ESS (IBDP) 8.1 human systems and resource use: unit of work

Entire planned unit of work for Environmental systems and societies, ready to pick up and teach - no extra planning needed.

Covers:
Demographic tools for quantifying human population include crude birth
rate (CBR), crude death rate (CDR), total fertility rate (TFR), doubling time (DT)
and natural increase rate (NIR).
• Global human population has followed a rapid growth curve, but there is
uncertainty as to how this may be changing.
• As the human population grows, increased stress is placed on all of the
Earth’s systems.
• Age–gender pyramids and demographic transition models (DTM) can be
useful in the prediction of human population growth. The DTM is a model
that shows how a population transitions from a pre-industrial stage with high
CBRs and CDRs to an economically advanced stage with low or declining CBRs
and low CDRs.
• Infuences on human population dynamics include cultural, historical,
religious, social, political and economic factors.
• National and international develo
