Abstract. Aboveground biomass estimation (AGB) is essential in determining the environmental and economic values of mangrove forests. Biomass prediction models can be developed through integration remote sensing, field data statistical models. This study aims to assess compare predictor potential multispectral bands, vegetation indices biophysical variables that derived from three optical satellite systems: Sentinel-2 with 10 m, 20 m 60 resolution; RapidEye 5m resolution PlanetScope 3m...

Abstract. Many studies have been conducted in the estimation of forest above ground biomass (AGB) using features from synthetic aperture radar (SAR). Specifically, L-band ALOS/PALSAR (wavelength ~23 cm) data is often used. However, few made on use shorter wavelengths (e.g., C-band, 3.75 cm to 7.5 for mapping especially tropical forests since higher attenuation observed volumetric objects where energy propagated absorbed. This study aims model AGB estimates mangrove information derived...

Ecosystem services (ES) are benefits nature provides to humans; these change in space and time largely dependent on context. Coastal habitat that key ES blue carbon ecosystems, namely seagrass mangroves. One important they provide is the provisioning of seafood, which coastal populations with livelihoods food security. We employed a social-ecological approach draws from vulnerability literature for social, ecological, economic criteria map provision ten communities Busuanga Island, Palawan...

Abstract Drag effects of mangrove forests with complex root systems modulate flow and substance transport promote sedimentation, all which are linked to mangroves' ecosystem services (e.g., coastal protection, trapping suspended organic carbon) resilience vertical accretion relative sea‐level rise). Previous flume studies proposed a predictive model drag by Rhizophora based on the quadratic law using two parameters‐drag coefficient ( C D ) vegetation projected area density ). However, its...

Abstract. Mangroves have been protecting coastlines, nourishing wildlife, and capturing carbon for climate regulation. The decline of mangroves calls action to rapidly accurately monitor them. Remote Sensing makes it possible remotely from images captured space. Sentinel-1 Sentinel-2 are examples remote sensing satellites there is extensive research on their land cover mapping capabilities, including mangrove mapping. While machine learning a popular methodology (e.g., the use Random Forest)...

Abstract. Urbanization has played an important part in the development of society, yet it is accompanied by environmental concerns including increase local temperature compared to its immediate surroundings. The latter known as Urban Heat Islands (UHI). This research aims model UHI Quezon City based on Land Surface Temperature (LST) estimated from Landsat 8 data. Geospatial processing and analyses were performed using Google Earth Engine, ArcGIS, GeoDa, SAGA GIS. Based Thermal Field Variance...

Abstract. Urbanization can be observed through the occurrence of land-use changes as more land is being transformed and developed for urban use. One Philippine cities with high rate urbanization Baguio City, known having a subtropical highland climate. To understand spatiotemporal relationship between temperature, this study aims to analyze correlation extent surface air temperature in City using satellite-based built-up extents, (LST) maps, weather station-recorded data. Built-up layers...

Moderate to high resolution satellite imageries are commonly used in mapping mangrove cover from local global scales. In addition extent information, studies such as composition, ecology, and distribution analysis require further information on zonation. Mangrove zonation refers unique sections within a forest being dominated by similar family, genus, or species. This can be observed both natural planted forests. this study, workflow was developed detect test sites Katunggan-It Ibajay (KII)...

Abstract. The Mangrove Vegetation Index (MVI) was developed to map mangroves extent from remotely-sensed imageries accurately and quickly. MVI measures the probability of a pixel be ‘mangrove’ by extracting greenness moisture information green, NIR, SWIR bands. range values may vary depending on factors such as land cover classes, climatic conditions, or tidal conditions. Mapping scope mangrove sites involves setting maximum minimum threshold separate them other classes vegetation. Although...

Phytoplankton were collected from eight sampling stations around Lake Buhi (Camarines Sur, Philippines) in September and November 2013. The sites represented varied zonation resource uses. A total of 29 species identified belonging to five major taxonomic groups: the diatoms (Heterokontophyta), green algae (Chlorophyta), cyanobacteria (Cyanophyta), eustigmatophytes (Heterokontophyta) dinoflagellates (Dinophyta). Diatoms were most abundant group (50%), followed by (41%). Sampling station...

Abstract. The Philippines has a booming sugarcane industry contributing about PHP 70 billion annually to the local economy through raw sugar, molasses and bioethanol production (SRA, 2012). Sugarcane planters adapt different farm practices in cultivating sugarcane, one of which is cane burning eliminate unwanted plant material facilitate easier harvest. Information on burned extent significant yield estimation models calculate total sugar lost during Pre-harvest can lessen sucrose by 2.7% -...

Abstract. This study produced spatiotemporal hot and cold spot occurrence maps for Davao City the period 1994-2019 using land surface temperature (LST) images. Urban heat is theorized to have been affected by some, if not all, of following impact factors: air pollutant concentrations/particulate matter (PM10), vegetation “abundance” (using EVI), building “density” (NDBI), albedo, topography, population density. A mobile traverse sampling was performed in morning afternoon 15 April 2019...

Abstract. Mangroves are considered one of the most undervalued ecosystems in world. It provides shelter to a wide range species and protection from natural hazards coastal communities. The Philippines, being country with long coastlines, benefits greatly mangroves. Historically, it had 400,000–500,000 hectares mangroves forest 1920, which declined 120,000 1994 due rapid industrialization, particularly conversion these forests into aquaculture such as fishponds Mangrove Philippines saw...

Abstract. Mangroves are important vegetation that provides coastal protection and basic life necessities to humans different marine organisms. Studies have observed mangrove deforestation is occurring in the Philippines. Thus, monitoring of extent fragmentation for rehabilitation planning necessary prevent further cover loss. The utilization free satellite imagery helps this enterprise as it reduces need expensive field activities. Furthermore, allows researchers perform spatio-temporal...
