increase to over 1.6 billion by 2050.

URBANISATION CHANGES GLOBAL VULNERABILITY In the urbanising world, cities will increasingly become centres of population growth and economic development. By 2050, 70% of the world population is projected to live in an urban environment, and the 600 major cities in the world are expected to provide 60% of global GDP. The global urban area is expected to expand by more than 70%, not only in riparian and coastal areas and in deltas, but also in water-stressed regions, such as drylands. By 2050, 70% of the global population will be living on 0.5% of the global land area. The challenge of inclusive urban development Today, about one billion people are living in urban slums. The rapidly growing urban population strongly increases the pressure on local resources, local environmental conditions, food availability, labour opportunities, and public services. Reducing inequality, inse- curity and poverty in cities may be some of the major challenges, on the path towards 2050. Because of continued global urbanisation, water-related risks will increasingly be concentrated in cities. 2120 THE GEOGRAPHY OF FUTURE WATER CHALLENGES 1 SETTING THE SCENE THE GEOGRAPHY OF FUTURE WATER CHALLENGES Cities Flood Risk Hotspots

Informal settlements are the most exposed In many cities, especially in developing countries, the inhabitants of informal settlements make up more than 50% of the urban population. Water- and climate-related disasters disproportion- ately affect people living in informal settlements. The number of people in flood-prone areas in the developing world is expanding rapidly.

Today, nutrients mostly end up in surface water. The increase in nutrient emissions may lead to algal blooms and deoxygenation, affecting the ecological quality as well as economic activities in these waters, such as fisheries, aquaculture and tourism. Lack of access to clean drinking water and lack of sanitation are two of the major causes of human illness and mortality. In combination, their impact leads to almost 800,000 human deaths, annually, in low- and middle-income countries. This is far more than the number of annual casualties from flooding, drought, or violent conflict. One in eight people in the world have no access to clean drinking water and almost one in three lack basic sanitation facilities Although access to clean drinking water and sanitation facilities has improved over the last decades, large differences remain between world regions. For instance, although since 1990, 2.6 billion people have gained access to clean drinking water, today 660 million people are still without, especially in Sub-Saharan Africa. In addition, at least 1.8 billion people around the world use a drinking water source that is faecally contaminated. Improving sanitation in Asian and African countries is one of the major challenges, for the coming decades. In Africa, diseases such as diarrhoea are mainly caused by contaminated drinking water and poor sanitation, and are responsible for over 10% of infant mortality, which is 25times higher than in developed countries. Although major improvements have been made, globally, one in eight people still lack access to clean drinking water, and one in three lack adequate sanitation facilities.

Under the Business-as-usual scenario, total agricultural production is expected to increase by 70%, mainly due to more food and feed production and more energy crop production. These increases are projected to be about 10% lower than they would have been without climate change. This is mostly due to water shortages and too high temperatures. Especially the agriculture in tropical and subtropical regions are projected to be affected. Twenty percent of the global agricultural area is irrigated, which represents 40% of the total in agricultural production. The remaining area (80%) fully depends on precipitation. Water is a prerequisite for crop production. Water shortages directly lead to reduced crop production. In water-stressed areas, agricultural production levels can be increased by improving water management and increasing water efficiency (‘more crop per drop’). Without improved water management, rainfed and irrigated agriculture are expected to experience substantial yield gaps by 2050.

This is especially the case for the river systems of high ecological quality of the Amazon and Congo, where hydropower potential would be close to zero if ecological quality is to be preserved. If all economic potential would be utilised, an estimated 8 million people could be at risk of displacement.

Decrease in freshwater ecosystems with high levels of biodiversity Tropical regions include the most biodiverse river basins. High- quality ecosystems in these regions, however, are already severely affected and will further decline in quality, between now and 2050. The strongest decline in quality is projected for Sub- Saharan Africa and parts of Latin America and Asia. In developed regions, such as Europe, the United States and Japan/Oceania, most of the decline in quality has already occurred.

