Lots Of Renewable Energy Jobs

By Leave a Comment

According to the International Renewable Energy Agency, there were 11 million people employed in renewable energy worldwide in 2018.  This compares with 10.3 million in 2017.  So roughly three-quarters of a million new jobs were added last year.   As more and more countries manufacture, trade and install renewable energy technologies, renewables jobs continue to reach new high levels.

The geographic footprint of renewable energy jobs is changing.  Until now, renewable energy industries have remained relatively concentrated in a handful of major markets such as China, the US, and the European Union.  But more recently, East and Southeast Asian countries have emerged alongside China as key exporters of solar technology.  Malaysia, Thailand, and Vietnam were responsible for a greater share of growth in renewables last year.  Overall, Asia has a 60% share of renewable energy jobs worldwide.

Beyond climate goals, low-carbon economic growth has become a driver for renewables technology.  Renewables deliver on all the major elements of sustainable development:  environmental, economic and social.

The solar photovoltaic industry continues to be the most dynamic renewable enterprise.  It accounts for a third of the renewable energy workforce with more than three million jobs.  

Biofuel jobs were up by 6% to over 2 million.  Wind power supports 1.2 million jobs, with onshore projects predominant.  But the offshore wind segment is gaining traction.  Hydropower is still the largest installed capacity of all renewables but is now only expanding slowly.  The hydropower sector employs 2.1 million people directly, three-quarters in operations and maintenance.

A Giant Solar Farm In Dubai

By Leave a Comment

Like many places in the Middle East, Dubai made its fortune from oil.  But the Emirate’s oil resources are limited, and its economy has evolved in other directions.  Today, oil provides less than 5% of Dubai’s revenues; its economy relies on revenues from trade, tourism, aviation, real estate, and financial services.

Dubai is also away from fossil fuels to meet its energy needs. A monumental construction project is underway deep within Dubai’s desert interior which will be the largest solar energy facility in the world.

The Mohammed Bin Rashid Al Maktoum Solar Park – named after Dubai’s ruler – has been under development for 7 years.  Total investment in the project will be nearly $14 billion when it is completed in 2030.  It will have a total capacity of 5,000 megawatts, enough to power 1.3 million homes.  Only some large hydroelectric power plants, the largest nuclear power plants, and a couple of Asian coal plants have more generating capacity.

Phases one and two of the project are already complete and feature more than 2 million solar panels.  Phase three – well along the way in construction – will add another 3 million solar panels and should be completed next year.

Phase four will not involve solar panels but instead will make use of the world’s tallest concentrated solar power tower.  It will use mirrors to focus sunlight at the top of the tower to heat up molten salt that will power steam turbines to generate electricity and will be able to operate long after the sun goes down.

Currently, the Tengger Desert Solar Park in China is the largest photovoltaic park in the world, but a colossal farm in India will take its place in a few years.  Big solar is getting bigger all the time.

Frogs Are In Big Trouble

By Leave a Comment

Scientists first noticed in the 1970s that some frog populations were declining rapidly.  By the 1980s, some species appeared to be extinct.  The loss of frog species was mysterious because many were actually living in pristine habitats that did not face pollution or deforestation.

By the late 1990s, researchers had identified that frogs in widely different places around the world were infected with a deadly fungus called Batrachochytrium dendrobatidis – or Bd for short.  The fungus originated on the Korean peninsula, but the pathogen spread throughout the world, probably via the international trade in pet amphibians.  By 2007, researchers speculated that Bd might be responsible for all known declines of frogs that had no other apparent cause – about 200 species.

Recently, a group of 41 scientists published the first worldwide analysis of the fungal outbreak and the devastation turns out to be far worse than anyone had previously realized.  Populations of more than 500 species of amphibians have declined significantly because of the outbreak, including at least 90 species presumed to have gone extinct.  These figures are more than twice as large as earlier estimates.

According to biologists, Bd is now considered to be the deadliest pathogen known to science.  But the decimation of frogs peaked in the 1980s.  Today, although 39% of the species that suffered population declines in the past are still declining, 12% are showing signs of recovery, possibly because natural selection is favoring resistant animals.

There is cautious optimism for the surviving amphibian species, but scientists worry that another strain of Bd or some different species of fungus altogether may prove even deadlier.  The best we can do is not participate in moving pathogens around the world.

