The rise in public debt and the increased extraction of natural resources in Ghana at a time that environmental degradation is escalating, especially with carbon dioxide emission, is worrying. This seems to cast doubt on the country's ability to meet the goals of the Paris agreement for climate change and ensuring sustainable development. Consequently, in this study, the effect of natural resources extraction and government debt on carbon dioxide emission is investigated.

The Environmental Kuznets Curve (EKC) hypothesis was adopted for this study. The Fully Modified Ordinary Least Square Model was used for assessing the data. An annual data from 1971 to 2018 was used for the analysis.

The long-run results based on the Fully Modified Ordinary Least Square analysis reveal that natural resources extraction increases carbon dioxide emissions. Moreover, the joint effect of post-oil production in commercial quantities and natural resources rent increases carbon dioxide emission. Further, the findings document that the initial stage of government debt improves environmental quality up to a point, beyond which an increase in debt hurts the environment. On the environmental degrading effect of economic growth, the findings validate the Environmental Kuznets Curve hypothesis. It is also observed that urbanization degrades environmental quality.

The study offers appropriate recommendations policymakers need to embrace towards the attainment of lower carbon emissions from the loans and natural resources rent to achieve environmental sustainability.

The effect of debt on carbon dioxide emission is assessed for the Ghanaian economy. It also contributes to studies on the natural resources-carbon emission nexus.

Quality environment is argued to be essential for ensuring food security. The effect of environmental degradation on agriculture has thus gained the attention of researchers. However, the analyses of aggregate and sectoral effect of carbon dioxide emissions on agricultural development are limited in the literature. Consequently, this study examines the effect of aggregate and sectoral carbon emissions on Ghana's agricultural development.

Time-series data from 1971 to 2017 are employed for the study. Regression analysis and a variance decomposition analysis are employed in the study.

The results show that the country's agricultural development is negatively affected by aggregate carbon emission while financial development, labour and capital increases agricultural development. Further, industrial development and emissions from transport sector, industrial sector and other sectors adversely affect Ghana's agriculture development. The contribution of carbon emission together with other explanatory variables to the changes in agricultural development generally increases over the period.

This study analyses the aggregate and sectoral carbon dioxide emission effect on Ghana's agricultural development.

Even though many studies have attempted to understand the drivers of carbon dioxide emission and energy consumption to help tackle environmental issues, not much has been done to estimate the effect of natural resources extraction on these two variables. This paper aims to analyze the long-run and short-run carbon dioxide emission and energy consumption effect of natural resources extraction in Ghana.

The theoretical foundation for this study is the Stochastic Impacts Regression on Population, Affluence and Technology (STIRPAT) model. Secondary Data sourced from World Development Indicators (2018) for the period of 1971-2013 were used. Estimation was done by using the autoregressive distributed lag.

It was found among other things that urbanization, and extraction of natural resources contribute to Ghana’s carbon dioxide emission, while official development assistance helps in reducing carbon dioxide emission in the long run. Again, while income and extraction of natural resources increase energy consumption, urbanization and official development assistance reduce environmental degradation in the long run. Regarding the short run, income and urbanization both increase energy consumption and carbon dioxide emission; trade openness and official development assistance decrease both carbon dioxide emission and energy consumption.

The implications from the results include the need to strictly enforce laws regulating extractive activities in the country to ensure a safe environment; and also to raise tariff and non-tariff barriers on products that do not promote a friendly environment and vice versa.

The effect of natural resources extraction on carbon emission and energy consumption is examined.

Ghana's economy is largely agrarian, and the business of agriculture is dominated by smallholder farmers who are predominantly rural dwellers. As a result, efforts to lift rural farming households from poverty have been narrowed to the promotion of agricultural development to the neglect of the rural non-farm sector. However, this is fast changing in the advent of a burgeoning rural nonfarm economy and must engage the attention of policy actors. This study thus assesses the effect of non-farm participation on households' level of commercialization of agricultural crops in Ghana.

The study applies a generalized structural equation model (GSEM) to the Ghana Living Standards Survey round 6 dataset, a stratified and nationally representative random sample of 16,772 households in 1,200 enumeration areas.

This study finds that non-farm participation increases the produce sold to output ratio. It is concluded that non-farm engagement by farmers boosts commercialization in Ghana. Thus, for the Ghanaian and similar contexts, agricultural development interventions that incorporate non-farm activities are more likely to be successful in improving livelihoods.

The study uses only the ratio of sales value to output value definition for commercialization and acknowledges use of multiple definitions could be superior.

Various empirical studies have examined the link between the farm and nonfarm sectors. This paper is original in its approach as it tackles an aspect of the subject that has been understudied, namely, an exploration of nonfarm and farm linkages from the perspective of agricultural commercialization.

The purpose of this paper is to examine the factors that encourage households’ source separation behaviour in Accra and Tamale Metropolises in Ghana.

Using a cross-sectional design, 855 households of Ghana were interviewed based on the theoretical framework of the theory of planned behaviour (TPB). The ordered probit regression model was employed to examine the factors that influence households’ source separation intention.

The results indicated that educational attainment of head of household, total income of household, occupation type of household head, information, past experience with source separation, inconvenience in terms of time, space and availability of formal source separation scheme, attitude, subjective norm and the location of the respondents significantly predicted households’ solid waste separation intentions.

The cross-sectional design does not determine causality but an association. Thus, future studies should examine actual household waste separation behaviour by using the experimental design to test the TPB model.

To promote solid waste separation at source, the public should be educated and provided with solid waste separation schemes that are efficient and compatible with households’ preference.

This study was partly motivated by the fact that despite the benefits associated with source separation, little attention has been given to formal source separation in Ghana. Moreover, there are limited studies on source separation behaviour in Ghana using the TPB as the theoretical framework.
