In the context of the prevailing environmental crisis, one innovative approach with the potential to promote inclusive conservation is payment for environmental services (PES). While numerous studies have documented the efficacy of PES in terrestrial ecosystems, mechanisms tailored to marine ecosystems remain relatively unexplored. The objective of this article is to conduct a systematic literature review to identify the essential components of a PES mechanism for fisheries and to map the lessons, challenges, and opportunities associated with it. Three databases were explored: Web of Science, ScienceDirect, and Scopus. Using Boolean operators, we searched for articles containing the following terms in the title, abstract, and/or keywords: “payment for ecosystem services” AND “fish*” and “payment for environmental services” AND “fish*”. Twenty-six articles focusing in depth on PES in the context of fisheries were identified. The results indicate that PES is a tool that can reconcile conservation and social objectives while offering numerous benefits for fisheries management. Nevertheless, it is imperative to meticulously evaluate the circumstances under which PES can meaningfully contribute to the inclusive conservation of marine and coastal ecosystems rather than assuming that it is a universal policy panacea.

Anthropized areas in the Brazilian Amazon require detailed mapping to identify zones for sustainable use. This study developed a topoclimatic zoning framework to evaluate the conservation and agroforestry potential of three native species: Carapa guianensis (Andiroba), Dipteryx odorata (Cumaru), and Bertholletia excelsa (Amazon Nut). The hypothesis was that integrating topographic and climatic data can effectively identify high-potential areas for these species to support forest restoration and sustainable management. This study applied ecological modeling and Geographic Information System (GIS) tools to classify zones into high, medium, and low potential for each species. Results showed Carapa guianensis has high potential in 64% of anthropized areas, Dipteryx odorata in 72% of the Legal Amazon, and Bertholletia excelsa in 58%, highlighting their adaptability and strategic value for restoration efforts. The findings emphasize the importance of topoclimatic zoning as a tool for conservation and sustainable use strategies. By aligning with Brazil’s Payment for Environmental Services (PES) Law, this approach can foster agroforestry practices, enhance biodiversity conservation, and strengthen the Amazon bioeconomy, ensuring ecological resilience and sustainable development.

Simple theoretical von Thünenian models of deforestation and agricultural expansion have been extensively studied in the literature but have not yet been adapted to reflect contemporary conservation paradigms, such as the emergence of REDD+ (Reducing Emissions from Deforestation and Forest Degradation) initiatives, related payments for forest conservation, and payments for ecosystem services (PES) more broadly. We revisit Angelsen’s 1999 seminal adaptation of the 1826 von Thünenian model of deforestation and agricultural expansion and propose a “toy model” to incorporate the potential revenues from conservation payments and build on the concept of additionality in the payments for environmental services literature. As theorized, our extended model illustrates how such payments are more effective when they approach the profit margins of geographically peripherical crops that replace the forest. Moreover, it illustrates how conservation payments influence the agricultural frontier while quantifying the avoided deforestation area. Full article

Payments for ecosystem (or environmental) services (PES) encourage land users to manage their land in ways that deliver environmental benefits. This study aimed to assess the water quality in a rural property located in the Protection and Recovery of Watersheds of Campinas, which has been participating in the payment for ecosystem services program since 2018. More specifically, seven points of interest regarding the physicochemical indicators of the water were raised, which were subjected to descriptive statistical and variance analysis. The results revealed significant spatio-temporal variability in the monitored water quality indicators for dissolved oxygen, biochemical oxygen demand, pH, total phosphorus, and total nitrogen. More significant fluctuations were observed in the spatial location of the sampling points for turbidity, temperature, and electrical conductivity. However, the greatest variability depends on the time of year when the samples were collected. Full article

