The problem of small Island Developing States (SIDS) is quite recent, end of the 80s and 90s, still looking for a theoretical consolidation. SIDS, as small states in development, formed by one or several islands geographically dispersed, present reduced population, market, territory, natural resources, including drinkable water, and, in great number of the cases, low level of economic activity, factors that together, hinder the gathering of scale economies. To these diseconomies they come to join the more elevated costs in transports and communications which, allies to lower productivities, to a smaller quality and diversification of its productions, which difficult its integration in the world economy. In some SIDS these factors are not dissociating of the few investments in infrastructures, in the formation of human resources and in productive investments, just as it happens in most of the developing countries. In ecological terms, many of them with shortage of natural resources, but integrating important ecosystems in national and world terms, but with great fragility relatively to the pollution action, of excessive fishing, of uncontrolled development of tourism, factors that, conjugated and associated to the stove effect, condition the climate and the slope of the medium level of the sea water and therefore could put in cause the own survival of some of them. The drive to the awareness of the international community towards its problems summed up with the accomplishment by the United Nations in the Barbadoss Conference, 1994 where the right to the development was emphasized, through the going up the appropriate strategies and the Programme of Action for the Sustainable Development of the SIDS. The orientation of the regional and international cooperation in that sense, sharing technology (namely clean technology and control and administration environmental technology), information and creation of capacity-building, supplying means, including financial resources, creating non discriminatory and just trade rules, it would drive to the establishment of a world system economically more equal, in which the production, the consumption, the pollution levels, the demographic politics were guided towards the sustainability. It constituted an important step for the recognition for the international community on the specificities of those states and it allowed the definition of a group of norms and politics to implement at the national, regional and international level and it was important that they continued in the sense of the sustainable development. But this Conference had in its origin previous summits: the Summit of Rio de Janeiro about Environment and Development, accomplished in 1992, which left an important document - the Agenda 21, in the Conference of Stockholm at 1972 and even in the Conference of Ramsar, 1971 about Wetlands. CENTRO DE ESTUDOS AFRICANOS Occasional Papers CEA - Centro de Estudos Africanos 4 Later, the Valletta Declaration, Malta, 1998, the Forum of Small States, 2002, get the international community's attention for the problems of SIDS again, in the sense that they act to increase its resilience. If the definition of vulnerability was the inability of the countries to resist economical, ecological and socially to the external shocks and resilience as the potential for them to absorb and minimize the impact of those shocks, presenting a structure that allows them to be little affected by them, a part of the available studies, dated of the 90s, indicate that the SIDS are more vulnerable than the other developing countries. The vulnerability of SIDS results from the fact the they present an assemblage of characteristics that turns them less capable of resisting or they advance strategies that allow a larger resilience to the external shocks, either anthropogenic (economical, financial, environmental) or even natural, connected with the vicissitudes of the nature. If these vulnerability factors were grouped with the expansion of the economic capitalist system at world level, the economic and financial globalisation, the incessant search of growing profits on the part of the multinational enterprises, the technological accelerated evolution drives to a situation of disfavour of the more poor. The creation of the resilience to the external shocks, to the process of globalisation, demands from SIDS and of many other developing countries the endogen definition of strategies and solid but flexible programs of integrated development. These must be assumed by the instituted power, but also by the other stakeholders, including companies and organizations of the civil society and for the population in general. But that demands strong investment in the formation of human resources, in infrastructures, in investigation centres; it demands the creation capacity not only to produce, but also to produce differently and do international marketing. It demands institutional capacity. Cape Verde is on its way to this stage.

