The REDD program has channeled over $117 million in direct financial aid and educational support into national deforestation reduction efforts in 44 developing countries across Africa, Asia and Latin America since its 2008 inception. Spillovers of infectious diseases to people is more likely to occur in the tropics because overall wildlife and pathogen diversity is higher, he adds. Saving the rainforests will save Florida Sun Sentinel In the case of the Amazon rainforest, research shows that at least 80% of its trees would be needed in order to keep the hydrological cycle going. WebFlorida, United States Deforestation Rates & Statistics | GFW United States Florida Select a region In 2010, Florida had 5.94Mha of natural forest, extending over 49% of its land Through careful surveys in the Peruvian Amazon, she found higher numbers of larvae in warm, partially shaded pools, the kind that form beside roads cut into forests and puddles behind debris where water is no longer taken up by trees. These diseases infect not only birds and vertebrates found in these ecosystems, but also any humans that are exposed to these insects, either in the wild or in nearby urban areas. Separate red tide algal outbreaks in the ocean ravaged Florida last year, leading to beaches being closed, horrified dog owners who saw their pets poisoned, and hundreds of tons of dead fish and manatees piling up along the Gulf coast. We have the capability to stem the tide by increasing the flow of fresh water. On a governmental level, the consequences of deforestation can be mitigated by introducing policies that protect natural forests and regulate mining and logging operations as well as other operations that require the destruction of tree plantations. At first pass, there seems little amiss in the idyll of Florida Bay. Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. , something that can have huge implications for slowing the pace of climate change and contributing to a steep rise in global temperatures. Healthy forests act as extremely valuable carbon sinks, with the Amazon rainforest being one of the worlds most important ones. The numbers are grim, but many conservationists see reasons for hope. WebDeforestation affects the world in a negative way, with the most dramatic impact being the loss of habitat for millions of species. Let us know if you have suggestions to improve this article (requires login). Starved of fresh water from a reworking of its natural plumbing further north and menaced by seas rising due to climate change, the Everglades and its adjoining bay are teetering at the edge of existential crisis. To make that case, their team has been working in Malaysian Borneo to itemize the exact cost of malaria, down to each hospital bed, and syringe that doctors use. Knowledge awaits. However, the rapid destruction of forests is contributing to a decline in biodiversity never seen before. The South American rainforest, for example, influences regional and perhaps even global water cycles, and it's key to the water supply in Brazilian cities and neighboring countries. As more and more soil is lost, the remaining soil is poorly suited to retaining moisture, leading to desertification. They range from rainforests that are hot and wet year-round to forests that are merely humid and moist, to those in which trees in varying proportions lose their leaves in the dry season, and to dry open woodlands. Most present-day croplands receive enough rain and are warm enough to have once supported forests of one kind or another. For instance, in Liberia forest clearings for palm oil plantations attract hordes of typically forest-dwelling mice, lured there by the abundance of palm fruit around plantations and settlements. In heavily deforested areas, soil erosion and nutrient runoff are common after a rainfall. How did this mountain lion reach an uninhabited island? Deforestation weakens this process, leading to irregular rainfall patterns including drought and flooding. Deforestation alters not only nearby ecosystems -- communities of interacting organisms and their environments -- but also the atmosphere on a global level, with devastating results. deforestation, the clearing or thinning of forests by humans. Florida, United States Deforestation Rates & Statistics | GFW In humans, the virus causes hemorrhagic feverthe same kind of illness triggered by Ebola virusand in Liberia killed 36 percent of infected people. The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people. MacDonald sees value in this idea: If we can conserve the environment, then perhaps we can also protect health, he says. We'll be adding other personal features soon. Explore Typically, the land produces for only a few years and then must be abandoned and new patches of forest burned. About 17 percent of the Amazonian rainforest has been destroyed over the past 50 years, and losses recently have been on the rise. Forests can also help reduce the impacts of flood from storms by blocking and slowing down the flow of runoff. A mans world? , Loss of Topsoil. Some of the carbon dioxide released into the atmosphere comes from dead vegetation that decomposes in the ground. For more information about the potential effects of habitat loss in Florida, visit the Florida Fish and Wildlife Conservation Commission Wildlife 2060 website. Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Since 1990, the world has lost more than 420 million hectares or about a billion acres of forest, according to the Food and Agriculture Organization of the United Nationsmainly in Africa and South America. According to the World Carfree Network (WCN), cars and trucks account for about 14 percent of global carbon emissions, while most analysts attribute upwards of 15 percent to deforestation. , mostly of Indian descent, divided into more than 400 indigenous tribes. EarthTalk is written and edited by Roddy Scheer and Doug Moss and is a registered trademark of E - The Environmental Magazine (www.emagazine.com). Some is caused by a combination of human and natural factors like wildfires and overgrazing, which may prevent the growth of young trees. What are the reasons behind deforestation? Where humans once used sticks and stones, they have since developed technology that dramatically accelerated the speed of erosion, Wilkinson said. But we shouldnt be sitting on our hands, Price said. When forests are cleared to make space for large plantations growing one type of crop such as sugarcane or soy, wildlife diversity tends to plummet as species are displaced. In some cases, soil erosion is natural, but humans also contribute to the problem by stripping away natural protections like trees and other vegetation, or overgrazing land with livestock.5 Ways of Preventing Soil Erosion (for Homeowners). Additional human activities that contribute to tropical deforestation include commercial logging and land clearing for cattle ranches and plantations of rubber trees, oil palm, and other economically valuable trees. DeSantis has called for the resignations of the entire South Florida Water Management District board, which controls water policy for the region, and has appointed two members Ron Alligator Ron Bergeron and Chauncey Goss who both have strong green credentials. Healthy forests act as extremely valuable carbon sinks, with the Amazon rainforest being one of the worlds most important ones. Proceedings of the National Academy of Sciences. This area, just last year smelled like death. By most accounts, deforestation in tropical rainforests adds more carbon dioxide to the atmosphere than the sum total of cars and trucks on the worlds roads. Only about 1 million square km (390,000 square miles) of cropland are in areas that would have been cool boreal forests, as in Scandinavia and northern Canada. In the practice of clear-cutting, all the trees are removed from the land, which completely destroys the forest. What is deforestation and its causes and effects? Please be respectful of copyright. In Africa, studies have found little association between malaria and deforestationperhaps because the mosquito species there like to breed in sunlit bodies of water and favor open farmland over shady forest areas. 59% occurs in Latin America, with a further 28% from Southeast Asia. Photograph by Paul Nicklen, Nat Geo Image Collection. In Malaysia and Indonesia, forests are cut down to make way for producing palm oil, which can be found in everything from shampoo to saltine crackers. This effect was most pronounced in the interior of the forest, where some patches of forest are still intact, providing the moist edge habitat that the mosquitoes like. The roughly 5,000-year-old human remains were found in graves from the Yamnaya culture, and the discovery may partially explain their rapid expansion throughout Europe. Statistics show that deforestation in the tropics, reduces precipitation over the Amazon by around 10%, , or 138 millimeter, every year. Indeed, a forthcoming study shows that left unchecked, deforestation will cost Florida timber and agriculture between $4 billion and $6 billion. Florida has even thrown itself into a legal battle to halt a controversial oil drilling project in the north-eastern reaches of the Everglades. What are the 3 major causes of soil erosion? Cattle or sheep pastures in North America or Europe are easy to identify, and they support large numbers of animals. Forests are also cut as a result of growing urban sprawl as land is developed for homes. This research is the first to show how we can predict and avoid spillovers through monitoring and maintaining wildlife habitats. Large scale tree cutting can lead to deforestation, a transformation of an area from forest to terrain with little vegetation. Discover world-changing science. Just four commoditiesbeef, soy, palm oil, and wood productsdrive the majority of global deforestation. When does spring start? Free Trial Issue: www.emagazine.com/trial. Environmental News, Data Analysis, Research & Policy Solutions. We promise, no spam! In the Amazon, cattle ranching and farmsparticularly soy plantationsare key culprits. What is wind chill, and how does it affect your body? Scott has a biochemistry