Ghana Household Surveys for Agricultural Biodiversity Assessment

To identify and quantify the number of all plant and animal species (domesticated and wild) and within each species, the number of types/varieties/breeds at the household-level that are: (a) grown on farm and home garden, or collected from the wild; (b) consumed as part of the diet; and (c) purchased and sold in the study sites. Information was collected for each species on its place of production or collection (farm, home garden, collected in the wild, etc.), the objective for its production or collection (Self-consumption, sale in the market, both), its different uses (food, medicine, animal feed, building material, processing, etc.), seasonality, the number of types, varieties and breeds recognized and used, key characteristics of its seed system (sources of seed, transactions and social relationships), and the water regime associated with its production (rainfed, irrigated, water harvest, etc.). Also data on assets and other socioeconomic indicators were collected. A household survey was carried out with a representative random sample of 60 households per village in three villages in the district of Lawra, (part of the Wa, Bobo and Sikasso transect where the CRP Dryland System is working in West Africa). Three villages were selected. The total sample size is 180 households.

本数据集旨在识别并量化所有驯化与野生动植物物种的总数，并针对每一物种，统计其在农户层面的类型、变种或品种数量，这些物种需满足以下三类条件：(a) 在农田与家庭菜园种植，或从野外采集；(b) 作为膳食组成部分被食用；(c) 在研究区域内进行买卖交易。针对每一物种，研究人员收集了以下信息：其生产或采集地点（农田、家庭菜园、野外采集等）、生产或采集目的（自用、市场售卖、兼具二者）、多重用途（食品、医药、动物饲料、建筑材料、加工原料等）、季节性特征、被认知与使用的类型、变种及品种数量、种子系统的关键特征（种子来源、交易行为与社会关系），以及与其生产相关的水分管理模式（雨养、灌溉、集水种植等）。此外，本数据集还收集了农户资产及其他社会经济指标相关数据。本次研究在西非拉瓦区（Lawra）下辖的3个村庄开展农户入户调查，每个村庄抽取60户具有代表性的随机样本，该区域属于瓦（Wa）、博博（Bobo）与锡卡索（Sikasso）样带，为CRP旱地系统（CRP Dryland System）在西非的工作区域之一。本次共选取3个村庄，总样本量为180户农户。
