In a world increasingly subject to climate change, protected areas are of particular importance for conserving biodiversity and human livelihoods. Therefore, they play an important role in helping many species, populations, and countries adapt to climate change. This paper analyzes the effects of economic growth on the evolution of the protected areas. The study examines this relation using a sample of nine countries of the Congo Basin from 1990 to 2010. The econometric results show that an increase in the Gross Domestic Product (GDP) per capita has a positive impact on the extent of the protected area in this region regardless of the model chosen. Therefore, economic growth is a means used for the preservation of biodiversity in the Congo Basin. Moreover, the population density is negative and statistically significant. This shows that the protected areas of the Congo Basin are particularly threatened in densely populated areas.

The design, implementation, and evaluation of energy policies in combating climate change are becoming increasingly evident to strengthen economic growth driven by the agricultural sector in most developing countries. The study analyzes the direct and indirect effects of renewable energy consumption (REC) on agriculture value-added (AgVA), CO2 emissions, and trade openness in the short- and long-run in the West African countries. The second-generation panel unit root tests, the panel cointegration methods, and Panel Vector Error Correction Model are used with World Bank data from 1990 to 2015. A panel Granger causality test was also used to determine the direction of causality between variables. Findings show a unidirectional relationship between AgVA, CO2 emissions, and REC; between REC, gross fixe capital formation (GFCF) and trade openness. Moreover, the bidirectional hypothesis is verified between agricultural development and trade openness. However, the null hypothesis is found between AgVA and GFCF, on the one hand, and GFCF and CO2 emissions, on the other hand. These results suggest that fostering renewable energy policy and revisiting trade policy toward reducing environmental pollution will enable agricultural development and boost the regional economy.

An increase in electricity production is proportional to environmental risks due to continuous energy production. The paper aims to quantitatively estimate the environmental costs and mathematically model the marginal social cost associated with the lifespan of the coal power plants. Results revealed South Africa Tier 1 company optimum level of electricity production per annum at around 2.15 gigawatts, considering the emission costs and reasonable profit. 85% of the total emissions during the combustion phase average cost of the C02 emission discharged by coal is calculated as 0.23c/KWh, 0.085c/kWh is calculated for NO2, while SO2 is 0.035c/KWh. Total emission cost represents 69.2% of the total cost of producing 1 MGW of electricity. The results confirmed the company losses to be insignificantly considerable to the evaluated environmental costs and capital investment. However, the use of this newly developed mathematical model depends on the source of energy production to confirm the feasibility and profitability of investment in coal-powered stations using environmental management accounting and marginal social cost approaches. AcknowledgmentThe authors would like to acknowledge the National Research Foundation and Durban University of Technology for financial support.

Permanent access to energy is an essential pillar of economic development. However, there is a growing evidence that contemporary energy systems are not able to provide energy to the entire population on a sustainable basis and at affordable prices. In the face of these challenges, renewable energy can play an important role, especially in rural areas where access to centralized electricity grids is difficult. This paper aims to examine the access gaps of enterprises to renewable energy between rural and urban areas in Cameroon. The analysis is based on a sample of 209,482 enterprises, taken from the Second General Census of Enterprises in Cameroon (RGE-2) carried out by the National Institute of Statistics (NIS). The econometric estimations, obtained using the Blinder-Oaxaca decomposition, reveal that access rate to renewable energy for firms in rural areas is lower than that of firms located in urban areas. An increase in the level of education of the promoter of an enterprise, obtaining credit from banks, microfinance and savings, and the formalization of enterprises in rural areas can also contribute to reducing the gap in rural areas in terms of accessing to renewable energy. The discrimination suffered by rural enterprises related to the gender of entrepreneurs, the sector of activity, the business environment and professional experience tend to increase this gap. To reduce this gap, there is a need to promote access to finance for rural enterprises and their migration from the informal to the formal sector.

This study aims to analyze the direct and indirect impact of future climate changes on agricultural production and macroeconomic aggregates. A dynamic general equilibrium model of the Tunisian economy has been developed, which takes into account the effects of future climate shocks from 2020 to 2050 to assess the impact of future climate change on agricultural production and macroeconomic aggregates. The model is used to simulate various scenarios. The results of the climate shock simulations clearly show that long-term citrus fruits production is showing remarkable declines in the most citrus-producing governorates following a significant drop in water level in dams and level of groundwater table. In turn, cereals are the plants most affected by the long-term reduction in rainfall. As for the olive production, it would show a decline reaching –1.263% between 2020 and 2024 in the level of its production following reduction in rainfall. From a macro-economic point of view, climate change will result in the short- and long-term in a deterioration of certain quantities, notably household consumption, entrepreneurial investment, and the unemployment rate, which decreases by –0.139% between 2031 and 2040. These results underline the need for a long-term agricultural policy to reduce or limit the economic and social consequences of climate change and support economic development.

