Cultural Landscape Planning: the Mexicali Valley, Mexico
The Sustainable City VII, Vol. 1 457 Cultural landscape planning: the Mexicali Valley, Mexico R. I. Rojas-Caldelas1, C. A. Pena-Salmon1 & J. Ley-Garcia2 1Faculty of Architecture and Design, Autonomous University of Baja California, Mexicali, México 2Institute of Research in Social Sciences, Autonomous University of Baja California, Mexicali, México Abstract Initiating around the eighties, the academic training of landscape architects in Mexico is quite recent compared with the tradition in Europe and the U.S. Also new, is the development of landscape research conducted mainly by geographers, urban planners and other professionals trained in natural sciences, whose work is primarily oriented to land use management for urban development and conservation of natural resources or cultural heritage purposes. However, the issue of the cultural landscape in Mexico has been little explored and lacks any integrated and multidisciplinary methodology to bring together social, cultural and natural processes for study. Therefore, this work focuses on the presentation of an appropriate methodology to address the issue of the evolving cultural landscape of the Valley of Mexicali. This work has been developed into three stages: characterization, multiple assessment of landscape and integration of strategies for their management. Thus progress will be presented for the characterization of physical units, landscape components through pictures, visual and spatial patterns of landscape that structure the region and its settlements. As a partial result it was found that multi-valued zones visually and spatially exist in the Mexicali Valley, as well as activities that give character and differentiate it from other agricultural areas of Baja California. Keywords: cultural landscape, landscape assessment methodologies, visual and spatial assessment, sustainable landscape planning. -

Djibouti: Z Z Z Z Summary Points Z Z Z Z Renewal Ofdomesticpoliticallegitimacy
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. -

Selenium Roy A
Nutrient Dynamics in the Salton Basin- Implications from Calcium, Uranium, Molybdenum, and Selenium Roy A. Schroeder, U. S. Geological Survey, San Diego, California and Willian H. Orem, U.S. Geological Survey, Reston, Virginia H31B-02 ABSTRACT: The Salton Sea has been accumulating chemical constituents delivered by its tributary streams for nearly 100 years because it has no outlet. The buildup of chemicals that are highly soluble and unreactive, such as chloride, has resulted in the development of a quasi- marine lake. In contrast, chemicals that react to form insoluble phases ultimately enter the sediment that accumulates on the floor of the Sea. Solubility properties are especially relevant for two important contaminants, selenium and nitrogen. The selenium is contained in Colorado River water used for irrigation, and nitrogen is derived mostly from chemical fertilizer in agricultural runoff. Both are delivered to the Salton Sea as highly soluble oxyanions by the Alamo and New Rivers, which are relatively high in dissolved oxygen at their outlets to the Salton Sea, but are removed as reduced species in anoxic sediment on the Sea’s floor. Without this removal mechanism, selenium concentration would presently be about 400 micrograms per liter and nitrogen would be about 100 milligrams per liter in the Salton Sea’s water, rather than the observed concentrations of only about 1 microgram per liter and 5 milligrams per liter, respectively. Ironically, anoxic conditions responsible for producing the noxious odors and low oxygen conditions that lead to periodic dieoffs of large numbers of fish in the Salton Sea have prevented aqueous selenium and nitrogen from reaching levels that could indeed pose an extreme environmental hazard. -
Biological Goals and Objectives
Appendix C Biological Goals and Objectives Draft DRECP and EIR/EIS APPENDIX C. BIOLOGICAL GOALS AND OBJECTIVES C BIOLOGICAL GOALS AND OBJECTIVES C.1 Process for Developing the Biological Goals and Objectives This section outlines the process for drafting the Biological Goals and Objectives (BGOs) and describes how they inform the conservation strategy for the Desert Renewable Energy Conservation Plan (DRECP or Plan). The conceptual model shown in Exhibit C-1 illustrates the structure of the BGOs used during the planning process. This conceptual model articulates how Plan-wide BGOs and other information (e.g., stressors) contribute to the development of Conservation and Management Actions (CMAs) associated with Covered Activities, which are monitored for effectiveness and adapted as necessary to meet the DRECP Step-Down Biological Objectives. Terms used in Exhibit C-1 are defined in Section C.1.1. Exhibit C-1 Conceptual Model for BGOs Development Appendix C C-1 August 2014 Draft DRECP and EIR/EIS APPENDIX C. BIOLOGICAL GOALS AND OBJECTIVES The BGOs follow the three-tiered approach based on the concepts of scale: landscape, natural community, and species. The following broad biological goals established in the DRECP Planning Agreement guided the development of the BGOs: Provide for the long-term conservation and management of Covered Species within the Plan Area. Preserve, restore, and enhance natural communities and ecosystems that support Covered Species within the Plan Area. The following provides the approach to developing the BGOs. Section C.2 provides the landscape, natural community, and Covered Species BGOs. Specific mapping information used to develop the BGOs is provided in Section C.3. -

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. -
