In this letter, we present the methodology and accuracy assessment of a new regional 250-m spatial resolution land cover map of insular Southeast Asia. Nearly 500 daily Moderate Resolution Imaging Spectroradiometer images (acquired 2 January–3 July 2010) were used in the production of the map. Additionally, peatland maps, elevation information and Daichi-Advanced Land Observing Satellite mosaic data were utilized in the mapping process.
A ca. 2010, 30m resolution map depicting annually tilled areas across the conterminous United States was developed. Input sources included fouryears, spanning 2008–2011, of annual national-level coverage Cropland Data Layer (CDL) land cover classifications as produced by the National Agricultural Statistics Service. Derived total land area under tillage from the aggregate CDL product equaled 112.8million hectares (278.7million acres).
The year 2011 highlighted ongoing challenges to global food security, from food price volatility, extreme weather shocks, and famine to unrest and conflicts. On the policy front, major developments at the global and national levels both offered grounds for encouragement and pointed to areas where further action is needed.

„Kísértet járja be Európát és Észak-Amerikát: az erdőpusztulás kísértete.” Ezzel a drámai hangvételű mondattal kezdődik a World Resources 1986. évi kötetének erdőkkel foglalkozó része, ami a 70-es években kezdődött nagyarányú erdőpusztulás világméretű „jajkiáltása” volt, melynek visszhangja: „Mentsétek meg a Föld erdeit – amíg nem késő, amíg van mit megmenteni és megőrizni!” Nemzetközi tudományos, világméretű társadalmi fórumok témájává vált az erdő. Az emberiség egyre jobban ráébredt arra, hogy az erdő az emberiség létfeltételeinek elengedhetetlen része.
Depuis 2007, deux séries successives d’envolée des prix des denrées alimentaires ont causé la faim ou la malnutrition pour des millions de personnes dans le monde. Les mêmes facteurs qui avaient contribué à la hausse des prix en 2007-2008 ont refait surface en 2011 et ont pour nom : la baisse du taux de croissance de la productivité agricole, le niveau élevé du coût de l’énergie favorisant l’expansion de la production de biocarburants, la dépréciation du dollar américain, une forte demande des pays émergents en matière de produits agricoles et les bouleversements climatiques.
This 2012 Global Food Policy Report is the second in an annual series that provides an in-depth look at major food policy developments and events. Initiated in response to resurgent interest in food security, the series offers a yearly overview of the food policy developments that have contributed to or hindered progress in food and nutrition security. It reviews what happened in food policy and why, examines key challenges and opportunities, shares new evidence and knowledge, and highlights emerging issues.
Nelle ultime due edizioni l’IndiceGlobale della Fame (Global Hunger Index - GHI) aveva approfondito temi che sono tuttora di grande attualità: la denutrizione infantile e la volatilità dei prezzi dei beni alimentari. Gran parte dell’Asia negli ultimi anni ha visto il PIL di diversi Paesi crescere con tassi superiori al 7%, ma la maggiore ricchezza non si è sempre tradotta in unmiglior accesso a un’alimentazione di qualità.