Municipalities are responsible for the groundwater level in urban areas to preclude or limit, as far as possible, any structurally adverse influence on the water level (too high or too low). A unique function carried out by the regional water authorities consists in “keeping the territory dry”. This function is at the heart of the Dutch physical “polder – reclaimed land – approach”. The Dutch word polder refers to areas of ground that are lower than the surrounding waters where the water level is artificially regulated. In a broad sense, it may refer to all areas that have been reclaimed from the water. The Netherlands has 3 891 polders, and half of the total polder surface area in Europe is on Dutch soil.8 Intensive and systematic drainage has been critical to protect the Dutch population and economy in reclaimed areas. Such a function is separate but inherently linked to the existential risk of flooding of low-lying areas that the Netherlands faces. Regional water authorities are responsible for this backbone function of maintaining the watercourses, monitoring water levels and pumping to maintain the required level (Figure 1.6). Through this function, they also create the “natural infrastructure” for urban development, economic growth and recreation, effectively enabling, implementing and operating the communities’ spatial and land-use decisions.

Regional water authorities are responsible for operational management, including planning, licensing discharges, enforcement and evaluation. They also oversee urban wastewater treatment. Responsibility for groundwater quality is linked to broader soil protection policy, the implementation of which belongs to municipalities and provinces. Figure 1.7. Institutional mapping for water quality management Sewerage and wastewater treatment Wastewater treatment has become a major component of regional water authorities’ tasks and revenues in recent decades. They currently manage about 350 wastewater treatment plants for the treatment of urban wastewater coming from households and businesses (van Rijswick and Havekes, 2012). They can contract out services (e.g. operation and maintenance tasks) to the private sector. In one specific case, a wastewater treatment plant has been based upon a BOT (Build, Operate and Transfer) contract. To carry out these responsibilities, regional water authorities charge a wastewater treatment fee, and both regional water authorities and the state charge a pollution tax for direct discharges into surface water.

The same regulation obliges each municipality to ensure that wastewater discharged from premises situated within its territory is collected in a public sewer and transported to the wastewater treatment plant. The municipality can cover the costs incurred by means of a sewerage tax. This municipal responsibility is closely linked to the regional water authorities’ duties associated with water quality and wastewater treatment as the public sewer is connected to regional water authorities’ wastewater treatment plant (the so-called wastewater cycle). Figure 1.8. Institutional mapping for sewerage and wastewater treatment Recently, targets for wastewater treatment have been increasingly influenced by the river basin management plans developed under the EU Water Framework Directive, instead of independent national and provincial policies. The 2011 Administrative Agreement on Water Affairs includes options for a more cost-effective organisation of wastewater treatment, ranging from further co-operation between municipalities and regional water authorities in the collection, transport and treatment of wastewater, to joint collection of taxes.

INTERLOCKING WATER MANAGEMENT FUNCTIONS IN THE NETHERLANDS – 41 Drinking water supply The Drinking Water Act sets up the organisation of the drinking water supply in the Netherlands and entrusts government bodies with the responsibility to ensure the sustainable security of the public drinking water supply (Figure 1.9), with the central government playing a central role. The responsibility for supplying drinking water is entrusted to ten drinking water companies (previously more than 200). These are semi-public bodies operating under private law with their shares owned by the provinces and municipalities. Therefore, rather than levy a “tax” they charge a “price” for the drinking water they supply to households and firms. In 2004, parliament banned private sector provision from water supply, but in practice, drinking water companies contract out many services (e.g. customer relations and repairs) to the private sector.

