“…Sustainable materials utilized in eco-friendly construction include steel slag, fly ash, reclaimed concrete and asphalts, high-and low-density waste plastics, waste rubber tires, asphalt shingles, mine tailings, various agricultural wastes, and aquaculture wastes such as seashells, to list a few [21][22][23][24]. To facilitate the practice of eco-friendly construction and maintenance generally, and in green building construction, in particular, the need for stakeholder extensive participation and interaction especially with key decision-makers at organization level was identified as a paramount factor [25][26][27]. Hence the optimal blend of locally-sourced and non-locally-sourced recycled aggregates is recommended to support conservation [28,29].…”

This research appraised the effects of recycling senilia senilis waste seashells as a full or partial substitution for natural coarse aggregate (granite) in eco-friendly concrete production. The design mix employed a 1:2:4 concrete mix ratio for M25 grade, a w/c ratio of 0.5, river sand as fine aggregate, ordinary Portland cement (OPC) as a binder, and varying proportions of crushed seashells and granite as coarse aggregates (0:100, 10:90, 20:80, 30:70, 40:60, and 50:50). Laboratory tests revealed that workability requirements were only met with a 10%-40% seashell addition, workability decreased with increasing seashell percentages. The compressive strength increased with curing age but decreased with the additions of seashells. The seashell-modified mixes failed to reach the design target strength for M25 concrete. Nonetheless, the 10 and 20% seashell-modified mixes achieved the required strength for M20 concrete. Split tensile strength increased with curing age for all mixes, the seashell-modified mixes yielded slightly reduced tensile strength values compared to the unmodified mix at all curing stages. However, the 10%, 30%, and 40% seashell-modified batches attained recommended split tensile strength values on the 28th day. Furthermore, high correlations were observed between the datasets of the some of the measured parameters, and variations for Split tensile strength as a function of seashell percentage and compressive strength were developed discretely by fitting the experimental data to the numerical models. Relationships were also developed for compressive strength and workability as functions of seashell percentage. Eco-friendly building construction recycling waste seashells is encouraged as it offers positive economic and environmental prospects.

“…Second, this paper adds to the stakeholder literature (Freeman et al, 2010;Knaggård et al, 2019;Lyon et al, 2020) by establishing that CEO social capital relates to CSP but through stakeholder integration capability. Given that stakeholders have implications for a firm's strategy (Freeman et al, 2010;Plaza-Úbeda et al, 2010), this paper sought to integrate stakeholder integration capability as a mediator of the CEO capital-CSP relationship.…”

This paper investigates the role of a chief executive officer's (CEO's) social capital on corporate social performance (CSP) through the mediating mechanism of stakeholder integration. Data were collected from 256 small and medium‐sized enterprises (SMEs). Results from the hierarchical regression analysis suggest that stakeholder integration mediates the relationship between CEO social capital and CSP. The results further reveal that the effect of CEO social capital on stakeholder integration is moderated by CEO tenure, such that the relationship is more significant for long‐tenured CEOs than short‐tenured CEOs. These findings extend the social capital and corporate social responsibility research and practice.

“…L'amélioration des rendements de céréales demeure limitée (une moyenne de 1,64 tonnes par ha durant la période du PMV, alors qu'elle était de 1,17 tonnes par ha entre 2001 et 2007, selon ONICL, 2020), inférieure à la moyenne africaine (2,34 tonnes par ha). Malgré les efforts pour généraliser les usages des engrais dans un pays leader en termes de production et de transformation des phosphates (Lyon et al, 2020), les niveaux limités de productivité des Fig. 3.…”

Le secteur agricole constitue une activité importante au Maroc, représentant 14 % du produit national brut et employant 40 % de la population active. Avec l’émergence de la pandémie de la Covid-19, il a été ébranlé par des incertitudes économiques et par la distanciation physique qui a accentué les contraintes du travail. Toutefois, l’agriculture s’est imposée comme une activité cruciale, puisqu’elle a continué à assurer l’approvisionnement alimentaire à des prix abordables. La pandémie, qui s’est déclarée en une année très sèche, a offert une opportunité pour réviser les principales contraintes auxquelles fait face le secteur agricole : manque d’eau et faible rémunération du travail. Elle a aussi attiré l’attention de l’opinion publique sur les quantités importantes de denrées vivrières importées. La balance des paiements des produits alimentaires demeure négative, malgré des exportations de produits agricoles mises en relief par le discours officiel. En outre, des études récentes ont montré que ces dernières dépendent avant tout d’usages accrus et souvent déraisonnables d’eau souterraine, malgré les subventions à la conversion des systèmes d’irrigation gravitaire vers le goutte-à-goutte. Des suivis d’exploitations ont démontré que ces subventions ont généré une expansion de la surface irriguée avec des cultures à besoins hydriques élevés. Cette situation doit être considérée comme l’opposé de l’objectif recherché : une amélioration de la valorisation de l’eau. Il faut donc reconnaître que l’agriculture de l’ère post Covid-19 devra être différente. Un changement de paradigme doit s’opérer où la valorisation de l’eau pluviale figurera dans les priorités, de concert avec la souveraineté alimentaire. Il doit englober différentes dimensions, comme la préservation de l’environnement, le développement du monde rural et de systèmes alimentaires durables, mais aussi garantir l’inclusion sociale et de meilleures rémunérations du travail agricole, afin d’assurer son attractivité et réduire l’exode rural.
