Mécanisation, productivité du travail et risques : le cas du Burkina Faso

In western Burkina Faso there is an extension of mechanised farms. This evolution generates an increase in cotton and food productions mainly because of an extension or cultivated areas. At the same time the burden of work goes up especially during harvesting. Such a technology allowed a rise in monetary incomes per farm for small animal traction farms an particulaly for large animal traction farms and motorized farms. The monetary incomes per person largely increase when farmers get animal traction but they increase just a little when farmers buy a tractor. The naturals risks and the economic risks are high and impede the farmers from investing. Farmers who develop monetary exchanges are especially exposed to these risks. Such a context encourage extensive strategies and contribute to the development of securised crops like cotton. The non-agricultural activities development which is able to promote a monetary resources diversification remains low. Saving which really belongs to an anti-risks strategy is not very developed.
