Abstract: Many informal settlements in Indonesia have been unable to survive, this is due to changes that occur in the neighborhood. This change resulted in the not surviving of informal settlements, but this did not affect the informal settlements in the city of Palangkaraya, settlements on the banks of the Kahayan river were even more developed, and began to develop towards the mainland.As climate change and the global environment increase, there is a tendency for people to conceptualize adaptation in residential buildings as a process of survival and how adaptation is practiced by people who face the negative impacts of climate change, for example in informal settlements on the Kahayan river bank, where residents adapt to building their homes to be able to withstand environmental changes. Where the neighborhood is located there are tides of the river, as well as other environmental factorsThis study is to find out how the Kahayan River settlement communities can survive, with changes that occur in the environment by analyzing using 6 strategies in building adaptation, namely: Adjustable, Versatile, Refitable, Convertible, Scalable, and Movable (Robert Schmid, 2009). Adaptation that occurs in these settlements, namely on building houses that follow climate change, times, and the environment.Keyword: Informal Settlements, Kahayan River Edge, Adaptation, Transformation.Abstrak: Permukiman Informal di Indonesia banyak yang sudah tidak dapat bertahan, hal ini di karenakan adanya perubahan yang terjadi di lingkungan permukiman tersebut. Perubahan ini berakibat tidak bertahannya permukiman informal, namun hal ini tidak mempengaruhi permukiman informal di Kota Palangkaraya, permukiman yang berada di tepi sungai kahayan ini malah semakin berkembang, dan mulai berkembang menuju ke daratan.Seiring dengan meningkatnya perubahan iklim dan lingkungan global, ada kecenderungan masyarakat untuk membuat konsep adaptasi pada bangunan rumah tinggal sebagai proses untuk bertahan dan bagaimana adaptasi dipraktikkan oleh orang-orang yang menghadapi dampak negatif perubahan iklim, sebagai contoh pada permukiman informal yang berada di tepi sungai Kahayan, di mana warga beradaptasi pada bangunan rumah mereka untuk dapat bertahan terhadap perubahan lingkungan. Di mana lingkungan permukiman ini terdapat pasang surut air sungai, serta faktor lingkungan lainnya.Penelitian ini untuk mengetahui cara masyarakat permukiman tepi Sungai Kahayan dapat bertahan, dengan perubahan yang terjadi di lingkungan dengan menganalisa menggunakan 6 strategi dalam adaptasi bangunan, yaitu: Adjustable, Versatile, Refitable, Convertible, Scalable, dan Movable (Robert Schmid, 2009). Adaptasi yang terjadi pada permukiman ini, yaitu pada bangunan rumah yang mengikuti perubahan iklim, jaman, dan lingkungan.Kata Kunci: Permukiman Informal, Tepi  Sungai Kahayan, Adaptasi, Transformasi.

Pluvial flooding in Badalona (Spain) occurs during high rainfall intensity events, which in the future could be more frequent according to the latest report from the Intergovernmental Panel on Climate Change (IPCC). In this context, the present study aims at quantifying the potential impacts of climate change for the city of Badalona. A comprehensive pluvial flood multi risk assessment has been carried out for the entire municipality. The assessment has a twofold target: People safety, based on both pedestrians’ and vehicles’ stability, and impacts on the economic sector in terms of direct damages on properties and vehicles, and indirect damages due to businesses interruption. Risks and damages have also been assessed for the projected future rainfall conditions which enabled the comparison with the current ones, thereby estimating their potential increment. Moreover, the obtained results should be the first step to assess the efficiency of adaptation measures. The novelty of this paper is the integration of a detailed 1D/2D urban drainage model with multiple risk criteria. Although, the proposed methodology was tested for the case study of Badalona (Spain), it can be considered generally applicable to other urban areas affected by pluvial flooding.

Abstract Climate change is likely to cause higher temperatures and alterations in precipitation patterns, with potential impacts on water resources. One important issue in this respect is inflow to drinking water reservoirs. Moreover, deteriorating infrastructures cause leakage in water distribution systems and urbanization augments water demand in cities. In this paper, a framework for assessing the combined impacts of multiple trends on water availability is proposed. The approach is focused on treating uncertainty in local climate projections in order to be of practical use to water suppliers and decision makers. An index for water availability (WAI) is introduced to quantify impacts of climate change, population growth, and ageing infrastructure, as well as the effects of implementing counteractive measures, and has been applied to the city of Bergen, Norway. Results of the study emphasize the importance of considering a range of climate scenarios due to the wide spread in global projections. For the specific case of Bergen, substantial alterations in the hydrological cycle were projected, leading to stronger seasonal variations and a more unpredictable water availability. By sensitivity analysis of the WAI, it was demonstrated how two adaptive measures, increased storage capacity and leakage reduction, can help counteract the impacts of climate change.

Climate change is no longer a debate about its existence but already a problem shared between communities, between agencies, between countries even global for handling serious because so many aspects of life and the environment is affected, especially for communities in coastal environments This climate change is a threat to the Earth, because it can affect all aspects of life and will damage the balance of life of Earth Climate change happens slowly in a fairly long period of time and it is a change that is hard to avoid. These Phenomena will give effect to the various facets of life. Semarang as areas located to Java and bordering the Java Sea are at high risk exposed to the impacts of climate change Also not a few residents of the city of Semarang who settled in the northern part of the city of Semarang and also have a livelihood as farmers/peasants and fishermen Many industrial centers or attractions that are prone to impacted by climate change. Thus, the anticipation of climate change on resources support neighborhood of fishermen in the coastal area of Tanjungmas Semarang interesting for further review. This study aims to find out more the influence of climate change on the environment of fishing identify potential danger due to the impacts of climate change on coastal areas of Tanjungmas Semarang The research was conducted through surveys, interviews and field observation without a list of questions to obtain primary and secondary data As for the analysis undertaken, namely the analysis of climate change on the coastal environment, the analysis of productivity of fishermen as well as the analysis of the likelihood of disaster risk at the coast due to climate change. From the results of the study the occurrence of sea rise as one of the indicators of climate change in the coastal City of Semarang to reach 0.8 mm/year and average soil degradation that ranged between 5 – 12 cm/year cause most coastal communities as well as the social life of the agricultural areas of its economy relies on the resources becoming increasingly erratic.

The capital city of Indonesia, Jakarta, faces chronic flooding which has been and will continue to be exacerbated by climate change processes, including sea level rise and increased rainfall. In response to these threats, the government has devised a megaproject solution to flooding which will simultaneously address the problem while enhancing Jakarta’s status as a ‘world city’, improving the economy of the metropolitan region and the country as a whole. However, the so-called Great Garuda project has a number of major flaws. We describe how this project fails to address the root causes of flooding in Jakarta as well as the primary drivers of vulnerability to flooding. We further show how the Great Garuda project is a channel through which politically connected economic elites of the Suharto regime, now marginalized by democratization and decentralization reforms, can reconstitute ‘growth coalitions’ to benefit from state resources and privileged access to development contracts and concessions. Lastly, we apply and expand on the concept of maladaptation to demonstrate how the project could leave the city and its residents more vulnerable to the impacts of climate change than they currently are.
