    briefing paper page 1 Djibouti: Changing Influence in the Horn’s Strategic Hub David Styan Africa Programme | April 2013 | AFP BP 2013/01 Summary points zz Change in Djibouti’s economic and strategic options has been driven by four factors: the Ethiopian–Eritrean war of 1998–2000, the impact of Ethiopia’s economic transformation and growth upon trade; shifts in US strategy since 9/11, and the upsurge in piracy along the Gulf of Aden and Somali coasts. zz With the expansion of the US AFRICOM base, the reconfiguration of France’s military presence and the establishment of Japanese and other military facilities, Djibouti has become an international maritime and military laboratory where new forms of cooperation are being developed. zz Djibouti has accelerated plans for regional economic integration. Building on close ties with Ethiopia, existing port upgrades and electricity grid integration will be enhanced by the development of the northern port of Tadjourah. zz These strategic and economic shifts have yet to be matched by internal political reforms, and growth needs to be linked to strategies for job creation and a renewal of domestic political legitimacy. www.chathamhouse.org Djibouti: Changing Influence in the Horn’s Strategic Hub page 2 Djibouti 0 25 50 km 0 10 20 30 mi Red Sea National capital District capital Ras Doumeira Town, village B Airport, airstrip a b Wadis ERITREA a l- M International boundary a n d District boundary a b Main road Railway Moussa Ali ETHIOPIA OBOCK N11 N11 To Elidar Balho Obock N14 TADJOURA N11 N14 Gulf of Aden Tadjoura N9 Galafi Lac Assal Golfe de Tadjoura N1 N9 N9 Doraleh DJIBOUTI N1 Ghoubbet Arta N9 El Kharab DJIBOUTI N9 N1 DIKHIL N5 N1 N1 ALI SABIEH N5 N5 Abhe Bad N1 (Lac Abhe) Ali Sabieh DJIBOUTI Dikhil N5 To Dire Dawa SOMALIA/ ETHIOPIA SOMALILAND Source: United Nations Department of Field Support, Cartographic Section, Djibouti Map No.

  • Environmental Management of Assal-Fiale Geothermal Project in Djibouti: a Comparison with Geothermal Fields in Iceland
    Orkustofnun, Grensasvegur 9, Reports 2015 IS-108 Reykjavik, Iceland Number 7 ENVIRONMENTAL MANAGEMENT OF ASSAL-FIALE GEOTHERMAL PROJECT IN DJIBOUTI: A COMPARISON WITH GEOTHERMAL FIELDS IN ICELAND Ali Barreh Adaweh Ministry of Energy in charge of Natural Resources Cite Ministerielle, Djibouti REPUBLIC OF DJIBOUTI [email protected] ABSTRACT The geological characteristics of the Assal rift are favourable for the development of geothermal energy in Djibouti. The Government plans to exploit the geothermal resources in the Assal region to enable public access to a reliable, renewable and affordable source of energy. The Assal-Fiale geothermal project is located on a site that has scientific, ecological and tourist importance. Using the geothermal resource is believed to be a positive way to generate electricity in the area but improper management of the resource can cause possible negative impacts on the environment. Environmental impacts assessment will help to understand and minimize negative impacts of the project and with good management can support the environmental, economic and social goals of sustainability. This report presents the possible environmental impacts of the project and their management which aims to minimize them in accordance with national and international regulations and the geothermal utilization experience gained in Iceland. 1. INTRODUCTION 1.1 Purpose of this study The geothermal potential in Djibouti is estimated around 1000 MWe, distributed among thirteen sites and mainly located in the Lake Assal region. The government’s plans, with its first geothermal project, are to exploit the geothermal resources in the Lake Assal region to enable public access to a reliable, renewable and affordable source of energy.

