Transformation of raw products to end-consumer products
4.
Prevention of adverse environmental effects (e.g. waste management and soil
degradation)
5. Supply
and demand for food in a global basis</span></span>
6. Crop quantity and quality
<span>7. Study of other fields of agriculture (e.g.
soil science) </span>
