thanks Fadia W Alazawi. thats gonna be useful.

In most of the cases, LU change is directly linked with natural hazards from unplanned urbanization to floods. @Fadia W Alazawi  has referred a good link.

thank you Asmat Ali. I want to know , Is there any methodology for that?  a method to find a significant relation

In hill areas deforestation causes removal of natural barrier for minimizing the bank erosion due to flash floods especially along river banks. Further the hill slopes having less vegetation may witness more erosion and mass wasting as well.

In coastal regions large scale cutting of forests (for construction of ports and development of Industrial areas)  removes the natural barrier to tsunami.

Dear Mohammad Ali Nezammahalleh,

I think it is better to look at your country's context. Select three different areas geographically located far from each other where natural hazards have occurred in the past 5-10 years . Carry out LU change analysis/mapping.  Now relate the data of natural hazards to these LU changes. You may find interesting relationships. 

Good Luck

An example would be the use of water by the oranges industry in Florida,

USA.  To prevent freezing of the oranges, the farmers, pump large amounts of

water and spray the water on the fruit trees in winter.  the result is a temporary

lowering of the aquifer, and the resultant production sinkholes due to loss of

cavern roof support.   Typically sinkholes form at 5 to 6 per year in Florida,

but in one recent year 130 sinkholes formed after spraying oranges to

keep them from freezing.

Dear Aniruddha Uniyal

 I have downloaded that. thank you for that useful paper.

Dear Asmat Ali

your idea is excellent. that can be applicable.

thank you so much.

Dear Michael Clark

thank you, this is good example for further studies.

One of the natural hazards is landslide which apart from natural causes as erosion, rainfall, earthquakes, geological factors and external loading is caused by removal of vegetation, interference with, or changes to, natural drainage, modification of slopes by construction of roads, railways, buildings, etc, and mining and quarrying.

Another natural hazard is urban flooding mainly changing land use of flood plain by construction of building and thus narrowing channel which results in restriction of water flow ultimately consequent upon flooding.

I guess another example other than landslide is flooding. It si very common in India to see settlements within a flood plan of the river. Sometime human encroachment in flood plain is not limited to agriculture but land is reclaimed (partly) and permanent settlements are coming up, which is heavily impacted by floods during rain.

Regarding the methodology to do such an assessment try using thematic integration using GIS. that can be one of the simplest indication.

In North Queensland, Australia, a number of cyclones over the past few years have affected cities including Innisfail, Cardwell, Mission beach and Cairns. The destruction caused by cyclone Yasi in January 2011 was enough to leave some coastal communities just north of Cardwell, effectively deserted. While planning regulations haven't yet led to the re-zoning of these areas, there is a push from some parts of the community to prevent re development in these areas.

Most of the damage at Cardwell was caused by the storm surge associated with the cyclone, instead of high winds. The storm surge picked up boulders from the sea wall and threw them through the front of people's houses. Without the sea wall though, beach erosion would cause the beach to recede quite quickly, eventual causing people's houses to be undermined. There are changes to the local land use and development planning policy being reviewed now.

thanks all

these are good ideas and examples for research

Land use change can have a deleterious effect on the environment like adding a new Walmart. Creating retaining  ponds which captures pollution run off gives a chance for draining water  to reduce pollutants into mainstreams and rivers

The relation of hazard and land use change can be reflected through migration of communities from the area ( Socio-economic dynamics). Diversified changing land use scenario which was not prevailing earlier. quantitative analysis of fellow lands. and mapping of new emerging hazards and land use pattern.

If we continue to cut down all of the Amazon and the Congo, we will find what it is

like to be gasping for oxygen.

i just published a paper about land use change and in particular change in the artificial drainage network and an example of the changes in network saturation, as an example of the possible effects on flood risk...we anyway focused on the changes in the network due to urbanization and how to detect the changes in the network drainage density and water storage... 

I agree, even now a days urban changes without planning are more towards infrastructure collapse.

The dessimation of the American Indians after 1492 due to the Spanish

introducing European diseases to the Americas changed the land use from

agricultural to overgrown forests.  The result was a drop in global 

temperatures leading to the two coldest years ever recorded in 1683,

and in 1684.  The rivers froze over between 1540 ( Coronado ) and

1720 ( last recorded ice cover )  at Albuquerque N.M. USA.

After 1492, European diseases killed off over 95% of all of the 

Native Americans in North, Central, and South America, with a dramatic

land use change from agricultural and continuous underbrush burning,

to overgrown, dense forests that keep the snow insulated far longer

in the spring, and lowers average global temperatures.  In less than

191 years after Columbus first came to the Americas, the temperature

had dropped to record lows due to land use changes due to 

95% human die off.

thank you all researchers. these are very useful answers
