On the 11th of December 2015, in the Forest Park "Hum" on the territory of Novo Sarajevo Municipality, a forestation action took place. The Action was realised within the project "Environmentally Responsible Individual - the Cornerstone of Sustainable Development", implemented within the UNDP's Project „Reinforcement of Local Democracy IV – LOD IV“, financed by the European Union from the Instrument for Pre-Accession Assistance (IPA) in the amount of EUR 2 million. The action involved pupils from Novo Sarajevo elementary schools, who were joined by the employees of the company “HOLDINA”, representatives of Novo Sarajevo Municipality, and Local Community Office Pofalići II. Together, they planted over 400 seedlings of ash tree, catalpa, walnut tree, spruce and cupressus trees. The objective of this action is to raise awareness of the importance of forests and their various functions in protection of environment, with special emphasis on production of oxygen and purification of atmosphere. This project is implemented by the Centre for Environmentally Sustainable Development – CESD from Sarajevo, and its objective is to contribute to the improvement of the state of environment of Novo Sarajevo Municipality, through education and environmental awareness raising activities.
