CIMO - Centro de Investigação de Montanha (Mountain Research Centre) - is a multidisciplinary research centre focused on mountain issues. It was founded in 2002 within the School of Agriculture of the Polytechnic Institute of Bragança (Instituto Politécnico de Bragança) and since 2003 it is part of the national research network funded by the Portuguese Science and Technology Foundation (FCT).

CIMO was established to study and valorise mountain natural resources, forest and agriculture ecosystems, and local products in order to develop systems economically, socially and environmentally sustainable. CIMO is socially committed at enhancing opportunities and income for and in mountain areas.

The centre has currently 78 members, 51 of which with a PhD degree, specialists in a wide range of scientific fields including agronomy, animal science, forest science, ecology, biology, economy, sociology, chemistry, biochemistry, environmental sciences, and computer science. This diversity of backgrounds and expertise allows the centre to be remarkably multidisciplinary which suits CIMO’s main objects of study: complex physical-biological-human mountain systems.

CIMO is organized in three research groups: Marginal Land Ecosystem Services (MLES), Mountain Farming Systems (MFS), and Food Safety and Technology (FST). These groups, covering the broad range of research fields in mountain areas, correspond to the way mountain landscapes and activities are structured in Portugal.

CIMO is a member of EuroMontana, the European association for co-operation and development of mountain territories. CIMO is a parter of the International Year of Biodiversity 2010.