degree from UCSB with research experience and has a passion for science as well as writing. Deforestation Effects on Ecosystems | Sciencing Environmentalists are optimistic that the initial success of REDD in Brazil bodes well for reducing deforestation in other parts of the tropics as well. The Amazon Rainforest is the largest remaining block of humid tropical forest, and about two-thirds of it is in Brazil. Clearing patches of forest appears to create ideal habitat along forest edges for the mosquito Anopheles darlingithe most important transmitter of malaria in the Amazonto breed. WebDeforestation not only contributes to changes in the climate, it also causes localized changes in the weather. The plan would tackle local water pollution, protect springs and finish raising the Tamiami Trail, a highway that links Miami and Floridas west coast by cutting across the Everglades, to allow water to flow south to the ecosystem. Because boundaries between these categories are inevitably arbitrary, estimates differ regarding how much deforestation has occurred in the tropics. By the 1960s, scientists had calculated that while around 2m acre feet (2.5bn cubic metres) of water once flowed in a shallow river of grass from central Florida to the states southern tip, the volume of this conveyor belt had been cut in half. Conversion of forests to land used for other purposes has a long history. Many viruses exist harmlessly with their host animals in forests, because the animals have co-evolved with them. Price said this accelerating climate trend, driven by the melting of glaciers and expanding sea water, will see the Everglades retreat further north. Human population and development activities affect the rate of deforestation in biodiversity hotspots. The tourism industry, worth about $67bn annually to Florida, trembled. All rights reserved. According to the World Wildlife Fund (WWF), as much as half of the worlds topsoil has been lost as a consequence of the nearly 4 million square miles of forest that have been lost since the beginning of the 20th century. Trees are known for their capacity to absorb carbon dioxide through photosynthesis. Explore our digital archive back to 1845, including articles by more than 150 Nobel Prize winners. Deforestation Find out how a tribe in the Amazon is using old cell phones and machine learning to help save their forest home. As their houses are destroyed and resources compromised, these tribes are forced to migrate elsewhere and find other ways to sustain themselves. A severe slump in rainfall in 2015 meant salinity levels rocketed in the bay, with the water becoming twice as salty in the ocean. However, more than 75% of the Earths surface has been modified and degraded by human activities such as deforestation. Can we bring a species back from the brink? By most accounts, deforestation in tropical rainforests adds more carbon dioxide to the atmosphere than the sum total of cars and trucks on the worlds roads. Habitat destruction is the issue most often cited for the problems now facing Florida wildlife. Why wetlands are so critical for life on Earth, Rest in compost? The FAO estimates that there are approximately 1.3 million square km (500,000 square miles) of such plantations on Earth. Increased Greenhouse Gases. Whether you need help solving quadratic equations, inspiration for the upcoming science fair or the latest update on a major storm, Sciencing is here to help. The patient is on life support at the moment, said Steve Davis, senior ecologist at conservation not-for-profit Everglades Foundation, describing what was once a prime fishing area in the western portion of the bay. In the South Asian Monsoon region, the reduction in rainfall is even higher, with around 18% less rain recorded in India in a single year. United States Deforestation Rates & Statistics | GFW - Global However, if crops are introduced on a smaller scale and don't displace native species, they can actually increase diversity since they can act as a habitat for birds and herbivores. Climate change has accelerated the rate of ice loss across the continent.
Not long after the bats settled on trees in Malaysian orchards, pigs around them started to fall sickpresumably after eating fallen fruit the bats had nibbled onas did local pig farmers. Climate change has already affected migration patterns, and infected birds may move to deforested areas that are more suitable habitats for them, spreading their diseases to the local bird populations. Some viruses, like Ebola or Nipah, can be transmitted directly between people, theoretically allowing them to travel around the world as long as there are humans. At least 2 million square km (772,204 square miles) of such forests have been cleared for grazing lands. Biodiversity is the number of species in a given ecosystem. For example, starting in 2017, the government of New Zealand sought to plant more than 100 million trees per year within its borders, but perhaps the most ambitious replanting project took place in India on a single day in 2017, when citizens planted some 66 million trees.
