Research priorities for climate mobility
The escalating impacts of climate change on the movement and immobility of people, coupled with false but influential narratives of mobility, highlight an urgent need for nuanced and synthetic research around climate mobility. Synthesis of evidence and gaps across the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report highlight a need to clarify the understanding of what conditions make human mobility an effective adaptation option and its nuanced outcomes, including simultaneous losses, damages, and benefits. Priorities include integration of adaptation and development planning; involuntary immobility and vulnerability; gender; data for cities; risk from responses and maladaptation; public understanding of climate risk; transboundary, compound, and cascading risks; nature-based approaches; and planned retreat, relocation, and heritage. Cutting across these priorities, research modalities need to better position climate mobility as type of mobility, as process, and as praxis. Policies and practices need to reflect the diverse needs, priorities, and experiences of climate mobility, emphasizing capability, choice, and freedom of movement
Mineralogical and physicochemical characterization of the Jbel Rhassoul clay deposit (Moulouya Plain, Morocco)
This study aims at the mineralogical and physicochemical characterization of clays of
the Missour region (Boulemane Province, Morocco). For this, three samples were
collected in the Ghassoul deposit. The analyses were carried by X-ray diffraction
(XRD), X-ray fluorescence (XRF) and Scanning Electron Microscopy (SEM). The
thermal analysis from 500 to1100°C was also performed on studied samples, and the
fired samples were characterized by XRD and SEM. The XRD results revealed that raw
Ghassoul clay consists mainly of Mg-rich trioctahedral smectite, stevensite-type clay,
which represents from 89% to 95% of the clay fraction, with a small amount of illite
and kaolinite. The associated minerals are variable amount of quartz, dolomite,
hematite, gypsum and K-feldspars. The chemical analysis confirms the presence of Mgrich
smectite (stevensite) with largest amount in sample containing the highest MgO.
The SEM micrographs revealed the presence of automorphous structures with petalslike
shape typical of smectite. The Thermal transformations determined by X-ray
diffraction indicated that stevensite was transformed to enstatite from 800ºC. Diopside
starts to appear from 700°C, which is confirmed by SEM observations, and the quartz is
transformed to cristobalite when the temperature exceeds 1100°C
