Despite strong economic growth in many countries of the Horn and Sahel, environmental and demographic changes coupled to low levels of political inclusion and high instability mean that the risk of acute food crises is likely to increase. Conflict and geopolitics act as risk multipliers, meaning that full-blown famine remains a real threat, as was seen most recently in Somalia during 2011.
Precision Agriculture is a hot topic these days as researchers look for ways to reduce the massive amounts of chemicals that are currently sprayed on food crops. A new research paper describes one of the ways robots may help in Early Season Site-Specific Weed Management (ESSWM). In the study, a UAV equipped with a multispectral camera collected images of sunflower field infested with naturally occurring weeds. Similar imaging techniques using traditional satellite and aerial methods to adjust herbicide distribution have yielded up to 50% reduction in the total amounts of herbicides used. The researchers hope to replicate this process using the less expensive flying robot. Read More
The first ever interactive online platform providing open access to all agricultural spatial data and information in Ghana was yesterday launched in Accra. The website, jointly created by the USAID/ADVANCE and the Centre for Remote Sensing and Geographic Information Services (CERSGIS) of the University of Ghana, Legon, aims to provide agricultural related spatial data set in a user friendly mode to stakeholders of the sector.
Agriculture is a major actor in spurring global climate change. The sector is already responsible for at least 10-12 percent of global greenhouse gas (GHG) emissions, and agricultural emissions are expected to increase by more than 50 percent by 2030.