65. Dutch River Region 4 million Rural Just above EUR 2.3 billion Extremely high water levels. That is the greatest challenge the river region in the Netherlands faces today. In 1993 and 1995, water levels in the Netherlands reached a critical level, weakening the dikes to the point of collapse. A quarter of a million inhabitants had to be evacuated, along with one million cattle. As heavy rainfall is becoming more common – and will become even more so in the future – the Dutch government is continually working on ensuring the safety of the river regions through programmes such as Room for the River. Reinforcing dikes is not an adequate solution. In order to drain excess water into the sea, measures must also include widening and deepening rivers. At more than 30 locations, the Room for the River Programme allows rivers more space, for example by moving dikes, digging secondary channels and deepening flood plains. The Room for the River Programme uses a globally innovative approach to protect areas against river flooding. Giving the river more room not only protects the river regions from floods but also improves the overall quality of the area, with new nature and recreational areas as an added bonus. In short, an integrated approach improves both safety and spatial quality. Multiple Dutch partners including central government, and local provinces, municipalities and water boards, companies and NGOs are implementing the Room for the River Programme. This close cooperation between national and regional governments ensures support and reduces the risk of delays. Room for the River is a pilot programme for the Dutch Delta Programme, which is designed to prepare the Netherlands for extreme natural events. The main objective of this programme is to make water safety and freshwater supplies sustainable and predictable by 2050. The Dutch Delta approach is based on five Ds: Delta Act, Delta Fund, Delta Commissioner, Delta Decisions and Delta Programme. The so-called Delta Decisions, for example guide the concrete approach to the Rhine- Meuse delta with regard to water storage and drainage, and the need for new dams or dikes. www.ruimtevoorderivier.nl/english THE NETHERLANDS ROOM FOR THE RIVER Integrated approach governance and cooperatIon wIth stakeholders 12

66. Bangladesh Delta 155 million Rural, with several rapidly urbanising cities Just above EUR 7.65 million Bangladesh, encompassing the Ganges-Brahmaputra- Meghna river systems, can in many respects be considered one of the most dynamic deltas in the world. Huge amounts of water and sediment often exceed the carrying capacity of Bangladesh’ rivers. Cyclones and coastal ﬂoods, intensiﬁed by climate change effects, and a range of socio-economic trends, pose additional challenges. The Bangladesh Delta Plan 2100 (BDP2100) attempts to address these issues by developing a long term, holistic delta vision and adaptive strategy. Amongst socio-economic trends are a rapidly increasing population and a growing demand for food. The already high pressure on available land adds to the complexity of water-related problems in the Bangladesh Delta, which all need to be addressed in order to support sustainable living conditions and continued economic growth. The Bangladesh Delta Plan aims to deliver an umbrella development vision, strategy and implementation plan that can act as a frame of reference for new governmental policy, thereby supporting the integration of existing sectoral development plans. At the same time it aims to provide anchorage for numerous on-going projects and no-regret measures to delta challenges in the short term. A range of stakeholders is involved in an interactive manner, ensuring the necessary institutional support for the development and implementation of the programme. BDP2100 links with the Five Year investment plans, which are coordinated by the Government of Bangladesh. Importantly, the Bangladesh Delta Plan will build on insights from the Dutch Delta Programme and the Mekong Delta Plan. www.bandudeltas.org BANGLADESH INTEGRATED DELTA PLANNING long-term approach vs. short-term measures cooperatIon wIth other government levels and stakeholders Integrated approach 13

67. Nile Delta 10 million Urban and rural Just above EUR 2.4 million The Nile delta is heavily populated, with up to 1,600 inhabitants per square kilometre. The Nile delta coastal zone encompasses more than 40% of Egypt’s industries and hosts vital centres for tourism, agriculture and fish farms. By the year 2075, a coastal area of about 500 km2 will be vulnerable to flooding. The sandy barrier, separating the inland lakes from the sea, is very narrow and low lying, presently subject to strong erosion. A UNDP report on climate change impacts estimates that hundreds of billions of Egyptian pounds, about 2 to 6% of future gross domestic product, could be lost from effects of climate change on water resources, agriculture, coastal resources and tourism. Thousands could die from air pollution and heat stress. Millions could lose jobs in agriculture as the result of climate change. In a middle scenario of sea-level rise, about 40 km2 of agricultural land will be lost by the year 2060. The Egyptian-Dutch High Level Water Panel, established 38 years ago, addresses these very urgent coastal zone challenges. Dialogues, knowledge exchange sessions and preparatory studies led to a public procurement for the development of an Integrated Coastal Zone Management strategy (ICZM) and a shoreline management plan for the Egyptian Mediterranean Coast from the Libyan border to the Gaza border. It should recognise, incorporate and address the concerns of all stakeholders through a well-defined and structured participatory approach. Next to the tremendous natural challenges there are also a number of institutional and legal challenges. The institutional framework for addressing responsibilities in Egypt is complex and sometimes unclear. Cooperation among agencies is limited. The ICZM strategy must incorporate all required legislative and institutional changes that would facilitate the adoption, buy- in, and seamless development and implementation. The project, with a total budget of EUR 2.4 million, will be funded by Europeaid and should start by the end of 2014 and be finished within 30 months.

