  • Arsenic in irrigated paddy soils

    Natural arsenic pollution of drinking water has been reported from over 70 countries world-wide, affecting an estimated 150 million people (Ravenscroft et. al., 2008). About 50 million of these people live in Bangladesh, 30 million in India and 33 million in six other countries of south and south-east Asia. It has recently been recognised that arsenic-contaminated groundwater used for irrigation ...

  • Controversy about agricultural technology lessons from the green revolution

    The development and introduction of transgenically modified organisms to enhance crop and animal production has generated considerable controversy about potential food safety and environmental impacts. The introduction, in tropical Latin America and Asia, of high yielding varieties of wheat, maize and rice beginning in the late 1960s was also controversial. Critics argued that the new technology ...

  • Performance of improved Cassava genotypes for early bulking, disease resistance, and culinary qualities in an inland valley ecosystem

    Cassava (Manihot esculenta Crantz) is commonly grown on residual moisture after rice (Oryza sativa L.) in inland valley swamps (IVS), but not much work has been done to select genotypes that could bulk early, and have high storage root yield in the IVS. Earlier improvement work focused on development of varieties adapted to upland conditions (12-mo cycle), but recently farmers are requesting ...

  • Agricultural innovation and biotechnology development towards sustainable goals: can we make it more pro-poor?

    Agriculture continues to change – driven by innovation and new technology. Genetics and breeding have revolutionised agricultural systems, and the 'Green Revolution', based on higher yielding varieties of dwarf wheat and rice, is arguably the greatest achievement in food crop development. Gene technologies now offer additional opportunities, where new traits improving crop protection ...

  • Grain Yields Starting to Plateau

    By Lester R. Brown From the beginning of agriculture until the mid-twentieth century, growth in the world grain harvest came almost entirely from expanding the cultivated area. Rises in land productivity were too slow to be visible within a single generation. It is only within the last 60 years or so that rising yields have replaced area expansion as the principal source of growth in world grain ...