The conservation of biodiversity and forest ecosystems from the perspective of increasingly pronounced climate changes represents a priority objective for present and future society. In recent decades, alongside traditional conservation methods, innovative tools such as PES (Payment for Ecosystem Services) have been introduced to support biodiversity conservation. The aim of this study is to analyze the impact of financial mechanisms for forest ecosystem conservation from the perspective of voluntary adoption by forest owners of additional conservation measures beyond those required by national environmental legislation. Through the conceptual literature review, 6069 articles were analyzed, which described the general context of the application of PES, the aims and objectives related to climate and environmental issues, the beneficiaries, as well as the legislative conditions, and the research direction in the last 7 years. The study aims to provide relevant information regarding the viability and potential impact of PES on achieving the goal of forest ecosystem conservation in Romania, during the period 2017–2023. We identified 904 cases involving 887 entities that have committed to the program for the voluntary adoption of additional measures. It has been stated that a PES approach can lead to increased efficiency in conservation actions. Following the temporal analysis of the number of applications, it was observed that in the first sessions there was a low number of applications, which means very high reluctance of the potential beneficiaries of PES, but once the first program was implemented, their interest increased. The study found a strong correlation between payments and the areas and number of plots under commitment, while there was a less strong correlation with the geographical region. Based on the data obtained, the potential impact of PES in Romania was evaluated at the social level, quantified in the number of applications submitted, and at the economic level, with the amount of money paid to applicants. The environmental impact was measured by analyzing the areas included in the subsidy mechanism and identifying the minimum 20% of the eligible areas, totally exempt from forestry interventions, which produce effects on forests, soil, water and environment.

This study addresses the financial sustainability challenge of integrated watershed management (IWM) in regions with inadequate water service tariffs. A novel water service tariff model is proposed, incorporating supply costs, water loss reduction investments, and IWM expenses informed by user perceptions. The model is applied to an intermediate Andean city in southern Ecuador, where the current tariff impedes the financial viability of the water utility, reflecting a regional trend. The results indicate a necessary tariff increase exceeding 100% to cover the costs and support IWM. The economic value of watershed environmental services (WES) were estimated at USD 1,505,530.64 per year. This value translates to an average water consumption of 20 m³/user/month, equivalent to a WES of USD 2.60 per month. Despite the users’ willingness to pay falling below the estimated economic value of WES, there is a clear need for implementing incentive programs to promote water conservation and policy adjustments that favor the financial sustainability of water supply companies in developing countries.

