Water resources in Spain face challenges from floods, droughts, and an imbalance between supply and demand. Reservoirs store rainwater but overuse of groundwater in coastal areas has led to salination of some wells. Northern Spain has an oceanic climate with frequent rain while southern areas have an extreme Mediterranean climate with high desertification and drought. Managing water resources successfully requires improving efficiency, avoiding contamination, sharing water fairly, and introducing new recycling technologies like desalination plants being built in the Comunidad Valenciana region to increase resources.

1. Floods & droughts

2. The water in Spain -Water is a national commodity -The balance of water is negative

3. Rivers in Spain

4. -Reservoirs store water from rain. -There are about 1300 reservoirs in Spain. -The overuse of underground water in costal areas has produced the salination of some water wells. Vilnova reservoir Barcelona (Cataluña)

5. -The recycling of water is scarce.. -Desalination provides water to the driest areas. Foix reservoir Cataluña

6. Northern Area: Oceanic Climate: ·Mild summers and cold winters. ·Many precipitations. ·High percentage of flooding.

7. Central Area: Continental Climate: ·hot summers (Droughts) ·Cold winters (freeze)

8. Southern Area: Extreme Mediterranean Climate: ·High desertification. ·Droughts during almost all the year. ·Similar climate to Morocco.

9. Eastern Area: Mediterranean climate: ·Lots of droughts. ·scars rains. ·Political problems for the repartition of water(transfers).
