A Systematic Review Of Blue Carbon Potential in Coastal Marshlands: Opportunities For Climate Change Mitigation And Ecosystem Resilience

This systematic review evaluates the blue carbon potential of coastal marshlands, emphasizing their role in climate change mitigation, ecosystem service provision, and economic value within climate finance mechanisms. Drawing on a comprehensive analysis of 198 peer-reviewed articles, this study synthesizes findings on the carbon sequestration dynamics of coastal marshlands, their contributions to biodiversity support, and their capacity to enhance coastal resilience through flood protection and water quality improvement. The review highlights the threats posed by land-use changes, urbanization, and climate change impacts such as sea-level rise and saltwater intrusion, which collectively undermine the ecological integrity and service delivery of these critical ecosystems. It further explores the integration of coastal marshlands into climate finance mechanisms, demonstrating their viability as natural assets within carbon markets and payment for ecosystem services schemes, with restoration projects yielding returns of $7 to $15 for every dollar invested. Despite these advancements, significant knowledge gaps remain, particularly in the standardization of methodologies for quantifying carbon dynamics and the socio-economic benefits of conservation, which limit the scalability of these efforts. By addressing these challenges, this study underscores the necessity of interdisciplinary approaches, robust policy frameworks, and sustained research to maximize the potential of coastal marshlands as a cornerstone of nature-based solutions for climate mitigation and sustainable development.

Assessing the Impacts of Nature-Based Solutions on Ecosystem Services: A Water-Energy-Food-Ecosystems Nexus Approach in the Nima River Sub-Basin (Colombia)

Forest ecosystem services are critical for maintaining ecological balance and supporting human well-being from different perspectives. However, rapid land use changes driven by agricultural expansion, urbanization, and industrial activities have significantly altered forest ecosystems, degrading the services they provide. We here conduct an ecosystem service assessment through biophysical and economic estimates for a multipurpose Andean water sub-basin in western Colombia. We compare a business as usual (BAU) with a forest nature-based solution (NbS) scenario focused on forest landscape restoration. The research employed participatory methods for the NbS selection and economic valuation techniques to evaluate water flow regulation, water provisioning, water purification, and food provisioning services. Results show that the NbS scenario yielded a net positive economic impact across most evaluated ecosystem services, with notable trade-offs. Specifically, the NbS scenario increased water retention by 2.9% compared to BAU. Water flow regulation demonstrated the most substantial economic benefit, increasing by EUR 11.39 million/year in the NbS scenario. On the other hand, the food provisioning service presented a reduction of EUR 3.2 million/year in the NbS scenario. These findings highlight the potential of forest-based NbS to address the Water–Energy–Food–Ecosystem (WEFE) nexus challenges. The study’s outcomes provide valuable insights for policymakers and practitioners, supporting the development of Payment for Ecosystem Services schemes and integrating ecosystem service valuation into land use planning and decision-making processes.

The need for carbon finance schemes to tackle overexploitation of tropical forest wildlife.

Defaunation of tropical forests, particularly from unsustainable hunting, has diminished populations of key seed dispersers for many tree species, driving shifts in forest community composition toward small-fruited or wind-dispersed trees with low wood density. Such shifts can reduce aboveground biomass, prompting calls for overexploitation to be included in bioeconomic policy, but a synthesis of existing literature for wildlife impacts on carbon stores is lacking. We evaluated the role of wildlife in tropical forest tree recruitment and found that it was critical to tropical forest carbon dynamics. The emerging financial value of ecosystem services provided by tropical forest fauna highlights the need for carbon-based payments for ecosystem services schemes to include wildlife protection. We argue for three cost-effective actions within carbon finance schemes that can facilitate wildlife protection: support land security opportunities for Indigenous peoples and local communities; provide support for local people to protect forest fauna from overexploitation; and focus on natural regeneration in restoration projects. Incorporating defaunation in carbon-financing schemes more broadly requires an increased duration of carbon projects and an improved understanding of defaunation impacts on carbon stores and ecosystem-level models. Without urgent action to halt wildlife losses and prevent empty forest syndrome, the crucial role of tropical forests in tackling climate change may be in jeopardy.

