Water and Climate Change Adaptation: Briefing Note and Questionnaire Engaging stakeholders in preparation for UNFCC COP-15 gppn global public policy network on water management Briefing Note and Questionnaire: Water and Climate Change Adaptation Engaging global stakeholders in preparation for the 15th Conference of Parties of the United Nations Framework Convention on Climate Change Stakeholder Forum ● SIWI ● http:gppn.stakeholderforum.org Water and Climate Change Adaptation: Briefing Note and Questionnaire Engaging stakeholders in preparation for UNFCC COP-15 Introduction International efforts to combat climate change have centred thus far on limiting greenhouse gas emissions by humans, particularly the burning of fossil fuels such as coal, oil and gas. These efforts reflect an attempt to tackle the cause of the problem, and are referred to in climate change terminology as mitigation. However, there is growing momentum on efforts to better understand the vulnerability of humans and natural systems to the impacts of both current climate and future climate change, and how they can prepare for and respond to changes in climate, This approach is referred to as adaptation, and recognizes that water is the primary transmitter of climate change effects on human and natural systems. Impacts of Climate Change on Freshwater The changes in global climate that have been occurring as a result of the accumulation of greenhouse gases in the atmosphere have been linked to intensification of the earth’s hydrological cycle and resultant changes in precipitation patterns which lead to increased flooding and drought. Rising sea levels, combined with reduced snow cover and widespread melting of ice will compound changes to freshwater quality, quantity and availability to human and natural systems: Water Quantity: Existing water stress in much of the world from irrigation demands, industrial pollution and water borne sewerage will be exacerbated by climate change, which for many regions will result in reduced rainfall, increasing temperatures and even drought, further reducing the availability of water for drinking, household use, agriculture and industry. In other areas, increased precipitation is projected to increase the risk of rain generated flooding. Warming temperatures and glacial melting will also increase flood risk during the rainy season for the one-sixth1 of the world’s population living in mountainous regions. Water Quality Water acquires most of its geochemical and biochemical substance during its cycle from clouds to rivers, through the biosphere, soils and geological layers. Changes in the amounts or patterns of precipitation will change the route/ residence time of water in the watershed, thereby affecting its quality. As a result, water could become unsuitable as a resource if newly-acquired qualities make it unfit for required use. Accessibility: As water quantity and quality decreases, competition for available resources will intensify. Demand for agricultural and domestic water in particular increases significantly at hotter and drier times of the year. Meanwhile, demands of industry are expected to become a greater issue in the competition for dwindling resources. In the event of decreasing water tables as a result of climate change, industrial needs will be forced to compete with agricultural and domestic water supply sources, and could lead to conflict. Water Resources Changes in freshwater quality, quantity and accessibility will have significant impacts on water resources for both human and natural systems, for example: Agriculture The main competition for water over the next century will be between agriculture and the environment. Research estimates that globally, agriculture uses between 70 to 90% of developed 1 Climate Change and Water Resources, (Wateraid May 2007) http://www.wateraid.org/documents/climate_change_and_water_resources_1.pdf Stakeholder Forum ● SIWI ● http:gppn.stakeholderforum.org Water and Climate Change Adaptation: Briefing Note and Questionnaire Engaging stakeholders in preparation for UNFCC COP-15 water supplies with the livelihoods of 70% of the world’s poor dependent largely on farming 2. Competition for water, the high investment costs and frequency of pollution of rivers and drying up of wetlands resulting from irrigation development means that the scope for expansion of irrigation is limited in many parts of the world. Increased water efficiency and enhanced agricultural productivity is therefore imperative if water availability decreases. Rain-fed agriculture is and will remain the dominant source of staple food production for most of the world’s rural poor. Many are struggling to cope with current rainfall variability, and predictions of the impact of climate change suggest this variability is likely to increase 3. Declining crop yields due to decreased water supply are likely to leave hundreds of millions without the ability to produce or purchase sufficient food supplies, making it increasingly unviable to grow certain products in certain regions, and leading to greater food insecurity, particularly in Africa. Ecosystems Environmental flows refer to the amount of water considered sufficient for protecting the structure and functioning of ecosystems and their dependent species. As climate change-induced water scarcity increases and populations grow in many parts of the world, effective and equitable management of water resources become critical for maintaining biodiversity and ecosystem health. Aquatic ecosystems in particular, such as rivers, wetlands, estuaries and coastal areas provide many services contributing to human well-being. Maintenance of the integrity and the restoration of these ecosystems are vital for services such as water replenishment and purification, flood and drought mitigation, and food production. Fish production is among the most prominent of the services from inland and marine aquatic ecosystems, with an estimated 250 million people dependent upon small scale fisheries for food and income4. Health Rising sea levels lead to salt water contamination of groundwater supplies, threatening the quality and quantity of freshwater access to large percentages of the population. In addition, heat waves associated with climate change contribute to increases in water and vector borne diseases (malaria already kills one million people annually, most of whom are children in the developing world). Reduced access to clean water for drinking, bathing and cooking, forces the rural poor to travel even further to reach supplies, and leaves the urban poor to suffer from exposure to unclean water