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...

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...

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...

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...

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...

The concept of ecosystem services (ES) is increasingly used to analyze the relationships and interactions between humans nature. Understanding services’ flow ecosystems’ capacity generate these an essential element in considering sustainability uses development accounts. For such purpose, we conduct spatially explicit analyses nine Maamora forest, Morocco. included are timber industry wood harvest, firewood cork gathering, forage production, acorn forest carbon storage, recreational hiking....

Assessment of land cover dynamics in the Tahaddart Ramsar wetland (North-western Morocco). Land and dynamics, both time space, were analysed (Northern Morocco) to determine evolution environmental quality this Site Biological Ecological Interest (since 1996), also classified as a site 2005). Remote sensing was used estimate impact use changes on natural habitats over 35-year period from 1978 2013. The first image MSS captures with spatial resolution 80 m. improved since 1991 Landsat 4...

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...

Forest resources in the Ourika watershed are subject to several anthropogenic and climatic degradation factors. As for human factor, this of forest is explained by bad practices exercised local population expressed cutting live wood, carbonization, overgrazing. In terms decrease amount rainfall increase temperature contribute exacerbation these resources. order better understand evolution plant cover a changing climate context, study highlights an assessment impact change on dynamics based...

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...

Mapping of fire intensity and sensibility to crown fires in Mediterranean forests. Case the province Chefchaouen northern Morocco. The current evolution forest regime poses new challenges usual practices management plans strategies. implementation wisely measured actions on ground terms preventive silviculture, water points or breaks, requires a deep understanding fine mapping behaviour. This paper focuses first using Byram formula Chefchaouen, one most affected regions by this scourge speed...

Water erosion causes significant economic losses linked mainly to the silting up of dams and in soil productivity, these consequences will increase if water conservation actions associated with development are not undertaken. The present work aims evaluate basin Beni Boufrah located Northern part Morocco. hierarchy this plot according degrees tendencies was made using qualitative PAP/CAR approach (Programme d’Actions Prioritaires/Centre d’Activités Regionales) which is based on integration...

Abstract The North African steppe areas represent a heritage of great economic and ecological importance. These areas, which were once prosperous, are currently experiencing significant degradation decrease in productivity due to several factors. objective this study was evaluate the dynamics vegetation, identify responsible factors, present perspectives for their management restoration. methodological approach adopted characterization climatic socioeconomic conditions analysis vegetation...
