ECONOMIC AND ENVIRONMENTAL IMPACT OF VEGETABLE CROPS
This article investigates the economic and environmental effects of the expansion of vegetable crops in the Bardenas irrigation district of Aragon, Spain. The analysis is based on crop production functions, estimated with the EPIC crop growth simulator. The expansion of tomato and pepper in irrigated areas generates an important increase of production value and of net revenue, but it as well increase significantly the inputs demand, water, nitrogen and labour, and pollution by nitrogen. The expansion of drip irrigation in vegetable crops increase the value of production and net revenue, and also reduces drastically the contamination by percolation and leaching.
