Deforestation In Haiti
Deforestation is a complex and intertwined environmental and social problem in Haiti. The most-recent national research on charcoal estimates that approximately 946,500 metric tons of charcoal are produced and consumed annually in Haiti, making it the second-largest agricultural value chain in the country and representing approximately 5% of GDP. Dynamics and impact The rapid deforestation of Haiti began during the colonial period, facilitated by slavery of captive Africans, and was intensified when coffee was introduced in 1730. Upland forests were cleared and fifty years later, a quarter of the colony's land was under coffee. The system of plantation monoculture and clean-cultivation between rows of coffee, indigo, tobacco, and sugarcane exhausted soil nutrients and led to rapid erosion. Following the Haitian Revolution, the government was forced to export timber throughout the 19th century to pay off a 90 million franc indemnity to France due to French claims of lost prope ...

Haiti Deforestation
Haiti, officially the Republic of Haiti, is a country on the island of Hispaniola in the Caribbean Sea, east of Cuba and Jamaica, and south of the Bahamas. It occupies the western three-eighths of the island, which it shares with the Dominican Republic. Haiti is the third largest country in the Caribbean, and with an estimated population of 11.4 million, is the most populous Caribbean country. The capital and largest city is Port-au-Prince. Haiti was originally inhabited by the Taíno people. In 1492, Christopher Columbus established the first European settlement in the Americas, La Navidad, on its northeastern coast. The island was part of the Spanish Empire until 1697, when the western portion was ceded to France and became Saint-Domingue, dominated by sugarcane plantations worked by enslaved Africans. The 1791–1804 Haitian Revolution made Haiti the first sovereign state in the Caribbean, the second republic in the Americas, the first country in the Americas to officially a ...

Port-au-Prince
Port-au-Prince ( ; ; , ) is the Capital city, capital and List of cities in Haiti, most populous city of Haiti. The city's population was estimated at 1,200,000 in 2022 with the metropolitan area estimated at a population of 2,618,894. The metropolitan area is defined by the IHSI as including the Communes of Haiti, communes of Port-au-Prince, Delmas, Ouest, Delmas, Cité Soleil, Tabarre, Carrefour, Ouest, Carrefour, and Pétion-Ville. The city of Port-au-Prince is on the Gulf of Gonâve: the bay on which the city lies, which acts as a natural harbor, has sustained economic activity since the civilizations of the Taíno. It was first incorporated under Saint-Domingue, French colonial rule in 1749. The city's layout is similar to that of an amphitheater; commercial districts are near the water, while residential neighborhoods are located on the hills above. Its population is difficult to ascertain due to the rapid growth of slums in the hillsides above the city; however, recent ...

Biodiversity Loss
Biodiversity loss happens when plant or animal species disappear completely from Earth (extinction) or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in Biodiversity, biological diversity in a given area. The decrease can be temporary or permanent. It is temporary if the damage that led to the loss is reversible in time, for example through ecological restoration. If this is not possible, then the decrease is permanent. The cause of most of the biodiversity loss is, generally speaking, human activities that push the planetary boundaries too far. These activities include habitat destruction (for example deforestation) and land use intensification (for example monoculture farming). Further problem areas are Air pollution, air and water pollution (including nutrient pollution), over-exploitation, Invasive alien species, invasive species and climate change. Many scientists, along with the ''Global Assessment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old-growth Forest
An old-growth forest or primary forest is a forest that has developed over a long period of time without disturbance. Due to this, old-growth forests exhibit unique ecological features. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. One-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitats that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree heights and diameters, and diverse tree species and classes and sizes of woody debris., the world has of primary forest ...

Desertification
Desertification is a type of gradual land degradation of Soil fertility, fertile land into arid desert due to a combination of natural processes and human activities. The immediate cause of desertification is the loss of most vegetation. This is driven by a number of factors, alone or in combination, such as drought, climatic shifts, tillage for agriculture, overgrazing and deforestation for fuel or construction materials. Though vegetation plays a major role in determining the Soil biology, biological composition of the soil, studies have shown that, in many environments, the rate of erosion and runoff decreases exponentially with increased vegetation cover. Unprotected, dry soil surfaces blow away with the wind or are washed away by flash floods, leaving infertile lower soil layers that bake in the sun and become an unproductive hardpan. At least 90% of the inhabitants of drylands live in Developing country, developing countries, where they also suffer from poor economic and s ...

Irrigation
Irrigation (also referred to as watering of plants) is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetation, revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irrigation, is the olde ...

Topsoil
Topsoil is the upper layer of soil. It has the highest concentration of organic matter and microorganisms and is where most of the Earth's biological soil activity occurs. Description Topsoil is composed of mineral particles and organic matter and usually extends to a depth of 5-10 inches (13–25 cm). Together these make a substrate capable of holding water and air which encourages biological activity. There are generally a high concentration of roots in topsoil since this is where plants obtain most of their vital nutrients. It also plays host to significant bacterial, fungal and entomological activity without which soil quality would degrade and become less suitable for plants. Bacteria and fungi can be essential in facilitating nutrient exchange with plants and in breaking down organic matter into a form that roots can absorb. Insects also play important roles in breaking down material and aerating and rotating the soil. Many species directly contribute to the he ...

Soil Erosion
Soil erosion is the denudation or wearing away of the Topsoil, upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, Atmosphere of Earth, air (wind), plants, and animals (including humans). In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, Aeolian erosion, wind (aeolian) erosion, Zoogenic erosion, zoogenic erosion and anthropogenic erosion such as tillage erosion. Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing a serious loss of topsoil. The loss of soil from Agricultural land, farmland may be reflected in reduced crop production potential, lower surface water quality and damaged drainage networks. Soil erosion could also cause sinkholes. Human activities have increased by 10–50 times the rate at which erosion is occurring world-wide. Exc ...

Pollarding
Pollarding is a pruning system involving the removal of the upper branches of a tree, which promotes the growth of a dense head of foliage and branches. In ancient Rome, Propertius mentioned pollarding during the 1st century BCE. The practice has occurred commonly in Europe since medieval times, and takes place today in urban areas worldwide, primarily to maintain trees at a determined height or to place new shoots out of the reach of grazing animals. Traditionally, people pollarded trees for one of two reasons: for fodder to feed livestock or for wood. Fodder pollards produced "pollard hay" for livestock feed; they were pruned at intervals of two to six years so their leafy material would be most abundant. Wood pollards were pruned at longer intervals of eight to fifteen years, a pruning cycle tending to produce upright poles favored for fencing and boat construction. Supple young willow or hazel branches may be harvested as material for weaving baskets, fences, and garden cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
