However, concerns have been raised over the sustainability of intensive agriculture. Intensive agriculture has become associated with decreased soil quality in India and Asia, and there has been increased concern over the effects of fertilizers and pesticides on the environment, particularly as population increases and food demand expands. The monocultures typically used in intensive agriculture increase the dedicated hosting number of pests, which are controlled through pesticides. Integrated pest management (IPM), which "has been promoted for decades and has had some notable successes" has not significantly affected the use wireless broadband of pesticides because policies encourage the use of pesticides and IPM is knowledge-intensive.[27] Although the "Green Revolution" significantly increased rice yields in Asia, yield increases have not occurred in the past 15–20 years.[27] The genetic "yield potential" web site design has increased for wheat, but the yield potential for rice has not increased since 1966, and the yield potential for maize has "barely increased in 35 years".[27] It takes a decade or two for herbicide-resistant weeds to emerge, and insects become resistant to insecticides within about a decade.[27] Crop rotation helps to prevent internet marketing resistances.
