The aggregate impact of many local land system changes has far reaching consequences for the Earth System, that feedback on ecosystem services, human well-being and decision making. [2] As a consequence, land system change is both a cause and consequence of socio-ecological processes. The Global Land Programme (GLP) of Future Earth is an ...
Ecosystem services are the various benefits that humans derive from healthy ecosystems. These ecosystems, when functioning well, offer such things as provision of food, natural pollination of crops, clean air and water, decomposition of wastes, or flood control. Ecosystem services are grouped into four broad categories of services.
Terrestrial ecosystems occupy 55,660,000 mi 2 (144,150,000 km 2), or 28.26% of Earth's surface. [5] Major plant taxa in terrestrial ecosystems are members of the division Magnoliophyta (flowering plants), of which there are about 275,000 species, and the division Pinophyta (conifers), of which there are about 500 species.
Although definitions of ecosystem management abound, there is a common set of principles which underlie these definitions: A fundamental principle is the long-term sustainability of the production of goods and services by the ecosystem; [52] "intergenerational sustainability [is] a precondition for management, not an afterthought". [43]
Sustainable land management (SLM) is a process in a charged environment between environmental protection and the guarantee claim of ecosystem services on the one hand. On the other hand, it is about productivity of agriculture and forestry with respect to demographic growth and increasing pressure in land use.
According to Richard Forman and Michel Godron, [22] a landscape is a heterogeneous land area composed of a cluster of interacting ecosystems that is repeated in similar form throughout, whereby they list woods, meadows, marshes and villages as examples of a landscape's ecosystems, and state that a landscape is an area at least a few kilometres ...
Some ecosystem services include those that provide and regulate resources, support natural processes, or represent culture. [25] Provisioning services provide resources to humanity, such as fuel and water, while regulating services include carbon sequestration , climate regulation, and protection against disease. [ 26 ]
For example, ecosystems do not serve as singular resources but rather are function-dependent in providing an array of ecosystem services. Additionally, this type of stewardship recognizes resource managers and management systems as influential and informed participants in the natural systems that are serviced by humans.
