  • One-Quarter of World’s Agriculture Grows in Highly Water-Stressed Areas

    All living creatures need two things to survive: food and water. A new WRI analysis shows just how much tension exists between those two essential resources. A new interactive map from WRI’s Aqueduct project reveals that more than 25 percent of the ...

  • Aquacrop—the FAO crop model to simulate yield response to water

    This article introduces the FAO crop model AquaCrop. It simulates attainable yields of major herbaceous crops as a function of water consumption under rainfed, supplemental, deficit, and full irrigation conditions. The growth engine of AquaCrop is water-driven, in that transpiration is calculated first and translated into biomass using a conservative, crop-specific parameter: the biomass water ...

  • Measurement of photosynthetic performance in crop plants under South African climatic conditions

    A key objective of the research conducted by Dr Riekert van Heerden (riekert.vanheerden@nwu.ac.za) at North-West University, Potchefstroom, South Africa and Drs Kobie de Ronde (and team members) and Joseph Asiwe at the Agricultural Research Council (ARC–Vegetable and Ornamental Plant Institute & ARC–Grain Crop Institute) is to increase the production of crops important for the ...

  • Fitting germplasm types of tall fescue and orchardgrass to different cropping environments of the mediterranean region

    Understanding of adaptation targets, selection environments, genetic resources, and plant types is required in breeding tall fescue [Lolium arundinaceum (Schreb.) S.J. Darbysh.] and orchardgrass (Dactylis glomerata L.) for Mediterranean environments prone to drought stress. Fourth-year forage yield of seven orchardgrass and five fescue cultivars grown in Algeria and Sardinia revealed (i) ...

  • A weekly operational planning model for a run-off-the-river system: some simulation results from the Tambiraparani river, Tamil Nadu, India

    In the present study, a weekly operational planning model has been developed using a simulation technique for the Tambiraparani river system in Tamil Nadu, India. A planning model has been developed incorporating the important features of the existing operational policy. Paddy is the main crop cultivated in three seasons, although banana is cultivated to an appreciable extent, it has not been ...

  • Productivity of ephemeral headwater riparian forests impacted by sedimentation in the southeastern United States coastal plain

    Received for publication April 30, 2008. Riparian forests serve an essential function in improving water quality through the filtering of sediments and nutrients from surface runoff. However, little is known about the impact of sediment deposition on productivity of riparian forests. Sediment inputs may act as a subsidy to forest productivity by providing additional nutrients for plant uptake or ...

  • Climate Smart Agriculture: Zambia’s Strategy to Reduce Emissions

    The agricultural sector is believed to be the backbone of the Zambian economy thereby alleviating problems associated with poverty and food security. The development of the sector is viewed as one sustainable way of economic growth and ‘Eradicating Extreme Poverty and Hunger’ which is goal number one of the Millennium Development Goals (UN, 2000). The sector contributes to the growth ...

  • How green was my Vertical Farm?

    By 2050, 80% of the earth’s population will live in cities and 3 billion more people will need to be fed. The simple fact is we are running out of available land to grow enough food to feed them. If we can’t grow our cities outward to find more arable land, the only solution is to grow them upwards. This may change the way we design cities forever.The problem is real and immediate. Even by most ...

  • Compost Users Forum: The Applied Thoughts Of A Compost Theorist

    WITHIN a 60-mile radius of my office here in central California, there are 1,000 dairies — each having an average of 2,000 cows. They generate over four million tons of manure annually, so we are pretty much in the manure business whether we want to be or not. Somebody has to manage this material and help the farmers utilize it properly, fulfilling its potential monetary value. That’s what we ...

  • Losing Soil

    In 1938, Walter Lowdermilk, a senior official in the Soil Conservation Service of the U.S. Department of Agriculture, traveled abroad to look at lands that had been cultivated for thousands of years, seeking to learn how these older civilizations had coped with soil erosion. He found that some had managed their land well, maintaining its fertility over long stretches of history, and were ...

  • Could food shortages bring down civilization?

    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 ...

  • Chicago Council lists three-decade changes in greenhouse gases and average temperature

    In 2011, we wrote a column, “Global warming is happening: How should farmers respond?” (http://agpolicy.org/weekcol/549.html). In that column we began by saying, “There was a time when one could legitimately argue that there was a lack of scientific agreement over the issue of the role of humans in global warming and even whether we were in a ...

  • Impact of Agri-environment measures

    The application of agri-environment contracts concerning 1 farmer in every 7 and delivering environmental services over 20% of European farmland, marks a very significant step towards sustainability. The target set in the 5th Environmental Action Programme of 15% coverage by 2000 has thus already been exceeded. The requirement on Member States to apply the regulation throughout their territories ...

  • Seasteading could be the answer to sustainably feeding 9 billion people

    Self-sufficient nation states in the middle of the ocean might be our ticket to a sustainable future. Oceans cover 71 percent of Earth’s surface, yet provide less than 2 percent of the food we eat. The growing demand for seafood, however — predicted to rise to 8 percent during the next decade — from an already depleted and exhausted ocean is forcing ...
