Belize River
The Belize River runs through the center of Belize. It drains more than one-quarter of the country as it winds along the northern edge of the Maya Mountains to the sea just north of Belize City (). The Belize river valley is largely tropical rain forest. Also known as the Old River, the Belize River begins where the Mopan River and Macal River join just east of San Ignacio, Belize (). The Belize River – Mopan River Catchment contains over 45 percent of the population of Belize. The Belize River, in spite of 78 runs or rapids, is passable via the Mopan to the Guatemalan border. It served as the main artery of commerce and communication between the interior and the coast until well into the twentieth century, and has long been associated with forestry, of logwood (for dye) and of mahogany which survives in small stands. Early on, loggers using the river encountered the Maya and had conflicts with them and with the Spaniards. In 1807 there was a request for "arms and amm ...

Belize Town
Belize City is the largest city in Belize and was once the capital of the former British Honduras. According to the 2010 census, Belize City has a population of 57,169 people in 16,162 households. It is at the mouth of the Haulover Creek, which is a distributary of the Belize River. The Belize River empties into the Caribbean Sea from Belize City on the Philip Goldson Highway on the coast of the Caribbean. The city is the country's principal port and its financial and industrial hub. Cruise ships drop anchor outside the port and are tendered by local citizens. The city was almost entirely destroyed in October 1961 when Hurricane Hattie swept ashore. It was the capital of British Honduras (as Belize was then named) until the government was moved to the new capital of Belmopan in 1970. History Belize City was founded as "Belize Town" in 1638 by English lumber harvesters. It had been a small Maya city called Holzuz. Belize Town was ideal for the English as a central post be ...

Cahal Pech
Cahal Pech is a Maya site located near the town of San Ignacio in the Cayo District of Belize. The site was a palatial, hilltop home for an elite Maya family, and though the most major construction dates to the Classic period, evidence of continuous habitation has been dated to as far back as 1200 BCE during the Early Middle Formative period (Early Middle Preclassic), making Cahal Pech one of the oldest recognizably Maya sites in Western Belize. Location The site rests high above the banks of the Macal River and is strategically located to overlook the confluence of the Macal River and the Mopan River. The site is a collection of 34 structures, with the tallest temple being about 25 meters in height, situated around a central acropolis. The site was abandoned in the 9th century CE for unknown reasons. Archaeology The earliest pottery in western Belize is found here. "Emerging information from western Belize suggests that ceramic-using populations may have been in place as ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xunantunich
Xunantunich () is an Ancient Maya archaeological site in western Belize, about 70 miles (110 km) west of Belize City, in the Cayo District. Xunantunich is located atop a ridge above the Mopan River, well within sight of the Guatemala border – which is to the west.Yaeger, Jason.

Chaa Creek
Chaa Creek is a tributary of the Macal River in the Cayo District in western Belize. One of the official gauging stations of the Macal is located near the confluence with Chaa Creek. There are Maya ruins that remain largely unexcavated in the Chaa Creek catchment basin; certain early research was conducted on the archaeology at Chaa Creek in 1997 by Harvard University. Significant pottery finds and other artifacts have been recovered at the Chaa Creek site, which is posited to be a satellite site of Xunantunich. The Chaa Creek Nature Reserve is a noted area for birdwatching. Over 300 species of birds have been sighted there. The underlying geology of this watershed can be characterised as limestone associations of foothills of the Maya Mountains.Arvito, Rosita et al., ''Geology and ecology of the Chaa Creek Nature Reserve'' (2004) See also *Cahal Pech Cahal Pech is a Maya site located near the town of San Ignacio in the Cayo District of Belize.

