In the Gash Delta of Eastern Sudan, spate irrigation (flood-recession farming) contributes substantially to rural livelihoods by providing better yields than rainfed dryland farming. However, spate irrigation farmers are challenged by the unpredictability of flooding. In recent decades, the numbe...

Using smart ICT to provide weather and water information to smallholders in Africa: the case of the Gash River Basin, Sudan
This article summarizes the results of water productivity assessment in 10 river basins across Asia, Africa and South America, representing a range of agro-climatic and socio-economic conditions. Intensive farming in the Asian basins gives much greater agricultural outputs and higher water produc...

Producing more food with less water in a changing world: assessment of water productivity in 10 major river basins
Irrigation using groundwater has expanded rapidly in South Asia since the inception of the Green Revolution in the 1970s. Groundwater currently represents the largest source of irrigation in the Indus-Ganges Basin (IGB), which feeds over one billion people and provides direct livelihoods for hund...

Energy supply and the expansion of groundwater irrigation in the Indus-Ganges Basin
The irrigation services are often state-subsidized in agrarian economies for the enhancement of agricultural productivity while they also target poverty alleviation. The agriculture-dependent states of India offer representative examples of undervalued irrigation services mainly sourced by canal ...

Hydro-geology and water resources of Indus-Gangetic Basin: comparative analysis of issues and opportunities
Indian agriculture is the largest user of rainfall, surface and groundwater resources. Some of the large river systems feedings the canal systems and the groundwater aquifers, like the Indus, the Ganges, the Brahmaputra and their several tributaries have their origin in the Himalayas. A large par...

Since India gained Independence, the Krishna basin has seen an increasing mobilization of its water resources. Warnings of basin closure (minimal flow to the ocean) emerge during dry periods. Basin water development and local rural dynamics have led to a degradation of downstream ecosystems manif...
A detailed district and agro-ecoregional level study comprising the 604 districts of India was undertaken to (i) identify dominant rainfed districts for major rainfed crops, (ii) make a crop-specific assessment of the surplus runoff water available for water harvesting and the irrigable area, (ii...
