“…The northern slope of Cerro Anguciana (Fig. 2c) seems more deforested as compared to the southern slope (our observations in 2003, Pérez-Rubio & Mende 2018, possibly because of a lower steepness for logger trucks on the former. In view of this, the national park of Piedras Blancas created in September 1991 could be expanded to the northeast to include the southern slope of Cerro Anguciana.…”

A new wild bean found in the mountainous range “Fila Cruces” of southeastern Costa Rica is described. To date, only four populations are known from different sites on the slopes of Cerro Anguciana and “Fila Cruces” where it seems to be endemic. The differences (slender curved racemes, small oval acuminate primary and pedicelar bracts, lilac inner face of standard, white wings) are presented with closely related species such as P. hygrophilus and P. oligospermus of the section Brevilegumeni to which it may belong.

“…Spatial statistical analyses, such as the Moran Index, have been used to evaluate the distribution of physical phenomena such as soil erosion [26], rainfall [27], and ecological features [28], generating clustered results similar to those of this study. On the other hand, this process has mostly been applied in human and social studies, in order to evaluate distribution, segregation, and transformations, among other social phenomena [29,30], while other studies have focused on distribution phenomena or spatial autocorrelation theory [31][32][33].…”

Regional Patterns of Coastal Erosion and Sedimentation Derived from Spatial Autocorrelation Analysis: Pacific and Colombian Caribbean

Coastal erosion is a common phenomenon along the world’s coasts. Studying it is complex because such studies must cover large portions of land, and it is necessary to understand the multiple processes that interact in each area, so it is important to recognize regional patterns that allow for defining representativeness in relation to the surrounding dynamics. Spatial statistics can be used in coastal geomorphology to identify and quantify trends in coastal morphodynamics. This study analyzes and interprets the spatio-temporal patterns present in the changes in a shoreline, that is, the processes of erosion and coastal sedimentation in the Pacific and the Colombian Caribbean. The results are derived from the detection of significant changes in the coastline via satellite images. For this study, the shoreline of Colombia was digitized for the years 1986 and 2016, thus obtaining changes in the shoreline at a medium temporal scale. The Global Moran’s Index, Local Moran’s Index and Getis–Ord Index were used to explain the spatial statistics. The Global I Moran values for the Pacific were I = 0.190, z = 31.063 and p = 0.01, and for the Caribbean I = 0.624, z = 74.545 and p = 0.01, which suggests good grouping in the Caribbean and very low grouping for the Pacific. The local indices (Moran’s and Getis–Ord) allowed us to visualize and spatialize the significant points of coastal erosion and sedimentation. According to the results, three conceptual models are herein proposed that relate the indices with the geomorphological characteristics: (a) the greater the geomorphological heterogeneity, the greater the grouping; (b) the greater the geomorphological homogeneity, the lower the degree of clustering; (c) the greater the geomorphological complexity, the lower the degree of clustering. Finally, it is confirmed that coastal erosion and sedimentation processes predominate along low coasts.

“…Empirical results suggest a strong spatial correlation between the erosion susceptibility index and land use and land cover data. The highest index values were reached in pasturelands and disturbed forests, and the lowest values in natural forest areas [80,81]. As part of an integrated assessment approach, employing primary data, an erosion susceptibility map was generated by using artificial neural networks [80].…”

“…The first research question of this study was how to assess the extent to which cattle ranching landholders located in the Claro River sub-watershed would be willing to implement restoration projects within their properties through a hypothetical PES scheme. This question was raised based on the results obtained from primary data through a GIS-based spatial assessment, which demonstrated the presence of high levels of erosion susceptibility in the upper sub-watershed and a strong spatial correlation with cattle rangelands [80,81]. The selection of the erosion control (ERO) attribute along with two other ESs (water availability and biodiversity) in the CE model allowed us to elicit the respondents' preferences for them in order.…”

Deforestation and the unsustainable management of agricultural and livestock production systems in tropical mountain areas have caused fragmented and degraded landscapes. Payment for ecosystem services (PES) could be an effective policy instrument with which to reduce deforestation and restore disturbed ecosystems. The national-scale PES program in Costa Rica is recognized as being successful; however, its financial resources have been mostly dedicated to forest protection, and much less to reforestation projects. This paper aims to construct a micro-scale PES scheme by using primary data generated through spatial modeling and socio-economic and stated preference surveys (choice experiment) in southern Costa Rica. The results suggest that, on average, landholders would agree to implement restoration projects on their own private pasturelands if an appropriate holistic place-based approach was applied encompassing biophysical, social, economic, and institutional aspects. Willingness-to-accept values allow payments to be linked to cattle farmers’ estimates of specific ecosystem services (ES) and land opportunity costs. The economic valuation of three ESs (erosion control, water availability, and biodiversity) allows construction of a layered payment scheme, which could encourage the development of a potential partnership between national and local institutions and NGOs as alternative buyers of ESs, reduce transaction costs, and improve household well-being.
