Indonesia has experienced a series of disasters that have resulted in fatalities, environmental damage and infrastructure such as Jakarta floods, landslides in Banjarnegara and Ponorogo, tornadoes in Surabaya, landslides in Lumajang, tidal floods in Semarang, high waves on the southern sea, even such global disaster like melting ice , extreme storms, heat waves and tornadoes. Disasters occur not only because of climate change which become extreme, but also the environmental damage and the geography of the region itself. Areas with high topography must be vigilant about rainfall because the intensity can trigger landslides when they are not supported by environmental forces (trees with strong roots) to hold them back. Urban areas are prone to floods if they do not have a good drainage and good river management systems and good people’s lifestyles in waste management. In addition, there is a shift in seasons such as a longer dry season, a long rainy season with a small or even sudden extreme intensity.
It is important to educate public in dealing with climate change in the form of adaptation actions (Adaptation to conditions) and mitigation (disaster risk reduction). Climate change is a change in the natural elements of the climate (temperature, humidity, rain, pressure, wind, etc.) in a relatively long time and the natural things of the earth’s stability cycle. The Intergovernmental Panel on Climate Change (IPCC), an international forum, states that the biggest source of climate change is due to increasing global surface temperature. Global warming occurs because of the increasing concentration of greenhouse gases in the atmosphere. Greenhouse gases are naturally obtained from sources of evaporation and eruption, in normal concentrations to warm the earth, but the IPCC in 2007 issued a statement that the main cause of increasing global warming is the human activities that result greenhouse gases. Greenhouse gases will reflect solar radiation back to earth so that the earth’s temperature rises. Greenhouse gases are generated in almost all sectors of activities that use fossil fuels, organic waste, cooling materials in electronic devices. The biggest impact of greenhouse gas come from Carbon dioxide (CO2), Nitro Oxide (NOx), Sulfur Oxide (SOx), Methane (CH4), Chloroflurocarbon (CFC), Hydrofluorocarbon (HFC).
BMKG Surabaya stated the information there was an increase in temperature of 1° C every year in the last 40 years in Surabaya, so it became an early warning to mitigate the reduction of CO2 emissions that could trigger extreme climate change. Indicators of climate change according to the Rencana Aksi Nasional (RAN) towards climate change arranged by BAPPENAS, such as
Climate Change Phenomenon
Sector In Iccsr
Then if we look through global warming in Indonesia in terms of environmental, social, economic, health and cultural aspects, we can describe as follows:
Indonesia and other countries in the world have committed (the Tokyo Protocol 2007) to reduce greenhouse gas emissions by 20%, which has been reduced in the National Action Plan and downgraded to regional and long-term regional development plans. All levels and places and ages can contribute and do not need to wait for command from the government. Experience every year, records of natural events, local wisdom and observations of the environment should be the primary material for carrying out adaptation and mitigation activities to climate change. Mitigation is an effort to reduce greenhouse gas emissions as a response to climate change issues, for example the use of bicycles as a mode of transportation, carbon emission calculation. Adaptation is an effort to increase resilience to the effects of climate change, for example: improving the quality of infrastructure, improving service quality and so on.
Any mitigation actions can be carried out such as:
In Surabaya, ITS as ”eco-campus” has implemented several activities including the application of e-office, waste processing, the use of energy-saving lamps, solar energy, campus bike, vehicle emission testing, utilisation of mass transportation and others. Then schools, offices, industries and other places of course have also implemented environmental policies in the implementation of their operations.
Adaptation actions that can be applied include the following points (www.worldbank.org) :
Climate change and global warming are real in front of us. For our earth which is the one and only, let’s be active and give contribution to our environment as best as we can, no need to wait for command from government. Bring good habits to protect the environment, start from early age and inherit the best lifestyle for next generation.
