  • Convention on the Conservation of Migratory Species of Wild Animals
    Convention on the Conservation of Migratory Species of Wild Animals Secretariat provided by the United Nations Environment Programme STOP DUCKING HARD FACTS AND TOUGH POLICY OPTIONS ON BIRD FLU, SAYS NEW SCIENTIFIC TASK FORCE International Scientists warned today against panic responses based on the assumption that wild birds are the only cause of avian flu, and called for • regulation of animal markets • global surveillance of avian influenza in wild birds • precautionary suspension or restriction of the global wild bird trade • improved standards in poultry farms, farming and marketing practices and enhanced quality control of animal vaccines • identification of the precise migratory routes of waterbirds and the highest risk location along different flyways. The Task Force, comprising representatives and observers from 9 different international organizations including 4 UN bodies, also seeks much better data and information on the cause of the spread of the disease. It warned that several globally endangered species of birds could be wiped out by the killer disease, including the Lesser White-fronted Goose, Red-breasted Goose, Barheaded Goose, Swan Goose, Oriental Stork and Siberian Crane. Bonn, October 24 – A new task force on avian influenza comprising scientists and conservationists, convened by the UNEP Convention on Migratory Species (CMS), called today for urgent action to combat the root causes of the outbreak. It warned against growing hysteria and a “one-eyed” approach in the media which grossly over-simplifies the causes of the flu outbreak, and the methods needed to counter-act it in the interests of human and animal health. They emphasized the uncertainty of knowledge on key issues including how the virus is transmitted between domestic and wild birds.

In the world context, colonialism had very heterogeneous effects, operating through many mechanisms, sometimes encouraging development sometimes retarding it. In the African case, however, this heterogeneity is muted, making an assessment of the average effect more interesting.

  • THE ACQUISITION of SLAVES Portuguese Exploration in The
    CHAPTER TWO THE ACQUISITION OF SLAVES Portuguese exploration in the Atlantic in the fifteenth century her- alded a shift in emphasis in the African slave trade from the Sahara to the West African coast. As outlined in the Introduction, the slave trade focused first on Arguim and Elmina, but during the late six- teenth century Upper Guinea developed as the main centre of the trade. Meanwhile in the early seventeenth century the conquest of Angola laid the basis for the development of the slave trade in that region. It was thus during the period of the Portuguese asientos that Upper Guinea began to lose its dominance in the trade to Angola. Manuel Bautista Pérez acquired slaves from both Upper Guinea and Angola. He was personally involved in the acquisition of slaves in Upper Guinea on two slave-trading expeditions to the Coast between 1613 and 1618, but as far as we know he never visited Angola. Following these two expeditions he settled in the Indies and largely relied on agents in Cartagena to acquire slaves for him. Between 1626 and 1633 his agents in Cartagena purchased 2,451 slaves of which 48.4 percent came from Upper Guinea and 45.8 percent from Angola.1 Pérez’s early expeditions to the African coast were a learning process for the young slave trader and they gener- ated a considerable volume of papers that included not only trad- ing accounts but also many private letters. The evidence contained in these documents adds considerable detail to what is known about slave-trading operations on the Upper Guinea Coast in the early seventeenth century from the general observations of merchants, trav- ellers and missionaries.

December 2020 / Printed: June 2021 Abstract.The Maguari Stork (Ciconia maguari) occurs extensively in South America where it inhabits mainly wetlands. Despite being common in some regions, information on several aspects of its ecology is lacking. The objective of this study was to investigate the diet of Maguari Storks in the Pampa ecoregion of southern Brazil using citizen science. A compilation of records of foraging birds was done in two on-line databases - WikiAves and e-Bird Brasil. A total of 36 records, obtained by citizens between 2008 and 2020, reported storks holding preys with their bills. The most frequent food item was the muçum fish (Synbranchus marmoratus), representing 39% of the preys. Squamate reptiles and anuran amphibians comprised 33% and 19% of the food items, respectively. Most preys had a serpentiform body shape, being represented mainly by muçum and snakes. This study suggests that our knowledge regarding the natural history of Brazilian birds can increase through citizen science.

  • Was the Gold Coast 'Decolonised' Or Did Ghana Win Its Independence?
    Was the Gold Coast ‘decolonised’ or did Ghana win its independence? A resource for Key Stage 4 Key words: Empire, Liberty, Government, Ideas, Role of individuals in encouraging change, Africa, independence, decolonisation, nationalism, Ghana, Nkrumah In 1957 the British colony of the Gold Coast became the independent nation of Ghana. Did Britain grant Ghanaian independence or was this the result of the actions of Ghanaian nationalists, led by Kwame Nkrumah? Many historians see the post-World War Two period as one of British retreat from its empire. Britain was economically weakened and in debt to the United States, which opposed continued European colonialism. Although India achieved independence in 1947, Britain initially sought to compensate for the loss of its Asian colonies with increased economic intervention in its African ones: it also trained a new generation of African civil servants to replace their British counterparts. This has been characterised as a ‘second colonial occupation’. Influenced by the Universal Declaration of Human Rights and the new United Nations, Britain was committed to decolonisation when African colonies were ready to rule themselves, but this was commonly imagined as taking 20, 30 or even 50 years. Meanwhile, a new generation of African nationalists wanted to mobilise a mass movement against colonialism, criticising older African political leaders who sought reform within colonialism rather than its overthrow. Kwame Nkrumah, who returned from studies in the US and Britain to the Gold Coast in 1947, supported protests by poverty- stricken ex-soldiers who had fought for Britain in WWII. In February 1948, these demonstrators were fired upon by British troops and riots broke out across the territory.
