This lecture, delivered by M.S. Swaminathan, focuses on strategies for ensuring food and water security, addressing issues like water poverty and sustainable agriculture. The speaker discusses pathways for sustainable water security, including supply augmentation, demand management, and harnessing new technologies. Emphasizing the importance of community involvement, the lecture explores innovative approaches like sea water farming and genetic engineering for abiotic stress tolerance. The text highlights the significance of water literacy and the role of communities in ensuring water and food security for all.

Water Poverty Index (Developed by Drs Caroline Sullivan and Jeremy Meigh, Centre for Ecology and Hydrology, Wallingford, UK) Indicators • Available Resource • Access to Water • People’s capacity to afford and organise water supplies • Use of water for domestic, industrial and environmental purposes • Environmental Management (Hydrologic Security)
Water Poverty Source : The World’s Water 2002-2003; Centre for Ecology and Hydrology, World Water Council * 2000 estimate 1 2002
Building a Sustainable Water Security System Pathways • Supply augmentation • Demand management • Quality monitoring and improvement • Harnessing new technologies • Solar desalination • Breeding for abiotic stresses (Mendelian and Molecular approaches) • Bioremediation • Precision farming, fertigation and green house horticulture • Information and Communication technologies for launching a Water Literacy Movement
Low Water Farm Park • Mulching and enhancing the water holding capacity of the soil • Water harvesting • Economic and efficient use of water (drip, sprinkler, etc.) • Cultivation of low water requiring but high nutritive and economic value crops, like pulses, millets, oil seeds, fodder, feed and medicinal plants
Sea Water Farming for Coastal Area Prosperity Sea Water : 97% of Global Water Pool Agriculture : Consumes over 80% of fresh water Components of Action Plan • Mixed cropping of Mangroves, Salicornia and Atriplex • Sustainable capture fisheries • Low external input sustainable aquaculture (shrimp farming) • Market driven off-farm enterprises to improve the population supporting capacity of the ecosystem.

cDNA libraries were constructed from the Mangrove species Avicennia marina • A number of genes with potential application to abiotic stress has been isolated and charactreised • Four isolated genes were used for developing transgenics in rice, Brassica and Vigna Avicennia marina Transgenic plants with salinity tolerance genes

Strengthening Water Security • Undertake eco-restoration of hydrologic hot spots • Develop ground water sanctuaries in chronically drought prone areas • Give priority to Water Saving and Sharing in the Employment Guarantee programme initiated in 150 district
SarvodayaCommunity Co-operation Community is humanity’s most holistic win / win expression of doing more with less. This success-generating context is as true for cities and towns as it is for nations and states. The ultimate understanding of community is that we each have two homes – one we can lock and call our own – the other, having neither doors nor walls, can only be shared.

Monsoon Management Crop Weather Watch Groups Simulation Modelling • Alternative cropping strategies • Seed reserves to implement contingency plans • Rural Climate Managers • Computer-aided knowledge centres
National Monsoon Management Strategy Most Seriously Affected Areas (MSA) Most Favourable Areas (MFA) • Food, water and fodder security • Ground Water Sanctuaries • Crop life saving agronomy • Compensatory production programmes • Production of seeds, feed grains, fodder and fuel wood
Building a Sustainable Water Security System Integrated Strategy – for Today: • Sea Water : Coastal Agro-aqua farms and sea water farming • Sewage and Effluents : Mandatory treatment and recycling • Rain Water : Mandatory harvesting, storage and economic use • Ground Water : Legislation to regard ground water as a public rather than a private resource • Rivers, Lakes, Tanks and Wells : Attention to quality and efficiency • Basic Ground Rule : Conjunctive use of different water sources Attention to Water quality
Water Quality Public Policy and Action • Policy for the safe and responsible use of pesticides • Define Food Security as “physical, economic, ecological and social access to balanced diet and safe drinking water” • Designate one woman and one male member in all grassroot elected bodies as Water Quality Managers

Enhancing our Agricultural Competitiveness Basic Thrusts A. Steps have to be taken to enhance • Sustainabilitythrough conservation and enhancement of the basic life support systems (land, water, forests, biodiversity and the atmosphere). • Productivity through bridging the gap between potential and actual yields. • Quality through awareness of Codex Alimentariusstandards and sanitary and phytosanitary measures. • Incomethrough enhancement of factor productivity, farming system diversification and value addition
Paradigm Shift : Adding the Dimension of Environmental sustainability Green Revolution Ever-green Revolution Commodity Centered and Laboratory Research Integrated Natural Resources Management Centered and Participatory Research with Farm Families
Concept of Ever-green Revolution What nations with small farms and resource poor farmers need is the enhancement of productivity in perpetuity, without associated ecological or social harm. The green revolution should become an ever-green revolution rooted in the principles of ecology, economics and social and gender equity. - M S Swaminathan, 1990
Biotechnology and Organic Agriculture 2) Water Quality 1) Soil Health 3) Plant Health • Bioremediation • Vermiculture • Bio-fertilisers • Stem nodulating green manure crops • Genetic Resistance • Biopesticides Organic Farming 6) Environment 4) Post-harvest Technology • Biomonitoring through Bio-indicators • Higher Carbon Sequestration • New strains with improved keeping, processing and transport qualities 5) Animal Health • Vaccines • High quality feeds and fodder IFOAM : Genetic Engineering is excluded in organic agriculture
