Water cycle: water is the key source for life because all organisms and communities need it.
Nutrient cycle: all living organisms needs nutrients (i.e. food) to live, grow and reproduce.
Energy cycle: energy is key in all what we do, it is driving motor.
The processes for correcting biotic factors, which emerge from the system itself, keep the system in balance are numerous. There are many feedback mechanisms.
In case of getting out completely out of balance there is in nature which is about succession, regulating high dynamics (new emerging and recovery processes). Compared to society we can speak of rebuilding and recovering from crises and disasters.
If we strive for an equilibrium in our public ecosystem then we will have to respect and embed the main cycli of water, nutrients and energy in the first place and know how to manage the biotic balance and recovery in the second place.
From ecology perspective these as core constraints for all the balance act of public value management in city, regions and countries. They are starting points for public governance and for key processes of developing and managing the society.
Multi-level governance: the process of connecting with higher and lower levels of society (from Europe to the street). It is a key process to travel across the borders of the different levels of the ecosystem.
Creation: the process of from sensing of trends, developing strategy and policy plan and implement and monitor them related to desired public value.
Delivery: the process of communicating with stakeholders and the acutal delivery of products and services.
Financial Engineering: the process of collecting and budgetting financial sources to make things possible.
Compliancy: the process of acting and working according the legislation and rules by checking, verifying, auditing, supervising, examining and measuring correctness.
System correction: the process of prompt, immediate and accurate management of crises and disasters to bring society back into balance, i.e. recovery process. These can be related to biotic factors as diseases or abiotic factors as flooding.
