“…The reduction in teff, maize and wheat can endanger food security because these are the main consumption commodities in major crop-producing areas of the country. This is also supported by Valin et al (2013) and Ekpenyong and Ogbuagu (2015). It also implies that the CO 2 emission problem remains a challenge to Ethiopia, as the major agricultural activities respond in the reverse direction even under the CRGE scenario, but by far it is better in comparison with the other scenario.…”

“…These results suggest that energy consumption can induce economic growth but not vice versa in Chile. Valin et al (2013) also examines the reverse effects of climate change on agricultural productivity using partial econometric analysis and also finds that closing yield gaps by 50% for crops and 25% for livestock by 2050 would decrease agriculture Ekpenyong and Ogbuagu (2015) also indicate the existence of a negative relationship between agricultural productivity and climate change and 100% increase in greenhouse emission will lead to 22.26% decline in AGP. Vasco et al (2019) evaluate the effect of CO 2 on the growth performance, welfare and health of Atlantic salmon post-smolts and regressions showed that growth significantly decreased linearly with increasing CO 2 .…”

Purpose Climate change has become one of the most important development challenges worldwide. It affects various sectors, with agriculture the most vulnerable. In Ethiopia, climate change impacts are exacerbated due to the economy’s heavy dependence on agriculture. The Ethiopian Government has started to implement its climate-resilient green economy (CRGE) strategy and reduce CO2 emissions. Therefore, the purpose of this study is to examine the impact of CO2 emission on agricultural productivity and household welfare. Design/methodology/approach This study aims to fill these significant research and knowledge gaps using a recursive dynamic computable general equilibrium model to investigate CO2 emissions’ impact on agricultural performance and household welfare. Findings The results indicate that CO2 emissions negatively affect agricultural productivity and household welfare. Compared to the baseline, real agricultural gross domestic product is projected to be 4.5% lower in the 2020s under a no-CRGE scenario. Specifically, CO2 emissions lead to a decrease in the production of traded and non-traded crops, but not livestock. Emissions also worsen the welfare of all segments of households, where the most vulnerable groups are the rural-poor households. Originality/value The debate in the area is not derived from a rigorous analysis and holistic economy-wide approach. Therefore, the paper fills this gap and is original by value and examines these issues methodically.

“…Closing yield gaps for crops and livestock could reduce emissions by 8% overall and 12% per calorie produced by 2050. Ekpenyong and Ogbuagu's (2015) study reveals a negative correlation between agricultural productivity and climate change in Nigeria, with a 100% increase in greenhouse gas emissions resulting in a 22.26% decrease in AGP. And, the Edoja et al (2016) study in Nigeria also found a long-term association between CO2 and agricultural productivity, with a one-way causal connection between CO2 and food security.…”

The consequences of greenhouse gas emissions are a global problem and are felt most clearly in poor countries. Every sector in Ethiopia is affected by greenhouse gas emissions, but the productivity of the agricultural sector is particularly at risk. Although climate change is a long-term phenomenon, no in-depth macro-level studies have been conducted to guide discussion in this area. Therefore, the study fills this gap and carefully examines these impacts over time from 2019 to 2022 using the Vector Auto Regressive Model. Our results show that a 1% increase in fertilizer consumption, agricultural land, nitrous oxide (N2O) emissions, rural population, and area devoted to grain production results in a 0.28, 2.09, 15.92, 5.33, and 1.31 percent increase in agricultural yield in the long-run, respectively. A negative relationship was found between agricultural employment, agricultural methane emissions (CH4), carbon dioxide emissions (CO2), and agricultural productivity with a significance level of 5%. This means that under a black box condition, a one percent increase in agricultural employment, CH4, and CO2emissions in the country in the long run will lead to a decrease in agricultural productivity by 5.82, 17.11, and 2.75 percent respectively, as we also found that all regressors except technology adoption had an elastic relationship with agricultural productivity. The short-term error correction estimates show that the coefficient of the “speed of adjustment” term for the expected productivity equation is both statistically significant and negative. The value of the coefficient term of −0.744 shows that an adjustment of 74.4% is made each year to converge the long-run equilibrium level. Therefore, Ethiopia needs to take measures that keep the economy away from sectors that produce a lot of carbon. These must be coordinated at a global level to achieve social change towards a fair and environmentally sustainable future and to increase agricultural productivity.

“…Agriculture remains a major source of livelihood and employment for more than 50% of the labour force (Manyong et al, 2005). However, the issue of climate change has become a major concern and threat to agricultural production in Nigeria, and if not addressed can lead to food security issues (Ekpenyong & Ogbuagu, 2015). Currently, there are problems of adaptation by farmers to the changing climate leading to elimination of farming certain tropical crops and some farmers are beginning to change occupation and business (Collier et al, 2008).…”

This study explores the role of government in promoting business sustainability in agriculture in an emerging country. Goal 1 to 3 of the United Nations sustainability targets eradicating poverty and hunger which is a significant problem in emerging economies like Nigeria. 70 questionnaires were distributed to participants in order to find out about government's role in promoting sustainable agriculture and partnership with agricultural entrepreneurs to provide quality and sustainable food both for now and the future. The result shows poor orientation towards sustainability and a lack of initiatives towards climate change.
