Water is critically important to the livelihoods of more than 1 billion people living on less than $1 a day, particularly for the 850 million rural poor primarily engaged in agriculture. In many developing countries, water is a major factor constraining agricultural output, and income of the worl...

Stochastic production frontiers of irrigated and rain-fed smallholder agriculture in Tigray, Ethiopia, were fitted to a random sample of irrigated and rain-fed plots to compare their technical efficiencies. Propensity Score Matching Method was applied to select rain-fed plots with comparable bio-...

In Ghana, inland valleys have been found to be suitable for rice cultivation and could potentially increase lowland paddy rice production. This study estimated the temporal variations of surface water resources and their spatial distribution in the Mankran watershed of Ghana through the collectio...

This paper examines the water dimensions of recent large-scale land acquisitions for biofuel production in the Ashanti, Brong-Ahafo and Northern regions of Ghana. Using secondary sources of data complemented by individual and group interviews, the paper reveals an almost universal lack of conside...

As part of their irrigation strategy, the government and non-governmental organizations (NGOs) in Malawi are actively promoting the use of treadle pumps in smallholder irrigation. The positive impact of treadle pumps on food security and poverty reduction in Malawi and elsewhere in sub-Saharan Af...

In Sri Lanka rice is grown under conditions of sub-optimal water and land availability. Thus, innovations such as the System of Rice Intensification (SRI) that can increase productivity and save resources are needed. The objective of this study was to understand how SRI was implemented on farms i...