68. Ayeyarwady Delta 6.6 million +3 m Rural The Ayeyarwady Delta in Myanmar is extremely fertile. The area, which is plagued by floods, salinity and erosion, can play an important role in the economic development of this Southeast Asian country. The first step is to assess the vulnerabilities and, in particular, the resilience of the delta. At about three metres above sea level, the delta’s sediment plays a dominant role in the large-scale cultivation of rice. The delta region is densely populated and is dotted with fishing communities in villages and market towns, mostly located along the rivers and streams. That is why the destruction caused by Cyclone Nargis in May 2008 was so catastrophic, causing nearly 140 thousand casualties and severe economic damage. Myanmar has asked the Netherlands to take the lead in drawing up an adaptive, integrated water management plan for both the delta and the rest of the country to cope with Myanmar’s expected huge economic growth and increasing pressure on water resources as a result of this. Delta Alliance Partners Deltares and Alterra are conducting a Vulnerability and Resilience Assessment Ayeyarwady Delta study, which is financed by the Global Water Partnership (GWP) and Bay of Bengal Large Marine Ecosystem (BOBLME). The Ayeyarwady Delta is currently still, for the most part, underdeveloped. Uncoordinated exploitation of its resources in some areas may pose serious threats to the health of the delta. Effective, cross-sectoral management of the water system, in which local stakeholders are involved, will lead to sustainable solutions in the long term. The list of problems may seem long: Mangroves are cut down for fuel, there is overfishing, river bank erosion and deterioration of water quality as a result of salinisation. However, by applying Integrated Water Resources Management (IWRM), the delta can be used by the local people without compromising the integrity of these systems or overexploiting their natural resources.

69. Beira 0.6 million Urban Just above Approx. EUR 2 million Beira and Rotterdam: two low-lying cities in densely populated deltas with ports serving a massive hinterland. People keep flocking to Mozambique’s seaport and settling in low-lying areas that are not fit for habitation. Waterborne diseases, especially malaria, are rampant and the city’s infant mortality rate is dramatically high. What can Beira learn from its Dutch counterpart? Focusing solely on water safety and water supply in these neighbourhoods means you are only addressing part of the problem. In addition to water safety, the integrated approach of the Beira Master Plan 2035, which has been commissioned by the Beira Municipality and drawn up in consultation with all stakeholders in the city, aims to stimulate both land development and economic growth. One important insight and result gained during the development process of the Beira Master Plan is the need for a public- private Land Development Company (LDC). A company responsible for site preparation and for allocating suitable parcels of land for housing and business purposes. The Beira Municipality drew up the master plan in association with a Dutch consortium, aided by funding from the Dutch Global Water programme. The establishment of the LDC, again with help from the Netherlands, is currently underway. The next step is preparing land development business cases aimed at generating concrete investment projects. At the request of the Beira Municipality, Dutch experts will remain actively involved. Detailed financial engineering and the inclusion of crucial development partners will be the next step after that.

