Abstract

Climate change threatens the livelihoods of Sub-Saharan African farmers through increased droughts. Livestock donation programs offer a potential solution, but their effectiveness under climate stress remains unclear. This study assesses the economic viability of integrating climate-smart technologies (cowsheds and biogas plants) into these programs in Rwanda. Using a stochastic benefit–cost analysis from the beneficiary perspective, we evaluate the net gains for households receiving heifers compared to the current program. Our findings reveal that integrating climate-smart technologies significantly enhances economic viability. Households with cows and climate-smart technologies can possibly realise net benefits 3.5 times higher than the current program, with benefit–cost ratios reaching 5:1. Beyond economic benefits, adopting biogas reduces deforestation, greenhouse gas emissions, and respiratory illness risks. This study demonstrates that integrating climate-smart technologies into livestock donation programs can generate positive economic, environmental, and health benefits, leading to more resilient and sustainable smallholder systems. However, overcoming implementation challenges requires tailored policy packages addressing local barriers.

气候智能技术对卢旺达小农牲畜捐赠计划成功的影响

气候变化导致干旱加剧，威胁着撒哈拉以南非洲农民的生计。牲畜捐赠计划提供了一个潜在的解决方案，但其在气候压力下的有效性仍不明确。本研究评估了在卢旺达将气候智能技术（牛舍和沼气厂）纳入这些计划的经济可行性。我们从受益人的角度出发，采用随机效益成本分析法，评估了与现行计划相比，获得小母牛的家庭的净收益。我们的研究结果表明，整合气候智能技术可显著提高经济可行性。拥有母牛和气候智能技术的家庭所能实现的净收益可能是目前计划的 3.5 倍，收益成本比达到 5:1。除经济效益外，采用沼气还能减少森林砍伐、温室气体排放和呼吸道疾病风险。这项研究表明，将气候智能技术纳入牲畜捐赠计划可以产生积极的经济、环境和健康效益，从而提高小农系统的适应能力和可持续发展能力。然而，要克服实施过程中的挑战，就需要针对当地障碍量身定制一揽子政策。

期刊介绍： The Earth''s biosphere is being transformed by various anthropogenic activities. Mitigation and Adaptation Strategies for Global Change addresses a wide range of environment, economic and energy topics and timely issues including global climate change, stratospheric ozone depletion, acid deposition, eutrophication of terrestrial and aquatic ecosystems, species extinction and loss of biological diversity, deforestation and forest degradation, desertification, soil resource degradation, land-use change, sea level rise, destruction of coastal zones, depletion of fresh water and marine fisheries, loss of wetlands and riparian zones and hazardous waste management. Response options to mitigate these threats or to adapt to changing environs are needed to ensure a sustainable biosphere for all forms of life. To that end, Mitigation and Adaptation Strategies for Global Change provides a forum to encourage the conceptualization, critical examination and debate regarding response options. The aim of this journal is to provide a forum to review, analyze and stimulate the development, testing and implementation of mitigation and adaptation strategies at regional, national and global scales. One of the primary goals of this journal is to contribute to real-time policy analysis and development as national and international policies and agreements are discussed and promulgated.
