Natural factors can cause changes to the quality of freshwater, and can also exacerbate the damage caused by human-made pollution. A wide range of human activities impact on freshwater bodies including: agriculture, forestry, horticulture, urban development, and mining.Abiotic factors include ambient temperature, amount of sunlight, and pH of the water soil in which an organism lives. Biotic factors would include the availability of food organisms and the presence of biological specificity, competitors, predators, and parasites.The determinants of health include:

Natural Factors:
Natural factors can cause changes to the quality of freshwater, and can also exacerbate the damage caused by human-made pollution. Algae grows best in a warm climate, so water bodies in warmer regions are more likely to experience algal blooms than those in colder parts of the country. The amount of rainfall that a water body receives controls the amount of water that flows in rivers and aquifers, and affects water quality by carrying pollutants from land to the water. At times of heavy rainfall, particularly after a dry period, much higher levels of pollutants may enter water bodies. The geology of the catchment will have an impact on the level of sediment carried by the water: mountainous regions where the catchments are steep-sided, or where the sediment is soft, are more likely to experience natural erosion causing rivers draining from these catchments to carry high levels of sediment.
Although these factors are important to consider when evaluating water quality, the main concern for managers of water resources are the impacts generated by New Zealand’s human population. A wide range of human activities impact on freshwater bodies including: agriculture, forestry, horticulture, urban development, and mining. Climate change is likely to place further pressure on lakes, rivers and streams.
Invasive fish and plant species are also of particular concern in freshwater ecosystems. Exotic species can displace native species upsetting the ecological balance.
