Current projects

Mémento du Forestier

The Mémento du Forestier is a reference work for tropical forest management. The third, most recent edition was published in 1989. HAFL is represented on the committee – under the leadership of CIRAD and QUAE – for the planned new edition. The fourth edition includes new insights and important concepts for the management of tropical forests. One of HAFL’s responsibilities is the writing of a chapter on climate change.

Urban Green & Climate Bern

Trees in the city of Bern are facing new challenges as a result of climate change. HAFL is conducting a pilot study to investigate the significance of ecosystem services and the vulnerability of the urban tree population in view of climate changes. Using applied research, climate models and GIS, HAFL is developing principles and guidelines for appropriate tree management in urban areas.

Environment and Security in West Africa

Conflict over scarce resources and unclear ownership structures are significant contributing factors in deforestation and forest degradation. HAFL’s interactive on-line mapping tool enables spatial information about natural resources and conflicts to be visualised. Users can enter their land-use interests directly onto the map. This tool was first used in a case study in Côte d'Ivoire.

REDDES: Preparation of REDD+ Pilots in Ghana

REDD+ is a strategy both to reduce CO2 emissions from deforestation and forest degradation and to fix carbon in suitable land-use systems. In close cooperation with the Forestry Research Institute of Ghana, HAFL is supporting the preparation of various regional REDD+ pilot projects with the aim of improving the livelihoods of Ghanaian smallholders.

REDD+ and FOEN Monitoring 

Forest inventories are an important instrument for sustainable timber production and for monitoring biodiversity and carbon sequestration in forests under international agreements and conventions (CBD, UNFCCC, REDD+). The Swiss Federal Office for the Environment (FOEN) has mandated HAFL to support the establishment of a regional forest monitoring system in West Africa. This project is also contributing to regional and international exchange on the subjects of forest use and monitoring.
