Biodiversity conservation, sustainable food security and green economy are very closely linked and there is an urgent need to use this three pronged approach to meet the challenges to biodiversity management. The terms ‘green economy’ and ‘food security’ are often used very broadly, therefore, for easy comprehension; green economy refers to enhancing economic growth in perpetuity, without associated ecological and/or social harm. Food Security refers to physical, economic and social access to balanced diet, clean drinking water, sanitation and primary health care for every child, woman and man. The food insecurity atlas developed jointly by M.S. Swaminathan Research Foundation (MSSRF) and World Food Programme (WFP) is an Awareness–Analyses and Action plan document that ranks all the different states in the country, on the above mentioned parameters. Food security basically has 3 components: the first is food availability, which depends on food production and imports. The second is food access, which depends on purchasing power and employment opportunities. The third, food absorption, is a function of safe drinking water, environmental hygiene, primary health care and education. The path towards sustainable development varies from state to state, those with a strong natural resource base ranked high in sustainability but did not produce enough food. Some of the findings reported were to remove pressure on land and water and conserve natural resources for sustainable water supply in Tamil Nadu; increase land productivity, diversify agriculture, improve infrastructure and provide market linkages in Orissa, and to some extent in Bihar and Uttar Pradesh. In states like Bihar and Uttar Pradesh, population stabilization holds the key to sustainable food security. More than 50 % of India’s currently favourable high potential wheat production area may get re-classified as heat stressed, lower potential, short season growing environment. International Food Policy Research Institute (IFPRI) has reported that there will be a fall in wheat production in south Asia by almost 45 million tonnes by 2050 if adequate, adaptive measures are not practiced. The projections for wheat production losses in India by 2050 are estimated to be 6 million tonnes per year or 1.3 billion USD at current prices, due to rise in mean temperature by 1–2 C. There is an urgent need to bring about a transformational change such as the Green Revolution in 1968 which worked like a symphony between technology, services, public policy and farmer’s enthusiasm. There have been timely early warning signals given to policy makers on sustaining food production by shunning the practice of exploitative agriculture involving indiscriminate use of pesticides, fungicides, herbicides; rampant over use of water resources and loss of biodiversity as locally adapted varieties get replaced by high yielding crops. Current lifestyles and extensive consumption of natural resources have expanded the ecological footprint and is a major threat to food security as the human demand to the biosphere services has more than doubled since 1961. An ever green revolution has become essential which primarily aims at increased agricultural production in perpetuity, without associated ecological harm. A combination of green agriculture, organic cultivation practices with integrated pest management and nutrient supply and natural resource management is important for the country. India being an agricultural-based economy, if farm ecology and economics go wrong, nothing else will go right. There is need to integrate farm and mainstream technology into M. S. Swaminathan (&) M.
