Sustainable development is regarded today as a goal which has to be reached by all countries. Therefore cooperation for development is more than ever necessary to face the global challenges such as poverty, human health, food crisis etc. Cooperation is all the more crucial as the Millennium Development Goals (MDGs), adopted in 2000, are gaining consensus at the international level. To achieve this objective all countries have to commit themselves to creating a favourable and dynamic international economic environment. However the current financial and economic crisis is posing many constraints and difficulties to the achievement of the MDGs by the year 2015. The aim of this work is to analyse the concept of financial crisis by illustrating the causes and the consequences of the current crisis and its effects on the global economy with special reference to the situation in Tunisia.

Ticks (suborder Ixodida) are widespread in the world and infect many animal species, including camels. On the host, ticks are known for their dual effects: the first direct, since they are strictly haematophagous, and the second indirect, because they are implicated in the transmission of certain animal diseases. However, tick infestation depends on several factors related to the environment and to the host. Different epidemiological conditions favoring the spread of certain diseases are encountered in different camel-farming systems of southern Tunisia. In this respect, followed tick infestation for camels in different herding methods, with the aim of developing an adapted strategy against these parasites. This work describes field observations of infestations in extensive ranches and from monitoring daily infestations of animals raised in semi-extensive and intensive systems. Our observations show that ticks parasitizing camels in southern Tunisia belong to the genus Hyalomma. The degree of camel infestation by ticks varies with the farming methods. In ranching, the degree of infestation depends on the areas grazed: it is more intense on low and salty paths, but it is low on dry and stony paths. Monitoring the kinetics of infestations in semi-extensive rearing in camels using more or less humid paths shows that the number of ticks per animal can exceed 100 individuals, whose distribution on the body of the animal depends on the season and the thinness skin of the animal's skin. In the intensive system, the infestation of camels is very low or even absent. Source

Sustainable development strategies are regarded today as a tool to improve the living conditions and alleviate poverty of population, above all in rural areas. The aim of this work is to focus on the current state of sustainable development in Tunisia with a view to achieving the Millennium Development Goals (MDGs). To this end we shall analyze preliminarily some spatial data applied to a set of development indicators by means of the principal components analysis method (PCA) to highlight regional disparities at the governorate level and above all disparities between Tunisian coastal and inland regions.
