Book Description
The present study explores the application of the Gini Coefficient, which has hitherto only been used for income and land distribution, to quantify the distribution of water resources. The tool is tested in the water-stressed Olifants Water Management Area, in South Africa. Using readily available information on water use registrations, water use estimates, and census data, two versions of the Gini Coefficient are calculated. The first measures the distribution of the allocation of direct water use in rural areas and was estimated at 0.96 in the study area. In other words, 99.5 percent of the rural households are entitled to useonly 5 percent of the available water. The second version calculates the distribution of the indirect benefits of water use in the form of direct employment. This is shown to have a Gini Coefficient of 0.64. Using the Gini Coefficient an assessment was also made of the impacts of different policy scenarios. It was found that by more than doubling the amount of water used by rural households from the current 225 cubic meters per household per annum (m3/hh/annum) to 610 m3/hh/annum, which would enable each household to meet its basic human needs of 50 litres/person/day and irrigate 1,000 square meters (m2), would reduce the Gini Coefficient significantly. Yet, this would only require the large-scale registered users to reduce their current irrigation water use entitlement by 6 percent or the largest ten users to reduce their use by 20 percent each.

Book Description
Since the start of the twenty-first century there has been an unprecedented focus upon water as a key factor in the future of both society and environment. Water management lies at the heart of strategies of development as does the added the hazard of climate change. Water Resources and Development provides a stimulating interdisciplinary introduction to the role of water resources in shaping opportunities and constraints for development. The book begins by charting the evolution of approaches to water management. It identifies an emerging polarization in the late twentieth century between ‘technical’ and ‘social’ strategies. In the past decade these two axes of policy debate have been further intersected by discussion of the scale at which management decisions should be made: the relative effectiveness of ‘global’ and ‘local’ governance of water. A variety of case studies elaborate this analytical framework, exemplifying four key development challenges: economic growth, poverty reduction, competition and conflict over water, and adaptation to climate change. Current ‘best practice’ for water management is examined, addressing strategies of water supply augmentation, the ecological implications of intensified use, and strategies of demand management guided by economic or political principles. It is argued defining ‘successful’ water management and best practice requires first the establishment of development goals and the implicit trade-offs between water consumption and conservation. This engaging and insightful text offers a unique interdisciplinary analysis by integrating scientific, engineering, social and political perspectives. This is an essential text for courses on development studies, geography, earth sciences and the environment.

Book Description
Water resource development has played a significant role in the expansion of agriculture and industry in the Olifants River Catchment. However, currently water deficit is one of the major constraints hampering development in the catchment; both the mining and agricultural sectors are producing below optimal levels because of their reliance on insufficient supplies. In this study, the Water Evaluation and Planning (WEAP) model was used to evaluate scenarios of historic, current and future water demand in the catchment. For each scenario, the WEAP model was used to simulate demand in five different sectors (rural, urban, mining, commercial forestry and irrigation) over a 70-year period of varying rainfall and hydrology. Levels of assured supply were estimated for each sector and the economic cost of failing to provide water was predicted. For the future scenarios, the impact of infrastructure development and water conservation measures were assessed. The study illustrates how a relatively simple model can provide useful insight for resource planning and management.

Book Description
One of the early set of reforms that South Africa embarked on after emerging from apartheid was in the water sector, following a remarkable, consultative process. The policy and legal reforms were comprehensive and covered almost all aspects of water management including revolutionary changes in defining and allocating rights to water, radical reforms in water management and supply institutions, the introduction of the protection of environmental flows, and major shifts in charging for water use and in the provision of free basic water. Over ten years of implementation of these policy and legislative changes mean that valuable lessons have already been learned and useful experiences gained in the challenge of effective water resources management and water services provision in a middle income country.

Book Description
In the face of growing water stress and increasing concerns over the sustainability of water use, Tanzania has, in common with many other countries in Africa, focused largely on the development of more integrated catchment-wide approaches to water management. In the Great Ruaha River Basin, considerable effort has gone into increasing water productivity and the promotion of mechanisms for more efficient allocation of water resources. Over a period of five years, the RIPARWIN project investigated water management in the basin and evaluated the effectiveness of some of the mechanisms that have been introduced. The study findings are relevant to basins in developing countries where there is competition for water and irrigation is one of the main uses.

Book Description
The 'Gender in Agriculture Sourcebook' provides an up-to-date understanding of gender issues and a rich compilation of compelling evidence of good practices and lessons learned to guide practitioners in integrating gender dimensions into agricultural projects and programs. It is serves as a tool for: guidance; showcasing key principles in integrating gender into projects; stimulating the imagination of practitioners to apply lessons learned, experiences, and innovations to the design of future support and investment in the agriculture sector. The Sourcebook draws on a wide range of experience from World Bank, Food and Agriculture Organization (FAO), International Fund for Agricultural Development (IFAD), and other donor agencies, governments, institutions, and groups active in agricultural development. The Sourcebook looks at: access to and control of assets; access to markets, information and organization; and capacity to manage risk and vulnerability through a gender lens. There are 16 modules covering themes of cross-cutting importance for agriculture with strong gender dimensions (Policy, Public Administration and Governance; Agricultural Innovation and Education; Food Security; Markets; Rural Finance; Rural Infrastructure; Water; Land; Labor; Natural Resource Management; and Disaster and Post-Conflict Management) and specific subsectors in agriculture (Crops, Livestock, Forestry, and Fisheries). A separate module on Monitoring and Evaluation is included, responding to the need to track implementation and development impact. Each module contains three different sub-units: (1) A Module Overview gives a broad introduction to the topic and provides a summary of major development issues in the sector and rationale of looking at gender dimension; (2) Thematic Notes provide a brief and technically sound guide in gender integration in selected themes with lessons learned, guidelines, checklists, organizing principles, key questions, and key performance indicators; and (3) Innovative Activity Profiles describe the design and innovative features of recent and exciting projects and activities that have been implemented or are ongoing.

Book Description
This report attempts to introduce a prototype scoring system for the ecological status of rivers in India and illustrate it through the applications in several major river basins. This system forms part of the desktop environmental flow assessment and is based on a number of indicators reflecting ecological condition and sensitivity of a river. The unique aspect of this study is that it interprets, for the first time, the existing ecological information for Indian rivers in the context of environmental flow assessment. The report targets government departments, research institutions and NGOs which are engaged in environmental flow management and associated policy development, and suggests some subsequent steps in environmental flow work in India.

Book Description
This study attempts to examine those unique aspects of interbasin water transfer planning, which are of critical importance to the sustainable water resources development in India. It focuses on the crucial aspect of accurate quantification of surface water availability, which determines the entire feasibility of a water transfer. It also illustrates the impacts of upstream water resources development on the deltas’ environment thus justifying the deltas’ environmental flow requirements. The report targets government departments, research institutions and NGOs – primarily in India and other countries of the region – which are engaged or interested in issues of interbasin water transfer and environmental water management. The research intends to: contribute to the effectiveness of water resources planning and management in India; emphasize the need for urgent improvement of access to hydrometeorological data in the country; and aim to stimulate further debate on water transfers.
