   Sustainable coffee production faces growing environmental and economic pressures, particularly under climate change and volatile markets. This study examines Honduran coffee farmers’ willingness to adopt sustainable land-sparing practices that integrate natural forests into production systems. Using a discrete choice experiment with 600 farmers in the Yoro region, we estimated preferences for carbon payments, coffee price premia, and technical training. Results show that financial incentives strongly influence adoption, with compensation requirements rising, the proportion of farmland allocated to forest increases. Farmers with higher incomes, existing forest cover, or prior experience with sustainable methods were more willing to participate. In contrast, lower-income farmers required greater payments due to risk aversion and opportunity costs. Findings highlight the importance of incentive structures that combine economic rewards with technical support, providing valuable insights for policies and programs that promote sustainable coffee landscapes in Central America.

2. The importance of communal forests in carbon storage: Using and destabilizing carbon measurement in understanding Guatemala's payments for ecosystem services

   https://doi.org/10.1111/cag.12810

   Payments for ecosystem services (PES) are a conservation initiative that offer payments to people who own or manage lands that provide desired ecosystem services. Utilizing mixed methods, I examine how PES in the form of government‐issued forestry incentives interact with land tenure to affect carbon storage in Guatemala's Western Highlands. Land tenure is a larger determining factor for carbon storage than payments, as communal forests managed by Indigenous Maya K'iche' communities have significantly higher carbon stocks than private landholdings in these same communities. No statistically significant differences were found in carbon stocks between incentivized and non‐incentivized plots, and participants enrolled only a fraction of their land, likely prioritizing enrollment of degraded plots. These results indicate the importance of using both social and physical science methods to understand the physical outcomes and social context of forest management. I also reflect on why carbon storage is often prioritized, drawing on a critical physical geography framework to analyze carbon accounting methods. Measuring carbon storage gives us the tools to describe the success of communal forest management, yet I also caution relying on the quantification of ecosystem services as a method for landscape valuation and suggest avoiding prioritizing carbon storage and sequestration.

3. Impermanence and failure: the legacy of conservation-based payments in Sumatra, Indonesia

   https://doi.org/10.1088/1748-9326/ac6437  

   Erbaugh, James T. (April 2022, Environmental Research Letters)

   Abstract Projects that pay communities or individuals to conserve natural areas rarely continue indefinitely. When payments cease, the behaviors they motivate can change. Previous research on conservation-based payments recognizes the impermanence of conservation success, but it does not consider the legacy of payments that failed to effect change. This research assesses impermanence and failure by investigating the legacy of village-level conservation payments made through one of the largest Integrated Conservation and Development Projects in Indonesia. The Kerinci-Seblat Integrated Conservation and Development Project aimed to conserve forest area and promote local development through voluntary conservation agreements (VCAs) that provided payments for pro-conservation pledges and activities from 2000 through 2003. Project documentation and previous research find that payments failed to incentivize additional forest conservation, producing nonsignificant differences in forest-cover change during the project period. To examine the legacy of these payments in the post-project period, this research uses matched difference-in-differences and triple differences models to analyze forest cover change in villages (n= 263) from 2000 through 2016 as well as matched binary logistic regression models to assess enduring differences in household (n= 1303) livelihood strategies within VCA villages in 2016. The analysis finds that VCA villages contained significantly more forest loss than the most similar non-VCA villages outside the national park, and greater payments predict increased forest loss in the post-project period. In addition, farming high-value tree crops and cultivating private land were the most important attributes for modeling VCA affiliation among randomly selected households. These results demonstrate that, after payments ceased, project failures increased in severity over time.Those who design and implement conservation-based payments bear great responsibility to ensure their projects are informed by local voice, align with community preferences, and provide sufficient benefits, lest they result in a conservation legacy of increased failure.

4. The natural capital of seagrass beds in the Caribbean: evaluating their ecosystem services and blue carbon trade potential

   https://doi.org/10.1098/rsbl.2023.0075  

   Shayka, Bridget F; Hesselbarth, Maximilian_H K; Schill, Steven R; Currie, William S; Allgeier, Jacob E (June 2023, Biology Letters)

   Seagrass beds provide tremendous services to society, including the storage of carbon, with important implications for climate change mitigation. Prioritizing conservation of this valuable natural capital is of global significance, and including seagrass beds in global carbon markets through projects that minimize loss, increase area or restore degraded areas represents a mechanism towards this end. Using newly available Caribbean seagrass distribution data, we estimated carbon storage in the region and calculated economic valuations of total ecosystem services and carbon storage. We estimated the 88 170 km²of seagrass in the Caribbean stores 1337.8 (360.5–2335.0, minimum and maximum estimates, respectively) Tg carbon. The value of these seagrass ecosystems in terms of total ecosystem services and carbon alone was estimated to be $255 billion yr⁻¹and $88.3 billion, respectively, highlighting their potential monetary importance for the region. Our results show that Caribbean seagrass beds are globally substantial pools of carbon, and our findings underscore the importance of such evaluation schemes to promote urgently needed conservation of these highly threatened and globally important ecosystems.

5. Spatial and Ecological Farmer Knowledge and Decision-Making about Ecosystem Services and Biodiversity

   Amid climate change, biodiversity loss and food insecurity, there is the growing need to draw synergies between micro-scale environmental processes and practices, and macro-level ecosystem dynamics to facilitate conservation decision-making. Adopting this synergistic approach can improve crop yields and profitability more sustainably, enhance livelihoods and mitigate climate change. Using spatially explicit data generated through a public participatory geographic information system methodology (n = 37), complemented by spatial analysis, interviews (n = 68) and focus group discussions (n = 4), we explored the synergies between participatory farmer-to-farmer agroecology knowledge sharing, farm-level decisions and their links with macro-level prioritization of conservation strategies. We mapped farm conditions and ecosystem services (ES) of two village areas with varying knowledge systems about farming. Results of the farm-level analysis revealed variations in spatial perception among farmers, differences in understanding the dynamics of crop growth and varying priorities for extension services based on agroecological knowledge. The ES use pattern analysis revealed hotspots in the mapped ES indicators with similarities in both village areas. Despite the similarities in ES use, priorities for biodiversity conservation align with farmers’ understanding of farm processes and practices. Farmers with training in agroecology prioritized strategies that are ecologically friendly while farmers with no agroecology training prioritized the use of strict regulations. Importantly, the results show that agroecology can potentially contribute to biodiversity conservation and food security, with climate change mitigation co-benefits. The findings generally contribute to debates on land sparing and land sharing conservation strategies and advance social learning theory as it pertains to acquiring agroecological knowledge for improved yield and a sustainable environment.
