| Two case studies are presented in which models were used as focal tools in problems associated with common-pool resource management in developing countries. In the first case study, based in Zimbabwe, Bayesian or Belief Networks were used in a project designed to enhance the adaptive management capacity of a community in a semiarid rangeland system. In the second case study, based in Senegal, multi-agent systems models were used in the context of role plays to communicate research findings to a community, as well as to explore policies for improved management of rangelands and arable lands over which herders and farmers were in conflict. The paper provides examples of the use of computer-based modeling with stakeholders who had limited experience with... |

| Abstract Background Although considered a public health issue in Senegal, the actual incidence and mortality from snakebite are not known. In the present study, an epidemiological survey was carried out in Kédougou region, southeastern Senegal, where envenomations, particularly by Echisocellatus, are frequent and severe. Methods Three sources of data were used: records from health centers and reports by health professionals; traditional healers; and household surveys. Results The annual incidence and mortality provided by health centers were 24.4 envenomations and 0.24 deaths per 100,000 population, respectively. The annual incidence recorded by traditional healers was 250 bites per 100,000 inhabitants, but the number of deaths was unknown. Finally,... |

| In agriculture, the coexistence of different forms of land tenancy or labour contract has been explained so far by several theories related to Marshallian inefficiency, incentives, risk sharing, and transaction costs, including supervision costs. These theories and the empirical evidences have greatly contributed to explain the reasons behind land tenancy or labour contract choice. This study follows up on this. Moreover, it intends to take a further step by focusing particularly on the production technologies at plot level, and by designing and testing a theoretical model based on household profit optimization. This model will take into account the supervision costs of labour (i) to compare optimum profit derived from plots based on household labour, a... |

| Much has been written to show the importance of diversification for rural African households because of the considerable share of non-farm revenues in total income (Reardon, 1997; Reardon et al., 1998). The literature points out push and pull factors explaining that risk and adverse shocks which characterize farm activities urge rural population to diversify into more profitable non-farm activities. But less attention has been paid to the distinction between two diversification patterns, namely local diversification and migration, and their relationship. Drawing on the theoretical and empirical literature, we identify the advantages and drawbacks of local diversification versus migration decision in terms of expected pay-offs for the family and the... |

| Ocean grabbing occurs when traditional users, such as small-scale fishers, are pushed aside by new development activities. This grabbing must be prevented to avoid sea uses that maintain or increase social inequity. In this paper, we show that in tropical Atlantic countries, such as Brazil and Senegal, examples of ocean grabbing already occur. In this context, we analyse if Maritime Spatial Planning (MSP) may be an opportunity to limit ocean grabbing or, to the contrary, poses a risk to increase it. MSP calls for an ecosystem approach that requires integrated coastal and marine management and involves stakeholders in developing a shared vision of the future, where society and environment are preserved. However, recent studies have shown that MSP is a... |

| The study was carried out at two sites, the island of Carabane, near the ocean, and the village of Djivent, 60 km by water-way from the mouth of the Casamance River. On the first site, the rise of water temperature commands the spat fall from March to October with a maximum peak in July. Because of a heavy biological competition, oysters can only survive within the intertidal zone. On the second site from August to November, which corresponds with the end of the rainy season, the decrease of salinity induces spawning and settlement of young oysters. Because of the heavy salinity variations there is a weak biological competition and young oyster can easily survive in permanent immersion as within the intertidal zone. On both sites, the growth is linear but... |

| A new species of Platypodiella Guinot, 1967, from the island of St. Helena, P. georgei spec, nov., is described. This species was found associated with encrusting species of Palythoa Lamouroux, 1816 (Zoantharia). Ample evidence is presented that both the eastern Atlantic P. picta (A. Milne-Edwards, 1869) and the western Atlantic P. spectabilis (Herbst, 1794) also live habitually associated with encrusting species of Palythoa, rarely with other zoantharians. For each of the two East-Pacific members of the genus, P. rotundata (Stimpson, 1860) and P. gemmata (Rathbun, 1902), there is at least one rather detailed published record suggesting that these species too associate with Palythoa. Thus, this habit would seem to go for all five members of the genus. Data... |