Slash-and-burn
Slash-and-burn agriculture is a farming method that involves the cutting and burning of plants in a forest or woodland to create a field called a swidden. The method begins by cutting down the trees and woody plants in an area. The downed vegetation, or "slash", is then left to dry, usually right before the rainiest part of the year. Then, the biomass is burned, resulting in a nutrient-rich layer of ash which makes the soil fertile, as well as temporarily eliminating weed and pest species. After about three to five years, the plot's productivity decreases due to depletion of nutrients along with weed and pest invasion, causing the farmers to abandon the field and move to a new area. The time it takes for a swidden to recover depends on the location and can be as little as five years to more than twenty years, after which the plot can be slashed and burned again, repeating the cycle. In Bangladesh and India, the practice is known as jhum or jhoom. Slash-and-burn is a type of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sustainable Agriculture
Sustainable agriculture is farming in sustainable ways meeting society's present food and textile needs, without compromising the ability for current or future generations to meet their needs. It can be based on an understanding of ecosystem services. There are many methods to increase the sustainability of agriculture. When developing agriculture within sustainable food systems, it is important to develop flexible business process and farming practices. Agriculture has an enormous environmental footprint, playing a significant role in causing climate change (food systems are responsible for one third of the anthropogenic GHG emissions), water scarcity, water pollution, land degradation, deforestation and other processes; it is simultaneously causing environmental changes and being impacted by these changes. Sustainable agriculture consists of environment friendly methods of farming that allow the production of crops or livestock without damage to human or natural systems. It ...

Deforestation
Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, a half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. The Food and Agriculture Organization of the United Nations defines deforestation as the conversion of forest to other land uses (regardless of whether it is human-induced). "Deforestation" and "forest area net change" are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a ...

Pesticide
Pesticides are substances that are meant to control pests. This includes herbicide, insecticide, nematicide, molluscicide, piscicide, avicide, rodenticide, bactericide, insect repellent, animal repellent, microbicide, fungicide, and lampricide. The most common of these are herbicides which account for approximately 80% of all pesticide use. Most pesticides are intended to serve as plant protection products (also known as crop protection products), which in general, protect plants from weeds, fungi, or insects. As an example, the fungus '' Alternaria solani'' is used to combat the aquatic weed '' Salvinia''. In general, a pesticide is a chemical (such as carbamate) or biological agent (such as a virus, bacterium, or fungus) that deters, incapacitates, kills, or otherwise discourages pests. Target pests can include insects, plant pathogens, weeds, molluscs, birds, mammals, fish, nematodes (roundworms), and microbes that destroy property, cause nuisance, or spread ...

Nutrient
A nutrient is a substance used by an organism to survive, grow, and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi, and protists. Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures, such as hair, scales, feathers, or exoskeletons. Some nutrients can be metabolically converted to smaller molecules in the process of releasing energy, such as for carbohydrates, lipids, proteins, and fermentation products (ethanol or vinegar), leading to end-products of water and carbon dioxide. All organisms require water. Essential nutrients for animals are the energy sources, some of the amino acids that are combined to create proteins, a subset of fatty acids, vitamins and certain minerals. Plants require more diverse minerals absorbed through roots, plus carbon dioxide and oxygen absorbed through leaves. Fungi live on dead or living organic matter and meet nutrient needs from their h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sediment
Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles. For example, sand and silt can be carried in suspension in river water and on reaching the sea bed deposited by sedimentation; if buried, they may eventually become sandstone and siltstone ( sedimentary rocks) through lithification. Sediments are most often transported by water ( fluvial processes), but also wind (aeolian processes) and glaciers. Beach sands and river channel deposits are examples of fluvial transport and deposition, though sediment also often settles out of slow-moving or standing water in lakes and oceans. Desert sand dunes and loess are examples of aeolian transport and deposition. Glacial moraine deposits and till are ice-transported sediments. Classification Sediment can be classified based on its grain size, grain s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Quality
Water quality refers to the chemical, physical, and biological characteristics of water based on the standards of its usage. It is most frequently used by reference to a set of standards against which compliance, generally achieved through treatment of the water, can be assessed. The most common standards used to monitor and assess water quality convey the health of ecosystems, safety of human contact, extend of water pollution and condition of drinking water. Water quality has a significant impact on water supply and oftentimes determines supply options. Categories The parameters for water quality are determined by the intended use. Work in the area of water quality tends to be focused on water that is treated for potability, industrial/domestic use, or restoration (of an environment/ecosystem, generally for health of human/aquatic life). Human consumption Contaminants that may be in untreated water include microorganisms such as viruses, protozoa and bacteria; inorg ...
