Watershed management (WSM) is the most widely adopted technology in developed as well as developing countries due to its suitability across climatic conditions. Watershed technology is suitable to protect and enhance soil fertility, which is deteriorating at an alarming rate with agricultural intensification in high as well as low rainfall regions. Of late, WSM is considered as an effective poverty alleviation intervention in the rain fed regions in countries like India. This paper aims at providing a basic watershed policy and implementation framework based on a critical review of experiences of WSM initiatives across South Asia. The purpose is to provide cross learnings within South Asia and other developing countries (especially Africa) that are embarking on WSM in recent years.
Countries in the region accord differential policy priority and are at different levels of institutional arrangements for implementing WSM programmes. The implementation of watershed interventions is neither scientific nor comprehensive in all the countries limiting the effectiveness (impacts). Implementation of the programmes for enhancing the livelihoods of the communities need to strengthen both technical and institutional aspects. While countries like India and Nepal are yet to strengthen the technical aspects in terms of integrating hydrogeology and biophysical aspects into watershed design, others need to look at these aspects as they move towards strengthening the watershed institutions.
Another important challenge in all the countries is regarding the distribution of benefits. Due to the existing property rights in land and water resources coupled with the agrarian structure and uneven distribution and geometry of aquifers access to sub-surface water resources is unevenly distributed across households. Though most of the countries are moving towards incorporating livelihoods components in order to ensure benefits to all sections of the community, not much is done in terms of addressing the equity aspects of WSM.

Sub-Saharan Africa faces an enormous challenge in meeting the basic needs of a population that will nearly triple between now and the end of the twenty-first century. Managing water effectively, sustainably, and equitably will be a critical component for meeting this challenge, especially in the context of the Sustainable Development Goals (SDGs). We focus on green water (i.e. the water that comprises evaporation and precipitation flows), rather than blue water (i.e. the liquid water flowing in rivers, lakes, and aquifers), since green water is primarily used for food production. We examine three key insights into green water management at their relevant spatial and temporal scales: farm-based food production using the vapor shift (annual, local); landscape and ecosystem interventions (multi-year, national/regional), and moisture recycling (decadal, regional/continental). As such, these insights are organized into a spatial and temporal framework, which helps to clarify how feedbacks within and among these different scales create opportunities for intervention. Our key finding is that green water management at the landscape-scale constitutes the best entry point for providing leverage at both smaller and larger scales, in terms of time, space, and policy. We conclude by highlighting the urgent need for much more resilient, cross-scale green water systems that can accommodate the impending, nonstationary changes related to climate change. This urgency is further underlined by the very short time horizon for achieving the SDGs by 2030.

In agriculture sector, the effect of climate change seems to have become inevitable during the last few decades. Hence, the technologies for climate-resilient agriculture (CRA) are probably the best adaptation solutions currently available to improve the resilience of agriculture. The study to access the extent of adoption of CRA technologies by the farmers in the National Innovations in Climate Resilient Agriculture (NICRA) project implemented villages of Suryapet and Khammam districts in Telangana state was conducted during 2021-22. Total 200 farmers from these two districts were selected randomly to evaluate the adoption status of recommended CRA technologies and its association with the respondents’ profile characteristics. The respondents had adopted CRA technologies at medium to high levels with the majority of beneficiaries adopting technologies like deep ploughing, in-situ moisture conservation technologies in cotton and red gram, crop diversification from paddy to jowar and vegetables as a contingent crop, improved variety of paddy Siddhi WGL-44 and improved backyard poultry breeds. The profile characteristics viz., education, annual income, land holding, individual and mass media exposure, economic motivation, risk-taking ability, and innovative proneness had a positive and significant association with the extent of adoption of CRA technologies.
