Download or read book Water productivity the yield gap and nutrition written by Lundqvist, Jan., Malmquist, L., Dias, P., Barron, J. and Wakeyo, M. B. and published by Food & Agriculture Org.. This book was released on 2021-03-26 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report uses a nutritional water productivity (NWP) framework to interpret the relationship between nutrition and water in the context of water challenges. It argues that higher yields – of both staple and nutritious crops – are possible, even in water-stressed areas. This will require an agricultural transformation that ensures that efforts to enhance water productivity are linked to the promotion of healthy diets. Increasing water productivity and stabilizing yields at realistic levels will also be crucial to increasing the resilience of farmers. Better coordination and timing of water and other inputs, notably fertilizers and improved seeds, is likely to enhance productivity and to reduce the threats of a further encroachment of agriculture into other ecosystems. A diversified production system is required for food security, nutrition and poverty alleviation. There is an opportunity to provide strategic support for crops and other farm produce with high economic and nutritional value. A range of crops and other produce can be included in farming systems ranging from rainfed to irrigated agriculture. For the farmers to be stimulated and able to capitalize on the increasing need and demand for such produce, the development of markets, and associated investments in cold storage, roads/transport and food procurement programmes that prioritize nutritious produce will be key.

Download or read book Agricultural Water Productivity Optimization for Irrigated Teff Eragrostic Tef in a Water Scarce Semi Arid Region of Ethiopia written by YenesewMengiste Yihun and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The prospects for the future are clear. Agriculture will have to respond to changing patterns of demand for food and combat food insecurity and poverty amongst marginalized communities. In so doing, agriculture will have to compete for scarce water with other users and reduce pressure on the water environment. Moreover, water managers have to unlock the potential of agricultural water management practices to raise productivity of water, spread equitable access to water, and conserve the natural productivity of the water resource base. This PhD thesis presents field tests combined with modelling work on the cultivation of irrigated Teff (Eragrostic Tef) in the Awash Rift Valley of Ethiopia. The field experiments were conducted during the dry season for two years. The results of these studies revealed that dealing with improvement of water productivity is closely related to the irrigation practice of regulated deficit irrigation and has a direct effect on yield, as the amount of water applied decreases intentionally the crop yield drops. Overall, this research has demonstrated the potential and the limitations of combining experimental fieldwork with modelling to optimize agricultural water productivity for Teff cultivation. Focusing on only experimental fieldwork is a single approach, and is hardly ever sufficient for achieving the best solutions to current water management problems. New guidelines on using the combined effort of experimental work in the field to produce field experimental data and using models are clearly needed. It is to these needs as well as to the required increase of Teff production under water scarce conditions that this research provides its main contribution."--Provided by publisher.

Download or read book Sustainable Intensification written by Jules N. Pretty and published by Routledge. This book was released on 2012-06-25 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Handbook of Water Harvesting and Conservation written by Saeid Eslamian and published by John Wiley & Sons. This book was released on 2021-03-01 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water harvesting is gaining more and more recognition as a sustainable and resilient water supply options. It is economically viable, socially compatible and environmentally friendly. Water harvesting has proven to be a robust solution to overcome or reduce water shortages all over the world. It is important to understand how to apply this practice in a sustainable and effective way to make full use of its potential in a world increasingly threatened by water scarcity. The Handbook of Water Harvesting and Conservation: Basic Concepts and Fundamentals is the most comprehensive, up-to-date and applied handbook on water harvesting and conservation yet published. The book’s 30 chapters -- written by 84 outstanding international experts from approximately 20 selected countries faced by drought -- explore, critique and develop concepts and systems for water harvesting. The editors bring together many perspectives into a synthesis that is both academically based and practical in its potential applications. The Handbook of Water Harvesting and Conservation: Basic Concepts and Fundamentals is an important tool for education, research and technical works in the areas of soil, water and watershed management and is highly useful for drought strategy planning, flood management and developing techniques to adapt to climate change in urban, agricultural, forest and rangeland areas.
