Other environmental effects of transport systems include traffic congestion and automobile-oriented urban sprawl, which can consume natural habitat and agricultural lands. By reducing transportation emissions globally, it is predicted that there will be significant positive effects on Earth's air quality, acid rain, smog and climate change. [11]
Agricultural economics is an applied field of economics concerned with the application of economic theory in optimizing the production and distribution of food and fiber products. Agricultural economics began as a branch of economics that specifically dealt with land usage. It focused on maximizing the crop yield while maintaining a good soil ...

The negative impact of agriculture is an old issue that remains a concern even as experts design innovative means to reduce destruction and enhance eco-efficiency. [2] Animal agriculture practices tend to be more environmentally destructive than agricultural practices focused on fruits, vegetables and other biomass. The emissions of ammonia ...
This picture illustrates a variety of transportation systems: public transportation; private vehicle road use; and rail. Transport economics is a branch of economics founded in 1959 by American economist John R. Meyer that deals with the allocation of resources within the transport sector. [1] It has strong links to civil engineering.
Air transport produces 20% of the world's food transport carbon emissions. Rail and sea transport produce 10% each of the world's food transport carbon emissions. Although it was never intended as a complete measure of environmental impact, it has come under attack as an ineffective means of finding the true environmental impact.
