Project Subject

The negative consequences of the acute global crises of this time, climate change and loss of biodiversity, are also becoming increasingly apparent in Tanzania. Although conditions in large parts of the East African country are still favorable for productive agriculture, and there are still relatively large areas of intact ecosystems, including forests, tree, bush and grass savannahs, wetlands and bodies of water, Tanzania is one of the world's 36 biodiversity hotspots. Even two of the world's 36 biodiversity hotspots are found in Tanzania (Eastern Afromontane & Coastal Forests of Eastern Africa). However, land use intensity and land requirements are increasing at an ever-increasing rate in both urban and rural areas. For example, Tanzania ranks 25th in the world with a total loss of tree cover of 28.6 km² from 2001 to 2021. At the same time, as a result of climate change, the region is experiencing a reduction in water availability (rising temperatures accompanied by little change in annual rainfall), reduced predictability of seasonal changes between rainy and dry seasons, and an accumulation of extreme weather events (droughts, heavy rains, storms). All of this leads to ecosystem degradation, loss of biodiversity, and a decline in essential ecosystem services. As a consequence, significant impacts on agricultural production as well as other land use activities to secure livelihoods in the affected regions are to be expected.

The new project PRO-NDC-ACT ("Promotion of Participatory Processes for the Implementation of NDC through Nature-Based Solutions in Urban, Rural and Coastal Landscapes of Tanzania") of the Chair of Ecological Economics aims at developing and implementing nature-based solutions with the participation of the affected village communities to address the problems mentioned above. In concrete terms, it is planned to reforest deforested areas and to develop them in an ecologically sustainable manner, taking into account the utilization needs of the local population. In this way, greenhouse gas emissions are to be reduced, the risks resulting from climate change minimized and ecosystem services promoted.

Project Implementation

Bernd Siebenhüner and Maximilian Petzold from the Chair of Ecological Economics at the University of Oldenburg are responsible for the coordination and technical management of the project. The implementation on site is carried out by the Tanzanian project partners of the non-governmental organization "Climate Action Network Tanzania". In addition, Prof. Dr. Pius Yanda from the University of Dar es Salaam and Prof. Dr. Michael Kleyer from the AG Landscape Ecology of the University of Oldenburg support the project with their expertise.

In a first step, socio-economic and ecological background information will be collected from three possible project regions: Bagamoyo (Coast Region), Pangani (Tanga Region) and Southern Pare Mountains (Kilimanjaro Region). The above regions are within the natural ranges of mangrove forests (Pangani), East African coastal forests (Bagamoyo & Pangani), and Eastern Arc montane forests (Southern Pare Mountains).

During an initial field trip to the three potential project regions, scheduled for late September / early October 2022, the project team will identify communities that have been affected by deforestation but still have natural forests in their watersheds and show interest in forest restoration and sustainable forest management.

Reforestation initiatives will then be established in the selected communities. To this end, village communities will be closely involved in individual project activities. These include:

(1) Selection of suitable afforestation areas

(2) Definition of concrete development goals for the afforestation areas

(3) Targeted selection of tree species to be planted, taking into account local soil, water and climate conditions (predicted state as a result of climate change), local knowledge and the intended use or desired state of development

(4) Tree plantings; and

(5) Ecologically sustainable management of reforestation areas.

Through public meetings, consultations and workshops, the project partners aim to involve local communities in all activities from the outset, ensuring that the reforestation projects are supported by local initiatives beyond the end of the project period and thus remain effective.

3 years (until 30.06.2025)


The project is funded by the International Climate Protection Initiative of the German Federal Ministry of Economics and Climate Protection (BMWK) to the tune of around 520,000 euros.


The participation of local people is at the heart of the project. The main partner of the University of Oldenburg is the Tanzanian non-governmental organization "Climate Action Network Tanzania".
