Dominican Republic Environmental Issues
Conservation of Biodiversity Perhaps the most pressing environmental challenge that human population faces is the conservation of biodiversity; the preservation of the great diversity of life-genes, species and ecosystems - which exists in the biosphere of our planet, as well as its mutual interactions with the physical environment. One of the most important focal points of biodiversity in the world is located in the Caribbean region, and in this region, The Hispaniola Island is the most diverse of all the West Indies. However, stress factors such as climate change, fragmentation and degradation of habitat, the invasion of non-native aggressive species, the overexploitation of forest and marine resources and the pollution of water, air and soil, are threatening the planet's biodiversity, thereby endangering its long-term existence. To be able to face the increasing losses caused by humans, in 1992 the world's nations decided to create the Convention on Biological Diversity, sponsored by the United Nations. It is hoped that this agreement can promote the conservation of biodiversity, the sustainable use of its components and the fair and equitable distribution of benefits arising from such use, both in the Dominican Republic and in other signatory nations participating in the Convention. While some species are in the process of extinction due to the aforementioned pressures, others take advantage of the spaces created by humans and spread to new areas. Among the latter are aggressive invasive species that are transported by human actions to places where they were previously not naturally present. Thus, there are many micro-organisms, plants and animals which after propagating and occupying new habitats, become aggressive and result in pests, damaging the environment and threatening many native species that live there naturally. In fact, at present, the invasion of exotic species into previously unoccupied areas is one of the biggest threats to natural life on our planet. Never before in human history was there a biological invasion of such magnitude. For this reason, the prevention and control of invasive species is one of the largest environmental challenges of our era. Deforestation
One of the main causes of deforestation has been forest fires caused by human action. In fact, man has become the leading cause of forest fires, surpassing natural factors such as lightning. People frequently set fires, intentionally or accidentally, thereby altering the structure and composition of forest vegetation. As a result, there are uncontrollable wildfires of unimaginable scales that burn thousands of hectares of tropical rainforests. The Dominican Republic is one of the countries that suffer greatly from the impacts caused by these forest fires. The majority of fires are ignited intentionally for agricultural and livestock purposes, during the driest months of the year. In view of the scale of this problem, it is crucial that the Dominican people pay close attention to the management of these forest fires, in a coherent and integrated manner, with an approach that is mindful of the ecosystem. And in this context, it is important to discuss the approach taken to integrated forest fire management, as it goes far beyond conventional strategies for preventing and extinguishing fires and includes planned actions such as controlled or prescribed burns, community participation, and the enforcement of laws. The challenge now is to implement these promising techniques, to manage, in an integrated and successful manner, the numerous fires that threaten the biodiversity of the Dominican forests and that of the Caribbean region in general. Climate Change Another major challenge facing human beings today -and perhaps the greatest of our times- is known as climate change, which is the variation of the climate caused by human factors. This change may persist for prolonged periods ranging from decades to millennia. At the same time, it can have major impact on life systems that inhabit the Earth. It has already been proven that the increased concentrations of greenhouse gases (GHGs) and aerosols in the atmosphere are caused by emissions of carbon dioxide from burning fossil fuels such as oil and coal. These greenhouse gases trap heat in the atmosphere, resulting in a process of warming of the Earth's surface. Such warming has persisted for at least three decades and is exerting a significant influence on many physical and biological systems on the planet. Some of the consequences of global warming are the melting of glaciers; the rise in sea levels; the bleaching and death of coral reefs; the geographical displacement of species; the increase in forest fires; the increase in soil erosion and the resulting sedimentation downstream; more frequent and severe floods in plains and coastal areas; pests of invasive species; and ultimately, the extinction of species that are unable to adapt in situ and which migrate to more suitable sites. |
