Hydropower is the Introduction main source of clean energy in most mountainous areas of Africa. The consistent flow of water from mountains is Mountains cover 25% of the world’s land surface, and are essential for this clean energy. In a continent highly home to about 10% of its population, most of whom depend dependent on traditional energy sources and badly affected on mountain resources for their livelihoods. A key link by rising oil prices, mountains can thus significantly between the actions of mountain and wider populations is contribute to energy security. The conditions in mountain that most of the world’s major rivers rise in mountain areas: regions allow for higher and better quality yields, significantly mountains are the world’s ‘water towers’, and the contributing to regional and lowland food security. sustainable management of their watersheds is vital for the Mountains house many ecosystems such as forests, provision of high-quality water to billions of people, as well as grasslands, drylands, rivers and wetlands.

The Reintroduction of Eurasian Griffon Monachus Vultures to France
Chancellor, R. D. & B.-U. Meyburg eds. 2004 Raptors Worldwide WWGBP/MME A Success Story: The Reintroduction of Eurasian Griffon Gyps fulvus and Black Aegypius monachus Vultures to France Michel Terrasse, François Sarrazin, Jean-Pierre Choisy, Céline Clémente, Sylvain Henriquet, Philippe Lécuyer, Jean Louis Pinna, and Christian Tessier ABSTRACT By the end of the 1960s, the future of vultures in France appeared bleak. Apart from the western half of the Pyrenees, with residual populations of Eurasian Griffon Gyps fulvus and Bearded Vultures Gypaetus barbatus, and Corsica with a few Bearded Vultures, most of France had lost its large vultures including the Black Vulture Aegypius monachus. Within the scope of a national conservation campaign, a process to restore raptor communities began. Concerning vultures, this was completed through reintroduction programmes. After the success of the Griffon Vulture reintroduction, started in 1968 in the Grands Causses of the Massif Central, other programmes followed in the 90s: Black Vultures in the Massif Central and then Griffon Vultures in the Southern Alps. In 2003 a viable population of Griffon Vultures in the Massif Central contained around 110 pairs. The same situation occurred in the Alps with about 50 breeding pairs of Griffon Vultures. Ten years after the beginning of the Black Vulture releases, the free ranging population included 11 breeding pairs. Accurate monitoring during the reintroduction period allowed us to estimate demographic parameters such as survival and breeding rates, evolution of breeding and foraging territories, main threats, movements between reintroduced populations and those from neighbouring countries, acceptance by people and the beneficial part played by vultures in what is called sustainable development. -
Interpretation of the Regional Significance of the Chain Lakes Massif, Maine Based Upon Preliminary Isotopic Studies
Maine Geological Survey Studies in Maine Geology: Volume 4 1989 Interpretation of the Regional Significance of the Chain Lakes Massif, Maine based upon Preliminary Isotopic Studies Michael M. Cheatham* William J. Olszewski Henri E. Gaudette Institute for the Study of Earth, Oceans and Space Science and Engineering Research Building University of New Hampshire Durham, New Hampshire 03824 *Present address: Department ofGeological Sciences Snee Hall Cornell University Ithaca, New York 14853 ABSTRACT The Chain Lakes massif of northwestern Maine and adjacent Quebec contrasts sharply in lithology, metamor phism, deformation, and age with surrounding rocks, and has been considered a suspect terrane in the northern Appalachians. The massif is composed of aquagene metavolcanic and metasedimentary rocks, massive granofels and poorly stratified gneisses containing clasts of volcanic, plutonic, and sedimentary rocks which show evidence of previous deformation and metamorphism. Rocks of the Chain Lakes massif have been metamorphosed to upper amphibolite-granulite fades, although a later retrograde event (epidote-pumpellyite fades) is also recognized. Mild thermal effects and cataclasis resulted from overthrusting of the Boil Mountain ophiolite in the southern portion of the massif. The massif has generally been assigned a Precambrian age. Although previous age work on the massif is ambiguous, stratigraphic constraints and isotopic results from surrounding rocks constrain the age of the massif only to the pre-Late Ordovician. A total of 40 whole rock samples have been petrographically examined, 27 of which were analyzed by Rb-Sr and Sm-Nd isotopic techniques in order to determine the number, grades, and ages of the various metamorphic events affecting the massif, the age of the protolith material, and to constrain the age of deposition of the material in the massif. -

WATER RESOURCES ASSESSMENT of HAITI August 1999
WATER RESOURCES ASSESSMENT OF HAITI August 1999 Haiti Dominican Republic US Army Corps of Engineers Mobile District and Topographic Engineering Center Water Resources Assessment of Haiti Executive Summary Haiti is one of the most densely populated countries in the world and one of the poorest in the Western Hemisphere. The population has already outstripped domestic food production, and it is estimated that the population will be 8 million by the year 2000. One-third of the population lives in the Département de l’Ouest where Port-au-Prince is located. Heavy migration from rural areas to towns and cities occurring over the past decade has adversely affected the distribution of the water supply. Access to water and sanitation facilities is inadequate, contributing to poor living conditions, disease, and a high mortality rate. In 1990 only 39 percent of the 5.9 million residents had adequate access to water and only 24 percent to sanitation. The lack of potable water for basic human needs is one of the most critical problems in the country. Given the rainfall and abundant water resources, there is adequate water to meet the water demands, but proper management to develop and maintain the water supply requirements is lacking. However, the water supply sector is undergoing complete transformation. Although currently there is no comprehensive water policy, progress is being made towards establishing a national water resources management policy. Numerous agencies and non-government organizations (NGO’s) are working to provide water, many of which conduct their missions with little or no coordination with other agencies, which creates duplication of work and inefficient use of resources. -

Fundamental to all aspects of human existence, culture shapes the way humans view life and functions as a tool we use to adapt to our social and physical environments. A culture is the sum of all of the beliefs, values, behaviors, and symbols that have meaning for a society. All human beings have culture, and individuals within a culture share a general set of beliefs and values. -
10 Best Mountain Treks in Africa 1 MOUNT KILIMANJARO TANZANIA
10 Best Mountain Treks in Africa From the Atlas Mountains of Morocco all the way down to South Africa’s Drakensberg, Africa has got the best and most popular trekking destinations with Mount Kilimanjaro, the highest mountain in the continent at the top of the list. 1 MOUNT KILIMANJARO TANZANIA Climbing Africa’s highest mountain peak is not for the faint of heart. At 19,336 feet high, Mount Kilimanjaro is Africa’s highest peak. Every year at least 20,000 people attempt to climb up the mountain through the 5 different climatic zones. Situated in the Kilimanjaro National Park in Tanzania, this geological wonder is any mountaineers dream climb. There are different routes up Mount Kilimanjaro. Each route has a degree of difficulty in climbing, traffic and scenic beauty. The longer the route you take the less difficult the climbing is and the more you enjoy trekking up the mountain. The least difficult routes are Marangu and Rongai; the more difficult routes are Machame, Shira, and Lemosho. The longer routes have more difficult hiking but you'll be more acclimatized and your chances of reaching the summit are therefore higher. Kilimanjaro National Park is rich in unique bird life, wildlife and beautiful flora. We suggest getting to know the area before your trek, as there is so much to enjoy before your climb. Due to the proximity to the equator and warm Indian ocean, much of the mountain slopes are rich areas of forest, with 195 unique bird species that call this home. As you ascend the mountainous terrain, the landscape changes from lush forest to alpine moorland, interspersed with valleys and ravines. -
