Monitoring & Assessment. What is stream flow and why is it important?
Stream flow, or discharge, is the volume of water that moves over a designated point over a fixed period of time. It is often expressed as cubic feet per second (ft3/sec). The flow of a stream is directly related to the amount of water moving off the watershed into the stream channel. It is affected by weather, increasing during rainstorms and decreasing during dry periods. It also changes during different seasons of the year, decreasing during the summer months when evaporation rates are high and shoreline vegetation is actively growing and removing water from the ground.

Water Data - The World's Water. Datasets. Data setsA major goal of our research group is to develop an improved understanding of human land use activities at continental to global scales.
Consequently, we have been developing maps and datasets describing contemporary and historical global land use practices. You may freely download our data sets here, for non-commerical use. Some data sets were developed earlier, during Navin Ramankutty's tenure at SAGE, at the University of Wisconsin. Food Emissions - Big Facts. Big Facts is a resource of the most up-to-date and robust facts relevant to the nexus of climate change, agriculture and food security.
It is intended to provide a credible and reliable platform for fact checking amid the range of claims that appear in reports, advocacy materials and other sources. Full sources are supplied for all facts and figures and all content has gone through a process of peer review. CIMMYT International Maize and Wheat Improvement Center.

The event highlighted the use of Water Funds as an effective option for green development and an example of how governments, financial institutions, businesses, communities and conservationists can work together to protect nature and help build strong and sustainable local economies.
The Coca-Cola Company Latin Center and local Coca-Cola bottlers like Coca-Cola FEMSA, alongside with the environmental organization The Nature Conservancy, have teamed up with the Latin American Water Funds Partnership to protect and restore watersheds in Colombia, Costa Rica, Ecuador, Guatemala, Panama, the Dominican Republic and Venezuela. The model consists of a fund whose returns are invested in conservation actions to improve the health of watersheds and their ability to capture and improve water quality in the long term.

Productivity is a ratio between a unit of output and a unit of input.
Here, the term water productivity is used exclusively to denote the amount or value of product over volume or value of water depleted or diverted. The value of the product might be expressed in different terms (biomass, grain, money). For example, the so-called ‘crop per drop’ approach focuses on the amount of product per unit of water. Another approach considers differences in the nutritional values of different crops, or that the same quantity of one crop feeds more people than the same quantity of another crop.

Credit: Shelly Kittleson/IPS. - Heavy reliance on water intensive crops, a major upstream dam project for the Nile basin, and rising groundwater levels pushing at pharaoh-era monuments will be pressing issues for the next Egyptian president – whether military or civilian. The minister said he expected this amount to decrease to 370 cubic metres by 2050 due to a rapidly growing population. GIS Climate Change Scenarios. 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. Water from an open water surface escapes as vapour to the atmosphere during the day. UN Comtrade. 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. The Saudi programme is an example of a powerful but contentious trend sweeping the poor world: countries that export capital but import food are outsourcing farm production to countries that need capital but have land to spare.

HarvestChoice uses a so-called meso-scale spatial grid typically at 10km or 5-arc minute resolution. Arc-minute? Many of spatial datasets that HarvestChoice is generating are based on grids (we sometimes call it "meso-scale") at three different resolutions - 60 arc-minute (1 degree), 30 arc-minute (0.5 degree), and 5 arc-minute (0.08333333333... degree). We will spare the definition of arc-minute here. Welcome To NWDA. Waterfootprint.org: Water footprint and virtual water. Actualités du CEPII. Waterfootprint.org: Water footprint and virtual water.

Infographic: Price of Water in 30 Major U.S. Cities (2010-2015) Cities raise rates to pay for repairs and to respond to conservation.
The average price of residential water increased by 6 percent between 2014 and 2015, according to Circle of Blue’s comparison of water rates for 20 of the largest U.S. cities and 10 regional representatives. Prices have climbed by 41 percent since 2010. Both figures are for a family of four using 380 liters (100 gallons) per person per day. The price of a monthly water bill varies greatly across the United States, depending more on the condition of infrastructure and on the types of rates that are charged than on water availability or climate. « Les Californiens doivent comprendre que la période d’abondance de l’eau a disparu » The Future of Desalination in California is Still in the Future: California, Israel, and Australia – Significant Figures by Peter Gleick. It’s only natural that during a crisis we look to single, “silver bullet” technical solutions, after all, they are supposed to be effective against werewolves, witches, and other monsters.
For monsters like the ongoing severe California drought, the current favorite silver bullet is seawater desalination. And why not?
Explicit cookie consent. CALIFORNIA is no longer taking a laid-back approach to drought. On April 1st, for the first time, the Golden State imposed mandatory curbs on water use. Governor Jerry Brown ordered 400 local water-supply agencies, which serve 90% of residents, to deliver 25% less over the coming year.
