Ecosystem approach

Effective governance is a fundamental requisite for Ecosystem-based Adaptation (EbA). CLIMA is a practical tool to plan, execute, evaluate, and improve governance in the context of specific initiatives, actions and measures for climate change adaptation and ecosystem management. CLIMA helps generate recommendations for the development and implementation of action plans applied to situations at multiple spatial and temporal scales.

La gobernanza efectiva es un requisito fundamental para la adaptación basada en ecosistemas (AbE). CLIMA es una herramienta practica para la planificacion, la implementacion, la evaluacion y la mejora de la gobernanza en el contexto de iniciativas, proyectos, acciones y medidas especfficas para la adaptacion al cambio climatico y la gestion de los ecosistemas. CLIMA pretende aportar recomendaciones para el desarrollo y la implementacion de planes de accion aplicados a situaciones en multiples escalas espaciales y temporales.

Aquaculture production has very significantly increased in tonnage and value over the last decades. It is seen as a potential solution to replace the declining wild fishery stocks. This publication is a first attempt to examine aquaculture systems within the recent framework of the IUCN Global Standard for Nature-based Solutions (NbS). It reviews the critical contextual situation, highlighting major issues related to climate change, biodiversity losses and endangered marine ecosystems.

This report has been prepared as part of an effort by IUCN to define its position on Nature-based Solutions (NbS) and plan for future work to advance this concept and support effective implementation of NbS to enhance ecosystem services provision and address societal challenges. The report proposes a definitional framework for NbS, including a set of general principles for any NbS intervention. The report also defines the scope of NbS as an umbrella concept embracing a number of different ecosystem-based approaches.

Management of transboundary waters in increasingly becoming more challenging, and climate change is likely to exacerbate these pressures. Not least because climate change is a global issue, adaptation will require an international response. This book aims to identify issues, both theoretical and practical, that States face in establishing cooperative transboundary mechanisms to effectively adapt water management to climate change.

After a short introduction of the IUCN Commission on Ecosystem Management (CEM), the present presentation develops the application of the ecosystem approach by the military sector, in particular in relation to peace-support operations and reconstruction programmes. It describes a simple model of 4 steps. The first step deals with the physical system (“the ecosystem”), the second step with the use of the ecosystem and the third step with its management (institutions and regulations).

This paper is a summary of a longer and fully referenced document by the same authors. It is an updated version of the draft guidelines developed by this group at a workshop and meeting held in Costa Rica in June 2011 to initiate a more formal and iterative process for Ecosystem Based Adaptation Guidelines which can be discussed at various international and regional events.
