According to a United Nations Food and Agriculture Organization estimate, about 795 million people suffered from chronic undernourishment in 2015 (FAO, IFAD and WFP 2015), indicating that one in nine people is deficient in calories, protein, iron, iodine or vitamin A, B, C or D, or any combination thereof (Sommer and West 1996). Such high levels of global food insecurity make many human societies vulnerable to health problems, reduced productivity and geopolitical unrest. A crop loss due to pest activity is a major contributor to food insecurity: 30-40% of potential world crop production is destroyed by pests (Natural Resources Institute 1992; Oerke et al. 1994). Of all pests, insects cause an estimated 14% of crop losses, plant pathogens 13% and weeds 13% (Pimentel 2007). An additional 30% of the crop is destroyed by postharvest insect pests and diseases, particularly in the developing world (Kumar 1984).
Humans have probably struggled with pestiferous insects, mites, nematodes, plant pathogens, weeds and vertebrates since the dawn of agriculture some 10?000?years ago (Figure 1.1). The earliest approaches employed were probably hand removal of pests and weeds, scaring away seed-consuming birds and trapping of granivorous rodents. Crop rotation, intercropping and selection of pest-resistant cultivars soon followed. The earliest recorded use of chemical pesticides dates back to 2500 BC, when the Sumerians used sulphur compounds as insecticides (see Figure 1.1). The use of botanical compounds, such as nicotine and pyrethrum, was later reported. However, pesticide application became common practice only in the 19th century, with increased agricultural mechanization.
Figure 1.1 The history of pest management and changes in agro-ecosystem sustainability. Historic data are based on Abrol and Shankar (2012) and https://courses.cit.cornell.edu/ipm444/lec-notes/extra/ipm-history.html.
In the 20th century, the discovery of synthetic compounds with insecticidal and herbicidal properties, such as DDT and 2,4-D in 1939 and 1940, respectively, quickly made chemical control the predominant method of pest control. In most cropping systems, this has remained the case to this day, in spite of growing awareness of the negative impacts of pesticides on human health and the environment. In fact, many of our current serious pest problems have been brought about by intensification of cropping systems, mechanization, selection for high yielding but pest-susceptible crop genotypes, fertilization and irrigation inputs, and frequent application of pesticides (Thomas 1999; Waage 1993). Therefore, since the middle of the 20th century, most pest control measures have targeted specific pests on particular crops within single fields. Although reliance on a single tactic, usually the application of chemical pesticides, provides only a short-term solution (Thomas 1999), such a bottom-up approach has remained dominant is spite of widespread promotion of Integrated Pest Management (IPM) (Ehler 2006).
Integrated Pest Management has been accepted worldwide as the strategy of choice for pest population management. Since the United Nations Conference on the Environment in 1992 in Rio de Janeiro, Brazil, it has been the global policy in agriculture, natural resource management and trade. As a result, most of the world's population now lives in countries with IPM-guided policies for the production of most of the world's staple foods (Vreysen et al. 2007). Nonetheless, the definition of IPM has remained vague and highly inconsistent for more than 55 years (Table 1.1) (Bajwa and Kogan 2002). Van den Bosch and Stern (1962) stated that 'it is the entire ecosystem and its components that are of primary concern and not a particular pest'. Yet only 24% (16 of 67) of IPM definitions surveyed by Bajwa and Kogan (2002) included the term 'system' as the implementable programme or ecological unit. Furthermore, none of the surveyed definitions presented the term 'integrated' (in IPM) to indicate the integration of different measures employed simultaneously against several taxa across pest types (plant pathogens, insects, mites, nematodes, weeds, etc.). Since IPM is not legislatively defined, its definitions seem to reflect the respective interests and points of view of different individuals and organizations. Therefore, IPM is not a distinct, well-defined crop production strategy.
