2.1 Descrição curta da tecnologia

Definição da tecnologia:

Construction of indigenous water pond and a livestock watering trough along an underground water source.

2.2 Descrição detalhada da tecnologia

Descrição:

This technology is used during the dry seasons and where ground water level is high and there is natural water stream flowing from underground water source. Water pond is excavated along the naturally flowing water stream and is recharged by natural ground water. The size of the pond will vary depending on the area available, groundwater table, slope and soil characteristic. Groundwater collection ponds described in this technology on average are 4m long, 3m wide and 1m deep of 12m3 (12 000 liter) capacity and the slope is moderate 5% to 8% and soil characteristics is clay loam with deep soil. Water troughs (Elyato by local name) are constructed adjacent to the water pond to allow livestock to access clean drinking water. The number of troughs per pond is usually 1 to 2. Materials used in construction of water trough include clay, red termite mound soil, grass and wooden poles. The number of ponds needed usually depends on the expected number of animals and are arranged at irregular intervals ranging from 10 to 20 meters apart. The average size of a water trough is 0.14 m3 and can cater for 5 cattle at a time. The Pond is stabilized by naturally growing grass on its banks. Common pond stabilizer species are Leodicatiar digitalia and Hyperrhenia rufa. Management of the natural water source is through preventive village/customary by-laws which prohibit tree and grass cutting around the water source. The dominant indicator tree species normally found are Erythrina abysinica, Ficus thorgii and Phoenix recrinata. The animal watering troughs are usually used in the dry period. Before watering the troughs are coated (smeared) with red termite mound soil (normally hand carried by herders) to provide a good taste which is attractive to animals. Water is transferred from the pond to the water trough manually using cans or buckets. Animals drink directly from the troughs. This water from the trough is rich in iron (Fe) from red termite mound soil. The troughs are constructed with outlets used to spill out water immediately after drinking in order to prevent their damage through excessive water saturation.

Purpose of the Technology: This technology is preferred by livestock keepers as it provides for animals to drink clean and mineralized water and for health improvement. User fee payed to land owners also enable them to expand and diversify there income sources.

Establishment / maintenance activities and inputs: Establishment: Land clearing, excavation and shaping of water pond and construction of animal watering trough.
Maintenance: repair of water pond and water trough (de-siltation, grass slashing and gap refilling).
Inputs: labour, implements (machete, spade, hand hoe, sickle), clay, red termite mound soil, wooden poles, buckets, grass and tying rope. Average establishment cost for one pond and its water trough is 41.27 American dollars. Average annual maintenance and recurrent costs (filling and emptying of water trough) for one pond and its water trough stands at 458.76 dollars and labour is a core cost determinant factor.

Natural / human environment: Natural environment: Extensive grazing land. The technology is largely structural (excavation and shaping of water ponds and construction of water troughs) supported by the use of by-laws which prohibit destruction of the protective natural and indicative trees and grasses around. The technology is common in sub-humid climatic zone.
Social economic environment: Level of mechanization is handy tools with subsistence production systems on individual fields.

3.7 Principais tipos de degradação da terra abordados pela tecnologia

Comentários:

Main causes of degradation: deforestation / removal of natural vegetation (incl. forest fires) (cutting of natural tree and removal of grass along the natural water flow way), overgrazing (Compaction by trampling animals, rainfall runoff, siltation of water collection point and disapearence of vegatative cover.), discharges (point contamination of water) (spoilage and contamination of surface water by human and livestock feaces.), population pressure (Overstocking due to increase in the number of livestock), poverty / wealth (low capacity to invest in enviromental friendly energy sources), inputs and infrastructure: (roads, markets, distribution of water points, other, …) (Unavailable improved and reliable water ponds and animal watering troughs), education, access to knowledge and support services (limited knowledge on sustainable use of natural water sources), governance / institutional (limited enforcement of existing environmental regulatory systems.)

Secondary causes of degradation: soil management (excavation and layout that contradict the natural environment), crop management (annual, perennial, tree/shrub), over-exploitation of vegetation for domestic use (fire wood collection from the natural water source), industrial activities and mining, urbanisation and infrastructure development, release of airborne pollutants (urban/industry…), disturbance of water cycle (infiltration / runoff), over abstraction / excessive withdrawal of water (for irrigation, industry, etc.), other human induced causes (specify), change in temperature, change of seasonal rainfall, Heavy / extreme rainfall (intensity/amounts), wind storms / dust storms, floods, droughts, other natural causes (avalanches, volcanic eruptions, mud flows, highly susceptible natural resources, extreme topography, etc.) specify, land tenure, labour availability, war and conflicts
