| This paper presents the evolution of aquaculture in North Africa during the 20 last years, and the assets and bottlenecks for each country. This work uses the results of the European project Aquamed (2011-2013). The analysis of the evolutions of this sector, including research and development allows to establish a diagnosis on the strengths and the weaknesses in the four countries (Morocco, Algeria, Tunisia and Egypt). The retrospective analysis helps in identifying solutions for a more sustainable development. It also contributes to select priorities for action in a long-term vision (2035). This double overview, on the past and the future, should help decision-makers and experts to identify the best politics for a sector, which has a high potential in the... |

| The West Palaearctic species of the genus Bassus Fabricius, 1804 (Braconidae: Agathidinae) are revised and keyed, together with the similar Agathis mediator group. Twenty-two species of Bassus and four species of the Agathis mediator group are recognized, of which three are new: B. barbieri from Algeria, B. epinotiae from Great Britain, and B. graecus from Greece. Seven species are synonymized: Microdus lugubrator Ratzeburg, 1852 with B. mediator (Nees, 1814), Microdus punctatus Abdinbekova, 1975 with B. rugulosus (Nees, 1834), Microdus annae Enderlein, 1908, Microdus victoris Telenga, 1955, and M. anuphrievi Tobias, 1986 with B. tumidulus (Nees, 1814), Microdus rufiventris Abdinbekova, 1975 with B. nugax (Reinhard, 1867), and Agathis minuta Niezabitowski,... |

| Disophrys ovalis Fahringer, 1937 (Hymenoptera: Braconidae: Agathidinae) from Egypt is redescribed and transferred to the genus Troticus Brullé, 1846 (comb. nov.) with Disophrys aegyptiaca Fahringer, 1937, as its junior synonym (syn. nov.). For the first time a reliable host record for the genus and for T. ovalis is given. The holotype of Troticus melamopterus Cameron, 1903 has been examined by the first author and is transferred to the genus Cremnops Foerster, 1862 (C. melamopterus Cameron, 1903 comb. nov.). |

| The West Palaearctic species of the genus Agathis Latreille, 1804 (Braconidae: Agathidinae) are revised and keyed. Forty-six species of Agathis are treated as valid, of which 29 occur in Europe; three species of the former Agathis mediator group (Bassus brevicaudus (Reinhard, 1867) comb. nov., B. mediator (Nees, 1814), and B. pumilus (Ratzeburg, 1844)) are transferred to the genus Bassus Nees, 1804. One new species (A. hemirufa) from Spain is described. The following species are synonymised: Agathis longicauda Kokujev, 1895, A. albanica Fischer, 1957, A. syriaca Fischer, 1957, A. caucasica Tobias, 1963, and A. taiwanensis Chou & Sharkey, 1989, with A. anglica Marshall, 1885; A. propinqua Kokujev, 1895, A. jakowlewi Kokujev, 1895, and A. anchisiades... |

| This survey first presents an inventory of fish species in the three studied sites. Altogether 17 fish species were found in Merja Zerga (Morocco), 25 species in Garâat Ichkeul and 16 species in Edku lagoon. Three fish groups live in these brackish lakes : sedentary fish, marine fish and freshwater fish. The second part of the study deals with the production of the different species. This production mainly rests upon Mugilidae and Anguilla in Merja Zerga and Ichkeul, while, in Edku, Tilapia is its principal component. In all these sites fish production seems to be decreasing these last years, because of over-fishing and essentially of the deterioration of the environmental factors, especially the hydrologic ones. |

| Although several institutional and management approaches that address the degradation of the rangelands have been tested in the dry areas of Central and West Asia and North Africa (CWANA), impact has been limited. Nonetheless, the development of National Action Plans to combat desertification highlights the interest of governments to tackle this issue. Payment for Environmental Services (PES) may be a viable policy option, though, to date, most PES programs have focused on the management of different resources (forests, watersheds). The purpose of this paper is to examine whether PES could be a viable option to promote sustainable rangelands management in the dry rangelands of CWANA. Specifically, it focuses on the scientific gaps and knowledge related to... |
