Abstract. Future climate projections show higher/lower winter (Dec-Jan-Feb) precipitation in the northern/southern Mediterranean region than in present climate conditions. This paper analyzes the results of regional model simulations of the A2 and B2 scenarios, which confirm this opposite precipitation change and link it to the change of cyclone activity. The increase of the winter cyclone activity in future climate scenarios over western Europe is responsible for the larger precipitation at the northern coast of the basin, though the bulk of the change is located outside the Mediterranean region. The reduction of cyclone activity inside the Mediterranean region in future scenarios is responsible for the lower precipitation at the southern and eastern Mediterranean coast.

The Mediterranean region is an area where prediction at different timescales (subseasonal to decadal or even longer) is challenging. In order to help constrain future projections, the study of past climate is crucial. By improving our knowledge about the past and current climate, our confidence in understanding the future climate will be improved. In this Special Issue, information about long-term climate variability in the Mediterranean region is assessed, including in particular historical climatology and model applications to assess past climate variability, present climate evolution, and future climate projections. The seven articles included in this Special Issue explore observations, proxies, re-analyses, and models for assessing the main characteristics, processes, and variability of the Mediterranean climate. The temporal range of these articles not only covers a wide period going from the present day to as far back as 25 centuries into the past but also covers projections of future climate over the next century.

Beta-thalassemia is one of the most common genetic disorders among humans. It occurs in many world regions, but the highest levels are recorded in the Mediterranean countries. This study reviews the epidemiology of β-thalassemia in these countries, as well as their resources for fighting the disease, and establishes an outlook on the trends in the pathology between now and 2050. The epidemiological parameters are based on information from specialised databases, while the outlook is derived from the global population forecasts of the United Nations. With an incidence rate at birth of 15.9 cases per 100,000 newborns, the Northern coast of the Mediterranean is the least impacted and has significant health infrastructures; the number of newborns concerned could decrease by 2050. The incidence rate on the Eastern Mediterranean coast, where numerous prevention programmes are available, is twice as high, at 31.4 per 100,000 newborns; over the next 30 years, the number of new cases at birth could increase. The incidence rate on the Southern Mediterranean coast is highest, at 36.8 per 100,000 newborns, and the region continues to suffer from a shortage of health infrastructures; the number of new cases at birth could increase considerably in the region between now and 2050. These long-term projections are based on population growth in the Mediterranean countries and will be changed only by the widespread use of antenatal practices against β-thalassemia. The findings of this study could enable the countries concerned to adapt their healthcare policies.

Irrigation Requirements

Abstract. Irrigation in the Mediterranean is of vital importance for food security, employment and economic development. This study systematically assesses how climate change and increases in atmospheric CO2 concentrations may affect irrigation requirements in the Mediterranean region by 2080–2090. Future demographic change and technological improvements in irrigation systems are accounted for, as is the spread of climate forcing, warming levels and potential realization of the CO2-fertilization effect. Vegetation growth, phenology, agricultural production and irrigation water requirements and withdrawal were simulated with the process-based ecohydrological and agro-ecosystem model LPJmL after a large development that comprised the improved representation of Mediterranean crops. At present the Mediterranean region could save 35 % of water by implementing more efficient irrigation and conveyance systems. Some countries like Syria, Egypt and Turkey have higher saving potentials than others. Currently some crops, especially sugar cane and agricultural trees, consume in average more irrigation water per hectare than annual crops. Different crops show different magnitude of changes in net irrigation requirements due to climate change, being the increases most pronounced in agricultural trees. The Mediterranean area as a whole might face an increase in gross irrigation requirements between 4 and 18 % from climate change alone if irrigation systems and conveyance are not improved (2 °C global warming combined with full CO2-fertilization effect, and 5 °C global warming combined with no CO2-fertilization effect, respectively). Population growth increases these numbers to 22 and 74 %, respectively, affecting mainly the Southern and Eastern Mediterranean. However, improved irrigation technologies and conveyance systems have large water saving potentials, especially in the Eastern Mediterranean, and may be able to compensate to some degree the increases due to climate change and population growth. Both subregions would need around 35 % more water than today if they could afford some degree of modernization of irrigation and conveyance systems and benefit from the CO2-fertilization effect. Nevertheless, water scarcity might pose further challenges to the agricultural sector: Algeria, Libya, Israel, Jordan, Lebanon, Syria, Serbia, Morocco, Tunisia and Spain have a high risk of not being able to sustainably meet future irrigation water requirements in some scenarios. The results presented in this study point to the necessity of performing further research on climate-friendly agro-ecosystems in order to assess, on the one side, their degree of resilience to climate shocks, and on the other side, their adaptation potential when confronted with higher temperatures and changes in water availability.

