Biodiversity and climate change
- Avenues for adaptations

Definition of Biodiversity
CBD Article 2
‘The variability among living organisms and the ecological complexes of which they are part, including the diversity within species, between species and of ecosystems.’

Ecosystems diversity
Species & variations within species
Role of biodiversity – some examples
High quality forest water feeds 103 main rivers - Millions of people depend
25% tourists visit wild life areas 163,000
livelihoods =
Our energy basket
43.5% Biomass5.7% Hydro power 1400 medicinal
plants
Food fish - 70% of our animal protein supply263,000 livelihoods
Agricultural biodiversity – 33% of our labor force
Global economic value of pollination insects 217 Billion USD
Key points -Sri Lanka is among 34 global biodiversity hot spots-Richness- highest per unit area in Asia-Biodiversity Governance - 30 state institutions90 laws (direct & indirect) 40 MEAs (25 conventions plus protocols, treaties, agreements & amendments)Many policies/strategies/action plans
How biodiversity get impacted by CC?
-Too much water where we don't need-Too little water where we need more-Too much water when we don't need -Too little water when we need more-Too hot everywhere-Salinity???
ISSUESISSUES OF CC
Forest die back
Forest fires
Illigal timber fellings
Invasive plants
Human elephant conflict
(You name it !!!!)
Sea level rise
How can we adapt?
- Identify most vulnerable biodiversity assets- Identify adaptation thrust areas - Plan for short & long term changes- Allocate resources accordingly - Act on ecosystem basis
Basic ideas of Hopkin’s Principles of adapting Biodiversity under CC
- Conserve what you already have- Reduce non-climatic pressures- Develop resilient & diverse ecosystems- Enhance healthy landscape linkages - Make informed decisions- Harmonize adaptation with mitigation & human dimension
Awareness & Capacity Building
Restore degraded areas

Control forest fire
Focus on sustainable timber use, not in destructive manner
Plant trees in available spaces Accommodate some animals in urban landscape
Protect Protect Riverine Riverine forestsforests

Tree dominated home gardens
Use less fire wood
Organic Home garden – reduce food miles, high productivity per ha & no chemical pollution
Go for intensive agriculture
Low productive EXTENSIVE agriculture
