The global demand for agricultural crops is increasing and may continue to do so for decades propelled by 3 billion person increase in global population (United Nations’s forecasts considering a medium fertility index (son per woman) and the greatest global per capita incomes expected.
Analyses foresee that the global demand for crop calories (cereals and tubers) would increase by 100% and that for crop (legumes) and animal proteins would increase by 110% from 2005 to 2050.
In the past, the primary solution to food shortages has been to bring more land into agriculture. For example, in the past five decades, while grain production has more than doubled, the amount of land devoted to arable agriculture has globally increased by only about 9%. Today, about 25% of the
global land is under agriculture and no further significant increase is reasonably to be expected in the future. As a consequence, in order to satisfy the dramatic increase in the global demand for food, the most likely scenario is that more food will need to be produced from the same amount of (or even less) land.
Without innovation, the goal of doubling crop yield per arable land surface unit would require dramatic amounts of water, fertilizers, pesticides and fuel-derived energy. Nevertheless, this solution is economically and environmentally unsustainable.
Producing more food from the same area of land reducing at the same time the energy inputs and the environmental impact requires what has been called sustainable intensification.
Sustainable intensive agriculture provides for the development of:
The scientific research is largely active on these topics.
This exhibition will present some examples.
