As climatic and socio-economic changes progress, the decoupling between water retention and usage widens. In terms of water demand, agriculture and crop production are the sectors that have the highest than other industries. Also, agriculture is the most climate-dependent production sector; thus, it is necessary to accurately assess the impacts of climate change on the agriculture sector to achieve sustainability. i.e. for the sustainable agriculture in the era of climate change needs to find solutions for the retention and proper utilization of water. And also, agro-environment affected by environmental change, such as deforestation had an impact on cropland stability, water resource and productivity. In case of North Korea, lots of forest was degraded and converted to cropland, but it could be reason for decreasing food security. To contribute solving these problems, this book covered agriculture and water studies by climate change and environmental change using spatial modelling technique focus on Korean Peninsula.
