    The present study was carried out to assess the quality and the suitability of the well waters for drinking in M’bahiakro city (centre-east of CĂŽte d’Ivoire). The work was performed on 71 wells in February 2012 (dry season) and June 2012 (rainy season). Groundwater levels and physico-chemical parameters (pH, temperature, electrical conductivity, redox potential (Eh), Total Dissolved Solid (TDS) and Salinity) were measured to assess the water table fluctuation and the groundwater quality. Standardized Principal Component Analysis (SPCA) was calculated to group the well waters and to evaluate their suitability for drinking according to different classes. Water table varies between 125 and 135 m during the dry season and between 127 and 136 m during the rainy season with a West-Est flow direction. The recharge values ranged between 0.57 m and 5.57 m. Wells waters are generally acidic (pH<6.5), high mineralized with conductivities and Total Dissolved Solids (TDS) respectively above 600 ”S/cm and 300 mg/l. Well water salinity values ranged between 0.30 and 0.5%. The Standardized Principal Component Analysis (SPCA) allowed distinguishing three important groups of water within M’bahiakro area: the first group of wells with high mineralized water, the second group of wells with high potential redox (Eh) and the third group of wells with pH closer to neutral. The first and second groups are not very suitable for drinking because they are suspected of being contaminated by anthropogenic sources such as septic tanks and wild dump. Waters of these wells need to be treated before any domestic use

    Re-imagining African-Nordic relations in a changing global order

    Ahead of the 20th Annual African–Nordic Foreign Ministers’ meeting, scheduled for 14 June 2022 in Helsinki, this study considers how turbulence in the international system may affect relations between Africa and the Nordic region (Denmark, Finland, Iceland, Norway and Sweden). In particular, it examines how the special relationship between these two regions may be affected by changes in the global order, and how it may have to adapt to ensure that the relationship evolves and remains relevant for both regions. The report evaluates the levels and spheres of African–Nordic cooperation and is divided into four parts. First, an overview of African and Nordic positions and priorities is presented. Second, Africa’s strategic partnerships with various countries and regions – China, Europe, India, Russia and Turkey – are explored, in order to compare the Africa–Nordic relationship with these others. Contributors examines how these partnerships are structured, the types of initiatives or activities undertaken to sustain them, and how these partnerships have adapted to today’s global order. Third, the report analyses several elements of the Africa–Nordic relationship that may shape the direction of the partnership in future, including: - Nordic development assistance to Africa; - Migration and its potential implications for Africa and the Nordic countries, including the impact of the war in Ukraine; - Africa–Nordic trade, investment and loans; - Political, peace and security relations and cooperation; - African and Nordic support for, and cooperation in, multilateral organisations; - Climate change. Finally, the various sections of the report are synthesised, and overall findings are presented

    This book presents the abstracts of the selected contributions to the First International Colloquium on Mines and Society (CIMS) organized by The Higher Institute of Mining and Geology of Boke. The theme of this colloquium was "Mining and Sustainable Development, a major challenge for an Emerging Africa" which aims to bring together teachers, researchers, and Professionals from different backgrounds in order to exchange the results of their research work, share their points of view on the issue of mining and sustainable development. It also aims to define, in a collaborative and inclusive manner, research prospects or future projects between all the actors involved in this field.
