This video clip brings snippets from Mara-Mediterra’s Fourth progress meeting and of the field trip which took place on, respectively, 29 and 30 April and 1 May 2024. Both events were co-hosted by AMENHYD, the Algeria partner in the consortium and ANVREDET, the national agency for the valorisation of research and technological development results. In his welcome address, Dr. Boualem Tatah, advisor to the Minister for Research in Algeria, spoke on the importance of cross-border knowledge exchange to address the pressing challenges associated with a changing climate. Dr. Mustapha Adjadj reiterated on how the latter had significantly slowed down the country’s flagship project of greening the desert, known as the Green Dam project. The field trip took the partnership to Djelfa, known as the Gateway to the Sahara. We visited the site where the Green Dam project had been launched back in the 1970s and where AMENHYD is now validating a novel micro-ecosystem-based afforestation protocol. The field trip started off with a visit to the stunning botanical garden of Hamma in the country’s capital Algiers. It is known as the test garden, since already since its inception in 1832, the garden served as an experimental site for the growing of plant and tree species that were brought in from all around the world. Over time, the garden continued to expand from an initial 5 hectares to 38 hectares of gardens and 20 hectares of arboretum which are overseen by the Algerian National Institute of Agronomical Research. Look out for the footage in the clip of the Mara-Mediterra Partnership under the tree that featured in the 1932 movie of Tarzan, the Ape Man.
