This study analysed long-term land-use and land-cover change (LUCC) in a highland watershed covering an area of about 154 km 2 in the Blue Nile basin of Ethiopia. Two sets of panchromatic aerial photographs (1957 and 1982) and a Landsat TM image (2001) were the main input data from which three land-use and land-cover maps were produced by employing geographical information systems/remote sensing techniques. These data were complemented by some socio-economic data that were generated by using household survey, key-informant interview and group discussion methods. The results show that in regard to land-use and land-cover, the major change has been the reduction of areas under natural vegetation cover and expansion of open grassland, cultivated areas and settlements. Over the four and a half decades considered, areas of forest and dense tree cover and shrub grassland decreased by 64 and 6%, respectively. Forest and dense tree cover experienced the greatest change; from accounting for $9% of the total area of the watershed in 1957 to only $3% in 2001. In general, much of the de-vegetation occurred between 1982 and 2001. Cropland and rural settlement showed a small but consistent increase between 1957 and 2001. Riparian vegetation decreased during the first period, but increased almost to the same level during the second period by gaining land from the other land-use and land-cover types. The observed LUCCs were driven by a combination of proximate and underlying causes. These include increasing demographic pressure and associated demands on environmental resources, widespread rural poverty and inadequate management of common property resources owing to poorly defined ownership arrangements. There is a need for short-term and long-term strategies to ensure sustainable land management and agricultural development in the watershed.

Poor waste management is increasingly becoming a major challenge for municipalities, globally. Unlike previous waste management studies in Nigeria, this study examines the implications of waste management to regional greenhouse gas emissions based on awareness levels and perception of urban inhabitants. Benin City was divided into four residential zones: core, intermediate, suburban, and planned estates. Blocking was utilized to collect data from a total of 2720 randomly selected inhabitants through a self-administered survey. Results reveals low awareness level in terms of indiscrimination dumping of waste, thereby promoting sustainable mitigation and adaptation measures region-wide. It is imperative to integrate various aspects of regional government services such as infrastructure, urban planning and development, socioeconomics, public health, and regulation enforcement. Waste management policy is strengthened via working groups, community, and regional authorities.

A focalized analysis and reporting on the problems of general government debt (GGD) and government deficit (GD) and their influencing factors on economic growth rate tell the story of positive, neutral, and negative economies. Research was conducted over a nineteen-year period between 2000 and 2018 on all eleven post-communist European Union Member States (MS). MSs are divided in to three regional blocks: (1) the Baltic countries, (2) Central and Eastern European countries, and (3) the Balkan countries. Reviewed literature examined different types of GGD and GD with denoted influence on each MS’s economy and government. GGD and GD increase as a result of State intervention by reacting to economic fluctuations needed in creating redistributive-related fiscal policy. A breakdown of the problems of fiscal policy is explained. Datasets were compiled and systematically analyzed using Eurostat indicators. European regulatory benchmarking was used for GGD and GD as a percentage of gross domestic product. Results were divided at the regional group level. Comparative tax systems based on total general government revenue as well as total tax and contribution rate were evaluated. Histo-geographical research was considered and a comparative examination of GGD, GD and growth rate illustrated. In terms of GGD, GD, and growth rate, the Baltic countries were best situated, while all other countries were generally stable—with the exception of Hungary, Croatia, and Slovenia. In all, negative or stagnant periods revealed a general positive trend throughout the study with the exception of the world financial crisis of 2008, in which a deteriorative impact on growth rate was evident in all MS—especially from 2009. In the latter years, MSs’ economic promise signals a high potential for renewed public finance and stability initiatives.
