    Assessing rural resources and livelihood development strategies combining socioeconomic and spatial methodologies. Krishna Bahadur Assessing rural resources and livelihood development strategies combining socioeconomic and spatial methodologies. Krishna Bahadur Presentation Transcript

    • Assessing rural resources and livelihood development strategies combining socioeconomic and spatial methodologies Krishna Bahadur KC Center for Southeast Asia Studies Kyoto University Friday, October 28, 2011
    • Structure of the presentation
      • A view of the rural regional system in mountains of South and Southeast Asia
      • The need for integration of socioeconomic and spatial concepts and methodologies
      • The methodological discussion: concepts of integration
      • Potentials and limitations in applying the integrated concept with empirical examples
      Friday, October 28, 2011
    • Spatial gradients of the rural region
      • Natural resource distribution and changing land use in the area
      • spatial distribution of ethnic groups or farming families
      • Associated man-made problems alongside the spatial gradients
      • Changing infrastructure with increasing distance from urban centers to remote areas
      Friday, October 28, 2011 Decreasing: income food security health care education Ownership right environment problems resource conservation Change of structures in production and marketing tradition and culture family ties Increasing: city villages bush forest migration increasing market distance decreasing population density
    • The need for integration of socioeconomic and spatial concepts and methodologies
      • The need for integration is manifold, but the following can be considered as the main reasons:
      • Remote sensing and GIS provide tools and are applied in the frame of concepts which improve data bases in natural sciences for rural development (traditionally not covered by socioeconomic concepts)
      • Socioeconomic (economics/agricultural economics) provide concepts strongly based on people’s views and cover a large area of behavioral and decision-making processes at family and regional levels (traditionally not covered by GIS concepts)
      • Combining both concepts would allow to improve not only the knowledge systems but also the analyses of past development and provide ample scope for improving future strategy testing with family and regional simulation models

    • The methodological discussion Concepts of integration Friday, October 28, 2011
    • Methodological approach Spatial level Family level Satellite Analogue physical Soil Farming system survey images maps data data Socioeconomic data GPS position Land use/change Soil loss Spatial Cost distance farm/family income Land quality indexes water availability food production Linking, integrating and analysis Image analysis Interpolation Modeling the current situation and measuring the impact of future strategies Digitization, surfacing, lab test (Spatial analysis & modeling) Thematic layers Friday, October 28, 2011
    • Some reflection from biophysical/spatial analysis Friday, October 28, 2011
    • Examples of land and water resources development Change of land and water resources Ing Watershed Thailand Land use change in Galaudu Watershed Nepal Friday, October 28, 2011

    • Mountain landscape and land degradation Wire Mesh Representation Upper Nam Wa Watershed Thailand Data Source : Digital Elevation Model Friday, October 28, 2011
    • Assessing the impact of land use changes on land degradation, Galaudu Nepal (2000) Friday, October 28, 2011
    • Friday, October 28, 2011
    • Assessing the strategic spatial water availabilities and their impact to local economy Friday, October 28, 2011
    • Simulated flow in the Upper Ing Watershed, Thailand at the watershed outlet, with actual precipitation and land use data 20/09/11 0 10000 20000 30000 40000 50000 60000 Sep 98 Mar 99 Base Flow River Flow Sep 99 Mar 00 Sep 00 Mar 01 Sep 01 Mar 02 Sep 02 Mar 03 Sep 03 Mar 04 Sep 06 Sep 04 Mar 05 Sep 05 Mar 06 Sep 07 Mar 07 Flow rate (L/Sec) Friday, October 28, 2011
      • Optimising the location of new reservoir and cropping system
      • Measuring the impact of “land use change on spatial water availability and water system“
      • Measuring the impact of ‚climate change such as “more rain fall scenario“ on spatial water availabilities and water system
      Application of spatial simulation models Spatial water budget model developed for Upper Ing Watershed was used to simulate future development and measure the impact of future strategies such as: Friday, October 28, 2011
    • Location of proposed dams at the simulated river network with land use 2005 Irrigated area Zone 7 Zone 6 Zone 5 Zone 3 Zone 4 Zone 2 Zone1 Zone 8 Friday, October 28, 2011

    • Some reflection from socioeconomic analysis Friday, October 28, 2011
    • Distribution and variation of family income in the Upper Ing Watershed Thailand Friday, October 28, 2011
    • Farm income and irrigated land relations in the Upper Ing Watershed, Thailand Farm income (Baht/household) Irrigated area (Rai) Household classification based on socioeconomic and spatial characteristics Friday, October 28, 2011
    • Potentials and limitations in applying the integrated concept under practical conditions Cases from mountains of South and Southeast Asia Friday, October 28, 2011
    • The relation between land use change and factors of regional development Results of GIS analysis: land use change from 1990 to 2000 Integration of results of micro level family income analysis altitudinal gradients road distance Distance to markets Friday, October 28, 2011
    • Assessment of land management on farm income, Galaudu Watershed, Nepal Friday, October 28, 2011
    • Assessment of road improvement on farm income, Galaudu watershed, Nepal Friday, October 28, 2011
    • Impact of irrigation improvement on incomes, Ing watershed Thailand Friday, October 28, 2011
    • Friday, October 28, 2011
    • Conclusions It has been proven that the integration of family survey information and data from remote sensing & GIS can be used in a combined analysis and future impact assessment, to find out appropriate development strategies. Empirical results demonstrate: Future problem solving strategies such as: development and improvement of road network, development and improvements of irrigation water and land and soil conservation strategies such as building terraces demonstrated the possibility of improving living standard and sustainable management of natural resources in the mounts of south and south east Asia. Further research is needed to explore the full potentially of integrated spatial approach not only land and water resources but also on other resources of farming and rural regional setups.
