在获得外部投入有限的地区，豆类是以生态为基础的集约化解决办法的一部分。尽管进行了几十年的干预，但撒哈拉以南非洲的小农农业系统对豆类的吸收仍然缓慢。我们通过对肯尼亚和刚果民主共和国的小规模农户进行定制调查，制定了一个家庭豆类种植指标（HLC），探讨了豆类种植背后的驱动因素。一个贝塔回归框架确定的范围内的强度跨网站和农场，表明农业生态区和正式机构的影响有限的吸收。年龄、收入和性别具有积极但非常边际的影响。密集豆类种植较少受到商业增长目标或获得市场机会的驱动，这表明缺乏豆类市场来激励生产。人们对扩大农场面积兴趣不大，这反映了这些农民缺乏可用的资产，并导致使用豆类提供家庭营养，或支持农场生育和牲畜饲料。通过在各区域收集一致的数据，或至少对豆类吸收进行同样详细的研究，将能够进一步发展这一HLC指标。
Legumes form part of an ecological-based solution to intensification in areas with limited access to external inputs. Despite a number of decades of intervention, uptake of legumes has been slow within smallholder farming systems in sub-Saharan Africa. We explore the drivers behind the adoption of legumes by developing an indicator of household legume cultivation (HLC) from a bespoke survey of small-scale farm households in Kenya and the Democratic Republic of the Congo. A beta regression framework identifies the range of intensities across sites and farms, indicating a limited influence of agro-ecological zones and formal institutions on uptake. Age, income and gender have positive but very marginal effects. Intensive legume cultivations were less driven by commercial growth objectives or access to market oppourtunities indicating lack of legume markets to incentivize production. There was little interest in expanding farm area, which reflects the lack of assets available to these farmers and leads to the use of legumes for providing home nutrition, or supporting farm fertility and livestock feed. Further development of this HLC metric would be enabled by consistent data gathering across regions, or at least equally detailed studies of legume uptake.
