Only 5% of global threat data sets meet a “gold standard”
Consumption of globally traded agricultural commodities like soy and palm oil is one the primary causes deforestation biodiversity loss in some world's most species-rich ecosystems. However, complexity global supply chains has confounded efforts to reduce impacts. Companies governments with sustainability commitments struggle understand their own sourcing patterns, while activities more unscrupulous actors are conveniently masked by opacity trade. We combine state-of-the-art material flow,...
The estimated period in which human colonization of Madagascar began has expanded recently to 5000–1000 y B.P., six times its range 1990, prompting revised thinking about early migration sources, routes, maritime capability and environmental changes. Cited evidence age includes anthropogenic palaeoecological data 2500–2000 megafaunal butchery marks 4200–1900 B.P. OSL dating 4400 the Lakaton'i Anja occupation site. Using large samples newly-excavated bone from sites was earlier dated >2000 we...
Biodiversity conservation and poverty alleviation are two of the world's major challenges, search for synergies in pursuit both agendas is enshrined their respective global policy frameworks – Convention on Biological Diversity Millennium Development Goals. The 'conservation–poverty debate' has featured prominently discourses since 1980s (Roe 2008), focusing primarily issues such as impact activities (particularly protected areas) affected local communities, role organizations complex...
Abstract Further progress in reducing biodiversity loss relies on the improved quantification of connections between drivers habitat and subsequent impacts. To this end, impact metrics should be able to report linked trends specific human activities changes state, accounting for both ecology different species cumulative effects historical losses. These characteristics are not currently captured within a single metric. Here, we develop globally applicable methodological framework that uses...
Land use is a key driver of the ongoing biodiversity crisis and therefore also major opportunity for its mitigation. However, appropriately considering diversity land-use actors activities in conservation assessments planning challenging. As result, top-down policy are often criticized lack contextual nuance widely acknowledged to be required effective just action. To address these challenges, we have developed conceptually consistent, scalable land system typology demonstrated usefulness...
Conceptual models suggest a link between spatial heterogeneity, diversity, and resilience, but few empirical studies exist to demonstrate such an ecological relationship. In this study, we investigated the nature of heterogeneity resilience two forest fragments from Madagascar's highly endangered littoral forest, nearby sites in surrounding ericoid grassland. This ecosystem has been subjected number large environmental disturbances over last 6000 years, including late Holocene sea‐level rise...
Abstract Aim There remains some uncertainty concerning the causes of extinctions Madagascar’s megafauna. One hypothesis is that they were caused by over‐hunting humans. A second their extinction was both environmental change and hunting. This paper systematically addresses through examination two new pollen records from south‐eastern Madagascar alongside other published across island. Location South‐eastern Madagascar. Methods We reconstructed past vegetation fire dynamics over 6000 years at...
ABSTRACT Aim Coastal biodiversity hotspots are globally threatened by sea‐level rise. As such it is important to understand how ecosystems resist, respond and adapt Using pollen, geochemistry, charcoal diatom records in conjunction with previously published palaeoclimatic records, we investigated the mechanism, interactions ecosystem response resilience of Madagascar's littoral forest late Holocene Location Sediment sequences were collected along south‐east coast Madagascar two adjacent...
Abstract A long‐held assumption about Madagascar is that all its open vegetation and forest fragments represent anthropogenically degraded landscapes. Further, forests are believed to lack regenerative capacity following extirpation. This article presents a different ecological framework for southeast Madagascar, region with diverse habitats (humid, littoral, transitional forests) exceptional biodiversity. Recently published reconstructions of change at millennial scales indicate the mosaic...
Occurrences of grasslands in regions that climatically can support forests are commonly attributed to previous human activity. In mid high latitudes this assumption is often correct. For example, North America and north-west Europe numerous palaeoecological analyses have revealed the role pre-historic historic humans opening up forested landscapes development (e.g. Motzkin & Foster, 2002). These `cultural landscapes' now viewed as important for conservation there many initiatives conserve...
Abstract Boundary organizations are situated between science, policy, and practice have a goal of supporting communication collaboration among these sectors. They been promoted as way to improve the effectiveness conservation efforts by building stronger relationships scientists, policy makers, industry, practitioners (Cook et al. 2013). Although their promise has discussed in theory, work expectations for boundary less defined practice. Biodiversity is characterized complexity, uncertainty,...
Madagascar experienced environmental change during the Late-Holocene, and relative importance of climatic anthropogenic drivers is still subject an ongoing debate. Using palaeoecological records from southwest region at Lake Longiza, we provide additional to elucidate complex history island identify changes that occurred in tropical dry forest Late-Holocene. The data showed vegetation associated with climate variability until AD 900 as reflected by variation grass, dry-adapted taxa,...
Planting trees is proposed as an important climate mitigation tool, but can be detrimental to biodiversity and livelihoods if not carefully planned managed, with landscape history in mind. In Madagascar, deforestation of concern, a threat forest-adapted biota. However, much Madagascar’s harbours ancient mosaic open ecosystems that are home unique suites flora fauna provide wide range ecosystem services. Though guidelines for ecologically socially responsible reforestation emerging, the...
Evaluation has so much potential for learning, co-creation, and collaboration around more inclusive regenerative programs and, ultimately, systems. Yet, currently, evaluations are often experienced as controlling frustrating add-ons. Inspired by developmental evaluation, we have experimented with generative methods to make evaluation a space stakeholders come together, re-connect, re-fresh the purpose of re-view design. We see that such approach can help (1) express co-construct systemic...
