“…Furthermore, our perception that regional factors may be responsible for cloudiness declines in some TMCF is supported by Los et al (2021), who observed an increase in cloud base height in America's TMCFs over the past four decades, but a decrease in Asia's TMCFs. Helmer et al (2019) predictions, Los et al (2021) findings, and our results support the idea that Neotropical TMCFs are under threat, and thus species and essential ecosystem services that these ecosystems provide (Mayer et al, 2022;Mulligan, 2021).…”

Clouds are critical to the biodiversity and function of Tropical Montane Cloud Forests (TMCF). These ecosystems provide vital services to humanity and are considered hotspots of endemism, given that the number of species is restricted to their microclimates. Cloudiness (e.g., the fraction of low-clouds) in these ecosystems is projected to decline owing to global warming, but recent temporal trends remain unclear. Here, we evaluated trends in low-cloud fractions (CF) and other Essential Climatic Variables (ECV) (e.g., surface temperature, pressure, soil moisture, and precipitation) for 521 sites worldwide with TMFCs from 1997 to 2020. Thus, we hypothesize that recent traces of global warming over the last few decades have led to decreases in low-cloud cover on TMCFs. The previous study was also evaluated globally and among biogeographic realms to identify regional trends. We computed trends by aggregating hourly observations from ERA5 reanalysis and CHIRPS into annual averages and then used linear regressions to calculate slopes (i.e., rate of change) (Δ, year). Our results suggest that CF trends at the TMCFs range between -64.7 ×10 and 51.4 ×10 CF year, revealing that 70% of the assessed sites have experienced reductions in CF. Declines in low-clouds in these ecosystems are 253% more severe than tropical landmasses when peak values of density distribution are compared (TMCFs: -7.8 ×10CF year; tropical landmasses -2.3 ×10 CF year). Despite this, CF trends tend to differ among biogeographic realms, as those TMCFs from the Neotropics and Indomalayan realms have the most pronounced declines. Decreases in CF were also associated with increases in surface temperature and pressure and decreases in soil moisture, revealing that the TMCF’s climate is changing to warmer environments. These climatic shifts may represent a fingerprint of global change on TMCFs, highlighting a current threat to species and essential ecosystem services that these ecosystems provide.

“…Based on the above insights, forest thinning should be a careful action in landscape management. As population pressure and climate stress increase, landscape management will become more difficult, requiring managers to pay more attention to the consequences of forest thinning at the economic, policy, and landscape levels, as well as to the processes of regeneration and ecosystem succession at thinning sites (Mayer et al, 2022; Sharma et al, 2020; C. Wang, Liu, Qiao, et al, 2023; C. Wang, Liu, Wu, et al, 2023). Therefore, China needs a more flexible policy framework that includes a range of adaptive management activities to rationalize forest thinning areas, fully consider the resilience of thinned patches and reduce the risk of declining ecosystem services due to forest thinning.…”

Appropriate forest thinning measures can mitigate the conflicting relationship between past excessive afforestation and current increasing regional water deficiency in dryland ecosystems. However, since blind intervention in forest landscapes may incur additional economic costs and cause the loss of ecosystem services, forest thinning in drylands mostly exists in scientific discussions and is seldom implemented in reality. In this study, we propose an advanced technical route to predict the spatial arrangement of potential forest thinning locations under different policy scenarios. Taking Shanxi Province in China as a case study, we simulated eight policy scenarios for different stakeholders to assess the benefits and costs after forest thinning in the future. The results show that a water deficit of 533 million m3 exists in Shanxi Province that could potentially be mitigated by means of forest thinning. Under different policy scenarios, the thinned area ranged from 1142.91 to 1195.47 km2, which would result in an additional soil loss of 1.77–3.02 million m3/year and a loss of carbon sequestration of 3.15–3.24 million t/year. Considering both soil conservation and food security scenarios can help minimize the direct costs and loss of forest carbon sequestration capacity and maintain a sustainable landscape pattern. The method can be used as a decision support tool to identify the potential locations of forest thinning and resulting consequences under water scarcity conditions in drylands and to support stakeholders in making scientific adaptive forest landscape optimization decisions.

“…Puesto que, los resultados obtenidos pueden ser incorporados al Análisis de Costo Beneficio (Dextre et al, 2022); también, ayudará a integrar los recursos naturales en la planificación del desarrollo a nivel distrital, provincial o nacional, promoviendo la conservación, recuperación y uso sostenible (Hernández et al, 2014). Además, la valoración económica ambiental va permitir proponer a las autoridades provinciales y distritales instrumentos regulatorios ambientales como ordenanzas municipales de conservación, incentivos, Mecanismos de Retribución por Servicios Ecosistémicos (MERESE), acuerdos por conservación, fondos de agua, (MINAM, 2016); establecer multas y sanciones cuando se produce algún tipo de contaminación o impacto (Mayer et al,2022). En consecuencia, los objetivos planteados en la investigación fueron: evaluar la influencia de los factores socioeconómicos y medioambientales en la valoración económica ambiental del recurso hídrico proveniente de la cuenca del río Chirimayo en los distritos de Chadín y Paccha y estimar la disposición a pagar promedio mensual por parte de los usuarios del recurso hídrico de la mencionada cuenca.…”

The economic environmental valuation is a tool that assigns monetary value to ecosystem services, regardless of whether they have market prices or not. The aim of this research was to evaluate the influence of socioeconomic and environmental factors on the economic environmental valuation of water resources from the Chirimayo River basin in the districts of Chadín and Paccha (Cajamarca - Peru), and to estimate the average monthly willingness to pay by users. The contingent valuation method and Logit econometric model were used, with questionnaires and interviews administered to 285 users out of a population of 1104. Results show that the majority of users are between 46 and 60 years old, male, married, with 4 family members, primary education, farmers, with incomes between 200 and 500 soles; they use the water resource for human consumption, which is of good quality, available 24 hours a day, although the volume has decreased, and they are willing to pay for it. It is concluded that economic valuation is positively influenced by gender, level of education, and hours of service; thus, an increase in one unit of these factors leads to a greater willingness to pay. However, age and marital status have a negative influence, as an increase in age decreases the willingness to pay, and singles show less willingness. On average, 75.8% of the population is willing to pay 1.60 soles per month.
