Pesca predatória desperdiça 50 bilhões de dólares

Estudo do Banco Mundial e da FAO alerta que frota pesqueira joga fora recursos marinhos

As frotas pesqueiras de todo o mundo desperdiçam bilhões de dólares por explorar excessivamente espécies já à beira do esgotamento e por mau gerenciamento. O alerta está num relatório do Banco Mundial e do Fundo Mundial para a Alimentação e a Agricultura (FAO). Os autores do estudo calculam o prejuízo em cerca de US$ 50 bilhões. Do O Globo, 10/10/2008, com informações complementares do EcoDebate.

A chamada sobrepesca já é uma dos maiores ameaças à biodiversidade marinha. Calculase que a maioria das espécies de grande valor comercial, como o atum e o bacalhau, estejam perto de não conseguir recuperar mais suas populações.

Aproximadamente um terço da população das espécies de peixes de valor comercial foi drasticamente reduzido.

Há exemplos de colapso total.

O mais dramático é o desaparecimento do bacalhau da costa leste do Canadá.

Peixes podem desaparecer do cardápio em 50 anos Uma pesquisa publicada na “Science” este ano alertou que se a pesca descontrolada continuar no mesmo ritmo não haverá mais populações viáveis de peixes dentro de meio século. Isso seria o fim da pesca no mundo.

O relatório foi lançado em Nova York, na sede do Banco Mundial, e debatido ontem, em Barcelona, no Congresso Mundial de Conservação. Chamado “Bilhões afundados: justificativas econômicas para uma reforma na pesca”, o relatório diz que mudanças na administração da indústria pesqueira poderiam levar à recuperação das populações de peixes e aumentar os lucros.

– Há duas razões para estarmos sofrendo graves perdas.

A primeira é que os estoques pesqueiros mundiais chegaram a um nível muito mais baixo do que o tolerável.

Os barcos de pesca passam mais tempo no mar para manter a produção. Se a população de peixes se recuperasse, os custos seriam reduzidos. A segunda razão é que a falta de regulamentação adequada da pesca em vários países impede o combate da sobrepesca – disse Rolf Willman, especialista em pesca da FAO e um dos autores do estudo.

A produção mundial de pescado se mantém estável, em cerca de 80 milhões de toneladas no mar, há dez anos. Porém, os barcos são obrigados a passar cada vez mais tempo no mar. Além disso, as espécies mais valiosas estão desaparecendo e, com isso, reduzindo os lucros.

O relatório defende a redução da frota e o aumento da eficiência.

Wilman estima que as frotas pesqueiras poderiam capturar a mesma quantidade de peixes com a metade do número atual de embarcações. Para isso, segundo o estudo, é necessário um melhor mapeamento das áreas de pesca. O relatório sugere ainda que os governo incentivem a pesca sustentável. Segundo o estudo, alguns países, como Austrália e Nova Zelândia, já adotaram medidas eficientes para controle da pesca.

US$50 billion lost by marine fishing each year

New World Bank – FAO report reveals “the sunken billions”

9 October 2008, Rome/Washington – Economic losses in marine fisheries resulting from poor management, inefficiencies, and overfishing add up to a staggering US$50 billion per year, according to a new World Bank-FAO report released today. Taken over the last three decades, these losses total over $US2 trillion, a figure roughly equivalent to the GDP of Italy.

But The Sunken Billions: The Economic Justification for Fisheries Reform, a joint study by the two agencies, also argues that well-managed marine fisheries could turn most of these losses into sustainable economic benefits for millions of fishers and coastal communities.

“Sustainable fisheries require political will to replace incentives for overfishing with incentives for responsible stewardship,” said Kieran Kelleher, Fisheries Team Leader for the World Bank. “It is not just about boats and fish. This report provides decision makers with the economic arguments for the reforms needed.”

Strengthened fishing rights can provide fishers and fishing communities with incentives to fish in an economically efficient and socially responsible manner. Phasing out subsidies that enhance redundant fishing capacity and harvesting effort will improve efficiency. Greater transparency in allocation of fish resources and greater public accountability for fisheries management and health of fish stocks will help ecolabelling initiatives to certify sustainable fisheries.