While protected areas (PAs) are an important conservation strategy to protect vulnerable ecosystems and species, recent analyses question their effectiveness in curbing deforestation and maintaining landscape connectivity. The spatial arrangement of forests inside and outside of PAs may affect ecosystem functioning and wildlife movement. The Osa Peninsula—and Costa Rica in general—are unique conservation case studies due to their high biodiversity, extensive PA network, environmental policies, and payment for ecosystem services (PES) programs. This study explores the relationship between forest management initiatives—specifically PAs, the 1996 Forest Law, and PES—and forest cover and landscape metrics in the Osa Conservation Area (ACOSA). The Google Earth Engine API was used to process Surface Reflectance Tier 1 Landsat 5 Thematic Mapper and Landsat 8 Operational Land Imager data for 1987, 1998, and 2019, years with relatively cloud-free satellite imagery. Land use/land cover (LULC) maps were generated with the pixel-based random forest machine learning algorithm, and Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), and functional landscape metrics were calculated. The LULC maps are the first to track land use change, from 1987 to 2019 and the first to separately classify mature and secondary forest in the region, and have already proven useful for conservation efforts. The results suggest that forest cover, NDVI, EVI, and structural connectivity increased from 1987 to 2019 across the study area, both within and surrounding the PAs, suggesting minimal deforestation encroachment and local leakage. These changes may have contributed to the increasing vertebrate abundance observed in the region. PAs, especially national parks with stricter conservation regulations, displayed the highest forest cover and connectivity. Forest cover increased in properties receiving PES payments. Following the Forest Law’s 1996 deforestation ban, both forest conversion and reforestation rates decreased, suggesting the law curbed deforestation but did not drive reforestation across the region. Connectivity outside of PAs slightly declined following the adoption of the law, so the subsequent forest growth likely occurred in mostly previously unforested areas. Forest expansion alone does not ensure connectivity. We highlight the importance of developing policies, PES programs, and monitoring systems that emphasize conserving and restoring large, connected forest patches for biodiversity conservation and landscape resilience. Resumen: Aunque las áreas protegidas (APs) son una importante estrategia de conservación para proteger ecosistemas y especies vulnerables, algunos análisis recientes cuestionan su eficacia para frenar la deforestación y mantener la conectividad del paisaje. La distribución espacial de los bosques dentro y fuera de las AP puede afectar el funcionamiento de los ecosistemas y los movimientos de la fauna. La Península de Osa–y Costa Rica en general–constituyen casos de estudio únicos de conservación debido a su elevada biodiversidad, su extensa red de AP, sus políticas medioambientales y sus programas de Pago por Servicios Ambientales (PSA). Este estudio explora la relación entre APs, la Ley Forestal de 1996, PSA, cobertura y métricas del paisaje en el Área de Conservación Osa (ACOSA). Se utilizó la plataforma Google Earth Engine API para procesar datos de Reflectancia Superficial Tier 1 Landsat 5 Thematic Mapper y Landsat 8 Operational Land Imager para 1987, 1998 y 2019, años con imágenes satelitales relativamente libres de nubes. Se generaron mapas de uso del suelo con el algoritmo de aprendizaje automático basado en pixeles Random Forest, y se calcularon el índice de vegetación de diferencia normalizada (NDVI), el índice de vegetación mejorado (EVI) y las métricas de paisaje funcionales. Estos mapas, los primeros en clasificar por separado los bosques maduros y secundarios de la región, han demostrado su utilidad para los esfuerzos de conservación. Los resultados sugieren que la cobertura forestal, el NDVI, el EVI y la conectividad estructural aumentaron entre 1987 y 2019 en toda la región de estudio, tanto dentro de las AP como en sus alrededores, lo que sugiere una expansión mínima de la deforestación dentro y fuera de las AP. Estos cambios pueden haber contribuido al aumento de la abundancia de vertebrados observado en la región. Las AP, especialmente los parques nacionales con regulaciones de conservación más estrictas, mostraron la mayor cobertura forestal y conectividad. La cobertura forestal aumentó en aquellas propiedades que recibieron PSA. Tras la prohibición de la deforestación por la Ley Forestal de 1996, disminuyeron tanto las tasas de conversión forestal como las de reforestación, lo que sugiere que la ley frenó la deforestación, pero no impulsó la reforestación. La conectividad fuera de las AP disminuyó ligeramente tras la entrada en vigor de la ley, lo que sugiere que el crecimiento forestal posterior se produjo en zonas que antes no estaban forestadas. Por lo tanto, la expansión forestal por sí sola no garantiza la conectividad. Resaltamos la importancia de desarrollar políticas, programas PSA y sistemas de monitoreo que hagan hincapié en la conservación y restauración de grandes zonas forestales conectadas para apuntalar la conservación de la biodiversidad y la resiliencia del paisaje.

Payment for ecosystem services (PES) is an innovative economic intervention to mitigate the decline of ecosystem services and biodiversity; it plays a key role in harmonizing protection and development. Based on numerous PES practices worldwide, PES has emerged as a research hotspot in the field of sustainability. This paper presents a comprehensive scientometric analysis of PES academic publications between 1987 and 2022. The study aims to characterize the intellectual landscape of PES by identifying and visualizing the evolution of the collaboration network, the co-citation network, and emerging research trends. The findings reveal a rapid increase in publications of this field, indicating its growing importance as an interdisciplinary research subject. In particular, PES has gained significant attention from numerous researchers since 2007. Environmental sciences and ecology (50.77%) have been the core subjects, followed by business economics (11.04%) and biodiversity conservation (9.58%). Engineering (3.52%) and water resources (3.40%) have emerged as new fields in recent years. Notably, productive authors and institutions in this domain are primarily located in the United States, China, and the United Kingdom. However, fewer stable collaborations were found between China and European countries. Regarding the keywords, the most popular keywords of this topic were “ecosystem service” (1423), “conservation” (1324), and “biodiversity” (1029). By synthesizing the literature, this paper identifies pressing topics related to the effectiveness of PES, including the evaluation of effectiveness, efficiency assessment, and equity. Through an in-depth analysis, this paper elucidates global trends and directions in PES research. It is important to create a fair and efficient market that boosts the motivation and initiative of society to engage in PES initiatives, to increase investment in comprehensive PES projects, which helps improve the efficiency of fund utilization, especially concerning climate change mitigation. It is proposed to integrate natural sciences and social sciences to comprehensively assess the effectiveness of climate-friendly PES, which contributes to the sustainable development of PES research and application.

