Better understanding of gender differences in the adoption of agricultural intensification strategies is crucial for designing effective policies to close the gender gap while sustainably enhancing farm productivity. We examine gender differences in adoption rates, likelihood and determinants of adopting strategy sets that enhance yields, protect crops, and restore soils in the West African Sahel, based on analysis of cereal production in Burkina Faso. Applying a multivariate probit model to a nationally representative household panel, we exploit the individual plot as unit of analysis and control for plot manager characteristics along with other covariates. Reflecting the socio-cultural context of farming combined with the economic attributes of inputs, we find that female managers of individual cereal fields are less likely than their male counterparts to adopt yield-enhancing and soil-restoring strategies, although no differential is apparent for yield-protecting strategies. More broadly, gender-disaggregated regressions demonstrate that adoption determinants differ by gender. Plot manager characteristics, including age, marital status, and access to credit or extension services do influence adoption decisions. Furthermore, household resources influence the probability of adopting intensification strategy sets differently by gender of the plot manager. Variables expressing the availability of household labor strongly influence the adoption of soil-restoring strategies by female plot managers. By contrast, household resources such as extent of livestock owned, value of non-farm income, and area planted to cotton affect the adoption choices of male plot managers. Rectifying the male bias in extension services along with improving access to credit, income, and equipment to female plot managers could contribute to sustainable agricultural intensification.
更好地理解农业集约化战略采用中的性别差异,对于制定有效的政策以缩小性别差距并在可持续提高农场生产力的同时至关重要。我们基于对布基纳法索谷物生产的分析,研究了西非萨赫勒地区采用提高产量、保护作物和恢复土壤的战略组合的采用率、可能性和决定因素方面的性别差异。我们将多元概率单位模型应用于具有全国代表性的家庭面板数据,以单个地块作为分析单位,并控制地块管理者特征以及其他协变量。考虑到农业的社会文化背景以及投入品的经济属性,我们发现,单个谷物地块的女性管理者比男性管理者采用提高产量和恢复土壤战略的可能性更小,尽管在采用保护产量战略方面没有明显差异。更广泛地说,按性别分类的回归表明,采用的决定因素因性别而异。地块管理者的特征,包括年龄、婚姻状况以及获得信贷或推广服务的机会,确实会影响采用决策。此外,家庭资源对采用集约化战略组合概率的影响因地块管理者的性别而异。表示家庭劳动力可用性的变量对女性地块管理者采用恢复土壤战略的影响很大。相比之下,诸如拥有牲畜的数量、非农收入的价值以及棉花种植面积等家庭资源会影响男性地块管理者的采用选择。纠正推广服务中的男性偏见,同时改善女性地块管理者获得信贷、收入和设备的机会,可能有助于实现可持续的农业集约化。
