  • Nitrate leaching and nitrous oxide flux in urban forests and grasslands

    Urban landscapes contain a mix of land-use types with different patterns of nitrogen (N) cycling and export. We measured nitrate (NO3–) leaching and soil:atmosphere nitrous oxide (N2O) flux in four urban grassland and eight forested long-term study plots in the Baltimore, Maryland metropolitan area. We evaluated ancillary controls on these fluxes by measuring soil temperature, moisture, and ...

  • Synthetic nitrogen fertilizers deplete soil nitrogen: a global dilemma for sustainable cereal production

    Received for publication December 19, 2008. Cereal production that now sustains a world population of more than 6.5 billion has tripled during the past 40 yr, concurrent with an increase from 12 to 104 Tg yr–1 of synthetic N applied largely in ammoniacal fertilizers. These fertilizers have been managed as a cost-effective form of insurance against low yields, without regard to the inherent effect ...

  • Profitability maps as an input for site-specific management decision making

    For over a decade, farmers have been collecting site-specific yield data. Many have formed doubts about this investment because of their inability to directly apply this information as feedback for improving management. The objective of this case-study analysis was to investigate how site-specific decisions can be improved by transforming a long-term multiple-crop yield-map dataset into profit ...

  • Creating a Sustainable Food Future: Interim Findings - A menu of solutions to sustainably feed more than 9 billion people by 2050

    The world’s agricultural system faces a great balancing act. To meet different human needs, by 2050 it must simultaneously produce far more food for a population expected to reach about 9.6 billion, provide economic opportunities for the hundreds of millions of rural poor who depend on agriculture for their livelihoods, and reduce environmental impacts, including ecosystem degradation and ...

  • Towards climate-responsible peatlands management

    Peatlands are lands with a naturally accumulated peat layer at their surface. They are found all over the world and come in many forms, display many different characteristics and are used in many different ways. Even though peatlands extend over a relatively small portion of the earth’s land surface, they hold a large pool of carbon. There is no universal definition of peatlands. For the ...

  • Learning from past civilizations

    To understand our current environmental dilemma, it helps to look at earlier civilizations that also got into environmental trouble. Our early twenty-first century civilization is not the first to face the prospect of environmentally induced economic decline. The question is how we will respond. As Jared Diamond points out in his book Collapse, some of the early societies that were in ...

  • How farm policy used to work

    In the period between the 1930s and 1992, farm bills generally instituted compensation policies that took the form of price supports. These policies were designed to manage the surplus production that resulted from centuries of developmental policies while allowing U.S. farmers the chance, with hard work and good management skills, to provide their family with a livelihood. Compensation policies ...

  • Wind turbines cause rising number of bird and bat fatalities

    Wind power is one of the cleanest and safest methods of generating renewable energy. Due to the steady increase in price of nonrenewable sources, wind turbine use has increased 25% in the past decade.i While its growth has helped reduce carbon emissions and pollution, this green source of energy comes at a cost: these massive blades, slicing the air at close to 200 miles per hour, serve as ...

  • Protecting and restoring forests

    Protecting the earth’s nearly 4 billion hectares of remaining forests and replanting those already lost are both essential for restoring the earth’s health, an important foundation for the new economy. Reducing rainfall runoff and the associated flooding and soil erosion, recycling rainfall inland, and restoring aquifer recharge depend on simultaneously reducing pressure on forests and on ...

  • Can the World Feed China?

    By Lester R. Brown Overnight, China has become a leading world grain importer, set to buy a staggering 22 million tons in the 2013–14 trade year, according to the latest U.S. Department of Agriculture projections. As recently as 2006—just eight years ago—China had a grain surplus and was exporting 10 million tons. What caused this dramatic shift? It wasn’t until 20 years ...

  • Global Grain Stocks Drop Dangerously Low as 2012 Consumption Exceeded Production

    The world produced 2,241 million tons of grain in 2012, down 75 million tons or 3 percent from the 2011 record harvest. The drop was largely because of droughts that devastated several major crops—namely corn in the United States (the world’s largest crop) and wheat in Russia, Kazakhstan, Ukraine, and Australia. Each of these countries also is an important exporter. Global grain ...

  • Data Highlight: Arab Grain Imports Rising Rapidly

    The Arab countries in the Middle East and North Africa make up only 5 percent of the world’s population, yet they take in more than 20 percent of the world’s grain exports. Imports to the region have jumped from 30 million tons of grain in 1990 to nearly 70 million tons in 2011. Now imported grain accounts for nearly 60 percent of regional grain consumption. With water scarce, arable ...
