India, the world's largest groundwater user, withdraws about 230 billion m3 groundwater annually for irrigation.

International Water Resources Association (IWRA) launch policy brief “Sustainable Groundwater Development for Improved Livelihoods in Sub-Saharan Africa”. At least 400 million people in Sub-Saharan Africa source their domestic water supply from groundwater. Yet this often abundant resource only accounts for around 20% of total irrigation.

Limited access to water, droughts, floods and other climatic conditions are major challenges to food security in Ghana. Over 70% of smallholder farmers in the country practice rainfed agriculture, which is highly vulnerable to rainfall variability. Flooding and waterlogging of farmlands limit land use and crop productivity.

India is on a path to reduce its carbon emission intensity with a major thrust on increasing the grid-connected solar photovoltaic capacity. However, the carbon footprint in agriculture is on the rise. Heavy subsidies for electricity and diesel to pump groundwater for irrigated agriculture, combined with lack of regulations on water withdrawal, are resulting in both groundwater over-exploitation and increased carbon emissions.

Using groundwater for agricultural production has the potential to build resilience in food insecure regions of the world. Use of groundwater can boost agricultural production, improve rural incomes and strengthen farmers' ability to withstand climate shocks and water variability.

The objective of this case study is to understand the application of ICT technologies for rural groundwater management in China, and it’s impacts on the rural poor.

In this modelling study, the researchers optimised typical dietary patterns in an Indian population sample to meet projected decreases in the availability of water per person for irrigation (blue water footprint) due to population growth (to 2025 and 2050). The optimised diets met nutritional guidelines and minimised deviation from existing patterns. Resulting changes in life-years lost due to coronary heart disease, stroke, diabetes, and cancers were modelled using life tables, and changes in greenhouse gas emissions associated with the production of diets were estimated.

Although the Ganges River Basin (GRB) has abundant water resources, the seasonal monsoon causes a mismatch in water supply and demand, which creates severe water-related challenges for the people living in the basin, the rapidly growing economy and the environment.

India is one of the world's largest food producers, making the sustainability of its agricultural system of global significance. Groundwater irrigation underpins India's agriculture, currently boosting crop production by enough to feed 170 million people. Groundwater overexploitation has led to drastic declines in groundwater levels, threatening to push this vital resource out of reach for millions of small-scale farmers who are the backbone of India's food security.

Groundwater is a vital yet threatened resource in much of South Asia. This paper develops a model of groundwater transactions under payoff uncertainty arising from unpredictable fluctuations in groundwater availability during the agricultural dry season.
