本レビューは、SADC地域の畜産バリューチェーンにおいて、気候変動緩和策を生産、加工、輸送、消費の各段階で特定し評価する。46の文献から、遺伝的改良、再生可能エネルギー導入、消費者意識向上などが約18-30%の排出削減と生産性向上に寄与することを示す。地域計画や国家政策との統合が鍵となる。

English

This review identifies climate change mitigation strategies across the livestock value chain in the SADC region, including genetic improvement, renewable energy, and consumer awareness. Based on 46 sources, it estimates 18-30% GHG reduction potential alongside productivity gains, and emphasizes coordination with regional and national policies for implementation.

📝 gxceed 編集解説 — Why this matters

In the global GX context

This paper provides a valuable synthesis of mitigation options in a developing region context, highlighting how livestock value chains can contribute to climate goals. While SADC-specific, the framework and strategies are transferable to other tropical and low-income regions, informing global discussions on sustainable livestock and climate policy integration.

👥 読者別の含意

🔬研究者:Offers a structured inventory of mitigation measures and their evidence base for the SADC region, useful for comparative studies or meta-analyses in similar agro-ecological zones.

🏛政策担当者:Provides actionable strategies aligned with the SADC Regional Agricultural Investment Plan; useful for designing national climate-smart livestock policies.

📄 Abstract（原文）

The livestock sector underpins food security, employment, and rural livelihoods across the Southern African Development Community (SADC), contributing up to 50% of agricultural GDP and supporting more than 60% of rural households. Yet climate change poses escalating threats through heat stress, declining pasture productivity, water scarcity, and vector-borne diseases that compromise productivity and economic resilience. This review identifies and locates effective climate change mitigation strategies along the livestock value chain, spanning production, processing, transport, and consumption, to promote sustainable, low-emission, and inclusive growth in the SADC region. A broad review of 46 peer-reviewed and institutional sources (2000–2024) was undertaken, focusing on livestock-related mitigation within SADC and comparable agro-ecological systems. Strategies were thematically categorized by value-chain stage and assessed for their emission-reduction and livelihood-enhancement potential. Local strategies include genetic improvement for low-methane and heat-tolerant breeds, adaptive rangeland and feed management, renewable-energy adoption in processing, climate-resilient transport infrastructure, and consumer awareness of low-emission products. Evidence suggests potential GHG-emission reductions of 18–30%, coupled with productivity gains and improved smallholder incomes. Coordinated implementation through the SADC Regional Agricultural Investment Plan (2021–2030) and national policies can transform the livestock sector into a climate-resilient driver of inclusive growth. Further research should quantify the socioeconomic feasibility and scaling potential of these strategies across production systems. Successful integration of climate change mitigation imperatives must be tailored to local biophysical conditions (e.g., rainfall, soil type) and socioeconomic contexts (e.g., market access, cultural practices).
