Village irrigation systems (ViSs) are vital in rural livelihood, food, and water security. VISs include small (minor) tanks and diversions (anicuts). The hydrologically linked tanks with natural drainage patterns form cascades, and beyond food and water security, they play a significant role in mitigating flood and drought impacts on communities in river basins. With anthropogenic changes, many cascades are in depilated states now. This paper finds that policy support with legal recognition to cascade-based community-level institutions promote bottom-up water and natural resources management approaches. They also facilitate investigations of ill-defined subject areas in cascade management and complex socio-political and economic issues and challenges constraining sustainable cascade based VISs operations.

A Centre Commissioned External Review (CCER) of the International Water Management Institute, Headquarters (IWMI-HQ) was carried out in Colombo in the period 20–28 May 2003. This came immediately after the reviews of the Regional Offices (Africa–by Prof. Alaphia Wright, Asia–by Prof. A. Vaidyanathan, and South East Asia–by Dr. Beatriz P. Del Rosario). The review was undertaken within the context of the (then) ongoing IWMI review and strategic planning process for future priority setting.
This book addresses groundwater governance, a subject internationally recognized as crucial and topical for enhancing and safeguarding the benefits of groundwater and groundwater-dependent ecosystems to humanity, while ensuring water and food security under global change. The multiple and complex dimensions of groundwater governance are captured in 28 chapters, written by a team of leading experts from different parts of the world and with a variety of relevant professional backgrounds. The book aims to describe the state-of-the-art and latest developments regarding each of the themes addressed, paying attention to the wide variation of conditions observed around the globe. The book consists...
Climate change remains a global challenge due to the livelihood threat it poses particularly to the marginalized or vulnerable groups in society. Though developing countries contribute the least to the cause of climate change, they remain the most vulnerable to its effects. This vulnerability is due to the over-reliance of the population on rain-fed agriculture as the main livelihood source. These, mainly smallholder farmers, lack institutional, technological, infrastructural, and economic capabilities to adapt to climate change. In addition to this, there are wide disparities in the allocation of key sustainable livelihood assets (e.g., land, livestock, farm equipment, etc.) among men, wome...
The report creates contexts for a systemic understanding of the CGIAR Transforming agric-food system (TAFS-WCA) initiative starting with work package (WP) 3 and expanding the causality effects across the other WPs of the Initiative. The main focus of WP3 is inclusive landscape management, whereby access to and proper use of land and water resources is a prerequisite to building a healthy, productive environment for resilient agri-food systems and livelihoods. Mapping synergies with other Work Packages ensure that respective contributions are integrated and impactful. The process intends to provide policymakers, researchers, and practitioners with a strategic framework to activate solutions temporarily with a stakeholder-defined suite of scenarios.
