“…The continued growth in the number of greenhouses in the 1980s and 1990s placed a huge demand on the water supply; however, because of its underground origin, the remaining supply is difficult to measure. The impact of this demand became apparent when the quality of water from the aquifers began to show noticeable deterioration (decreased piezometric levels and increased salinization levels in coastal areas) prompting the sector to optimize and conserve its use of water (Consejería de Agricultura y Medio Ambiente, 1991;Martínez-Fernández and Esteve-Selma, 2002;Pulido-Bosch et al, 2000;Sánchez-Martos et al, 2002;Tout, 1990).…”

The arid southeast region has been one of the areas with the oldest settlement in the Iberian Peninsula. Despite limitations imposed by lack of water and low soil fertility, a great number of dwellers have settled in this land for three thousand years thanks to its easy access to the commercial paths of the Mediterranean. The area is currently under great territorial and socioeconomic transformation activated by intensive agriculture through greenhouses and irrigation. The history of this territory offers a series of successful and downward cycles determined, from an ecological and economic point of view, by its integration in different stages of the globalization process. Most recently, in the 19th century an intensive deforestation process took place caused by the mining and iron industry. The deep economic and social crisis which followed the declining of this development model brought also about an ecological crisis. In the second half of the 20th century, negative environmental effects have continued and extended to the next generations with problems such as territorial saturation and aquifer depletion that characterize the new intensive agriculture under plastic. The current debate about the sustainability of this developmental model in such vulnerable environment can take advantage of some ecological lessons from the past.

“…In recent years, several research papers concerning recharge of this aquifer system have been published (Pulido-Bosch et al, 2000;Vandenschrick et al, 2002;Alcalá et al, 2007;Frot et al, 2007;Contreras et al, 2008).…”

“…A good example is the Campo de Dalías coastal plain (Almería, SE Spain) whose deep aquifers, recharged through rainfall infiltration occurring in the Sierra de Gádor (or Gador mountain range) are overexploited for irrigation of over 26 000 ha of greenhouses (Campra et al, 2008) and the growing water demand by coastal tourism (Pulido-Bosch et al, 2000). Understanding the water balance and especially the groundwater recharge in these areas is critical to optimal management and sustainable development of groundwater resources (Taylor & Howard, 1996).…”

This paper analyses the temporal dynamics of soil water balance components in a representative recharge area of the Sierra de Gádor (Almeria, southeastern Spain) in two hydrological years. Two approaches are used to estimate daily potential recharge (PR): Approach 1 based on deriving PR from the water balance as the difference between measurements of rainfall (P) and actual evapotranspiration (E) obtained by eddy covariance; and Approach 2 with PR obtained from the dynamic pattern of the soil moisture (y) recorded at two depths in the site's thin soil (average 0.35 m thickess). For the hydrological year 2003/04, which was slightly drier than the 30-year average, E accounted for 64% of rainfall and occurred mainly in late spring and early summer. The PR estimated by Approach 1 was 181 AE 18 mm year -1 (36% of rainfall), suggesting an effective groundwater recharge in the study area. In the unusually dry hydrological year 2004/05, E was about 215 mm year -1 , close to the annual rainfall input, and allowing very little (8 AE 12 mm year -1 ) PR according to Approach 1. Estimation of PR based on Approach 2 resulted in PR rates lower than those found by Approach 1, because Approach 2 does not take into account the recharge that occurs through preferential flow pathways (cracks, joints and fissures) which were not monitored with the y probes. Moreover, using Approach 2, the PR estimates differed widely depending on the time scale considered: with daily mean y data, PR estimation was lower, especially in late spring, while y data at 30 min resolution yielded a more reliable prediction of the fraction of total PR resulting from the downward movement of soil water by gravity.Key words potential recharge; evapotranspiration; soil moisture; soil water balance; Mediterranean; Sierra de Gádor Dynamique temporelle des composantes du bilan hydrique du sol dans une chaine karstique du sud-est de l'Espagne: estimation de la recharge potentielle Résumé Ce travail analyse la dynamique temporelle des composantes du bilan hydrique du sol dans une zone de recharge représentative de la Sierra de Gador (Almeria, SE de l'Espagne) pendant deux années hydrologiques.

“…However, the lack of territorial planning in this phase of growth gave rise to increasing negative environmental externalities (over-exploitation of aquifers, accumulation of residues, etc. ), territorial congestion, deficit of public infrastructures and services and conflicts with other activities, in particular residential and tourist activities [37,38]. From the early 1990's, an environmental management was launched, and at the present time many of these problems are being solved [6,39,40].…”

Abstract:Almería is Spain's leading area for the production and exportation of vegetables. In this province we can find the largest area of greenhouses in the world, around which a major agroindustrial cluster has arisen. The present study follows a holistic approach to analyse its development and the modification of its sources of advantage. For this purpose, Porter's theoretical and analytical framework is considered. The particular natural resources of the territory were fundamental in the growth of this sector in the 1970's, allowing it to achieve absolute comparative advantages. Nowadays, the agroindustrial cluster that has built up around the greenhouse industry has enhanced the competitiveness of the sector by generating systemic and dynamic competitive advantages.
