With the increase of greenhouse effect gas emissions, caused by human activities, climate change impacts on environment and economic activities, especially agriculture in developing countries, remain currently an international concern. In Burkina Faso, the share of the agriculture sector to the real GDP is the largest historically and represented 44% in 2016. Furthermore, this sector remains heavily dependent on climatic conditions. With regard importance to these facts, the objective of the present study is to analyze the vulnerability of the agricultural sector, mainly the production of maize, millet, sorghum and rice in Burkina Faso to the effects of climate change. To test the hypothesis whether "climate variables, such as rainfall and temperature have a positive impact on cereal production," a linear model was estimated by the stepwise method on panel data. The results show that increased precipitation would result in an increased production of maize, millet and sorghum and decreased that of rice. While an increase in temperature contributes to a decrease of the latter. Thus, the impact of climate change on agriculture is real in Burkina Faso and the adoption of effective adaptation and mitigation is of great importance.

The objective of this article is to analyze the factors explaining the choice of Burkinabè producers as to the number of adaptation strategies to be adopted. Following the country's agro-climatic breakdown, four provinces were selected for data collection and 559 households were surveyed. These include the Yatenga province in the Sahelian zone, the provinces of Nayala, Namentenga in the Sudano-Sahelian zone and finally the Houet province in the Sudanese climate. Estimations from the multinomial logit model show that the number of assets, the access to information on climate, group appartenance, the use of hired labor, possession of manure pit and rainfall are the factors that determine the adoption of a number of adaptation strategies. Thus, activities toward the capacicity building based on these results will contribute significantly to the increase of the producers' resilience and reduce the vulnerability of the agricultural sector to climate change.

The impact of economic and trade expansion of China on Burkina Faso's economy is analyzed in this work through three channels: trade in goods and services, foreign direct investment and development assistance. To capture the direct and indirect effects of Chinese growth, we use a computable general equilibrium model. The results show that expanded trade with China leads to an increase in domestic prices, an increase in exports to China among product categories for which exports increases, and an increase in imports. The effect on growth, value added ad household wellbeing is small. We find a decline in domestic prices, an increase in exports and a decline in imports. Higher FDI inflows induce additional economic growth equal, increased total labour demand and increased average household well-being, especially among cotton farmers.
