Can we manage for timber and biodiversity in the Congo Basin?

Workshop “Managing wild species and systems for food security”

Robert Nasi

World Conservation Congress, Jeju, 08/09/2012

Selective logging in the congo basin
Selective logging in the Congo Basin Basin?

  • Timber remains the sole managed commodity

  • Highly selective, few individuals (less than 2) of few commercial species (less than 5) represent more than 75% of the volume harvested (less than 10m3/ha)

  • Rotation cycles of about 25-30 years; Minimum cutting diameter rules; No post-harvest silviculture

  • The area under proper management and certification is increasing:

Harvesting intensity and residual stands

Nasi & Forni, 2006

Number of trees harvested/ha

Impact of certification on harvest intensity Basin?

Certified concessions have a significantly reduced harvesting intensity

Cerutti et al. 2011

Pro-biodiversity activities in logging concessions Basin?

Only certified concessions show significant activities in favor of biodiversity

Basic intentions, Limited results

Activities limited to legal requirement

Limited results

No methods

No capacities

Limited activities

Motivated CEO and some staff

Long term efforts

Effective fieldactivities

Billand et al. 2009

Bushmeat hunting in congo basin
Bushmeat hunting in Congo Basin Basin?

Estimates of the value of the bushmeat trade range from US$42 to US$205 million per year in West-Central Africa.

Current harvest in Central Africa alone may well be in excess of 5 million tons annually, could represent more than 20 million ha deforested for pasture!

30 to 80% of the protein intake of many rural populations

Barriers and solutions Basin?

(TRAFFIC workshop, Libreville, June 2010)

Beyond boundaries landscape scale considerations
Beyond boundaries: Basin?Landscape scale considerations

Why a landscape approach? Basin?

  • High mobility of wildlife (migration, dispersal, extensive territories…)

  • Conserving Protected areas alone, will not be enough to conserve large sized/highly mobile species with huge ranges (e.g. Elephants) or locally rare plant species

  • The contribution of production forests to biodiversity conservation is increasingly recognized (e.g. North Congo where gorilla densities are higher in logging concessions than in the neighbouring NP)

Protected areas and logging concessions : surprisingly close neighbors

OFAC, State of Forest 2008

National Parks close neighbors

Logging Concessions

Hunting areas

Parks, Concessions, Hunting areas : where are flagship species ?

Some surprising assessments

Number of ape nests/km2

OFAC, State of Forest 2008

Integrated production conservation territory
Integrated production / conservation territory close neighbors

Combine (at least) two major land use types (e.g. a logging concession and a protected area)

with community-based managed areas

in one land-use management unit that could become an integrated production/conservation landscape

Billand & Nasi 2006

Urban close neighbors, social space

Environmental services

Local incomes

Taxes, fiscal revenues

Sustain rural population










Mixed area : protected area and conservation enterprise







Billand & Nasi 2006

Basic rules
Basic rules close neighbors

Realize the economic potential of the conservation side

Manage informal sectors like hunting, fishing or NTFP extraction for local livelihoods

Use part of the income generated by the industrial production side for the conservation area for reciprocal benefits

Foster certification (not limited to timber considerations)

Enabling conditions
Enabling conditions close neighbors

Starting funds are needed to cover initial transaction costs

The willingness of the production sector to engage into certification or other biodiversity friendly practices

The willingness of the conservation community to collaborate, share experiences and support the private sector in integrating conservation concerns in management practices

A proactive political support (creating specific land-use units with specific instances for decision making) or, at least, neutral (no undue interference from the State).

The Congo Basin has identified 12 Landscapes designed for shared production and conservation management of forests

Actors (public, private sectors) are aware about the necessity to improve collaboration for concerted or integrated management

But experiences at field level remain limited

To conclude
To conclude… shared production and conservation management of forests

We believe that management for both timber and biodiversity is possible in the Congo but it requires new thinking in terms of land-use types and stronger private–public partnerships associating production and conservation parts of the landscape and a renewed long-term support from the international donor