  • China and the EU in the Horn of Africa: Competition and Cooperation?
    APRIL 2018 China and the EU in the CRU Policy Brief Horn of Africa: competition and cooperation? The Horn of Africa is one of the most geo-strategically important regions of the world, and one of the main theatres in which the Sino-African four-pronged approach – based on economic, ideological, political and security interests – unfolds. This policy brief unpacks the dynamics of Chinese engagement with the Horn of Africa, with Ethiopia as a case study. The brief maintains the view that although European Union (EU) and Chinese activities in the Horn of Africa often differ in ideological and political interests, there is significant complementarity in economic and security interests. It also suggests that by making a balanced assessment of China’s activities in the region, and by understanding where the two agendas diverge and where they are complementary, the EU could work with China to strengthen stability in the region. The brief will conclude with recommendations for EU policy makers and private sector actors who seek further engagement with the Horn.

ABSTRACT Lake Assal is located in the east of the Afar depression, at an altitude of 155 meters below sea level, making it the lowest point on the African Continent. It is separated from Ghoubhet-el- Kharab, which is the extension of the Gulf of Aden via the Gulf of Tadjourah, by the Ardoukoba volcano, which last erupted from November 1978. Fourteen samples were analysed by XRD, to identify clay minerals, and XRF to identify to chemical constituents. Bulk samples analysis showed plagioclase, forsterite, fayalite, chl/Sme, Illt/sme and hematite. In Addition, thin Section observation of two samples from Assal and one sample Otake-Hatchobaru. The Otake- Hatchobaru geothermal field is located in the northwest of Kuyju volcano, Japan.

  • Restore the Salton Sea
    Restore the Salton Sea . addressing the challenges The Oceanwater Corridor new oceanwater technologies, new solutions, and new opportunities . Photo coutesy of EcoMedia Compass Fall 2016 Introduction The world is in the midst of a fresh water crisis. It is time to seriously address those issues. The Salton Sea is a preeminent example with doable solutions. And The Seawater Works team has answers, experience and focus to stop the level of the Salton Sea from further recession because of evaporation and declining agricultural drainage and Colorado River water delivery and to raise the future level of the Sea to design proportions. We have a history of using unlimited oceanwater from the Gulf of California in Sonora for agriculture, aquaculture and wetlands and in Eritrea, East Africa in controlling extreme salinity differences by horizontal separation while providing jobs, products and habitats. The State of California and many agencies have spent years studying solutions to resolve the problems of the lowering of the Sea, causing exposed playa health dangers and the resulting salinity that has killed fish populations and left the bird communities with nothing on which to feed. Freshwater from the oversubscribed Colorado River is needed to provide water for major cities including San Diego, Los Angeles, Phoenix, Las Vegas, Tijuana and Mexicali. And much of the country’s produce and cattle depend on fresh water irrigated agriculture. Seawater Works defines the solution as designing and implementing the Oceanwater Corridor™, beginning in the Gulf of California, enriching the Mexicali Valley, crossing the Mexican/US border, enhancing the Imperial Valley and restoring the Salton Sea and its environs and communities can do just that.

The NCC Geography Bee How it works? Welcome Aboard! The Geography Bee has been an NCC tradition for many years. Originally brought to NCC by parents, the NCC staff have continued this tradition to help our students enjoy geography as much as we do! These Geo Bee packets are updated periodically by volunteers and every effort is made to ensure accuracy. This year the Geography Bee packet will take students on an exploration of much of Africa and Asia. (We studied North Africa last year.) On these two continents, you will explore fascinating countries, tropical islands, the highest mountains on Earth, the home of ancient civilizations, wild rivers, dense jungles and the more. ● Students in grades 3-6 should try to complete the Geo Bee packet. ● Completed packets may be turned into a basket on the circulation desk in the Media Center. ● Students may receive a small prize or bookmark for completing the packet. ● After a few weeks of study in class and in Media, students will take a short quiz based on facts from the packet ● The top five scorers in each homeroom will become that homeroom’s Geography Bee team ● Teams are invited to a friendly competition on Geography Bee Day.
