Potentially, ecosystems show nonlinear responses to land-use intensification that would open management options with limited ecological losses but satisfying economic gains. However, multidisciplinary studies to quantify ecological losses and socioeconomic tradeoffs under different management options are rare. Here, we evaluate opposing land use strategies in cacao agroforestry in Sulawesi, Indonesia, by using data on species richness of nine plant and animal taxa, six related ecosystem functions, and on socioeconomic drivers of agroforestry expansion. Expansion of cacao cultivation by 230% in the last two decades was triggered not only by economic market mechanisms, but also by rarely considered cultural factors. Transformation from near-primary forest to agroforestry had little effect on overall species richness, but reduced plant biomass and carbon storage by ≈75% and species richness of forest-using species by ≈60%. In contrast, increased land use intensity in cacao agroforestry, coupled with a reduction in shade tree cover from 80% to 40%, caused only minor quantitative changes in biodiversity and maintained high levels of ecosystem functioning while doubling farmers' net income. However, unshaded systems further increased income by ≈40%, implying that current economic incentives and cultural preferences for new intensification practices put shaded systems at risk. We conclude that low-shade agroforestry provides the best available compromise between economic forces and ecological needs. Certification schemes for shade-grown crops may provide a market-based mechanism to slow down current intensification trends."],["dc.identifier.doi","10.1073/pnas.0608409104"],["dc.identifier.gro","3148984"],["dc.identifier.scopus","2-s2.0-34247633507"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/5623"],["dc.identifier.url","http://www.scopus.com/inward/record.url?eid=2-s2.0-34247633507&partnerID=MN8TOARS"],["dc.language.iso","en"],["dc.notes.intern","Faust Crossref Import"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.eissn","1091-6490"],["dc.relation.issn","0027-8424"],["dc.title","Tradeoffs between income, biodiversity, and ecosystem functioning during tropical rainforest conversion and agroforestry intensification"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Yet, significant conceptual and methodological gaps exist, especially for urban ecosystems. We analyzed perceptions of cultural ecosystem services in the urban context of Berlin, based on qualitative research methods. Using expert and problem-centered interviews, we show how cultural ecosystem services are understood and which focus areas were emphasized. We compared our inductive codes with the Millennium Ecosystem Assessment. While our findings show supporting evidence for the Millennium Ecosystem Assessment classification, some categories had to be substituted and others adjusted to local citizen understandings. The results reveal a variety of intricate cultural ecosystem service perceptions. Hence, selecting and emphasizing only a few services without prior studies could misinform decision-makers and lead to biased policy outcome. Regionally specific perceptions of cultural benefits from urban green are important information for planning processes. Cultural ecosystem services could be one way to achieve awareness of socio-ecological aspects, as our results show linkages between cultural ecosystem services and urban social sustainability.

High deforestation rates and a politically unstable recent past indicate a problematic setting for conservation efforts. Here, we studied a forest-town gradient along four villages between a population centre (i.e., Siem Reap) and the forest of the Phnom Kulen National Park in rural north-western Cambodia. We analysed whether rural communities' dependence on forest resource extraction precludes strict forest and national park protection. A total of 149 structured interviews in four local communities revealed a rapid advance of a typical forest frontier. With increasing distance to town, small businesses as income sources decreased, whereas forest-related activities and slash-and-burn agriculture increased. Local residents were strongly dependent on forest resource extraction, especially on fuel wood, and land use for slash-and-burn agriculture as cash and subsidence income sources. Most forest resources-especially large-bodied wildlife species and timber, both used predominantly by households with a better asset-based index of wealth-were rated as difficult to find. No significant relationship between the use of non-timber forest products and wealth could be identified. We conclude that the importance of forest resources increases with proximity to the forest, however, households rely on forest resources for income supplementation rather than for primary income. To prevent the continued degradation of forests, their resources and related biodiversity, greater community engagement and capacity building in sustainable forest management practices combined with stricter law enforcement, and protection from harvesters from outside of the local communities are required."],["dc.description.sponsorship","Zoo Muenster, Germany"],["dc.identifier.isi","000308417500007"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/26184"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","0217-2445"],["dc.title","SOCIO-ECONOMIC CONTEXT OF FOREST BIODIVERSITY USE ALONG A TOWN-FOREST GRADIENT IN CAMBODIA"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]

Species richness of trees, fungi, invertebrates, and vertebrates did not decrease with yield. Moderate shade, adequate labor, and input level can be combined with a complex habitat structure to provide high biodiversity as well as high yields.

Impacts of climate change, demographic shifts and conservation of biodiversity should be incorporated into urban green space planning to balance for the increasing development pressure of cities. Urban green spaces provide multiple ecosystem service benefits to diverse social groups. In this paper, we analyzed inhabitant perceptions of cultural ecosystem services provided by urban green spaces in the city of Berlin based on a face-to-face questionnaire (n = 558). As analysis tool, we used proportionate cluster sampling and focused on non-monetary statements on the perceived importance of a broad spectrum of cultural ecosystem services. Results show that cultural ecosystem services can be perceived through bundles and that those bundles may have negative influence on each other. The perceived importance of cultural ecosystem services was influenced by spatial and social factors: Older inhabitants living in periurban areas preferred cultural ecosystem services related to nature experiences. Younger inner city dwellers tended to prefer cultural ecosystem services facilitating social interactions. Those diverging perceptions should to be taken into account through urban development strategies to create a socially just and sustainable city planning in the face of global environmental changes. The ecosystem service framework can be one tool to facilitate a more participatory planning process to find solutions for urban sustainability challenges."],["dc.identifier.doi","10.1016/j.landurbplan.2018.03.017"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/61879"],["dc.language.iso","en"],["dc.relation.issn","0169-2046"],["dc.title","Diverging perceptions by social groups on cultural ecosystem services provided by urban green"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]
