STRATEGIES TO SURPASS THE VULNERABILITY OF THE SMALL ISLAND STATES WITH FEW RESOURCES: THE CASE OF CAPE VERDE

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 Barbados’s 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.

Alfabetização de crianças caboverdianas em língua portuguesa como língua não materna : o ensino da leitura

abstract: Cape Verde is a country of bilingual characteristics, where coexist two languages: the mother tongue – the Creole of Cape Verde (CCV) or the Capeverdian Language (LCV) and the Non Maternal language – the Portuguese that is the official language and, therefore, the language used in the process of education and learning. This situation generates conflicts so much to linguistic level as to cultural level. The two languages presents some lexical resemblances, what drives, many times, to misconceptions and linguistics errors that complicate children in the learning, in particular, of reading that constitute the base for the learning of others knowledge. The learning of reading, in the Non Maternal language, requires a development of the oral language in Portuguese Language, which stimulates the reasoning of the child through playful exercises and cognitivists and construtivists approaches. In this way, the competences of phonological processing in the acquisition of the competences of reading are important for the discrimination of written text and favor the learning and the development of reading. The child, through the discovery, begins to elaborate concepts in the way to obtain a relation with the written language, by functional form. Adopting a methodology of case study and through questionnaires, direct observation and collect of documentary information, this dissertation presents and analyzes connected aspects to the literacy of capeverdian children in the beginning of the schooling and to the learning of reading as basic support for the learning of Non Maternal language. The subsidies collected by the study, presented in this dissertation will contribute for the education progress of reading and, also, for implement successfully the learning of reading of the students, developing to practical of reading and the expectations in uncover the multiplicity of the dimensions of experience in that domain and contribute for a relative comprehension of written and reading modes.

O texto literário na aula de português L2: uma proposta de didactização: Vida e morte de João Cabafume, de Gabriel Mariano

Na concepção deste trabalho, que tem como tema O texto literário na aula de Português L2 – Uma proposta de didactização: Vida e Morte de João Cabafume, de Gabriel Mariano, procurámos investigar e reflectir sobre a abordagem do texto literário no 3º ciclo do ensino secundário cabo-verdiano, especificamente na aula de Português L2, nas áreas de estudos Científica e Tecnológica e Económica e Social, do 11º ano de escolaridade, seguida da apresentação, a título de exemplo, de uma proposta de didactização do texto acima mencionado, na perspectiva da utilização do texto literário como material em que o uso estético da língua potencia a dimensão plural da significação. Para a consecução dos objectivos propostos, procurámos dar visibilidade, na perspectiva da leitura do texto literário, às orientações do programa, às potenciais práticas pedagógicas no ensino de narrativa literária, incluindo os métodos de ensino, os recursos utilizados pelos professores, a forma como os alunos encaram todo o processo de leitura do texto literário em que está envolvido. No entanto, para a concepção da proposta de didactização, procurámos cruzar propostas metodológicas de modelos de leitura e métodos de ensino do texto narrativo e de línguas defendidos por vários autores do campo da didáctica da literatura e das línguas, cujos princípios assentam em bases que valorizam a interacção entre o texto e o leitor. Partindo de um conto de Gabriel Mariano, escritor cabo-verdiano, Vida e Morte de João Cabafume, tentámos propor um roteiro de leitura adequada do texto narrativo, de forma a conduzir o aluno não só na leitura do contexto narrativo, como também na compreensão da dimensão plural da língua enquanto material estético, procurando desenvolver, fundamentalmente, as suas atitudes, os valores éticos e morais e, num âmbito complementar, as suas competências da escrita e da oralidade. Palavras-chave: Texto Literário, Leitura, Escrita, Oralidade, Português L2.

