Rwanda High Iron Bean (HIB) Impact Assessment Survey

An impact assessment (IA) study was conducted in Rwanda in 2015 to determine the adoption and diffusion rates of high iron beans (HIB) varieties after eight seasons of active dissemination; understand HIB adoption and diffusion patterns across varieties and over time (the percentage of farmers currently planting, the percentage rate of addition, the percentage rate of dropout, the percentage of bean area currently under HIB, and so forth); and assess the socioeconomic and nutrition impacts resulting from HIB adoption. A nationally representative listing exercise preceded the main household survey for the impact assessment. The listing exercise was conducted across 120 rural villages in 29 provinces of Rwanda and was administered to a total of 19,575 households. The data included here are from both the listing exercise and the main impact assessment survey.

本研究于2015年在卢旺达开展了一项影响评估（Impact Assessment, IA），旨在明确经过8个种植季的主动推广后，高铁豆（High Iron Beans, HIB）品种的采用率与推广扩散速率；解析不同品种及时间维度下的高铁豆采用与扩散模式，涵盖当前种植农户占比、新增采用农户占比、退出采用农户占比、当前种植高铁豆的豆田面积占比等指标；并评估采用高铁豆所带来的社会经济与营养健康影响。本次影响评估的正式家庭入户调查开展前，先实施了一项全国代表性的农户清单编制工作。该清单编制工作覆盖卢旺达29个省份的120个乡村，共完成19575户家庭的调研。本文所附数据集同时包含该农户清单编制工作与本次影响评估正式调查的相关数据。
