Overview

•  Fish and food and nutrition security

•  Fish as food

•  Fish, food and nutrition security scenarios in ASEAN

•  Key messages

Fish, food and nutrition security and livelihoods

Fish – producers, value chains, livelihoods

•  Globally,120 million people engaged in capture !sheries and 40 (?) million in aquaculture:

–  90% small-scale (>30% below poverty line)

–  Production generates food and income

–  Value chain employment (e.g. Vietnam, Bangladesh)

–  Women and men

Fish - consumption

•  Fish consumption important in many cultures

•  Main source of animal protein for > 1 billion people

•  Particularly important for the poor

•  Demand globally is growing

Growth in demand for fish – 2007-2015

Availability – ASEAN aquaculture

Cambodia - scenarios show growing fish demand

•  population and wealth driving demand

•  scenario setting for 2030 shows significant new supply required

•  even more aquaculture will be required if capture fisheries are not well managed

•  new investments will be needed to support that

Aquaculture is substituting for declining capture !sheries 1996 2006

Aquaculture is essential, but there are consequences for the fish we eat

Key messages

(1) Fish is important for ASEAN food & nutrition security

•  Fish is a preferred item in the diets of many, especially poor, people

•  It is an important source of quality and highly bioavailable protein, but more importantly of essential fatty acids and micronutrients

—  at key life stages (e.g. the first 1000 days)

—  importance should be measured in relation to consumption of other foods, intra-household food distribution

•  The species we eat are changing, as is the method of production

—  the rise of aquaculture

—  intensification of culture methods

•  Changes impact nutrient content; implications for food and nutrition security

Stability

(2) Increasing availability by aquaculture is important, but is not enough

(3) Gender plays an important role

•  Intra-household assets and food allocation

•  Workloads •  Technologies •  Access to inputs and

knowledge

(4) Emerging lessons from integrating fish, with horticulture systems, and nutrition

•  Integrated systems •  Promotion of nutrition education •  Interventions can improve

income as well as nutrition •  Growing experiences in

Bangladesh and Cambodia with partners (HKI, USAID etc)

Key recommendations

•  Recognize –  value of !sh in human nutrition –  !sh demand will grow

signi!cantly –  wild !sheries and aquaculture

are different and we need interventions in both

–  Aquaculture interventions required for food and nutrition

–  availability is only part of the solution

–  opportunities for better integration of !sheries for human nutrition and health

(1) Dialogue and partnerships

•  Fish has a role, but ensuring positive nutrititional outcomes is about more than !sh supply

•  Inter-sectoral dialogue •  Public, civil society, private

sector partnerships •  Opportunities for sharing of

experiences, within and outside ASEAN

(2) Research – new CGIAR Research Programs

(3) Policy

•  National –  R&D investment that sustain

!sheries and grow aquaculture –  nutrition –oriented investment/

incentives for aquaculture –  value chains and markets –  intersectoral, integrated

interventions based on understanding of pathways to positive nutritional outcomes

•  Regional

–  Fish as an integral part of the ASEAN food and nutrition security framework
