Global Warming Even though some people do not accept that the average temperature of the earth has risen, it is on record that human actions have contributed to more greenhouse gasses in the atmosphere.

As a result, there are warmer temperatures, often resulting in more dryness and bush fires often causing drought conditions. EFFECTS OF DROUGHTS Diminished crop growth or yield productions and carrying capacity for livestock Dust bowls, themselves a sign of erosion, which further erode the landscape Dust storms, when drought hits an area suffering from desertification and erosion Famine due to lack of water for irrigation Habitat damage, affecting both terrestrial and aquatic wildlife Hunger, drought provides too little water to support food crops.

Desalination — of sea water for irrigation or consumption. For instance, analysis of water usage in Yemen has revealed that their water table underground water level is put at grave risk by over-use to fertilize their Khat crop. Land use — Carefully planned crop rotation can help to minimize erosion and allow farmers to plant less water-dependent crops in drier years.

Outdoor water-use restriction — Regulating the use of sprinklers, hoses or buckets on outdoor plants, filling pools, and other water-intensive home maintenance tasks. Rainwater harvesting — Collection and storage of rainwater from roofs or other suitable catchments.

Recycled water — Former wastewater sewage that has been treated and purified for reuse. Such disasters are caused by microorganisms that cause epidemics.

These have spread due to man-made conditions. Most of these have been infectious diseases such as malaria, plague, diphtheria, tuberculosis and influenza. People can control the spread of these diseases by ensuring hygienic conditions and taking preventive measures. The government has taken a number of steps to contain the spread of these diseases such as fumigation to control the spread of the malarial mosquito.

Chemical and radioactive leakages are also the result of human error and result in far reaching damages. A chemical accident is the unintentional release of one or more hazardous substances which could harm human health or the environment.

Chemical hazards are systems where chemical accidents could occur under certain circumstances. Protective clothing: Clothing reduces the risk of mosquito biting if the cloth is sufficiently thick or loosely fitting. Long sleeves and trousers with stockings may protect the arms and legs, the preferred sites for mosquito bites.

Schoolchildren should adhere to these practices whenever possible. Mats, coils and aerosols: Household insecticidal products, namely mosquito coils, pyrethrum space spray and aerosols have been used extensively for personal protection against mosquitoes. Electric vaporizer mats and liquid vaporizers are more recent additions which are marketed in practically all urban areas. Repellents: Repellents are a common means of personal protection against mosquitoes and other biting insects.

These are broadly classified into two categories, natural repellents and chemical repellents. This means being prepared for disasters, fighting disasters effectively, ensuring the safety of life during disasters and helping in rebuilding society after the disaster. When a disaster strikes a society, external help is usually needed in the form of aid to cope with its impact.

Find an open area away from tall building, trees or electric poles. Do not stand near tall buildings, trees or electric pole.

The construction of dams creates a huge water reservoir in which a large portion of land is submerged. Thus, these dams cause excess water pressure in the micro-cracks and fissures in the ground near or under the reservoir. Due to this excess pressure, the water seeps into the ground and lubricates the rocks.

In the worst scenario, when the water pressure is very high, the water reaches the fault planes and lubricates them. This lubrication reduces friction between the tectonic plates, thereby causing the slipping of plates over one another. Hence, in this way dams construction can trigger an earthquake.
