ການກຳໜົດຄວາມໝາຍ ຂອງເຕັກໂນໂລຢີ:

Water Spreading (or Spate Irrigation system) conducted through the construction of earth dam structures at the khor cross section.

2.2 ການອະທິບາຍ ລາຍລະອຽດ ຂອງເຕັກໂນໂລຢີ

ການພັນລະນາ:

Water Spreading (or Spate Irrigation) can be done through the construction of an angled bank or weir – with a spillway in case of excess flow – to divert a “khor” (ephemeral stream) and spread it (using spaced contour bunds) for crop production.

Water Spreading from khors or wadis where channelized runoff/ floodwater is diverted onto plains which are then cultivated on residual moisture. An example of a scheme which was constructed in 1999 is located at Hashitribab, some 7 km from Sinkat on the road towards Kassala. This scheme, comprising a stone-pitched earth diversion barrier across a khor (an ephemeral water course), is documented by using among others the WOCAT Questionnaire and WOCAT’s QA. While the diversion is still intact and provides water to the fields about one kilometre downstream (there were young sorghum plants growing at the time of the visit in November 2011) maintenance will be needed.
There was only a very small input of voluntary labour in its original construction (comprising a contribution in terms of stone pitching).

Construction by the Government, using machinery, with little local contribution might explain why voluntary maintenance of the structures has been negligible. Water spreading schemes have gradually expanded in number over the last 20 years in Red Sea State (according to Sayed Dabloub’s personal comment). Currently it was confirmed that there are new sites under planning and construction.

The purposes of diversion dam construction was to divert the main water course to take its way in the crop growing area replacing the old one and being controlled by small diversion dams (terraces to spread water for even water distribution through the original land. These terraces remarkably reduce gully formation.
Most important purpose is to provide water to growing crops in an area which is too dry for rain fed production and where no source for irrigation is available. It secures moisture during the growing season, by allowing more water to penetrate soil and to preserve moisture for a longer period at plant root zone.
The decrease of flood water velocity leads to silt accumulation and other debris materials which increase soil capability in providing moisture, nutrients and maintain soil structure and conservation.

For the earthen/stone-pitched diversion structure with spillway and small haffir alongside machines have been used (mainly loaders provided by the government) which excavated and built the bund. In addition local communities were involved in some aspects of the establishment (mainly stone pitching) supported/subsidized with incentives. The structure/scheme at Hashitribab (close to Sinkat) was built in 1999 (and no maintenance has been done since that time). It helps in watering about 500 feddan (c. 200 hectares) of agricultural area where water is spread by the use of small contour bunds: these were also constructed using subsidies and machines.
Terraces are usually used to control water spreading along the cropped area. Those terraces usually receive the water at low speed velocity. For that reason they are very small in size and volume. Usually they are located in very gentle and uniformed areas. The terraces can be constructed by simple hand tool and tractors accessories. But the prolonged drought makes the maintenance difficult as the dry soil is more susceptible to wind erosion and sand accumulation on both sides of the dam and the bottom of the bund is one of several desertification phenomenon in the region. But the wind-blown sand is one of the most serious one especially in the dry lands of the Red Sea State. Contour survey for land leveling slope identification and location is an important step before implementation.

The study site is located in the arid region of Red Sea State where steep hills from north-south inland mountains are interrupted by arid plains. The population density is low and the population depends on both cropping and livestock with high incidence of poverty. For this reason there should be a clear plan for construction and community extension approach to care about the maintenance of the technology. About 120 families live in Hashitribab area. All the year round they secure their provision by storing food crops in particular sorghum.

ຄວາມຄິດເຫັນ:

Major land use problems (compiler’s opinion): Soil vulnerability to erosion due to rainfall irregularity and characterized by drought cycles; in some years rainfall recorded complete absence. Bare and and dried soils are easily affected by erosion agents (wind and water erosion) as these soils are weakly tolerant. Soils in plains are very poor, not renewable and are affected more than soils in seasonable rivers which are renewable with high soil water moisture.
Major land use problems (land users’ perception): Rain fed soils are weak in moisture holding capacity contrast to soils in flush irrigation soils and preferably used for seasonal cultivation by users and producing stable food crops with good productivity besides all underground water for human consumption and livestock through wells at reasonable depths are to be found.
Future (final) land use (after implementation of SLM Technology): Cropland: Ca: Annual cropping

Main causes of degradation: crop management (annual, perennial, tree/shrub) (Clearance of land from resdues to mitigate erosion), overgrazing (Stocking at trees and shrubs continue during the flowering stage preventing seeds production.), industrial activities and mining (To manage mining activities.), change in temperature (Reduced rainfall rate and more affection by wind erosion.), change of seasonal rainfall (More unpredictable and uncertain), Heavy / extreme rainfall (intensity/amounts) (affect in water erosin), droughts (affect passively on the vegetation cover and disintegration of rural families.), poverty / wealth (Not able to conserve resources)
Secondary causes of degradation: soil management (Breaking and blanking soil clods, and leveling and furrowing to increase soil roughness specially at wet seasons to reduce water erodability.), deforestation / removal of natural vegetation (incl. forest fires) (excessive use of tree products), over-exploitation of vegetation for domestic use (Rising population and thus more resource requirements. This is typically is round growing population at urban at centres unlike to people in rural areas except at rainy season where they are gathered), urbanisation and infrastructure development (Sequence to absence of infrastructures and related problems of drought increased rural migration to urban areas.), wind storms / dust storms (Erosion of top soil by wind blown.), floods (unless controlled), inputs and infrastructure: (roads, markets, distribution of water points, other, …) (Blocking water flow in some areas), education, access to knowledge and support services (Low environmental awareness and preparedness.)
