The worldwide fishing industry could benefit from a $50 billion boost
annually if stocks were allowed time to recover, the UN said Wednesday.
Already 32 percent of the world's fish stocks
have been depleted by years of overfishing and poor coastal management,
according to a UN Environment Programme report released in Pasig City.
"The
potential economic gain from reducing fishing capacity to an optimal
and restoring fish stocks is in the order of $50 billion per annum," a
summary of the UN report said.
The report said
overfishing, pollution from land-based farming and industry, and the
destruction of habitat, including coral reefs and mangroves, were all
having an effect on fish stocks.
This was directly
affecting the 540 million people around the world who are dependent on
the fishing industry, experts at the launch of the "Green Economy in a
Blue World" report said.
Cutting pollution would help
fish stocks and fishermen's catches to rebound, Amina Mohammed, deputy
executive director of the UNEP, said.
"Many ocean
industries and businesses stand to benefit directly from cleaner, more
ecologically robust marine ecosystems," she said.
While overfishing reduces fish stocks, pollution from the overuse of fertilizer in farming is also a major problem, she said.
The
fertilizer washes into the sea, resulting in runaway growth of algae
which sucks up all the oxygen in the waters and causes fish to "drown".
Experts have said there are over 500 oxygen-deprived "dead zones" in waters around the world created in such a way.
Europe
could save at least $100 million annually just through improvements in
fertilizer use to stop it affecting the oceans, said Linwood Pendleton,
an oceans and coast expert from the United States' Duke University.
Marine
specialist Raphael Lotilla said that as much as 49 percent of all
fertilizer used in Philippine farms ended up being washed into the sea.
"Let's work with farmers to figure out what is the right amount of fertilizer so everyone wins," Mohammed said.
The UN report also said marine-based renewable energy sources like wind, wave and tidal power, have huge potential but are not yet cost competitive.
It
called for "long-term policies and targeted financial support from
governments" such as grants, subsidies and tax credits, to improve the
technology and bring costs down.
It also called for
more measures to curb destruction of coral reefs, mangroves, seagrass
beds and other marine habitats, as well as measures to prevent the
spread of "invasive species" carried by ships' hulls.
Such species cause an estimated $100 billion in losses each year, the report said.
United Nations Report: Green Economy in a Blue World
Water Spouts will speak volubly and endlessly about all the issues concerning water. The ongoing degradation, and growing scarcity, of the water supply here in the US, and the rest of the world. The continued absence of potable water in so many parts of the world. The work being done by NGOs, and charities, in the third world, to help alleviate the situation. The emphasis on WASH ( Water, Sanitation, and Hygiene ) so health and healthy water are maintained. "Water Spouts" will spout it all out.
