This paper assesses how the Huruluwewa tank (HWT) irrigation system in the North Central Province of Sri Lanka adapts to climate variability. The lessons learned in the HWT will be helpful for many water-scarce irrigation systems in the country, which bear high climate risks. Recurrent droughts are the bane of agriculture in the Dry Zone, comprisin...

Traditional tanks in arid regions of India have been working to address water demands of the public for more than 2000 years. However, recent decade is witnessing growing domestic and agricultural water demand coupled with rising encroachment and ignorance toward tanks; consequently, intensifying water shortage issues. While climate change is impac...
The century old irrigation tanks mostly found in south India account for about 1/3 of rice irrigated areas and largely benefit the small and marginal farmers. The current performance of these tanks is below the 50 percent level. Major factors contributing to their declining performance are: erratic rainfall pattern and reduced inflows (hydrology si...
Indian agricultural communities are facing a crisis driven by, among other things, skewed terms of trade and farmers’ inability to deal with increasingly adverse climatic conditions. Because agriculture continues to be the primary source of livelihood for most of India’s population, governments at all levels are under pressure to find ways to help ...
Like rest of Southern India, tanks in Tamil Nadu also suffered massive deterioration as irrigation moved towards being more atomistic and less community-managed. Tank institutions declined and what remained of these irrigation tanks evolved into mostly percolation tanks. In 2017, in the face one the biggest droughts affecting the state, Tamil Nadu ...
The overall measure of farm-level technical efficiency is generally used to derive recommendations for the use of individual inputs. In this paper, joint estimation is made of technical and individual input-use (e.g. irrigation water productivity) efficiencies. This indicates that overall technical efficiency is not an indication of the efficiency ...
