Croissance économique et dégradation de l'environnement au Cameroun

Abstract

Résumé Ce papier a pour objectif d'examiner les effets de la croissance économique sur les émissions de dioxyde de carbone (CO2) et sur l’évolution de la température au Cameroun sur la période 1972–2010. Le test de cointégration par les retards échelonnés ou Auto Regressive Distributed Lags (ARDL) indique l'existence d'une relation de long terme sous forme de « N inversé » entre la croissance économique et les indicateurs de dégradation environnementale (émissions de CO2 et évolution de la température) retenus dans cette étude. Ensuite, on constate que la consommation d’énergie et les activités industrielles accroissent les émissions de CO2 mais pas l’évolution des températures au Cameroun. Par contre, l'ouverture commerciale entraine une baisse du niveau de CO2 mais pas de la température. Ce résultat laisse entrevoir que le Cameroun exporte ou transmet sa pollution vers l'extérieur ou vers d'autres pays.

Infrastructure, Investment, and Environmental Degradation: A Study of Economic Development in West Sumatra

“…However, only agricultural variables partially influence environmental degradation (IKLH), while trade, industrial, and economic growth variables have no effect. The results of this analysis are in line with the opinion of the researchers [47][48][49], which implies a strong relationship between agriculture and environmental degradation. However, the results of this analysis are not in line with empirical research:…”

“…The results of this analysis are also in line with the opinion of the researchers [41][42][43][44][45], which proves the relationship and influence of the trade sector on economic growth. However, the results of this analysis are not in line with the opinion of the researchers [48], proving that there is a relationship and influence of the industrial sector on economic growth.…”

“…H8: Empirical research to prove the relationship and influence of the trade sector on economic growth so that the nine research hypotheses can be identified [46]: H9: Empirical research suggests a strong relationship between agriculture and Environmental Degradation so that the ten research hypotheses can be identified [47][48][49]: H10: Previous research conducted by studies [50,51] indicated the influence of trading activities on Environmental Degradation; so that the eleventh research hypothesis can be identified: H11: Empirical research by studies [52,53] indicates the influence of industry on Environmental Degradation; so that the twelfth research hypothesis can be identified: H12: Research and empirical data imply a strong relationship between economic growth and environmental degradation so that the thirteenth research hypothesis can be identified [54][55][56]: H13: Economic growth affects environmental degradation.…”

Economic Growth and Carbon Dioxide Emissions in Côte d’Ivoire: An Empirical Analysis of the Environmental Kuznets Curve Hypothesis

“…In the early 90s, a number of scientific studies set out to test the environmental Kuznets curve hypothesis between economic growth and indicators of environmental degradation (SO2, NOX, CO2, CO, municipal waste and suspended particulates) (Grossman & Krueger, 1995;Panayotou, 1993;Shafik & Bandyopadhyay, 1992;Selden & Song, 1994). Several authors have offered a detailed review of empirical work on the relationship between economic growth and environmental quality, using per capita CO2 emissions as an indicator of environmental quality (Jalil & Mahmud, 2009;Shahbaz et al, 2014;Raheen & Ogebe, 2017;Domguia & Ndieupa, 2017). The diversity of work confirms that environmental problems differ from region to region and country to country.…”

Decoupling greenhouse gas emissions from economic growth in cameroon

“…However, we noted that previous studies used CO 2 as a proxy for decoupling economic growth and environmental pollution, and most of them had defined decoupling status only, without exact reasons.Furthermore, in Cameroon, the few studies available on the question of energy-related to environmental pollution such as those of (Tamba, 2017; Noubissi Domguia & Njangang, 2017; Hilaire & Hervé, 2012), [25][26][27] have only evaluated the causal relationships between environmental, economic, and energy factors. Based on these considerations, the objective of this study is to evaluate the decoupling relationship between economic growth and GHG emissions in Cameroon over the period 1971-2014, based on the Tapio model.The analyzes were carried out according to Cameroon's three major periods of economic development, particularly the period preceding the economic crisis (1971)(1972)(1973)(1974)(1975)(1976)(1977)(1978)(1979)(1980)(1981)(1982)(1983)(1984), the period of economic crisis (1984)(1985)(1986)(1987)(1988)(1989)(1990)(1991)(1992)(1993)(1994) and the period following the crisis (1994-2014).…”
