“…Large cities in Sub-Saharan Africa, like KCP, Capital of Democratic Republic of Congo (DRC), are facing a dramatic population explosion (Khennas 2012;Hanif 2018;Mambanzulua et al 2015a). This is the result of the increasing of rural-urban migration and the displacement of people from areas of armed con icts such as the Eastern part of the DRC.…”

“…This is the result of the increasing of rural-urban migration and the displacement of people from areas of armed con icts such as the Eastern part of the DRC. Those displacements cause anarchic subdivisions in the peri-urban green spaces and increase crops and energy consumption in KCP (Hanif 2018;Mambanzulua et al 2015a, b). Therefore, in KCP there is an increase in the production of improperly managed wastes, deforestation and decreasing areas of arable lands which are otherwise infertile (Hanif 2018;Mambanzulua et al 2015aMambanzulua et al , 2015b; Barrios et al 2006).…”

“…This energy is renewable and its net CO 2 contribution to the atmosphere is nil. Moreover, it could keep KCP away from deforestation by providing its households with a form of clean energy for cooking; given nearly 80% of the population of KCP rely on ligneous biomass (mainly charcoal) to satisfy their energy needs (Khennas 2012;Hanif 2018;Mambanzulua et al 2015a, b). The biogas obtained by biomethanation of these wastes, is a second generation biofuel.…”

“…The biogas obtained by biomethanation of these wastes, is a second generation biofuel. The latter is more advantageous than the rst or third generation biofuels (Hanif 2018;Mambanzulua et al 2015b;Chandra et al 2012). As an advantageous energy source, biogas is widely considered as a suitable fuel for heating facilities, power generation, and vehicles (Li et al 2017;Galvagno et al 2007;Shan et al 2016).…”

Optimal scale production of biogas from the anaerobic digestion (AD) of organic wastes (OWs) as substrates has become one of stimulating environment-friendly procedures to foster the replacement of fossil energies by renewable ones. AD of OWs generated from households is desirable as an effective method to fight against environmental pollution effects of the latter in developing countries. Notably in Africa where each year there are more than 600,000 premature deaths following the use of solid biomass energy (especially charcoal). Yet, if assessing the potential of biogas production, that is, biochemical methane potential (BMP) has played a prominent role in the choice of substrates, in the other hand the evaluation of the optimal ratio between the quantity of variety OWs and the amount of energy to be produced has not received several attentions. The latter is valuable not only for energetic productivity but also for profitability. Thus, in this report, an energetic balance between the amount of leaves and stems of Manihot Utilissima (MU) annually produced as well as the energetic potential of their biogas were investigated. Cow manure (CM) was employed as inoculum, under mesophilic conditions of the collection sites: Ngaba and Ndjili in Kinshasa City Province (KCP), Congo DR, where the leaves and stems of MU are among the most generated wastes. Furthermore, we evaluated the fertilizing potential of digestates from the AD of the leaves and stems by their Carbon/Nitrogen (C/N) ratios. The annual energetic potentials of biogas produced were estimated to be 1.362 ± 0.028 109 kWh for the leaves and 0.337 ± 0.006 109 kWh for the stems. These were associated to the energy needs for the KCP households corresponding to the use of charcoal. The latter was evaluated to be 166 103 tons for leaves and 41 103 tons for the stems of MU, respectively. The fertilizing potential of digestates from the AD of the leaves and stems of MU assessed by their C/N ratios were determined to be 5 and 10, respectively; indicating that they are favorable for the cultivation of vegetables and fruit trees in KCP soils (C/N ~ 5) but also optimal for the organisms, soil conditioning and could improve the soils hydraulic conductivity (C/N ~ 10).

The study examines the impact of economic growth, energy use and population growth on carbon emissions in sub Saharan Africa: Kenya, Nigeria, Botswana, Benin, Togo and Mauritius for the period of 1990-2014. The study employed unit root test, co-integration test, VECM (Vector Error Correction Model) and FMOLS (Fully Modified Ordinary Least-Square) as methodologies to model the causality and linear relationships amongst the variables. The VECM was used to identify the long-run causality and asymptotic convergence among the variables. The results reveal that an increase in energy use and population growth by 1% would cause an increase in CO 2 (Carbon Dioxide) concentration by 0.08% and 0.22% correspondingly, whereas in the long-run 1% increase of energy use increases economic output by 0.09%. As the economy grows without contributing to carbon emissions, governments should invest more in renewable energy. Governments should also come up with policies to regulate population growth and fossil energy use.

The pathway toward pollution mitigation: Does institutional quality make a difference?

Institutions in a country ensure sustainability and play a significant role in economic development by encouraging best practices in governmental interventions. A strong and transparent institutional framework opposes corruption and improves the management of public finances, which may also yield desired outcomes for the environment and society. However, the role of institutions in environmental issues is still under-investigated in the literature. This study aims to investigate the relationship between renewable energy consumption, institutional quality, economic performance, and carbon dioxide (CO 2) emissions in 18 Asia-Pacific Economic Cooperation (APEC) countries for the period 1992-2015. To this end, robust panel data estimation techniques are employed. The study confirms that a cointegration relationship exists among study variables. Evidence from the empirical results reveals that institutions have beneficial environmental effects. Likewise, renewable energy reduces carbon emissions to mitigate climate change, but nonrenewable energy harms the environment. Institutional quality helps to form the environmental Kuznets curve hypothesis in APEC countries. Finally, causality analysis refers to the unidirectional causality running from institutional quality to CO 2 emissions. Results reveal that stronger institutional arrangements in APEC countries could be the solution for implementations of effective environmental regulation to combat rising environmental challenges without sacrificing higher economic growth.