The policy of payments for environmental services is implemented in public policies in Brazil, and there are many efforts to increase projects that subsidize rural producers, combining payments with incentives for good agricultural practices that promote these services. Thinking about ways to add these values in projects to restore degraded areas is an opportunity to generate monetary benefits for producers and attractiveness for stakeholders, aiming to increase investments in projects of this nature and gain scale in the restoration of these areas. In this way, this study evaluated the financial viability of a project to implement 16.9 hectares of agroforestry systems in agrarian reform settlements located in the Descoberto HydrographicBasin near Brasília, Federal District, and the proposition of a scenario of payment for environmental services associated with adoption of this agricultural practice by producers. The results were promising for both investors and farmers, as demonstrated by the financial analysis criteria (NPV: USD 63,097.49, IRR: 71%, simple payback: 3 years). The PES scenario was even more attractive, proving to be an encouraging increase for the adoption of this practice by producers. Full article

The recognition of the natural environment as an element that provides ecosystem services to society has led to an increased interest in the study of these services and the implementation of payment for environmental services (PES) initiatives. Although in recent years it has gained strength as an environmental conservation and restoration strategy, the PES instrument lacks something in the monitoring of its actions that inhibits its concrete efficiency, such as indicators that represent the study area. Based on the results of water, soil, and vegetation quality reported in a case study on a rural property participating in a PES-Water scheme in Brazil, the present study aimed to establish minimum water quality indicators relevant to the monitoring of PES-Water programs and propose a flowchart for monitoring actions and environmental aspects to support future projects of the same nature. Based on the results, the monitoring of these areas must involve the continuous checking of soil indicators, water and vegetation. In addition, details of the microclimate and socioeconomic conditions must be recorded. The results should also be systematized, disseminated, and made available in a monitoring system to serve the various actors involved, thereby facilitating the understanding of the PES instrument and the remuneration for the environmental services provided.

The supply of ecosystem services and the benefits that peri-urban areas provide to society are increasingly being modeled and studied using various ecological, environmental, social, and economic approaches. Nevertheless, the different types and levels of demand, preferences, or values for ecosystem services that different human beneficiaries have, often require information and econometric methods to account for human awareness or knowledge of the spatial underpinnings behind these processes, services, and benefits. Specifically, spatial information regarding the location of an ecosystem, its functions, and its services can play an important role in the value and support for policies affecting conservation of peri-urban ecosystems such as payments for ecosystem service (PES) programs. Such PES programs are policy instruments that promote the use of ecosystem services for resources management and conservation objectives. Therefore, to better address this understudied aspect in the landscape ecology and peri-urban ecosystem services modeling literature, we used an online, interactive, spatially explicit survey (n = 2359) in Bogotá, Colombia to evaluate the role of spatial information on investment and policy preferences for such programs. Using an econometric approach to account for respondents’ spatial literacy (i.e., spatial information) of peri-urban ecosystem services, we analyzed how knowledge of space affected an individual’s choices related to ecosystem services and the economic value of environmental and conservation policies. We found that, as spatial literacy increased, respondents were more likely to prefer that government invest in regulating ecosystem services, specifically water resources, and less likely to prefer investing in other ecosystem services. Although spatial literacy did not necessarily affect respondent’s actual willingness to pay (WTP) for these policies in the form of monthly monetary payments, it did influence the types of programs respondents cared about and the magnitude of resources they were willing to invest. Our findings suggested that increasing spatial literacy would change preferences for government spending but not an individuals’ WTP in contexts such as peri-urban areas and PES programs. Results could be used by landscape ecologists, conservation biologists, natural resource scientists, and environmental/ecological economists to better understand and design more efficient education, conservation, and management strategies to increase public engagement in peri-urban contexts.

