Climate Change In Cambodia
Climate change in Cambodia presents major challenges for the country. Cambodia is highly vulnerable to the effects of climate change. Extreme weather events will occur more frequently; this includes floods, which already affect 90,000 residents annually, and heatwaves, with Cambodia already having one of the highest temperatures of the world. The temperature has increased since the 1960s by 0.18 °C per decade. It had the 7th lowest emissions in Asia in 2019. Climate change is leading to increased drought in Cambodia, which is having major impacts on the Tonlé Sap and Mekong deltas. These water systems are highly important for water, agriculture and fishing in the country. Cambodia's population is impacted by increasing floods, tropical cyclones and waterborne diseases, and is highly vulnerable due to its high rate of poverty. Greenhouse gas emissions In 2020 Cambodia reported 15.33 mt in emissions and is responsible for 0.04% in 2019 and cumulatively 0.01% of wo ...

Temperature Bar Chart Asia-Cambodia--1901-2020--2021-07-13
Temperature is a physical quantity that expresses quantitatively the perceptions of hotness and coldness. Temperature is measured with a thermometer. Thermometers are calibrated in various temperature scales that historically have relied on various reference points and thermometric substances for definition. The most common scales are the Celsius scale with the unit symbol °C (formerly called ''centigrade''), the Fahrenheit scale (°F), and the Kelvin scale (K), the latter being used predominantly for scientific purposes. The kelvin is one of the seven base units in the International System of Units (SI). Absolute zero, i.e., zero kelvin or −273.15 °C, is the lowest point in the thermodynamic temperature scale. Experimentally, it can be approached very closely but not actually reached, as recognized in the third law of thermodynamics. It would be impossible to extract energy as heat from a body at that temperature. Temperature is important in all fields of nat ...

Climate Change And Infectious Diseases
Global climate change has resulted in a wide range of impacts on the spread of infectious diseases. Like other climate change impacts on human health, climate change exacerbates existing inequalities and challenges in managing infectious disease. It also increases the likelihood of certain kinds of new infectious disease challenges. Infectious diseases whose transmission can be impacted by climate change include Dengue fever, Malaria, Tick-borne disease, Leishmaniasis, Ebola. There is no direct evidence that the spread of COVID-19 is worsened or is caused by climate change, although investigations continue. Documented infectious disease impacts of climate change, include increased malaria and dengue, which are expected to worsen as the global climate changes directly result in extreme weather conditions and higher temperatures. Not only will it propagate their spread, but climate change will probably bring forth new infectious diseases, and change the epidemiology of many exi ...

Climate Change In Vietnam
Climate change in Vietnam is having considerable environmental, economic and social impacts. Vietnam is among the most affected countries by global climate change. A large number of studies show that Vietnam is experiencing climate change and will be severely negatively affected in coming decades. These negative effects include sea level rise, salinity intrusion and other hydrological problems like floods, river mouth evolution and sedimentation. Natural hazards such as cold waves, storm surges will increase in frequency, with negative effects on the country's development, infrastructure and economy. Some issues, such as land subsidence (caused by excessive groundwater extraction) further worsen some of the effects climate change will bring (sea level rise) especially in areas such as the Mekong Delta. The government, NGOs, and citizens have taken various measures to mitigate and adapt to the impact. Background The increase in the concentration of greenhouse gases such as ...

Waterborne Disease And Climate Change
Climate change is expected to increase the severity of most meteorological conditions which will in turn increase the infection area and seasonal duration of waterborne diseases. Climate change, and its effects are already being seen around the globe in warmer water, drought, higher rainfall, and flooding. Related changes in waterborne diseases are already being documented globally and are expected to increase, not only in developing countries but also in already developed countries. Extreme precipitation, storm surges, and flooding are already on the rise due to climate change. These present a large risk to current system capacities and could lead to disruption or failure in the infrastructure. The current trend shows a positive correlation between waterborne diseases and meteorological conditions changing due to climate change. Changes in precipitation and water cycle Climate change is forecast to have substantial effects on the water cycle, with an increase in both frequency and ...

Hydropower In The Mekong River Basin
The estimated hydropower potential of the lower Mekong Basin (i.e., excluding China) is 30,000 MW, while that of the upper Mekong Basin is 28,930 MW. In the lower Mekong, more than 3,235 MW has been realized via facilities built largely over the past ten years, while projects under construction will represent an additional 3,209 MW. An additional 134 projects are planned for the lower Mekong, which will maximize the river's hydropower generating capacity. The single most significant impact—both now and in the future—on the use of water and its management in the Mekong Region is hydropower. Given current development trends in the region, power demands are expected to rise seven percent per year between 2010 and 2030, yielding a substantial and potentially lucrative energy market. Hydropower is the favoured energy option for the Mekong's riparian countries. The development of the Mekong River Basin is highly controversial, and is one of the most prominent components in the discu ...

Lac Tonlé Au Cambodge Vue Par Sentinel 2
Lac is the resinous secretion of a number of species of lac insects, of which the most commonly cultivated is ''Kerria lacca''. Cultivation begins when a farmer gets a stick that contains eggs ready to hatch and ties it to the tree to be infested. Thousands of lac insects colonize the branches of the host trees and secrete the resinous pigment. The coated branches of the host trees are cut and harvested as sticklac. The harvested sticklac is crushed and sieved to remove impurities. The sieved material is then repeatedly washed to remove insect parts and other material. The resulting product is known as seedlac. The prefix ''seed'' refers to its pellet shape. Seedlac, which still contains 3–5% impurity, is processed into shellac by heat treatment or solvent extraction. The leading producer of lac is Jharkhand, followed by the Chhattisgarh, West Bengal, and Maharashtra states of India. Lac production is also found in Bangladesh, Myanmar, Thailand, Laos, Vietnam, parts of C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flooding
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 ...

Representative Concentration Pathway
A Representative Concentration Pathway (RCP) is a greenhouse gas concentration (not emissions) trajectory adopted by the IPCC. Four pathways were used for climate modeling and research for the IPCC fifth Assessment Report (AR5) in 2014. The pathways describe different climate futures, all of which are considered possible depending on the volume of greenhouse gases (GHG) emitted in the years to come. The RCPs – originally RCP2.6, RCP4.5, RCP6, and RCP8.5 – are labelled after a possible range of radiative forcing values in the year 2100 (2.6, 4.5, 6, and 8.5 W/m2, respectively). Since AR5 the original pathways are being considered together with Shared Socioeconomic Pathways: as are new RCPs such as RCP1.9, RCP3.4 and RCP7. Concentrations The RCPs are consistent with a wide range of possible changes in future anthropogenic (i.e., human) GHG emissions, and aim to represent their atmospheric concentrations.Collins, M., ''et al.'': Section 12.3.1.3 The New Concentration Driven RC ...

List Of Countries By Carbon Dioxide Emissions Per Capita
This is a list of countries by carbon dioxide emissions per capita per year. The first section is devoted to emissions based on the production of goods and services within each country (also known as territorial-based emissions). It provides data regarding carbon dioxide emissions from the burning of fossil fuels and cement manufacture but not emissions from land-use, land-use change and forestry (which includes deforestation). Emissions from international shipping or bunker fuels are also not included in national figures, which can make a significant difference for small countries with important ports. The second section provides data regarding emissions based on consumption of goods and services in each country. In addition to the emissions from goods and services produced locally, consumption-based accounting also includes the emissions from the consumption of goods and services produced abroad, i.e. imports, while it excludes emissions from the production of goods a ...
