Fisheries and aquaculture are important
contributors to food security and livelihoods at household, local, national and
global levels. Today's roundtable on fisheries at the CBD Biodiversity
Conference (COP13) in Cancun highlighted that fish already provide essential
nutrition for 3 billion people and 50 per cent of protein and essential
minerals for 400 million people, mainly in poor countries.
Maria Helena Semedo, Deputy Director General of FAO, addressing the ministerial
roundtable, said that biodiversity conservation is strongly linked to food
security and poverty reduction.
"Aquatic systems are enormously
biodiverse and a key challenge is increasing production while preserving our
natural resources and dealing with climate change impacts," said Semedo.
"We need an integrated approach to restore productive capacity and
ecosystems services of our blue world. Mainstreaming biodiversity means a more
participatory approach where biodiversity conservation is seen as an incentive.
Sustainable management of fisheries should be our common goal and
aspiration."
Fisheries are under high pressure due to human
activities including overexploitation, pollution and habitat change. Climate
change is compounding these pressures, posing very serious challenges and
limiting livelihood opportunities.
For millennia, small-scale fisheries and fish
farmers have drawn on their indigenous knowledge and historical observations to
manage seasonal and climate variability but today the speed and intensity of
environmental change is accelerating, outpacing the ability of human and aquatic
systems to adapt.
"Oceans and other water bodies are
becoming warmer and may affect nutrient recycling and productivity of
fisheries," said Margarita Astralaga, Director of IFAD's Environment and
Climate Division. "Localized extinctions may occur if fish cannot migrate
to cooler waters, for example, in lake fisheries. Fish migration paths could
change, affecting small-scale fishers without suitable vessels to pursue
migratory species. Increased spread of disease, reduced oxygen and increased
risk of toxic algae blooms and fish kills will impact on aquaculture
production."
Sea level rise combined with extreme weather
events, like stronger storms, severely threatens coastal communities and
ecosystems. Higher water tables and drainage problems may affect brackish-water
aquaculture and destruction of fishing and aquaculture assets. There may also be
fish escapes, increasing the risk of disease and parasitic infestation of world stock as
well as impacting biodiversity.
Some lakes, rivers and water bodies are at
risk of drying up. Changes in rainfall patterns and evaporation rates lead to
changes in run-off, water levels, water availability and quality, and
sedimentation patterns in inland and coastal water bodies, affecting the
production of both fresh-water fisheries and aquaculture systems.
"In many cases, it is the poorest communities
in the poorest countries that are most vulnerable to these changes," added
Astralaga.
Fisheries more
than any other modern food production system, depend on the health and natural
productivity of the ecosystems on which they are based. Aquaculture, practised
on a small-scale in rural areas in developing countries, is also dependent on
ecosystem services for feed, seed and adequate supplies of clean water.
"The need to increase
resilience to climate change is required for smallholder agriculture as well as
for small-scale fisheries and aquaculture," said Astralaga, "IFAD
continues to focus on country-led development, community-based natural
resources management, gender equality and women's empowerment, access to
financial services and markets, environmental sustainability and institutional
capacity in the design of its fisheries and aquaculture interventions."
IFAD is integrating climate
adaptation and mitigation in its fisheries and aquaculture operations through
two multiple-benefit approaches namely; the ecosystem approach and
co-management.
Fisheries
and aquaculture are of particular concern to IFAD due to their importance to food and nutrition security; their close relationship with the
environment and natural resources; their contribution to poverty reduction and
employment, often in rural areas of developing countries where alternative
economic opportunities are limited, and for gender equity as women dominate the
post-harvest aspects of fisheries; and small-scale fishers
(including processors) and fish farmers will be among the first to be
significantly impacted by climate change.
Case
studies – IFAD in action
IFAD supported
projects include the Haor Infrastructure and Livelihoods Improvement
Programme (HILIP) started in 2013 to support vulnerable communities in
the Haor Basin in north eastern Bangladesh, an area faced with extreme climate
events including heavy monsoon rains, cyclones, floods, storms and strong
winds.
The basin is
effectively flooded for six months annually, which seriously interrupt economic
activities and their capacity to produce food. The aim of the project is to
improve road infrastructure (i.e. bridges, culverts, canals), build local
capacity and expand access to natural resources, technology and markets. Other
interventions for climate resilience include an early warning system against
adverse climate events, a community-based resource management model in priority
water bodies ensuring communities have fishing rights, excavation of silted
water bodies and establishment of fish sanctuaries and planting swamp trees.
The project will also secure employment for poor rural women under
infrastructure improvement contracts and it will support women's income-generating
activities. Additional financial support has been provided to enhance climate
adaptation and resilience through a complementary project, Climate Adaptation
and Livelihood Improvement Programme (CALIP).
The
Fisheries Resources Management Programme (FRMP) in Eritrea was designed
in 2016 and seriously takes environment and climate change vulnerability
analysis and risk mitigation measures into account. There is one component
addressing coastal ecosystem management through an integrated approach, which
includes mangrove planting and management and inter-sectorial development planning. It will establish a
fisheries monitoring, surveillance and management system to ensure effective
measures such as gear restrictions, closed areas and seasons and adaptation to
eventual changes in the migratory movement patterns of the pelagic fish
species. Solar technologies will be promoted for fish preservation and
processing. Another component will support inland aquaculture through water
reservoirs to increase productive use of the scares water resources in the
country (only reservoirs with low risk of water depletion will be used). Fish
species with high resistance to local climate related stress will be selected.
Finding and applying management approaches that avoid unsustainable
fishing practices and that enable stocks to recover are essential elements in a
strategy to conserve and sustainably use biodiversity. A number of key
strategic actions for accomplishing this, are being explored during COP13.
The overarching principles of sustainable fisheries have been agreed to,
and are stipulated in, a number of international instruments at COP13. These
represent a comprehensive global framework for fisheries policy and management
and support mainstreaming of biodiversity in fisheries and aquaculture.
However, there is a need for the strengthening of fisheries management
agencies, particularly with regard to governance and assessment so that
biodiversity considerations are explicitly part of their work and
accountability, as well as constructive interagency collaboration, and
meaningful participation of biodiversity experts and relevant stakeholders in
the fisheries management process.
Engaging the fishing sector is critical to the successful implementation
of sustainable marine conservation and management measures. The governance of
marine fisheries and the conservation of marine biodiversity continue to
evolve; coherence between them remains critical if each is to achieve its
goals.
Approaches for enhancing the integration of biodiversity and
sustainability of fisheries include:
·
Making greater use of rights-based and innovative
fisheries management systems, such as community co-management, that provide
fishers and local communities with a greater stake in the long-term health of
fish stocks;
·
Eliminating, reforming or phasing out those subsidies
which are contributing to overfishing;
·
Enhancing, in each country, monitoring and enforcement
of regulations to prevent illegal, unregulated and unreported fishing by
flag-vessels;
·
Phasing out fishing practices and gear which cause
serious adverse impacts to the seafloor or to non-target species; and
·
Developing marine protected area networks and other
effective area based conservation measures, including the protection of areas
particularly important for fisheries, such as spawning grounds, and vulnerable
areas;
Appropriate approaches for addressing biodiversity considerations in
fisheries management will be situation-specific and depend greatly on the
capacities and information available. The political will and resources to
enable fisheries management agencies to fully deliver on a mandate to address
fisheries and biodiversity issues is also needed as is enhanced regional
cooperation between fisheries and environmental agencies.
