Environmental Issues In Bangladesh
Bangladesh, with an area of 147,570 km2, features a flood plain landscape and several river systems throughout the country. This landscape provides the major natural resources of water, land, fisheries, forests, and wildlife. The country currently faces several environmental issues which threaten these resources, including groundwater metal contamination, increased groundwater salinity, cyclones and flooding, and sedimentation and changing patterns of stream flow due to watershed mismanagement. Some of these, such as the changing patterns of stream flow and presence of lead in groundwater, can be directly correlated with human activity and industrial processes, while others, such as cyclones and flooding are naturally occurring issues. Many of these issues are further exacerbated by climate change, which causes increased occurrence of storms and cyclones and rising sea levels. According to the Notre Dame Global Adaptation Index, Bangladesh is the 43rd most vulnerable country t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Himalayas From Bangladesh
The Himalayas, or Himalaya (; ; ), is a mountain range in Asia, separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has some of the planet's highest peaks, including the very highest, Mount Everest. Over 100 peaks exceeding in elevation lie in the Himalayas. By contrast, the highest peak outside Asia (Aconcagua, in the Andes) is tall. The Himalayas abut or cross five countries: Bhutan, India, Nepal, China, and Pakistan. The sovereignty of the range in the Kashmir region is disputed among India, Pakistan, and China. The Himalayan range is bordered on the northwest by the Karakoram and Hindu Kush ranges, on the north by the Tibetan Plateau, and on the south by the Indo-Gangetic Plain. Some of the world's major rivers, the Indus, the Ganges, and the Tsangpo–Brahmaputra, rise in the vicinity of the Himalayas, and their combined drainage basin is home to some 600 million people; 53 million people live in the Himalayas. The Himalayas have pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flooding After 1991 Cyclone
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding, for example land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees, and larger environmental issues such as climate change and sea level rise. In particular climate change's increased rainfall and extreme weather events increases the severity of other causes for flooding, resulting in more intense floods and increased flood risk. Flooding may occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting in some of t ...

Forest Landscape Integrity Index
The Forest Landscape Integrity Index (FLII) is an annual global index of forest condition measured by degree of anthropogenic modification. Created by a team of 48 scientists, the FLII, in its measurement of 300m pixels of forest across the globe, finds that ~17.4 million km2 of forest has high landscape-level integrity (with a score from 9.6–10), compared to ~14.6 million with medium integrity (6–9.6) and ~12.2 million km2 with low integrity (0–6). The FLII finds that most remaining high-integrity forest landscapes are found in Canada, Russia, Rocky Mountains, Alaska, the Amazon, the Guianas, southern Chile, Central Africa, and New Guinea. Low integrity forests, on the other hand, are found in Western and Central Europe, the American Southwest, South-East Asia west of New Guinea, the Andes, much of China and India, the Albertine Rift, West Africa, Mesoamerica, and the Atlantic Forests of Brazil. The results are meant to help decision-makers at all levels achieve their comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Change Mitigation
Climate change mitigation is action to limit climate change by reducing Greenhouse gas emissions, emissions of greenhouse gases or Carbon sink, removing those gases from the atmosphere. The recent rise in global average temperature is mostly caused by emissions from fossil fuels burning (coal, oil, and natural gas). Mitigation can reduce emissions by energy transition, transitioning to sustainable energy sources, energy conservation, conserving energy, and Efficient energy use, increasing efficiency. In addition, can be carbon dioxide removal, removed from the atmosphere by carbon sink, enlarging forests, Wetland restoration, restoring wetlands and using other natural and technical processes, which are grouped together under the term of carbon sequestration. Solar energy and wind power have the highest climate change mitigation potential at lowest cost compared to a range of other options. Variable availability of sunshine and wind is addressed by energy storage and improved elec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Deforestation In Nepal
Deforestation in Nepal has always been a serious issue, which has a severe effect on the lives of poor people. In the past, Nepal was a widely forested nation. However now with the requirement for the extension of rural areas, migration of hills people to the plains, the developing regional interest for timber, and the local residents dependence on firewood as the essential source of energy, less than 30% of the nation's forest cover remains. Due to the continuous deforestation in Nepal, many people and creatures are dying. Around 70 percent of the people in Nepal work in agriculture, even if it is difficult to farm in the prevailing unfavourable weather conditions. Rate of deforestation Between 1990 and 2000, Nepal lost an average of 91,700 hectares of forest per year. This amounts to an average annual deforestation rate of 1.90%. However, between 2000 and 2005, the rate of deforestation decreased by 28.9% to 1.35% per year. In total, between 1990 and 2005, Nepal lost 24.5% of i ...

Soil Composition
Soil, also commonly referred to as earth or dirt, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Some scientific definitions distinguish ''dirt'' from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three-state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists regard soil as an ecosystem. Most so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soil Erosion
Soil erosion is the denudation or wearing away of the 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, air (wind), plants, and animals (including humans). In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind (aeolean) 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 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. Excessive (or accelerated) erosion causes both "on-site" and "off-site" problems. On- ...

Intergovernmental Panel On Climate Change
The Intergovernmental Panel on Climate Change (IPCC) is an intergovernmental body of the United Nations. Its job is to advance scientific knowledge about climate change caused by human activities. The World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) established the IPCC in 1988. The United Nations endorsed the creation of the IPCC later that year. It has a secretariat in Geneva, Switzerland, hosted by the WMO. It has 195 member states who govern the IPCC. The member states elect a bureau of scientists to serve through an assessment cycle. A cycle is usually six to seven years. The bureau selects experts to prepare IPCC reports. It draws the experts from nominations by governments and observer organisations. The IPCC has three working groups and a task force, which carry out its scientific work. The IPCC informs governments about the state of knowledge of climate change. It does this by examining all the relevant scientific literature ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storm Surge
A storm surge, storm flood, tidal surge, or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low-pressure weather systems, such as cyclones. It is measured as the rise in water level above the normal tidal level, and does not include waves. The main meteorological factor contributing to a storm surge is high-speed wind pushing water towards the coast over a long fetch. Other factors affecting storm surge severity include the shallowness and orientation of the water body in the storm path, the timing of tides, and the atmospheric pressure drop due to the storm. There is a suggestion that climate change may be increasing the hazard of storm surges. Some theorize that as extreme weather becomes more intense and sea level rises due to climate change, storm surge is expected to cause more risk to coastal populations. Communities and governments can adapt by building hard infrastructure, like surge barriers, soft infrastructure, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
