Could special bonds fund the green revolution and stabilize the climate?
(02/02/2010) There is no question that governments around the world are moving slowly and sluggishly to combat climate change, especially when placed against the measures recommended by climate scientists. Only a handful of nations have actually cut overall greenhouse gas emissions, and the past couple decades have seen emissions rise rapidly worldwide as nations like India and China industrialize while Brazil and Indonesia continue massive deforestation. Global temperatures are rising in concert (though with natural fluctuations): the past decade is the warmest on record. After the failure of Copenhagen this past December to produce an ambitious and binding treaty, many are wondering if the world will ever address the threat of climate change or if future generations are set to live in a world far different—and more volatile—than the one we currently enjoy.
Why top predators matter: an in-depth look at new research
(02/02/2010) Few species have faced such vitriolic hatred from humans as the world's top predators. Considered by many as pests—often as dangerous—they have been gunned down, poisoned, speared, 'finned', and decimated across their habitats. Even where large areas of habitat are protected, the one thing that is often missing are top predators. However, new research over the past few decades is showing just how vital these predators are to ecosystems. Biologists have long known that predators control populations of prey animals, but new studies show that they may do much more. From controlling smaller predators to protecting river banks from erosion to providing nutrient hotspots, it appears that top predators are indispensible to a working ecosystem. Top predators sit at the apex of an ecosystem's food chain. Wolves in Alaska, tigers in Siberia, lions in Kenya, white sharks in the Pacific are all examples of top predators.
Will it be possible to feed nine billion people sustainably?
(01/28/2010) Sometime around 2050 researchers estimate that the global population will level-out at nine billion people, adding over two billion more people to the planet. Since, one billion of the world's population (more than one in seven) are currently going hungry—the largest number in all of history—scientists are struggling with how, not only to feed those who are hungry today, but also the additional two billion that will soon grace our planet. In a new paper in Science researchers make recommendations on how the world may one day feed nine billion people—sustainably.
Photos: park in Ecuador likely contains world’s highest biodiversity, but threatened by oil
(01/19/2010) In the midst of a seesaw political battle to save Yasuni National Park from oil developers, scientists have announced that this park in Ecuador houses more species than anywhere else in South America—and maybe the world. "Yasuní is at the center of a small zone where South America's amphibians, birds, mammals, and vascular plants all reach maximum diversity," Dr. Clinton Jenkins of the University of Maryland said in a press release. "We dubbed this area the 'quadruple richness center.'"
Congo basin rainforest countries
(01/15/2010) Payments for ecosystem services may be a key component in maintaining Central Africa's rainforests as healthy and productive ecosystems, finds a comprehensive assessment of the region's forests.
Forest carbon conservation projects top $100 million
(01/14/2010) The market for carbon credits generated through forest conservation topped $100 million from 2007 through the first half of 2009, despite a global recession and plunging carbon prices in regulated markets, reports a new assessment by Ecosystem Marketplace.
Saving biodiversity 'on the same scale' as climate change: German Chancellor
(01/11/2010) In a kick-off event for the UN's Year of Biodiversity, German Chancellor Angela Merkel, compared the importance of saving biodiversity to stopping climate change.
Bottom-dwelling sea animals play surprising role in carbon sequestration
(01/07/2010) Researchers have long known that some marine animals, such as plankton, play big roles in the carbon cycle, but a new study shows that a long-ignored family of marine animals, the bottom-dwelling echinoderms, also do their part in the carbon cycle.
Bridge development in Kalimantan threatens rainforest, mangroves, and coral reef
(01/03/2010) Balikpapan Bay in East Kalimantan is home to an incredible variety of ecosystems: in the shallow bay waters endangered dugong feed on sea grasses and salt water crocodiles sleep; along the bay proboscis monkeys leap among mangroves thirty meters tall and Irrawaddy dolphins roam; beyond the mangroves lies the Sungai Wain Protection forest; here, the Sunda clouded leopard hunts, sun bears climb into the canopy searching for fruits and nuts, and a reintroduced population of orangutans makes their nests; but this wilderness, along with all of its myriad inhabitants, is threatened by a plan to build a bridge and road connecting the towns of Penajam and Balikpapan.
Guyana to increase oversight of gold mining under deal to save forests with Norway
(12/21/2009) As apart of a deal with Norway to preserve its rainforests, Guyana will step up oversight of its gold mining industry, which has been accused of causing significant environmental damage including deforestation and mercury and cyanide pollution.
