Human Population and the Biodiversity Hotspots

A Case for Considering

the Low-end User of

Gridded Pop Data


Who are low-end users?

  • NGOs and other researchers using ArcView or other GIS viewing applications

  • with or without spatial analysis programs.


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.


What do low-end users need?

  • Standardization of data and procedures (comparable to UN Population Division procedures).

  • Some hints/guidelines for use and display.

Population in the Global Biodiversity Hotspots

1995


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.


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).

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.


Science & Technology

  • Short article in Nature(27 April 2000 issue, pp. 990-992)

  • Forthcoming article for GIS-users in ArcNews


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


Public Audiences

  • Population section on Conservation International wall map.

  • Analysis recommended for Pennsylvania state high school environmental science curriculum.

  • Press & Popularization


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.
