The Impacts of Climate Change and Human Activities on Cropland Net Primary Productivity in Bangladesh, India and Myanmar WANG Chunyu, WANG Junbang 气候变化和人类活动对孟印缅地区农田净初级生产力的影响 王春雨, 王军邦 DOI: 10.5814/j.issn.1674-764x.2024.04.003 Abstract: Under global change and climate variations, determining the impacts of climate change and human ac tivities on cropland net primary productivity (NPP) in Bangladesh, India and Myanmar (BIM) is of great significance for identifying yield-limiting factors, making adaptive agricultural management plans, and improving yields. Based on the GLOPEM-CEVSA model, through an integration of remote sensing data and LAI simulation, we investigated the impacts and spatiotemporal changes of water and human activities on BIM from 1982 to 2015. Three types of cropland NPPs were considered: actual NPP ( NPP A ), NPP affected by temperature and water ( NPP WT ), and NPP only affected by tempera
