The fight against water shortage must be strengthened .At the end of the hydrological year on 30 September 2005, resulted that the rivers had significantly reduced its flow, transfers were insufficient, the average reserve of the country’s reservoirs were about 40%, 21000 hectometres cubic, with the lowest values of reserve for the basins of Segura, Jucar, Cataluña and the South, with a cumulative total of just 1254 hectometres cubic, which puts the Mediterranean area as the area of lowest water reservation of Spain. The groundwater dry Spain being operated on, which results in an high abatement of the water table and a decrease in the flow of delivery of the wells, so we need a systematic control of flow and water quality The desalination only solved problems of water needs in certain areas, hard to ensure the demands of water demand, users have not been able to meet in full the water needs, but with limitations.
The ravages of drought have already caused losses of billions of euros and still growing, we must prepare for the future and develop a plan of action in the short and long term that will allow the construction of more dams, works regulators, transfers, waterworks, and recharging aquifer. , which are capable of regulating runoff in times of abundance, to ensure more usable water in the dry season. The action plan must be to run in three ways: we can do it with the resources of the autonomous region, with supports the Spanish government and the received of European Union aid. The waterworks to run for immediate action, proactive and coordinated because of prolonged drought long lead indebtedness of the agricultural sector, will be the problems with the water supply to the population, industry and trade, increase the cost in life, create problems in the Public Health by the emergence of diseases such as diarrhoea, typhoid and cholera, which may also appear in flooded areas.
It also should be a greater effort in the treatment of domestic and industrial discharges and reuse of wastewater in crops that allow its use because the increase in population and industrial development made that wastewater will be an additional source of water.
The fight against flooding is an activity that must also prioritized, it is not necessary to wait until there are heavy losses as a result of heavy flooding to make decision-making in the fight against water excessive, we think that long-term cost of investment to execute will be minors than human and material losses caused by floods and maximum flow. In Spain floods represent a great danger and have a devastating effect, mainly in the Mediterranean dimension where there are areas with precipitation higher than 250 mm in 2 4 hours. The warning system and hydrological forecasts allow for a more efficient defence against flooding, which in conjunction with the inventory of flooded areas and areas with drainage problems, make possible made to plan that we must protect areas in the short term and which in the long term. Damage to the people, crops and different sectors of the economy as a result of the flood have a social and economic character that we interrelate to the assessment of areas that are going to protect and what kind of work we are going to do. The adequacy of the basin, the protection and cleaning of rivers, the rectification of rivers, construction of protective dikes, dams, drainage systems in the agricultural, reforestation and planting crops covering a most soil, are mechanisms for combating floods and avenues. The fight against drought and flooding should be treated as an integral problem, it is necessary to undertake a country hydraulic development plan which involves more investment, more solutions water, create new infrastructure and to schedule a plan of action against floods.
