This book provides experiences from studies on agricultural water management under climate change as references for agriculture and irrigation planners, decision makers, researchers and students. Chapters 2 and 3 provide an overview of global assessment of climate change impacts and water...

Freshwater-related risks of climate change increase significantly with increasing global temperatures. Globally, the negative impacts of future climate change on freshwater systems are expected to outweigh the benefits, and agriculture and irrigation, as the largest consumers of water globally, are ...

Currently, agriculture is the biggest consumer of water globally. About 60% of global consumptive water demand is from the agriculture sector. With the world population increasing to about 9 billion, and the per capita GDP rising, the demand for domestic and industrial water will increase in future ...

Climate change is now a reality and is expected to have profound impacts on agricultural production systems, thus threatening food security. Local observational evidence of changing climate based on available historical weather data-sets is presented for selected locations in the Philippines. In...

The agriculture sector is highly vulnerable to climate change in many parts of the world. There is an increasing concern among farmers, researchers and policy makers about the potential impacts of climate change on food security and livelihoods. Researchers are using several climate change models...

Most of the aquaculture production in South-east Asia occurs in the floodplains and coastal areas that are highly exposed and vulnerable to climate change impacts and sea-level rise (SLR). This chapter presents an example of economic estimation of autonomous adaptation by shrimp and catfish farms...

Groundwater resources in transboundary aquifers may cushion climate change and other impacts of anthropogenic change through irrigation development, which in turn can enhance food security, livelihood benefits and poverty reduction in developing countries. Such resources present significant water...

Future inflow to the irrigation scheme of the Syr Darya Basin is modelled under two climate scenarios, based on outputs of International Panel on Climate Change (IPCC) core models run under IPCC-SRES A2 emission scenario. Under the GFDL99-R30-based scenario, the mean annual flow (MAF) is likely to...

Current discourse on climate change highlights the issue of uncertainty, risks and the importance of systems' resilience as a means to cope with impacts of climate change and climate variability. This chapter links the dominant approach of uncertainty as presented in the climate change discourse...

This chapter reviews the global literature on impacts of climate change on agriculture and prospects for adaptation. Sensitivity of agriculture to climate change varies across the globe. Developing countries, where more than 800 million people are already undernourished, will be hardest hit. We...
