Low Carbon Assessment and Planning of Agricultural Space in Zhoushan Based on Multi-element Nexus

Abstract:

A “water-energy-food-land-carbon ”Nexus（WEFLC） analysis framework was established with food production and carbon emissions as expected and undesired outputs， respectively. Typical agricultural production cases of farming， livestock breeding， and aquaculture in Zhoushan islands were selected to conduct the agricultural space assessment and low carbon planning. The order of unit output value and carbon emissions per unit area is livestock breeding， aquaculture， and farming. The total output value of livestock breeding is greatly affected by the trend of carbon trading. While maintaining the same food output， livestock breeding， aquaculture， and farming section can reduce energy， water， and land resource consumption， and therefore， low carbon emissions are realized for agricultural production by employing photovoltaics and improving the efficiency of water use as well as introducing organic waste-disposal technologies .
