Contribution of Aquaculture to Food Security Globally Modadugu V Gupta
The greatest disease of all humankind is “hunger” • Global population from 1.5 billion in 1900 to 7 billion now and to 9 billion by the year 2050; may reach 10 billion • Estimated 925 million under nourished • Micronutrient deficiencies affecting > 2 billion • 250 million children at risk of vitamin A deficiency; equal number suffer from deficiency of minerals (iron, zinc, calcium, etc.) • MDG target of reducing hunger by half by 2015; under nourished declined from 20% of population to 16% in 2010; but no decline in absolute numbers
Poverty and Food Insecurity • Food security; not just producing food, but also access to food • Food security linked with poverty and rural development • Economic access to food ONLY when households generate sufficient income • Aquaculture provides primary source of income • Aquaculture can be a starting point for alleviation of poverty in rural areas
Contribution of Fish to Nutrition • Fish “Rich food for Poor”; cheapest animal protein • Provides over 20% of animal protein to 2.6 billion people globally; in developed countries 13%, while in developing countries > 30% • Major source of animal protein in regions where animal protein in diets is below world average • Provides at least half of animal protein intake for 400 million poor in S. Asia & Africa • Rich source of protein, essential fatty acids, vitamins and minerals. Some fish high in calcium, zinc, vitamin A and iron

Contribution to Livelihood • Globally over 540 million (8% of population) involved in fisheries & aquaculture; growth more than population & employment in traditional agriculture • Fisheries and Aquaculture provides primary source of income • 80-100% of rural aquaculture products sold generating cash for families • Cash generated used for buying other necessities • Brings in foreign exchange
Economic Importance of Fish • Fish most internationally traded commodity; About 40% global production enters international • trade against 10% for meat • Global trade in fish over $ 102 billion in 2008 • Exports of fish & products exceed those of meat, dairy, cereals, sugar, coffee, oilseeds, etc. • In many developing countries foreign exchange from fish exports finances other food imports
Demand for Fish • Present global production of food fish 115 million tons • Demand for fish increased at twice population growth over last 50 years • Estimated additional 20-30 million tons required to meet demand by 2020; could be an underestimate • Per capita consumption increased from 11.5kg in 1970 to 12.5kg in 1980 to 14.4kg in 1990 to 17.0kg in 2008

Aquaculture Importance • Aquaculture fastest growing agriculture commodity with annual growth of >6% in last two decades • Increased from <1 million tons in 1950 to 55 million tons in 2009 • 80% comes from 20 million small-holder farms (<2ha) in developing countries; • Environmental demands for unit biomass or protein produced are lower as compared to poultry , piggery and beef • Grain needed for production of 1kg protein of fish: <13kg; pork 38kg; beef 61kg • Animal protein with small carbon footprint. : 0.96% of total Co2 emission; 6.3-7.5% of agriculture emission
Prevalence of iron and vitamin A deficiency • Cambodia: WFP promoting Esomuslongimanus to supplement iron for small children • Bangladesh: 1.3 million ponds; 10 kg/pond Amblypharyngodonmola can meet vitamin ‘A’ requirement of 2 million children
Breakthroughs in research & development domestication of more species, 72 sps. in 1950 to 336 sps. in 2006 Better aquatic animal health management • Increasing demand – domestic & export • Improvement in policies & governance
Regional importance • Asia-Pacific dominance; over 60% from freshwater • China: 61.5% • Rest of Asia: 29.5% • Europe: 3.6%; mostly high value marine, commercial; research & development remarkable • S. America: 2.2%; commercial & industrial; opportunities for small-scale aquaculture development • North America: 1.5% – finfish & shellfish development • Africa: 1.4%; small-scale & commercial; slower development; gaining importance; increased by 56% during 2003-2007; expansion of small-scale aquaculture

Mariculture • Fastest growing subsector of aquaculture • Of 202 maritime countries and territories, 93 with mariculture in 2004-2008; 15 countries account 96% global production • Caters to high end markets • Breeding technologies developed for more species; moving from wild caught seed to hatchery produced seed • High growth potential
Ornamental fish farming • $ 5 billion market • $ 15 billion industry • Seaweeds farming • $ 5-6 billion market • Pearl farming Farming of non-food species
Women and Aquaculture • Strong relationship between hunger and gender inequality • Equalising women status with men in S. Asia and SS Africa estimated to reduce malnourished children by 13.4 and 1.3 million respectively • Women mostly involved in processing and marketing • Excellent opportunities for involvement of women in aquaculture production • Many success stories – increase in household incomes, better nutrition and health for family

Challenges • Impact of declining water and land resources • Impact of climate change • Impact of intensification and spatial concentration of farms • Increased aquatic animal health concerns • Protecting environment • Sustaining production and livelihoods
Action needed to increase contribution of aquaculture to food security • Strengthen research including fish health management; farmed sps. increased from 72 in 1950 to 336 sps. in 2006 • Integrate small-scale aquaculture into globalised market economy (improving market access, horizontal & vertical linkages, developing business models, etc.) • Species adaptable to climate change; genetic improvement • Integrated water resource management • Introduction of BMPs • Ecosystem approach to aquaculture • Food safety and product quality • Improvements in policies and governance
Conclusion • Aquaculture has shown resilience to various economic crises in the last decade • While precise data not available, available information indicate, contribution of aquaculture to poverty alleviation, food security, employment, trade & gender opportunities is on the increase • Long term sustainability of aquaculture- economic, social & environmental and contribution to food security depends on commitment of governments and good governance