A Systematic Review of Empirical Research on Payment of Ecosystem Services and Farm Household Income in China

The payment for ecosystem services (PES) scheme shows great poverty alleviation potential and recognizing this connection contributes to enhancing the development of residents in ecologically endowed areas. However, the literature has not clarified the extent of the promotion and moderating factors of PES on income yet. This study pursues the goal of identifying the effect of PES on household income in rural China from the income structure perspective. Methodologically, this research conducts a literature review of 28 papers to outline the effect of PES on agricultural production, off-farm, and total income, and it applies a meta-analysis and meta-regression analysis of 13 papers to identify the influencing degree and interference factors. The findings reveal four issues. Overall, the effect of PES on agricultural production income was negative, while the effect on off-farm and total income was positive. Second, the PES schemes boosted farm household income by 0.15 weighted average effect size. Third, farm household participation area, subsidized unit prices, and urbanization level played positive moderating effects, while farm household age was a negative moderating variable. Lastly, PES risk exacerbated income inequality among farm households. The study also integrates the PES and the SDGs, proposing that advancing climate action involves the assistance of sustainable communities, decent work, and protection from conflict with social equity. Finally, the paper provides recommendations in terms of government-led PES projects that should be inclusive of economic, social, and ecological objectives, provide job security for smallholders, and quality urbanization.

Public Willingness to Pay for Farmland Eco-Compensation and Allocation to Farmers: An Empirical Study from Northeast China

Farmland eco-compensation, as a typical payment for ecosystem services scheme, aims to address trade-offs between environmental and developmental objectives. As indispensable eco-compensation supporters, the public’s willingness to pay (WTP) for farmland eco-compensation and the allocation to farmers directly affect ecological safety and sustainable development for farmland. Therefore, this study links the public’s WTP for the farmland eco-compensation to the financial subsidies received by farmers and presents a theoretical framework and research approach that connects stakeholders, applying improved choice experiments for empirical study in the black soil region of northeastern China. The results showed that the public has a positive WTP for the farmland eco-compensation program that improves the area, soil thickness, and organic content expeditiously. The public’s WTP allocation for eco-compensation varies considerably, with the share allocated to farmers in their WTP averaging 46.96%, showing a benchmark for compensation standards. The results revealed the influential relationship between the socioeconomic characteristics of the public with WTP allocation and the preferences for farmland eco-compensation, such as the positive correlation between age with WTP allocation and females’ greater preference for eco-compensation. These findings can provide new perspectives and approaches to exploring sustainable pathways for farmland eco-compensation.

Impact of Deforestation on Water Quality in Cameroon

Purpose: The aim of the study was to analyze the impact of deforestation on water quality in Cameroon. Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries. Findings: Deforestation in Cameroon significantly impacts water quality, as evidenced by increased sedimentation, higher pollutant levels, and elevated risks of waterborne diseases. Loss of forest cover reduces natural filtration capacities, leading to higher concentrations of contaminants in water sources. Alterations in hydrological patterns and changes in land use further exacerbate these issues, affecting water availability and aquatic habitats. Unique Contribution to Theory, Practice and Policy: Hydrological cycle theory, land use/land cover change (LU/LC) theory & ecosystem services theory may be used to anchor future studies on impact of deforestation on water quality in Cameroon. Implement land-use planning measures that prioritize the conservation and sustainable management of forest ecosystems, including protected area designation, forest restoration initiatives, and sustainable forest management practices. Develop and enforce policies that incentivize forest conservation and sustainable land management practices, such as payment for ecosystem services schemes, land-use zoning regulations, and carbon offset programs.

Exploring local perceptions and drivers of engagement in biodiversity monitoring among participants in payments for ecosystem services schemes in southeastern Mexico.

