Starting Point
The technical, policy, and research discussion on the charcoal sector in Sub-Saharan Africa is commonly dominated by the following:
1. … unreliable data and information.
2. … antiquated contextualization.
3. … technical misconceptions & shortcomings.
4. … unclear definitions & tendency for miscommunication.
5. … well-embedded stereotypes.
6. … perpetuating stigmatization.
7. … regressive policy approach.
8. … unrealistic desires and objectives.
9. … wisdom from the past continues to serve as the fountain of knowledge for future solutions
Consequences
1. Wood energy in SSA is still approached as a household energy use issue, not as a commercial, nor industrial use
2. (Over-)emphasis on the problems, neglect of opportunities
3. It is good for some, bad for others
4. Neglect of economic context Africa has and continues to change dramatically
5. Rural and urban aspects of wood energy use often mingled together
Definitions (1)
The use of charcoal is generally categorized as being a “traditional” use of biomass
energy…
Definition of “traditional” biomass energy (use):
WEO 2010: Consumption in the residential sector in developing countries and refers to the often
unsustainable use of wood, charcoal, agricultural residues and animal dung for cooking and
heating (IEA 2010a).
Renewable Energy Market Report (IEA 2014c): Traditional biomass use refers to the use of
fuelwood, animal dung and agricultural residues in simple stoves with very low combustion
efficiencies. Traditional biomass use is estimated – in line with the methodology used in the IEA
WEO 2010 – as the use of solid biomass in the residential sector of non-OECD countries,
excluding countries in non-OECD Europe and Eurasia.
WEO 2014 Special Report on Africa: Traditional use of solid biomass refers to basic technologies
used to cook or heat with solid biomass, such as a three-stone fire, often with no or poor operating
chimneys. Modern use of solid biomass refers to improved cookstoves using solid biomass and
modern technologies processed biomass such as pellets.
WEO 2014: Traditional use of solid biomass as the use of solid biomass with basic technologies
such as a three-stone fire, often with no or poorly operating chimneys.
Definitions (2)
REN21 (2014) defines traditional biomass as solid biomass, including gathered fuel wood, charcoal,
agricultural and forest residues, and animal dung, that is usually produced unsustainably and typically
used in rural areas of developing countries by combustion in polluting and inefficient cookstoves,
furnaces, or open fires to provide heat for cooking, comfort, and small-scale agricultural and industrial
processing.
IRENA (2012): Traditional biomass use as the use of wood, charcoal, agricultural residues and animal dung for
cooking and heating in the residential sector. It tends to have very low conversion efficiency (10% to 20%)
and often relies on unsustainable biomass supply” (from IEA 2012).
IRENA REmap (2014): The estimate of traditional biomass use in 2010 follows the IEA definition, which
assumes that all biomass use in the building sectors outside countries of the OECD is traditional,
unless a REmap country provided a more detailed breakdown which allowed for more comprehensive
reporting.
Modern Biomass Energy:
(REN21, 2014): Energy derived from combustion of solid, liquid, and gaseous biomass fuels in efficient small
domestic appliances to large-scale industrial conversion plants for modern applications of space heating,
electricity generation, combined heat and power, and transport.
WEO 2014 methodology for Energy Access Analysis: A household having reliable and affordable access to
clean cooking facilities and to a minimum level of electricity consumption which is increasing over time.
This definition includes provision of cooking facilities which can be used without harm to the health of those in
the household and which are more environmentally sustainable and energy efficient than the average
solid biomass cookstove currently used in developing countries.

Selected examples of analytical work:
Urbanization – Driver of Charcoal Use in Africa
Urbanization in Africa is accelerating:
Between 2000 – 2030 population in SSA is expected to double
By 2030 50% of Africans will live in cities
52 cities with ≥1 million people (same as Europe and more than North America)
Population growth & migration to cities
Shift of fuels: fuelwood charcoal
Rapid urbanization is a global trend:
Since 2008, 50% of the world’s population lives in cities
By 2050 this number will increase to 5
billion
Lagos is growing at a rate of about 6% per
year. Dar-es-Salaam at about 4.3% per year.
1% increase in urbanization 14%
increase in charcoal consumption.
Shift from fuelwood to charcoal can reduce IAP
by 90%

We sure have lost closed, natural forests, but… is it because of woodfuel use?
What does the loss of dense natural forest mean for woodfuels?
Charcoal and Forest Management
Attributability (multiple drivers of deforestation and forest degradation)
Deforestation => permanent land-use change
Charcoal production as “side-effect” of agricultural development, but not principle cause
Forest cover ≠ wood supply
Unreliable supply and demand data modeling?
A never materializing “woodfuel crisis”
Wood energy provides economic benefit => incentive to manage forests, not to cut down
“Deforestation / forest degradation ” versus “forest management regimes”
Charcoal use commonly associated with deforestation and forest degradation.