70. Vistula and Oder Delta 2 million Urban and rural -1.8 m to +2.5 m Poland is a country of water, although it does not have a reputation as such. Almost all major Polish cities are located by the sea or a river and are directly influenced by water. Sometimes, as is the case with the Vistula and Oder Rivers, which run from the mountains in the south to the Baltic Sea and the low- lying, flat deltas in the north, the influence of water is too great. The one-dimensional river system set up in the past is highly susceptible to flooding. In the last century, various Polish rivers were canalised and subsequently poorly maintained. Water management was considered an architectural problem, with concrete as the solution. Little attention was paid to the natural behaviour of rivers, resulting today in flooding problems causing annual flood damages of up to EUR 3 billion in 2010 alone. In addition, cities such as Warsaw and Cracow are unable to exploit the social, economic and ecological potential of their rivers to the full. Awareness that things can and must change is gaining ground in Poland, which is also being affected by climate change. Economically, the Central European country is doing well. Poland is reaping the fruits of EU membership, also in terms of knowledge exchange. There are valuable lessons to be learned from the Netherlands and the Dutch Delta Programme in terms of its holistic, integrated approach to spatial planning and water management. In the coming years, aided by Dutch knowledge and innovation and European funding, efforts will focus on ensuring water safety in the form of infrastructure, retention and limiting building in areas susceptible to flooding. This alternative approach will make room for nature while creating opportunities for tourism, recreation and nature development, both in flood plains and on city shores.

71. Mekong Delta 17 million (expected shrink to 15 or growth to 30 million) Urbanisation 28% Greater parts + 1.5 m In the past decades, the Mekong Delta, with its rich land and water resources, successfully developed into the granary of the country and turned Vietnam into one of the leading rice exporters globally. On the other hand, the economic development of the delta lags behind other regions in the country. In its present state, the Mekong Delta is very vulnerable. Floods, droughts and salinity are dominant problems, hampering a prosperous and sustained economic development. Inspired by the experiences in the Netherlands, the Government of Vietnam expressed the strong intention to work towards a Mekong Delta Plan for a safe, prosperous and both economically and environmentally sustainable development of the delta. It presents a vision to use the comparative advantages of the delta and focus on agro-business industrialisation. Organisation of the agricultural producers enables a better position to reduce transaction costs, platforms for more sustainable land and water resources management, improvement of product quality and competitiveness. Diversification over the provinces is necessary to adapt as much as possible to available land and water resources. Important examples are a saline coastal zone with room for aquaculture integrated with mangrove restoration and in the upper delta controlled flooding with water retention and fish farming in the flood season instead of a third rice crop. Still, large-scale measures to guarantee flood protection and fresh water availability may be required when climate change causes persisting sea level rise and droughts. The plan offers an assessment framework for government, donors and international financial institutions for moving from planning to implementation. The plan enjoys broad support – from the World Bank, the Asian Development Bank, the United Nations and countries such as Australia and Germany.

72. Upper valley of the Cauca River 4,5 million Rural and urban +1,000 to +1,200 m Approx. EUR 2.5 million Inundation in the Cauca Valley has caused major socio- economic damage. As the valley is an important agricultural region representing the heart of Colombia’s sugarcane industry, flooding also affects Colombia’s national economy. The challenge is to limit the risk of flooding from the river and tackle the problem of insufficient drainage while paying sufficient attention to river ecology recovery. This requires balancing the interests of a large number of stakeholders. Due to the flat nature of the Cauca Valley, the area suffers from frequent flooding, the last of which occurred in 2011. The ministry, the local councils and the farmers own- ing land adjacent to the river are all responsible for flood safety, which makes the process of reaching agreements far from easy. The economic interests of the sugarcane farmers are great. To strike the right balance between the desired level of safety and a healthy river ecosystem it is vital that all stakeholders participate in the development and implementation of a flood risk management plan. The Regional Autonomous Corpora- tion of the Cauca Valley (CVC) plays a central role in this initiative. With support from a Dutch consortium, CVC experts analyse present water safety levels and assess the effects of potential measures. They draw up a master plan using the experience from the Dutch Room for the River Programme. This includes an active participation of stakeholders and an integrated approach. Dutch experience has shown that stakeholders need to be involved in an active and timely manner. It is important to provide the right level of detail during the development process, moving from general concepts to concrete actions. Ulti- mately, the individual landowners and local councils are responsible for the implementation of structural or physical measures. The CVC can assist in the implementation of non- structural measures such as subsidy programmes, training programmes, regulation and enforcement. The project also includes searching for funding from external sources, such as the World Bank or the Inter- American Development Bank.

