presentada en Sevilla el 10 de Diciembre de 2014. de Sevilla[EN]: The world's population is 7 billion and will surpass 9 billion in 2050, which will lead to an increased demand for food. The total land area includes marginal land, such as deserts, steep mountains, swamps, and formerly arable areas that have been degraded after unsustainable land use. The present study focuses on land
degradation and potential agricultural productivity in different Mediterranean areas: Andalusia (southwestern Spain) and El-Fayoum (northern Egypt). These areas were chosen to study soil contamination, erosion and suitability of different land uses, and to produce recommendations to preserve productive arable land,
which is a scarce resource.[ES]: La población mundial actual es de unos siete mil millones y superará los nueve mil millones en 2050. Se espera que esto conduzca a un aumento de la demanda de alimentos. El área total de la superficie terrestre incluye tierras marginales o no aptas para el cultivo, tales como desiertos, montañas escarpadas, pantanos, al igual que zonas anteriormente cultivadas que han sido degradadas como consecuencia de un manejo inapropiado. El presente estudio se centra en el análisis de la degradación del suelo y el potencial agrícola en dos zonas del Mediterráneo: Andalucía (suroeste de España) y El-Fayoum (norte de Egipto). Estas áreas zonas fueron escogidas para estudiar los procesos de contaminación, erosión del suelo y su capacidad para diferentes usos, y, finalmente, llevar a cabo recomendaciones orientadas a la conservación de la tierra cultivable como un recurso no renovable.This PhD thesis has been funded by the Spanish Agency of International Cooperation for Development (AECID), a public law entity under the Spanish Ministry of Foreign Affairs and Cooperation.Peer reviewe
Agro-Ecological soil evaluation for monitoring water quality using MicroLeis DSS.
Soil degradation has both indirect and direct effects on the quality of surface and ground waters. In this sense, agriculture is one of the key activities causing water quality degradation in many parts of Mediterranean systems. In the European Union, the purpose of the Water Framework Directive (European Commission, 2000) is to establish a framework for the protection of inland surface, transitional, coastal and ground waters too. A major source of surface and ground water pollution is the diffuse contamination caused by nitrates in agricultural lands. This specific water protection was regulated by the Nitrates Directive (ND, 1991/676/EC), which in Spain was developed by a Royal Decree (261/1996/BOE), and in Andalusia region by a Decree (36/2008/BOJA) for the designation of water quality vulnerability zones (22 zones) and an Order of the Regional Government of Andalusia (18.11.2008/BOJA) to establish the action programs (1 unique program) to be implemented by farmers. However, the Nitrates Directive considers that different action programs may be established for different vulnerable zones or parts of those areas. Also, these action programs must take into account scientific and technical information that are available on each particular soil and climatic conditions, such as rainfall erosivity, length of the growing season, slope, soil infiltration and soil denitrification capacity. Within this context, the agro-ecological decision support system MicroLEIS DSS (technology developed by CSIC-IRNAS and transferred to Evenor-Tech, www.evenor-tech.com) is considered a very appropriate tool to include the soil and climatic attributes for a better identification of vulnerable zones and formulation of action programs. In this paper, the MicroLEIS DSS modelling infrastructure to predict soil erosion and contamination risks (ImpelERO and Pantanal models, basically) is discussed, as a scientific approach to identify detailed vulnerable areas, and formulate site-specific management plans for sustainable water use and protection in Andalusia region. The high variability of the results from this agro-ecological land evaluation research in Water Quality Vulnerability Zones demonstrates the importance of using soil information in decision-making regarding the formulation of site-specific soil use and management strategies.Peer Reviewe

Forest land suitability in a Mediterranean area under climate change scenarios
Comunicación oral presentada al citado congreso, celebrado del 7-12, abril, 2013, en Viena, Austria.-- Sesión: SSS9.2: Studiying soils and/or land: Approaches for sustainable management of the environment.As a consequence of the increasing level of atmospheric CO2 and air temperatures, global climate is changing
leading to warmer and often drier conditions in many forest ecosystems. The Mediterranean area is particularly
vulnerable to climate change as a result of a combination of environmental and human factors. An adequate forest
management is associated to improvement of habitat suitability for soil and water quality, climate regulation and
other important ecosystem services.Peer reviewe
Evaluating impact of climate change on soil quality indicators in the Mediterrnean region
More reliable quantification of the impact of climate-change on soil quality and its ecosystem services is required
to adapt patterns of yield and productivity, forest management, and resource availability. In this context, the present
study evaluates the effects of climate change on agriculture soil and forest capacity as well as on its vulnerability
to degradation process like erosion and soil contamination, in the Mediterranean region of Andalusia (S, Spain).Peer reviewe

Evaluating soil degradation under different scenarios of agricultural land management in Mediterranean region
14 pages, 9 figures, 7 tables, 30 references.In this research work the Agro-Ecological Decision Support System MicroLEIS DSS, was applied to evaluate land degradation under different scenarios of land management. El-Fayoum depression was selected as a pilot area, this is one of the western desert depressions in the Arab Republic of Egypt. The area offers a great potential for agriculture using water from the river Nile. The main objective is to investigate and predict the risk of soil contamination for phosphorus, nitrogen, heavy metals and pesticides under traditional and recommended management scenarios of maize cultivation. The following components of MicroLEIS DSS have been used: 1) soil database (SDBm), 2) agro-climate database (CDBm), 3) agricultural management database (MDBm), and 4) the specific assessment model for the vulnerability of soil contamination called “Pantanal”. Then, a recommended scenario based on different land management has been produced for maize crop, which aimed to reduce soil contamination vulnerability of phosphorus, nitrogen, heavy metals and pesticides. The model application results are grouped in five vulnerability classes: V1 (none), V2 (low), V3 (moderate), V4 (high) and V5 (extreme) for each specific contaminant. Results obtained for El-Fayoum area showed that 47.8% and 52.2% of total studied area were classified as V3 and V4 vulnerable land due to phosphorus contamination under the traditional management scenario, but 41.9%5.9% and 52% of total area were classified as V2, V3 and V4 because of the same contaminate under recommended management scenario. On the other hand, 98.7% and 1.3% of the total area were classified as V3 and V4 vulnerable land due to nitrogen and heavy metals under the traditional management scenario, however in the other recommended scenario 94.0% and 5.6% were classified as V1 and V2 classes due to nitrogen contaminate and 79.0%, 19.1% and 1.7% were classified as V1, V2 and V4 for heavy metals contaminates. In the same trend 2.6%, 8.1%, 17.4% and 91.7% were classified as V1, V3, V4 and V5 due to pesticides contamination in the actual management scenario, however 24.0% and 76.0% were classified as V1 and V2 respectively due to the same contaminant under the recommended management scenario. In summary, we can ensure that these innovative agro-ecological studies such as those developed by MicroLEIS DSS can be applied and adapted in the agricultural provinces of Egypt in order to achieve a national sustainable rural managementPeer reviewe
