In this paper, the climate and environmental datasets were processed by the scripts of Generic Mapping Tools (GMT) and R to evaluate changes in climate parameters, vegetation patters and land cover types in Burkina Faso. Located in the southern Sahel zone, Burkina Faso experiences one of the most extreme climatic hazards in sub-saharan Africa varying from the extreme floods in Volta River Basin, to desertification and recurrent droughts.. The data include the TerraClimate dataset and satellite images Landsat 8-9 Operational Land Imager (OLI) and Thermal Infrared (TIRS) C2 L1. The dynamics of target climate characteristics of Burkina Faso was visualised for 2013-2022 using remote sensing data. To evaluate the environmental dynamics the TerraClimate data were used for visualizing key climate parameter: extreme temperatures, precipitation, soil moisture, downward surface shortwave radiation, vapour pressure deficit and anomaly. The Palmer Drought Severity Index (PDSI) was modelled over the study area to estimate soil water balance related to the soil moisture conditions as a prerequisites for vegetation growth. The land cover types were mapped using the k-means clustering by R. Two vegetation indices were computed to evaluate the changes in vegetation patterns over recent decade. These included the Normalized Difference Vegetation Index (NDVI) and the Soil-Adjusted Vegetation Index (SAVI) The scripts used for cartographic workflow are presented and discussed. This study contributes to the environmental mapping of Burkina Faso with aim to highlight the links between the climate processes and vegetation dynamics in West Africa.

Sustainable development goal 17 emphasizes the importance of international trade in achieving inclusive growth. Likewise, countries with high level of corruption will experience limited growth. In order to examine the causality, this study considers the impact of international trade and corruption on the economic growth of selected sub-Saharan African countries (Angola, Ghana, Kenya, Nigeria, and South Africa) from the period 2000-2019. The granger causality test and fixed effect method of estimation were adopted. The result of the granger causality tests shows that there is no causality between import and economic growth, there is unidirectional causality between export and economic growth and there is no causality between control of corruption and economic growth. Furthermore, it was discovered that export, import, and control of corruption have a positive impact, 25.4%, 32%, 45.5% respectively, on the economic growth of selected sub-Saharan African countries. Hence from these findings, policies towards export promotion should be encouraged as export is crucial for the economic growth of these countries and policies to curb corruption should be implemented in order to promote economic growth in the selected sub-Saharan African countries.

The purpose of this article is to present the results of surveys and attitudes of farmers and students as representatives of Polish society to the problems of Sub-Saharan Africa. Special emphasis was put on the opinions of the EU’s closure to the import of food products from African countries, which affects the socioeconomic development of Sub-Saharan Africa.

Celem artykułu jest zaprezentowanie wyników badań opinii i postaw rolników oraz studentów jako reprezentantów społeczeństwa polskiego wobec problemów Afryki Subsaharyjskiej. Szczególnie skupiono się na opiniach wobec zamykania się UE na import produktów rolno-spożywczych z krajów afrykańskich, co wpływa na rozwój społeczno-gospodarczy tych regionów.
