In semi-arid areas, many ecosystems and activities depend essentially on water availability. Morocco, the increase of demands combined to climate change induced decrease precipitation put a lot pressure groundwater. This paper reports results updating evaluation groundwater datasets with regards scenarios institutional choices. The continuous imbalance between extraction recharge caused dramatic decline in levels (20 65 m past 30 years). Additionally, Morocco suffers from degradation quality...
ABSTRACT A new fossil record from the southern Middle Atlas spans continuously last 25 000 years and provides evidence of an increased amount snow precipitation during glacial period a warm early Holocene with rather dry climate conditions. This environmental reconstruction is based on multi‐proxy approach that integrates pollen, micro‐charcoals, grain size geochemical analysis. During we observe strong presence aquatic plants species today flower late spring summer. These occurrences are...
Abstract Pollen and organic-walled dinoflagellate cyst assemblages from core GeoB 9503-5 retrieved the mud-belt (∼ 50 m water depth) off Senegal River mouth have been analyzed to reconstruct short-term palaeoceanographic palaeoenvironmental changes in subtropical NW Africa during time interval ca. 4200 1200 cal yr BP. Our study emphasizes significant coeval continental oceanic environments shows that initial dry conditions were followed by a strong rapid increase humidity between 2900 2500...
Abstract Terrestrial signals in marine sediment archives are often used for paleoclimatic reconstructions. It is therefore important to know the origin of different terrestrial sedimentary components. The proximity a river mouth key location determine source. Especially regions with strong ocean currents, such an assumption might, however, lead considerable misinterpretations. To investigate source various terrigenous fractions southeastern Africa, region redistribution, we have performed...
Abstract. In tropical eastern Africa, vegetation distribution is largely controlled by regional hydrology, which has varied over the past 20 000 years. Therefore, accurate reconstructions of and hydrological changes are crucial for a better understanding climate variability in southeastern African region. We present high-resolution pollen records from marine sediment core recovered offshore Rufiji River delta. Our data document significant shifts assemblages during last deglaciation,...
The Mercator mud volcano, located in the Gulf of Cadiz off coasts Spain, Portugal, and Morocco (Figure 1), may provide an accessible field laboratory for studying local active venting its possible internal external controls. recent discovery first deep ocean ‘brown smoker’ chimney this area can possibly be linked with disintegration a gas hydrate layer between seafloor subsurface level that is dependent on pressure temperature. For more than decade, international marine scientific community...
The southwest of Morocco is considered to be an area refuge within the Mediterranean region, hosting endemic tropical Argan tree. This region presently subject severe droughts, desertification and land degradation, likely facing increased climate variability socio-economic stress in future. Here, we use stable hydrogen carbon isotope composition (δD δ 13 C) plant-waxes a high-resolution marine sediment core (GeoB8601-3) collected off Cape Ghir southwestern Morocco, combination with published...
