Описание: Integrated Landscape Approaches for Africa's Drylands presents emerging fi ndings on the importance of moving beyond single-sector interventions to embrace integrated landscape management that takes into account the health of the ecosystems that support human livelihoods and contribute to the resilience of rural communities in Sub-Saharan African drylands. Integrated landscape management is particularly important for these drylands because people depend on production systems that are frequently disrupted by exogenous shocks such as drought. The ecological and economic evidence presented in this book shows that integrated landscape management can enhance efforts to invest in tree-based systems and improved livestock management and support productivity increases for rain-fed cropping. Integrated landscape management efforts have helped to coordinate the actions of multiple land users and other stakeholders, reduced confl icts, and improved overall governance of water, land, and other resources. Integrated landscape management is thus a useful approach to enhance the intensifi cation of dryland cropping systems and will, in many locations (but not always), result in multiple wins-- including improved farm productivity, water benefi ts at the farm and landscape levels, carbon sequestration, biodiversity and other ecosystem services benefi ts, and higher climate resilience. Various policies and related interventions can be used to trigger and accelerate the scaling up of these benefi ts through integrated landscape management across Sub-Saharan African drylands to restore and increase household and ecological resilience. Policies are needed to develop the framework conditions necessary to both initiate new programs and modify and scale up existing restoration and resilience efforts. The book highlights policy options, covering six broad intervention areas: (1) Clarify land rights and responsibilities; (2) Encourage multistakeholder involvement and collective action; (3) Overcome institutional barriers to integrated landscape management; (4) Create conditions for adaptive planning and management; (5) Create mechanisms and supporting policies for sustainable and long-term fi nancing of integrated landscape management; and (6) Invest in a solid evidence base and knowledge-sharing platforms for integrated landscape management.

Описание: Tree-based production systems have enormous potential to reduce vulnerability and increase the resilience of households living in dryland regions of Sub-Saharan Africa. Trees are key providers of biomass, which is critical for many livelihood needs. Wood from trees is the leading source of energy in many dryland countries and is an important construction material. Foliage and pods from trees and shrubs are the most important source of feed for camels and goats, which are the dominant livestock species in the more arid parts of the drylands. Trees and shrubs offer enhanced sources of the organic matter needed to improve the structure and raise the fertility of soils used for agriculture. Many parts of trees provide different medicinal products for people. And fruits and vegetable foliage harvested from trees are important seasonal food sources for people living in drylands, and for sale. The benefits from trees take on added value when one considers that they are relatively impervious to many of the shocks that affect other production systems, especially livestock keeping and agriculture. Trees, with their deep rooting systems, maintain their standing value and offer some production even in drought years. They are therefore a good buffer against climatic risk and are a critical element in a diversification strategy designed to maintain levels of consumption and income in good times and bad. In addition, their value can be tapped when it is most needed: wood from trees can be harvested throughout the year, and many annual tree products are harvested at times different from the times when annual crops are harvested. 'Tree-Based Production Systems for Africa's Drylands' identifies some of the most promising investment opportunities at the level of tree-based systems, species (products), and well-defined management practices for accelerating rural economic growth in the drylands.

