Sustainable Land Management In The Tropics

Bringing together case studies from Kenya, Benin, Cameroon and the Philippines, this volume provides a multidisciplinary overview of the economics of natural resource management in Tropical regions, at household and village level. By comparing a wide array of climatic and economic conditions, it examines the effect of location and access to the market - as well as the importance of national policies - have on soil and water conservation. The book not only analyzes the benefits of soil and water conservation based on econometric studies, but also assesses the costs involved. In doing so it challenges commonly held assumptions about poorer community's ability to finance such measures.

Rainforests are rapidly being cleared in the humid tropics to keep pace with food demands, economic needs, and population growth. Without proper management, these forests and other natural resources will be seriously depleted within the next 50 years. Sustainable Agriculture and the Environment in the Humid Tropics provides critically needed direction for developing strategies that both mitigate land degradation, deforestation, and biological resource losses and help the economic status of tropical countries through promotion of sustainable agricultural practices. The book includes: A practical discussion of 12 major land use options for boosting food production and enhancing local economies while protecting the natural resource base. Recommendations for developing technologies needed for sustainable agriculture. A strategy for changing policies that discourage conserving and managing natural resources and biodiversity. Detailed reports on agriculture and deforestation in seven tropical countries.

Policies promoting pro-poor agricultural growth are the key to helping countries achieve the Millennium Development Goals especially the goal of halving poverty and hunger by 2015. The public sector, private sector, and civil society organizations are working to enhance productivity and competitiveness of the agricultural sector to reduce rural poverty and sustain the natural resource base. The pathways involve participation by rural communities, science and technology, knowledge generation and further learning, capacity enhancement, and institution building. Sustainable land management (SLM) an essential component of such policies will help to ensure the productivity of agriculture, forestry, fisheries, and hydrology. SLM will also support a range of ecosystem services on which agriculture depends. The 'Sustainable Land Management Sourcebook' provides a knowledge repository of tested practices and innovative resource management approaches that are currently being tested. The diverse menu of options represents the current state of the art of good land management practices. Section one identifies the need and scope for SLM and food production in relation to cross-sector issues such as freshwater and forest resources, regional climate and air quality, and interactions with biodiversity conservation and increasingly valuable ecosystem services. Section two categorizes the diversity of land management systems globally and the strategies for improving household livelihoods in each system type. Section three presents a range of investment notes that summarize good practice, as well as innovative activity profiles that highlight design of successful or innovative investments. Section four identifies easy-to-access, Web-based resources relevant for land and natural resource managers. The 'Sourcebook' is a living document that will be periodically updated and expanded as new material and findings become available on good land management practices. This book will be of interest to project managers and practitioners working to enhance land and natural resource management in developing countries.

In the tropics most of the steepland areas are settled by small-scale farming families where livelihoods may be endangered by land degradation and associated loss of productivity. This bulletin brings concepts and principles of good land husbandry into focus.

Land is the integrating component of all livelihoods depending on farm, forest, rangeland, or water (rivers, lakes, coastal marine) habitats. Due to varying political, social, and economic factors, the heavy use of natural resources to supply a rapidly growing global population and economy has resulted in the unintended mismanagement and degradation of land and ecosystems. 'Sustainable Land Management' provides strategic focus to the implementation of sustainable land management (SLM) components of the World Bank's development strategies. SLM is a knowledge-based procedure that integrates land, water, biodiversity, and environmental management to meet rising food and fiber demands while sustaining livelihoods and the environment. This book, aimed at policy makers, project managers, and development organization, articulates priorities for investment in SLM and natural resource management and identifies the policy, institutional, and incentive reform options that will accelerate the adoption of SLM productivity improvements and pro-poor growth.
