Technology of remote sensing and ground monitoring of ecological and ameliorative conditions of pastures

Author: Knowledge Management in CACILM Phase II, ICARDA.

Definition of technology:

Use of aerospace images and ground monitoring for assessment of ecological and reclamation conditions of pasture areas and operative decision-making.

Brief summary of technology:

Insufficient sustainability of desert forage complexes, especially under the influence of anthropogenic factors, necessitates a systematic or periodic monitoring of desert rangelands, receiving operative information about the direction and scale of changes.

Application of remote sensing methods for monitoring of vegetation of desert areas is mostly related to the inaccessibility of these areas. Aerospace pictures are informative and have a considerable visibility, therefore allow assessing the situation objectively and taking effective measures to conserve natural forage pastures and use them rationally.

Location: Moyunkum district, Zhambyl province.

Area of technology application: 14700 ha.

Stage of intervention: prevention of land degradation.

Main land use issues and the main causes of land degradation:

Low productivity of the pastures due to inefficient use of fodder resources; pasture degradation due to water deficits and overgrazing near existing wells and settlements.

Difficulty of ground inspection of condition and assessment of fodder capacity of pastures complicates operative decision-making.

Main technical features of technology:

Spatial regulation of the usage of fodder resources and ability to manage productivity of pastures.

Type of land use Conservation measures

Pasture land.

Extensive Pasture land - Пэ(Ge).

Management measures:

У1: changing the type of pasture use - open pastures, cultivated pastures, including enclosures;

У3: planning according to natural and human needs;

У5: change in rotational sequence, control and diversification of species composition.

Environment

Habitat 

Average annual rainfall: 250-500 mm.

Altitude (meter above sea level): 100-500 m.

Landscape: plains.

Slope (%): 0-2% (flat, smooth).

Soil fertility: low.

Humus content in arable horizon: not more than 1%.

Natural soil drainage/infiltration: moderate, less than moderate.

Anthropogenic environment

Size of land area (ha): 1 000-10 000 ha.

Landholder: small holders.

Land ownership: state; long term lease.

Water use rights: rental agreements for water use.

Market orientation: Mixed farming (subsistence and commercial).

Assessment

Impact of technology

Main advantages:

- increasing operative decision making on improving conditions of pastures;

- reducing production costs;

- increasing plant diversity, livestock production and farm income.

Main disadvantages:

- complexity of mapping of pasture land in the initial phase.

Acceptance/adoption of technology: The technology has been tested and recommended for use
