  • 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 ...

  • 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 ...

  • Physical Contaminant Testing Of Composts

    Changes are in progress in multiple countries on weight-based limits for physical contaminants in composts. The net effect may be higher quality compost products. Maintaining and improving compost product quality is vitally important for ensuring continued confidence in organic waste recycling industries around the world. One quality criterion of particular interest from the general ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 3 Ways to Achieve Zero Tropical Deforestation by 2020

    As the crisis of tropical deforestation reaches a new level of urgency due to forest fires raging in Indonesia, an important question is how can the world satisfy the growing demand for forest products while still preserving forest ecosystems? This week, some of the world’s largest companies ...

  • Pacific fisheries need tech to track climate impact

    Climate change could benefit some Pacific fisheries, but tracking the success of adaptation needs effective monitoring, says Johann Bell. Climate change could derail plans by Pacific Island countries and territories (PICTs) to use ...

  • 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 ...

  • Have humans tilted the climate books out of balance?

    In the great book-keeping of climate change, scientists have just discovered a big mistake. They have been wrong, they now think, to count on the mountains, the plains, the forests and the grasslands as an agency that slows climate change by absorbing carbon dioxide. It does absorb carbon dioxide. But the chilling news is that  ...

  • Shrinking forests: The many costs

    In early December 2004, Philippine President Gloria Macapagal Arroyo 'ordered the military and police to crack down on illegal logging, after flash floods and landslides, triggered by rampant deforestation, killed nearly 340 people,' according to news reports. Fifteen years earlier, in 1989, the government of Thailand announced a nationwide ban on tree cutting following severe flooding and the ...

  • Global deforestation is decreasing. Or is it?

    A new look at the complex picture of land use change suggests that when it comes to forests, we’re far from being out of the woods. It started, as many things do, with a rumor. In 2013 Matt Finer, a researcher with the Amazon Conservation Association, heard from locals that someone was cutting down rainforest deep in the Peruvian Amazon, far from prying eyes. So ...
