  • Keyhole Gardens; Positive Impact on Food Security

    World hunger is a constant problem. It has been one of the most widely discussed topics in recent years. Rapidly increasing global population, limited natural resources, and climatic changes, has resulted in the need for a sustainable increase in food production. Scientists, governments, and organizations across the world are working together to bring innovations and good farming practices which ...

  • Turning field residue into ethanol feedstock

    Darrin Ihnen is looking at corncobs in a new light. Once left on the fields to rot, Ihnen is now harvesting the cobs along with the corn from 4,000-acres on his farm in Hurley, South Dakota - hoping to turn the field waste into income producing feedstock for making ethanol. Typically corn is harvested by a combine that strips the ears from the corn stalks, separates the grain from the ears and ...

  • The problems with the arguments against GM crops

    New evidence shows that arguments against GM crops are unfounded, says Margaret Karembu. The year 2013 marked the 18th consecutive year of commercial cultivation of genetically modified organisms (GMOs) or now commonly referred to as biotech crops. And in just under two decades, the volume of ...

  • Emissions from Crops - POST Note

    Agriculture contributes 9% of the UK’s greenhouse-gas (GHG) emissions burden and 10-12% globally. Although there is a long-term declining trend from UK agriculture, the sector may account for a larger share of overall emissions in the future as other sectors reduce emissions. This POSTnote focuses on reducing GHG emissions from growing and storing arable and horticultural crops. ...

  • Productivity and nutrient dynamics in bioenergy double-cropping systems

    Double-crop systems have the potential to generate additional feedstocks for bioenergy and livestock utilization, and also to reduce NO3–N leaching relative to sole-crop systems. Field studies were conducted near Ames, IA, during 2005–2007 to evaluate productivity and crop and soil nutrient dynamics in three prototypical bioenergy double-crop systems, and in a conventionally managed sole-crop ...

  • Crop sensors outdo farmers at choosing nitrogen rates

    Choosing how much nitrogen (N) to put on corn fields isn’t something farmers take lightly. Many factors go into the decision, including past experiences, the timing of application, yield goals, and results from soil tests. Nevertheless, crop sensors can select N rates for corn that outperform those chosen by farmers, according to more than 50 on-farm demonstration projects conducted in ...

  • One crop, two ways, multiple benefits

    Nitrogen fixation is one of the best examples of cooperation in nature. Soil microbes – naturally occurring bacteria in the soil – work with plants to pull nitrogen from the air. They turn the nitrogen into a form the plant is able to use. In return, the plant lets the microbes eat some of the sugars it makes. Faba beans (also called fava beans) are one example of plants that work ...

  • Accumulation of contaminants of emerging concern in food crops, part two: Plant distribution

    Arid agricultural regions often turn to using treated wastewater (reclaimed water) for irrigation of food crops. Concerns arise, however, when considering the potential for persistent contaminants of emerging concern (CECs) to accumulate into plants intended for human consumption. This work examined the accumulation of a suite of nine CECs into two representative food crops, lettuce and ...

  • Crop gene banks are preserving the future of agriculture. But who’s preserving them?

    As climate change makes crop diversity even more important, gene banks struggle to stay afloat. During the past few years of civil war in Syria, rebel fighters have destroyed Shia mosques and Christian graves, and burned and looted Christian churches while the Islamic State group has demolished priceless artifacts in the region. Nothing seemed sacred to the disparate ...

  • Regional modelling for optimal allocation of agricultural crops considering environmental impacts, housing value and leisure preferences

    Regional planning should consider the impact of agricultural crops on housing value and leisure, as well as on the local environment. We designed an optimisation model for allocating agricultural crops based on farmers' profits as well as the impact on these three factors. Each crop creates a different landscape, as well as a different effect on shading and noise reduction. This in turn ...

  • Marginal value of natural water in agriculture: a study in the suburbs of Mekelle City, Ethiopia

    In areas where markets for natural water are lacking, information on its marginal value can be an important tool for proper pricing to achieve efficient allocation of the resource. This article investigates the marginal value of natural water (rainwater used as a proxy) in agricultural crop production in the suburbs of Mekelle City, Ethiopia, by econometrically estimating individual value ...

  • Dirty droughts causing loss and damage in Northern Burkina Faso

    Extreme droughts in the northern part of Burkina Faso are locally referred to as tundi , meaning ‘dirty weather’, because they severely disrupt people’s livelihoods in the area. This article investigates the loss and damage from the tundi droughts that occurred in 2004 and 2010 in the Sahel Region. The study conducted field survey among households in ten villages. We found ...

  • Family farms can be competitive by focusing on conservation and stewardship

    While the U.S. Department of Agriculture (USDA) reports a 40 percent decline in U.S. cropland soil erosion rates from 1982 to 2007, recent trends appear to challenge this progress. Record prices for corn and soybeans have diverted acres out of conservation programs and encouraged intensive production on a wide scale. Tree lines are cleared and wet areas drained, turning 120-acre farms into ...

  • Corn, a Vital Staple Food in Africa

    Africa contributes the least to global warming than any other continent. However, it suffers greatly from some of the more serious impacts of climate changes. The statistics are shocking: Africa emits roughly 4% of greenhouse gas emissions, while the United States emits 23% of the total global greenhouse gasses. Unfortunately, along with Asia, Africa is the region where crop production is the ...

  • Case study - Guangdong Academy of Agricultural Sciences (GDAAS)

    There are 13 research institutes under the GDAAS, including specific foods and crops and fertilizer research. The main mission of the institution is to carry out non-profit research around agricultural science and techniques.  As one of the most important agricultural crops institutions, the Crops Research Institute has been focusing on the development of new varieties of crops, cultivation ...

  • Better photosynthesis for a better world?

    There’s no question that plants are better than most other life forms at converting carbon dioxide and sunlight into the sugars that form the basis of our global food web — and eventually, humans’ entire food supply. But fact of the matter is, with conversion rates hovering around 2 percent for our best crop fields, they’re by no means great. Even a slight increase in the ...

  • Mining and harnessing natural variation: A little magic

    The success of a breeding program depends on having adequate diversity in the germplasm. However, as advanced breeding stocks and materials are generated, one casualty is the diversity itself. As a result, breeding programs in many crop species have reached a point of diminishing returns and it is feared that unless new diversity is infused into the breeding germplasm, we face catastrophic ...

  • A hotter planet means less on our plates

    In the Sunday November 22, 2009 issue of Outlook in the Washington Post, Lester Brown discusses the significant implications of food security in the upcoming Copenhagen Conference. As the U.N. climate-change conference in Copenhagen approaches, we are in a race between political tipping points and natural ones. Can we cut carbon emissions fast enough to keep the melting of the Greenland ice ...

  • Rethinking food production for a world of eight billion

    The World Food Programme and the Chinese government jointlyannounced that food aid shipments to China would stop at the end of theyear. For a country where a generation ago hundreds of millions of peoplewere chronically hungry, this was a landmark achievement. Not only hasChina ended its dependence on food aid, but almost overnight it has becomethe world’s third largest food aid donor. The key to ...
