Disaster a result Humans

The frequency of climate and weather-related disasters in Indonesia continued to increase in the last 10 years. Climate change is often the scapegoat. However, actual environmental management mistakes played a major role towards increasing frequency of disasters.
Review National Disaster Management Agency (BNPB) in 2011 states, the trend of disasters in Indonesia increased from year to year. If in 2002 only recorded 190 disasters, in 2010 there were 930 incidents. In fact, the 2009 incident occurred 1954.

Of the total occurrence of the disaster, almost 79 percent is hydro-meteorological disasters, ie weather-related disasters and climate. These disasters include floods, drought, landslide, tornado, forest and land fires and tidal waves.
Head of Data Information and Public Relations Sutopo BNPB Purwo Nugroho said, in 2002 the frequency of hydro-meteorological disasters in Indonesia, which recorded 134 incidents. Year 2010 to 736 incidents. In 2009 the incidence increased until 1234.
Not only increase in frequency, impact and extent of hydro-meteorological disasters has also increased. The number of hydro-meteorological disaster victims in Indonesia that killed over the last eight years to reach 4936 people, as many as 17.7 million people are suffering and displaced, hundreds of thousands of homes were damaged, and more than 2.5 million homes inundated. The number of these victims is relatively small compared with deaths from geological disasters, like earthquakes and tsunamis, which ranges from 200,000 people in the same period.
In the report of the Global Humanitarian Forum (The Anatomy of Silent Crisis, 2009) mentioned, hydro-meteorological disasters will be the biggest threat to humans in the coming years. The report candidly pointed to climate change as the cause.
Is it true that only increased hydro-meteorological disasters caused by climate change?
Report Intergovernmental Panel on Climate Change (IPCC) shows, the global climate has changed. Effect of climate change causing changes in rainfall patterns. Not only the thick rain of change, intensity, duration, and distribution of rainfall is also changing. Global climate change is also strongly influence the flow pattern changes, such as decreasing tendency of annual rainfall.
Globally, the annual rainfall continues to increase in area middle and high latitudes in the northern hemisphere, namely 0.5 to 1 percent per decade, except in East Asia. In subtropical areas, average precipitation decreases about 0.3 percent per decade, whereas in the tropics increased from 0.2 to 0.3 percent per decade during the 20th century. The majority occurred in the northern hemisphere. The change in rainfall in the southern hemisphere is not known in a comprehensive manner.
Sutopo said some small-scale studies have been carried out in tropical regions in the southern hemisphere, like in Indonesia. Global climate change has brought about changes in the pattern of the local season.
On average amount of rain in the rainy season (October to March in Java) is 80 percent of total annual rainfall. Changes in the pattern occurs with increasing season long dry season and increasing the ratio of the amount of rainfall during the rainy season to dry season, which rose above 80 percent. This is aggravated by a decline in the total accumulation of annual rainfall is persistent in almost all parts of Indonesia in the last five decades so that the potential for reduced water shed.
In addition, the earth's temperature rose 0.7 C in 100 years. "In theory, this increases the evaporation temperature increases. The water content in the air increases. Stability of disturbed air thus more unstable. As a result, the symptoms of a more dynamic weather. Extreme conditions can be more frequent, "said Hidayat Pawitan, climate change experts from the Institut Pertanian Bogor.
