  1. Gridded-Pop WorkshopMay 2-3, 2000 Human Population and the Biodiversity Hotspots Richard Cincotta, Robert Engelman and Jennifer Wisnewski

  2. A Case for Considering the Low-end User of Gridded Pop Data

  3. Who are low-end users? • NGOs and other researchers using ArcView or other GIS viewing applications • with or without spatial analysis programs.

  4. What will they do with GPW? • Population density can be associated with risk to various resources, infrastructure and capital. • Population density can be associated with exposure to risks from hazards.

  5. What do low-end users need? • Standardization of data and procedures (comparable to UN Population Division procedures). • Some hints/guidelines for use and display.

  6. The Biodiversity Hotspots (25) and Major Tropical Wilderness Areas (3) Conservation International

  7. Displaying GPW for Biodiversity Audience Most Dense: >300 people km-2 150 - 300 50 - 150 15 - 50 5 - 15 1 - 5 Least Dense: 0 - 1

  8. Population in the Global Biodiversity Hotspots 1995

  9. Findings: Biodiversity Hotspots • As of 1995, more than 1.1 billion people were living within the 25 biodiversity hotspots. • The original extent of the hotspots cover just 12 percent of the planet’s land area but are home to about 20 percent of the world’s population.

  10. Findings: Biodiversity Hotspots • Aggregate population growth (1995-2000) in the 25 hotspots (1.8%/yr) is more rapid than the world as a whole (1.3%/yr). • In 1995, aggregate population density in the hotspots (72 people/km2) was greater than that of the world as a whole (42 people/km2).

  11. Population in the Global Biodiversity Hotspots 1995

  12. Major Tropical Wilderness Areas • Population is growing at a rate of 3.1 percent annually – about 2.5 times the world’s average population growth rate.

  13. Science & Technology • Short article in Nature(27 April 2000 issue, pp. 990-992) • Forthcoming article for GIS-users in ArcNews

  14. Policymakers • Forthcoming article for policymakers: Issues in Science & Technology • UNDP/GEF sponsored priority-setting workshop for the West African Hotspot (Dec. 1999). • Centerpiece for report: Nature’s Place

  15. Public Audiences • Population section on Conservation International wall map. • Analysis recommended for Pennsylvania state high school environmental science curriculum. • Press & Popularization

  16. Recommendations • A Standard Time Series (e.g., 1995, 2000, 2005, … ) -- with procedures for updating those intervals based on new estimates. • Historic estimates: (e.g., 1975 or 1950). • Discussions of Projection Methods.
