Book Description
In many regions of the world, sustainable and reliable delivery of water services has become increasingly complex and problematic. Complexities that are very likely to increase, considering the unprecedented confluence of pressures linked to demographic, economic, dietary trends, and climate change. Particularly if overall demand for freshwater exceeds supply, the delivery of water services is often less about engineering, although engineering is still required, and more about politics, governa nce, managing and protecting sources, resolving conflicts about water, ensuring rights to water are respected, and so on. It is also about understanding and monitoring the hydrological cycle at the appropriate scale of analysis. This is where water accounting and auditing can play a crucial role. The rationale behind this water accounting and auditing sourcebook is that scope exists worldwide to improve water-related sectoral and inter-sectoral decision-making at local, regional and national le vels. Water accounting and auditing are recommended by FAO and others as being fundamental to initiatives that aim to cope with water scarcity. This sourcebook aims to provide practical advice on the application and use of water accounting and auditing, helping users planning and implementing processes that best fit their needs.

Book Description
A survey of 76 public smallholder irrigation schemes in the Limpopo Province was jointly conducted by the International Water Management Institute (IWMI), Department of Agriculture, Forestry and Fisheries (DAFF), South Africa, and the Limpopo Department of Agriculture and Rural Development (LDARD), as part of the ‘Revitalization of Smallholder Irrigation in South Africa’ project. About one-third of those schemes was fully utilized; one-third partially utilized; and one-third not utilized in the winter of 2015; however, no single socioeconomic, physical, agronomic and marketing variable could explain these differences in utilization. Sale, mostly for informal markets, appeared the most important goal. Dilapidated infrastructure was the most important constraint cited by the farmers. The study recommends ways to overcome the build-neglect-rebuild syndrome, and to learn lessons from informal irrigation, which covers an area three to four times as large as public irrigation schemes in the province.

Book Description
Water cooperation has received prominent focus in the post-2015 United Nations Sustainable Development Goals (SDGs). While proposals for measuring water cooperation appear to be converging toward a small set of indicators, the degree to which these proposed indicators draw on past work is unclear. This paper mines relevant past work to generate guidance for monitoring the proposed SDG target related to transboundary water cooperation. Potential measures of water cooperation were identified, filtered and applied in three countries (Botswana, South Africa and Zimbabwe). Six indicators were ultimately determined as being suitable for measuring water cooperation. As the SDG process turns its focus to the selection of indicators, the indicators proposed in this paper may merit consideration

Book Description
Springs are the major source of freshwater in many small mountainous watersheds within the Himalayan region. In recent years, their flow rates have diminished, but the reasons for this are not self-evident, and hence this paper reviews the methods to investigate Himalayan springs. The review reveals that chemical and isotope analyses – mostly water dating and stable isotope (e.g., d18O) analyses – could be an appropriate entry point to commence field investigations, because of their potential to map complex spring pathways, including linkages between aquifers. This should be combined with the building of hydrogeological maps with the available data. Output from desktop analyses, field investigations and hydrogeological maps could then contribute to the establishment of a conceptual model, which could form the basis for a numerical model.

Book Description
Sustainable participatory watershed management is an approach promoted by the Ethiopian government to restore natural resources and agricultural productivity across the country. This comparative study between six watershed programs shows that this approach increases farmers’ food security and incomes (around 50% on average), as well as their resilience to drought and other climate shocks. However, the study also confirms that the nature and scale of impact can vary significantly between watershed programs. The success of watershed management depends on multiple factors from the hydrological profile of the watershed to the local social and economic environment. Tailoring watershed interventions to the local context, associating conservation and livelihoods activities, and providing further financial and technical support to watershed committees are among the recommendations of this paper.
