Conservation agriculture (CA) is a management paradigm in which soil is covered outside of cropping seasons, minimally disturbed, and recharged with nitrogen-fixing legumes. Finding effective ways to encourage CA is a centuries-old problem playing out acutely today in Sub-Saharan Africa. To better understand this issue, we have collected data on rural livelihoods and CA adoption during a two-year intervention in southern Malawi. The intervention evaluated rates of CA adoption under two different structures of payment and three levels of monitoring. The dataset includes a baseline and endline survey covering 1,900 households, along with surveys conducted with participants opting into the intervention. Baseline and endline questions included modules on farm-level inputs and production at the plot-crop level; plot characteristics; household composition and assets; savings, loans, and other sources of income; neighborhood characteristics; and perceptions regarding CA. Registration questionnaires in the intervention included detailed assessments of recent production in plots being registered to the intervention, and basic information for all other plots; and basic information on household structure and assets.
保护性农业（CA）是一种管理模式，即在休耕期覆盖土壤，尽量减少干扰，并利用固氮豆科植物为土壤补充氮。寻找鼓励 CA 的有效方法是一个数百年的老问题，在今天的撒哈拉以南非洲尤为突出。为了更好地理解这个问题，我们在马拉维南部进行了为期两年的干预，收集了农村生计和 CA 采用的数据。该干预措施评估了在两种不同的支付结构和三种不同的监测水平下 CA 的采用率。数据集包括基线和终线调查，涵盖了 1900 户家庭，以及与参与干预的参与者进行的调查。基线和终线问题包括了地块-作物层面的农场层面投入和生产、地块特征、家庭构成和资产、储蓄、贷款和其他收入来源、邻里特征以及对 CA 的看法等模块。干预措施中的注册问卷包括对正在向干预措施注册的地块的近期生产的详细评估，以及对所有其他地块的基本信息；以及家庭结构和资产的基本信息。
