项目摘要
In tropical Africa, agriculture is mostly upland crops by traditional system, which destroys upland forests, and lowlands have not been yet widely used. Tropical Africa's total potential for lowland sawah, paddy, based farming is more than 20 million hectares. Among the lowlands, inland valleys are especially important for sawah development. The sustainable productivity of lowland sawah systems is over ten times as high as that in upland cropping systems because of Geological fertilization, i.e., soil, nutrients and water flow, from upland to lowland in a watershed. Because of this, if these 20 million ha of potential land were turned into sawah fields in 50 to 100 years from now, that would not only bring about food for 500 million to one billion people but also prevent deforestation of more than 200 million ha, which would ultimately pave the way to restore forest. Based on the three years of research, we proposed the ecotechnology based strategy and practical and participatory approached for the reforestation and the checking desertification through lowland sawah development in West Africa. The carbon to be fixed by restored forests will reach about 2.5-5 tons per ha per year and will total to 500 million to one billion tons a year in 50-100 years from now.
在热带非洲,农业主要是传统的旱地作物,这破坏了高地森林,低地尚未得到广泛利用。热带非洲的低地萨瓦、水稻和以农业为基础的总潜力超过2000万公顷。在低地,内陆山谷对萨瓦的发展特别重要。由于地质施肥,低地萨瓦系统的可持续生产力是高地种植系统的十倍以上,即,土壤、养分和水在分水岭中从高地流向低地。因此,如果这2 000万公顷潜在土地在50年至100年后变成sawah田地,这不仅将为5亿至10亿人带来粮食,而且还将防止2亿多公顷森林被砍伐,这将最终为恢复森林铺平道路。在三年研究的基础上,我们提出了基于生态技术的战略和切实可行的参与式方法,以通过西非低地萨瓦开发来造林和防治荒漠化。每年每公顷森林所固定的碳将达到2.5-5吨,从现在起的50-100年内,每年将达到5亿至10亿吨。
