Update, Conclusions, and Recommendations …
297
of agricultural soil nearby from deterioration due to the processes of salinity
increasing of soil and water.
26. Assessment of the hydrological and hydrologeological conditions of the groundwater aquifer (number of wells—discharges—groundwater level—productivity—groundwater chemistry—etc.) is required to further understand the
problem of environmental protection in Dakhla Oasis.
27. Conducting a topographic survey is necessary to determine the areas of natural
depressions that can be used for drainage ponds to be at a level lower than that
of agricultural lands and drains.
28. Geological, hydrogeological and geophysical investigations are required to
select the most appropriate locations to recharge the groundwater aquifer with
the excess water and to compensate the groundwater reservoir in the areas of
wells that are mechanically discharged.
29. A study of irrigation systems in Dakhla Oasis is necessary to change the irrigation systems from irrigation by flooding to sprinkling or drip irrigation, and to
reduce water losses and reduce the amount of wastewater received in the drains.
30. The increase of wells was observed with the development of technology whose
consequence was the lowering of groundwater level. To further study the
consequences, research is required to monitor the groundwater table.
31. An important subject to be studied is the villagers’ perception of groundwater. It
seems that the villagers view the problem as a matter of water flow uncertainty,
rather than as a risk of exhausting the overall groundwater storage. If the water
flow stops from one well, they drill a new replacement well with new well
designer. Thus, the drilling of wells continues and has accelerated in recent
years to ensure water supply, which will risk the sustainability of life depending
on the groundwater.
32. The cultivated area can be extended in Dakhla Oasis. However, a good management must be implemented in order to use the extracted water in a sustainably
way and prevent waterlogged areas. For example, bad positioning of the wells
leads to environmental hazards and water level decline. The main problems are
environmental threats such as salinization, not the amount of water available.
33. Further research is needed to better examine the many different problems and
good management strategies have to be done in order to realize growth in
the desert. If not, Dakhla Basin area could end with high waterlogged as an
unsustainable project.
34. Looking at the political, economic and sociological dimensions of food shortages and agricultural production would be an interesting approach to further
research into the growth of the basin and agricultural expansion in particular.
35. Waterlogging and soil salinization are the significant threat in housing and oasis
development. Extensive waterlogging could be a large threats to the development of new agricultural areas, unless the geomorphological and management
setting is recognized.
36. Detection of final future direction requires the collection of data. The data on
water management in many oases are very limited. It is very difficult to find
basic information about population numbers, land use types of agricultural use