Uninhabited tropical island paradise seeks REDD funding to save it from loggers
(12/17/2009) Tetepare may be one of the last tropical island paradises left on earth. Headhunting and a mysterious illness drove its original inhabitants from the island two hundred years ago, making Tetepare today the largest uninhabited island in the tropical Pacific. The 120 square kilometer island (46 square miles), long untouched by industry or agriculture, is currently threatened by logging interests. However, the island is not without champions: in 2002 descendents of the original inhabitants of Tetepare formed the Tetepare Descendents Association (TDA) to preserve the island. Recently they have teamed up with the Solomon Islands Government and the Solomon Islands Community Conservation Partnership to develop financing through REDD.
More than half world's science academies support call to save rainforests
(12/17/2009) More than half world's science academies have signed a statement supporting a plan to save tropical forests as a means to fight climate change, reports the Global Canopy Program, an initiative that has worked closely with Prince Charles to promote rainforest conservation. The statement argues that tropical forest protection is a critical strategy for reducing greenhouse gas emissions over the next 15-20 years. It calls upon world leaders to reach a consensus on a path forward for a funding package that would support the infrastructure needed to develop an effective reducing emissions from deforestation and degradation (REDD) mechanism.
REDD may miss up to 80 percent of land use change emissions
(12/11/2009) The political definition of 'forest' used in REDD (Reduce Emissions from Deforestation and forest Degradation) threatens to undermine the program's objective to conserve ecosystems for their ability to sequester carbon, according to a new analysis by the Alternatives to Slash and Burn (ASB) Partnership for Tropical Forest Margins. In an analysis of three Indonesian provinces using REDD proposals for carbon accounting, ASB found that REDD may miss up to 80 percent of the actual emissions due to land use change. The carbon accounting problems could be fixed, according to ASB, by expanding REDD's purpose from reducing emissions linked to deforestation (considering the problematic definition of forests) to reducing emission from all land use changes that either release or capture greenhouse gases, including but not limited to forests.
Obama on global warming and forest protection
(12/10/2009) President of the United States, Barack Obama, was in Oslo, Norway this morning accepting the Nobel Peace Prize, which he won in part for promising to bring the United States to the negotiating table on climate change—something he has recently done.
REDD+ could turn deforesters into forest protectors
(12/09/2009) Payments for conservation and sustainable management of forests could turn agents of forest destruction into forest protectors, according to a comprehensive analysis of national policy options to reduce deforestation released in Copenhagen by the Center for International Forestry Research (CIFOR).
Changing drivers of deforestation provide new opportunities for conservation
(12/09/2009) Tropical deforestation claimed roughly 13 million hectares of forest per year during the first half of this decade, about the same rate of loss as the 1990s. But while the overall numbers have remained relatively constant, they mask a transition of great significance: a shift from poverty-driven to industry-driven deforestation and geographic consolidation of where deforestation occurs. These changes have important implications for efforts to protect the world's remaining tropical forests in that environmental lobby groups now have identifiable targets that may be more responsive to pressure on environmental concerns than tens of millions of impoverished rural farmers. In other words, activists have more leverage than ever to impact corporate behavior as it relates to deforestation.
REDD in Madagascar
(12/08/2009) Despite damage from ongoing illegal logging, Madagascar's remaining forests are poised to benefit from the proposed REDD mechanism, a U.N.-backed scheme that would compensate tropical developing countries for reducing emissions from deforestation and degradation, reports a new paper that analyzes efforts to use carbon finance to protect the Indian Ocean island's remaining forests. The research is published in the open-access Madagascar Conservation & Development.
Deforestation emissions should be shared between producer and consumer, argues study
(11/19/2009) Under the Kyoto Protocol the nation that produces carbon emission takes responsibility for them, but what about when the country is producing carbon-intensive goods for consumer demand beyond its borders? For example while China is now the world's highest carbon emitter, 50 percent of its growth over the last year was due to producing goods for wealthy countries like the EU and the United States which have, in a sense, outsourced their manufacturing emissions to China. A new study in Environmental Research Letters presents a possible model for making certain that both producer and consumer share responsibility for emissions in an area so far neglected by studies of this kind: deforestation and land-use change.