Payments for ecosystem services (PES) are widely applied incentive-based instruments with diverse objectives that increasingly include biodiversity conservation. Yet, there is a gap in understanding of how to best assess and monitor programs' biodiversity outcomes. We examined perceptions and drivers of engagement related to biodiversity monitoring through surveys among current PES participants in 7 communities in Mexico's Selva Lacandona. We conducted workshops among survey participants that included training and field deployment of tools used to monitor biodiversity and land cover, including visual transects, camera traps, acoustic recorders, and forest cover satellite images. We conducted pre- and postworkshop surveys in each community to evaluate changes in respondents' perceptions following exposure to biodiversity monitoring training and related field activities. We also reviewed existing research on participatory environmental management and monitoring approaches. One quarter of current PES participants in the study area participated in our surveys and workshops. The majority stated interest in engaging in diverse activities related to the procedural aspects of biodiversity monitoring (e.g., planning, field data collection, results dissemination) and acknowledged multiple benefits of introducing biodiversity monitoring into PES (e.g., knowledge and capacity building, improved natural resource management, and greater support for conservation). Household economic reliance on PES was positively associated with willingness to engage in monitoring. Technical expertise, time, and monetary constraints were deterrents. Respondents were most interested in monitoring mammals, birds, and plants and using visual transects, camera traps, and forest cover satellite images. Exposure to monitoring enhanced subsequent interest in monitoring by providing respondents with new insights from their communities related to deforestation and species' abundance and diversity. Respondents identified key strengths and weaknesses of applying different monitoring tools, which suggests that deploying multiple tools simultaneously can increase local engagement and produce complementary findings and data. Overall, our findings support the relevance and usefulness of incorporating participatory biodiversity monitoring into PES.

Exploring Landscape Values and Willingness to Pay for Perceived Ecosystem Services: The Case of Malampaya Sound, a Socio-Ecological Production Landscape and Seascape

Since the 1990s, the Philippines has established numerous protected areas aimed at preserving regions with distinct biological and ecological characteristics. However, transitioning towards a more comprehensive approach to managing these protected areas, one that effectively conserves biodiversity while also supporting the welfare of local communities, remains a formidable task. Understanding the sources of the goods and services upon which communities rely, whether directly or indirectly, and their perceptions of ecosystem services (ESs) is a crucial aspect that can inform decision-making for both protected area managers and policymakers. This research specifically examines the mapping of landscape values as perceived by local communities within Malampaya Sound Protected Landscape and Seascape (MSPLS) in the Philippines. Using survey questionnaires administered to 114 randomly selected participants, the study identifies the ESs within MSPLS and maps the associated landscape values. The respondents were tasked with assigning values to the ESs using a typology of 14 landscape values, and their willingness to pay (WTP) to enhance the ESs within MSPLS was also investigated. Analysis of socio-demographic data, the identified ESs, and the perceived landscape values was conducted to uncover significant relationships between the variables. Our findings reveal that the respondents prioritize provisioning services, particularly fisheries, agriculture, and agroforestry. Regarding landscape value preferences, economic value is most prominently perceived (37.4%), followed by subsistence value (30.8%) and life-sustaining value (6.8%). This study further unveils the socio-economic factors influencing the ranking of ESs and trends in WTP for ES improvements in Malampaya. Additionally, a potential payment for ecosystem services scheme in MSPLS is estimated at PHP 532,000, approximately USD 10,600.

On the palm oil-biodiversity trade-off: Environmental performance of smallholder producers

Oil palm remains an important source of rural income in South East Asia. At the same time, Indonesia has become a hotspot for large-scale species extinction and a loss of biodiversity in favor of agricultural production. The present study sets out to assess the environmental performance of smallholder oil palm production with respect to biodiversity. Using a panel dataset that combines conventional farm data together with an account of plant diversity, we estimate a restricted hyperbolic environmental distance function. We integrate loss of biodiversity as an undesirable output into the production model which allows explaining shortfalls in environmental performance and the derivation of shadow prices of biodiversity conservation. We find a substantial environmental inefficiency, which is partly explained by both chemical and manual weeding practices, highlighting the potential for improvements in both the environmental and the economic dimension. Moreover, the value for conserving one species of the average biodiversity on a farmers plantation was 325 USD in 2018. Payments for ecosystem services schemes could be a viable policy response to conserve meaningful levels of biodiversity while simultaneously allowing smallholders to increase palm oil output. In general, addressing drivers of environmental performance in PES designs amplifies its effect without reducing output.

