Book Description
Aquatic agricultural systems (AAS) are food production systems in which the productivity of freshwater or coastal ecosystems contributes significantly to total household nutrition, food security, and income in developing countries. The Consultative Group of International Agricultural Research (CGIAR) engages in research in development to address this challenge. The goal of the CGIAR research program on Aquatic Agricultural Systems (referred to in this paper as “the AAS program”) is to harness the development potential of aquatic agricultural systems to improve the livelihood security and well-being of an estimated 10 million by 2016 poor people who are dependent on these systems This working paper draws lessons from the target countries through a review of productivity interventions such as modifying habitats, harnessing underutilized productive resources, improving the integration of production commodities, supporting community-based natural resource management, and genetically improving strains. In total, this paper reviewed 20 productivity interventions.

Book Description
Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

Book Description
Due to climate change and increasing food prices, emphasis needs to be placed on addressing water management as a key determinant for agricultural production and productivity. However, governments and donors have tended to pay relatively little attention to this area, and investments remain low. This report, which is based on economic and sector work carried out in the Water Anchor of the World Bank, highlights the importance of improving water management in rainfed agriculture, with a focus on those production systems where water is a main constraint. It provides a synthesis of the state-of-the-art thinking and experience. Considering the various issues that are currently preventing further upscaling of these measures, and better evaluation of the feasibility of applying particular measures or combination of measures, the report proposes options and recommendations for interventions to help overcome these issues. In doing so, the report aims to stimulate discussion and encourage new thinking among World Bank staff and counterparts in client countries who work on enhancing agricultural productivity and livelihoods in rainfed agriculture through improved water management and related interventions.

Book Description
The CGIAR Research Program on Aquatic Agricultural Systems (AAS) is being implemented in ten communities in the Barotse floodplain of Zambia’s Western Province. With a focus on the rural poor and vulnerable, the AAS program aims to reduce poverty and improve food security by harnessing the development potential, productivity and diversity of aquatic and agricultural systems. The development challenge in the Barotse floodplain, as identified by relevant stakeholders, is to make effective use of seasonal flooding patterns and natural resources through more productive and diversified aquatic agricultural management practices that improve the lives and livelihoods of the poor and vulnerable. Food and nutrition are essential to support the overall AAS program objective and overcome the specific development challenge of the Barotse floodplain. Zambia has very high malnutrition rates, particularly for stunting in children under five. Poor nutritional status, especially of women and children, inhibits individual growth and development, and negatively impacts the overall health, productivity and economic potential of a community. The purpose of this report is to analyze the food and nutrition security situation within the Barotse floodplain. It explores multiple sectors, including nutrition, agriculture, health, and gender, at the national, provincial and community level to provide a comprehensive understanding of food and nutrition in the ten AAS communities in relation to the country as a whole. The analysis will provide informative inputs to the AAS Barotse hub design process to develop an appropriate food and nutrition research-in-development agenda.

Book Description
This technical document contains clear and practical guidelines on how to implement real water savings in agriculture through interventions for enhancing crop water productivity. A distinction is made between real water savings and “apparent” water savings. Apparent water savings record reductions in water withdrawals but do not account for changes in water consumption. Real water savings record reductions in water consumption and non-recoverable return flows (runoff or percolation). This guidance document emphasizes the paradox of water savings at field and basin scales, which usually do not translate into increased water availability for other users, as is commonly believed.

Book Description
Sustainable intensification has recently been developed and adopted as a key concept and driver for research and policy in sustainable agriculture. It includes ecological, economic and social dimensions, where food and nutrition security, gender and equity are crucial components. This book describes different aspects of systems research in agriculture in its broadest sense, where the focus is moved from farming systems to livelihoods systems and institutional innovation. Much of the work represents outputs of the three CGIAR Research Programs on Integrated Systems for the Humid Tropics, Aquatic Agricultural Systems and Dryland Systems. The chapters are based around four themes: the conceptual underpinnings of systems research; sustainable intensification in practice; integrating nutrition, gender and equity in research for improved livelihoods; and systems and institutional innovation. While most of the case studies are from countries and agro-ecological zones in Africa, there are also some from Latin America, Southeast Asia and the Pacific.
