From Green Revolution to Agroecology
The core of life on Earth is the daily requirement of food for people and all living organisms in webs of life, or ecosystems. These natural, self-organising ecosystems, which have provided food for millennia, are increasingly being taken apart - by ecological destruction and changing climates caused by ever increasing world population; industrialisation, including food production using cheap oil; deforestation; and urbanisation - all driven by economic growth and consumerism, and all affecting the health and wellbeing of people and earth. This increasingly puts pressure on food availability and price. Hence food security has become a major global issue and will remain so, especially given ongoing degradation of soils, depleting water resources, peak oil, global warming and a population of nine billion people by 2050.