Vietnam's Payments for Forest Ecosystem Services scheme's puzzling role in protecting longstanding forests as deforestation rates rise

Research on payments for ecosystem services (PES) schemes indicates that few of them in fact implement full marketization, highlighting the need for better understanding of the performance of incompletely marketized PES models. One prominent example of a PES program with limited marketization is Vietnam's Payments for Forest Environmental Services (PFES) scheme, a payment for environmental services program that has been progressively rolled out in 45 provinces since 2008. The program is notable both for its spatial extent and governance structure, collecting funds primarily from taxes on water consumption in hydroelectric dams and water companies, which are then redistributed via contracts managed at provincial and national levels to protect, restore, and plant new forests. We assess the impact of PFES's impact on longstanding forest loss using matched two-way fixed effects models and matched multi-period difference-in-differences estimation. These methods both suggest that PFES restrains forest loss at a rate comparable to or greater than state-managed protected areas but impacts are weak or nonexistent until PFES has been established for over three years. Taken together, these findings provide further evidence PES-like programs can perform well in forest protection even if they lack full marketization.

Evaluating the determinants of participation in conservancy land leases and its impacts on household wealth in the Maasai Mara, Kenya: Equity and gender implications

Understanding the impact of conservation interventions on local communities is important in determining their effects on livelihoods and wellbeing. However, impacts are often not uniform and there are important equity dimensions when evaluating interventions. Therefore, in this paper, we investigate determinants of participation in conservation land leases in the Mara Conservancies in southern Kenya and its impact on household wealth. We find that land ownership determines who can participate in and benefit from conservancy land lease payments, and by how much. The design of the land lease payment scheme therefore has the potential to reinforce and, in cases, amplify existing inequities as it is built upon a legacy of unequal historical land distribution processes that limit the participation of women and poor landless households. We observed significantly higher incomes amongst participant households compared to non-participants, but these differences disappeared after propensity score matching. These results suggest that the differences were not caused by participation in conservancies. Our findings suggest that the design and outcomes of land-based conservation or payment for ecosystem services schemes should consider historic and existing land tenure systems if they are to reduce inequality.

Pricing rules for PES auctions: Evidence from a natural experiment

Payments for Ecosystem Service (PES) schemes increasingly use auctions to target funds to low-cost providers, aiming to increase value-for-money. To date, PES auctions have most often employed “Pay-as-Bid” (PaB) pricing, in which successful participants are paid the amount stipulated in their bid(s). Alternative pricing rules exist, such as the “Uniform Price” (UP) rule, in which successful bids receive the same per unit payment determined by the marginal bid. Despite being successfully applied in other settings, the use of UP pricing in PES auctions has been limited. We explore the impact of UP pricing in the context of a scheme incentivising farmers to reduce nutrient run-off. Following our intervention, the auction through which contracts were allocated to farmers switched from PaB to UP. Our analysis provides the first real-world, causal evidence on the effect of alternative auction pricing rules in this context. We find that UP pricing reduced mean bids, by 40%. A priori the impact on payments made to the farmers is ambiguous, yet we find these to be reduced by a similar amount. Moreover, the UP format reduces the incidence of costly bidding behaviours, updating and sniping, by approximately 50% and 30% respectively. These significant and substantial changes suggest wider adoption of UP pricing in PES auctions is likely warranted.

Socio-Hydrological Approach for Water Resource Management and Human Well-Being in Pinglin District, Taiwan

Despite being a limited resource, pollution, poor management, and other drivers like climate change make available water unsuitable and insufficient for human consumption and ecosystem maintenance. Therefore, a transdisciplinary approach is needed for managing this precious resource. The overall aim of this paper is to address water inequalities and improve human well-being using an integrated approach of key informant interviews, hydrological modeling, and the payment of ecosystem services (PES) scheme in Pinglin District, Taiwan. This site is an upstream area of Feicui Reservoir, which protects the downstream tap water supply. Key informant interviews were conducted to identify the gaps in and challenges to water resource management. This was followed by a scenario-based hydrological simulation using a Water Evaluation and Planning (WEAP) tool to project future water quality by the year 2050 (using biochemical oxygen demand and total coliform content as key indicator parameters) and to trace the factors responsible for water pollution. Survey analysis of key informant interviews depicts that this area is facing several challenges, such as lack of water infrastructure, agricultural subsidy, construction restrictions, etc., which cumulatively cause water scarcity in the upstream regions. On the other hand, hydrological simulation results show that population decline and climate change under an RCP 8.5 scenario will have an enormous negative impact on water quality. The concentrations of BOD and E. coli in river water will expand by 110.1% and 117.3%, respectively, by 2050 compared to 2018. Finally, the results of the study suggest that the PES scheme can play a positive role in enabling integrated water resource management. For example construction of a small-scale wastewater treatment plant in the upstream area will reduce the total E. coli concentration by up to 90%. While the initial cost of construction will be taken care of by the government, the operation and management cost of this infrastructure will be covered by people living downstream, who need to pay only $0.10 per year per person. The obtained results should be vital for both the stakeholders and decision-makers in this region.

