The causal relationship between agricultural production, economic growth, and energy consumption in Ghana

Relevance. Transition to a low-carbon economy in order to effectively and efficiently exploit the natural resource base of a country is a daunting task, especially for developing countries due to their over-reliance on climate factors. This study focuses on the case of Ghana and assesses the impact of several indicators – agricultural production, economic growth and energy consumption – on the environment. Research objectives. The aim of the study is to describe the causal relationship between agriculture production, economic growth, energy consumption and environmental degradation. Data and Methods. Using time-series data from 1975 to 2014, the study employed the ARDL model to achieve its objectives. Results. The empirical results from the bounds test provide evidence of a long-run association when the covariates are regressed on environmental degradation. The significance of the error correction term at 1% level of significance confirms this assertion. The result further shows that there is evidence of a unidirectional short-run Granger causality and a bidirectional Granger causality among the variables. There was, however, no evidence of Granger causality between economic growth, livestock production index, crop production index and environmental degradation. Conclusion. It is recommended that policy makers should prioritize the adoption of environmentally friendly technologies both in the crop and livestock sub-sectors to ensure that while the food needs of citizens are met, environmental quality is not compromised. Moreover, it is important to ensure energy use efficiency in production.

Studies of Energy Use Efficiency on Fruit Production

Studies related to energy use efficiency in Turkey and the World is one of the most important indicators for determining energy efficiency in agricultural production. In this study, previous studies related to the energy use efficiency of agricultural production in fruit areas in Turkey and the world have been included. Studies related to fruit production have been assorted and then the calculations of the indicators of energy input, energy output, energy use efficiency, energy productivity, specific energy and net energy, used to determine energy use efficiency in production areas, have been placed into tables. According to the study results, among energy inputs in fruit production chemical fertilizer consumption and fuel consumption are the most commonly used inputs. Summarized and tabulated as such, these indicators will serve as a collective resource for comparison and assessment purposes during studies to be conducted on energy use efficiency in fruit production.

India’s energy needs and low carbon options

India’s aspiration for economic growth has consequences for energy growth and CO 2 emissions. This paper examines India’s need for energy with 20 year perspectives. From an earlier paper by K. Parikh et al. (2009), demand scenario are examined from the supply perspectives ranging from coal, hydrocarbon, nuclear, hydrogen, hydro and other renewable etc. None of these are substantial and India will have to rely on imports. The need for energy has to be reduced by a drive for energy efficiency and renewable energy. Government programmes for the above are also commented upon. Though India’s CO 2 emissions are unlikely to grow very much due to energy scarcity and energy mix the article examines the potential to reduce CO 2 emissions and the associated costs involved in various options. It finds that 30% reduction in CO 2 emissions by 2030 is feasible but would involve additional costs. The most promising option is to reduce energy demand by various measures to increase energy use efficiency in production and consumption.
