讲座一:Sustainability of Forests Created by China's Sloping Land Conversion Program
主持人:李俊祥 教授

地址:闵行校区资环大楼148报告厅
报告简介:
China implemented the Sloping Land Conversion Program (SLCP) during 2001–2010, which led to the conversion of millions of hectares of marginal croplands to forests across 25 provinces involving 124 million people and costing the government 233 billion Yuan. Therefore, the sustainability of forests created by SLCP is of high stake. The sustainability of these forests strongly depends on the impacts of the program on participant farmer's livelihoods. In this study, we conducted household surveys on the program's impacts on the livelihoods of the participating farmers in Anhui, Hubei, and Shanxi provinces. Overall, it seems likely that the converted cropland will remain as forests in the near and medium future, with the possibility for the forests to be later reconverted back to croplands varying significantly across the three sites. The SLCP is associated with minor improvements in the livelihoods for a majority of participating farmers, and offers a significant safety net for households that are poor. We also found that farmers are overwhelmingly positive toward the program. To sustain these successes, continued monitoring of the forests is needed as current factors determining the success of the program may change. Further, studies in different regions of China would also be useful as SLCP outcomes strongly depend on the local context and conditions.
讲座二:Mapping Plant Productivity with Optical Remote Sensing: Theory and Practice

报告简介:
Plant productivity is a key term in global carbon cycle. Remote sensing is perhaps the only viable option that can map plant productivity repeatedly in a timely manner. In this talk, I will first review the basic theory of plant productivity, and its linkages with optical remote sensing. Then I will present some results of using a light-use-efficiency model in the Yangtze River Basin for the first decade of the 21st century. The study found that both land-cover/land-use change and climate variability had strong impacts on plant productivity. Due to China's reforestation and natural forest conservation efforts, plant productivity in the Yangtze River Basin increased significantly during the period, while climate change generally had negative impact, offsetting a significant proportion of the positive effect from the increase in forest cover. Therefore, accurate understanding of plant production over a large area over a significant period of time needs to account both factors.
