水安全与粮食安全密不可分。农业约占全球淡水取水量的 70% 至 72%，这使其成为实现可持续水资源管理的核心。若不改变农业中水和养分的利用方式，就不可能有实现可持续发展目标（SDG）6——确保人人获得清洁饮水和卫生设施——的可靠路径。同样，在水不安全不断加剧或养分利用不足的世界里，也不可能实现关于零饥饿的 SDG 2。化肥和改进的农艺措施对于维持养活不断增长的世界人口所需的农业生产力不可或缺，这使得水和植物养分的高效管理对未来粮食安全愈发重要。这两大议程要么共同成功，要么共同失败。然而在许多国家，农业资源的治理与管理仍然彼此割裂：水、植物营养、土壤健康和作物生产力往往由相互分离的政策和计划来处理，限制了同时提升用水效率与改善水质的机会。本白皮书提出，将水与植物营养协同管理是最有效……
Water security and food security are inseparable. Agriculture accounts for approximately 70% to 72% of global freshwater withdrawals, making it central to achieving sustainable water management. There is no credible pathway to Sustainable Development Goal (SDG) 6 – ensuring clean water and sanitation for all – without transforming the way water and nutrients are used in agriculture. Equally, there is no pathway to SDG 2 on zero hunger in a world of escalating water insecurity or insufficient nutrient use. Fertilizers and improved agronomy are essential to sustaining the agricultural productivity needed to feed a growing global population, making the efficient management of water and plant nutrients increasingly important to future food security. The two agendas succeed together or fail together. Yet in many countries, the governance and management of agricultural resources remain fragmented: water, plant nutrition, soil health, and crop productivity are often addressed through separate policies and programs, limiting opportunities to improve both water use efficiency and water quality. This white paper argues that managing water and plant nutrition together is one of the most effe…
