Predicting precipitation on nonpoint source pollutant exports in the source area of the Liao River, China
The source area of the Liao River is an important grain growing area in China which experiences serious problems with agricultural nonpoint source pollution (NPS) which is impacting the regional economy and society. In order to address the water quality issues it is necessary to understand the spatial distribution of NPS in the Liao River source area. This issue has been investigated by ...

Robust method for estimating grain yield in western Kenya during the growing seasons
Uncertainties caused by climate change and population explosion require suitable methods for estimating grain yield during the growing seasons. This paper evaluates the applicability of the AquaCrop model in the region of western Kenya. The objectives of the study were to: simulate the long-term maize crop yields for the region using AquaCrop model for variable climate scenarios, and estimate ...

Building a baked anode material with PFC - Case Study
Project Description A baked anode is made of a complex material, obtained by mixing and baking different petrol coke grains, with different size distributions, with a pitch. Hydro PMT needs to study how cracks propagate in such a material – both within and between grains. Representing properly the non-spherical grain shapes, as well as the porosity, both between grains and within the coke ...

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 ...

How technology helps improve animal feed quality and efficiency
In the age of technology, technology touches everything, even in agricultural settings and situations. Technology in recent years has been used to make things like swine production more efficient, building better livestock facilities with new capabilities, and even in growing the grain necessary for sustaining livestock raising. Technology also has a major hand in improving the quality and ...

Bumper 2011 Grain Harvest Fails to Rebuild Global Stocks
The world’s farmers produced more grain in 2011 than ever before. Estimates from the U.S. Department of Agriculture show the global grain harvest coming in at 2,295 million tons, up 53 million tons from the previous record in 2009. Consumption grew by 90 million tons over the same period to 2,280 million tons. Yet with global grain production actually falling short of consumption in 7 ...

U.S.-India: Dealing With Monsoon Failure
The scene plays out in India. At a reception, I met the head of Indian operations for Esso (now ExxonMobil). When I asked him how business was, he said it was great. In particular, diesel sales to fuel irrigation pumps were nearly double the previous year’s level. Why? Because farmers were pumping continuously to try to save their crops. Soon after, I met an embassy staff person, an avid ...

Determination of a critical nitrogen dilution curve for spring wheat
Plant-based diagnostic tools of N deficiency can be based on the concept of critical N dilution curves describing whole-plant critical N concentration (Nc; g kg–1 of dry matter [DM]) as a function of shoot biomass (W; Mg DM ha–1). This has been tested for several crops, including winter wheat (Triticum aestivum L.) but has not been tested for spring wheat. Our objectives were to determine a ...

Capabilities of four novel warm-season legumes in the southern great plains: Grain production and quality
Grain legumes could serve as a low cost nitrogen (N) and energy source for animal production in the southern Great Plains (SGP). This study evaluated the yield and nutritive value of grains of tropical annual legumes novel to the SGP. Included were cultivars of pigeon pea [Cajanus cajan (L.) Millsp.] (cv. GA-2), guar [Cyamopsis tetragonoloba (L.) Taub.] (cv. Kinman), cowpea [Vigna unguiculata ...

Why We Launched Indigo Marketplace
The system by which we grow and distribute grain is well over a hundred years old. In the early 1900s, with significant urban migration, came the need for an efficient way to transport crops from rural areas to city centers. This led to the development of a commodity system, in which growers brought their harvested grain to silos where it was mixed with their neighbors’. Growers were paid a ...

A Saline Duper Wheat that Tolerates Higher Salt Concentrations!
In the past few decades, agricultural land has been largely lost, and increased salinity in soils around the world has received much attention. Nowadays, nearly 8% of the world's arable land can no longer be used for crop cultivation due to salt pollution, and more than half of the world's countries are affected. Wheat is the second largest grain grown after corn and grows more on Earth than any ...

Moving Up the Food Chain
For most of the time that human beings have walked the earth, we lived as hunter-gatherers. The share of the human diet that came from hunting versus gathering varied with geographic location, hunting skills, and the season of the year. During the northern hemisphere winter, for instance, when there was little food to gather, people there depended heavily on hunting for survival. Our long history ...

New Era of Food Scarcity Echoes Collapsed Civilizations
The world is in transition from an era of food abundance to one of scarcity. Over the last decade, world grain reserves have fallen by one third. World food prices have more than doubled, triggering a worldwide land rush and ushering in a new geopolitics of food. Food is the new oil. Land is the new gold. This new era is one of rising food prices and spreading hunger. On the demand side of the ...

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 ...

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 ...
