Climate change, population growth, unmet family planning needs, water scarcity, and changes in agricultural production are among the global challenges confronting governments and ordinary citizens in the 21st century. With the interactive feature “Mapping Population and Climate Change
” from Population Action International
, users can generate maps using a variety of variables to see how these challenges relate over time.
Users can choose between variables such as water scarcity or stress, temperature change, soil moisture, population, agriculture, need for family planning, and resilience. Global or regional views are available, as well as different data ranges: contemporary, short-term projections (to the year 2035), and long-term projections (2090).
In the example featured above, the variables of population change and agricultural production change were chosen for the time period 1990-2020. Unfortunately, no country-specific data is given, though descriptions in the side-bar offer some helpful explanations of the selected trends.
In addition, users can view three-dimensional maps of population growth in Africa and Asia for the years 1990, 2035, and 2090. These maps visually demonstrate the projected dramatic increases in population of these regions by the end of the century. According to the latest UN estimates, most of the world’s population growth will come from Africa and Asia due to persistently high fertility rates.
