Drivers of change

Increasing demand for food and energy is primarily driven by a larger and wealthier global population.

The global population is projected to grow with 2.2 billion people, between 2010 and 2050, predominantly in urban areas. The global economy is projected to continue to grow along historical rates, with the highest growth rates in developing countries. As a result, both global agricultural production and energy production have to increase by about 60-70% , leading to increasing agricultural land use and greenhouse gas emissions.
