3 Low Emission Land Use Planning (LELUP) Section 2. Assessment of Current and Historical Condition 2.2. Understanding Historical Land Use Change and Current Condition Regional Climate Change Curriculum Development

4 ENABLING ENVIRONMENT ASSESSMENT OF CURRENT CONDITION ANALYSIS OF FUTURE OPTIONS NEGOTIATING & PRIORITIZING IMPLEMENTA- TION PLAN MONITORING & EVALUATION Low Emission Land Use Planning 1.1. Regulatory Assessments 1.2. Stakeholder Engagement 1.3. Planning & Development Goals & Objectives 2.1. Environment, Social, & Economic Data Needs 2.2. Understanding Historic Land Use Change

5 At the end of this session, learners will be able to:  Determine drivers (or causes) of historical land use change and the ‘actors’ involved in these processes.  Evaluate process (spatial and non-spatial) to help quantify historical land use change.  Quantify the current resource condition from which to compare future change.

6  Session Introduction  Drivers of Change  Deforestation vs. Degradation  Direct vs. Indirect Drivers  Method for estimating change  Exercise  Example  Summary

7 Rules of the Game Time/Space Drivers of Change Goal / Objective NOW Past Trend / Current Condition BAU

8  Agricultural expansion  Timber production  Infrastructure development  Economic growth  Demographic changes  Governance  Technology  Environmental issues

9 Rate of agricultural expansion in Southeast Asia increased from 0.7% pa between 1997 and 2002 to 1.2% between 2002 and 2007 and 1.7% between 2007 and 2009

10 Resurgence after 2001

11 Road network expansion greatest in Viet Nam and Thailand

12  Economies growing rapidly and demands on forest resources will increase  Poverty and migration remain key issues

13 Southeast Asia population:  593 million in 2010 → 657 million in 2020 Rapid urbanization:  47% urban in 2010 → 54% in 2020

14 Corruption worsening except in Indonesia and Brunei Source: World Bank

15  Productivity enhancement  Processing technologies

16 Displacement of timber demand to other countries following logging bans and forest protection should be considered.

17 Deforestation  “The long-term or permanent conversion of land from forested to non-forested land”  Example where definition is for 20% forest cover Forest ≥ 20% Canopy 90% Canopy Non-Forest < 20% Canopy 10% Canopy Δ

18 Degradation  “Changes within the forest which negatively affect the structure or function of the stand or site, and thereby lower the capacity to supply products and/or services”.  Example where definition is for 20% forest cover Forest ≥ 20% Canopy 80% Canopy Forest Still ≥ 20% Canopy 50% Canopy Δ

22 Deforestation Data  Agriculture is the key driver of deforestation (about 80%)  Both commercial and subsistence  Food demand is projected to increase by 70% globally over the next 40 years

23  Drivers different for forest degradation  Primarily logging and fuel-wood charcoal  In subtropical Asia timber logging is key driver  In Africa it is wood for fuel Deforestation Data

26 Assessment of historical drivers of landscape change is essential:  Are drivers directly or indirectly causing the problem?  What is the scale at which the drivers operate?  What is the drivers trend or trajectory?  Do the drivers interact?  Who are the key actors or stakeholders involved with the identified driver; and

27 A very similar process can be used to identify historical and future threats (drivers) to key biodiversity assets. Direct Threats: Human activities: Unsustainable Timber Harvest Natural phenomena: Water availability limited in forest by city Natural phenomena whose impact is increased by other human activities Type conversion from Forest to scrubland and limited water

28 In small groups, each student is to carefully read the case study and then discuss within their group the following questions: 1. What are the direct and indirect drivers of deforestation and forest degradation and the relationship between the two? 2. What is the scale and historical trend for each of the drivers? 3. Who are the actors involved for each of the identified drivers? 4. By assessing historical drivers of landscape change, what information can this provide the Florestania REDD+ Task Force in predicting future landscape change? Each student group will be required to provide a brief report on their findings.

29 1. Prepare: Set time period for analysis. Ensure maps for individual date are consistent (definitions, classifications, sensors, etc). 2. Overlay: Use GIS or image processing software to overlay two land use maps from two different dates. Creates an attribute table where each polygon or pixel contains the recorded land use on both the 1 st and 2nd dates. 3. Simplify the attributes to a set of unique land use change transitions. 4. Create the land use change matrix:

30 The current land use planning goals in Lam Dong Province, Vietnam are: CategoryObjectiveIndicator EnvironmentalMaintain at least 61% forest cover by 2015 Percent forest cover Maintaining or improving ecological integrity 1) Ratio of natural forest to plantations 2) Species type diversity 3) Richness Reduce GHG emissions in the AFOLU sector by 20% by 2020. Tons CO 2 equivalents (tCO 2 e)/year EconomicIncrease annual GDP growth rate from 12-15% GDP growth rate GDP per capita will reach USD 2,300 by 2015 GDP per capita SocialPopulation growth reduced to 1.3% (2015) and 1.2% (2020) Population growth rate by urban and rural sectors No poor households by 2020General poverty rate by urban and rural sectors

43  Increased level of complexity will challenge land use planners and place additional pressures on land management agencies.  Accurate and consistent historical data is notoriously difficult to gather.  Connecting landscape data analysis and field level interpretation is a challenge.

44 There is now increased investments (REDD+) that are investing in quantifying drivers of change that can be used for LE-LUP
