  • China’s Rising Soybean Consumption Reshaping Western Agriculture

    Global demand for soybeans has soared in recent decades, with China leading the race. Nearly 60 percent of all soybeans entering international trade today go to China, making it far and away the world’s largest importer. The soybean was domesticated some 3,000 years ago by farmers in eastern China. But it wasn’t until well after World War II that the crop gained agricultural ...

  • Comparing RGB-based vegetation indices with NDVI for agricultural drone imagery

    Abstract Agribotix conducted a post hoc test of two vegetation indices, VARI and TGI, that used only the three visible-band signals from an unmodified CMOS camera. The results were compared to NDVI, which is generally considered to be a reliable measure of field health and the underlying RGB image. While the results are somewhat encouraging in limited cases, it is clear that neither VARI nor ...

  • Estimation of the increase in deforestation due to agricultural and pastoral activities in the Brazilian Western Amazon: an approach based on the relationship between production and productivity

    This paper presents and discusses the evaluation results of the increase in deforestation verified in the period of 1970 to 1990 in the Cruzeiro du Sul area, Acre State, in the Brazilian Western Amazon, based on an analysis of the relationship between the production and the productivity of the agricultural and pastoral (A&P) activities. The analysis suggests a deforestation increase owing to ...

  • Spatial and temporal changes at Tuzla (Palas) Lake in Turkey

    Saline lakes are widespread throughout the arid and semi-arid regions of the world and have considerable ecological importance. They are also very vulnerable to climatic changes or changes in their hydrological regimes. Most saline lakes of Turkey are close to the verge of extinction due to natural and anthropogenic impacts. This study analyzes the spatial and temporal changes at a relatively ...

  • Estimating ground cover of field crops using medium-resolution multispectral satellite imagery

    Remote sensing is useful for estimating plant canopy characteristics, such as leaf area index (LAI) and ground cover (GC). When the source of remote sensing data is medium-resolution satellite imagery, plant canopy characteristics can be estimated for numerous fields within an agricultural region. In this study, a procedure was developed to estimate GC of field crops from medium-resolution ...

  • Land accounts for Europe 1990-2000

    Changes in land cover in Europe reflect modifications in the uses of land, which often compete for the same resource: development of artificial surfaces for housing, transport and economic activities; intensification or extensification of agriculture practices; conversion of natural land to agriculture or farmland abandonment; afforestation or deforestation. Accounting for land cover change in a ...

  • Learning from the Terminator debacle

    Monsanto's 1999 decision not to acquire "sterile seed technology", otherwise known as the "Terminator", was in response to widespread pressure. The technology's commercial potential was "uncertain", and the company's image and share price were taking a beating. Potential international suitors risked being scared off. Few people anywhere could find any redeeming ...

  • The cloud isn`t just for rain anymore

    Precision agriculture has been a key enabling technology to achieve higher yields with lower cost and less environmental impact, while keeping the cost of food fairly stable Has global agricultural productivity increased or decreased in the last 25 years? It has, in fact, more than doubled since 1985. Next to advances in seed genetics, precision agriculture has been a key enabling ...

  • Corn and soybean mapping in the united states using modis time-series data sets

    Monitoring and mapping of U.S. croplands has long been a primary goal of many users of earth observation satellite data. The advantages of using low spatial and high temporal resolution data are (i) increased ability to monitor the phenological change of crop plants, and (ii) the possibility of generating consistent large area crop cover maps. This study investigates the potential of 500-m MODIS ...

  • Many Countries Reaching Diminishing Returns in Fertilizer Use

    When German chemist Justus von Liebig demonstrated in 1847 that the major nutrients that plants removed from the soil could be applied in mineral form, he set the stage for the development of the fertilizer industry and a huge jump in world food production a century later. Growth in food production during the nineteenth century came primarily from expanding cultivated area. It was not until the ...

  • Rising Temperature, Rising Food Prices

    Agriculture as it exists today developed over 11,000 years of rather remarkable climate stability. It has evolved to maximize production within that climate system. Now, suddenly, the climate is changing. With each passing year, the agricultural system is becoming more out of sync with the climate system. In generations past, when there was an extreme weather event, such as a monsoon failure in ...

  • Presence and persistence of wastewater pathogen Escherichia coli O157:H7 in hydroponic reactors of treatment wetland species

    Treatment wetlands (TWs) efficiently remove many pollutants including a several log order reduction of pathogens from influent to effluent; however, there is evidence to suggest that pathogen cells are sequestered in a subsurface wetland and may remain viable months after inoculation. Escherichia coli is a common pathogen in domestic and agricultural wastewater and the O157:H7 strain causes ...

  • Regional-scale assessment of soil salinity in the Red river valley using multi-year MODIS EVI and NDVI

    Received for publication April 15, 2009. The ability to inventory and map soil salinity at regional scales remains a significant challenge to scientists concerned with the salinization of agricultural soils throughout the world. Previous attempts to use satellite or aerial imagery to assess soil salinity have found limited success in part because of the inability of methods to isolate the effects ...

  • 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 ...

  • 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 ...
