By Lester R. Brown As food supplies have tightened, a new geopolitics of food has emerged—a world in which the global competition for land and water is intensifying and each country is fending for itself. We cannot claim that we are unaware of the trends that are undermining our food supply and thus our civilization. We know what we need ...

Denver International Airport (DIA) serves 22 commercial airlines, offering non-stop service to more than 150 destinations worldwide. In 2008, DIA handled over 51,000,000 passengers. With an airport elevation of 5,431 feet and 53 square miles of property, Denver International Airport has a historical reputation for massive snow-fall — at times, even overnight. DIA’s snow removal is ...

When New York City opened registration for its much anticipated public bike-sharing program on April 15, 2013, more than 5,000 people signed up within 30 hours. Eager for access to a fleet of thousands of bicycles, they became Citi Bike members weeks before bikes were expected to be available. Such pent-up demand for more cycling options is on display in cities across the United States—from ...

Throughout most of human existence, population growth has been so slow as to be imperceptible within a single generation. Reaching a global population of 1 billion in 1804 required the entire time since modern humans appeared on the scene. To add the second billion, it took until 1927, just over a century. Thirty-three years later, in 1960, world population reached 3 billion. Then the pace sped ...

Commencing in 2006, Butterfly Conservation started work to create a new large area (>20 hectares) of lowland heathland and acid grassland on existing arable land at Prees Heath Common, Whitchurch, Shropshire. The existing small and fragmented areas of heathland on Prees Heath Common supports the only remaining colony of the Silver-Studded Blue butterfly (Plebeius argus ) in the English ...

Received for publication September 19, 2008. The leaching of soil particles and surface applied 14C-labeled glyphosate and pendimethalin from intact soil columns (height: 50 cm; diameter: 30 cm) were investigated, and the relative significance of particle-facilitated pesticide transport was quantified. Investigations were performed with a recently plowed (four columns) and an untilled (five ...

The use of crop rotation systems involving winter-annual grazing can help peanut (Arachis hypogaea L.) producers increase profitability, although winter-annual grazing could result in excessive soil compaction, which can severely limit yields. We conducted a 3-yr field study on a Dothan loamy sand in southeastern Alabama to develop a conservation tillage system for integrating peanut with ...

There is increasing use of Italian ryegrass (Lolium multiflorum Lam.) as a green manure in potato (Solanum tuberosum L.) rotations; however, effects of its management on soil N supply to the subsequent potato crop are unknown. Fertilizer N management and plow-down date for a preceding Italian ryegrass crop, ‘Lemtal’, on soil N supply to a subsequent potato crop, ‘Russet Burbank’, was determined ...

Reduced tillage results in lower production costs and thus may have economic advantages for farmers. However, yield penalties, specific yield risks, or higher nutrient requirements may counteract the positive effects of reduced tillage. This study investigates long-term tillage effects (moldboard plow, and deep and shallow chisel plow) and their interactions with N fertilizer input on yields and ...

Received for publication December 15, 2008. Long-term effects of tillage intensity, N fertilization, and crop rotation on carbon dioxide (CO2) and methane (CH4) flux from semiarid irrigated soils are poorly understood. We evaluated effects of: (i) tillage intensity [no-till (NT) and conventional moldboard plow tillage (CT)] in a continuous corn rotation; (ii) N fertilization levels [0–246 kg N ...

One of the toughest things for people to do is to anticipate sudden change. Typically we project the future by extrapolating from trends in the past. Much of the time this approach works well. But sometimes it fails spectacularly, and people are simply blindsided by events such as today’s economic crisis. For most of us, the idea that civilization itself could disintegrate probably seems ...

Nitrogen mineralization occurring near the soil surface of agroecosystems determines the quantity of plant-available N, and soil enzymes produced by microorganisms play significant roles in the N mineralization process. Tillage systems may influence soil microbial communities and N mineralization enzymes through alterations in total soil C and N. Soil aggregates of different sizes provide diverse ...

While no-till (NT) cropping systems can provide conservation benefits in the northern Corn Belt, adoption has been low due to concerns about potential yield reductions and economic risk. Strip-tillage (ST) systems have been proposed as an alternative that may provide many of the conservation benefits of NT while maintaining productivity and economic returns. The objectives of this study were to ...

Continuous no-till (NT) results in soil improvements, primarily in the surface 5 cm of soil. One-time tillage may improve NT systems by inverting surface soil with less improved deeper soil. Research was conducted to determine the change in abundance of soil microbial groups after a one-time tillage of NT and their recovery dynamics. Experiments were conducted under rainfed corn (Zea mays L.) or ...

Harvesting corn (Zea mays L.) residue in continuous corn (CC) may require changes in crop management for increased efficiency. Experiments were conducted in Illinois to determine how residue removal and tillage affect surface residue after planting and the response of CC to N fertilization. Partial removal of residue left 21 to 26% surface residue coverage with a chisel plow system, compared with ...

A diversified crop rotation may reduce fertilizer N inputs for corn (Zea mays L.) and increase soil organic C (SOC). Our objectives were to determine the effects of crop rotation and fertilizer N on soil C within the surface soil (0–15-cm depth). Rotations were started in 1990 on a Barnes sandy clay loam near Brookings, SD. Measurements of SOC began in 1996. Primary tillage since 1996 was chisel ...
