Proponents of a second Green Revolution generally argue that developing countries should opt for an agroindustrial model that relies on standardized technologies and ever-increasing fertilizer and pesticide use to provide additional food supplies for growing populations and economies. In contrast, a growing number of farmers, NGOs, and analysts propose that instead of this capital- and input-intensive approach, developing countries should favor an agroecological model, which emphasizes biodiversity, recycling of nutrients, synergy among crops, animals, soils, and other biological components, and regeneration and conservation of resources. It is argued here that agroecology—a science that provides ecological principles for the design and management of sustainable and resource-conserving agricultural systems—offers several advantages over the conventional agronomic or agroindustrial approach.
