Abstract

The agro-ecosystem is a complex system, with various parameters that can impact on its productivity. Over time, human beings have put the sector under stress due to their demands for food and other agricultural products from it. The proposed Ecological-Footprint Agro-Ecosystem Model (EFAM) has shown that the increasing ecological footprint (i.e. demands on the agro-ecosystem) has a negative relationship with the efficiency of productive arable lands. Agricultural lands are extremely scarce. Additionally, in the present study, data on land used fo agriculture have been converted into global calorie received from the sun which are stored in agricultural products; this shows that land is only marginally producing the calories that human beings need for food security globally. This will lead to economic instability around the world. The policies for agro-ecosystems should monitor the condition of agriculture in the world from climate change to land productivity and good distribution of food throughout the world. This may be done by subsidizing world food production through United Nation programs. In this respect, the UN or governments should have funds reserved to support subsidizing food production in the impacted areas of lower production but without changing the policy for market commodities. This fund is to be used not for emergencies but to support farmers in producing agricultural commodities and to ensure food security.
