Changing climatic conditions present new challenges for agricultural development in sub-Saharan Africa. Sorghum has proven to be an adaptable and resilient crop despite limited funding for crop development. Recent breeding efforts target hybrid and perennial technologies that may facilitate adaptation to climate change. Advantages of perennial crops over their annual counterparts include improved soil quality and water conservation and reduced inputs and labor requirements. In contrast, hybrid crops are often bred for improved grain yield and earlier maturation to avoid variable conditions. We use discrete choice experiments to model adoption of sorghum as a function of attributes that differ between these technologies and traditional varieties in Mali. Overall, the main perceived advantage of perennial crops is agricultural ecosystem services such as soil improvement, while adoption of hybrid crops is hampered by the inability to reuse seed. Women farmers are less concerned about higher labor requirements associated with perennial crops and the ability to reuse hybrids seeds than male farmers. Farmers prefer traditional sorghum to perennial sorghum and are indifferent between traditional and hybrid sorghum. These findings have important policy implications for understanding tradeoffs that are central to farmer decision making when it comes to breeding technologies for climate adaptation.

在马里应对农业生态系统服务与适应气候变化之间的权衡

不断变化的气候条件对撒哈拉以南非洲的农业发展提出了新的挑战。尽管用于作物开发的资金有限，但高粱已被证明是一种适应性强且恢复力强的作物。最近的育种工作针对可能促进适应气候变化的杂交和多年生技术。多年生作物相对于一年生作物的优势包括改善土壤质量和节水以及减少投入和劳动力需求。相比之下，杂交作物的培育通常是为了提高谷物产量和早熟，以避免条件变化。我们使用离散选择实验将高粱的采用建模为这些技术与马里传统品种之间不同的属性的函数。全面的，多年生作物的主要优势是土壤改良等农业生态系统服务，而杂交作物的采用受到无法再利用种子的阻碍。与男性农民相比，女性农民不太关心与多年生作物相关的更高劳动力需求以及重复使用杂交种子的能力。与多年生高粱相比，农民更喜欢传统高粱，对传统高粱和杂交高粱无感。这些发现对于理解在气候适应育种技术方面对农民决策至关重要的权衡具有重要的政策意义。与男性农民相比，女性农民不太关心与多年生作物相关的更高劳动力需求以及重复使用杂交种子的能力。与多年生高粱相比，农民更喜欢传统高粱，对传统高粱和杂交高粱无感。这些发现对于理解在气候适应育种技术方面对农民决策至关重要的权衡具有重要的政策意义。与男性农民相比，女性农民不太关心与多年生作物相关的更高劳动力需求以及重复使用杂交种子的能力。与多年生高粱相比，农民更喜欢传统高粱，对传统高粱和杂交高粱无感。这些发现对于理解在气候适应育种技术方面对农民决策至关重要的权衡具有重要的政策意义。
