Issues on Low-carbon Agriculture:From Theory to Practices

Low-carbon economy has become a global hot spot,known as the Fourth Technological Revolution under global climate change.At present,greenhouse gas emissions have already imperiled agriculture and food security.Low-carbon agriculture becomes the inevitable trend of economic and social development.Currently,the concept of low-carbon agriculture has turned from scientific theory to practices,including its approach to development:(1)development of new energy resources,promoting clean technologies;(2)optimize the farming systems,raising multiple cropping index;(3)develop and popularize fine varieties to extend the chain of emission reduction;(4)improve the fertilization techniques,optimize the nutrient management;(5)implementation of conservation tillage,reduce carbon loss;(6)rational development of grass industry,protection of grassland resources;(7)development of bio-energy resources,raising the application of cattle manure;(8)farming pollution remediation and extending scale livestock breeding.Safeguard mechanisms of the low-carbon agriculture development include:(1)improve relevant laws and regulations;(2)the adjustment of economic growth mode;(3)rely on scientific and technological progress;(4)increase public participation.Development of low-carbon agriculture is important for sustainable use of resources and enhanced the agriculture foundation,through agricultural measures to mitigate global climate change has important strategic significance.
