In this paper, the relationship between carbon dioxide and agriculture in Ghana was investigated by comparing a Vector Error Correction Model (VECM) and Autoregressive Distributed Lag (ARDL) Model. Ten study variables spanning from 1961 to 2012 were employed from the Food Agricultural Organization. Results from the study show that carbon dioxide emissions affect the percentage annual change of agricultural area, coarse grain production, cocoa bean production, fruit production, vegetable production, and the total livestock per hectare of the agricultural area. The vector error correction model and the autoregressive distributed lag model show evidence of a causal relationship between carbon dioxide emissions and agriculture; however, the relationship decreases periodically which may die over-time. All the endogenous variables except total primary vegetable production lead to carbon dioxide emissions, which may be due to poor agricultural practices to meet the growing food demand in Ghana. The autoregressive distributed lag bounds test shows evidence of a long-run equilibrium relationship between the percentage annual change of agricultural area, cocoa bean production, total livestock per hectare of agricultural area, total pulses production, total primary vegetable production, and carbon dioxide emissions. It is important to end hunger and ensure people have access to safe and nutritious food, especially the poor, orphans, pregnant women, and children under-5 years in order to reduce maternal and infant mortalities. Nevertheless, it is also important that the Government of Ghana institutes agricultural policies that focus on promoting a sustainable agriculture using environmental friendly agricultural practices. The study recommends an integration of climate change measures into Ghana's national strategies, policies and planning in order to strengthen the country's effort to achieving a sustainable environment.

The relationship between carbon dioxide, crop and food production index in Ghana: By estimating the long-run elasticities and variance decomposition Sarkodie, Samuel Asumadu; Owusu, Phebe Asantewaa (2017-06-01) The study estimated the relationship between carbon dioxide, crop and livestock production index in Ghana: Estimating the long-run elasticities and variance decomposition by employing a time series data spanning from 1960-2013 using both fit regression and ARDL models. There was evidence of a long-run equilibrium relationship between carbon dioxide emissions, crop production index and livestock production index. Evidence from the study shows that a 1% increase in crop production index will increase carbon d...
The causal nexus between energy use, carbon dioxide emissions, and macroeconomic variables in Ghana Asumadu-Sarkodie, Samuel; Owusu, Phebe Asantewaa (2017-01-01) The study examined the causal nexus between energy use, carbon dioxide emissions, and macroeconomic variables in Ghana with data spanning from 1960 to 2013 using the vector error correction model (VECM). It is evidential from the study that almost 12% of future fluctuations in energy use are due to shocks in financial development and 10% of future fluctuations in carbon dioxide emissions are due to shocks in energy use. There was evidence of a bidirectional causality between: energy use and financial develo...
The impact of energy, agriculture, macroeconomic and human-induced indicators on environmental pollution: evidence from Ghana Asumadu-Sarkodie, Samuel; Owusu, Phebe Asantewaa (2017-03-01) In this study, the impact of energy, agriculture, macroeconomic and human-induced indicators on environmental pollution from 1971 to 2011 is investigated using the statistically inspired modification of partial least squares (SIMPLS) regression model. There was evidence of a linear relationship between energy, agriculture, macroeconomic and humaninduced indicators and carbon dioxide emissions. Evidence from the SIMPLS regression shows that a 1% increase in crop production index will reduce carbon dioxide em...
Carbon dioxide emissions, GDP, energy use, and population growth: a multivariate and causality analysis for Ghana, 1971-2013 Asumadu-Sarkodie, Samuel; Owusu, Phebe Asantewaa (2016-07-01) In this study, the relationship between carbon dioxide emissions, GDP, energy use, and population growth in Ghana was investigated from 1971 to 2013 by comparing the vector error correction model (VECM) and the autoregressive distributed lag (ARDL). Prior to testing for Granger causality based on VECM, the study tested for unit roots, Johansen's multivariate co-integration and performed a variance decomposition analysis using Cholesky's technique. Evidence from the variance decomposition shows that 21 % of ...
Recent evidence of the relationship between carbon dioxide emissions, energy use, GDP, and population in Ghana: A linear regression approach Asumadu-Sarkodie, Samuel; Owusu, Phebe Asantewaa (2017-01-01) In this study, the relationship between carbon dioxide emissions, energy use, GDP, and population was examined in Ghana from 1971-2013 using a linear regression approach. Evidence from the study shows a long-run equilibrium relationship running from energy use (EU), gross domestic product (GDP), and population to carbon dioxide emissions. There was evidence of long-run equilibrium relationship from GDP to carbon dioxide emissions and population to carbon dioxide emissions. There was a unidirectional causali...
