Papaya is still considered as a domestic consumption crop.
For example, the adverse ecological impacts of both land conversion to agricultural use and freshwater withdrawals for irrigation will strongly limit the viability of these two traditional approaches to increasing crop production, whereas abundant opportunity exists for optimizing soil water ("green water") availability to and consumption by crops to increase their yields.
So has a shift away from farming for human consumption to crops for biofuels and cattle feed.
But experts say that if biofuels are to make a significant dent in the nation's petroleum consumption, the crops themselves must be improved to provide more energy from an acre.
They imply national and international action to create adequate and efficient storage capacity and a conscious decision to control consumption when crops are good in order to build adequate stocks for the future.
A higher diversity of leafy AIVs encourages consumption of crops which substitute or complement each other in a vegetable recipe.
The first poster (Figure 1) identifies the problem at stake as a growing scarcity of (fresh? unpolluted?) water and frames that problem as a function of water consumption by crops.
Indirectly there may be a risk to human health if antibiotics enter the food chain through the consumption of crops fertilised with antibiotic laden manure or through absorption of antibiotics-contaminated water discharge from ethanol plants.
There is particular interest in antioxidant activity/concentrations, as there is strong scientific evidence for health benefits associated with increased consumption of crops rich in (poly)phenolics and other plant secondary metabolites with antioxidant activity (e.g. carotenoids and vitamins C and E).
All four innovative systems satisfied environmental criteria in terms of N management, pesticide use, energy consumption and crop diversity.
As a result, consumption and crop harvests in the United States have grown to peak levels, and organized crime has accumulated enormous capital, which is used to market drugs and to bribe government officials in and out of the United States.
