A resource is any material that is available to us in our surroundings that is economically viable, technologically accessible, and culturally sustainable and that helps us meet our needs and desires. Utility or usability is something which makes any material resource.

Types of Resources

Natural

Human Made

Human

Natural Resources:-Natural resources are those resources that are drawn from nature and it is used without much modifications.

Natural resources are further divided into renewable and non renewable resources.

Renewable Resources:- Resources which get renewed and recharged quickly are called renewable resources. Some of these are unaffected by human activities because the are unlimited in quality, such as wind energy and solar energy.

Non Renewable Resources:- Resources which are limited and can be exhausted by human activities are known as non renewable resources, it could take thousands of years to regenerate and recharge. Petroleum,coal and natural gas are some examples of non renewable resources.

Human Made Resources

Natural material sometimes only can be used as resources after changing them from their original state. Buildings, bridges, roads, machines, and automobiles are examples of human-made resources derived from natural resources.

Human Resources

If people have the necessary knowledge, skills, technology, and resources, they can maximise the use of the natural world to produce more resources.That is why people are a unique resource. Human resources are people. People become a precious resource with the help of education and health.

Disasters is an undesirable phenomenon resulting from forces that are largely outside human control. Disasters are viewed as a consequence of natural forces but natural forces are not only causes of disasters. Disasters are also caused by some human activities.

Natural Disasters

Natural disasters are relatively sudden and cause large scale, widespread death, loss of property and disturbance to social system and life over which people have a little or no control.

Classification of Natural Disasters

• Atmospheric :- Atmospheric natural disasters includes Lightning, Tornadoes,Drought, Heat wave etc.

• Terrestrial:- Terrestrial disasters includes earthquake, landslides, avalanches etc.

• Aquatic:- Aquatic natural disasters includes flood, tidal waves, storm surge, tsunami etc.

• Biological:- Biological disasters includes fungal, bacterial and viral diseases such as bird flu, dengue etc.

Man-Made Disasters

Man-made disasters are usually the result of things going wrong in our society. They include: blackouts, hazardous material spills, air pollution, house fires, radiation leaks, food or water contamination, and industrial chemical releases.

Effects of Disasters on Country

• A disaster that occurs in a country will cause a decrease in productivity, which in turn will cause a decline in economic growth in that country.

• A disaster results in huge economic loss due to destruction of property, human settlements and infrastructure etc.

• The disaster results in displacement of people, and displaced population often face several challenges in new settlements, in this process poorer becomes more poor.

• After natural disasters, food and other natural resources like water often becomes scarce resulting into food and water scarcity.
