| This article examines the economics of groundwater irrigation and shallow tubewell (STW) ownership decision making, using farm-level data collected from 324 households in Nepal. STW irrigation generated a significant positive effect on rice yield and farmers’ incomes. Based on a probit model, the farm size, land fragmentation, access to electricity, and access to credit were found to significantly influence farmers’ decisions to own STWs. Although the water market benefited poor farmers, it is too small and monopolistic. Policy reforms needed to make groundwater accessible to the poor majority include effective credit programs, investments in rural electrification, and public sector support for promoting suitable pumping technologies |

| China and India face similar challenges in managing their irrigation economies. Both are developing nations with large agricultural populations, high population densities and a high proportion of agriculture under irrigation. Both are facing challenges in financing existing irrigation systems in the face of broader economic reforms. And in both countries, groundwater provides a particular challenge since it is a major source of irrigation, but with accelerating declines in both quantity and quality. Problems in financing surface irrigation systems, worries about continued groundwater table declines along with cost implications for both farmers and the energy industry, and a range of other issues have raised serious concerns over the future sustainability... |

| The Atankwidi Catchment, which lies in the White Volta Basin in West Africa, is intensively cultivated by locals for economic gains. During dry seasons, farmers irrigate their crops, chiefly tomatoes, using shallow groundwater harvested from shallow ponds they dig using simple tools like an axe, hoe, bucket and bowls. Recent expansion in cultivated areas has brought to the fore the need to estimate the volume of shallow groundwater stored in the catchment’s underlying aquifer and to what extent it can sustain the incremental growth in irrigated areas. |

| Many people still believe that India’s irrigation water mainly comes from canal irrigation systems. While this may have been true in the past, recent research shows that groundwater irrigation has overtaken surface-water irrigation as the main supplier of water for India’s crops. Groundwater now sustains almost 60% of the country’s irrigated area. Even more importantly, groundwater now contributes more to agricultural wealth creation than any other irrigation source (see Fig. 1). groundwater use has increased largely because it is a democratic resource,’ available to any farmer who has access to a pump. Accessibility has led to widespread exploitation of the resource, by farmers grateful for a reliable irrigation-water source. In turn, this has led to... |
