Abstract

In Tanzania, agro-pastoral practices have evolved as a response to climate variability. However, the economic evaluation of adaptation strategies in these systems is limited. This case study explores the cost-effectiveness of various climate adaptation strategies adopted by agro-pastoralists in the semi-arid regions of northern and central Tanzania. Using primary data from 411 households, the study applied cost-benefit analysis (CBA) tools including net present value (NPV), benefit-cost ratio (BCR), and internal rate of return (IRR) to assess planned adaptation versus business-as-usual (BAU) scenarios. Results highlight that crop diversification, drought-tolerant crops, micro-catchment rainwater harvesting (MCRWH), drip irrigation, and livestock diversification are economically viable strategies under changing climatic conditions. This study provides practical insights into how agro-pastoralists can improve climate resilience through locally adapted strategies.

耐气候农业：坦桑尼亚农牧农民适应战略的经济可行性

在坦桑尼亚，农牧实践已经演变为对气候变化的反应。然而，对这些系统中适应策略的经济评价是有限的。本案例研究探讨了坦桑尼亚北部和中部半干旱地区农牧民采取的各种气候适应战略的成本效益。利用来自411个家庭的原始数据，该研究应用成本效益分析（CBA）工具，包括净现值（NPV）、效益成本比（BCR）和内部收益率（IRR），来评估计划适应与常规经营（BAU）情景的对比。结果表明，在气候条件不断变化的情况下，作物多样化、耐旱作物、微集水区雨水收集、滴灌和牲畜多样化是经济上可行的策略。这项研究为农牧民如何通过因地制宜的策略提高气候适应能力提供了实际见解。

期刊介绍： The journal Climate Services publishes research with a focus on science-based and user-specific climate information underpinning climate services, ultimately to assist society to adapt to climate change. Climate Services brings science and practice closer together. The journal addresses both researchers in the field of climate service research, and stakeholders and practitioners interested in or already applying climate services. It serves as a means of communication, dialogue and exchange between researchers and stakeholders. Climate services pioneers novel research areas that directly refer to how climate information can be applied in methodologies and tools for adaptation to climate change. It publishes best practice examples, case studies as well as theories, methods and data analysis with a clear connection to climate services. The focus of the published work is often multi-disciplinary, case-specific, tailored to specific sectors and strongly application-oriented. To offer a suitable outlet for such studies, Climate Services journal introduced a new section in the research article type. The research article contains a classical scientific part as well as a section with easily understandable practical implications for policy makers and practitioners. The journal''s focus is on the use and usability of climate information for adaptation purposes underpinning climate services.
