La regione Puglia presenta distinti contesti geologici, ciascuno caratterizzato da evoluzioni morfologiche che, a causa della elevata antropizzazione del territorio, inducono differenti condizioni di propensione al dissesto idrogeologico. Tra queste, data la natura prevalentemente carbonatica delle rocce affioranti, i fenomeni di subsidenza carsica e di sprofondamento hanno un ruolo notevole.
Le fasce costiere adriatica e ionica della Puglia centro-meridionale sono sovente costituite da pianori carsici, elevati pochi metri sul mare, ed estesi da alcune centinaia di metri sino a qualche chilometro verso l'entroterra. Calcareniti del Pliocene e del Pleistocene costituiscono acquiferi costieri con diffuse manifestazioni sorgentizie, sede di accentuati fenomeni ipercarsici. I pianori sono caratterizzati da varie forme carsiche epigee tra cui numerose doline di crollo.
Il frequente manifestarsi, anche alla scala umana, di fenomeni di sinkhole di tipo carsico e la loro interazione con l'ambiente antropizzato (edifici, infrastrutture viarie, linee di servizi) ha reso necessario l'approfondimento di queste tematiche ai fini della mitigazione dei rischi ad esse connessi.
La zona paludosa delle Cesine è un'area naturalistica di notevole interesse, dichiarata Zona Umida di interesse internazionale. Sita sul litorale adriatico, a poca distanza da Lecce, quest'area è fortemente interessata da fenomeni di subsidenza carsica. Essendo quasi interamente coperta da vegetazione, risulta però pressoché impossibile monitorarne gli sprofondamenti. Infatti l'effetto di questi, ed in particolare la formazione di aree prive di vegetazione con forma circolare o ellittica, risulta visibile soltanto per brevi periodi, prima che la ricrescita delle piante, a cominciare da quelle idrofile, ne mascheri rapidamente la presenza.
Le paludi e lagune delle Cesine sono considerate specchi d'acqua retrodunali. In realtà non si hanno elementi oggettivi per dimostrare l'origine degli invasi d'acqua quale effetto dello sbarramento verso mare alle acque interne operato da cordoni di dune. Gli studi geologici, carsici ed idrogeologici condotti dagli scriventi hanno consentito la ricostruzione del seguente modello di formazione_ dalla coalescenza di più singole doline originarie si formano depressioni estese sino a migliaia di metri quadri, che sono separate dal mare da diaframmi di roccia calcarea instabile e intensamente carsificata, il cui collasso può provocare la formazione di veri e propri canali costieri. Laddove la coalescenza delle doline avvenga secondo sistemi di fratture trasversali alla costa, tali fenomeni determineranno la formazione di insenature.
Come precedentemente accennato, il verificarsi di fenomeni di sprofondamento sul territorio pugliese può avere ripercussioni anche sull'ambiente antropizzato. Un significativo esempio in tal senso è costituito dall'abitato di Casalabate, pochi chilometri a nord dell'area delle Cesine, che è stato ripetutamente interessato negli ultimi 15 anni da fenomeni di dissesto. Il primo di due eventi avvenuti nel 1993, ad esempio, ha avuto le maggiori conseguenze sul patrimonio edilizio_ la formazione di una dolina ha infatti dapprima determinato la distruzione di due edifici; in seguito le lesioni si sono propagate a numerosi edifici contigui, peraltro realizzati con scarsa attenzione rispetto alle interazioni con il sottosuolo. Nell'arco di alcuni mesi sono stati dichiarati pericolanti decine di abitazioni, poi completamente demolite. Tra i più recenti eventi in quest'area si ricorda quello del 2000, allorquando si formò una dolina in prossimità della battigia, in breve colmata dalle sabbie litorali.