Erosão dos solos em Cabo Verde - Estudos dos Processos e Quantificação de Três Bacias na Ilha de Santiago

L’archipel du Cap Vert constitué de 10 îles volcaniques appartient à la zone sahélienne qui s’étend de l’atlantique jusqu’à la mer rouge. Depuis, plusieurs décennies le Cap Vert est affecté par la désertification causée en grande partie par la récession climatique et l’érosion des sols. Ces facteurs, associés à la forte pression anthropique sur les ressources, à l’orographie accidentée et à des pluies tropicales parfois diluviennes, provoquent de sérieuses pertes du patrimoine foncier. Cependant, depuis son Indépendance en 1975, le Gouvernement a mené un vaste programme d’arborisation, de restauration des terres et d’aménagement des cours d’eau. Pourtant, très peu de recherches ont été menées pour évaluer les actions de protection et de conservation des sols et des eaux. Par conséquent, il n’existe quasiment pas de données sur la problématique de la dégradation des terres ni de bilans. Dans le cadre de ce travail, nous avons étudié les différents facteurs qui contrôlent l’érosion hydrique des sols. Nous avons plus particulièrement cherché à différencier les effets des activités humaines, notamment agricoles, de ceux des facteurs climatiques comme les précipitations et la génération des écoulements. Nous avons également établi les premiers bilans d’exportations de matières en suspension et en solution dans le contexte de l’archipel du Cap Vert. L’étude a été menée à l’échelle de trois bassins versants de l’ile de Santiago Cap-Vert. Ces trois bassins versant (Longueira, Grande et Godim) sont localisés dans la partie centrale de l’île de Santiago et représentatifs des divers modes d’occupation du sol et des différents climats de l’île. Il existe un gradient climatique entre les trois bassins versants. En effet, Longueira qui présente une superficie de 4,18 km2, une pente moyenne de 47 %, se localise dans une zone humide couverte à 69 % par une forêt et une surface agricole de 17 %. Grande avec une superficie de 1,87 km2, se localise en zone sub humide pour une pente moyenne de 50 %, il est essentiellement agricole. Godim, avec une superficie de 2,0 km2, se localise en zone semi aride, il est particulièrement agricole et sa pente moyenne est de 32 %. Pour ces trois bassins versants, les écoulements de crue à l’exutoire ont été mesurés et échantillonnés de 2004 à 2009. Le bassin versant de Longueira a fait l’objet d’un suivi plus poussé, notamment en termes de fréquence d’échantillonnage et de suivi des écoulements hors crue. Sur chaque échantillon nous avons procédé à la détermination de la concentration des matières en suspension ainsi qu’à l’analyse des éléments majeurs. Les résultats obtenus montrent que l’érosion mécanique dans les 3 bassins versants est caractérisée par une forte variabilité spatiale et temporelle. Sur la période 2005-2009, le bilan moyen annuel pour les bassins versants de Longueira, Grande et Godim est de : 4266, 157 et 10,1 t.km2.an-1 respectivement. La saison humide 2006 a été la plus érosive pour l’ensemble des trois bassins versants et particulièrement dans Longueira avec 2 crues exceptionnelles qui ont généré une concentration moyenne de matières en suspension supérieure à 100 g/l. En revanche, les saisons 2005 et 2008 ont été dans l’ensemble peu érosives car les concentrations moyennes ne dépassèrent pas 20 g/l. Par ailleurs, il n’y a pas eu de lames d’eau écoulées pour les saisons 2005 et 2007 pour le bassin de Godim. Sur le bassin de Longueira, l’étude des phénomènes d’hystérésis permet de caractériser chaque crue et de montrer que l’évolution temporelle des exportations de matières en suspension au cours de la saison est fortement influencée par les activités agricoles. En effet, la première crue provoque l’exportation massive des sédiments disponibles et localisés dans le lit du cours d’eau. En conséquence, la seconde est moins exportatrice de sédiments. Un mois après les premières pluies, les activités de sarclage diminuent la densité du couvert végétal et destructurent la partie superficielle des sols, ce qui provoque à nouveau une très forte exportation de sédiments lors de la troisième crue. Les résultats de l’érosion chimique sur le bassin de Longueira indiquent que le taux d’érosion chimique moyen s’élève à 45 t.km2.an-1 avec une forte variabilité temporelle. En effet, les saisons les plus humides de 2006 et 2007 sont les plus exportatrices de matières en solution, alors que 2005 a eu une faible exportation. L’utilisation du modèle de mélanges EMMA (End-Members Mixing Analysis) montre que les écoulements hypodermique et profond, qui alimentent le cours d’eau en éléments dissous, sont les principaux facteurs de l’érosion chimique. On montre ainsi que les écoulements hors crue sont à l’origine de plus de 90% des flux d’érosion chimique. L’écoulement superficiel, qui contribue à environ 70 % du débit du cours d’eau en crue, constitue un facteur de premier plan de l’érosion mécanique des sols.
