Along with being a dynamic process that affects large areas, desertification is also one of the most serious problems in many countries. The effects this phenomenon threaten sustainability natural resources, namely water agricultural production and major basic infrastructure, specifically roads habitations. Several factors exacerbate such as climate dryness, geological morphological characteristics terrain, irrational use space, population growth over-exploitation vegetation resources. This...

Sustainable natural resources management relies on effective and timely assessment of conservation land practices. Using satellite imagery for Earth observation has become essential monitoring cover/land use (LCLU) changes identifying critical areas conserving biodiversity. Remote Sensing (RS) datasets are often quite large require tremendous computing power to process. The emergence cloud-based techniques presents a powerful avenue overcome limitations by allowing machine-learning...

Erosion is the main threat to sustainable water and soil management in Morocco. Located Souss-Massa watershed, rural municipality of El Faid remains an area where gully erosion a major factor involved degradation flooding. The aim this study predict spatial distribution at scale evaluate predictive capacity three prediction methods (frequency ratio (FR), logistic regression (LR), random forest (RF)) for characterization gullying vulnerability. Twelve predisposing factors underlying formation...

Oued El Maleh watershed is considered the largest ocean basin of Chaouia-Ouardigha region in Morocco. Severe flooding occurred 1996, 2001 and 2002 watershed. Thus, significant economic human damage has been caused. The floods Mohammedia city, located outlet watershed, were due to silting dam which lost its ability retain water. This work, therefore, aims assess soil losses by water erosion through modeling main factors involved erosion. methodology used based on use universal loss equation...

Le changement climatique constitue un grand défi à relever par les politiques publiques et gestionnaires des espaces naturels. La compréhension de ses impacts sur écosystèmes forestiers préalable nécessaire toute réflexion visant leur conservation le maintien services écosystémiques qu’ils offrent. Cette étude s’est intéressée la modélisation distribution potentielle Cedrus atlantica Manetti, l’identification variables environnementales conditionnant sa distribution, définition l’étendue...

Unmanaged livestock grazing is the greatest threat to health and sustainability of forest rangelands in Morocco. Historically, communities have developed ingenious traditional systems order regulate natural resource uses. However, currently most these principles been undermined led open access a common pool resource. To achieve viable solutions unmanaged forestlands, local community involvement was introduced Moroccan forestry early on. The main objective this study show importance an...

Climate change, which is expected to continue in the future, increasingly becoming a major concern affecting many components of biodiversity and human society. Understanding its impacts on forest ecosystems essential for undertaking long-term management conservation strategies. This study was focused modeling potential distribution Quercus suber Maamora Forest, world’s largest lowland cork oak forest, under actual future climate conditions identifying environmental factors associated with...

Maamora is considered the most important cork-oak forest in world with regard to surface. Therefore, anthropic pressure, including cork harvesting, grazing and soft acorn picking up by local communities, has harmful consequences on regeneration become older exceeding harvesting age. Thus, its sustainability depends managers' ability succeed oak plantations. This work presents an assessment approach evaluate Quercus suber suitability plantation which based a random algorithm (RF). In fact,...

La conservation et la gestion des espèces endémiques, impose connaissance de leurs aires distribution potentielle facteurs environnementaux conditionnant ces répartitions. Ce travail vise l’identification écologiques régissant répartition géographique d’Argania spinosa cartographie son aire sous les conditions climatiques actuelles ce, pour une meilleure planification sa gestion. L’approche d’entropie maximale a été utilisée. Le principal résultat est carte probabilité continue montrant...

Following the assumption that some soils are less suitable for development of cork oak, a substitution oak by exotic species has been carried out on large part Maamora forest.However, soil is not only factor to consider in assessing suitability.Therefore, areas might just suit but what extent?To answer this question, major factors known influence regeneration have identified and mapped using multicriteria evaluation.Therefore, were incorporated weighted linear combination determine...

This work aims to present an efficient and practical method mapping rosemary cover, which belongs esparto grasslands. The approach consists of merging tow technics: remote sensing machine learning. At first, three indices, normalized differenced vegetation index (NDVI), water (NDWI), soil adjusted (SAVI), were calculated using Sentinel 2A MSI image clipped for the study area. In a second place, set terrain truth samples was used train model. end, model classify RGB built with spectral...

To assess the degree to which it has met its commitments under Paris Agreement, Morocco is called upon carry out carbon assessments and transparent evaluations. Within forestry sector, little known about role of Morocco’s forests in contributing uptake. With this aim, we applied for first time literature 3-PG model Cedrus atlantica ((Endl.) Manetti ex Carrière, 1855), represents 131,800 ha forest area (i.e., Azrou forest). Through Differential Evolution-Markov Chains (DE-MC) tested assessed...

Abstract Global warming is becoming a major concern affecting many components of the biodiversity at global scale and disproportionately integrity ecosystems, particularly habitat endemic species. Understanding its impacts on most vulnerable species essential to improve knowledge ecology these for their long-term management conservation. Abies marocana Trabut (Moroccan fir), remarkable forest tree Mediterranean basin, an endangered that present in discreet small areas Rif Mountains, which...

Factors determining forest species distribution include, in addition to external factors such as human interference and environmental management strategies, also soil hydrological characteristics climate conditions any given areas. Modelling<strong> </strong>distribution has practical application conservation management, help decision makers develop strategies aimed at restoration, development of mountainous areas the continuous sustainable provision forest-related services....

La Mâamora est une importante subéraie (forêt de chênes-lièges) du littoral marocain. Théâtre multiples infractions et objet convoitises, la forêt chênes-lièges a été choisie pour réalisation d'un projet relatif aux biens services écologiques. Elle constitue ainsi un terrain d'expérimentations axées sur participation population locale à gestion forestière. Dans cette perspective, mécanisme Compensation Mise en défens (CMD) comme des partenariats entre l'administration coopératives...

North African forest areas play several roles and functions represent a heritage of great economic ecological importance. As result global changes, that act independently or synergistically, these are currently undergoing pronounced degradation their productivity is decreasing due to factors. This work aims characterize spatio-temporal dynamics vegetation within the Maamora forest. considered as most extensive cork oak woodland in world divided, from west east, into five cantons A, B, C, D...

Erosion affects large parts of Moroccan land, particularly in the mountains leading to soil quality deterioration and less vegetation cover.Located South-west Morocco, Site Biological Ecological Interest (SBEI) Ain Asmama, where erosion threatens a major part region was investigated.The site has terraced transitional bioclimate, between arid sub-humid, local conservation importance.The varied, dense, continuous, well-preserved area is crucial protect soils against erosion.Qualitative...

Abstract Background Harvested wood products (HWPs) have a pivotal role in climate change mitigation, recognition solidified many Nationally Determined Contributions (NDCs) under the Paris Agreement. Integrating HWPs’ greenhouse gas (GHG) emissions and removals into accounting requirements relies on typical decision-oriented tools known as product models (WPMs). The study introduces ‘TimberTracer’ (TT) framework, designed to simulate HWP carbon stock, substitution effects, from decay...
