The Price of Chocolate

April 18, 2019 By EarthWise Leave a Comment

The Ivory Coast has lost more than 80% of its forests in the last 50 years, mainly as a result of cocoa production.

The Ivory Coast is a West African country the size of New Mexico and it produces more than a third of the world’s cocoa.  But around 40% of the country’s cocoa crop – supplying more than a tenth of the world’s chocolate bars – is grown illegally in the country’s national parks and 230 supposedly protected government-owned forests. 

Over the decades, as many as one million landless people from drought-stricken places like Mali and Burkina Faso moved into national parks and protected forests and started farming cocoa.  The Marahoue National Park alone has 30,000 illegal inhabitants.

Most cocoa is grown in monocultures of what is known as the full-sun system, which requires the removal of all surrounding trees.  As a result, many allegedly protected areas have been completely converted into farms.  Most of the cocoa in the Ivory Coast is grown on small farms, typically plots of 7 to 10 acres.  The farmers are caught in an exploitative and corrupt system of cocoa trading and land appropriation, and most earn less than a dollar a day.  Meanwhile, government agencies charged with protecting the forests are more interested in collecting bribes than safeguarding woodlands.

The Ivory Coast government is unveiling a plan to actually remove protection from most of its remaining forests and hand them over to the world’s chocolate traders.    The claim is that this will protect other forests by improving cocoa productivity in already deforested areas.  Needless to say, conservation groups are dubious that the new plan will positively impact an already terrible situation.

California Fires And Precipitation

April 11, 2019 By EarthWise Leave a Comment

Two things we have heard a lot about in recent years have been the persistent drought in California and the terrible wildfires the state has experienced.  Along the way, the state has had some pretty wet and snowy winters.  This past winter, the California snow pack has seen incredible levels building up, which is great news for the state’s farmers.  But does that also mean that the next year should see some relief from severe wildfires?

The answer appears to be no.  A new study from an international team that includes the University of Arizona has comprehensively looked at the amount of winter precipitation in California and the severity of the subsequent wildfire season. 

The position of the North Pacific jetstream over California is strongly linked to the amount of winter precipitation.  This has been true for hundreds of years and continues to be the case.

From 1600 to 1903, the linkage between winter precipitation and wildfire severity was also very strong.  But after 1904, that connection weakened.  As a result, fire suppression policies were instituted.  When fires arose, they were put out as quickly as possible.  The result over time is fuel buildup, making larger fires far more likely.

According to the new study, after 1977, the connection between winter precipitation and wildfire severity disappeared entirely.  There no longer appears to be any relationship between jet stream dynamics and fire.  The warming climate and the results of fire suppression dominate the potential for wildfire.  California’s wet winter of 2016-2017 provides a good example.  That winter was followed by many large fires in 2017.

So, this very wet winter in California does not imply that this should be a year without severe wildfires.

Indonesian Deforestation

February 28, 2019 By EarthWise Leave a Comment

Deforestation is defined as the intentional destruction of trees and other vegetation without reforesting or allowing the forest to regenerate itself. 

In Indonesia, industrial agriculture, primarily for the production of palm oil, is a major driver of deforestation.  But, according to researchers at Duke University, its impact has diminished  proportionately in recent years as other natural and human causes have emerged. Their peer-reviewed findings were recently published in the journal Environmental Research Letters.

According to the study’s lead author, large-scale plantations were responsible for more than half of Indonesia’s deforestation in the late 2000s, peaking between 2008-2010 when an average of 1.5 million acres of forest was lost annually.  The expansion of the massive plantations was responsible for 57% of the forest loss. Between 2014-2016, an average of more than 2 million acres of forest was lost annually, but plantation expansion only accounted for 25% of this figure.  While the overall rate of deforestation continued to grow, other factors were responsible for most of it.

Conversions of forests to grasslands rose sharply in 2015 and 2016 when El Nino caused severe droughts and forest fires. Small-scale farming, often overshadowed by industrial agriculture, was also found to play a bigger role, accounting for 25% of all forest loss. 

Indonesia has experienced some of the highest rates of deforestation.  Its forests absorb and store vast amounts of climate-warming carbon dioxide, help prevent erosion and flooding, and provide habitat to thousands of species.  Understanding the varied causes of Indonesian deforestation should help conservationists and policymakers better address the problem.

Bring The Wild Back Into Farmlands

A recent study published in Science looks at the effects of maintaining at least a little bit of the wild on working lands including farmland, rangeland and forests.  The study concludes that doing so may be a key to preserving biodiversity in the face of climate change.

The Telangana region of India has struggled with extreme weather patterns attributed to climate change.  Extended periods of drought, heatwaves, and unpredictable heavy rainfalls have led to crop failures, mounting debt, and a heavy human toll.  More than 3,000 farmers committed suicide in Telangana during a three-year drought.

In the past, coral conservationists focused their efforts on protecting reefs from direct environmental threats such as land-based pollution and damaging fishing practices.   These efforts continue, but as coral reefs face increasingly dire threats, conservationists are turning toward more proactive approaches.

Rising temperatures, drought, pests and diseases are moving north into the U.S. heartland and are increasingly posing a threat to the wheat crop.  An insect called the Hessian fly is reducing crop yields by 10% a year in the Midwest.  Average temperatures in the Midwest have risen by 2 degrees since 2000, and periods of time between rainfalls is lengthening.  Conditions in some areas of the Midwest are getting to be more like those in the Middle East.

Farming In Solar Farms

Utility-scale solar installations have been expanding rapidly.  The amount of land used for solar projects is becoming quite substantial.  The National Renewable Energy Laboratory (NREL) predicts that 3 million acres will be devoted to solar farms by 2030, and 6 million by 2050.  These numbers pale in comparison with the land used for corn, soybeans, and wheat, but are more than used for such familiar crops as oats, barley and rice.

There is much to be said in favor of organic food.  The organic produce industry took in $65 billion in 2016 and that farming method is clearly increasingly popular and is here to stay.   Nevertheless, there are various misconceptions and inaccuracies related to organic food.

In November, Syria joined the Paris Climate Accord.  As a result, the United States is now the only country in the world that has rejected the global pact.  Despite this embarrassing news, there is reason for optimism in the effort to stave off the worst impacts of climate change.  In particular, 7 major trends provide hope that things could move in the right direction.

New Rules For Ocean Conservation

In a recent report to a United Nations ocean conference, scientists are warning that new rules are desperately needed to protect marine life in the open seas.  That’s because more than 60% of the ocean has no conservation rules since it’s located outside national jurisdictions.  The open ocean is at risk from climate change, over-fishing, deep sea mining, farm pollution, and plastics pollution.

Perdue Farms, the fourth-largest poultry producer in the United States, produces over 60 million pounds of chicken a week.  They are arguably the most progressive of the giant poultry companies.  Two years ago, they were the first to renounce routine antibiotic use.   In late June, they announced a comprehensive animal-welfare plan – the first among large producers – that will change how its chickens are bred, raised and killed.