Karst environments are particularly susceptible to negative impacts from human activities, due to a number of geological, morphological and hydrogeological features. The intimate connection between surface and underground drainage, and the rapidity with which surface water (and the potential contaminants as well) may enter and percolate
down through the carbonate rocks, result in an overall fragility of the karst landscape, and in high vulnerability of the karst aquifers. The present contribution describes a
case study in the Salento Peninsula (Apulian karst of southern Italy): the Burgesi area has been intensely used to quarry limestones, and later on become site of several illegal landfills where solid and liquid wastes were dumped, with serious consequences for the groundwater resources. In the very flat landscape of the study area, the most
typical karst feature is represented by dolines with a well-defined circular shape, deep less than 10 meters. They can be mostly considered as collapse dolines, being originated from sinking of vault caves. Some of them were originally filled, usually for most of their depth, by residual soils, but these materials have been extracted in the
past, and the initial landform consequently changed. Heavy changes occurred in fact in the last years because of anthropogenic activities such as stone clearing, removal
of the soil cover, and intense quarrying activities. Multi-year aerial photo interpretation, integrated with recent field surveys, allowed to assess the areal distribution of
the quarrying activity during the last 30 years. Besides quarrying activity, further serious environmental problems occurred when the sites began to be used to dump solid
and liquid wastes. Since 1980, several episodes of pollution had to be registered, the most serious of which consisted in heaping in the quarries of some hundreds of drums
containing highly contaminated waste industrial oils. The possibility of ground water contamination at Burgesi has been analysed by considering a number of factors,
including the characteristics of the landscape, the unsaturated (vadose) zone and the aquifer (or saturated zone). To evaluate the impacts of quarrying stones on the aquifer vulnerability, two levels of geological analyses have been performed. The first coincides essentially with the assessment of the pollution potential, that is the intrinsic
vulnerability of ground water at the site. The second level consists of detailed geological mapping addressed at the identification of stratigraphy, tectonic features, and
surface and underground karst landforms. In addition, this second level of geological analysis represents an attempt toward evaluation of the more likely propagation of polluting substances by means of a combination of real observations and characteristics of the karst system. A significant increase in the intrinsic vulnerability of the aquifer as a consequence of the quarrying activity has been assessed. Nevertheless, fast drainage from the landscape to the aquifers through discontinuities in the rock mass, and development of karst systems can be hypothesized. As a consequence, pollutants may be drained from the ground surface to the aquifers in a very short time. This paper intends to remark the high fragility of karst and the need to correctly manage such environment, aimed at the preservation of the natural landscape and of the quality of karst aquifers.

The Apulia Platform is a thousands meters thick Cretaceous carbonate sequence which, since the Oligocene, became the foreland of the Southern Apenninic Chain
of Italy. During the early Pleistocene, the Apulian Foreland was dissected by direct faulting into horsts and grabens; this structural setting produced the establishment
of a shallow marine carbonate environment. As a consequence, carbonate deposits started to be deposited and to cover shore platforms around, and on top of, the horsts.
Later on, the Apennine Chain and the central sector of the foreland, the Murge Highplains, emerged due to uplifting of the area, whilst the edifice of Mount Vulture began
its volcanic activity. Eventually, during the middle and the late Pleistocene, Apulia was brought to its present conformation. The area around the town of Ostuni, in the
southeastern Murge, is intensely affected by karst processes which resulted in the formation of some tens of karst caves. Many of these are of remarkable importance for
the palaeoethnology and the archaeology of the Mediterranean basin, since several remains have been found therein. To provide an example, the cave at S. Maria di Agnano hosted three Upper Paleolithic (Gravettian) burials; one of these (named Ostuni 1) is a pregnant woman preserving almost all the fetal remains, which makes it an
extraordinary discovery. History of the occupations of the karst caves in the Ostuni territory, integrated by geological, morphological and karst data, may provide useful
information for the palaeoenvironmental and palaeoecological reconstruction during the Quaternary in southern Italy. The mixed volcaniclastic-carbonate deposits which
are the object of this study have been found near the cave of S. Maria di Agnano, overlying the Cretaceous carbonate bedrock where the cave opens. The deposits are
little cemented and strong weakened. The volcanic materials are mainly represented by pumice, scoria, feldspar, feldspathoid and pyroxene. The petrography features of
the grains suggest a volcanic activity contemporaneous to the sedimentation of deposits.
