The Water and Agriculture group is working on the following linked research areas:
Water for food security
Food security is reached when people have access to sufficient and nutritious food for healthy life. Water plays an essential role in this. Firstly, to produce food an enormous quantity of water is needed. The production of a varied diet requires good water management. Secondly, access to productive use of water enhances incomes of millions of small farmers around the world. Sufficient income is a prerequisite for food security. Thirdly, access to safe drinking water and sanitation is essential to health and hence the capacity of the human body to absorb sufficient nutrients.
Our research in this area examines how and to what extent improved water management contributes to enhanced food security.

Water use for food, ecosystems services and livelihoods
With population growth pressure on land and water resources is increasing and adverse environmental impacts of agricultural intensification are becoming more acute. This is particularly true in low lying flood prone areas, wetlands and other areas with high ecological value. Often there is tremendous pressure to develop these areas for various types of land use, often at the expense of ecosystems services provided by these natural areas. Rural livelihoods depending on these services may suffer.
This research aims at finding synergies between sustainable and equitable water use for agriculture, ecosystems services and local livelihoods. Topics include integrated lowland development and management; policies and mechanisms for sustainable water use; climate change and livelihoods.

Development and improvement of irrigation and drainage systems
With climate change and growing food demand, calls by governments and donors for more investment in irrigation are getting louder. Yet, a sizeable part of irrigation systems worldwide are performing under their potential. Sometimes the schemes are only partly used or abandoned due to problems in operation and maintenance. Circumstances have changed since schemes were built and schemes may no longer be adapted to users' needs and capacities. With governments less willing and able to subsidize irrigation, farmers themselves, organized in Water Users Associations, are expected to take over and pay for operation and maintenance. They can only do so if irrigation is profitable and the systems' O&M requirements are manageable and within farmers' capabilities. Increasingly farmers engage in individual informal irrigation activities.
This research area aims at developing approaches towards sustainable and profitable irrigation and drainage development. Specific research topics include optimized design (hydraulic systems, sediment, costs) and service oriented management, farmer driven irrigation development and flood based irrigation.
