To keep control on wildlife deer populations two means are available; killing by hunters or sterilization and castration. This model allows investigating the best possible method and …  actual risk on extinction caused by proposed solutions!

Note 1) Data used in this model are fictitious.

Note 2) Govenrments preferred solution are hunters because this will generate income from licences, sterilization and castration only will generate costs; forester, transport, vet, medical. govenrments should make a stand up for the animals.

Note 3) Other solutions do exist and detail could be added to this analysis model that could result in even better solutions.

This is a basic BIDE (birth, immigration, death, emigration) model.  Not all parts are implemented, however Birth and Death are.

This simulation examines carrying capacity of rural and urban populations

This is a basic BIDE (birth, immigration, death, emigration) model.  Not all parts are implemented, however Birth and Death are.

Assessment 4.

This model highlights the interdependent relationship between:

Show relation of birth and death rate over time, creating the elements of the demographic transition. This one is for Indonesia. You can clone this insight for other nations, just plug in the new crude birth and death rates and find the starting population in 1960.

OVERSHOOT GROWTH GOES INTO TURBULENT CHAOTIC DESTRUCTION

The existing global capitalistic growth paradigm is totally flawed

The chaotic turbulence is the result of the concept of infinite bigness this has been the destructive influence on all empires and now shown up by Feigenbaum numbers and Dunbar numbers for neural netwoirks

See Guy Lakeman Bubble Theory for more details on keeping systems within finite limited size working capacity containers (villages communities)

Simulation of Population

Modelagem do estado psicológico de uma população. Inicialmente, todos os indivíduos estão no estado "Calmo". Com o passar do tempo e com as interações mútuas, há o surgimento e progressivo aumento do total de indivíduos com raiva (estado "Raivoso"). Deste estado e, com o passar do tempo, os indivíduos podem evoluir mentalmente e atingirem o estado "Indiferente", nos quais eles se tornam indiferentes à qualquer interação. Outra possibilidade é o indivíduo se enriquecer e, assim, atingir a felicidade (estado "Feliz").

​Population model where the population is summarized in four age groups (children, parents, older people, old people). Used as a base population model for dealing with issues such as employment, care for the elderly, pensions dynamics, etc.

Shows the ecological impact of population.

Influence of migration on the number of working-age population.

This model is under construction, not at all ready, don't use it for any purposes (my suggestion ☺) yet.

This in-depth concept map portrays the factors influencing koala births and deaths in SEQ. It also shows that the eucalyptus tree population in SEQ is vital for the survival of the koala.

Show relation of birth and death rate over time, creating the elements of the demographic transition. This one is for Australia. You can clone this insight for other nations, just plug in the new crude birth and death rates and find the starting population in 1960.
