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.

The paper aims to examine fall armyworm's (FAW) effect on Ghana's farming households' income and food security status.

A sample of 225 farmers, including FAW-infested households and non-FAW-infested households, were interviewed. Gross margin (GM) analysis was used to estimate farmers' farm revenues, and the Household Food Insecurity Access Scores (HFIAS) was employed to measure the food security status of the households. The seemingly unrelated regression (SUR) was adopted to investigate the effect of FAW infestation on gross income and food security.

From the study, FAW attack is predominant during the vegetative stage of the maize plant. The empirical results revealed that FAW-infested farms incur loss, whereas non-FAW-infested farmers gained profit. Also, FAW-infested households were mildly food insecure, while non-FAW-infested households were food secured. The results of SUR analysis reveal that FAW infestation decreased farmers' income from maize production and rendered them food insecure.

One limitation of this study is that it largely depended on a survey; however, future studies can combine both survey and experimental data from the farmers' fields during minor and major growing seasons of maize.

Given the negative consequences of FAW, studies have been conducted across Africa and globally. However, most of these studies concentrated on using geographic information system (GIS) and descriptive statistics without necessarily quantifying the effect of FAW on food security and the profit margins of farming households. Therefore, this study adds to the little literature on the effect of FAW on food security and GM from maize production, which has received less attention in Ghana to the authors' best knowledge.
