The Scientific assessments and monitoring are a crucial part of any effective decision-making process. The scientific bodies
of the MEAs (Multilateral Environmental Agreements) facilitate evidence-based decision-making to address the societal
challenges in sustainable development. Within the MEAs, assessment reports and scientific evidences evaluate consequences of
real policy options to select the best response.
In the context of MEAs on biodiversity conventions, there are several initiatives and organizations contribute to bring
information together and synthesize and analyses it for policy making. The Millennium Ecosystem Assessment (MA) and the
Global Biodiversity Outlook (GBO) among others are the most comprehensive assessments on biodiversity to date. These global
assessments have been designed and lunched to respond the scientific information of MEAs in the biodiversity cluster and to
track causes and consequences of anthropogenic ecosystem changes. However, some evaluations concluded that those models
have limited impact on policy formulation and decision-making.
In this regard, the lack of fully developed science-assessment mechanisms at the international level, and a meaningful
engagement between global science and international politics required an effective science-policy interface among the biodiversity
cluster. Indeed, by enhancing interfaces it enables more coherent and consistent decision-making on biodiversity at the global,
regional and national level.
This paper, considers the existing models and tools regarding global assessments in the science-policy interface on
biodiversity and ecosystem services, identifies its challenges and outlines new platforms to fill in the gaps for creating scientifically
credible and policy-relevant decision-making towards biodiversity conservation.
