Knowra Second Green Revolution Second Green Revolution The Second Green Revolution is a proposed new wave of agricultural productivity gains, emphasizing biotechnology, improved farming methods, and food security, especially in developing countries.
Green Revolution : A mid-twentieth-century increase in crop yields driven by high-yielding varieties, irrigation, fertilizers, and pesticides. The earlier transformation supplies the model—and the criticisms—that proposals for a second wave inherit.
Drought-tolerant maize : Maize varieties bred or engineered to maintain yield under limited water availability. It illustrates how crop improvement could target a major constraint on rain-fed farming.
Agroecology : An approach to agriculture that applies ecological principles to farming systems and food production. It often favors ecological redesign and local knowledge over technology-led intensification.
Agricultural intensification : Increasing agricultural output per unit of land, labor, or other production input. The Second Green Revolution is one proposed form of intensification, with disputed trade-offs.
Agricultural biotechnology : The use of biological techniques to develop crops, livestock, and other agricultural products. Biotechnology is one prominent route proposed for raising yields and strengthening crops.
Marker-assisted selection : A breeding method that uses genetic markers to identify plants carrying desired traits. It can speed crop improvement without requiring genetic engineering.
Organic farming : A farming system that restricts synthetic fertilizers and pesticides and follows defined production standards. Its limits on certain inputs contrast with proposals that rely on modern crop technologies.
Fertilizer use : The application of nutrients to crops to support plant growth and increase yields. Access to fertilizer can raise yields, while overuse can pollute water and degrade ecosystems.
Sustainable agriculture : Agricultural practices that seek to maintain productivity while conserving resources and limiting environmental harm. The proposed wave is often framed around productivity that can endure ecological constraints.
Conservation agriculture : A farming system based on minimal soil disturbance, soil cover, and crop diversification. Its soil and water practices offer productivity gains through changes in farm management.