The concept of watershed ecological compensation is one payment for ecosystem services (PES) program that incentivizes stakeholders undertake environmental conservation activities that improve the provision of ecosystem services. Defining the heterogeneity of farmers’ willingness to participate in watershed ecological compensation is critically important for fully understanding stakeholders’ demands. Accordingly, we designed a choice experiment survey to analyze the heterogeneity of policy preferences and willingness to receive compensation between upstream and midstream farmers in Xin’an River basin, China. Moreover, we simulated the impact of farmers’ social capitals’ heterogeneity with an agent-based model. The results show that there are significant differences in the preferences of agricultural waste recycling rate and agricultural water quality between farmers in the upstream and midstream. The total willingness of farmers in the upstream and midstream to participate in ecological compensation are RMB 149.88 (USD 22.54)/month and RMB 57.40 yuan (USD 8.63)/month, respectively. Social network size has a negative effect on farmers’ willingness to participate the programs. Our findings suggest that the characteristics of farmers’ influence their willingness to participate in the PES program. The results of this research can be used to improve PES management policies in the future, as well as to support sustainable environmental development and rural revitalization. Full article

Based on the empirical literature of the payments for environmental services (PES) projects for the environmental improvement and poverty reduction, this paper uses a meta-regression analysis method to study whether PES can achieve the effects of improving environmental quality and reducing poverty levels. For the meta-regression analysis, the literature was mainly searched by the Web of Science core journal database. The explanatory variables of meta-regression analysis are the hypothesis and related features of the models in the original literature by generally taking the binary dummy variables or categorical variables. The dependent variables used in this paper are environmental improvement and poverty reduction. The results show that PES projects based on private ownership rights are more conducive to poverty reduction and environmental improvement. If the country is a buyer of a PES project, it is more likely to achieve the effects of environmental enhancement and poverty alleviation. PES projects based on local conditions can also achieve a win–win situation for the two effects. The effects are more effective as policy implementation time is extended. The findings suggest that in developing countries, the government should set different PES projects according to different regions conditions, to promote project implementation through individual voluntary participation, and to achieve the dual purpose of environmental governance and poverty alleviation based on the expectation of long-term implementation of participant projects.

Agricultural land is a very important ecosystem that provides a range of services like food, maintenance of soil structure, and hydrological services with high ecological value to human wellbeing Ecosystem Services (ESs). Understanding the contribution of different agricultural practices to supply ESs would help inform choices about the most beneficial land use management. Nature-based Solutions (NbS) are defined by IUCN (International Union for Conservation of Nature) as actions to protect, sustainably manage and restore natural or modified ecosystems, which address societal challenges (e.g., climate change, food and water security, or natural disasters) effectively and adaptively, while simultaneously providing human wellbeing and biodiversity benefits. Some actions farmers can implement in the new Rural Development Programs (RDP 2021–2022 and 2023–2027) can be considered as NbS and could affect the quantity, quality, and time of some ESs related to water regulation and supply, N adsorption and erosion protection. This study aims to evaluate these ESs in different scenarios in the upper Foglia river basin (Italy) and at a local scale (farming), and to highlight the issue to compensate farmers for the production of public goods which benefit the whole society (ESs) by the implementation of RDP’s actions. These scenarios highlight how actions have positive effects on ecosystem services and their economic value related to land use management, on maintaining agricultural practices by integrating Water Frame Directive (2000/60/EC), Directive 2007/60/EC on the management of flood risks and highlighting the potential role of farmers in a high diversity landscape. This study highlights a new way to evaluate the processes of natural capital in the production of public goods, which benefits the whole society (ESs), by emphasizing the economic and environmental role of farmers in producing them and putting on the table data to trigger a PES (Payment for Ecosystem Services) mechanism. To facilitate decision making, robust decision support tools are needed, underpinned by comprehensive cost-benefit analyses and spatially modeling in which agriculture can be a strategic sector to optimize food production and environmental protection in harmony with the Farm to Fork (F2F) strategy.

Payments for ecosystem/environmental services (PES) have emerged internationally as a new environmental conservation concept over the past two decades. By contrast, Japan has a centuries-long history of using various forms of PES. These schemes can be understood as solutions to interregional problems with forest ecosystem services that have been agreed upon and accepted by the society. This paper aims to consider the significance of PES with respect to cooperative relationships by examining historically formed solutions in Japan. The Japanese experience shows that rather than simply being a demonstration of monetary value, PES in upstream forests were a means of communication across regions, expressing interregional solidarity as a core concept. As connections among communities became less visible, the government artificially created solidarity through payments. The payments gradually shifted from having a socioeconomic meaning to having a psychological meaning. The government sought to substantiate the sense of solidarity by making individual users more aware of the meaning of payments. We can find the significance of this type of PES in the fact that payments can be a way to approach the issue of building solidarity by focusing on the function of payments as messengers rather than them merely having an economic value.
