Ethiopia, Policies for Sustainable Land Management in the Ethiopian Highlands Dataset 1998-2000

The main objective of the project was to assess policy, institutional and technological strategies to promote more productive and sustainable land management in the environmentally degraded highlands of Ethiopia. Primary cross-sectional data was collected at community, household and plot levels in the highlands of Tigray beginning in late 1998, and the highlands of Amhara beginning in late 1999, covering 500 and 434 households, respectively. The household survey includes informatio n on household endowments, land, labor, education, livestock and other assets; access to factors of production and credit, income sources, and livelihood strategies. The plot level survey contains information on plot level factors including plot quality characteristics (soil type, slope, size), land tenure, land investments, land management practices, inputs used (fertilizers, seeds, herbicides, insecticides), yields, and erosion indicators. The community survey covers topics on market access, population, irrigation programs and organizations; local prices of crops, livestock and livestock products; community natural resource management, land use and land tenure.

本项目的核心目标为评估旨在推动埃塞俄比亚生态退化高地地区实现更具生产力与可持续性土地管理的政策、制度与技术策略。研究于1998年末率先在提格雷（Tigray）高地启动，1999年末拓展至阿姆哈拉（Amhara）高地；所采集的一手横截面数据（cross-sectional data）覆盖社区、家庭与地块三个层级，分别纳入500户与434户受访家庭。家庭调研问卷涵盖家庭禀赋、土地、劳动力、教育、牲畜及其他资产状况，生产要素获取、信贷可及性、收入来源与生计策略等相关信息。地块层级调研包含地块层面的多项特征：具体包括土壤类型、坡度、面积等地块质量属性，土地权属、土地投资、土地管理实践，化肥、种子、除草剂、杀虫剂等投入品使用情况，作物产量及侵蚀状况指标等。社区调研则覆盖市场准入、人口规模、灌溉项目与组织架构，农作物、牲畜及畜牧产品的本地价格，社区自然资源管理、土地利用及土地权属等议题。
