Clean / honest truths on the Internet - Bok av Jawhar Jammoussi - Häftad

Sociology professors have predicted that the intense use of the Internet will have different and heavy impacts on states, on society and on the individual. This is what has completely changed the essence of social interaction that produces authority in almost all societies around the world. It seems therefore that this latent social movement has irrevocably brought about acute changes in the sub-system of Power in its different typologies and in its different relations with Authority within society..

Hydrological risk analysis in three Douala districts - Bok av Casimir Pascal Kamgho Kamsu - Häftad

Hydrological risk analysis in three Douala districts - Bok av Casimir Pascal Kamgho Kamsu - Häftad

During the rainy season, many neighborhoods in the city of Douala are affected by flooding and rising capillarity. Poor neighborhoods such as Nkolmintag, Nylon and Tergal are among the worst affected. These life-threatening phenomena are inherent to the characteristics of the physical environment. In other words, flooding and rising capillarity tend to develop dangerously in this area due to heavy rainfall, the site's flat topography, sandy-clay or sandy-loam soils and dense drainage.

Massive land trade: the new monopoly - Bok av Charlotte Lallement - Häftad

Massive land trade: the new monopoly - Bok av Charlotte Lallement - Häftad

While the massive trade of agricultural land is decried by NGOs and often considered as a land grab, international organizations such as the World Bank see it as a development opportunity for countries selling or leasing their land, what they call the \win-win\ principle. However, this commercialization of land seems to have heavy repercussions on local populations, and progress in terms of development is hardly visible. Is the massive trade in agricultural land really a development opportunity?..
