The way we produce food and manage land must change radically if humans hope to avoid catastrophic global temperature rise, according to a new report by the United Nations panel on … . Deforestation contributes to global warming, and reversing it will be necessary to avoid catastrophic climate change. However, modern irrigation techniques are largely impacting the environment. How has climate change affected human life? (2018, August 27). A report released last month by the World Resources Institute finds that if current dietary patterns continue, an additional 593 million hectares — which is almost twice the size of India — would be needed to feed the projected 9.8 billion people (the anticipated population) by 2050. It is not intended to provide medical or other professional advice. Proponents of the use of genetic engineering in agriculture … Greenhouse gases from food production create a vicious cycle: As Earth gets hotter, farming gets more difficult in many places, which forces farmers to clear more land to grow food. Genetic engineering may accelerate the damaging effects of agriculture, have the same impact as conventional agriculture… Let's study how the development in the agriculture techniques have impacted the environment and ecosystem. "Climate change, including increases in frequency and intensity of extremes, has adversely impacted food security and terrestrial ecosystems, as well as contributed to desertification and land degradation in many regions," the report's authors write. ScienceDaily. 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 countries. The researchers analyzed farms that use some form of "sustainable intensification," a term for various practices, including organic farming, that use land, water, biodiversity, labor, knowledge and technology to both grow crops and reduce environmental impacts like pesticide pollution, soil erosion, and greenhouse gas emissions. The salinity of the soil is one of the reasons of low productivity just because of the improper management of farm drainage. The researchers focused on seven different farming changes in which "increases in overall system performance incur no net environmental cost." The changes include an advanced form of Integrated Pest Management that involves Farmer Field Schools teaching farmers agroecological practices, such as building the soil, in more than 90 countries. But we forget that if we need food to survive then we need agriculture. Less developed countries tend to see the largest improvements in productivity, while industrialized countries "have tended to see increases in efficiency (lower costs), minimizing harm to ecosystem services, and often some reductions in crop and livestock yields," the authors write. The panel of scientists looked at the climate change effects of agriculture, deforestation and other land use, such as harvesting peat and managing grasslands and wetlands. Human influence on the land is accelerating because of rapid population … Right now, agriculture generates an estimated 25% of annual greenhouse gas emissions, according to the WRI; that's when you combine food production and the land-use changes associated with farming, such as clearing vegetation and plowing.

The impacts of modern agriculture on the Environment are discussed below: The top fertile soil of the farmland is removed due to the excessive water supply. It leads to an increase in the primary productivity of the water body or the 'bloom' of phytoplankton. For example, they document how West Africa farmers have increased yields of maize and cassava; some 100,000 farmers in Cuba increased their productivity 150 percent while cutting their pesticide use by 85 percent. Global temperatures have already risen about 1 degree Celsius in the past 150 years. ScienceDaily. This leads to the loss of nutrient-rich soil that hampered productivity. Large swaths of forest have been cut down in Brazil in recent decades to make room for farming. Modern Farming Methods. At that time, the panel broadly suggested that farmland would need to shrink and forests would need to grow to keep Earth from getting more than 1.5 degrees Celsius hotter than it was in the preindustrial era. Large swaths of forest have been cut down in Brazil in recent decades to make room for farming. It is an art of managing the growth of plants and animals for human use.
