Thanks to farmers’ resistance to provide land for constructing watercourses below the outlets, India’s famous Sardar Sarovar Project is stuck in an impasse. Against a potential to serve 1.8 million hectares, the Project was irrigating just 100,000 hectares five years after the dam and main canals were ready. Indications are that full project benefits will get delayed by years, even decades. In this paper, IWMI researchers advance ten reasons why the Project should abandon its original plan of constructing open channels and license private service providers to invest in pumps and buried pipeline networks to sell irrigation service to farmers.

Agriculture is the most significant contributor to Ethiopia’s economy. Most of the agricultural production is under rainfed conditions and thus extremely sensitive to rainfall variability. Irrigation development, including smallholder irrigation, is used by the Ethiopian Government to attempt to mitigate the effects of rainfall variability. In this study, we look at smallholder irrigation – modern and traditional irrigation systems. A detailed description of the cropping patterns is given. The stochastic frontier production function approach is used to estimate technical inefficiency, and constraints to production are analyzed. Since the traditional system is found to be efficient but on a lower production frontier, the study shows that significant gains can be made by raising the frontier of the traditional systems and increasing the efficiency of the modern systems. Among the production constraints studied were land preparation, soil fertility, weed control, pests and diseases, soil erosion, input access and moisture deficiency. The most significant constraints on the irrigated systems were input access and moisture deficiency.

this book contains additional research papers submitted for a meeting on sustainable development and planning organized in 2011 by the Wessex Institute of Technology (WIT). WIT has a long and very successful record of organizing conferences on the topic of sustainability, which requires an interdisciplinary approach. Any sustainable solutions that are derived solely from the perspective of a single discipline may have unintended damaging consequences that create new problems.Thus effective sustainable solutions require the collaboration of scientists and engineers from various disciplines, as well as planners, architects, environmentalists, policy makers, and economics. These experts must not only communicate with each other effectively, but also understand the social aspects of the problem at hand. The contents of the book reflect that interdisciplinary approach.The topics covered by the papers in the book include: City Planning, Regional Planning; Social and Political Issues; Sustainability in the Built Environment; Rural Development; Cultural Heritage; Transportation; Ecosystems Analysis; Protection and Remediation; Environmental Management; Environmental Impact Assessment; Indicators of Sustainability; Sustainable Solutions in Developing Countries; Sustainable Tourism ; Waste Management; Flood Risk Management; Resources Management; Industrial Developments.

Interest in African irrigation investment is growing. However, irrigation is not a monolithic concept, and the opportunities and risks can vary substantially by approach. To help provide an understanding of the variation, this paper builds on previous work to provide a detailed typology of irrigation systems as currently used in Ghana.

The Niger River Basin covers 7.5% of the African continent and is shared between nine riparian countries. The human population of the basin is growing at an average annual rate of about 3%, which makes the Niger River Basin one of the areas with the highest fertility rates in the world. The desert margin is expanding; climate change is negatively impacting rainfall; and urbanization, industrialization, and the human and livestock population are threatening the quantity and quality of available water resources. The basin population already suffers from chronic poverty. Based on a literature review, this paper suggests some key water-related and other interventions that are capable of easing the basin’s development challenges.

The AgWater Solutions Project, carried out between 2009 and 2012, focused on resolving water issues faced by smallholder farmers. The project examined existing Agricultural Water Management (AWM) solutions, together with factors that influence their adoption and scaling up. The project aimed to identify investment opportunities in AWM that have high potential to improve the incomes and food security of poor farmers. The work was undertaken in the African countries of Burkina Faso, Ethiopia, Ghana, Tanzania and Zambia, and in the Indian States of Madhya Pradesh and West Bengal. This Working Paper series summarizes results and recommendations from the research carried out in each of these countries and states.
