气候变化对我国水资源的最重要挑战是干旱的加剧,并直接影响到我国粮食安全。应对气候变化、确保粮食生产安全的关键措施是加强农田水利建设,通过采取减缓与适应措施提高农田水利保障能力。但是我国农田水利建设明显滞后已成为影响农业稳定发展和国家粮食安全的最大硬伤,实践证明农田水利健康发展离不开有效的政策指导与法律保障。完善现有农田水利政策,健全农田水利法律规范体系,不仅能改变我国目前农田水利薄弱的现状,也是我国落实联合国气候谈判协议的国际义务,更为我国农业可持续发展与国家粮食安全奠定了坚实基础。
The most important challenge to climate change in our country’s water resources is the aggravating drought and the direct impact on China’s food security. The key measures to tackle climate change and ensure the safety of food production are to strengthen the construction of irrigation and water conservancy and to improve the ability of ensuring farmland water conservancy through mitigation and adaptation measures. However, the obvious lag of construction of farmland and water conservancy in our country has become the biggest flaw that affects the steady development of agriculture and national food security. Practice has proved that the healthy development of farmland water conservancy is inseparable from effective policy guidance and legal guarantee. Perfecting the existing irrigation and water conservancy policies and improving the legal norms system of farmland water conservancy not only can change the present situation of weak irrigation and water conservancy in our country but also our country’s international obligation to implement the UN climate negotiation agreement and lay a solid foundation for our country’s agricultural sustainable development and national food security basis.
