Land Use and Emissions in South and Southeast Asia Objectives of the Meeting

Transcription

1 Land Use and Emissions in South and Southeast Asia Objectives of the Meeting Chris Justice Dept. of Geographical Sciences University of Maryland Krishna Vadrevu NASA/MSFC

2 Objectives of the Meeting 1 Increased participation of Vietnam in the regional South Asia/Southeast Asia Research Initiative (SARI) on Land Use Science (see Dr Vadrevu s presentation) Understand the pressing regional issues for Land Use Science

3 Some Examples of pressing Land Use issues for the Mekong Region Decreasing river flow (upstream use) Extreme climate events drought and flooding Salinity encroachment Declining crop production and rice quality Ground water withdrawal and wastewater pollution Agriculture/Aquaculture and nutrient/pesticide residue Mangrove forest loss

4 Objectives of the Meeting 2 Share knowledge and experience in the use of Earth Observations to study Land Cover and Land Use Change Understand which EO data are freely available and how to get hold of them Share experience on effective Land Management practices (particularly within the SARI Region) Share best practices on Land Use Emissions Estimation and Mitigation Strengthen international scientific cooperation on Land Use issues within the region and globally Seek out opportunities for research collaboration

5 Why Land Use? Land Use is integral to the livelihood and sustainable development of the countries of the region e.g. Critical to national food security Critical to good resource management Critical to viable conservation Critical to the distribution of wealth Critical to the culture of the majority of the people Land Use Science (monitoring, modeling and analysis) to inform Land Use Policy e.g. To address pressing environmental and societal issues To manage natural resources to benefit the nation To promote sustainable livelihoods To protect environmental quality (land, air and water) Land Use Change contributes to and is impacted by Climate Change

6 Example Land Use Questions How and where are Land Cover and Land Use Changing? What is driving Land Use Change? Salt Water Intrusion Economic Development Urban Growth Population growth and rural depopulation Land Tenure - who owns and who manages the land? Land speculation Land use policies Global Markets What are the impacts of Land Use Change Carbon cycle, water resources, livelihoods, biodiversity

7 Policy Relevant Land Use Questions Are current land use practices sustainable? Agriculture, Aquaculture Are biodiversity and habitats adequately protected? How are extreme climate events impacting Land Use Drought, Flooding Land Use Teleconnections and Transboundary issues Managing the Mekong Drainage Basin Land Productivity trends and potential Land use policies how to make them effective? How will land use change in the foreseeable future? What will the Land Use of the SARI region look like in 20 years given current trends?

8 The Other Global Change: Climate! Land Use as a means for Mitigation Emissions Inventory and GHG accounting Greenhouse Gas Reductions Post Paris Land Use Adaptation to Climate Change Extreme Weather Events (wet and dry) A Warming World Sea Level Rise Resilience of Land Use Systems to Climate Change Agricultural Systems Urban Systems

9 Some Earth Observation Questions Which satellite data are easily available for my study area? Which data are best for my application? How do I get hold of them - Data Access? How can I obtain microwave data as my study area is often cloudy How do I interpret the metadata? Are there best practices for processing, analysis, accuracy assessment, application? Are there consistent long-term satellite data records to monitor change? How do I use them to study land cover change?

11 Meeting Organized in Six Sessions Day-1-Monday (Oct-17) Session I. Regional and National Science Initiatives Session II. Agricultural Land Use and Emissions Day-2 (Oct-18) Session III. Inventories, monitoring and modeling of GHG s and air pollution Session IV. Vegetation Fires, Emissions and Aerosols emissions Day-3 (Oct-19) Session V. Forests and LCLUC Session VI. Urban LCLUC Session VII. Regional Discussion Session and Next Steps

12 Day-1-Monday (Oct-20) 3-Day Training Session I. Agriculture Emissions Session II. Land use/mapping/monitoring use high resolution data Day-2 (Oct-21) Session III. Agriculture Mapping and Monitoring using Optical and SAR data Day-3 (Oct-22) Session V. Atmospheric Transport Modeling Session VI. Python programming and applications Session VII. UAV for Land Use/Cover Mapping/Monitoring

13 Getting Familiar with Python

14 In Summary Meeting Objectives Review regional and national science initiatives relating to LCLUC activities. Review the causes and consequences of LCLUC (agriculture, forests, urban) in the Asian region; Review GHG and emission estimates and methodologies from different sources in the Asian region; Explore the potential of satellite remote sensing datasets for land remote sensing, emission inventories and air pollution mapping/monitoring. Strengthen the capacity building and training activities in the region

15 Proposed Meeting Outcomes Presentations will be posted on the SARI web site Summary Report (The Earth Observer) will be available on the SARI web site Journal Special Edition papers will be solicited emphasis on publications from and with regional scientists Hopefully Active bilateral collaborations within the region and globally Greater involvement of Vietnam in the South/Southeast Asia Regional Initiative on Land Cover and Land Use Change

16 ternational Workshop on LCLUC and Air Pollution in Asia Bog Indonesia 4-7 th August, 2015

17 These meetings provide a unique opportunity Please take advantage of them Introduce yourself to other attendees Ask questions of speakers Exchange ideas and information Share what you learn with your colleagues