Issues for considerations:
Deforestation or Forest Management?
Original satellite image Complete classification of land
use classes for the same area
9 different land-uses (excl. water), 8 with variations of woody biomass
1 “very dense natural forest”, 6 variations of “degradation”
2 variations of deforestation conversion to agriculture
More Examples
We need:
Accurate growth and yield data for all forest types
We need to measure all woody biomass (outside forests AND <10cm dbh)
Deforestation / Degradation versus Forest Management
Deforestation Forest degradation Closed forest
The forest frontier is history (with a few exceptions) “Mosaic” forests
Forest management in a productive landscape:
Some call it “deforestation” – others “forest management systems”
For woodfuels, short-rotation is an optimal, high-yield targeted management systems (often through coppicing)
Often trees have dbh of 10cm or less not accounted for in forest inventory
Forest (Cover) versus Tree (Cover) – The Case of Haiti
Conventional anecdote: Only 2% of Haiti’s original forest cover remains
Then Churches et al. 2014 came and did the following analysis:
More Examples
Rwanda: Increase in satellite image resolution changed woodfuel supply-demand deficit modeling from 61% to 21% between 2006 and 2009 (Drigo et al. 2013)
Fraction Non-Renewable Biomass (fNRB) assessments:
Early assessments applying the criteria as defined by the CDM indicated extremely high fNRB, commonly ranging above 80% and 90% for most countries.
The most recent global assessment of fNRB commissioned by the Global Alliance for Clean Cookstoves, resulted in significantly lower estimates of NRB fractions now averaging 27%-34% (Bailis et al 2015).
Consequence:
Forest management in the landscape requires adapting data capture, analysis, and information management
Hypothesis:
If all trees were to be counted, may be there is no woodfuel deficit after all?
Probably not…
No doubt we have lost a lot of contiguous forest cover and forests have become more fragmented, but not because of woodfuel use
If so, it should have long turned into a supply “crisis”
Forest loss and fragmentation of forest ecosystems due to land-use change triggered by agriculture production extension (incl. livestock) and settlement extension
Some areas with highest “woodfuel crisis” projections have more people and more forest cover than before
Demand for wood products due to urbanization is exponential impacts should be much higher
Continued limited understanding of causes and drivers of land-use change (correlation ≠ causality)
But we don’t know !!!
To demystify the wood energy sector, debunk common misconceptions (or confirm them), and to make informed policy and investment decisions…
…we need data, data, data !!! (That nobody has)
Is there a Woodfuel Crisis (once again)?
Well…
While these guys do move from A to B…
… is it sustainable (economically, socially, and environmentally)?
Charcoal consumption will grow or remain at very high levels
“Alternative” sources of energy will increase in price
Accelerated electrification is needed, but will not replace charcoal use
Need to cut energy subsidies and to achieve cost recovery will continue
Climate change calls for enhanced forest management: mitigation and adaptation
$$$ needed for sustainable forest management
Why still urgency in Charcoal Sector Reforms?
Challenges to Sector Reforms
There are no real technical challenges!
Lack of leadership
Vested interests & political commitment
Governance
Forest rights & benefit sharing
Forest service delivery vs. command & control
Challenges to Charcoal Sector Reforms
What I did not talk about today
Macro- and microeconomics of wood energy
Political economy, policy framework, and reform
Jobs and livelihoods
Fossil fuel subsidies and wood energy
Wood energy, climate change, and Green Growth
Charcoal, biomass, and power production
Health, gender, and charcoal
Charcoal, wood energy trade and (household) wood energy use in developed countries
Charcoal trade as a source of conflict financing
Technical considerations and best practices
Modern & Holistic Approach
Woodfuels deserve to be treated as any other commodity:
• Unnecessary degree of reservation and discomfort – especially in developing country context
• In many countries realities have caught up with aspirations
• Modernize policy framework
• Facilitate supply chain management enhancements
• Catalyze private sector investments, but no crowding out
Let’s Learn from other Sectors
Comparing basic need challenges and responses in two related sectors:
Food Security (Biomass) Energy Security
Facilitate trade Impose bans
Provide extension service Implement command and control forest governance
Educate farmers Charge bribes
Award best practices Throw people into jail
Engage in research Still don’t have a clue
Provide seeds Buy law enforcement equipment
Decentralize responsibilities to the field
Recentralize control in capitals and line ministries
… to be continued
A simple “Road Map”
1. Filling knowledge gap
2. Enhance policy dialogue, capacity building, and policy reforms
3. Facilitating cross-sectoral collaboration
4. Mobilizing Investments
… the usual stuff…
Action items:
Put all natural forests under conservation
Focus on planted forest / restoration / reforestation, etc.
Create forest service, not police
Modernize governance framework, collect revenues and reinvest
Use REDD+ as seed funding, but not eternally