Oceans' ability to sequester carbon diminishing
(11/18/2009) A new study—the first of its kind—has completed an annual accounting of the oceans' intake of carbon over the past 250 years, and the news is troubling. According to the study, published in Nature, the oceans' ability to sequester carbon is struggling to keep-up with mankind's ever-growing emissions. Since 2000 researchers estimate that while every year the oceans continue to sequester more anthropogenic carbon emission, the overall proportion of carbon taken in by the oceans is declining.
Ecological benefits of REDD boosted by inclusion of private landowners, potentially harmed by plantations
(11/17/2009) Reducing Emissions from Deforestation and Degradation [REDD] programs that include landowners will conserve more habitat and ensure greater ecosystem services function than programs that focus solely on protected areas, report researchers from the Woods Hole Research Center (WHRC), the Instituto de Pesquisa Ambiental da Amazônia (IPAM), and the Universidade Federal de Minas Gerais (UFMG).
Coastal habitats may sequester 50 times more carbon than tropical forests by area
(11/16/2009) Highly endangered coastal habitats are incredibly effective in sequestering carbon and locking it away in soil, according to a new paper in a report by the IUCN. The paper attests that coastal habitats—such as mangroves, sea grasses, and salt marshes—sequester as much as 50 times the amount of carbon in their soil per hectare as tropical forest. "The key difference between these coastal habitats and forests is that mangroves, seagrasses and the plants in salt marshes are extremely efficient at burying carbon in the sediment below them where it can stay for centuries or even millennia."
Countries that invest in conservation will see higher financial returns, argues report
(11/13/2009) A new report issued by the The Economics of Ecosystems and Biodiversity (TEEB) initiative makes a strong case for valuing the planet's ecosystem services. The report calls for investments in "ecological infrastructure" to protect wildlands and the services they provide; market-based valuation of ecosystem services; reductions in environmentally harmful subsidies; recognition of the link between environmental degradation and poverty; and a strong climate deal that includes forest carbon.
New report: boreal forests contain more carbon than tropical forest per hectare
(11/12/2009) A new report states that boreal forests store nearly twice as much carbon as tropical forests per hectare: a fact which researchers say should make the conservation of boreal forests as important as tropical in climate change negotiations. The report from the Canadian Boreal Initiative and the Boreal Songbird Initiative, entitled "The Carbon the World Forgot", estimates that the boreal forest—which survives in massive swathes across Alaska, Canada, Northern Europe, and Russia—stores 22 percent of all carbon on the earth's land surface. According to the study the boreal contains 703 gigatons of carbon, while the world's tropical forests contain 375 gigatons.
Declaration calls for more wilderness protected areas to combat global warming
(11/11/2009) Meeting this week in Merida, Mexico, the 9th World Wilderness Congress (WILD9) has released a declaration that calls for increasing wilderness protections in an effort to mitigate climate change. The declaration, which is signed by a number of influential organizations, argues that wilderness areas—both terrestrial and marine—act as carbon sinks, while preserving biodiversity and vital ecosystem services.
Hunting across Southeast Asia weakens forests' survival, An interview with Richard Corlett
(11/08/2009) A large flying fox eats a fruit ingesting its seeds. Flying over the tropical forests it eventually deposits the seeds at the base of another tree far from the first. One of these seeds takes root, sprouts, and in thirty years time a new tree waits for another flying fox to spread its speed. In the Southeast Asian tropics an astounding 80 percent of seeds are spread not by wind, but by animals: birds, bats, rodents, even elephants. But in a region where animals of all shapes and sizes are being wiped out by uncontrolled hunting and poaching—what will the forests of the future look like? This is the question that has long occupied Richard Corlett, professor of biological science at the National University of Singapore.
Governments, public failing to save world's species
(11/04/2009) According to the International Union for the Conservation of Nature's (IUCN) 2008 report, released yesterday, 36 percent of the total species evaluated by the organization are threatened with extinction. If one adds the species classified as Near Threatened, the percentage jumps to 44 percent—nearly half.
