The expansion of our towns and cities, development of new infrastructure, and ongoing resource extraction and energy generation, must be carefully managed to minimise impact on the natural world upon which we all rely. Impact mitigation, including avoidance, and ecological compensation, are key tools for balancing development with environmental outcomes that benefit nature and people.

The Impact Mitigation and Ecological Compensation (IMEC) thematic group, under the IUCN Commission on Ecosystem Management, aims to develop and disseminate guidance around implementation of the mitigation hierarchy and ecological compensation. It will also perform ongoing case study reviews of policy and practice regarding mitigation and compensation design, governance, financing and implementation, building upon significant existing experience and lessons learnt by numerous practitioners and stakeholders.

Here, you will find the latest research, guidance, and tools relating to application of the mitigation hierarchy and ecological compensation, and a community of practice that is actively engaged in applying and improving the mainstreaming of biodiversity into development plans, programs and projects.

"Our goal is to act as a forum for the sharing of knowledge and experiences, and the generation of ideas around how we can continually refine and enhance our ability to balance development with good outcomes for people and the planet."

Local conditions and policy design determine whether ecological compensation can achieve No Net Loss goals


Local conditions and policy design determine whether ecological compensation can achieve No Net Loss goals

Many nations use ecological compensation policies to address negative impacts of development projects and achieve No Net Loss (NNL) of biodiversity and ecosystem services. Yet, failures are widely reported. We use spatial simulation models to quantify potential net impacts of alternative compensation policies on biodiversity (indicated by native vegetation) and two ecosystem services (carbon storage, sediment retention) across four case studies (in Australia, Brazil, Indonesia, Mozambique). No policy achieves NNL of biodiversity in any case study...