According to the report the bulk of losses occur in two main ways.

First, depleted fish stocks mean that there are fewer fish to catch, and therefore the cost of finding and catching them is greater than it might be. Second, fleet overcapacity means that the economic benefits of fishing are dissipated due to redundant investment and operating costs.

The report stresses that figure of US$50 billion represents a conservative estimate – it excludes losses to recreational fisheries and marine tourism as well as losses due to illegal fishing.

Excess fishing capacity

Long before the fuel price increases of 2008, the economic health of the world’s marine fisheries was in decline.

The build-up of fishing fleets, deployment of increasingly powerful fishing technologies and increasing pollution and habitat loss has depleted fish stocks worldwide. Global marine catches have been stagnant for over a decade, hovering at around 85 million tons per year. Meanwhile fisheries productivity — measured in terms of catch per fisher, or per fishing vessel — has declined, even though fishing technology has advanced and fishing effort increased.

“There is a massive overcapacity in the global fishing fleet,” said Kelleher. “The excess fleets competing for limited fish resources result in stagnant productivity and economic inefficiency.”

If world fish stocks were rebuilt, the current marine fisheries catch could be achieved with approximately half of the current global fishing effort, the report says.

Underperformance and hidden costs

According to FAO, over 75 percent of the world’s fish stocks are either fully exploited or overexploited.

But the focus on the state of stocks has tended to obscure the even more critical economic health of the fisheries. When fish stocks are fully exploited, the associated fisheries are almost invariably performing below their economic optimum, The Sunken Billions reports. In some cases, fisheries may be biologically sustainable but still operate at an economic loss.

And while many fisheries are profitable, the global picture is that fish catching operations are buoyed up by subsidies, the report finds. “At the global level, each ton of fish caught uses almost half a ton of fuel – much of it wasted in redundant harvesting effort,” it notes.

“Right now, no one is winning,” said Rolf Willmann, a Senior Fishery Planning Officer with FAO and one of the report’s authors. “The real income levels of fishers are depressed, much of the industry is unprofitable, fish stocks are depleted and other sectors of the economy foot the bill for an ailing fishing industry.”

“Recovery of ‘the sunken billions’ can take place in two main ways,” according to the report.

First, a reduction in fishing effort would increase productivity, profitability, and net economic benefits. Second, rebuilding fish stocks would lead to increased sustainable yields and lower fishing costs.

Benefits for developing countries

Economically healthy fisheries are fundamental not only to the restoration of fish stocks but improved livelihoods, exports, fish food security and economic growth. Marine fishing operations are only part of the US$400 billion global seafood industry, but economically healthy catch operations underpin the sustainability of supply and profitability of processing and distribution activities, a major source of employment, particularly in developing countries.

“For each person employed at sea another three people are employed on shore,” noted Willmann. “Fish is the main animal protein for over 1 billion people. It provides livelihoods for over 200 million people and 90 percent of these people are in developing countries.”

Signs of progress

The good news is that governance reforms have turned the tide in some fisheries, The Sunken Billions notes.

“Strengthening fishing rights systems is fundamental to addressing the problems facing the sector,” said Ragnar Arnason, a fisheries economist at the University of Iceland and a co-author of the report, pointing to successful experiences in Iceland, New Zealand and Namibia.

Strengthening the use-, access- or ownership rights of fishers is supported by a growing number of organizations that see the need to create incentives for responsible stewardship. Promotion of ‘rights-based fisheries’ features in ASEAN’s Resolution on Sustainable Fisheries for Food Security for the ASEAN Region. In Africa the Abuja Declaration on Sustainable Fisheries and Aquaculture in Africa, adopted by the Heads of State Meeting of the NEPAD “Fish for All Summit” in Nigeria in 2005 also endorsed ‘rights-based fisheries’. The world’s largest fishery, Peru’s anchoveta fishery, is also moving towards a rights-based approach, where it is proposed to make the fishery pay for a social safety net for fishers.

“Governance reforms are often politically difficult, particularly if some reduction in fishing fleets or in the numbers of fishers may occur, says Kelleher, and the rights and livelihoods of fishers should be secured in any reform process.