REDD in Colombia: using forests to finance conservation and communities in Colombia's Choco, a former war zone
(11/03/2009) Reducing Emissions from Deforestation and Degradation (REDD), a climate change mechanism proposed by the U.N., has been widely lauded for its potential to simultaneously deliver a variety of benefits at multiple scales. But serious questions remain, especially in regard to local communities. Will they benefit from REDD? While much lip-service is paid to community involvement in REDD projects, many developers approach local communities as an afterthought. Priorities lie in measuring the carbon sequestered in a forest area, lining up financing, and making marketing arrangements, rather than working out what local people — the ones who are often cutting down trees — actually need in order to keep forests standing. This sets the stage for conflict, which reduces the likelihood that a project will successfully reduce deforestation for the 15-30 year life of a forest carbon project. Brodie Ferguson, a Stanford University-trained anthropologist whose work has focused on forced displacement of rural communities in conflict regions in Colombia, understands this well. Ferguson is working to establish a REDD project in an unlikely place: Colombia's Chocó, a region of diverse coastal ecosystems with some of the highest levels of endemism in the world that until just a few years ago was the domain of anti-government guerrillas and right-wing death squads.
Gucci drops APP in pledge to save rainforests
(11/03/2009) One of the world's largest and most prestigious fashion brands has stated it will stop sourcing paper from Indonesian forests and will drop Asia Pulp and Paper (APP) as a supplier, which has become notorious for tropical deforestation. The move comes after pressure from the Rainforest Action Network (RAN) on the fashion industry to stop sourcing paper from threatened rainforests for their shopping bags.
Will Ecuador's plan to raise money for not drilling oil in the Amazon succeed?
(10/27/2009) Ecuador's Yasuni National Park is full of wealth: it is one of the richest places on earth in terms of biodiversity; it is home to the indigenous Waorani people, as well as several uncontacted tribes; and the park's forest and soil provides a massive carbon sink. However, Yasuni National Park also sits on wealth of a different kind: one billion barrels of oil remain locked under the pristine rainforest.
"Money is not a problem," palm oil CEO tells conservationists during speech defending the industry
(10/26/2009) Earlier this month at a colloquium to implement wildlife corridors for orangutans in the Malaysian state of Sabah, Dr. Yusof Basiron, the CEO of Malaysian Palm Oil Council (MPOC), told conservationists and primate experts that the palm oil industry was ready to fund reforestation efforts in the corridors. "We can raise the money to replant [the corridors] and keep contributing as a subsidy in the replanting process of this corridor for connecting forests," Basiron said in response to a question on how the palm oil industry will contribute. "Money is not a problem. The commitment is already there, the pressure is already very strong for this to be done, so it's just trying to get the thing into motion."
New reserve created in Cambodia with REDD in mind
(10/26/2009) Cambodia's Royal Government's Council of Ministers has declared the creation of the Seima Protection Forest, a 1,100 square miles (2,849 square kilometers) park home to tigers, elephants, and endangered primates. The park's creation was developed in part by the Wildlife Conservation Society's (WCS) "Carbon for Conservation" program, which intends to protect high-biodiversity ecosystems while raising funds through carbon sequestration schemes such as Reducing Emission from Deforestation and Degradation (REDD).
Freshwater species worse off than land or marine
(10/15/2009) Scientists have announced that freshwater species are likely the most threatened on earth. Extinction rates for freshwater inhabitants are currently four to six times the rates for terrestrial and marine species. Yet, these figures have not lead to action on the ground.
Could agroforestry solve the biodiversity crisis and address poverty?, an interview with Shonil Bhagwat
(09/24/2009) With the world facing a variety of crises: climate change, food shortages, extreme poverty, and biodiversity loss, researchers are looking at ways to address more than one issue at once by revolutionizing sectors of society. One of the ideas is a transformation of agricultural practices from intensive chemical-dependent crops to mixing agriculture and forest, while relying on organic methods. The latter is known as agroforestry or land sharing—balancing the crop yields with biodiversity. Shonil Bhagwat, Director of MSc in Biodiversity, Conservation and Management at the School of Geography and the Environment, Oxford, believes this philosophy could help the world tackle some of its biggest problems.
Prince Charles making progress in effort to save rainforests, says leading British environmentalist
(09/22/2009) Prince Charles of Great Britain has emerged as one of the world’s highest-profile promoters of a scheme that could finally put an end to destruction of tropical rainforests. The Prince’s Rainforest Project, launched in 2007, is promoting awareness of the role deforestation plays in climate change—it accounts for nearly a fifth of greenhouse gas emissions. The project also publicizes the multitude of benefits tropical forests provide, including maintenance of rainfall, biodiversity, and sustainable livelihoods for millions of people. But the initiative goes beyond merely raising awareness. Prince Charles is using his considerable influence to bring political and business leaders together to devise and support a plan to provide emergency funding to save rainforests. Tony Juniper, one of Britain’s best-known environmentalists and Special Adviser to the project, spoke about Prince Charles' efforts in an interview with mongabay.com.
