Zero Hunger - Zero Emissions: Enabling the debate on how to feed the world whilst mitigating climate change

目前迫切需要找到一种方法，使社会能够就如何在一个受到危险程度气候变化威胁的世界中确保粮食安全展开艰难的辩论，同时大幅减少温室气体排放。这两个目标之间会有冲突、权衡，但也有潜在的共同利益，这在很大程度上取决于所选择的途径。然而，决策往往是高度技术性和自上而下的，忽略了社会各阶层，特别是最贫穷的人。粮食系统及其人口处于饥饿、贫困和环境目标的交叉点。建立有抵御力的粮食系统是适应气候变化的核心，但改变农业、土地利用和粮食系统以促进温室气体缓解可能更为重要，特别是考虑到《巴黎协定》中的承诺。孟加拉国是一个在粮食安全方面取得巨大进步的国家，同时也面临着气候变化带来的巨大挑战。中国做出了各种减排承诺，但其目前的政策和未来的发展轨迹存在可能危及这些目标的矛盾。农业为大多数人提供生计，占总排放量的40%，并可能面临越来越大的减排压力。对该国温室气体减排国家自主贡献计划的修订为就选择及其影响进行辩论提供了机会。本研究旨在设计和测试一个基于参与式情景方法的包容性和可复制的过程，使这些辩论能够以广泛的社会群体参与的方式进行，包括那些往往最没有发言权的尖锐人群。

There is an urgent need to find means by which societies can engage in difficult debates about how to ensure food security in a world threatened by dangerous levels of climate change, at the same time as making drastic cuts in greenhouse gas emissions. There will be conflicts, trade-offs but also potential co-benefits between these twin objectives depending very much on the pathways chosen. Decision-making though is often highly technical and top-down and omits sections of society, especially the poorest. Food systems and the people in them are at the intersection of hunger, poverty and environmental goals. Creating resilient food systems is central to climate change adaptation, but changing agriculture, land use and food systems to contribute to GHG mitigation will likely assume much greater importance particularly in light of the commitments in the Paris Agreement. Bangladesh is an example of a country that has made great strides in food security whilst facing enormous challenges from climate change. The country made various emission reductions commitments but its current policies and future development trajectories contain contradictions that might endanger these goals. Agriculture - which provides the livelihoods for the majority of people - is responsible for 40% of overall emissions and may come under increasing pressure to deliver reductions. The planned revision of the country's Nationally Determined Contribution to GHG emissions reduction offers an opportunity for debate on choices and their implications. This research aims to design and test an inclusive and replicable process based on participatory scenario methodology to enable those debates to take place in ways that involve broad swathes of society, including people at the sharp end who often have least voice.
