Of the many GM organisms around, GM crops have been the subject of much concern about their potentially adverse effects on biodiversity. "The WRI estimates that if people in the U.S. and other heavy meat-eating countries reduced their consumption of beef (and other meat from ruminants) to about 1.5 burgers per person, per week, it would 'nearly eliminate the need for additional agricultural expansion (and associated deforestation), even in a world with 10 billion people.' www.sciencedaily.com/releases/2018/08/180827180741.htm (accessed November 26, 2020). Some Local and Regional Changes of Modern … If current trends continue, but agricultural productivity does not increase beyond 2010 levels, the WRI report concludes that most of the globe's remaining forests would need to be cleared to feed the world.

From agricultural fields, nitrogenous fertilizers leach into the soil and finally contaminate groundwater. Human expansion throughout the world caused that agriculture is a dominant form of land management globally. Given how much land it takes to grow food to feed livestock, meat production is a leading cause of deforestation. Environmentally friendly farming practices used by nearly one third of world's farms: Less developed countries tend to see the largest improvements in productivity. Together, those activities generate about a third of human greenhouse gas emissions, including more than 40% of methane. "Environmentally friendly farming practices used by nearly one third of world's farms: Less developed countries tend to see the largest improvements in productivity." Jules Pretty, Tim G. Benton, Zareen Pervez Bharucha, Lynn V. Dicks, Cornelia Butler Flora, H. Charles J. Godfray, Dave Goulson, Sue Hartley, Nic Lampkin, Carol Morris, Gary Pierzynski, P. V. Vara Prasad, John Reganold, Johan Rockström, Pete Smith, Peter Thorne, Steve Wratten. Global temperatures have already risen about 1 degree Celsius in the past 150 years. The relative significance of farming has dropped steadily since the beginning of industrialization, and in 2006 – for the first time in history – the services sector overtook agriculture as the economic sector employing the most people worldwide. Get the latest science news with ScienceDaily's free email newsletters, updated daily and weekly. The researchers focused on seven different farming changes in which "increases in overall system performance incur no net environmental cost." The topic is very useful in the preparation of competitive examinations like UPSC, SSC, and State Services. Nearly one-third of the world's farms have adopted more environmentally friendly practices while continuing to be productive, according to a global assessment by 17 scientists in five … Reganold helped identify farming systems that meet sustainable intensification guidelines and analyze the data. The new report offers some broad suggestions for how countries might achieve that. Other changes include pasture and forage redesign, trees in agricultural systems, irrigation water management, and conservation agriculture, including the soil-saving no-till technique used in eastern Washington. Sustainable intensification "has been shown to increase productivity, raise system diversity, reduce farmer costs, reduce negative externalities and improve ecosystem services," the researchers write. However, modern irrigation techniques are largely impacting the environment.
