The most fundamental problem in this study is the high change of land cover that occurred in the city of Padang into settlements and open land, so that forest cover becomes reduced. If forest cover diminishes, while population, industry and transportation growth is increasing, environmental inequalities from plants absorbing emissions released by human activity decrease, so the surface temperature becomes warmer. If this is allowed to continue, then the hydrometeorological disaster will threaten the city of Padang. In general, this study aims to determine how the phenomenon of climate change that occurred in the city of Padang based on the estimation of carbon stocks in accordance with land cover. This research uses a combination of remote sensing technology with direct measurement in the field. The integration of land cover change data with the value of carbon stocks on a plot scale can illustrate changes in carbon stocks on a landscape scale. The results show that within 1989-2017 there has been a change in forest cover to non-forest land that leads to a decrease in carbon stocks and increased carbon emissions. Increased carbon emissions in the atmosphere caused a change in rainfall in Padang City, where Padang City had a high rainfall ranging from 4500-6000mm / year, while now decreasing to 3000-4500 mm/year indicating that climate change has occurred in Padang City.

that are converted into built-up lands such as housing, shops and industry. According to Darmawan (2002), one of the factors that cause land change is the socioeconomic factors of the community related to the needs of human life. One of the provinces that experienced the largest paddy land conversion in Indonesia is the West Sumatra region. Many factors result in land use changes that have an impact on the land itself, such as social, and economic factors and also factors of increasing the number of inhabitants. Land use change is the transition of an old form and location of land use to a new one. Or the change in the function of agricultural land such as built-up land (Adhiatma et al., 2020). The selection of the Padang City Area as a research site was based on significant land use changes in Padang City, this was caused by several factors such as the rate of population growth in Padang City which increased every year based on BPS data in 2015-2020 period was 1.52% with a population of 909.04 thousand people in 2020. The spatial pattern that has been set by the government in general in the city of Padang is an area developed for the cultivation of rice fields covering an area of 4540.10 ha. Based on BPS data from Padang City, the area of paddy fields decreases by 0.7% every year which is converted into housing and shops and industries in Padang City. The development of built-up land that occurred in the city of Padang slowly changed the rice field area into a built-up area that was not by the provisions of the spatial pattern that had been set by the local government. The spatial pattern that has been set by the government so that the area of paddy fields can be maintained by utilizing remote sensing data. By using remote sensing data such as imagery. Spot imagery is one of the high-resolution remote sensing images that is a French-owned satellite that operates to provide remote sensing data. SPOT imagery provides an imaging instrument that is then carried out as an overlay method between the rice field map and the rice field space pattern that has been set by the government to see its suitability. High-resolution optics are synonymous with panchromatic (P) and Multispectral (Green, Red, and Near Infrared). SPOT imagery has a spatial resolution of 2.5meter 10meters with a wide viewing angle that covers 60 x 60 km or 60 x 120 km in twin mode instruments, and an orbital altitude of 822 km, SPOT provides an ideal combination of high resolution and also wide visibility that can meet the needs of data that is accurate enough for identification of rice fields.

The Mandeh regions is one of the coastal and marine ecosystems in the Province of WestSumetera. Mandeh regions has mangrove forests, seagrass beds and sizable coral reefs. Nowadays, Mandehregions has been completed in the development, especially in development of road access to increase theacceleration of the development of Mandeh tourist destinations as a new destination in West Sumatra.However, in that development, it turns out that it has affected many forest ecosystems and coastal and marineecosystems, one of which is the reduction of blue carbon which is one of the ways to mitigate climate change.Therefore, this research is very important to do considering the impact of development on the coastal andmarine ecosystems. This research is the first study conducted in the Mandeh regions with a focus on estimatingblue carbon stored in mangrove forests and coral reefs. This study aims to determine and analyze the bluecarbon contained in the Mandeh regions after the development, especially the opening of roads. The resultsshowed that from 1999 to 2019 there was an ecosystems degradation which caused a decrease in carbon stocks.Estimated carbon stock in the mangrove ecosystem is around 257 Mg.C / Ha and coral reefs 3291 g.C / m2.Estimated carbon stock is not much different from other studies in Indonesia, thus after the opening of the roadin Mandeh regions does not significantly affect mangrove ecosystems and coral reefs, so that ocean carbonuptake, is still quite large.
