Deliverable D3.3 EU Horizon 2020 ESMERALDA Project, Grant agreement No. 642007. The aims of The Report are: 1) to gather the latest knowledge of biophysical mapping and assessment of the ecosystem services, including methods, data, tools, and software commonly used; 2) based on the above findings, to suggest a harmonised methodology describing ho...
Article
Full-text available
Currently, human society is predominantly powered by fossil fuels—coal, oil and natural gas—yet also ultimately depends on goods and services provided by biodiversity. Fossil fuel extraction impacts biodiversity indirectly through climate change and by increasing accessibility, and directly through habitat loss and pollution. In contrast to the ind...
Article
Full-text available
Over the past decades, a number of national policies and international conventions have been implemented to promote the expansion of the world’s protected area network, leading to a diversification of protected area strategies, types and designations. As a result, many areas are protected by more than one convention, legal instrument, or other effe...

Article
Full-text available
Competition for land is increasing as a consequence of the growing demands for food and other commodities and the need to conserve biodiversity and ecosystem services. Land conversion and the intensification of current agricultural systems continues to lead to a loss of biodiversity and trade-offs among ecosystem functions. Decision-makers need to...
Technical Report

The experimental ecosystem accounts for Uganda presented in this report follow on from a recent publication which explored approaches to accounting for species-level biodiversity and a feasibility study of applications using existing data in Uganda. The accounts compiled respond to policy entry points for biodiversity and ecosystem related concerns...
Article
Full-text available
Decision-makers aiming to improve food security, livelihoods and resilience are faced with an uncertain future. To develop robust policies they need tools to explore the potential effects of uncertain climatic, socioeconomic, and environmental changes. Methods have been developed to use scenarios to present alternative futures to inform policy. Nev...
Article
Crossing “safe” limits for biodiversity loss The planetary boundaries framework attempts to set limits for biodiversity loss within which ecological function is relatively unaffected. Newbold et al. present a quantitative global analysis of the extent to which the proposed planetary boundary has been crossed (see the Perspective by Oliver). Using o...
Article
Full-text available
Flagship species are traditionally large, charismatic animals used to rally conservation efforts. Accepted flagship definitions suggest they need only fulfil a strategic role, unlike umbrella species that are used to shelter cohabitant taxa. The criteria used to select both flagship and umbrella species may not stand up in the face of dramatic fore...
Conference Paper
The great crested newt (Triturus cristatus) has undergone substantial declines in the UK and elsewhere in Europe through habitat loss and fragmentation. It is protected at European level under the provisions of the Conservation of Habitats and Species Regulations 2010 (as amended) and the “Habitats Directive”. The species is also protected under th...
Technical Report
Full-text available
The great crested newt is declining in the United Kingdom despite full European-level protection. Reporting on the species’ status to the EU is carried out at UK level but nature conservation is a devolved function. Knowledge and quantification of the great crested newt’s status in Wales will therefore form part of future aggregated UK-level report...

Website: https://naturemap.earth/ Countries need integrated maps of biodiversity and ecosystem services, including carbon, to design and implement national policies for halting and reversing the loss of biodiversity and for curbing net greenhouse gas emissions from land use. Yet, such maps are in short supply. Today marks the first release of Nature Map’s freely available global maps of terrestrial biodiversity and ecosystem carbon stocks, designed to support governments in policy design.
Project
Undertake a global update of data on trends in wetland extent with a particular focus on data gaps in Latin America and the Caribbean. This work will enhance the quality, coverage and resolution of the underlying data within the WET Index and improve its utility for global, regional and national reporting and decision-making. The resulting analysis will feed into the Global Wetland Outlook of the Ramsar Convention on Wetlands, 2018.
