Various commissions have been charged with defining how the new biotechnologies can assist world food production. A World Bank study using leading experts outlined the constraints to agriculture in about 70 percent of their published volume. The remainder was devoted to how the molecular biotechnologies might assist.738 Weeds are not cited as con­ straints to agriculture and thus there are no particular uses for biotechnol­ ogy in their control. A similar study, with similar non-inclusion of weeds as being a problem in agriculture, was published by a consortium of national academies of sciences from the developed and developing world.45
