Until 20 years ago, an important part of Timi? County was affected by humidity excess of different types. As a consequence were designed and installed many drainage arrangements which worked intensive, during the drought periods being created perfect conditions for most of the crops. Between 1990 and 2000 the situation has changed. The climatic changes together with the significant decrease of water table (result of intensive drainage) impose in the drought periods to be applied irrigation in order to assure proper conditions for agriculture. The combination intensive drainage - climate heating presents negative impact and upon wetlands. The water deficit encouraged a fast mudding which generated the possibility of open water surfaces by vegetation and the water quality degradation. The impacts are visible upon trophic chains. In the last years and nowadays, it seems that precipitations are presenting again a tendency of increasing in volumes which generate often inundations. The book will present the situation in Timi? County regarding humidity excess and water scarcity and will also debate problems regarding the wetlands future.