Alleviating poverty and saving biodiversity are inherently linked argue scientists
(09/17/2009) Twenty-nine scientists argue in Science today that the world will not be able to lift up the world's poor unless it also addresses global biodiversity loss. They say that the same underlying problems—exploitation of resources, unsustainable overconsumption, climate change, population growth—are exacerbating global poverty and the extinction of species.
Innovative reforestation project threatened by 'regime change' in Madagascar, an interview with Rainer Dolch
(09/16/2009) In Madagascar the TAMS Program (Tetik'asa Mampody Savoka, meaning "the project to bring back the forest") is under threat due to the new government's unwillingness to provide funding. The current government, after gaining power in a coup this year, has frozen all funds slated for the project and has yet to sign a carbon credit agreement with the World Bank which would bring much needed funding. "It remains to be seen if the recognition or not of Madagascar's transitional Government will lead to signing the contract with the World Bank in the near future. This is of course essential for the continuity of the project and its future," Rainer Dolch told Monagaby.com in an interview.
500 scientists call on Quebec to keep its promise to conserve half of its boreal forest
(09/13/2009) This March, the Canadian province of Quebec pledged to conserve 50 percent of its boreal forest lying north of the 49th parallel, protecting the region from industrial, mining, and energy development. On Thursday 500 scientists and conservation professionals—65 percent of whom have PhDs—sent a letter to Quebec's Premier Jean Charest calling on him to make good on his promise.
Concerns over deforestation may drive new approach to cattle ranching in the Amazon
(09/08/2009) While you're browsing the mall for running shoes, the Amazon rainforest is probably the farthest thing from your mind. Perhaps it shouldn't be. The globalization of commodity supply chains has created links between consumer products and distant ecosystems like the Amazon. Shoes sold in downtown Manhattan may have been assembled in Vietnam using leather supplied from a Brazilian processor that subcontracted to a rancher in the Amazon. But while demand for these products is currently driving environmental degradation, this connection may also hold the key to slowing the destruction of Earth's largest rainforest.
Discovering nature's wonder in order to save it, an interview with Jaboury Ghazoul
(09/08/2009) Sometimes we lose sight of the forest by staring at the trees. When this happens we need something jarring and eloquent to pull us back to view the big picture again. This is what tropical ecologist Jaboury Ghazoul provided during a talk at the Association of Tropical Biology and Conservation (ATBC) meeting this summer in Marburg, Germany. Throwing out a dazzling array of big ideas and even bigger questions—incorporating natural history, biodiversity, morality, philosophy, and art—the enthusiastic Ghazoul left his audience in a state of wonder.
Investing in conservation could save global economy trillions of dollars annually
(09/03/2009) By investing billions in conserving natural areas now, governments could save trillions every year in ecosystem services, such as natural carbon sinks to fight climate change, according to a European report The Economics of Ecosystems and Biodiversity (TEEB).
Trees sprout across farmland worldwide
(08/26/2009) Half the planet's farmed landscapes have significant tree cover, reports a new satellite-based study. The research, conducted by the Consultative Group on International Agricultural Research's World Agroforestry Centre found that tree cover exceeds 10 percent on more than 1 billion hectares of farmland, indicating that agroforestry is a "vital part" of worldwide agricultural production. 320 million hectares of forested agricultural land are found in Latin America, 190 million hectares in sub-Saharan Africa and 130 million hectares in Southeast Asia.
Ecological restoration substantially boosts biodiversity and ecosystem services
(07/30/2009) A new analysis reports that ecological restoration generally deliver benefits for both conserving biodiversity and supporting human livelihoods, but does not completely reverse degradation caused by humans.
Are we on the brink of saving rainforests?
