Abstract

There have been a lot of geospatial technologies implemented to support disaster management into a more effective way and achieve disaster risk reduction. One of these technologies is the use Volunteered Geographic Information (VGI). VGI refers to the volunteered activities by anyone to create geographic information. The recent development of VGI is obviously supported by the development technology itself such as social media, Global Positioning System (GPS) with acceptable accuracy. In addition, it is also supported by mostly unlimited cloud-based storage as well as smartphones. In the phenomena of natural disater such as flood, landslide, earth quake, tsunami, and other phenomena, the need of geospatial data and the availability in timely manner becomes important and crucial at all disaster management aspects. The availability of geographic information is very much critical at the time the disaster occurs compared to normal situation. Therefore, VGI is necessary in supporting near real time information. In this case, VGI has a key role in disaster management particularly to reduce disaster risk.

Abstract

Pembangunan yang pesat di daerah pesisir menjadikan daerah pesisir beserta jutaan penduduk, infrastruktur, maupun aktivitas ekonomi yang ada memiliki risiko yang meningkat pula terhadap ancaman bahaya pesisir seperti erosi pantai, badai, kenaikan muka air laut dan juga tsunami. Oleh karena itu kesiapsiagaan dan mitigasi menjadi hal penting untuk melindungi dari bencana alam. Dalam hal ini, rekayasa struktur sering kali diimplementasikan dimana dalam proses pembangunannya dapat menyebabkan terganggunya ekosistem laut maupun darat. Alternatif lain yaitu dengan pemanfaatan zona penyangga alami vegetasi pantai. Struktur vegetasi pantai memiliki kemampuan mengurangi gelombang secara langsung dan secara tidak langsung, dapat mengurangi dampak yang ditimbulkan melalui stabilisasi dan pembentukan sedimen. Mangrove sebagai contoh dari vegetasi pantai relatif sering ditemukan di garis depan dalam hal kedudukan atau posisinya terhadap bencana pesisir. Mangrove mampu melemahkan arus gelombang, menangkap sedimen, dan membentuk tanah. Akar dari mangrove dapat menjebak sedimen, manambah tinggi permukaan, dan memberikan perlindungan terhadap kenaikan muka laut. Pada penelitian ini dilakukan studi literatur mengenai peran vegetasi pantai dalam menghadapi berbagai macam ancaman bahaya pesisir. Peran vegetasi pantai tersebut akan diuraikan pada masing-masing bahaya yang dapat mengancam daerah pesisir. Melalui studi ini dapat dilihat bahwa vegetasi pantai dapat memberikan manfaat dalam mengurangi ancaman bahaya pesisir. Oleh karena itu, usaha-usaha dalam melindungi keberadaan vegetasi pantai penting dilakukan karena dapat meminimalisir risiko akibat bahaya yang mengancam.

Abstract

Land use land cover change and forestry play an important role in the global environmental change. Anthropogenic activities in changing the land have caused earth surface change. This change has a role to increase the change of global greenhouse gases in the atmosphere which also causes the increase greenhouse gases emission. Land cover change and forestry are sectors which cause high carbon emission. Therefore, a study in land cover change and estimation of carbon emission becomes important. This study took place in Jambi Province where deforestation has been in a high pace. In 2009 and 2011, the dominant area is dryland agriculture mixed with bush followed by secondary forest, i.e. 25% and 18.6%, respectively (in 2009); and 37.1% and 18.9%, respectively (in 2011). For the secondary forest, the gain was caused by the conversion of dryland agriculture mixed with bush and shrub into secondary forest. The loss of secondary forest is the highest among other forest cover at around 87,765 Ha due to the conversion into bare land and dryland agriculture mixed with bush. Due to land cover change in Jambi Province, the estimation of nett emission in the period of 2009-2011 is 4.8 Mt CO2-eq/year.

Abstract

The development of current massive technology plays an important role in the field of disaster risk reduction and disaster management. In particular, the issue of disruptive technology in which the emerging of new technologies comes with big disruption in many fields. For instance, the development on using satellite imagery big data for disaster management to reduce the disaster risk.The unique characteristics of big data i.e. volume, velocity, and variety stimulate this study to obtain more information on the big data processing and analyze the opportunities and challenges of satellite imagery in the case of disaster risk reduction through literature reviews. The huge amount of data and the ability for real-time analysis provide capabilities on  time series analysis and possitive impact on disaster detection, monitoring, and prediction. However, such technology creates disruption due to the change on using and anlysing the data based on cloud environment. Issues on the technology uses, data security might arise. Nonetheless, the use of satellite imagery big data will remain vastly developed and is able to promote the development of satellite imagery technology.

Abstract

Mangrove ecosystem has high productivity both ecologically and economically. Mangroveecosystems have the ability to store high carbon which is useful in supporting the reduction ofgreenhouse gas emissions. The results of previous studies have shown that mangroveecosystems are able to store carbon three to four times greater than terestrial forests. Most ofthe carbon are stored in the soil. Therefore, ecosystem mangroves have an important role tomitigate climate change. However, mangroves can be effective in supporting the mitigation ofcarbon dioxide emissions if mangrove deforestation rates are low. However, mangroves canstill contribute with great potential when conservation are maintained to increase future carbonstocks through restoration and prevent further emissions from deforestation. Existing data andprior research indicate that mangrove forests are threatened due to mangrove coveragereduction. This is caused by changes in land use. There are many conversions of mangrovesinto cultivation ponds, as well as conversions into agricultural land such as paddy fields andpastures, accompanied by an increase in demand for oil palm which causes land clearing. Inaddition, the population around the coastal area is increasing, resulting in the clearing ofmangrove land for infrastructure development such as road and port construction. In order toreduce the rate of mangrove deforestation, it is necessary to conserve and restore mangroves.By preserving mangrove forests, not only maintain carbon stocks for climate change mitigationbut also facilitate adaptation to climate change such as sea level rise.
