AbstractPolicy-makers are paying increasing attention to ecosystem services, given improved understanding that they underpin human well-being, and following their integration within the Aichi Targets of the Convention on Biological Diversity. Decision-makers need information on trends in biodiversity and ecosystem services but tools for assessing the latter are often expensive, technically demanding and ignore the local context. In this study we used a simple, replicable participatory assessment approach to gather information on ecosystem services at important sites for biodiversity conservation in Nepal, to feed into local and national decision-making. Through engaging knowledgeable stakeholders we assessed the services delivered by Nepal's 27 Important Bird and Biodiversity Areas, the pressures affecting services through impacts on land cover and land use, and the consequences of these for people. We found that these sites provide ecosystem services to beneficiaries at a range of scales but under current pressures the balance of services will change, with local communities incurring the greatest costs. The approach provided valuable information on the trade-offs between ecosystem services and between different people, developed the capacity of civil society to engage in decision-making at the local and national level, and provided digestible information for Nepal's government. We recommend this approach in other countries where there is a lack of information on the likely impacts of land-use change on ecosystem services and people.

SummaryLand-use intensification has contrasting effects on different ecosystem services, often leading to land-use conflicts. Multiple studies, especially within the ‘land-sharing versus land-sparing’ debate, have demonstrated how landscape-scale strategies can minimise the trade-off between agricultural production and biodiversity conservation. However, little is known about which land-use strategies maximise the landscape-level supply of multiple ecosystem services (landscape multifunctionality), a common goal of stakeholder communities. Here, we combine data collected from 150 grassland sites with a simulation approach to identify landscape compositions, with differing proportions of low-, medium-, and high-intensity grasslands, that minimise trade-offs between the four main grassland ecosystem services demanded by stakeholders: biodiversity conservation, aesthetic value, productivity and carbon storage.We show that optimisation becomes increasingly difficult as more services are considered, due to varying responses of individual services to land-use intensity and the confounding effects of other environmental drivers. Thus, our results show that simple land-use strategies cannot deliver high levels of all services, making hard choices inevitable when there are trade-offs between multiple services. However, if moderate service levels are deemed acceptable, then strategies similar to the ‘land-sparing’ approach can deliver landscape multifunctionality. Given the sensitivity of our results on these factors we provide an online tool that identifies strategies based on user-defined demand for each service (https://neyret.shinyapps.io/landscape_composition_for_multifunctionality/). Such a tool can aid informed decision making and allow for the roles of stakeholder demands and biophysical trade-offs to be understood by scientists and practitioners alike.

BackgroundConserving both biodiversity and ecosystem services is a major goal of the Convention on Biological Diversity. Hotspots for biodiversity in the Andes significantly overlap with areas with dense human populations that sustain their economy through agricultural production. Therefore, developing management forms that reconcile food provisioning services—such as agriculture—with biodiversity conservation must be addressed to avoid social conflicts and to improve conservation in areas where biodiversity co-occurs with other ecosystem services. Here, we present a high-resolution conservation plan for vascular plants and agriculture in the Ecuadorian Dry Inter-Andean Valleys (DIAV) hotspot. Trade-offs in conserving important areas for both biodiversity and agriculture were explored.MethodsWe used a dataset containing 5,685 presence records for 95 plant species occurring in DIAVs, of which 14 species were endemic. We developed habitat suitability maps for the 95 species using Maxent. Prioritization analyses were carried out using a conservation planning framework. We developed three conservation scenarios that selected important areas for: biodiversity only, agriculture only, and for both biodiversity and agriculture combined.ResultsOur conservation planning analyses, capture 33.5% of biodiversity and 11% of agriculture under a scenario solely focused on the conservation ofbiodiversity. On the other hand, the top 17% fraction of theagriculture onlyscenario captures 10% of biodiversity and 28% of agriculture. When biodiversity and agriculture were considered in combination, their representation varied according to the importance given to agriculture. The most balanced solution that gives a nearly equal representation of both biodiversity and agriculture, was obtained when agriculture was given a slightly higher importance over biodiversity during the selection process.DiscussionThis is the first evaluation of trade-offs between important areas for biodiversity and agriculture in Ecuadorian DIAV. Our results showed that areas with high agricultural productivity and high biodiversity partly overlapped. Our study suggests that a land-sharing strategy would be appropriate for conserving plant diversity and agriculture in the DIAV. Overall, our study reinforces the idea that friendly practices in agriculture can contribute to biodiversity conservation.

Intensively Managed

AbstractAgricultural management should consider multiple services and stakeholders. Yet, it remains unclear how to guarantee the provision of ecosystem services that reaches stakeholders’ demands, especially considering the observed biodiversity decline and the current global change predictions that may affect food security. Here, we use a model to examine how landscape composition – fraction of semi-natural habitat (SNH) – affects biodiversity and crop production services in intensively-managed agricultural systems. We analyse three groups of stakeholders assumed to value different ecosystem services most – individual farmers (crop yield per area), agricultural unions (landscape production) and conservationists (biodiversity). We find that trade-offs among stakeholders’ demands strongly depend on the degree of pollination dependence of crops, the strength of environmental and demographic stochasticity, and the relative amount of an ecosystem service demanded by each stakeholder, i.e. function thresholds. Intermediate amounts of SNH can allow for the delivery of relatively high levels of the three ecosystem services. Our analysis further suggests that the current levels of SNH protection lie below these intermediate amounts of SNH in intensively-managed agricultural landscapes. Given the worldwide trends in agriculture and global change, these results suggest ways of managing landscapes to reconcile the demands of several actors and ensure for biodiversity conservation and food production.

AbstractMarine protected areas (MPAs) are key to averting continued loss of species and ecosystem services in our oceans, but concerns around economic trade-offs hamper progress. Here we provide optimized planning scenarios for global MPA networks that secure species habitat while minimizing impacts on fisheries revenues. We found that MPA coverage requirements differ vastly among nations, and that two-thirds of nations benefit economically from a collaborative approach. Immediate global protection of marine biodiversity habitat comes with losses of ~19% of total fisheries revenues, but international cooperation in concert with high seas protection improves economic losses for most countries, safeguards all species, and could save ~5B USD annually worldwide. Nations and fishery economies both share benefits from a coordinated approach to conserving marine biodiversity, with direct relevance to current international policies.

Ecological management based on the ecosystem approach promotes ecological protection and the sustainable use of natural resources. We developed a quantitative approach to identify the ecological function zones at the country-scale, through integrating supply and demand of ecosystem services. We selected the biologically diverse hotspot of Baoxing County, which forms a part of the Sichuan Giant Panda World Heritage Site, to explore the integration of ecosystem services supply and demand for ecosystem management. Specifically, we assessed the various support, provision, regulating, and cultural services as classified by the Millennium Ecosystem Assessment. We applied the InVEST (Integrated Valuation of Ecosystem Services and Trade-offs) model to spatially map habitat quality, water retention, and carbon sinks, and used statistical data to evaluate food products, animal husbandry, and product supply services. We then quantified the demands for these services in terms of population, protected species, hydropower, water, and land use. The relationship between areas of supply and areas of demand was discussed for each township, and the spatial variability in the supply–demand relationship was also considered. As a result, we spatially divided the county into six ecological functional areas, and the linkages between each region were comprehensively discussed. This study thus provides a detailed methodology for the successful implementation of an ecosystem management framework on a county-scale based on the spatial partitioning of supply and demand.