Описание: Social Protection Programs for Africa's Drylands explores the role of social protection in promoting the well-being and prosperity of people living in dryland regions of Sub-Saharan Africa, with a specifi c focus on the Sahel and the Horn of Africa. Based on a review of recent experience, it argues that social protection policies and programs have an important role in promoting the resilience of the people residing in these areas. Social protection programs, when well designed and carefully implemented at scale, can reduce vulnerability to droughts and other shocks and promote coping capacity. If present trends continue, by 2030 dryland regions of East and West Africa will be home to an estimated 429 million people, up to 24 percent of whom will be living in chronic poverty. Many others will depend on livelihood strategies that are sensitive to the shocks that will hit the region with increasing frequency and severity, making them vulnerable to falling into transient poverty. Social protection programs will be needed in the drylands to provide support to those unable to meet their basic needs. Some of these people will require long-term support, while others will require periodic short-term support because of income losses due to shocks (for example, crop failure following a drought) or as a result of lifecycle changes (for example, loss of a breadwinner). Safety net programs can increase resilience in the short term by improving coping capacity of vulnerable households. Rapidly scalable safety nets that provide cash, food, or other resources to shock-affected households can allow them to recover from unexpected shocks. Scaling up an existing safety net program can be far less expensive than relying on appeals for humanitarian assistance to meet urgent needs. Social protection programs can increase resilience over the longer term by reducing sensitivity to shocks of vulnerable households especially if combined with other development programs. Providing predictable support to chronically poor households and enabling them to invest in productive assets and access basic social services can effectively reduce these households' sensitivity to future shocks, help them participate in the growth process, and take advantage of the investments made in agricultural and pastoralist activities proposed in the drylands.
Описание: Drylands account for three-quarters of Sub-Saharan Africa's cropland, two-thirds of cereal production, and four-fifths of livestock holdings. Today frequent and severe shocks, especially droughts, limit the livelihood opportunities available to millions of households and undermine efforts to eradicate poverty in the drylands. Prospects for sustainable development of drylands are assessed in this book through the lens of resilience, understood here to mean the ability of people to withstand and respond to droughts and other shocks. An original model was developed expressly to consistently and coherently evaluate different type of interventions on the ground, which provided a common framework to anticipate the scale of the challenges likely to arise in drylands, as well as to generate insights into opportunities for addressing those challenges.Such modelling framework consisted in a) estimating the baseline vulnerability profiles of people living in drylands (2010), b) estimate the evolution of vulnerability by 2030 under a range of assumptions, c) calculated the number of people affected by drought in the different administrative units of each country, and d) evaluate different types of interventions in agriculture and livestock for mitigating drought impact by calculating the potential for reducing the number of people affected for each scenario and conducting a simplified · benefit/cost (B/C) analysis for each type of intervention.For livestock, simulation models were used to estimate the impacts of feed balances, livestock production, and household income resilience interventions under different climate scenarios). For agriculture, the DSSAT (Decision Support System for Agrotechnology Transfer) framework was used to assess the potential impact on yields likely to result from adoption of five crop farming technologies: (1) drought-tolerant varieties, (2) heat-tolerant varieties, (3) additional fertilizer, (4) agroforestry practices, (S) irrigation (6) water-harvesting techniques and selected combinations thereof.

Описание: Prospects for Livestock-Based Livelihoods in Africa's Drylands examines the challenges and opportunities facing the livestock sector and the people who depend on livestock in the dryland regions of Sub-Saharan Africa. It presents a novel way of thinking about pastoral development, grounded in a conceptual framework that focuses on the multiple shocks that drylands livestock keepers face and how those shocks can be addressed, drawing on a state-of-the-art literature review carried out by scientists of leading research institutes and development organizations, and integrating the results of an innovative approach to modeling development options for the drylands livestock sector. Looking to the future, the picture is mixed. On the positive side, demand for red meat is expected to strengthen in domestic and regional markets, suggesting that livestock keepers will have good market opportunities. On the negative side, a large majority of livestock keepers are classifi ed as poor, and the natural (feed) resource base is likely to be suffi cient to enable improved meat and milk production for the growing human population. Prospects for the livestock sector through 2030 vary by aridity zone. In arid and semi-arid zones, a reasonable goal for 2030 is to have land use, training, and microfi nance systems established that promote an appropriate balance between human and livestock carrying capacities, featuring mainly grassland/pastoral systems that reliably and sustainably satisfy the minimum income needs of herder households, produce at least a signifi cant part of the demand in local markets for animal source food, and provide environmental services for which livestock keepers receive compensation. The goal includes signifi cant employment generation outside the sector. In the higher rainfall zones of the semi-arid areas, and in the subhumid zones, a reasonable goal for 2030 is to have intensifi ed production systems established, featuring mainly mixed livestock/arable farming or agro-pastoral systems that are closely linked to nearby grassland/pastoral systems and that consistently generate marketable surpluses of differentiated red meat and livestock products that can compete not only in the expanding domestic market but also in selected regional markets.

Описание: Drylands in East Asia (DEA)are home to more than one billion people with an environment vulnerable to natural and anthropogenic changes. One of the critical needs in the region is to fully understand how dryland ecosystems respond to the changing climate and human activities in order to develop strategies to cope with continued climate change. This book provides state-of-the-art knowledge and information on drylands ecosystem dynamics, changing climate, society, and land use in the region. In addition to the synthesis of the existing research and knowledge of DEA, the book provides a role model for regional ecological assessment. With a wide spectrum of contributions from experts around the globe, the book should be of interest to researchers and students both internationally and in East Asia. Lessons learned from this synthesis effort in DEA should be useful for developing climate adaptation strategies for other similar regions around the globe.
