Land degradation means reduction in the potential of the land to produce benefits from a particular land use under a specified form of land management. Changes in climate are recognized as one of the major factors responsible for land degradation affecting sustained development. Land degradation encompasses change in chemical, physical and biological property of the… Continue reading Impact of Climate Change on Soil and Land Degradation
Impact of Climate Change on Agriculture
Low production: Rise in coconut yields (with some exceptions); reduced fruit and vegetable production. Negative impacts on livestock: Livestock of tropical regions would become more prone to infectious and parasitic diseases. Livestock’s productivity would decline. Indigenous breeds of India like Rathi, Tharparkar, Red Sindhi, etc. would be at danger. Regional impact: According to the Turn… Continue reading Impact of Climate Change on Agriculture
CAUSES OF CLIMATE CHANGE: Anthropogenic
Burning of fossil fuels: People drive cars. Heat and cool their houses. People cook food. All those activities take energy. Burning coal, oil, and gas to generate energy ? Burning these things emit gases into the air. The gases cause the air to heat up. This can change the climate of a place In its… Continue reading CAUSES OF CLIMATE CHANGE: Anthropogenic
CAUSES OF CLIMATE CHANGE: Natural
Solar irradiance Changes in the sun’s energy output would cause the climate to change, since the sun is the fundamental source of energy that drives our climate system. Studies show that solar variability has played a role in past climate changes, a decrease in solar activity is thought to have triggered the Little Ice Age… Continue reading CAUSES OF CLIMATE CHANGE: Natural
All about Greenhouse gases and Effect
Greenhouse Effect The greenhouse effect refers to the rise in the global average temperature of the earth. The greenhouse effect is a process that occurs when gases in Earth’s atmosphere trap the Sun’s heat. This process makes Earth much warmer than it would be without an atmosphere. The greenhouse effect is one of the things… Continue reading All about Greenhouse gases and Effect
Sea water pollution
Seawater Pollution: It is polluted mostly near the coast through the disposal of urban and industrial waste matters into the coastal waters. Causes Discharge of sewage, industrial effluents and toxic chemicals from urban areas and industrial establishment. Discharge of solid waste materials mainly plastics, microbeads, etc. According to UNEP, plastic accounts for 90% of all… Continue reading Sea water pollution
Surface (River) Water Pollution
Surface water includes river, lake and pond water but here only river water pollution is discussed as lake water pollution is discussed separately. Major River Water Pollutants: Sewage Wastes Infectious agents include germs and viruses which causes several types of diseases like typhoid, dysentery, cholera, etc. Plants nutrients and dissolved substances e.g. chemical fertilizers,… Continue reading Surface (River) Water Pollution
Water Pollution: Sources
Water Pollution refers to the deterioration of physical (such as color, odor, turbidity, taste, temperature), chemical (such as acidity, alkalinity, salinity, etc.), and biological (presence of bacteria, coliform MPN, algae, etc.) characteristics of water through natural and anthropogenic processes to such an extent that it becomes harmful to human beings, plants, and animal communities. SOURCES… Continue reading Water Pollution: Sources
EFFECTS OF AIR POLLUTION
Effects on Weather and Climate Air pollution changes our planet’s climate Some types cause global warming to speed up. Others cause global warming to slow down by creating a temporary cooling effect for a few days or weeks. Depletion of Ozone Chlorofluorocarbons attacked and destroyed the ozone layer, producing holes that would allow dangerous… Continue reading EFFECTS OF AIR POLLUTION
INDOOR AIR POLLUTION
Indoor Air Pollution-Meaning: If indoor air is contaminated by smoke, chemicals, smells, or particles. Unlike outdoor air pollution, the effect of indoor air pollution is health-related and less of an environmental issue. Causes: In colder regions, building and heating methods make use of airtight spaces, less ventilation, and energy-efficient heating. Sometimes synthetic building materials… Continue reading INDOOR AIR POLLUTION
