Global food security is one of the most unrelenting issues for humanity, and agricultural production is not sufficient in accomplishing this. However, earlier analyses of agricultural food production barely ever bring out the contrasts associated with economic development and different climatic zones. The world population is increasing day by day and climate change will be causing more extreme weather, higher temperatures and changed precipitation. The crop contributes about 20 % of the total dietary calories and proteins globally. There is 1% annual growth in food demand in the developing regions. The developing regions (including China and Central Asia) account for roughly 53 % of the total harvested area and 50 % of the production. Although, unmatched productivity growth from the Green Revolution since the 1960s dramatically transformed world food production, benefitting both producers and consumers through low production costs and low food prices. One of the key challenges today is to replace today’s food system with new ones for better sustainability. While the Green Revolution freed essential ecosystems from conversion to agriculture, it also created its own ecological problems. Moreover productivity increase is now slow or stagnant. Attaining the productivity gains needed to ensure food security will therefore require more than a repeat performance of the Green Revolution of the past. Future demand will need to be achieved through sustainable intensification that combines better crop resistance plants, adaptation to warmer climates, and less use of water, fuel, fertilizer, and labor. Meeting these challenges will require concerted efforts in research and innovation to develop and set up feasible solutions. Necessary investment will be required to realize sustainable productivity growth through better technologies and policy and institutional innovations that facilitate farmer adoption and adaptation. The persistent lessons from the Green Revolution and the recent efforts for sustainable escalation of food systems in South Asia and other developing nations will definitely providing useful insights for the future.
