“…When the average precipitation increases by 1 percent, the groundnuts' farm returns increase by 0.115 percent. In the same vein of research, Granados et al (2017) and Ater & Aye (2012) obtain similar results. On the contrary, average, precipitation has a significant negative relationship with farm returns for beans.…”

“…These empirical results are consistent with those of Tokunaga et al (2015) in Japan whose elasticities are between -0.39 percent and -0.82 percent. Etwire et al (2019) in Ghana find that for 1 percent increase in average temperature, the plantains revenues decrease by 2.612 percent, in Nigeria, Ater & Aye (2012) empirically estimate elasticity as -2.589 percent. Exenberger et al (2014) find different elasticities for grouped countries, for example -0.004 percent for high income, -0.014 percent for middle income and -0.016 percent for low income.…”

The study examined the effect of climate change on agricultural crop returns in Uganda using the Ricardian Panel Tobit technique and the World Bank Living Standards Measurement Survey (LSMS) data, climate data from Uganda National Meteorological Authority (UNMA) and global weather data. The findings showed that climate related risks account for over 67 percent of agricultural risks and less than 2 percent of the farming households practise irrigation. Farmers that practised irrigation earned higher agricultural returns nationally than their counterparts did. The findings show that the output elasticities with respect to temperature range from -2.02 percent to 0.543 percent. This implies that for the average temperature increase by 1 percent, maize farm returns decreased by 2.02 percent, banana by 1.7 percent, cassava by 1.50 percent and beans by 1.01 percent. While 1 percent increases in rainfall, lowered banana returns by 0.02 percent, beans by 0.08 percent, cassava by 0.035 percent, maize by 0.025 percent except for groundnuts’ returns increased by 0.115 percent. Apart from climate factors, non-climate factors such as capital, labour, farm size, fertilizers and soil quality are equally important inputs and significantly impact on agricultural farm returns. The study proposes that due to unrelenting adverse climate change effects in Uganda, adoption of multi-pronged approaches such as extensive irrigation, agro-insurance, diversification of agricultural activities, use of food cribs during bumper harvests would be the breath of life for Ugandan farmers.

“…Moreover, impacts of climate change will vary according to location, soil type, crop, and other local factors. Consequently, it is essential to conduct enterprise-specific analysis (Ater and Aye 2012;Sarker et al 2012). In a review by Knox et al (2012), it was indicated that for yams, there were too few studies to comment on if there has been any significant impact of climate change on the yield in West Africa.…”

Examining Yam Production in Response to Climate Change in Nigeria: A Co-Integration Model Approach

2020

This study addressed yam production in response to climate change in Cross River State using a co-integration model approach. The specific objectives of this paper are to analyze the trend in yam production, annual precipitation, and annual temperature, and to analyze the impact of climate variables on yam production. Time-series data from 1996 to 2017 was used. Based on the analysis, which constituted a linear trend analysis, co-integration test, and error correction model, the study came up with robust findings. The linear trend analysis for yam production revealed a steady increase in output between the years 2005 and 2016. The result of the rainfall trend analysis showed the presence of rainfall variability and irregularity. The trend line for temperature showed an overall downward trend for the period under study. However, the Error Correction Model result showed that temperature was statistically significant and negatively impacted yam production. The study recommends that policymakers should take appropriate steps to encourage the development of pest- and disease-tolerant yam varieties because an increase in temperature leads to the proliferation of insects, pests, and diseases.

“…A growing body of economic literature has focused on the impacts of climate change on the agriculture sector at a macro level [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. The common finding of these studies is that climatic changes adversely affect crop yields.…”

Do Farmers Adapt to Climate Change? A Macro Perspective

et al. 2020

View full text Add to dashboard Cite

Greenhouse gas emissions cause climate change, and agriculture is the most vulnerable sector. Farmers do have some capability to adapt to changing weather and climate, but this capability is contingent on many factors, including geographical and socioeconomic conditions. Assessing the actual adaptation potential in the agricultural sector is therefore an empirical issue, to which this paper contributes by presenting a study examining the impacts of climate change on cereal yields in 55 developing and developed countries, using data from 1991 to 2015. The results indicate that cereal yields are affected in all regions by changes in temperature and precipitation, with significant differences in certain macro-regions in the world. In Southern Asia and Central Africa, farmers fail to adapt to climate change. The findings suggest that the world should focus more on enhancing adaptive capacity to moderate potential damage and on coping with the consequences of climate change.
