Marine Food Security

Once modern fishing fleets target a particular pelagic fish species, they can eliminate about 80% of the population in 15 years.

Methods such as bottom trawling and long lining catch many unwanted species.  About 25% of the total global catch is by-catch and discarded. (About 60 billion lbs. a year)

Below is an introduction from Green Peace on bottom trawling


Fish are being caught at 40% more than the oceans can replace.  Sustainable fishing requires rethinking subsidies, appropriate use of technology, and better management practices.  The U.N. Food and Agriculture Organizations estimates 75% of fish stocks are in jeopardy

Ocean Dead Zones are increasing from both pollution and climate change.  This in turn is reducing fisheries and increasing the problem of marine food security.

One tool for education on sustainable fisheries is a new text message program.

Marine Food Security Facts

 -In the U.S. alone fishing is a $50 billion industry annually.

 -U.N. FAO estimates 52% of fish are harvested at maximum levels and 24% over exploited.

 -50% of the world’s protein comes from fish.

 -Pollution is impacting food security

 -Climate change is expected to increase food security issues.

The Waves of Change is working with groups such as the Ocean Legacy to promote sustainable fishing.

The Waves of Change is also encouraging the development of aquaculture to take some of the pressure off of the Oceans.

Humanity is ending its Goldlilocks geological era Last Updated on 2015-01-29 15:06:36 In the space of one lifetime, human interference is bringing the conditions of the Holocene - the only ones in which we know we can flourish - to an end, writes Geoffrey Lean. It has been a Goldilocks geological era. The last 11,700 years have not been too hot, or too cold, too wet or too dry and have witnessed an earth well provided with freshwater and a great array of biomes and life. They have provided almost a planetary ceasefire after a long history of abrupt swings between very much more hostile hot and cold conditions. So it is not surprising that it has been in the Holocene (the term comes from the Greek words for "whole" and "new") that human civilisation was born, grew and spread. We entered it as a few hunter-gatherers, but have now grown so dominant that scientists believe that we are ourselves bringing the Goldilocks era to an end, with unknown –... More »
Tracking Fishy Behavior, From Space Last Updated on 2014-11-16 20:10:18                     Fishing boats in the Phoenix Islands (Christopher Pala) by Christoper Pala A new program aims to allow anybody to watch for poachers using satellite imagery and ship positioning systems. But whether it will actually send illegal fishing crews to court is an open question.Since the first hook caught the first fish perhaps 40,000 years ago, technology has raced with increasing speed to extract more and more fish from the oceans. Most big fish are long gone and fishing vessels are inexorably hauling in the rest—sometimes legally, sometimes not. But on Friday, American non-profits SkyTruth and Oceana, supported by Google, unveiled a prototype program called Global Fishing Watch that will eventually allow anyone with a computer to observe which vessel is fishing where—and perhaps infer whether...

World court harpoons Japanese whaling program Last Updated on 2014-04-01 21:08:11 The International Court of Justice in The Hague has dismissed Japan's claims that its whaling program is for scientific research and ordered the country to halt whaling activities in the Southern Ocean.                       Japanese whaling in the Antarctic will temporarily come to an end following a landmark decision by the International Court of Justice (ICJ). The court dismissed Japan's claims their fleets were hunting whales for scientific purposes, citing shortcomings in program design and poor evidence that the program produced scientific data. The world court also slammed Tokyo for failure to explain why Japanese fleets killed far more animals than seemed necessary for data collection. "We are disappointed," said Nori Shikata, spokesman for the Japanese government on this case. "Our... More »
Multiple ocean stresses threaten "globally significant" marine extinction Last Updated on 2014-01-04 14:54:36     A high-level international workshop convened by IPSO met at the University of Oxford earlier this year. It was the first inter-disciplinary international meeting of marine scientists of its kind and was designed to consider the cumulative impact of multiple stressors on the ocean, including warming, acidification, and overfishing. The 3 day workshop, co-sponsored by the International Union for Conservation of Nature (IUCN), looked at the latest science across different disciplines. The 27 participants from 18 organisations in 6 countries produced a grave assessment of current threats — and a stark conclusion about future risks to marine and human life if the current trajectory of damage continues: that the world's ocean is at high risk of entering a phase of extinction of marine species unprecedented in human history. Delegates called for urgent and... More »
Food Choices Are A Key Strategy for Sustainable Tourism Last Updated on 2013-11-25 12:44:35 Most people agree that good tasting food is part of what makes our travels more enjoyable. Unfortunately, the food served at tourism resorts is often not very sustainable. Our food choices do impact tourism in several ways including the climate change impacts, higher energy costs, soil erosion and loss of agricultural land, and marine environment pollution from fertilizers. It is estimated that global food production contributes between 14 and and 22% of total CO2 the world produces every year. Food production is one of the greatest sources of greenhouse gas emissions including: emissions from animals fertilizer use transport of food deforestation to develop cropland The U.N. Food & Agriculture Organization reports that our diets, especially meats, may cause more CO2 than industry or transportation. Higher energy costs can make tourism operations less profitable. As...