Shipping And Invasive Species

By Leave a Comment

The increasing numbers of invasive species around the world are a major driver of biodiversity change and cause billions of dollars in economic damages annually.  Climate change is a major factor in the spread of invasive species, but a new study by McGill University suggests that global shipping growth will far outweigh climate change in the spread of non-indigenous pests to new environments in the coming decades.

One of the most significant ways in which the disparate regions of the world are interconnected is via transportation networks.   The global shipping network is the primary means by which materials and goods are moved worldwide, accounting for over 80% of world trade.  And for this reason, the global shipping network is responsible for much of the introduction of non-indigenous species across the planet.

Living organisms are often transported through ballast water, which is taken up to stabilize cargo vessels.  Other species are transported by biofouling, whereby they attach to the hulls of ships.  Taken together, these two pathways account for anywhere between 60 and 90% of marine bioinvasions.   (Terrestrial invaders are generally moved as a byproduct of shipping, for example by infesting wood packaging material).

The McGill study looked at trends in global shipping and how socioeconomic factors are driving change.  For example, China’s share of global container throughput has gone from 1.4% in 1990 to 20.1% in 2013.  So, the distribution and patterns of shipping have been changing dramatically and with it the spread of non-indigenous species.

Awareness of this issue is increasing.  For example, there have been policy initiatives such as the International Ballast Water Management Convention that is an effort to control bio-invasions through measures such as ballast exchange.  We need to take measures to limit the unintentional spread of species.

The Price of Chocolate

By 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.

The Rosewood Trade

By Leave a Comment

Illegal trafficking in endangered flora and fauna is a topic of great interest and concern.  We hear a lot about elephant ivory, rhino horn, and even pangolin scales.  It turns out that the most trafficked form of flora or fauna in the world is actually rosewood.  According to the United Nations Office on Drugs and Crime, rosewood is traded more than ivory, rhino horn, and pangolin scales put together as measured either by volume or economic value.  According to Earthsight, a London-based nonprofit that investigates environmental crime, rosewood might account for 40% of overall illegal species trade.

Almost all rosewood is headed to China, where the beautiful wood is used in traditional hongmu furniture.   A single bed made from particularly desirable Madagascar rosewood can cost a million dollars.

The illegal rosewood trade has decimated many species of the trees around the world.  A tiny village in Madagascar has seen its population grow by 5,000 in recent years because of migrants coming to work as rosewood loggers.  The rosewood trade has been banned in Madagascar for decades, but a well-established system of bribes has effectively eliminated that problem.  Corruption at all levels allows Madagascar rosewood to find its way onto ships and off to China.

In 2017, the Convention on International Trade in Endangered Species of Wild Fauna and Flora listed all of the world’s rosewood species under its Appendix II, prohibiting all trade except in the rare cases where a local CITES authority issues sustainability permits.

As is the case for other trafficked endangered species, until the demand for the products disappears, people will find a way to make them available.  And meanwhile, these beautiful trees are rapidly disappearing.

Banning Foreign Trash

By Leave a Comment

Since the 1980s, China has been the largest importer of foreign trash.  In 2012, up to 56% of global exported plastic waste wound up in China.  The trash has been both a valuable resource for the country’s booming manufacturing sector as well as an enormous source of environmental and health problems.

More Fake Fish News

By Leave a Comment

There has been quite a bit of news in recent years about the mislabeling of fish sold in markets and restaurants.  One study a few years ago concluded that 1/3 of fish sold is not what it is labeled to be. Much of the practice is economic fraud:  substituting cheaper, easier-to-find fish for rarer, more valuable types.  For example, the study found that fish sold as red snapper was almost always not what it claimed to be.  But cheating paying customers is not the only problem associated with the misidentification of fish.

A Threat to Rhinos

Snow Leopards And Humans

By

Snow leopards are majestic animals native to Central Asia.  They roam the region’s rugged terrain, from Afghanistan to Kazakhstan and Russia in the north, and to India and China in the east.  Snow leopards are known for their thick white coat of fur with ringed black and brown spots.  These markings help camouflage the animals from their prey.  But the camouflage does little to protect snow leopards from one of their biggest threats: humans.
