Vector-borne diseases are highly sensitive to environment and to environmental changes. Rift Valley Fever (RFV) is a mosquito-borne zootic virus associated with severe diseases in human beings and economic consequences to livestock sector. Animal and human movements have a fundamental impact on RVF transmission. In recent years, there has been a growing interest in the use of mathematics and agent based models to represent and analyze the dynamic of RFV transmission. However, no previous study has taken into consideration animal herds' mobility and precipitation factors to understand the disease spread. This limitation underlines the necessity to use computational model approach based on multi-agent system in the study of vector-borne diseases transmission and diffusion. In this paper, a multi-agent system combining conceptual model expressiveness is used to study animal herds' mobility and the precipitation parameter impact on the Rift Valley Fever outbreak in Ferlo Barkedji in Northern Senegal. Simulation scenarios with various parameters, including rain quality, hosts, vectors, camp dispersal around ponds, etc., are unrolled. The different results we have obtained show that the evolution of the number of infected hosts and infected vectors depend on the degree of animal herds' mobility and on precipitations. Our model provides a framework that permits predicting the spread of the disease associated with the mobility of animal herds.

“…This result is compatible with the literature for various zones in Niger, including the Damagaram where Zermou is located, but also other arable places in Niger for the end of the first half and the beginning of the second half of the 20th century. This conquering behavior is usually described as a response to manpower scarcity but also as an ''investment for the future'' at family and village levels (Demont et al, 2007;Bah et al, 2006). Even with lower land occupation growth rates at Gabi and the Fakara, 60 years of continuous growth eventually led to all potential cropland being cropped.…”

a b s t r a c tThe aim of this article is to analyze the impact of development interventions on the population of three Nigerien villages that differ in terms of their agro-ecological, social and economic characteristics. This is performed by simulating the behavior of individuals in an agent-based modeling framework which integrates the village characteristics as well as the family internal rules that condition access to economic and production activities. Villagers are differentiated according to the social and agro-ecological constraints they are subjected to. Two development project interventions are simulated, assuming no land scarcity: increasing the availability of inorganic fertilizers for farmers and an inventory credit technique based on millet grain. Two distinct approaches were used to model the rationale of farmers' decision making: gains or losses in economic value or gains or losses in within-village ''reputation''. Our results show that village populations do not respond en masse to development interventions. Reputation has little effect on the population behavior and should be considered more as a local proxy for wealth amongst villagers, suggesting the monetization of these societies. Populations involve themselves in the two simulated development interventions only at sites where savings are possible. Some level of household food security and investment capacity is actually required to take part in the development interventions, which are largely conditioned by family manpower and size. As long as uncultivated land remains available in the village territory, support for inorganic fertilizers has little impact in the absence of any intensification process. Inventory credit engages a maximum of 25% of the population at the site with medium agro-ecological conditions. Therefore, both interventions should be viewed as a potential support tool for a limited part of the population capable of going beyond the survival level, but not as a generic poverty-alleviation panacea.

The artificial society modeling approach for studying the behavior of complex systems has gained wide applications in recent years. The integration of this approach with geographical theories provides an inter-disciplinary approach to the study of complex human-nature interactions. By deploying widely applied RePast and Eclipse as basic tools, this study develops an artificial society model that is able to capture the characteristics of geographical systems. Consequently, DLA (diffusion limited aggregation) algorithms are applied to generate and record each agent's pathway. The simulated results demonstrate that the transportation networks produced with DLA algorithms have a spatial pattern very similar to the form of urban areas exhibited in real world.
