Climate change poses a significant global environmental challenge, with CO2 levels projected to escalate dramatically by 2100. Forests play a pivotal role in the carbon cycle, offering substantial mitigation potential for greenhouse gas emissions. This document discusses various mitigation options in the forest sector, such as carbon conservation, afforestation, and sustainable logging practices, while highlighting the need for effective policies and community engagement to overcome existing barriers and enhance forest management and biodiversity.

Global Climate Change • It is an important global environmental problem • CO2 concentration has increased from 280 ppmv (pre-ind rev-1750) to 368 ppmv in 2000 • Projected to reach 540-970 ppmv by 2100 • Global mean temp is projected to increase by 1.4 to 5.8 deg C by 2100 • Projected climate change is likely to have adverse impacts on natural ecosystems such as forests and human systems such as food production • Thus, climate change issue has attracted global attention
Forests & Climate Change • Forests play a critical role in global carbon cycle • Forests contribute about 20% of global CO2 emissions • Forest ecosystems are vulnerable to projected climate change • Likely to have adverse impacts on forest biodiversity and biomass production • Thus need to assess impacts and develop adaptation strategies • Forests provide a large mitigation opportunity to stabilize GHG concentration in the atmosphere along with significant co-benefits • Mitigation through forest sector has been a contentious issue in climate negotiations
Mitigation Options Mitigation: Includes all activities aimed at reducing GHG emissions and/or removal of CO2 from atmosphere, to stabilize CO2 concentration in the atmosphere • Mitigation in the forest sector; includes carbon sink conservation, C sink expansion & fossil fuel substitution by bioenergy I. Forest Carbon Conservation Management Measures • Banning deforestation or forest conversion to non-forest uses • Formation of protected areas, conversion of forests to national parks and sanctuaries • Adoption of sustainable logging practices • Adoption of forest fire control techniques • Implementation of fuelwood conservation and substitution • Fuelwood efficient stoves, efficient charcoal kilns and biogas • Recycling of forest products
Mitigation Options… II. Carbon Storage Management • Natural regeneration • Reforestation in degraded forest lands • Afforestation in non-forest lands • Carbon pools in durable wood products III. Substitution Management • Bioenergy substituting fossil fuel electricity • Sustainable wood products substituting fossil fuel based building materials (cement, steel etc.)
Area under forests: Forest Conversion/loss: Afforestation Area brought under JFM (largely regeneration): Wasteland estimates: Potential for agroforestry: (Cultivable waste to long fallow) 63.7 Mha About 200,000 ha 1.4 Mha annually 1.4 Mha annually 66 to > 100 Mha 20 Mha Indian Situation
Indian Situation… • Effective Forest Conservation Act and other legislations • Biomass demands growing leading to; • Shortages of fuelwood, pulp, timber • Large imports • Increased livestock grazing pressure on forestlands • Large external funding to afforestation activities • State support to afforestation is declining in many states
Why Explore Mitigation Opportunity in Forest Sector? • Need to conserve forests and reduce pressure on forests • For non-GHG related reasons such as • biodiversity, watershed, livelihoods • Need to afforest/reforest degraded lands to prevent land degradation • Need to grow biomass to meet growing demand • Need to develop community institutions and enhance capacity to protect and manage forests • Need to work towards stabilization of GHG concentration in the atmosphere • CURRENT EFFORTS INADEQUATE • TECHNICAL, INSTITUTIONAL, FINANCIAL BARRIERS
Advantages of Implementing Forest Mitigation Projects; Afforestation and Reforestation • Introduce innovative technical interventions into A&R programs to • Increase biomass productivity • Conserve biodiversity • Enhance the rate of spread of A&R • Reclaim degraded lands • Build institutions at village to forest division to state level • Adopt innovative institutional interventions to strengthen community institutions • Enhance financial flows to communities
Potential Contentious Issues • Losing low-cost mitigation opportunities? • Global demands for forest carbon credits (CERs/RMUs) limited • Insignificant loss of carbon credit potential • Communities may lose access to land & biomass • Project should be fully compatible with JFM/other regulations • Community needs can be built in to project • Non-permanence, leakage and uncertainty in measurements of carbon stock changes • Techniques, accounting rules and models available • SBSTA & IPCC are developing guidelines
Mitigation Potential • Estimate technical, economic and market potential • Demonstrate environmental additionality • Estimating the carbon stock changes in baseline and mitigation scenario • Estimating incremental or additional C seq. • Need for policies, programs and measures to overcome barriers to A&R and enhance stakeholder involvement • Need for additional investment to overcome the barriers • Need for methods, techniques and models to address issues of non-permanence, leakage, uncertainty etc.
Mitigation Potential Through a Sustainable Forest Management Approach for India • Potential Scenarios • Technical potential scenario • Sustainable forestry scenario • Commercial forestry scenario • Potential Mitigation Activities • Afforestation – short rotation • Afforestation – long rotation • Forest regeneration (reforestation) • Forest Protection • Bioenergy
Baseline Scenario • Current rate of forest loss projected to continue • Rates of afforestation projected to decline • Area under crops stabilized (at ~ 150 Mha) • Current (10th plan) rate of investment projected to continue • Biomass demands are not systematically addressed in afforestation programs
Sustainable Forestry Scenario • Estimate fuelwood, industrial wood and sawn wood demands for 2015 • Assess land use pattern and surplus land available for forestry activities • Identify forestry activities for meeting biomass demands eg. Short-rotation plantation for ind.wood • Allocate forestry activities to compatible land categories; SR-plantations for private lands • Meet current biomass demands (for 2000) from baseline activities; existing forests, plantations, farms • Meet incremental (2015 minus 2000) biomass demands from proposed forestry activities
Method of Estimation of Carbon Benefits & Costs • COMAP model developed by F-7 (Tropical Forest -7) Network • Inputs; Baseline & project scenario • Area afforested-yearly, Soil C, Biomass growth rate, Rotation period, Life of product, investment cost, annual cost, monitoring cost, value of products (timber, fuelwood, NTFPs) • Outputs; Baseline and Mitigation scenario • Annual and cumulative carbon stock changes (tC/ha) • Incremental carbon stock • Total C stock per ha • Cost-Effectiveness; • Investment cost; Rs/tC or Rs/ha • Life cycle cost; Rs/tC or Rs/ha • Net present value of returns; Rs/tC
Data, Methods, Models are critical- Baseline & Project Activities • Monitoring & estimating • AGB stock, annual AGB growth rate • Soil carbon stock, annual / periodic changes • Developing ratio of AGB to BGB • Monitoring extraction rates and effects on carbon stock • Monitoring area changes, crown cover changes and linking to biomass stock changes • Estimating production of wood and NTFPs & values • Models for projecting biomass and soil carbon stock • Models & methods for incorporating barriers for estimating mitigation potential • Models for estimating costs and benefits
Addressing Contentious IssuesGuidelines, Methods, Models • NON-PERMANENCE/REVERSIBILITY OF CARBON SEQUESTERED;Temporary nature of CO2 removal by sinks from LUCF activities • Estimating C stocks annually • LEAKAGE;Net change of anthropogenic emissions by sources of GHGs and removal by sinks, which occurs outside the project boundary, and which is measurable and attributable to the CDM project activity • Estimating C stock changes within & outside project boundary • ADDITIONALITY; A project activity is additional if anthropogenic GHG emissions are reduced below those that would have occurred in the absence of the project activity [OR ] CO2 removal by sinks that are higher than that would have occurred in the absence of a project activity • - Estimate C-stock changes under baseline and mitigation Sce