Antimicrobial resistance has become a global threat to effective health care delivery. This is particularly the case within the Mediterranean region, where data from recent studies suggests the situation to be particularly acute. A better knowledge base, as well as a collaborative effort, is therefore required to address this ever increasing challenge to effective patient care. Over its four-year period, the Antibiotic Resistance Surveillance and Control in the Mediterranean Region (ARMed) project investigated the epidemiology of antimicrobial resistance, as well as its contributory factors, in a number of countries in the southern and eastern Mediterranean region through the collection of comparable and validated data. The project culminated in a consensus conference held in Malta in November 2006. The conference provided a forum for expert delegates to agree on a number of priority strategic recommendations that would be relevant to resistance containment efforts in the region. There was general agreement on the need for surveillance and audit to underpin any intervention to tackle antimicrobial resistance, both to monitor changing epidemiological trends in critical pathogens as well as to identify antibiotic consumption practices and effectiveness of prevention and control of health care associated infections. In addition, the importance to convey these data to key users was also stressed in all workshops, as was better education and training of health care workers. The recommendations also made it clear that ownership of the problem needs to be improved throughout the region and that resources, both financial as well as human, must be allocated by the respective policy makers in order to combat it.

：In intensively managed watersheds, water scarcity is a product of interactions between complex biophysical processes and human activities. Understanding how intensively managed watersheds respond to climate change requires modeling these coupled processes. One challenge in assessing the response of these watersheds to climate change lies in adequately capturing the trends and variability of future climates. Here we combine a stochastic weather generator together with future projections of climate change to efficiently create a large ensemble of daily weather for three climate scenarios, reflecting recent past and two future climate scenarios. With a previously developed model that captures rainfall-runoff processes and the redistribution of water according to declared water rights, we use these large ensembles to evaluate how future climate change may impact satisfied and unsatisfied irrigation throughout the study area, the Treasure Valley in Southwest Idaho, USA. The numerical experiments quantify the changing rate of allocated and unsatisfied irrigation amount and reveal that the projected temperature increase more significantly influences allocated and unsatisfied irrigation amounts than precipitation changes. The scenarios identify spatially distinct regions in the study area that are at greater risk of the occurrence of unsatisfied irrigation. This study demonstrates how combining stochastic weather generators and future climate projections can support efforts to assess future risks of negative water resource outcomes. It also allows identification of regions in the study area that may be less suitable for irrigated agriculture in future decades, potentially benefiting planners and managers.

A key element in the product mix of destinations is climate. Climate represents a critical part of a destination’s economic and resource base such that changes in climate will trigger human responses in terms of demand and the type of activities that the climate will support. This threatens the competitiveness, sustainability, and economic viability of destinations. This research note focuses on destination adaptation to climate change that is anticipatory not reactive, based on projecting future climate scenarios for a destination and then assessing the tourism products that the future climate will support. It outlines an original data-driven approach to adaptation that is generalizable to other destinations. The research note describes an exploratory research collaboration in Croatia between tourism and climate scientists that allows, first, the modeling of a destination’s projected climate conditions and, second, the products and activities that can be supported by these climate scenarios using climate indices for tourism.

A survey of the members of the genus Clubiona Latreille, 1904 in the Maghreb is presented. The presence of Clubiona comta C. L. Koch, 1839, C. dinienis Simon, 1878, C. leucaspis Simon, 1932, C. phragmitis C. L. Koch 1843 and C. vegeta Simon, 1918 is confirmed. Clubiona pseudosimilis Mikhailov, 1990, from the eastern Mediterranean is new to Africa and Portugal. A specimen of C. neglecta O. Pickard-Cambridge, 1862, cited from Morocco in the past, was misidentified and appears to be C. pseudoneglecta Wunderlich, 1994. The species is new to Algeria and Spain. Two new synonyms are revealed: Clubiona baborensis Denis, 1937 from Algeria = C. diniensis Simon, 1878 N. Syn. and Clubiona venusta Pavesi, 1880 from Tunisia = Selamia reticulata (Simon, 1870) N. Syn. Clubiona mandibularis Lucas, 1846 is considered a Nomen dubium. The comta group is redefined and the “genevensis subgroup” is elevated to species group, including two subgroups. A key and illustrations to the species of the genevensis group are presented and all the species occurring in the Maghreb are illustrated.

Impacts Of Climate Change

Abstract In this paper, two approaches to assess the impacts of climate change on streamflows have been used. In the first approach (direct), a statistical downscaling technique was utilized to predict future streamflows based on large-scale data of general circulation models (GCMs). In the second approach (indirect), GCM outputs were downscaled to produce local climate conditions which were then used as inputs to a hydrological simulation model. In this article, some data-mining methods such as model-tree, multivariate adaptive regression splines and group method of data handling were utilized for direct downscaling of streamflows. Projections of HadCM3 model for A2 and B2 SRES scenarios were also used to simulate future climate conditions. These evaluations were done over three sub-basins of Karkheh River basin in southwest Iran. To achieve a comprehensive assessment, a global uncertainty assessment method was used to evaluate the results of the models. The results indicated that despite simplifications included in the direct downscaling, this approach is accurate enough to be used for assessing climate change impacts on streamflows without computational efforts of hydrological modeling. Furthermore, comparing future climate projections, the uncertainty associated with elimination of hydrological modeling is estimated to be high.
