A large number of small- to medium-sized community ponds exist in most parts of the Terai region in Nepal. Such ponds could be a viable alternative for other forms of surface irrigation. But, with the lack of efficient management, many of these ponds remain underutilized. An effort was made to fa...

Irrigation subsidies have become a highly contentious issue over the years and alternative approaches and conventions have been evolved in measuring the magnitude of these subsidies. Given the fact that the capital cost is a sunk cost, this paper has used the O&M cost of the project and the gross...
