Wood as energetic biomass threats and opportunities

1
Wood as energetic biomass threats and
opportunities

• Zdenek Potulka
• Hnutí DUHA FoE CR

2
What are the threats?

• 1. Forest over cropping using all the biomass
  causing erosion, nutrient imbalance, decrease of
  biodiversity
• 2. Establishing monocultures and plantations of
  non native species

3
Addressing threats of 1.

• Strict forest categorization (specific zones)
  using multi variant analysis and spatial planning
  methods.
• Addressed variables soil erosion, run off, water
  quality, slope stabilisation, soil nutrients,
  biodiversity, recreation

4
Adressing erosion, water retention and water
quality - protective forests along streams
5
Adressing threats of 2.

• Based on the previous zonation of forest, there
  should be worked out areas
• 1. suitable for plantations (energy first),
• 2. suitable for biodiversity rich energetic woods
  (balanced wood production, biodiversity,
  erosion-flood control)?
• 3. areas with close to the nature forests without
  energetic use (soil, biodiversity protection
  first, wood for constuction, fuel second)?
• 4. no-go zones with ancient forests (soil, water
  protection, biodiversity, carbon sequestration).

6
What are the opportunities?

• Landscape restoration, implementing adaptation
  measures
• Developing carbon credit systém and offsetting
  schemes for landscape and ecosystems

• "Our work suggests that the impacts of
  human-caused landcover changes on climate are at
  least as important, and quite possibly more
  important than those of carbon dioxide," said
  Roger Pielke, Sr., an atmospheric scientist at
  Colorado State University, Fort Collins, Colo.,

.

• "Through landcover changes over the last 300
  years, we may have already altered the climate
  more than would occur associated with the
  radiative effect of a doubling of carbon dioxide."

• Forests and peatlands have a unique role to play
  in the battle against climate change. Living
  forests and peatlands can sequester carbon
  emissions, while dying ones release previously
  stored carbon.
• Every year the annihilation of these two habitats
  generates more greenhouse gas than every car,
  truck, train and plane on earth. This is roughly
  the same as the amount of CO2 that is emitted by
  the United States or China each year.

13

• In the UK alone, biofuel subsidies cost 550
  million annually. In 2005, a similar investment
  in preventing forest and peatland deterioration
  could have offset the equivalent of up to 37 of
  all UK CO2 emissions. Yet current government
  policy places no value on restoring forests and
  peatlands.

• Supporting EU policies
• Water framework directive water quality
• Flood directive water quantity
• Natura 2000, Convention on biological diversity
• Climate adaptation and mitigation policies
  carbon sequestration, energetic biomas,
  microclimate

15
Basic variables multicriteria analysis

• Life cycle analysis
• Cost benefit analysis
• Biodiversity, Natura 2000 impact assesment
• Carbon sequestration, climate change adaptation
  and mitigation
• Water retention, flood and drought prevention,
  erosion protection

16
Win-win systems

• 1. river-floodplain restoration, coppice, coppice
  with standards
• 2. No intervention forests (carbon sinkm erosion
  prevention...)?

17

• 3.Unstable plantations diversification
• 4. coppice with standards (coppice) on deep
  fertile soils

18

• 6. High forest on slopes
• 7. Untouched areas (carbon sink)?

19
Areas suitable for coppice (willow plantations)?

Achieving targets-assumptions

• Adaptation measures closely linked to flood
  protection and water quality
• Offsetting schemes aimed at carbon sequestration
• Offsetting schemes aimed at sustainable biomass
  production
• Biodiversity is a landmark for sustainable
  production systems(site specificity means low
  energetic inputs and maximal net production)?

41
Support needed

• Framework policies supporting carbon
  sequestration and landscape restoration schemes,
  linked to water and biodiversity policies
