Over the 5,000 years since pastoralism emerged as a land use system in sub-Saharan Africa, pastoral natural resource management and herding strategies have modified ecosystems to such an extent that removal of pastoralism can be detrimental to grazing ungulates and rangeland diversity (Lamprey and Waller 1990).
Hence, reduction in level of NO−3 in water bodies and ground water is a prerequisite that can be met through sustainable management of natural and modified ecosystems.
Humans have substantially influenced and modified ecosystems in the past by introducing anthropogenic pollutants and waste into these systems.
Our approach could be broadly applied to the assessment and management of modified ecosystems, especially where historical data are available to calculate measures of biotic novelty.
Some irreversible, negative effects of soil sealing are impermeable ground and modified ecosystems (bio-geochemical cycle, water cycles, loss of biodiversity, etc)., which alter matter and energy flows and the ecological functions of the soil.
In a continental context, the evidence from these studies are consistent with the idea that in South America, early settlers modified ecosystems through the selection and exploitation of useful species, thus generating anthropogenic landscapes beginning as early as the Pleistocene Holocene transition.
Within the continuum of natural-to-novel ecosystems − i.e., from the 'pristine' to the greatly intervened − this paper emphasizes the role of design within highly modified ecosystems in areas of urbanization.
Agricultural land management modifies ecosystem structure and functioning in natural landscapes.
Fire disturbance severely modifies ecosystem structure and functioning, and therefore predicting post-fire responses is pivotal to improve land management.
In addition, the rate at which temperature modifies ecosystem respiration (parameter B) increases as SWC increases, this effect is particularly evident when changing from low to medium relative soil water content (RWC, equation 2) values.
