南部アフリカのインコマティ・ウスツ越境流域を対象に、NDCと地域開発・協力の相互作用を内容分析・聞き取り・因果ループ図で分析した研究。水・エネルギー・食料（WEF）ネクサスには相乗効果がある一方、地域の開発志向のフィードバックがNDCの野心を損なう構造を明らかにする。NDCの誓約レビュー型からボトムアップ型の開発・気候統合アプローチへの転換を促す。
English
Using content analysis, interviews, and causal loop diagrams in the Inkomati-Usuthu transboundary basin, this study examines how NDCs interact with regional development and cooperation. It finds WEF-nexus synergies anchored in infrastructure, but local development feedback loops—such as land-use change for sugarcane and macadamia—undermine NDC ambition. The work argues for shifting from pledge-review NDCs to bottom-up development-climate integration in transboundary basins.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本企業・政策には直接の接点は薄いが、NDCと開発政策の整合という論点は、日本のNDC更新やアジアの越境水・資源ガバナンスを考える上で参照価値がある。
In the global GX context
Speaks to the global challenge of aligning NDCs with national development priorities and to ISSB/TCFD-adjacent debates on how policy ambition translates into real-economy outcomes. Offers a WEF-nexus method for assessing whether development pathways support or undermine climate pledges, relevant to transition-plan credibility discussions.

📄 Abstract（原文）
The dichotomy between climate change, sustainable development, and critical resource demands sits at the crux of transboundary basin cooperation and climate action. The Inkomati-Usuthu manifests a national and supranational development-climate action dichotomy that shapes policy and climate action. Competing resource demands, increase climate variability, and complex geopolitical governance systems, creating feedback loops that influence adaptation, mitigation, cooperation, and development. This study employs a three-step methodology that incorporates iterative content analysis, key informant interviews, and causal loop diagrams to investigate the interface among nationally determined contributions (NDCs), regional development, and cooperation. Findings reveal synergistic relationships across the water-energy-food (WEF) sectors, anchored in infrastructure development. Water-for-energy and energy-for-water configurations lead to dominant policy development feedback loops. However, local synergistic development configurations undermine NDC ambitions. Development configurations catalyse resource exploitation, undermining NDC ambitions. In practice, national demands prompted basin-wide interactions. For example, increased energy demand directly affected basin-wide water export agreements. Thus, cooperation for development created institutional arrangements aligned with the maximisation of development, potentially undermining commitments to climate action. For instance, increased sugarcane and macadamia production has improved food security and expanded employment. However, the land-use change negatively impacts biodiversity, and increased greenhouse gas emissions, undermining NDC objectives. Examining the interlinkages between climate action and development using a WEF-nexus approach could catalyse and enhance multi-sectoral scenario planning for resilience and development. This work contributes to accelerating the transition from the NDC pledge-review system to a bottom-up development and climate action approach in transboundary river basins.