sources. Flooding is recognized as one of the most widespread of climactic hazards, posing multiple risks to human health through slow-onset riverine floods, rapid-onset flash floods, accumulation of rainwater in poorly-drained environments, and coastal floods caused by tidal and wave extremes. Floods affect mortality; cause injuries; spread infections as well as diarrhoeal, and rodent borne diseases, and impact mental health5. Integrated Water Resources Management for Climate Change Adaptation Changes in water quantity and quality due to climate change are expected to have far reaching effects, including food availability, conflict and stability, access to and utilization of water supplies, 2 Comprehensive Assessment of Water in Agriculture, (Downloaded 16 December 2008) http://www.lk.iwmi.org/Press/releases/PR_040819_BluePaper.pdf 3 Adapting to Climate Change: Challenges and Opportunities for the Development Community, (Tearfund, 2006) http://www.ids.ac.uk/UserFiles/File/poverty_team/climate_change/adaptingtoclimatechange.pdf 4 Global Environment Outlook 4, (UNEP, 2007) http://www.unep.org/geo/geo4/report/GEO-4_Report_Full_en.pdf 5 Floods, Health and Climate Change: A Strategic Review, (Tyndall Centre, 2004) http://www.tyndall.ac.uk/publications/working_papers/wp63.pdf Stakeholder Forum ● SIWI ● http:gppn.stakeholderforum.org Water and Climate Change Adaptation: Briefing Note and Questionnaire Engaging stakeholders in preparation for UNFCC COP-15 decreased food security and increased vulnerability of poor rural farmers (especially in the arid and semi-arid tropics and Asian and African mega deltas) and biodiversity degradation. Adverse effects of climate change on freshwater systems aggravate the impacts of other stresses, such as population growth, changing economic activity, land-use change and urbanisation. Climate change also affects the function and operation of existing water infrastructure – including hydropower, structural flood defences, drainage and irrigation systems– as well as existing water management practices. Water demand is expected to grow in the coming decades with population growth and increasing affluence. Effective water resource management that takes into account ‘virtual’ water flows (the water that is used in the production processes of commodities) therefore has a critical role to play. Unfortunately however, data for assessing the impacts of climate change on water resources is not consistently available, leading to a great deal of variation in assessments of their nature and severity. In some regions (as across much of Africa and Asia 6), data is inadequate or simply doesn’t exist due to limited resources available for monitoring and assessment of water flows. Tearfund and Wateraid7 point out that the water and sanitation sectors are among the weakest performing Millennium Development Goal (MDG) sectors, with sanitation trailing furthest behind. But they are also integral to the progress made across all other MDGs, cross cutting many other policy areas including energy, health, food security and nature conservation, and making the shared governance of water resources increasingly important. International commitments in the area of Integrated Water Resources Management have not been met in many countries, and capacity in many areas for implementing IWRM plans remains low. The need for effective IWRM will become more urgent as the impact of climate change on water resources becomes more apparent. Financing for Water Management and Climate Change Adaptation It is widely recognized that water and sanitation are vital to health and education, yet despite increases in aid in the form of overseas development assistance (ODA), the share given to water and sanitation is in decline, as these areas are not prioritized by donors or recipient governments. Nor is aid reaching the poorest regions or countries. According to research by Tearfund8 less than a quarter of aid for water and sanitation goes to the Least Developed Countries as donors are increasingly investing in large-scale schemes in urban areas which are not benefiting the poor. Studies published by the UNFCCC9 in 2007 show that the additional investment and financial flows needed for adaptation to climate change are likely to amount to tens of billions of dollars annually for the coming decades. Several proposals have been put forward to identify additional sources of funding, but currently existing international financing mechanisms for climate change adaptation, such as multi - and bilateral overseas development assistance (ODA), including that available under the UNFCCC Convention, have been recognized as insufficient to the magnitude of needs10.

However little progress appears to have been made at Poznan in terms of increasing financing under the Convention, with the Fourth Review of the Financial Mechanism merely calling for developed country and other Parties to secure the successful replenishment of the Global Environment Facility so as to ensure that “adequate and predictable funding is made available for the implementation of commitments”12. In this context, funding for climate change adaptation needs to be new and additional, predictable, equitable, and adequate. Policy for Water and Climate Change Adaptation There exists a broad consensus that, so far, water resource issues have not been adequately addressed in climate change analyses and climate policy formulations, and that in most cases, these problems have not been adequately dealt with in water resources analyses, management and policy formulation. Water and its availability and quality will be the main pressures on, and issues for, societies and the environment under climate change 13; hence it is necessary to improve our understanding of the problems involved and adjust the focus of policy accordingly. Conversely, climate change policy has not been integrated into water resource policy and management at the national level – it is critical that provisions for climate resilience are integrated into national water policy plans and IWRM processes. 12 Financial mechanism of the Convention: fourth review of the financial mechanism http://unfccc.int/files/meetings/cop_14/application/pdf/cp_fm.pdf 13 Introduction to Climate Change and Water (IPCC, June 2008) http://www.ipcc.ch/pdf/technical-papers/ccw/chapter1.pdf Stakeholder Forum ● SIWI ● http:gppn.stakeholderforum.org Water and Climate Change Adaptation: Briefing Note and Questionnaire Engaging stakeholders in preparation for UNFCC COP-15 Questionnaire Name: Organisation: Role: Major Group14: The questions below are intended as merely as a guide for responses.
