Geospatial Information Mdg’S And Malawi

  1. 1. Geospatial Information, MDG’s and Malawi
  2. 2. Overview <ul><li>What is Geospatial Information (GI)? </li></ul><ul><li>How can GI help meet the MDG’s? </li></ul><ul><li>GI in the UK and Malawi </li></ul><ul><li>Very High Resolution Satellite Imagery </li></ul><ul><li>Conclusions </li></ul>
  3. 3. What is Geospatial Information? <ul><li>Anything than can be linked by location </li></ul><ul><li>2 dimensional - map information – point, line, area </li></ul><ul><li>3 dimensional – topography, geology </li></ul><ul><li>4 dimensional – road/rail networks </li></ul><ul><li>Other GI - satellite imagery, diseases, climate, census </li></ul><ul><li>Metadata – eg water borehole </li></ul><ul><li>As much as 80% of information is spatially related. </li></ul>
  4. 4. What is Geospatial Information? <ul><li>A Geographic Information System (GIS) stores data digitally </li></ul><ul><li>Creates new information - explain events, predict outcomes, and plan strategies eg flood protection; crime prevention; climate modelling. </li></ul><ul><li>The major challenges we face in the world today - overpopulation, pollution, deforestation, natural disasters, climate change-have a critical geographic dimension . </li></ul>
  5. 5. How can GI help meet the MDG’s? <ul><li>MDG Africa Steering Group chaired by the UN Secretary General </li></ul><ul><li>“ Achieving the MDG’s…in Africa holds the promise of saving millions of lives..and ensuring that Africa’s children are empowered through education and good health to lead productive lives.” </li></ul><ul><li>At the halfway point only 3 African countries will achieve them by 2015 </li></ul><ul><li>“ Urgent action is needed to prevent hundreds of millions more people slipping into hunger – chronic hunger affects 1 in 6 people” OXFAM Jan 2009 </li></ul>
  6. 6. How can GI help meet the MDGs? <ul><li>Agricultural productivity </li></ul><ul><li>Nutrition and schools feeding programmes </li></ul><ul><li>Education </li></ul><ul><li>Health systems, child survival, maternal health </li></ul><ul><li>Family planning </li></ul><ul><li>Vertical disease control programmes </li></ul><ul><li>Infrastructure and trade facilitation </li></ul><ul><li>National statistical system </li></ul><ul><li>Comprehensive cross-sector public expenditure programmes against clear quantitative targets. </li></ul>
  7. 7. How can GI help meet the MDG’s? <ul><li>Agricultural Activity – doubling of food yields by 2012 </li></ul><ul><li>Crops – type, soils, gradients, climate, flooding, diseases, nutrition, pests, fertiliser…. </li></ul><ul><li>Water – rain-fed. wells, springs, taps, boreholes, rivers, streams, aquifers, irrigation systems, pollution, waterflow </li></ul><ul><li>Related information – pollution, boundaries, utilities, earthquakes, ownership, market demand+access+transport type, historical data, imagery, census, climate change scenarios </li></ul>
  8. 8. How can GI help meet the MDG’s? <ul><li>Will help answer questions like…….. </li></ul><ul><li>What sort of crops can I grow? </li></ul><ul><li>Is there repeat harvest potential? </li></ul><ul><li>Do I need fertilisers? </li></ul><ul><li>Do I need water? </li></ul><ul><li>What is the earnings potential? </li></ul>
  9. 9. GI in the UK and Malawi <ul><li>OS continually updates urban and rural township mapping </li></ul><ul><li>Large scale = lots of information </li></ul><ul><li>Maps converted into digital format </li></ul><ul><li>Correlated with GPS </li></ul><ul><li>Information is widely used by professionals for planning </li></ul><ul><li>£100 billion generated in the UK economy (4% GDP) through investment of £100 million </li></ul>
  10. 10. GI in the UK and Malawi <ul><li>Maps up to 45 years old; no update program though some data is digitised </li></ul><ul><li>Population has increased from 3 to 12 million > massive demographic changes </li></ul><ul><li>Mapping based on old projection > correlation with GPS collected points unreliable </li></ul><ul><li>MDG strategies affected at national and local level eg SWAP </li></ul>
  11. 11. GI in the UK and Malawi <ul><li>Initiatives like Africasoils; AfricaMap; WaterAid </li></ul><ul><li>Correlation of data an issue </li></ul><ul><li>No programmatic approach to collection and maintenance of national datasets. </li></ul><ul><li>Commercial enterprises collect datasets for a specific project. Data not shared. </li></ul><ul><li>Many African NMOs are poorly resourced </li></ul>
  12. 12. Very High Resolution Satellite Imagery <ul><li>No restrictions </li></ul><ul><li>Low cost - $10 archive to $40 stereo/sq km – Blantyre £5000 </li></ul><ul><li>0.4m pixel resolution </li></ul><ul><li>8 band multi-spectral capability </li></ul><ul><li>Stereo - Geology, hydrology, topography </li></ul><ul><li>Almost daily revisit </li></ul><ul><li>3d visualisation for environmental impact </li></ul>
  13. 15. Conclusions <ul><li>GI and achievment of MDG’s are interlinked </li></ul><ul><li>Reliable and contemporary GI is crucial to development </li></ul><ul><li>Dated and limited GI in Malawi severly restricts planning </li></ul><ul><li>Modern cost effective GI Technologies can satisfy many of the requirements for base mapping </li></ul><ul><li>GIS facilitates knowledge sharing </li></ul>
  14. 16. Conclusions <ul><li>Invest in Malawi National Mapping Agency – hardware, software, training - each £1 invested in mapping could generate £1000 to the economy </li></ul><ul><li>Need to establish a national GPS control network and height model </li></ul><ul><li>Developing GIS skill base will encourage outsourcing from the West </li></ul><ul><li>Further research required in VHRSI accuracy, processing and image recognition </li></ul><ul><li>Set up national system of geospatial data collection and management </li></ul>