Besides the volcanic materials, shells of benthonic forms, and particularly of gastropods and bivalves, are very common in the deposits. Shells are generally intact
and very abundant, especially as regards the smallest exemplars. Whitish soft nodules (probably calcium sulphate-carbonates) are also present. Sedimentology and stratigraphy of the deposits cropping out along the Agnano slope have to be examined taking into account also further elements_ among these, the Quaternary sea level changes in the area, the resulting effects on the karst caves, and the presence of other deposits, starting from eolianites on nearby slopes. The latter, entirely consisting of carbonate grains, are referred to the early Pleistocene and do not contain any volcanic materials.
This paper presents some preliminary considerations on the mixed volcaniclasticcarbonate deposits, in the attempt to include them within the framework of the overall
geological and palaeogeographical setting of the Ostuni area. Based upon the data so far collected, the mixed deposits might be referred to the end of the early Pleistocene
or, more probably, to the middle Pleistocene, and would represent littoral shelf (nearshore) facies, with contribution of volcanic materials likely deriving from the
activity of Monte Vulture.

Abstract
The Apulia region of southern Italy is one of the most important italian karst areas, ...
The Apulia region of southern Italy is one of the most important italian karst areas, due to widespread presence of carbonate rocks over its entire extension. Surface and
subsurface karst morphologies characterize it, with particular diffusion of landforms as dolines and sinkholes. Since the first occupation of this land by man, some of the
karst landforms have been used and partly modified (if not cancelled) to several aims_ draining the surface waters, discharging floods, and reclaiming marsh lands, among
the others. Southern Apulia, in particolar, hosts a large number of dolines, producing at the ground similar morphologies (abrupt shafts in a generally flat terrain) but
which might be originated by different processes (collapse, solution, soffusion, etc.).
This contribution examines the territory of Mesagne, in the Brindisi province_ even if characterized by mostly flatland, the Mesagne area presents some tens of water
sinks, most of which correspond to dolines. Drainage works today visible at the sites derive from a multi-secular anthropogenic activity. Some of the dolines have been
recognized as produced by collapse, through progressive detachment of the vault of an original underground cavern, or favoured by the erosion of low cemented sandy
and silty deposits covering the underlying carbonate rocks. Likely, many other dolines might share the same origin. At Mesagne, as in large areas of Salento (the southern
part of Apulia), a Quaternary sequence transgressively overlies the Cretaceous carbonate bedrock with an unconformable contact. The Quaternary sequence consists of
calcarenites and intervening clayey deposits. The bottom calcarenite can be correlated to the Pleistocene Calcarenite di Gravina formation; above it, an intermediate unit,
made of argillaceous silts with sandy intercalations, is present. The top unit is again formed by calcarenites with subordinate calcirudites, related to the Terraced Marine
Deposits Auct. Due to this geological configuration, the hydrogeology of the area shows two distinct aquifers_ the shallow aquifer is represented by the top calcarenites.
Water from this aquifer is generally used for irrigation. The aquifer lower limit is given by the impervious layers in the argillaceous silts, which act as a barrier of low
permeability. The deep aquifer, on the other hand, is contained within the Cretaceous limestones, and represents the only local supply of drinkable water. From the hydrogeological point of view, the territory of Mesagne, which is considered as representative of large areas in southern Apulia, is highly vulnerable to the following hazards_ (i)flooding, favoured by the overall flat topography, and the presence of geological formations with low permeability in the first meters of the subsoil; (ii)development of collapse dolines, or sinkholes; (iii) groundwater pollution, regarding both the shallow and the deep aquifer. Safeguard of the hydric resources, and mitigation of the risk related to natural and anthropogenic hazards in this fragile karst area, may be pursued only through knowledge of the physical features of the territory and the correct management of its natural resources.

Desertification, as it has been defined by the United Nations
Convention to Combat Desertification (UNCCD), represents the whole
phenomena of land degradation, resulting from many causes. Southern
European countries are considered as areas of new expansion of desertification,
caused by inadequate agricultural practices, overgrazing, and deforestation,
which increase anthrophic pressure. During the last few years, in the
context of several international research projects, methodologies were
proposed, based on various parameters. These are grouped in uniform classes
and weighted by the attribution of scores in order to assess the so-called
"quality indexes". By computation of the previous indexes, "desertification
indicators" are defined. This work reviews the most-used methodologies and
presents an application of the methodology proposed in the European
MEDALUS project to an area of the Calabrian territory (southern Italy),
relative to the physical aspects
