The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. [1] The environmental impact of agriculture varies widely based on practices employed by farmers and by the scale of practice.
Other environmental impacts of transport systems include traffic congestion and automobile-oriented urban sprawl, which can consume natural habitat and agricultural lands. By reducing transport emissions globally, it is predicted that there will be significant positive effects on Earth's air quality, acid rain, smog, and climate change. [6]
Lifecycle analysis, a technique that meshes together a wide range of different environmental criteria including emissions and waste, is a more holistic way of assessing the real environmental impact of the food we eat. The technique accounts for energy input and output involved in the production, processing, packaging and transport of food.
Leaching is an important transport pathway for P losses from agricultural fields in predominantly flat areas with sandy soils or soils prone to preferential flow. [7] As opposed to nitrogen phosphorus does interact with soil particles via adsorption and desorption .
Substantial land-use change contributions to emissions have been made by Latin America, Southeast Asia, Africa, and Pacific Islands. The area of rectangles shows the region's total emissions in 2019. [23] Agriculture contributes to greenhouse gas increases through land use in four main ways: CO 2 releases linked to deforestation
Pollutants from agriculture greatly affect water quality and can be found in lakes, rivers, wetlands, estuaries, and groundwater. Pollutants from farming include sediments, nutrients, pathogens, pesticides, metals, and salts. [1] Animal agriculture has an outsized impact on pollutants that enter the environment.
Sustainable transport is transportation sustainable in terms of their social and environmental impacts. Components for evaluating sustainability include the particular vehicles used for road, water or air transport; the source of energy ; and the infrastructure used to accommodate the transport ( roads , railways , airways , waterways , canals ...
The issues include animal welfare, the efficiency of food production, health risks and the environmental impact (e.g. agricultural pollution and climate change). [11] [12] [13] There are also concerns as to whether intensive animal farming is sustainable in the long-run, given its costs in resources. [14]
