River floods frequently occur when tropical cyclones hit land. Nonetheless, systematic, long-term discharge data remain rather scarce in many countries, which prevent proper analysis of peak discharges occurring during floods. The Térraba catchment is the biggest and most dynamic Costa Rica. In this study, we developed regional flood-frequency analyses combining tree-ring based estimation measurement at monitoring stations to derive flood quartiles. Flood quartiles were combined with Topographic Wetness Index (TWI) determine hazards along floodplains. risk assessment was on a high-resolution mapping infrastructure, population density (as measure exposure), social development index (to represent vulnerability). We show that cyclone-induced can be assessed accurately including dendrogeomorphic reconstructions systematic measurements. also assessments performed large-scale catchments if both coarse detailed inputs are used. results study will useful for schemes promoting resilience local populations.

Over the last decades, Costa Rica became established as a world-leading ecotourism destination due to its environmental policies and awareness. The country is located in dynamic region where combination of tectonics volcanism, tropical climate vegetation have molded landscapes. Our aim carry out review geodiversity, geoconservation, geotourism status Rica. We analyzed different geomorphic environments (volcanic, coastal, karstic, glacial, fluvial), prospecting importance Conservation Areas National System for promotion national geoheritage through geotourism. results are critical geosciences wider public throughout conservation decision-makers. In dynamic, geomorphic, tropical, developing countries with strong anthropic pressures over their geo- biodiversity, studies might be priority increasing revenues reducing pressure on natural resources.

Central America is located in a dynamic region where tectonics and volcanism together with the tropical climate its diverse vegetation have shaped landscapes. Our main objective to review status of geodiversity, geoconservation, geotourism America. We will identify region’s geomorphic environments geodiversity using classic regional geomorphology mapping techniques. Likewise, touristic maps webpages, we most prominent geosites different origin Moreover, explore national environmental policies, natural conservation systems, tourism initiatives promote their geoheritage through geotourism. found that volcanic, coastal, karstic, glacial, fluvial are common region. In addition, identified 393 fluvial, archeological The promotion geoheritage, thus development geoparks excellent opportunities sustainable development, lifestyles, appreciation cultural diversity, peace. These results may prove important spread information about geoscience widely decision makers on each country stakeholders Geoheritage studies developing countries such as those should be improved, priority given geomorphological dynamics strong anthropic pressures geo- biodiversity increase income geotourism, especially among less favored communities avoid affecting already threatened resources.

High mountain areas are critical for water security and natural hazard dynamics, as well glacier ecosystem conservation in a warming world. We present brief account of the methodological steps geomorphological mapping areas, including required scale, legends, technology, software. analyze best imagery sources their combination with fieldwork geographical information systems (GIS), performing accurate cartography. In addition, we two case studies which apply several methods described previously. Firstly, carried out classical digital Cerro Chirripó (Talamanca Range). Secondly, studied Reserva Biológica Alberto Manuel Brenes (Central Volcanic Range), where used UAVs to map high-resolution fluvial geomorphology. This framework is suitable future surveys worldwide. Moreover, can give ideas on application these approaches different mountainous environments.

Abstract Páramos, a neotropical alpine grassland‐peatland biome of the northern Andes and Central America, play an essential role in regional global cycles water, carbon, nutrients. They act as water towers, delivering ecosystem services from high mountains down to Pacific, Caribbean, Amazon regions. Páramos are also widely recognized biodiversity climate change hot spots, yet they threatened by anthropogenic activities environmental changes. Despite their importance for security carbon storage, vulnerability human activities, only three decades ago, páramos were severely understudied. Increasing awareness need hydrological evidence guide sustainable management prompted action generating data filling long‐standing knowledge gaps. This has led remarkably successful increase scientific knowledge, induced strong interaction between scientific, policy, (local) communities. A combination well‐established innovative approaches been applied collection, processing, analysis. In this review, we provide short overview historical development research state hydrometeorology, flux dynamics, impacts, influence extreme events páramos. We then present emerging technologies hydrology resources discuss how converging science policy efforts have leveraged traditional new observational techniques generate base that can support conclude co‐evolution was able successfully cover different spatial temporal scales. Lastly, outline future directions showcase long‐term collection foster responsible conservation towers.

Despite of the geomorphological diversity Central America and Costa Rica, there are few detailed studies in region. A 1:25,000 analyses Upper General River Basin (UGRB) located southeast Rica is presented, based on interpretation aerial photographs field mapping. First, a morphometric analysis was performed to calculate analyze seven variables that were merged order produce flood landslides susceptibility maps. Second, total 43 types landforms divided genetically into endogenic (tectonic), exogenic (fluvial, gravitational, glacial) features mapped for an area 1560 km2. Finally, hazard map with zonation different levels floods performed. This cartography important terms evolution, disaster risk reduction as well land use planning approximately 40,000 inhabitants. The presented methodology can also be applied other developing countries purposes such landscape morphogenetic maps, reduction, planning.

Numerous high elevation tropical mountains around the world show evidence of past glacial activity during Last Glacial Maximum (LGM). Cerro Chirripó in Costa Rica exhibits paleoglacial landforms such as cirques, moraine deposits and polished striated bedrock surfaces. We used aerial imagery (1:25000) contour lines to develop a Digital Elevation Model (DEM) for LGM. determined paleo-equilibrium line altitudes (paleo-ELAs) using Area-Altitude Balance Ratio (AABR) LGM Rica. Additionally, Generalized Linear (GLM) was performed statistically analyze paleoglacier volumes ice thickness combined with ten land surface parameters (LSP). Our results identified thirty-one paleoglaciers covering an area 28.26 km2 global LGM, maximum 178 meters Chirripó, total volume 13863 × 105 m3 mean paleo-ELA 3490 meters. In addition, Area Slope were LSP highest statistical correlation explain volumes, while Diurnal Anisotropic Heating best thickness. As one first studies mountain environments, this work expands geographic scope glacier reconstructions expansion
