• Although policies are developed at the national level, losses and damages are ultimately incurred at the local level.
• Considering loss and damage is an issue affecting local communities, it is important that the measures used to the address future impacts of climate change are targeted to those in need
• Farmers in disaster prone areas face incremental risks as the global temperature rises and the frequency and severity of disasters increase
• Communities adopting coping measures such as looking for additional income or selling assets in order to buy food.
• Loss and damage is undermining food and livelihood security, social cohesion, culture and identity
Impacts of Loss and Damage at State Level
Conserving Now, Preserving Future
Govt. of Bihar
• Enhance the understanding of how loss and damage associated with the adverse effects of climate change affect particularly for vulnerable communities
• Policymakers will need to explore, develop and implement comprehensive risk management frameworks that include risk reduction, risk transfer such as insurance, risk retention such as contingency funds and social safety nets.
• Enhancing data on and knowledge of the risks of slow onset events and their impacts, and identify ways forward on approaches to address slow onset events associated with the adverse effects of climate change
• Building capacity of institutions to ensure that local households and communities can participate in the design and implementation of policies and programs
• Develop and implement financial instruments and tools that address the risks of loss and damage associated with the adverse effects of climate change

Conserving Now, Preserving Future
Forests in Bihar• Total Geographical Area: 94163 sq. km.
• Forest Area : 6845 sq. km. (7.23%)
• Degradation due to anthropogenic pressure.
• Degradation of ecological health on all fronts.
• Richness of vegetable cover, succession status, proneness to erosion, moistureregime, surface water retention, ground water recharge.
• Floral & Faunal bio-diversity, soil health and potential productivity, spread ofinvasive species.

Climate change• A confirmed phenomenological observation.
• Increase in erratic pattern of precipitation.
• Changed rainfall pattern: Reduced number of rainy days.
• Copious of peaked downpours on fewer days.
• Long spell of dry days during monsoon.
• Some areas are most affected: Some forest area are adaptive to climate change, some are not
• It causes:
– More erosion and reduce water & moisture retention
– Impact physico-chemical and biological system over a range of realms and scales- Soil moisture, soil microfauna, mychorrhizal associations, seeding, germination, water and food availability for small and big fauna

• Only 2 districts having forestareas are less vulnerable:Nalanda (Low) andJehanabad (Average).
• Among forest districts-Nalanda is least vulnerableand Kaimur is highlyvulnerable.
• It shows that districtshaving forest areas arehighly vulnerable, whichrequires interventions.

Observation• Nalanda, Munger and Banka forest divisions low IVI score of large no. of species in the
community show that these areas are rich in diverse vegetation.
• Department has started soil and moisture conservation and Regeneration of DegradedForests activities in these areas from 2012-2013.
• Gaya, Kaimur and Aurangabad forest divisions are not so rich in vegetation as reflectedin IVI.
• A comprehensive plan has been prepared for these areas under Agriculture Road Map2017-2022.
• Various biodiversity indices calculated to show impact of interventions.

Response• Eco-system approach: Response to climate change.
• Watershed development: Micro watersheds have been treated with graded
appropriate type of structures ranging from check dams, silt detention dams,
water harvesting bunds and ponds in 11 Forest Divisions.

Forest Ecosystem in Bihar: Qualitative & Quantities study by FRI
Biodiversity & Sustainability
Sustainability:
•Ability to maintain Ecological process over long periods of time.
•Maintain structure and function of ecosystem
Biodiversity:
• Richness and variety of life- of genes, species and ecosystem
• Higher/more biodiversity = more sustainable
• Lower/less biodiversity = less sustainable
• High biodiversity in an ecosystem means that there is a great variety of genes
and species in that ecosystem.

• Shannon-Wiener Index (Shannon & Wiener, 1963)
H= - ∑ pi ln pi
Where pi is (Ni/N) , Ni = Number of individuals of species i and N= Total number of individuals of all the species.
• Concentration of dominance (cd) = Simpson Index (Simpson, 1949)
Cd = ∑ (pi)2
• Pielou's Evenness Index (Pielou, 1966) :
J = H'/ln(S)
where H’ is Shannon Weiner diversity and S is the total number of species

Outcome
• Transformational impacts- substantive implications for both the adaptive and
mitigation aspects of climate change
• Improving the moisture regime, water security and hydrological characteristics
and soil and vegetation system, incidence of forest fire. These treated watersheds
are leading the path-breaking and turnaround micro-biomes that adds to
resilience and adaptation capabilities of landscape.
