Environmental Impacts Of Food Production Systems
The use of water for irrigation can change river flows reduce water quality and affect downstream ecosystems. The food system contribute to both food security and health and environmental impacts2 3 3.

Environmental impacts of broad groups of foods per kilocalorie.
Environmental impacts of food production systems. Furthermore it is subject to environmental impacts from other activities. If animals are considered as food production machines these machines turn out to be extremely polluting to have a very high consumption and to be very inefficient. Food production and consumption that have significant impacts on the environment and human health.
Evaluating the environmental impact of various dietary patterns combined with different food production systems Eur J Clin Nutr. And ruminant meat has impacts 100 times those of plant-based foods. As a result declines in wild-caught fish landings threaten nutritionally vulnerable populations.
The primary production of food requires the use of resources such as fuels land water and raw materials that have associated economic and environmental impacts. All food system activities impact the environment. Many of those impacts are intrinsically tied to the use of natural resources.
Eggs dairy pork poultry non-trawling fisheries and non-recirculating aquaculture have intermediate impacts. Habitat loss is one of the leading causes of population declines among wildlife species eventually leading to. Food production may for example have impacts on land degradation deforestation loss of habitats and biodiversity depletion of natural resources and contamination of air soil and waters IPBES 2018.
Converting forest to farmland leads to greenhouse gas emissions as does the use of fossil fuels for energy. Industrialised agricultural production has contributed to climate change oil water and nutrient. Studies have shown that food contributes about 20 to 30 of the total impact of private consumption Tukker et al 2006.
Soil biodiversity in agricultural food production water use and water pollution energy use climate 2. Food production affects the environment in several ways. Some examples of the impact of pork production on the environment.
Environmental impacts of the entire food supply chain Todays food supply chain creates 137 billion metric tons of carbon dioxide equivalents CO 2 eq 26 of anthropogenic GHG emissions. Aquatic foods are a critical source of human nutrition in many developing countries. Food production in agriculture aquaculture can affect the environment by modifying natural habitats wildlife the soil the water and the landscape.
Water stress and desertification is reducing the amount of arable land. Many pests are becoming resistant to insecticides but many of the most. If nothing changes in the way we produce and consume food and in light of the need to increase food production by more than 60 by 2050 FAO 2006 FAO et al 2015 the environmental impacts associated with food production systems will become even more severe and will increasingly surpass the planetary boundaries.
At the same time many other factors are having severe impacts on food production. At the same time these food production systems themselves have a range of negative impacts on the environment. Further for all environmental indicators and nutritional units examined plant-based foods have the lowest environmental impacts.
Environmental Impacts of Food Production First before food production even begins natural habitats and ecosystems are destroyed to clear land that will be used for agriculture. Localization scenarios increased total distances fluid milk traveled by 7-15 overall supply chain costs by 1-2 and emissions of greenhouse gases CO2 equivalent criteria pollutants such as oxides of nitrogen and particulate matter smaller than 25 μm associated with fluid milk transportation by 7-15 per month. The environmental indicators examined are greenhouse gas emissions land.
Below figure gives an illustration on some important environmental consequences that are directly or indirectly affected by the production of pork. In this paper we review the published literature and assess the depth of recent research since 2000 on crop x environment interactions for rice maize sorghummillets sweetpotatoyam and cassava in these two regions.