Esta tese centra-se em aspectos relevantes do ingls como uma lngua universal, no actual contexto globalizado e examina possveis mudanas relacionadas com o seu uso, em especial no continente africano, particularmente no caso de Cabo Verde, no sentido de ponderar eventuais alternativas nas pedagogias lingusticas no ensino desta lngua que impliquem uma adaptao realidade contempornea. Uma vez que, nos nossos tempos, o ingls a lngua de eleio para a comunicao intercultural entre povos com vrias experincias culturais e lingusticas, o conhecimento deste idioma torna-se, a cada dia que passa, impretervel e indispensvel, na interaco intercultural. Em frica, as funes desempenhadas pelo ingls so complexas; alm da lngua inglesa ser usada para comunicao entre etnias, com o estatuto de lngua franca, tambm tem o papel de preservar a identidade nacional e de estabelecer a unidade entre os povos da mesma nao. Por conseguinte, de considerar talvez ainda com mais pertinncia, a adopo de uma nova filosofia de pedagogia de ensino que permita dotar os seus cidados de capacidades que lhes possibilitem comunicar de forma inteligvel com povos de outras culturas e lnguas. O primeiro captulo aborda aspectos tericos relacionados com a expanso, comunicao e mudana associadas lngua inglesa e suas implicaes no ensino em pases onde esta no lngua nativa (L1). O segundo captulo reflecte, em primeiro lugar, sobre a situao lingustica em frica e as lnguas francas predominantes no continente, incluindo a lngua inglesa. Considera tambm questes relacionadas com o multilinguismo e a identidade, bem como assuntos relacionados com as implicaes da diversidade lingustica para a educao dos povos africanos.

Cabo Verde um pas com algum potencial no sector do agronegcios, representando cerca de trinta porcento (30%) dos rendimentos da populao rural. Muito tem sido feito para melhorar este sector, contudo, devido falta de espao e de pastos, vem buscando alternativas mais viveis para a criao de animais, que ocupam menos espao e que produzam mais por m2. O nmero de aves domsticas em Cabo Verde foi estimada em 431.194, desses noventa e quatro porcento (94%) representava a criao de galinhas. A ilha de Santiago foi a maior produtora com quarenta e sete porcento (47%) dos efetivos, em seguida a ilha de So Vicente com vinte porcento (20%). Temperatura, instalaes, nutrio e o manejo so variveis importantes para o bem-estar animal e devem ser encarados em sinergia. Quando no esto de acordo com as necessidades mnimas exigidas levam as aves para fora da zona de conforto. A temperatura ideal para a criao de galinhas poedeiras na fase de produo deve rondar os 17 C e os 28C, e nos primeiros dias de vida de 33C a 35C. Em Cabo Verde ainda no existe a preocupao em proporcionar condies ideias para as aves de criao, visto que ainda feita, na sua grande maioria, de forma tradicional e com pouca ou nenhuma tecnologia que vise um melhor desempenho produtivo das aves. Este trabalho teve como objetivos especficos: Monitorizar o consumo de rao por aves; Registar a postura diria e determinar a produo/produtividade; Analisar os factores que afectam a produo/produtividade de ovos no avirio do INIDA;

This paper presents the assessment and mapping of the Ribeira Seca catchment, an insular Sahelian mountain region sensitive to desertification, located on the island of Santiago, Cabo Verde. Desertification is a threat to the global environment, representing a serious ecological problemin Cabo Verde. To successfully combat desertification, an evaluation of desertification consequences is required and the building of cartography of the sensitivity for arid and semi-arid ecosystems is required as a first step. The MEDALUS model was the basis for this study in which six quality indicators were used: climate, soil, vegetation, land management, erosion and social factors. Several parameters were defined for each indicator with weights varying between 1 (very low) and 2 (very high). The geometric mean of each of the six quality indicators was employed to produce a map of areas sensitive to desertification. The results of this study show that more than 50% of the watershed show clear evidence of becoming a desertified area.

The pattern of genetic variation of the lizard Mabuya maculilabris from So Tom Island (Gulf of Guinea) was investigated using a combination of three mitochondrial DNA gene fragments. Forty-eight haplotypes were recovered among 66 individuals covering the whole island. The genealogy inferred from the most parsimonious network of haplotypes allows us to detect two main and long branches departing from the putative group of oldest haplotypes. The tips of these branches exhibit star-like phylogenies, which may indicate of recently expanded populations, most probably from a small number of founders. A nested clade analysis suggests a complex pattern of past events that gave rise to the extant geographical pattern found in the haplotype distribution: past and allopatric fragmentation, range expansion, restricted gene Xow and long-distance dispersal. These results are consistent with the complex geological history of the island where important volcanic activity with extensive lava Xows has occurred during several periods. Mismatch- distribution analysis and AMOVA also support these conclusions. Substantial genetic structuring among these lizards was detected as well as high levels of diVerentiation between the southern edge populations (particularly those from the Rolas Islet) and the remaining ones. However, variation is low relative to the geological age of the island. Our results indicate that patterns of variation observed in reptiles in other oceanic islands are not indicative of those observed in the islands of the Gulf of Guinea.
