野生食物占世界各地家庭食物消费的很大一部分，但土地利用的快速变化影响了野生食物的供应，这对小农的食物和营养摄入产生了影响。随着热带森林地区商业农业和生物多样性保护工作的增加，许多轮作耕作系统正在加强，其范围受到限制。研究这种压力的后果通常忽略了野生食物的作用日益减少。采用收集日记、参与观察、遥感和访谈相结合的方法，我们研究了老挝北部快速转变的耕作社区中农业-森林景观在提供野生食物方面的作用。我们发现，在商业农业和保护工作对土地的压力更大的地区，野生食物对人类饮食的贡献更小。我们的研究结果表明，不断增加的土地压力造成了不断变化的耕作景观和人们对其的利用的变化，对营养质量产生了负面影响，包括蛋白质缺乏，特别是在核心保护区附近的社区。我们的研究表明，在商业农业与生物多样性保护（以及促进它们的政策）、野生食物供应和粮食安全之间的联系中，采取更加营养敏感的方法是非常重要的。(C) 2016年作者。Elsevier B.V.出版
Wild food constitutes a substantial part of household food consumption around the world, but rapid land use changes influence the availability of wild foods, which has implications for smallholders' food and nutrient intake. With increasing commercial agriculture and biodiversity conservation efforts in forested tropical regions, many shifting cultivation systems are being intensified and their extent restricted. Studies examining the consequences of such pressures commonly overlook the diminishing role of wild food. Using a combination of collection diaries, participant observation, remote sensing, and interviews, we examined the role of agriculture-forest landscapes in the provision of wild food in rapidly transforming shifting cultivation communities in northern Laos. We found that wild food contributed less to human diets in areas where pressure on land from commercial agriculture and conservation efforts was more intense. Our results demonstrate that increasing pressure on land creates changes in the shifting cultivation landscape and people's use thereof with negative effects on the quality of nutrition, including protein deficiency, especially in communities adjacent to core conservation areas. Our study shows the importance of adopting a more nutrition-sensitive approach to the linkages between commercial agriculture and biodiversity conservation (and the policies that promote them), wild food provisioning, and food security.
