Wild foods and other nonfood NTFPs are important for improving food security and supplementing incomes in rural peoples' livelihoods. However, studies on the importance of NTFPs to rural communities are often limited to a few select sites and are conducted in areas that are already known to have high rates of NTFP use. To address this, we examined the role of geographic and household level variables in determining whether a household would report collecting wild foods and other nonfood NTFP across 25 agro-ecological landscapes in Tanzania, Rwanda, Uganda and Ghana. The aim of this study was to contribute to the literature on NTFP collection in Africa and to better understand where people depend on these resources by drawing on a broad range of sites that were highly variable in geographic characteristics as well as rates of NTFP collection to provide a better understanding of the determinants of NTFP collection. We found that geographic factors, such as the presence of forests, non-forest natural areas like grasslands and shrublands, and lower population density significantly predict whether a household will report collecting NTFP, and that these factors have greater explanatory power than household characteristics

地理因素预测四个非洲国家家庭的野生食品和非食品 NTFP 收集情况


野生食品和其他非食品非粮食产品对于改善粮食安全和补充农村人民的生计具有重要意义。然而，关于 NTFP 对农村社区重要性的研究通常仅限于少数选定的地点，并且是在已知 NTFP 使用率较高的地区进行的。为了解决这个问题，我们研究了地理和家庭层面变量的作用，以确定一个家庭是否会报告在坦桑尼亚、卢旺达、乌干达和加纳的 25 个农业生态景观中收集野生食物和其他非食物 NTFP。本研究的目的是为非洲 NTFP 收集的文献做出贡献，并通过利用地理特征和 NTFP 收集率差异很大的广泛地点，更好地了解人们在哪里依赖这些资源，以提供更好地了解 NTFP 收集的决定因素。我们发现，地理因素，例如森林、草原和灌木丛等非森林自然区域的存在以及较低的人口密度，可以显着预测家庭是否会报告收集 NTFP，并且这些因素比家庭特征具有更大的解释力
