The Natural Step
Four basic rules, or sustainability principles, which can be contextualised to turf management:
• Reduce the use of artificial materials and do not pollute the environment;
• Reduce natural resource consumption and use, including CO2 emissions, and increase the use of renewables;
• Do not degrade nature by physical means, including reducing erosion and water consumption;
• Encourage the health, well-being and development of self and others.
