Alcolapia Grahami ERSS
Lake Magadi Tilapia (Alcolapia grahami) Ecological Risk Screening Summary U.S. Fish & Wildlife Service, March 2015 Revised, August 2017, October 2017 Web Version, 8/21/2018 1 Native Range and Status in the United States Native Range From Bayona and Akinyi (2006): “The natural range of this species is restricted to a single location: Lake Magadi [Kenya].” Status in the United States No records of Alcolapia grahami in the wild or in trade in the United States were found. The Florida Fish and Wildlife Conservation Commission has listed the tilapia Alcolapia grahami as a prohibited species. Prohibited nonnative species (FFWCC 2018), “are considered to be dangerous to the ecology and/or the health and welfare of the people of Florida. These species are not allowed to be personally possessed or used for commercial activities.” Means of Introductions in the United States No records of Alcolapia grahami in the United States were found. 1 Remarks From Bayona and Akinyi (2006): “Vulnerable D2 ver 3.1” Various sources use Alcolapia grahami (Eschmeyer et al. 2017) or Oreochromis grahami (ITIS 2017) as the accepted name for this species. Information searches were conducted under both names to ensure completeness of the data gathered. 2 Biology and Ecology Taxonomic Hierarchy and Taxonomic Standing According to Eschmeyer et al. (2017), Alcolapia grahami (Boulenger 1912) is the current valid name for this species. It was originally described as Tilapia grahami; it has also been known as Oreoghromis grahami, and as a synonym, but valid subspecies, of -

Tracing Community Conservation Evolution, Power Relations and Sustainability in Northern Kenya
MSc. BIODIVERSITY, CONSERVATION AND MANAGEMENT TRACING COMMUNITY CONSERVATION EVOLUTION, POWER RELATIONS AND SUSTAINABILITY IN NORTHERN KENYA CANDIDATE NUMBER: 142504 DATE DUE: 3rd SEPTEMBER 2012 WORD COUNT: 15,333 Abstract Candidate No. 142504 Abstract The narrative of Fortress Conservation was based on strategies dominated by attempts to reserve places for nature, to separate humans from nature, and to prevent consumptive use or other forms of human impact. The counter-narrative of Community Conservation promises to reconcile conservation and development objectives, and ensure the interests of the local people are taken into account. This narrative is no panacea however, and in the evolution of community conservation in Kenya, several initiatives have fallen victim to poor governance or the lack thereof, or worse, the retrogression into the colonial model of conservation through exclusion. A new model of community conservation in Kenya is emerging, distinguished by the governance and leadership of umbrella bodies and land owner associations, state involvement and community buy-in in a new frontier of conservation on communal lands. This new model is reordering power relations and endeavours to foster socio-ecological resilience for and by communities. 2 Table of Contents Candidate No. 142504 Table of Contents Abstract……………………………………………………………………………………….. 2 Table of Contents……………………………………………………………………………. 3 List of Tables and Figures………………………………………………………………….. 5 Acknowledgements…………………………………………………………………………...7 Introduction……………………………………………………………………………………..8 Literature Review a) The amorphous entity of ‘Community’……………………………………………..10 b) Community Conservation: The genesis of the narrative………………………….11 c) Early days: Kenya’s governance history in its infancy…………………………....13 d) Disentangling the values and narratives behind community conservation in Kenya……………………………………………………………………………………17 e) Power relations and their role in community conservation…………………….….18 f) The Scorecard: can community conservation get it right? ............................... -

H. BAKER, B.Sc, F.G.S. Geologist 165^G FOREWORD The publication of the report on the geology of the area south of Magadi completes the account of the southern end of the Rift Valley as it occurs in Kenya. The Magadi area itself was described by Mr. Baker in Report No. 42 (1958). During the mapping of the continua tion of the Magadi area the discovery of some critical exposures enabled the correction of an error of succession in the lower Pleistocene rocks that had been made during the survey of the Magadi area. The area is wild and desolate, but of considerable interest scenically, with the western Rift wall a little beyond its west boundary, rugged hills of ancient rocks in the south-east and two prominent volcanoes, Lenderut and Shombole, rising from the Rift floor. -

Rift valleys are found both on land and at the bottom of the ocean, where they are created by the process of seafloor spreading. Rift valleys differ from river valleys and glacial valleys in that they are created by tectonic activity and not the process of erosion. Tectonic plates are huge, rocky slabs of Earth's lithosphere—its crust and upper mantle. Tectonic plates are constantly in motion—shifting against each other in fault zones, falling beneath one another in a process called subduction, crashing against one another at convergent plate boundaries, and tearing apart from each other at divergent plate boundaries. Many rift valleys are part of “triple junctions,” a type of divergent boundary where three tectonic plates meet at about 120° angles. Two arms of the triple junction can split to form an entire ocean. The third, “failed rift” or aulacogen, may become a rift valley. -
Lake Natron Soda Ash Draft ESIA
Chapter 3 - Lake Natron Soda Ash ESIA 3 - 6 The Act has wide ranging powers; of direct relevance to this EIA are the following Sections: • Section 47-49 allows for the proclamation of environmental planning areas which would be managed by the Environmental Council and for which an environmental management plan would be prepared. • Section 51 allows for the minister to declare an Environmentally Sensitive Area. • Section 56 allows for the declaration of an area as a protected wetland. • Sections 106 – 113 state that it is an offence to emit pollutants, emit noise or discharges in excess of the standards prescribed. • Section 141 requires any person undertaking an activity to comply to environmental standards and criteria. • Section 151 allows the Council to require any person to reinstate the environment to a state as near to the original as possible. • Section 178 ensures the public right to environmental information and to participate in decision making. 3.3.2 Environmental Impact Assessment Guidelines and Audit Regulations (2005) The guidelines provide the legislative framework for the impact assessment process from screening of project to review. Report format and qualifications of parties to conduct an ESIA are well elaborated. 3.3.3 Wildlife Conservation Act (1974) The principal legislation governing wildlife utilization in Tanzania is the Wildlife Conservation Act of 1974. This Act provides the Director of Wildlife with powers to oversee the overall management of wildlife in the country. The Director is in charge of game reserves, game conservation areas, and open lands, while the Tanzania National Parks Authority (TANAPA) is in charge of the national parks (Lawyers' Environmental Action Team (LEAT). -
