The role of renewable energy and agriculture in reducing CO2 emissions: evidence for North Africa countries

Abstract: This paper uses panel cointegration techniques and Granger causality tests to investigate the dynamic causal links between per capita renewable energy consumption, agricultural value added (AVA), carbon dioxide (CO2) emissions, and real gross domestic product (GDP) for a panel of five North Africa countries spanning the period 1980-2011. In the short-run, the Granger causality tests show the existence of a bidirectional causality between CO2 emissions and agriculture, a unidirectional causality running from agriculture to GDP, a unidirectional causality running from GDP to renewable energy consumption, and a unidirectional causality running from renewable energy consumption to agriculture. In the long-run, there is bidirectional causality between agriculture and CO2 emissions, a unidirectional causality running from renewable energy to both agriculture and emissions, and a unidirectional causality running from output to both agriculture and emissions. Long-run parameter estimates show that an increase in GDP and in renewable energy consumption increase CO2 emissions, whereas an increase in agricultural value added reduces CO2 emissions. As policy recommendation, North African authorities should encourage renewable energy consumption, and especially clean renewable energy such as solar or wind, as this improves agricultural production and help to combat global warming.

The dynamic linkage between renewable energy, tourism, CO2 emissions, economic growth, foreign direct investment, and trade

Abstract: Because of the lack of econometric studies in relevance to the link between tourism and renewable energy, the goal of this study is to remedy this lack and to explore the causal relationships between renewable energy consumption, the number of tourist arrivals, the trade openness ratio, economic growth, foreign direct investment (FDI), and carbon dioxide (CO2) emissions for a panel of 22 Central and South American countries, spanning the period 1995–2010. The empirical findings document that the variables under investigation are cointegrated. Short-run Granger causality tests illustrate unidirectional causalities running from: (i) renewable energy to CO2 emissions and trade; (ii) tourism to trade and FDI; and (iii) economic growth to renewable energy and tourism. In the long run, there is evidence of bidirectional causality between renewable energy, tourism, FDI, trade, and emissions. Thus, renewable energy and tourism are in a strong long-run causal relationship. Moreover, long-run estimates for the whole panel and for the three income panel groups considered (Lower Middle, Upper Middle, High) highlight that tourism, renewable energy, and FDI contribute to the reduction of emissions, while trade and economic growth lead to higher carbon emissions. Therefore, attracting foreign direct investment, encouraging the use of renewable energy, and tourism development, particularly green tourism, are good policies for this region to combat climate change.

Trade liberalization, FDI inflows, environmental quality and economic growth: A comparative analysis between Tunisia and Morocco

Abstract: The aim of this research is to investigate the possible economic impacts of the trade liberalization on the environmental quality in Tunisia and Morocco. Specifically, the paper inspects whether or not liberalization of the trade sector has harmed the quality of the environment in both countries. To this end, we conduct various econometric models: a VECM and cointegration techniques for single country case study and a Panel VECM and Panel cointegration when using data of both countries as a group. We also include a dummy variable in each model to see the real impact of trade liberalization for both countries. In the empirical section, we found bidirectional causality between FDI and CO2. This implies that the nature of FDI inflows to Morocco and Tunisia are not clean FDI. These results show that trade liberalization has a negative impact on the environment. The paper concludes that although trade liberalization boosted the economies of both countries by creating new employment opportunities, liberalization has harmed the environment.
