严重的气候变化给粮食安全和营养带来风险
本文讨论了与持续和预计的气候变化有关的粮食安全和营养的严重风险,特别是全球变暖、干旱、洪水和降水等极端气候和天气。我们特别考虑了由于收入较低、获得营养食品的机会较少或社会歧视而对易受粮食不安全和营养不良影响的人群的影响。该文件在粮食安全和营养的背景下定义了与气候相关的“严重风险”,使用了一系列标准,包括不良后果的严重程度和可能性、风险发生的时间以及降低风险的能力。粮食安全和营养面临的严重气候变化风险极有可能导致数百万人普遍和持续的粮食不安全和营养不良,有可能在粮食系统之外产生连锁反应,我们预防或充分应对这些风险的能力有限。该文件使用国际商定的粮食安全和营养风险定义来描述不利后果的严重程度。此外,该论文根据文献中使用不同气候变化情景和共同的社会经济途径的研究结果,评估了气候变化引发的粮食安全和营养风险可能变得严重的条件。最后,该文件提出了适应选择,包括现在可以采取的机构管理和治理行动,以防止或减少对未来人类粮食安全和营养的严重气候风险。

期刊介绍: Climate Risk Management publishes original scientific contributions, state-of-the-art reviews and reports of practical experience on the use of knowledge and information regarding the consequences of climate variability and climate change in decision and policy making on climate change responses from the near- to long-term. The concept of climate risk management refers to activities and methods that are used by individuals, organizations, and institutions to facilitate climate-resilient decision-making. Its objective is to promote sustainable development by maximizing the beneficial impacts of climate change responses and minimizing negative impacts across the full spectrum of geographies and sectors that are potentially affected by the changing climate.
