农业部门面临着与气候不确定性增加有关的多重挑战，造成严重冲击，包括极端天气事件频率增加、新的病虫害风险、土壤退化以及收获前后的粮食损失。地缘政治不稳定和能源价格波动对化肥供应和生产成本的影响进一步加剧了这种情况。净零战略对于实现粮食安全和应对负面环境影响至关重要。这份展望文件审查和评估了实现净零排放的最可行的选择（行动），重点是英国的耕地/畜牧业和保护作物部门。该方法基于对相关文献的综合，再加上专家意见，采用整体PESTLE（政治、环境、社会、技术、法律的和环境）方法对行动进行分类，从而制定了实现净零排放的路线图。PESTLE分析表明，有技术上和经济上可行的行动，需要根据其在两个作物部门的调查实施的难易程度来确定优先顺序。这些行动包括：（一）更好地实现净零排放的政策变革;（二）循环经济方法;（三）信息的连通性和可获得性;（四）增强抵御冲击的能力;（五）改变饮食、营养和生活方式;（六）目标设定和实现;（七）农业经济和生计。利益攸关方和决策者可以利用这些产出为政策提供信息，并推动全球粮食和环境安全发生有意义的变化。
The agricultural sector faces multiple challenges linked to increased climate uncertainty, causing severe shocks including increased frequency of extreme weather events, new pest and disease risks, soil degradation, and pre and postharvest food losses. This situation is further exacerbated by geopolitical instability and volatility in energy prices impacting on fertiliser supplies and production costs. Net zero strategies are vital to achieve both food security and address negative environmental impacts. This perspective paper reviews and assesses the most viable options (actions) to achieve net zero with a focus on the arable/livestock and protected cropping sectors in the UK. The methodology was based on a synthesis of relevant literature, coupled with expert opinions using the holistic PESTLE (Political, Environmental, Social, Technological, Legal and Environmental) approach to categorise actions, leading to formulation of a roadmap to achieve net zero. The PESTLE analysis indicated that there are technically and economically viable actions available which need to be prioritised depending on the ease of their implementation within the two crop sectors investigated. These actions include (i) policy changes that are better aligned to net zero; (ii) circular economy approaches; (iii) connectivity and accessibility of information; (iv) increased resilience to shocks; (v) changing diets, nutrition and lifestyles; (vi) target setting and attainment; and (vii) farm economics and livelihoods. The outputs can be used by stakeholders and decision makers to inform policy and drive meaningful changes in global food and environmental security.
