The purpose of this paper is to seek to establish an effective governance framework for waqf (Islamic endowment) in the Republic of Guinea that would assist in enhancing socio-economic activities and eradicating poverty in the country.

It examines key governing features within the said country’s waqf legal framework and undertakes a comparison with other countries’ legal frameworks. This paper also examines waqf-related legal references of Guinea and other countries and analyses relevant online sources such as journal articles, research papers, webpages as well as informal discussions with persons informed on the subject matter within and outside the Republic of Guinea.

This paper identifies a number of prevailing issues affecting the development of the institution of waqf in the Republic of Guinea and, thereafter, proposes key reformatory measures. These include the passing of general codified legislation that comprehensively governs waqf affairs in the country and the setting up of a dedicated supervisory entity and competent managerial bodies to ensure the smooth and effective operation of the institution in the country.

This research proposes an innovative and befitting governance framework for waqf operations in the Republic of Guinea. These recommendations, if correctly adopted, would ensure the viability and efficacy of the institution of waqf in the Republic of Guinea and would lead to socio-economic development, as has been the case in other nations. Moreover, other countries with underdeveloped waqf governance systems could also model their waqf operations based on these recommendations, as they are most likely already encountering or going to encounter identical issues in this particular field.

The purpose of this paper is to review cases of artificial reefs built through additive manufacturing (AM) technologies and analyse their ecological goals, fabrication process, materials, structural design features and implementation location to determine predominant parameters, environmental impacts, advantages, and limitations.

The review analysed 16 cases of artificial reefs from both temperate and tropical regions. These were categorised based on the AM process used, the mortar material used (crucial for biological applications), the structural design features and the location of implementation. These parameters are assessed to determine how effectively the designs meet the stipulated ecological goals, how AM technologies demonstrate their potential in comparison to conventional methods and the preference locations of these implementations.

The overview revealed that the dominant artificial reef implementation occurs in the Mediterranean and Atlantic Seas, both accounting for 24%. The remaining cases were in the Australian Sea (20%), the South Asia Sea (12%), the Persian Gulf and the Pacific Ocean, both with 8%, and the Indian Sea with 4% of all the cases studied. It was concluded that fused filament fabrication, binder jetting and material extrusion represent the main AM processes used to build artificial reefs. Cementitious materials, ceramics, polymers and geopolymer formulations were used, incorporating aggregates from mineral residues, biological wastes and pozzolan materials, to reduce environmental impacts, promote the circular economy and be more beneficial for marine ecosystems. The evaluation ranking assessed how well their design and materials align with their ecological goals, demonstrating that five cases were ranked with high effectiveness, ten projects with moderate effectiveness and one case with low effectiveness.

AM represents an innovative method for marine restoration and management. It offers a rapid prototyping technique for design validation and enables the creation of highly complex shapes for habitat diversification while incorporating a diverse range of materials to benefit environmental and marine species’ habitats.
