Opis:
The paper undertakes an assessment of the economics of environmental pollution on cassava-based farmers’ health and production efficiency within the Lafarge cement concession area in Mfamosing, Akamkpa Local Government Area, Cross River State. Data for the study were sourced from 60 cassava-based farmers drawn from neighbourhood and non-neighbourhood locations and analyzed using descriptive statistics and stochastic production frontier techniques. The result showed that farming activities in the area have been dominated by females with an average age of 43 and 35 years of age and household size between 4 and 6 persons. Clearly, the results indicate that cement plant activities have reduced farm productivity over the last 5 years, and has affected the livelihood of the farmers. The study also averred that respiratory diseases, diarrhea, skin rashes, heart disease, asthma, coughs and skin cancer have been the various health challenges suffered by the farmers. According to the study results, farmers lost 44 days due to heart disease, 33 days due to respiratory diseases, and 7 days due to diarrhea. The result of the maximum likelihood estimates (MLEs) of the stochastic frontier production function indicate that hired labour, quantity of fertilizer used and quantity of cassava stem cuttings were the significant variables that influenced cassava yield. The estimated technical efficiency (TE) ranged from 0.45 - 0.99, with a mean index of 0.67 (target group) and 0.57 – 0.99, with a mean of 0.82 (control group). The number of days lost due to illness was the most significant variable influencing inefficiency levels in the study area. It was, therefore, recommended that policies aimed at increasing efficiency should focus on improving health care services in the farming communities, while encouraging efficient level of pollution control by the prescribed cement factory, ab initio.

Opis:
The study examined the impact of climate variability on yield of maize and yam in Cross River State, Nigeria. The specific objectives of the study were to determine the long-run and short-run impact of climate variability factors on yields of maize and yam. Data were sourced from the Nigerian Meteorological Agency (NiMeT) and Cross River State Ministry of Agriculture spanning from 1990-2016. Data obtained were analyzed using inferential statistics. Precisely, the model was estimated by the Ordinary Least Squares (OLS) multiple regression technique, which is within the Autoregressive Distributed Lag Bound approach and error correction testing framework. Both model-1 (maize yield) and model-2 (yam yield) passed through the conditions of the diagnostics and stability test. The study revealed that climate variables had a significant impact on maize yield both in the long and short-run. Based on the findings, it was concluded that proactive measures should be put in place to aid crop farmers adapt to the prevailing and looming threats of climate variability for the purpose of attaining the State’s food security balance sheet. To sustain this drive, an institutional and infrastructural support system is advocated in order to meet one of the goals of sustainable development agenda of the United Nations. Policy recommendations on how to cushion the impact of climate variability on the prescribed crops have been appropriately cited.
