Effects of Natural Disasters Essay

Introduction

Natural disasters range from climatic cataclysms such as droughts, floods, hurricanes and tornadoes to geological catastrophes like earthquakes, volcanoes and tsunamis. Their consequences are both short-term and long-term and lead to either negative or positive consequences on the economy of a country. This effects of natural disasters essay will examine each outcome of such tragedies.

Generally, natural disasters affect the physical infrastructural facilities and lead to a lack of agricultural productivity. They tend to cause the loss of life and damage to property. Various factors influence the effects of natural disasters on a country. Among them are the magnitude of the disaster, the geography of the area affected and recovery efforts directed towards reducing the immediate consequences. Failure to mitigate the short-term economic issues impacts the long-term economic growth of a country.

It can be crucial to understand both causes and effects of natural disasters. This essay, however, will focus on the negative consequences that follow such tragedies.

Effects of Natural Disasters on Natural Resources

The effects of natural disasters on natural resources can be both negative and positive. Natural disasters such as hurricanes and tornadoes dislodge trees causing a reduction in forest cover. Hurricanes and floods also wash away the fertile top soil reducing soil fertility that negatively affects agricultural productivity (Popp 2003, 63). Disasters also lead to the destruction of agricultural resources notably crops and livestock.

Natural disasters such as droughts and floods affect crop and livestock farming thus reducing agricultural production (Bradford & Carmichael, 2006: 56). This phenomenon results to “high food prices products, which in turn affect the economic stability of a region or country” (Maharatna, 1999: 54). Natural disasters also lead to the destruction of wildlife and natural phenomena thus affecting tourism; for instance, storms such as the Tenerife storm in 2005 destroyed ‘El Dedo de Dios’ an important tourist attraction thus affecting tourism

Natural disasters can also cause beneficial effects to a country’s economy. Rich fertile alluvial soils deposited on flood plains are ideal for faming of crops. Additionally, Abbott posits that “Disasters such as volcanic eruptions emit volcanic ash that forms fertile volcanic soils ideal for agriculture” (2004: 342). Volcanic eruptions also lead to the formation of craters that are important tourist attraction.

Effects of Natural Disasters on Physical Infrastructure

Natural disasters such as earthquakes and floods destroy infrastructural facilities such as roads and airports affecting transportation and economic growth. As Temple says, physical infrastructural facilities are important in stimulation of economic growth of any country (1999: 139).

However, natural disasters destroy these structures and thus negatively affect economic growth of a country. Critical infrastructure such as transportation and communication, health systems and energy supply are affected by natural infrastructure (Parfomak, 2005:14). However, efforts geared towards reconstruction and rebuilding of physical infrastructural facilities can help promote return to normalcy.

Impacts of Natural Disasters on Population

Natural disasters have negative effects on population growth of a country. Many lives are lost during natural catastrophes such as tsunamis and floods which reduces the population of a region or a country; a good example is the Japan tragedy which saw thousands of lives lost.

Additionally, Cain laments that the prospects of “a natural disaster occurring causes fear which leads to a decline in birth rate of f the population” (1983: 698). Destruction of natural resources affects the economy leading to low per capita income among the citizens, which in turn influences the fertility rate of a population (Lee, 1985: 635). Low fertility rate contributes to a decline in population growth.

Economic Effects of Natural Disasters

Natural disasters negatively affect important sectors of a country’s economy. Natural disasters affect a country’s energy production stations including oil refineries and nuclear plants leads energy crisis, which results to high oil prices (Noy, 2009: 13).

According to the Congressional Research Service report, “Hurricane Katrina affected oil refineries and pipelines in the U.S. Gulf coast leading to higher oil prices nationally and internationally” (Cashell & Labonte, 2005: 16 ). This led to slower economic growth of the regions hit by the hurricane. Japan is still battling to prevent a nuclear disaster following the recent earthquake and tsunami that rocked the country recently.

Natural disasters also lead to reduced domestic and international trade, which negatively affect the economy. Moreover, natural disasters affect ports and transportation, which lead to reduction of the amount of imports and exports thus affecting trade. Additionally, natural disasters can bring beneficial effects to the economy of a region.

Skidmore and Toya highlight that, natural disasters precede “intensive construction and building activities to bring about recovery” (2002, 148). The locals and the businesses operating in a region affected by the natural disaster are employed in these recovery activities. However, the destruction of property and infrastructure by natural disasters often result to massive unemployment rates.

Effects of Natural Disasters on Human Labor and technology

Skilled human labor is an important element in achieving economic development in any country. Natural disasters like floods and volcanoes cause death and loss of life thereby reducing the human capital of a region and as Skoufas notes, natural disasters also affect training of human capital through the disruption of schools and damage to training facilities (2003: 99).

Damage to property and unemployment lead to reduced family income, which affect education of especially the young people leading to majority of students to drop out of school. Natural disasters adversely affect technological developments of a country. However, natural disasters can stimulate technological innovations to withstand future disasters such as earthquakes. Technological innovations promote economic growth of a country.

Effects of Hurricane Katrina to the U.S Economy

Hurricane Katrina caused damage to many residential property and affected “physical infrastructure like roads and bridges in many states especially Louisiana and Mississippi” (Black & Veatch, 2006: 4). Wastewater disposal systems were affected especially in New Orleans due to damage caused on pipes.

It also affected water supply, electricity and essential healthcare delivery to the affected regions. Transportation of oil products and gas back and forth these regions were affected (Rahman, 2005: 114). The hurricane Katrina affected economy of the states hit by the disaster and the national economy. The U.S. national economic growth declined up to 1.0% because of the effects of the hurricane in these states. However, rebuilding activities will enhance economic growth.

The hurricane disaster affected the energy production centers including the oil refineries in Louisiana. The daily output of these refineries reduced because of the effects of the hurricane leading to a rise in oil and gas prices in the country.

The effects to the ports and oil pipes also contributed to energy crisis experienced during the same period. Due to the destruction of property and industrial facilities by the hurricane, high unemployment rates occurred in these states (Liu, Matt, & Mabanta, 2006: 123). Recovery efforts involve rebuilding the industrial and physical infrastructure and facilities such as schools.

Conclusion

The effects of natural disasters are both short-term including loss of life and damage to property and long-term affecting the economic stability of a region or a country. Damage to infrastructure and energy production centers lead to adverse effects on a country’s economic development. Recovery efforts involving construction and rebuilding of facilities help reverse the effects of disasters and provide employment to the affected people. Other natural disasters such as floods bring beneficial products as sectors such as agriculture improve.
