International Food Security Assessment: 2012-22 Last Updated on 2014-10-26 16:56:26   Food security is estimated to improve slightly in 2012 as the number of food-insecure people in the 76 countries covered in this report declines from 814 million in 2011 to 802 million in 2012. The share of the population that is food insecure remains at 24 percent. Over the next decade, the share of the population that is food insecure is projected to decline from 24 percent in 2012 to 21 percent in 2022, but the number of food insecure people is projected to increase by 37 million. Regionally, food insecurity is projected to remain most severe in Sub-Saharan Africa. Food-insecure people are defined as those consuming less than the nutritional target of roughly 2,100 calories per day per person. The U.S. Department of Agriculture's Economic Research Service (ERS) has, since the late 1970s, reported annually on food security in a number of developing countries. A key... More »
Changing climate, changing forests Last Updated on 2012-08-16 00:00:00 The report focuses on established science and offers recommendations for decision-makers on steps that will make forests more resilient to the effects of climate change. It is a General Technical Report, published by the U.S. Forest Service, and was authored by Lindsey Rustad, John Campbell, Jeffrey S. Dukes, Thomas Huntington, Kathy Fallon Lambert, Jacqueline Mohan, and Nicholas Rodenhouse. The report concludes that the climate of the Northeast has changed and is likely to change more. The report's Abstract is presented here, and the full document may be downloaded at the link at the end of this page. Changing climate, changing forests: The impacts of climate change on forests of the northeastern United States and eastern Canada Key Words:┬átemperate forests, biogeochemistry, carbon cycle, water cycle, climate models, invasive species, wildlife, climate adaptation,...

CIGAR Consortium Last Updated on 2012-07-09 12:25:24 The CGIAR Consortium is a global partnership that unites organizations engaged in research for a food secure future. CGIAR Consortium The name CGIAR comes from the acronym for the Consultative Group on International Agricultural Research. In 2008 the CGIAR underwent a major transformation. To reflect this and yet retain our roots we have kept CGIAR as our name. CGIAR research is dedicated to reducing rural poverty, increasing food security, improving human health and nutrition, and ensuring more sustainable management of natural resources. It is carried out by 15 Centers, that are members of the CGIAR Consortium, in close collaboration with hundreds of partner organizations, including national and regional research institutes, civil society organizations, academia, and the private sector. The 15 Research Centers generate and disseminate knowledge,... More »
Urban forest loss Last Updated on 2012-02-24 00:00:00 New Orleans, Albuquerque, and Houston are among U.S. urban areas that are losing their trees. Nation’s urban forests losing ground National results indicate that tree cover in urban areas of the United States is declining at a rate of about 4 million trees per year, according to a U.S. Forest Service study published recently in Urban Forestry & Urban Greening. Tree cover in 17 of the 20 cities analyzed in the study declined while 16 cities saw increases in impervious cover, which includes pavement and rooftops. Land that lost trees was for the most part converted to either grass or ground cover, impervious cover or bare soil. Of the 20 cities analyzed, the greatest percentage of annual loss in tree cover occurred in New Orleans, Houston and Albuquerque. Researchers expected to find a dramatic loss of trees in New Orleans and said that it is most likely due... More »
Height of Earth's forests Last Updated on 2012-02-20 00:00:00 Knowing the height of Earth's forests is critical to estimating their biomass. This map can be used to improve global efforts to monitor carbon. NASA Map Sees Earth's Trees in a New Light A National Aeronautics and Space Administration (NASA)-led science team has created an accurate, high-resolution map of the height of Earth's forests. The map will help scientists better understand the role forests play in climate change and how their heights influence wildlife habitats within them, while also helping them quantify the carbon stored in Earth's vegetation. Scientists from NASA's Jet Propulsion Laboratory, Pasadena, Calif.; the University of Maryland, College Park; and Woods Hole Research Center, Falmouth, Mass., created the map using 2.5 million carefully screened, globally distributed laser pulse measurements from space. The light detection... More »
