国际肥料开发中心 (IFDC) 正在研究和减少孟加拉国低地水稻种植造成的温室气体排放。
Through a new component of the USAID-funded Accelerating Agriculture Productivity Improvement (AAPI), the project will quantify the environmental benefits of fertilizer deep placement (FDP) technology and build Bangladesh’s national capacity to incorporate climate change activities into development programs. The new activity integrates the U.S. government’s Global Climate Change Initiative into its Feed the Future initiative. Bangladesh is a priority country for both initiatives.
Rice farms account for 85% of Bangladesh’s agricultural land and emit greenhouse gases in the form of carbon dioxide, methane and nitrous oxide. Runoff of excess nitrogen and phosphorus can severely impact wetland and coastal habitats, and the ineffective management of crops, soils, water and nutrients not only leads to lower yields and inefficient resource use but also results in higher GHG emission rates.
“FDP is likely to significantly reduce GHG emissions, particularly nitrous oxide and nitric oxide emissions, and will further mitigate climate change by substantially reducing ammonia volatilization losses and the nitrification process in the wetlands,” said Dr. Upendra Singh, IFDC principal scientist-systems modeling (soil fertility).
“The AAPI project is expanding FDP technology to over a million hectares involving 2.5 million farmers,” said John Allgood, director of IFDC’s EurAsia Division. “Altogether, FDP technology is used on more than 12% of Bangladesh’s rice-growing land. FDP technology is helping to increase yields and reduce the cost of fertilization. It also helps reduce negative impacts on Bangladesh’s ecosystems and thereby contributes to the country’s resilience to climate change.”
IFDC 在非洲绿色革命联盟 (AGRA) 的资助下，还推出了名为 Mfarms 的 ICT 平台，以支持将商业解决方案引入农业。
Mfarms 是一个基于网络和手机的平台 (www.mfarms.org)，它提供负担得起的工具，用于在农业价值链上的参与者之间建立联系、提高沟通和运营效率。该平台由加纳公司 Image-AD Ltd 开发。
该平台具有使农业和农业综合企业成为有利可图的企业的巨大潜力，旨在通过允许组织、协会和可识别的团体为其大量分散在各地的成员或附属机构提供服务来提高运营效率。作为决策支持工具，Mfarms 可用于生产和采购计划、警报和扩展信息的广播、生产技术和时间表遵守情况的验证，以及生产和交易成本的计算。
目前，Mfarms 正被成功地用于将小农户与结构化主食市场联系起来，并用于农业投入品和食品的规划、监测和营销。