Do individual PES buyers care about additionality and free-riding? A choice experiment

Based on a survey of the French population, this study investigates consumer preferences for forest ecosystem services (FES) provision towards efficiency and equity in the context of additionality, and differences in willingness to pay (WTP) for FES between a tax-based and a donation-based payments for ecosystem services (PES) scheme. We show that consumers prefer equity to strict additionality adherence, with this preference being significantly stronger among females. However, consumer preferences are heterogeneous, and respondents with a closer connection to forests express the opposite preference. Regarding WTP, we find no systematic difference between the two payment vehicles, though WTP does vary depending on how respondents perceive potential free-riding. When considering that non-contributors also benefit from a particular PES scheme, a small group perceived this as unfair and reacted by reducing their contribution. A second, significantly larger group interpreted this as an opportunity to contribute to the common good and showed a higher WTP, indicating a markedly altruistic attitude towards FES provision in French society. We conclude by discussing the role of altruism in PES, the dilemma posed by the partial economic and legal incompatibilities of additionality and equity, and the environmental impact of environmental credits when credit buyers do not account for additionality.

Everyday Environmental Justice in Payments for Ecosystem Services: Insights From Two Protected Areas in China

Currently, social justice for the management of ecosystem services is promoted widely in international communities. Efforts have increased to develop indicators for justice assessment, but these are relatively static forms of results-oriented analysis without much understanding of the dynamics and pluralities of local justice in the management of ecosystem services. This research uses a novel perspective of everyday environmental justice (EEJ) to examine local practices of environmental justice in two protected areas in China where two different payments for ecosystem services (PES) schemes have been implemented. It demonstrates EEJ as a useful, process-oriented analysis that provides a deeper understanding of peoples’ everyday lives and their environmental management practices within the varied contexts of local justice. Everyday practices of EEJ highlight the spatiotemporal dynamics and plurality of justice, thereby offering a broader and more explicit conception of the distributive, procedural and recognition dimensions of environmental justice in local contexts. The research calls on policymakers and researchers to consider the everyday practices of EEJ with a heightened understanding of the spatiotemporal dynamics of multidimensional justice.

Drivers of PES effectiveness: Some evidence from a quantitative meta-analysis

Payments for Environmental or Ecosystem Services (PES) schemes have become a popular tool to address environmental degradation and to promote sustainable management of ecosystem services. We use meta-regression analysis on a sample of 110 individual studies to investigate the determinants of the environmental effectiveness, defined as the probability to increase environmental services (ES) provision, of about 149 PES-schemes implemented worldwide. We find that increased effectiveness of PES schemes is strongly associated with periodical third-party monitoring, generic reference design and to a lesser extent results-based payments. We further study the determinants of PES additionality, defined as direct changes in ES provision induced by the PES scheme, compared to a baseline without PES, on a smaller sample of 41 studies from which we could obtain the necessary data. The results confirm the role of certain design variables, such as monitoring type, and raise a potential trade-off between enrolment and additionality in the assessment of PES effectiveness.

Fire-smart solutions for sustainable wildfire risk prevention: Bottom-up initiatives meet top-down policies under EU green deal

Fuel management for wildfire risk prevention generally lacks economic sustainability. In marginal areas of southern Europe, this limits fuel treatment programs from reaching the critical mass of required treated area to modify landscape flammability, the fire regime and its impacts.This study investigates key fuel management initiatives for wildfire risk prevention in southern EU countries. We compared local approaches through a bottom-up selection of 38 initiatives, which we analyzed systematically through a set of fire-smart criteria: sustainability, cost-benefit ratio, synergies and inter-sectoral cooperation, integration between strategic prevention planning and multiple land governance goals (e.g., rural development, biodiversity conservation, energy supply), innovation and knowledge transfer, and adaptive management.We summarized lessons learned from the most innovative initiatives, by identifying solutions and functional approaches for building sustainable fuel management at the landscape scale, under fire-smart management principles. These make synergistic use of private, public and European resources to activate value chains that valorize the products, by-products and services generated by fuel management activities and their positive externalities on ecosystem services. The multiple mechanisms include fire-marketing, Payment for Ecosystem Services schemes, specific taxes, or environmental compensatory measures. These mechanisms catalyze the interest of multiple stakeholders (economic actors, private owners, land and fire management agencies) improving the cost-efficiency of landscape fuel management.We contend that the EU Green Deal offers the political backing and framework (mainstreaming of EU strategies and funding opportunities) to enable the replication of documented fire-smart models and functional approaches to wildfire risk prevention.

