Clone of 2014 Weather & Climate Extreme Loss of Arable Land and Ocean Fertility - The World3+ Model: Forecaster

Christopher Bystroff

The World3 model is a detailed simulation of human population growth from 1900 into the future. It includes many environmental and demographic factors.

Predators keep the balance

Christopher Bystroff
Humans were once the prey of many predators. In this insight, the human death rate is exclusively due to predators and proportional thereto. Predators death rate is exclusively due to famine and humans are their only food. The results is a robust population balance.

Food-limited human growth

UN model

Demographic transition model.
As technology increases linearly, the death rate drops first, then the birth rate. Population equilibrates at a higher level. 
This is a demonstration of the Storytelling and Publishing capabilities of InsightMaker.

Nature and People, together

Christopher Bystroff
This is part 3 of the Feb 10-17 exercise for Human Population. The Nature model (ecological footprint versus biocapacity) plus the People model (exponential growth with affluence dependent birth and death rates) are connected using the I=PAT model (impact on Nature depends on affluence).

IPAT v.1.0

Christopher Bystroff
This is a first attempt to model I=PAT population growth. Impact on the renewables is equal to P*A*T. Footprint is limited by the amount of renewables left divided by the population. Death rate goes up if the Footprint goes down too far.
