Land use change can have negative or positive effects on soil quality. Our objective was to assess the effects of land uses changes on the dynamics of selected soil physical and chemical properties. Soil samples were collected from three adjacent land uses, namely forestland, grazing land and cultivated land at 0–15 cm depth, and tested in National Soil Testing Center, Ministry of Agriculture of Ethiopia.

A study was taken up to identify annual changes in temperature. For this study, daily (maximum and minimum) temperature data for 45 years (1969–2013) prepared by the India Meteorological Department, Pune were used. The identification of change was based on statistical trend analysis. From the analysis, it can be concluded that the dominant tendency over the India land mass is of warming, and colder months of the year show more warming.

Despite heated debates over the safety of genetically modified (GM) food, GM crops have been expanding rapidly. Much research has focused on the expansion of GM crops. However, the spatiotemporal dynamics of non-genetically modified (non-GM) crops are not clear, although they may have significant environmental and agronomic impacts and important policy implications. To understand the dynamics of non-GM crops and to inform the debates among relevant stakeholders, we conducted spatiotemporal analyses of China’s major non-GM soybean production region, the Heilongjiang Province.
