Book Description
Rapidly increasing population in the dynamic semi-arid agro-ecosystems in sub-Saharan Africa (SSA) highlights the necessity to increase food production, while at the same time safe-guarding other ecological systems that support human development and well-being. In the past, increases in crop production to keep pace with population growth in this region were largely achieved through the expansion of cultivated area. Today, we must also consider ways of improving the productivity of already existing cropping systems. elopment-oriented research and describes the integrated research approach of the SSI program, its interconnected research projects - their scope and methodologies

Book Description
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.

Book Description
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.

Book Description
The challenge of water scarcity as a result of insufficient seasonal rainfall and dry spell occurrences during cropping seasons is compounded by inefficient agricultural practices by smallholder farmers where insignificant soil and water conservation efforts are applied. The hypothesis of this research is that many of the past research efforts have

Book Description
The degradation of land and water resources as a result of agricultural activity has had an enormous impact on human societies and economies. It is predicted that, by 2025, most developing countries will face physical or economic water scarcity, compounded by land degradation. In order to alleviate this problem, an advanced understanding of the state of our water resources and the relationships between land use, water management and social systems is needed. Conserving Land, Protecting Water includes an overview of global patterns of land and water degradation and discusses new insights drawn from successful case studies on reversing soil and water degradation and their impact on food and environmental security.

Book Description
For integrated water resources management both blue and green water resources in a river basin and their spatial and temporal distribution have to be considered. This is because green and blue water uses are interdependent. In sub-Saharan Africa, the upper landscapes are often dominated by rainfed and supplementary irrigated agriculture that rely on green water resources. Downstream, most blue water uses are confined to the river channels, mainly for hydropower and the environment. Over time and due to population growth and increased demands for food and energy, water use of both green and blue water has increased. This book provides a quantitative assessment of green-blue water use and their interactions. The book makes a novel contribution by developing a hydrological model that can quantify not only green but also blue water use by many smallholder farmers scattered throughout the landscape. The book provides an innovative framework for mapping ecological productivity where gross returns from water consumed in agricultural and natural vegetation are quantified. The book provides a multi-objective optimization analysis involving green and blue water users, including the environment. The book also assesses the uncertainty levels of using remote sensing data in water resource management at river basin scale.
