Land management

From Wikipedia, the free encyclopedia

Land management is the process of managing the use and development of land resources. One aim of sustainable land management is to prevent or reverse land degradation. Another aim is to ensure water security by increasing soil moisture availability, decreasing surface runoff, and decreasing soil erosion.[1] Land resources are used for a variety of purposes which may include for example agriculture, forestry, water resource management, human settlements and tourism. Unsustainable land managements leads to land being over- or misused which in turn degrades the land, reduces productivity and disrupts natural equilibriums.[2]

Sustainable land management (SLM) refers to practices and technologies that aim to integrate the management of land, water, and other environmental resources to meet human needs while ensuring long-term sustainability, ecosystem services, biodiversity, and livelihoods.[3]: 2924 

Definition

[edit]

The IPCC Sixth Assessment Report describes land management as "The sum of land-use practices (e.g., sowing, fertilising, weeding, harvesting, thinning and clear-cutting) that take place within broader land-use categories."[3]: 2914  Land use itself is "The total of arrangements, activities and inputs applied to a parcel of land." Land use categories include: forest land, cropland (agricultural land), grassland, wetlands, settlements and other lands.[4]: 2914 

The United Nations Economic Commission for Europe (UNECE) applies the term land management in a wide context. Besides agriculture and forestry, they include the mineral extraction sector, property and estate management: "Land management is the process by which the resources of land are put to good effect. It covers all activities concerned with the management of land as a resource both from an environmental and from an economic perspective. It can include farming, mineral extraction, property and estate management, and the physical planning of towns and the countryside.[5]: 13 

Sustainable land management (SLM)

[edit]

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.

SLM has been defined in various reports as follows:

  • By IPCC in 2022: "The stewardship and use of land resources, including soils, water, animals and plants, to meet changing human needs, while simultaneously ensuring the long-term productive potential of these resources and the maintenance of their environmental functions".[3]: 2924  This wording is very similar to the longer wording used by the United Nations (UN) 1992 Rio Earth Summit in 1992: “The use of land resources, including soils, water, animals and plants, for the production of goods to meet changing human needs, while simultaneously ensuring the long-term productive potential of these resources and the maintenance of their environmental functions.”[6]
  • By World Bank in 2006: "SLM is defined as a knowledge-based procedure that helps integrate land, water, biodiversity, and environmental management (including input and output externalities) to meet rising food and fiber demands while sustaining ecosystem services and livelihoods.[7]: xiv 

Purposes

[edit]

One aim of sustainable land management is to prevent or reverse land degradation. Another aim is to ensure water security by increasing soil moisture availability, decreasing surface runoff, and decreasing soil erosion.[1]

A World Bank report in 2006 explained: "SLM is necessary to meet the requirements of a growing population. Improper land management can lead to land degradation and a significant reduction in the productive and service (biodiversity niches, hydrology, carbon sequestration) functions of watersheds and landscapes."[7]: xiv 

Methods

[edit]

The current practices of sustainable land management (SLM) for example in Ethiopia involve a variety of structural and nonstructural elements integrated at the catchment scale, providing different roles in managing water resources. For instance, the structural measures (soil bunds, contour trenches, etc.) significantly improve infiltration and water storage potential of the agricultural landscapes. On the other hand, the nonstructural measures, such as the elimination of open grazing on communal grazing land and the abandonment of postharvest grazing on cultivated land, help improve the water retention capacity of the soils and reduce nonproductive evaporative water losses.[6]

In addition, the current practices of SLM attempts to sustain diverse land use mosaics at the catchment scale, including protected areas (gullied lands and communal grazing lands), cultivated land and home gardens, with the aim of harnessing potential uses, services, and values from a catchment.[6]
