Abstract
Based on FAO data on agri-environment worldwide, we choose ten major countries to analyse agrienvironment situation and development worldwide. The results showed that China has the greatest agricultural area, seconded by Australia and USA, and third by Brazil and India. USA is the largest country in arable land area, seconded by India, and third by China. Since earlier 1990s, China has become the largest country in the area of permanent crops, seconded by India. Brazil is the largest country in the annual growth of arable land area, seconded by China, and third by Australia. In the area of permanent meadows and pastures, China grows mostly and seconded by Brazil and third by India. India has the largest harvested area, closely seconded by China, and third by USA. Australia is the most fast growing country in area harvested, seconded by Brazil and third by India. China and India are the two countries with most emissions of agricultural CO2 and equivalents, seconded by Brazil, and third by USA. China grows mostly in emissions of agricultural CO2 and equivalents, seconded by Brazil and India, and followed by Canada and USA. China is the largest country of fertilizers consumption, seconded by India, and third by USA and Brazil. China grows mostly in P and K fertilizers consumption. India holds the No. 1 position in the annual growth of N consumption. In general, China and India have the largest amount of emissions of agricultural CO2 and equivalents and fertilizers consumption. Annual growths of arable land area and permanent meadows and pastures of China are also the highest. Agri-environment of China, India, and Brazil has deteriorated significantly. Agri-environment of Australia seems to be deteriorated in the past years. Agri-environment of European countries is relatively optimistic.
