Green Revolution, Doubly Green Revolution: Technologies, Institutions, and Research for the Agricultures of the Future

For the world's human population to grow from three billion in the 1950s to sic billion at the start of the twenty-first century, agriculture has had to change profoundly. In tropical regions, this deep transformation took the form of the Green Revolution. However, to welcome on the planet an additional three billion humans over the next 50 years, we cannot resort to the same means because they are not viable, either from an ecological or an economic point of view. We must devise a new Green Revolution that pollutes as little as possible and allows us to reduce poverty. Thus, it will be "doubly green" because it will combine productivity and ecological, economic, and social sustainability.
