Abstract

The research about the identification of mangrove physical condition and the change of mangrove area has aims are knowing of mangrove physical condition and the change of mangrove area in the coastal region southern part of Padang city. The method used in this research is the field survey and multi-temporal satellite imagery analysis in 2001 and 2018 year. Based on the field survey at the date of August 18, 2017 generally the mangrove that found in research location i.e Rhizophora Apiculata, Rhizophora mucronata, Sonneratia alba, and Nypa. The spatial distribution of the mangrove ecosystem is dependent on the ecological conditions of the area as reflected by the types of mangrove vegetation that grows and develops in the research location. A decrease in mangrove area that occurred between of 2001 to the 2017 years i.e in the coastal region of Bungus bay i.e 5.54 ha, where the decrease in mangrove area occurred because some mangrove plants were cut down and made the settlement land, while in the region of Sungai Pisang bay happen to increase in mangrove area i.e 36.12 ha, where the increase in mangrove area occurred because of the region obstructed by big waves of the sea (protected small the islands).

Abstract

The most fundamental problem in this research is land cover change into settlement area and open land that occurred are high in Padang City, so the forest has reduced. If cover land of forest reduced, while population, industry and transportation growth increase the environmental gap due to plants absorbing emissions released by human activity is reduced. As a result the surface temperature becomes warmer. If this is left continuously, the hydrometeorology disaster will threaten Padang City. In general, this research aims to determine how the phenomenon of climate change that occurred in Padang City based on the estimation of carbon stocks in accordance with land cover. Analysis of the occurrence of climate change can be known based on the tendency of temperature data and rainfall data contained in Padang City. In addition, climate change can be analyzed based on changes in land cover and carbon stocks. Based on the result, it is known that Padang City since 1989 experienced considerable changes, especially changes from forest to settlements and mixed land. That land cover changes, indirectly cause the carbon stocks of Padang City also decreased. This is because other land cover rather than forests have low carbon stocks, especially settlements and open land that do not have carbon stock. Carbon stocks reduced, it is assumed to cause increasing air temperature and reducing rainfall.

Abstract

Adaptation of the community to flood natural disasters is part of the flood mitigation natural disaster that often occurs in the rainy season. The aims of this research is to analyze landform units and land characteristics that have flood hazards and community adaptation strategies in dealing with flood natural disasters. The method used in this research is the survey method, which is to collect data on land characteristics as characteristics or characteristics of flooded areas and interviews with local communities about adaptation strategies undertaken to deal with flood natural disasters. The results showed that the landform units formed due to the flood process in the study area were in the form of floodplains, back swamps, alluvial terraces, depression inter beach ridge, and alluvial plain complexes. The unit characteristics of landforms generally have flat morphometry with slopes ranging from 0 - 2%, the genesis of these landform units due to fluvial and marin processes. The constituent material in this area is mud to coarse sand. The rock conditions in this area are rocks originating from volcanoes and undergoing a process of destruction due to processes from the river so that the rocks in this area are gravel, rough sand, fine sand. Soil conditions in each unit of landform also vary from the formation of soil to on newly developed land. Vegetation that grows in each unit landform of this is in the form of natural vegetation and lovely water vegetation or vegetation which requires a lot of water for its growth and development. The community strategy in dealing with flood natural disasters is in the form of staging houses, knowing the time of occurrence of tides, and opening the river estuary if the river estuary is covered by sediment.
