Setting the agenda: Climate change adaptation and mitigation for food systems in the developing world

New agricultural development pathways are required to meet climate change adaptation and mitigation needs in the food systems of low-income countries. A research and policy agenda is provided to indicate where innovation and new knowledge are needed. Adaptation requires identifying suitable crop varieties and livestock breeds, as well as building resilient farming and natural resources systems, institutions for famine and crop failure relief, and mechanisms for rapid learning by farmers. Mitigation requires transitioning to ‘low climate impact’ agriculture that reduces emissions while achieving food security, economic well-being and sustainability. Efficient interventions, incentives for large-scale shifts in practices, and monitoring systems are required. Integrated assessments of adaptation and mitigation are needed to better understand the synergies and trade-offs among outcomes

Climate change, water and agriculture in the Greater Mekong subregion

The impacts of climate change on agriculture and food production in Southeast Asia will be largely mediated through water, but climate is only one driver of change. Water resources in the region will be shaped by a complex mixture of social, economic and environmental factors. This report reviews the current status and trends in water management in the Greater Mekong Subregion; assesses likely impacts of climate change on water resources to 2050; examines water management strategies in the context of climate and other changes; and identifies priority actions for governments and communities to improve resilience of the water sector and safeguard food production

Basin closure and environmental flow requirements

A river basin is referred to as 'closed' when all its river flow is allocated to different uses. Water requirements of freshwater-dependent ecosystems, often referred to as 'environmental flow requirements', only recently started to receive attention. This 'user' is still often neglected in river basin management. This paper discusses the place of environmental flow requirements in basin water resources, examines a global pattern of closed/closing river basins and advocates the need to set environmental requirements in advance of major basin developments. It is also suggested that to ensure sustainable water resources development in the future, it is necessary to revise the content of 'basin closure' by explicitly introducing environmental flow requirements into basin water management and supporting it with relevant policies
