The environmental impact of agriculture can vary depending on the region as well as the type of agriculture production method that is being used. Listed below are some specific environmental issues in various different regions around the world. Hedgerow removal in the United Kingdom. Soil salinisation, especially in Australia. Phosphate mining ...
Organic farming typically reduces some environmental impact relative to conventional farming, but the scale of reduction can be difficult to quantify and varies depending on farming methods. In some cases, reducing food waste and dietary changes might provide greater benefits. [43]
According to the waste hierarchy, burning agricultural waste for the sake of energy generation is a less environmentally friendly treatment method than recycling or reusing it. Moreover, incineration for energy generation can be done once, while consumer goods (such as paper made from agricultural waste) can be recycled another seven times. [ 26 ]
Each year, the Australian economy loses $20 billion in food waste. This has a crucial environmental impact through the waste of resources used to produce, manufacture, package, and distribute that food. [99] In addition, it is estimated that 7.6 million tonnes of CO 2 is generated by the disposed food in landfills. It is also the cause of odour ...
Agricultural wastewater treatment is a farm management agenda for controlling pollution from confined animal operations and from surface runoff that may be contaminated by chemicals in fertilizer, pesticides, animal slurry, crop residues or irrigation water. Agricultural wastewater treatment is required for continuous confined animal operations ...
Examples of environmental impacts of animal agriculture: Meat production is a main driver of deforestation in Venezuela; Pigs in intensive farming; Testing Australian sheep for exhaled methane production to reduce greenhouse gas emissions from agriculture; Farms often pump their animal waste directly into a large lagoon, which has environmental ...
The United States Agency for International Development's (USAID) global hunger and food security initiative, the Feed the Future project, is addressing food loss and waste. By addressing food loss and waste, greenhouse gas emission mitigation is also addressed. By only focusing on dairy systems of 20 value chains in 12 countries, food loss and ...
Effective recycling programs can significantly reduce the need for virgin materials and the environmental impacts associated with extracting and processing those materials. Product life-cycle analysis (LCA) is a comprehensive method for evaluating the environmental impacts associated with all stages of a product's life.