This study explores the symmetric and asymmetric impact of real GDP per capita, FDI inflow, and crude oil price on CO2 emission in Tunisia for the 1972–2016 period. Using the cointegration tests, namely ARDL and NARDL bound test, the results show that the variables are associated in a long run relationship. Long run estimates from both approach confirms the validity of ECK hypothesis for Tunisia. Symmetric analysis reveals that economic growth and the price of crude oil adversely affect the environment, in contrast to FDI inflows that reduce CO2 emissions in the long run. Whereas the asymmetric analysis show that increase in crude oil price harm the environment and decrease in crude oil price have positive repercussions on the environment. The causality analysis suggests that a bilateral link exists between economic growth and carbon emissions and a one-way causality ranges from FDI inflows and crude oil prices to carbon emissions. Thus, some policy recommendations have been formulated to help Tunisia reduce carbon emissions and support economic development.

This paper analyzes the revenue-pollution relationship by revisiting the Environmental Kuznets Curve (EKC) hypothesis for West African countries over the period of 1980–2014. The study approximates the income measurement by GDP per capita and uses carbon dioxide (CO2), nitrogen oxide (NO2), and methane emissions as various environmental quality measures. The paper uses parametric and non-parametric estimation techniques to test the EKC hypothesis. The results support the existence of the U-inverted relationship between income and methane emission, on one hand, and between income and nitrogen dioxide emission on the other. The estimates also show a mixed result for the U-inverted hypothesis between income and carbon dioxide emissions. Thus, the verification of the curve depends on the estimation techniques and the measurement of the pollutant used. The obtained results led to the conclusion that the EKC hypothesis is validated for West African countries.

This paper contributes to the understanding of how the environment, ethics, values, and historical contingencies shape public policy. It explains the accomplishment of petroleum resource management in the small open economy of Norway. The study is conducted by mapping policy decisions and the arguments behind them regarding environmental and ethical issues. This is done by studying available governmental and parliamentary papers along with statements from politicians and central governmental officials. The paper also seeks to illuminate some of the decisions by quantitative measures. The paper firstly describes a model of Ricardian resource rent. Secondly, it investigates the set of values that were in place before the petroleum production started in the 1970s, as described in public documents. An important argument was to build a “qualitatively better society” for the benefit of the people. Thirdly, it traces the historical roots of these values by examining historical sources.The main findings are that success lies in understanding the ethics behind the environmental resource rent harvesting of this non-renewable natural resource. The paper concludes that the focus on the natural environment and resource rent management can be attributed to popular values built on historical traditions. According to them, the state and the trust between the state and its citizens played key roles in shaping the policy. The careful policy can be illustrated by the fact that Norway has managed to build one of the largest sovereign funds in the world worth USD 1,200 billion for use by future generations. Only 3% of its value, significantly less than its historical net profit, should be used annually.

This study investigates the relationship between economic growth, final consumption, investment, energy use and CO² emissions in two groups of Middle East and North Africa (MENA) countries: Oil Poor Countries (OPC) and Oil Rich Countries (ORC). It is assumed and verified that the structural relationship between GDP growth, energy use and CO² emissions is different in these two groups of countries. FGLS panel estimations were carried out over the period 1974–2014. In ORC, no significant relationships are observed between energy use and GDP, whereas CO² emissions and GDP are positively linked. In OPC, there are opposite connections: a positive link between GDP and energy use, whereas the impact of CO² emissions on GDP tends to be negative. In both groups of countries, a positive and bi-directional link is observed between energy use and CO² emissions. The strength of this link is twice bigger in OPC than in ORC. This indicates that CO2 reduction policies conducted through energy use control (quantitative and qualitative) will have higher effect in OPC than in ORC. This also shows that the relationships between economic growth, energy use and CO² emissions differ noticeably and structurally between OPC and ORC. These results provide new insights into the opportunities and threats faced by CO2 reduction policies in OPCs and ORCs.

Despite progress in reducing air pollutants in several countries, freight transport continues to have undesirable effects on environmental quality, human health, and the economy. Road freight transport, in particular, is associated with various negative externalities, including environmental and health damages, and the overexploitation of non-renewable natural resources. This paper investigates how ICTs interact with road freight transport to affect environmental quality regarding reducing CO2 emissions. The empirical strategy is focused on the yearly dataset from 2002 to 2014 in 43 countries. Using the two-step GMM techniques, the findings suggest that ICTs can decrease road freight transport’s negative impacts on environmental sustainability. Besides, the interactions of mobile phone and fixed telephone technologies with road freight transport are more efficient in reducing pollution than using internet networks. This paper underlines the importance of using ICTs to dampen road freight transport’s negative effects on environmental sustainability.
