Marine Gravity from Satellite Altimetry Data on slight variations of the pull of gravity over the oceans are recorded with satellite altimetry, and are then combined to map the seafloor globally. Get the Marine Gravity Map: Global Data Grids CHAPTER 2: CROP WATER NEEDS Crops need water for transpiration and evaporation (see Volume 1, Section 4.2). The plant roots suck or extract water from the soil to live and grow. The main part of this water does not remain in the plant, but escapes to the atmosphere as vapour through the plant's leaves and stem. This process is called transpiration. Transpiration happens mainly during the day time. Habitat-based cetacean density models for the U.S. Atlantic and Gulf of Mexico (2015 Version) Abstract Cetaceans are protected worldwide but vulnerable to incidental harm from an expanding array of human activities at sea. Managing potential hazards to these highly-mobile populations increasingly requires a detailed understanding of their seasonal distributions and habitats. Pursuant to the urgent need for this knowledge in U.S. waters of the western North Atlantic and Gulf of Mexico, we integrated aerial and shipboard cetacean surveys conducted by five scientific organizations over 23 years and linked them to environmental data relating to cetacean habitat, such as sea surface temperature and chlorophyll concentration, obtained from satellite remote sensing and ocean models. Using distance sampling methodology, we built statistical models of cetacean density—the number of individual animals found per square kilometer of area—from environmental variables for 26 species and 3 multi-species guilds, and produced maps showing average density across the modeled region.
Buying farmland abroad: Outsourcing's third wave EARLY this year, the king of Saudi Arabia held a ceremony to receive a batch of rice, part of the first crop to be produced under something called the King Abdullah initiative for Saudi agricultural investment abroad. It had been grown in Ethiopia, where a group of Saudi investors is spending $100m to raise wheat, barley and rice on land leased to them by the government. The investors are exempt from tax in the first few years and may export the entire crop back home. Meanwhile, the World Food Programme (WFP) is spending almost the same amount as the investors ($116m) providing 230,000 tonnes of food aid between 2007 and 2011 to the 4.6m Ethiopians it thinks are threatened by hunger and malnutrition.
Apps for Development Achieving the Millennium Development Goals is a global effort involving many people, governments, and international agencies. Besides the official list of indicators used to measure progress at the national level, there many other sources of data that can help to develop, test, and implement new strategies for reaching the goals – at the local, national, regional, and global levels. Listed here are sources of data and other information about the challenges of achieving the goals. But don’t stop with these. Identify other sources of data and new strategies for improving the lives of people around the world.
Free mapping data will elevate flood risk knowledge For the past 17 years we have been capturing LIDAR (Light Detection & Ranging) data in England. LIDAR uses a laser to scan and map the landscape from above and is widely considered to be the best method for collecting very dense and accurate elevation data across the landscape. We use LIDAR to help the work of the Environment Agency in many ways, including creating flood models, assessing coastal change and analysing how land is used. We now have an extensive archive of aerial LIDAR data covering nearly three quarters (72%) of England – the data mainly covers flood plains, coastal zones and urban areas.
The Price of Water 2013: Up Nearly 7 Percent in Last Year in 30 Major U.S. Cities; 25 Percent Rise Since 2010 Utilities tinker with rate structures designed to stabilize revenue. Graphic © Jinah Park / Circle of Blue By Brett Walton Circle of Blue Water prices in 30 major U.S. cities again grew at a pace faster than inflation, according to Circle of Blue’s annual survey of water rates for single-family residential customers. Water prices increased an average of 6.7 percent in these metropolitan areas, a slower rate than in recent years but well above the 2.1 percent increase in the U.S. Bureau of Labor Statistics’ Consumer Price Index for 2012.