73. North East region USA NYC 9.5 million, New Jersey 8.8 million Urban 2.5 metres (lowest point NYC) USD 930 million Hurricane Sandy painfully clarified the implications of climate change for the north-eastern region of the United States, exposing the vulnerabilities of the area. Since then the affected region has not just been rebuilt, but solutions are being sought that are in line with the natural and socio-economic characteristics of the region. Not a plan, but a culture change. In the autumn of 2012, 650,000 homes and hundreds of thousands of companies in the largest metropolis of the nation were damaged or destroyed. In response, President Obama appointed the Hurricane Sandy Rebuilding Task Force in order to deliver aid, help and respond effectively and coordinate the rebuilding of the New York – New Jersey region. To become more resilient to climate change the Sandy Task Force, together with philanthropy, set up an ambitious project: Rebuild By Design (RBD). After Hurricane Sandy revealed alarming infrastructural, environmental and social vulnerabilities, RBD assembled 10 teams (out of 148) of architects, engineers, planners and environmental scientists to undertake a regional research-intensive design process, identifying environmental concerns and developing strategies that will have a significant impact on the region and its communities. RBD is positioned not just to rebuild after the storm, but also to design a more sustainable and resilient region over the long term. The designs combine innovation and regional strategy with location- specific, customised solutions. Each design team is made up of a coalition of local stakeholders including government officials, entrepreneurs, residents, researchers, NGOs and other organisations. This level of cooperation is unprecedented and has a strong Dutch flavour. The same is true for the innovative designs – with members in six out of 10 teams, the Dutch are well represented here, too. The winning Rebuild by Design projects were announced in June 2014. The city of New York and the states of New York and New Jersey are responsible for implementation of the projects. An initial billion dollars of federal funding has been received for the realisation of the six projects. www.rebuildbydesign.org Integrated approach InnovatIon fInance and ImplementatIon supported analysIs NEW YORK (USA) REBUILD BY DESIGN AFTER HURRICANE SANDY 16

Climate change adaptation benefits InThe San Francisco Bayareaare maintained several monitoring networks bydifferent organizations, e.g.waterqualityin some Nature reserves bythe U.S. Natural Park services,waterqualityand sediment of the Bay Area by SFEI, water levels of the Bat area by the Army Corps of Engineers, groundwater levels at random locations bythe USGS and many more. Monitoring efforts could be improved after a discussion about needed monitoring objectives, followed by evaluating the existing networks. It’s clearthat monitoring need to be improved in this time of Climate Change and Sea Level. Therefore all organizations should worktogether and design one ‘water and subsurface’ network, strengthen each otherandinagreementwiththeobjectives.Inthefollowingtableallmonitoringtopicsaresummarized. Of course, an optimized integral monitoring can be partly based on existing sites. Eutrophication of the Bay Area example: To understand this process Bay water need to be sampled at different locations and depths (condition monitoring). To understand this condition several other impacts need to be monitored at the same time: the amount and quality of waste water discharge into the Bay, the amount and quality of stream discharges, the influence of Sacramento River, the temperature of the Bay, and the interaction with Bay dredge. Towards one integrated and public accessible monitoring network for all water and subsurface data Rain, evaporation, groundwater recharge • E.g. Lysimeter network (monitoring groundwater recharge) Groundwater • Design Bay area wide groundwater network for: – Groundwater levels and hydraulic heads – Groundwater quality – Fresh-salt gradients Rivers, streams • Design Bay area wide network: – Discharge quantities in time – Quality – Aquatic ecology Storm drainage pipes at Bay shoreline • Map and categorize outlets: – Monitor quantity and quality of selection Urban flooding (including transport lines) • Where, how much and when (camera’s) Bay water • Optimize level, quality, salinity, temperature, water depth and sediments monitoring sites if needed. Making use of Bay model • Monitor ecological and morphological state of marshes and mudflats Waste water treatment plants • Map locations WWTP’s and pipe outlets. Monitor: – Discharge , quality and temperature Groundwater pumping • Map all locations and categorize: drinking water, industrial, irrigation, infrastructure (BART tunnels, basements, parking garages) – Determine discharge quantity. quality and outlet Subsidence • Using Lidar or satellite images and extensometers All data in one web based database.
