无法获得粮食及其供应是非洲的核心关切，也是对人类福祉和经济增长的根本挑战。农业产量低导致收入低、营养不良、易受风险影响和缺乏权能。非洲发展新伙伴关系的目标是农业生产率年均增长6%，以确保粮食安全和可持续的国民经济。土地退化和土壤肥力或养分耗竭被认为是半干旱热带地区粮食安全和自然资源保护的主要威胁。现在需要的是打破非洲贫穷与土地退化之间的循环，采取在经济上增强农民权能的战略，并利用高效率、有效和负担得起的农业技术促进可持续的农业集约化。这种负担得起的管理系统应当向贫穷的小规模生产者开放，而且所采取的办法应当是全面和动态的，以便促进技术和体制变革。本文件旨在加强传播我们关于赞比亚土壤及其管理的知识库。这包括土壤保持和保护性耕作问题。主要活动是：清查缓解土地退化的现有技术，以及如何利用农民参与的办法，展示和调整适合农民情况的最佳技术;通过使用适当的工具、方法和战略，扩大可持续土地管理的最佳技术和销售办法;研究在可变环境条件下产生的生态复原力。
Lack of access to food and its availability is of central concern in Africa and a fundamental challenge for human welfare and economic growth. Low agricultural production results in low incomes, poor nutrition, vulnerability to risks and lack of empowerment. The New Partnership for Africa’s Development (NEPAD) targets an average annual increase of 6% in agricultural productivity to ensure food security and sustained national economies. Land degradation and soil fertility or nutrient depletion are considered as the major threats to food security and natural resource conservation in the semi arid tropics (SAT). What is needed is to break the cycle between poverty and land degradation in Africa by employing strategies that empower farmers economically and promoting sustainable agricultural intensification using efficient, effective and affordable agricultural technologies. Such affordable management systems should be accessible to the poor, small-scale producers and the approach should be holistic and dynamic in order to foster both technical and institutional change. This paper aims to increase the dissemination of our knowledge base on soils and its management in Zambia. This includes issues of soil conservation and conservation farming. The main activities being to: inventories available technologies for alleviating land degradation and how to demonstrate and adapt the best-bets in farmers’ circumstances using farmer participatory approaches; scale up best bet technologies for sustainable land management and marketing options through the use of appropriate tools, methods and strategies; and to study the resulting ecological resilience under variable environmental conditions.