Small tradeoffs between social equity and conservation outcomes in a freshwater payment for ecosystem services scheme.

Conservation programs around the world aim to balance social equity, economic efficiency, and conservation outcomes. Tradeoffs among these three objectives necessarily exist but have been quantified in only a handful of systems. Here, we use a multi-objective mathematical optimization model in a large, water-limited river basin to quantify these tradeoffs in a freshwater payment for ecosystem services (PES) program aimed at establishing environmental flows (e-flows). Across a range of budgetary and future climate scenarios, we find that tradeoffs between social equity and conservation outcomes are small. We also show that payment schemes in which incentives are allocated to a single water use sector are much less cost-effective than schemes in which incentives are allocated among multiple sectors. Thus, allocating payments equally among agricultural, municipal, and industrial sectors can be both more equitable and more cost-effective. Overall, our results illustrate how some carefully designed conservation programs may be able to achieve a triple bottom line of social equity, economic efficiency, and conservation effectiveness.

Assessing Community Readiness for Payments for Ecosystem Service Schemes for Tropical Primary Forest Protection in the Democratic Republic of Congo

Primary forest conservation is essential for limiting climate change, for meeting conservation objectives, and the Sustainable Development Goals. Schemes that compensate communities for forgone extractive uses are important policy tools, but effective deployment demands an understanding of local deforestation drivers and host communities’ preferences. We use Q-methodology to reveal discourses present in three communities in the Democratic Republic of Congo. Our results reveal three factors with a common emphasis on forest conservation and preferences for compensation in the form of social investments, rather than cash. The main contrasts were in attitudes towards farming. The first discourse, we call conservationist—open to ideas, displayed a commitment to learning better practices for community material benefit in service of forest conservation. The second discourse, which demonstrated greater confidence in their capacity to support livelihoods from farming, we call aspirational artisans. The third, which was acutely aware of the impact of their farming on forest conservation, we called passive, conflicted farmers. We also demonstrate an aspiration for the continued development of farming amongst participants, which although still correlated with preferences for forest conservation, may lead to compensation schemes inadvertently stirring future land use tensions if design does not reconcile agricultural development and conservation.

The Dynamics of Implementing Payment for Ecosystem Services Scheme in Lake Naivasha Basin Ecosystem, Kenya

Lake Naivasha Basin is located in Nakuru and Nyandarua counties in the Republic of Kenya. It is an important ecosystem to the economy of Kenya, consistently contributing upwards of 1% of the national Gross Domestic Production. However, this landscape is continuously and rapidly degrading due to intensive land use practices and land fragmentation in spite of the existence of various natural resource management policies in Kenya. The promotion of Payment for Ecosystem Services (PES) as a policy option to foster ecosystems sustainability by increasing the capacity of government authorities and local communities in Kenya to conserve riparian and forest ecosystems so as to reduce the vulnerability of dependent communities and production enterprises to the observed and anticipated effects of climate change is implied in the key environmental and natural resources policies in Kenya. We examine whether the Lake Naivasha Basin Payment for Ecosystem Services (LNB-PES) scheme embodied the critical characteristics of an effective PES mechanism and if it achieved the desired ecological and livelihood results. A total of 1,191 heads of households and 11 key informants were interviewed for this study. The study results indicate that the LNB-PES scheme had some functional and conceptual inadequacies although it achieved remarkable adoption and compliance by participating farmers. Based on these results, we recommend that a new PES scheme with a conditionalities enforcement mechanism be initiated for the LNB with a view to informing the mainstreaming of the concept of enforceable PES in the existing policy framework, the development of a national or basin-level PES policy, and, support watershed restoration and climate change adaptation through the provision of forest technical extension services to land owners for the creation of woodlots and other watershed protection initiatives at farm level.