(07/22/2009) Until now saving rainforests seemed like an impossible mission. But the world is now warming to the idea that a proposed solution to help address climate change could offer a new way to unlock the value of forest without cutting it down.Deep in the Brazilian Amazon, members of the Surui tribe are developing a scheme that will reward them for protecting their rainforest home from encroachment by ranchers and illegal loggers. The project, initiated by the Surui themselves, will bring jobs as park guards and deliver health clinics, computers, and schools that will help youths retain traditional knowledge and cultural ties to the forest. Surprisingly, the states of California, Wisconsin and Illinois may finance the endeavor as part of their climate change mitigation programs.
Temperate forests store more carbon than tropical forests, finds study
(07/17/2009) Temperate forests trump rainforests when it comes to storing carbon, reports a new assessment of global forest carbon stocks published July 14th in Proceedings of the National Academy of Sciences (PNAS). The findings have important implications for efforts to mitigate climate change by protecting forests. Sampling and reviewing published data from nearly 100 forest sites around the world, Heather Keith, Brendan G. Mackey, and David B. Lindenmayer of Australian National University found that Australia's temperate Eucalyptus forests are champions of carbon storage, sequestering up to 2,844 metric tons of carbon per hectare, a figure that far exceeds previous estimates. These forests, located in the Central Highlands of Victoria in southeastern Australia, are dominated by giant Mountain Ash (Eucalyptus regnans) trees, which can reach a height of 320 feet and live for more than 350 years. They are also favored by the timber industry. Mountain Ash forests have been widely logged across Australia, with only limited old-growth stands remaining.
A Tasmanian tragedy? : How the forestry industry has torn an island apart
(07/02/2009) This is by no means a new battle: in fact, Tasmanian industrial foresters and environmentalists have been fighting over the issue of clearcutting the island’s forests for decades. The battle—some would probably prefer 'war'—is over nothing less than the future of Tasmania. Some Tasmanians see the rich forests that surround them in terms of income, dollars and cents; they see money literally growing on trees, or more appropriately growing on monoculture plantations and government owned native forests. They see the wilderness of Tasmania as an exploitative resource.
Coastal seagrass disappearing as quickly as coral reefs and rainforests
(06/30/2009) Findings from the first comprehensive global survey of coastal seagrass ecosystems are nothing to cheer about. Fifty-eight percent of seagrass meadows are declining, according to an international team of scientists who compiled data from 215 studies and 1,800 observations of seagrass habitat beginning in 1879. Since that year, 29 percent of seagrass ecosystems have vanished entirely.
Massive deforestation in the past decreased rainfall in Asia
(06/25/2009) Between 1700 and 1850 forest cover in India and China plummeted, falling from 40-50 percent of land area to 5-10 percent. Forests were cut for agricultural use across Southeast Asia to feed a growing population, but the changes from forests to crops had unforeseen consequences. A new study published in the Proceedings of the National Academy of Sciences links this deforestation across Southeast Asia with changes in the Asian Monsoon, including significantly decreased rainfall.
Brazil's plan to save the Amazon rainforest
(06/02/2009) Accounting for roughly half of tropical deforestation between 2000 and 2005, Brazil is the most important supply-side player when it comes to developing a climate framework that includes reducing emissions from deforestation and forest degradation (REDD). But Brazil's position on REDD contrasts with proposals put forth by other tropical forest countries, including the Coalition for Rainforest Nations, a negotiating block of 15 countries. Instead of advocating a market-based approach to REDD, where credits generated from forest conservation would be traded between countries, Brazil is calling for a giant fund financed with donations from industrialized nations. Contributors would not be eligible for carbon credits that could be used to meet emission reduction obligations under a binding climate treaty.
Polluted, degraded ecosystems can recover in less than a lifetime
(05/31/2009) Restoration efforts can return polluted or degraded landscapes to previous states in less than a lifetime, according to study Yale School of Forestry and Environmental Studies. The study rebuts a common assumption that ecosystem recovery takes centuries, even millennia.
Revolutionary new theory overturns modern meteorology with claim that forests move rain
(04/01/2009) Two Russian scientists, Victor Gorshkov and Anastassia Makarieva of the St. Petersburg Nuclear Physics, have published a revolutionary theory that turns modern meteorology on its head, positing that forests—and their capacity for condensation—are actually the main driver of winds rather than temperature. While this model has widespread implications for numerous sciences, none of them are larger than the importance of conserving forests, which are shown to be crucial to 'pumping' precipitation from one place to another. The theory explains, among other mysteries, why deforestation around coastal regions tends to lead to drying in the interior.
