Continuing population and consumption growth will mean that the global demand for food will increase for at least another 40 years. Growing competition for land, water, and energy, in addition to the overexploitation of fisheries, will affect our ability to produce food, as will the urgent requirement to reduce the impact of the food system on the(More)
Despite a significant growth in food production over the past half-century, one of the most important challenges facing society today is how to feed an expected population of some nine billion by the middle of the 20th century. To meet the expected demand for food without significant increases in prices, it has been estimated that we need to produce 70– 100(More)
Although food prices in major world markets are at or near a historical low, there is increasing concern about food security-the ability of the world to provide healthy and environmentally sustainable diets for all its peoples. This article is an introduction to a collection of reviews whose authors were asked to explore the major drivers affecting the food(More)
Increasing concerns about global environmental change and food security have focused attention on the need for environmentally sustainable agriculture. This is agriculture that makes efficient use of natural resources and does not degrade the environmental systems that underpin it, or deplete natural capital stocks. We convened a group of 29 'practitioners'(More)
Lettuce downy mildew caused by Bremia lactucae is the most important disease of lettuce worldwide. Breeding for resistance to this disease is a major priority for most lettuce breeding programs. Many genes and factors for resistance to B. lactucae have been reported by multiple researchers over the past ~50 years. Their nomenclature has not been(More)
Steve McKevitt and Tony Ryan: Project Sunshine – how science can use the sun to fuel and feed the world Agriculture is a human activity that involves the purposeful management of land in order to convert solar energy into chemical energy and provide a range of requirements, most notably food, but also fibre, fuel, dyes and drugs. In their ambitious book, "(More)
We are working to determine the role of the Arabidopsis phytoalexin, camalexin, in protecting the plant from pathogen attack by isolating phytoalexindeficient (pad) mutants in the accession Columbia (Col-0) and examining their response to pathogens. Mutations in PADI, PAD2, and PAD4 caused enhanced susceptibility to the bacterial pathogen Pseudomonas(More)
