Rice production in Nigeria is vulnerable to climate risks and rice farmers over time have experienced the risks and their respective impacts on rice farming. Rice farmers have also responded to perceived climate risks with strategies believed to be climate-smart. Farmers’ perception of climate risks is an important first step of determining any action to be taken to counteract the negative effects of climate change on agriculture. Studies on the link between perceived climate risks and farmers’ response strategies are increasing. However, there are limited studies on the determinants of rice farmers’ perception of climate events. The paper therefore examined climate change perception and uptake of climate-smart agriculture in rice production in Ebonyi State, Nigeria using cross-sectional data from 347 rice farmers in an important rice-producing area in Nigeria. Principal component analysis, multivariate probit regression model and descriptive statistics were adopted for data analysis. Perceived climate events include increased rainfall intensity, prolonged dry seasons, frequent floods, rising temperature, severe windstorms, unpredictable rainfall pattern and distribution, late onset rain, and early cessation of rain. Farmers’ socioeconomic, farm and institutional characteristics influenced their perception of climate change. Additionally, rice farmers used a variety of climate-smart practices and technologies to respond to the perceived climate events. Such climate-smart practices include planting improved rice varieties, insurance, planting different crops, livelihood diversification, soil and water conservation techniques, adjusting planting and harvesting dates, irrigation, reliance on climate information and forecasts, planting on the nursery, appropriate application of fertilizer and efficient and effective use of pesticides. These climate-smart agricultural measures were further delineated into five broad packages using principal component analysis. These packages include crop and land management practices, climate-based services and irrigation, livelihood diversification and soil fertility management, efficient and effective use of pesticide and planting on the nursery. High fertilizer costs, lack of access to inputs, insufficient land, insufficient capital, pests and diseases, floods, scorching sun, high labour cost, insufficient climate information, and poor extension services were the barriers to uptake of climate-smart agriculture in rice production. Rice farmers should be supported to implement climate-smart agriculture in rice production in order to achieve the objectives of increased rice productivity and income, food security, climate resilience and mitigation.

This study examined the impacts of climate change on okra and tomato yields. Fertilizer consumption and credit to the crop sector were considered as covariates in the analysis. Time-series data, spanning a period of 40 years, were obtained from various sources. An autoregressive distributed lag model was applied to analyze short- and long-term impacts of climate change and agricultural inputs on okra and tomato yields. Not all variables were stationary at levels (order zero), but they were all significant at first difference, indicating the presence of cointegration. The Bound’s test F-ratio was statistically significant and implied the presence of long- and short-term relationships among the variables studied. The mean temperatures had negative impacts on okra and tomato yields in both the short and long terms. Credit guaranteed to the crop sector had positive short- and long-term impacts on tomato yield; fertilizer consumption had a negative long-term impact on okra yield. Our study concludes that climate change, particularly rising temperature, impacts herbaceous fruit crop production in Nigeria. Therefore, we recommend that breeding and disseminating climate-smart tomato and okra varieties will help fruit crop farmers respond to rising temperatures.

The study evaluated the climate change impacts and adaptation strategies of cassava farmers in Ebonyi State, Nigeria. Multi-stage sampling was used to select 419 cassava farmers who administered the questionnaire. Data were collected using primary and secondary means and were analysed using mean, frequency, percentage, beta regression model, and ordinary least squares multiple regression techniques. Factors influencing cassava production are meteorological information (95.7%), tradition and culture (94.5%), improved technology utilization (93.1%) and low access to credits (71.8%). Climate change effects on cassava production were reduced biodiversity (95.2%), increased crop failure (97.6%), decreased yield (100%) and increased soil salinity (92.6%). Cassava farmers adapted to various practices such as planting improved cassava varieties (95.9%), insurance (3.3%), planting different crops (96.9%), and livelihood diversification (94.9%). Age, education, household size, farm size and extension contacts were significant determinants of climate change adaptation strategies of cassava farmers. Variables such as temperature, rainfall, humidity and sunshine had both positive and negative impacts on cassava production. The study recommends cassava farmers seek early warning signals and information on climate change before embarking on their farming operations to avert possible negative consequences.

The present study evaluated the perceived effects of the COVID-19 Pandemic on food security in Southeast Nigeria. A multi-stage random technique was used to select 209 households. Data for the study were collected with the aid of a structured questionnaire and were analyzed using descriptive statistics, z-test, food security model, and Tobit regression model. Results showed that the mean household size was 9.6 persons, which indicates a large household size. The percentage rate of food consumption of the households before the Pandemic was higher relative to the COVID-19 event. Again, exorbitant prices of food materials were noticed during the COVID-19 as compared to the period before the Pandemic. About 10.5% of the households met the minimum food requirements as proposed by World Health Organization (WHO), and Food and Agriculture Organization (FAO) as against the majority of 76.1%. The three dimensions of food security which include availability, accessibility, and utilization were interposed by a number of factors, such as artificial scarcity, and an increase in food prices. Furthermore, social distancing and lockdown imposition were COVID-19 determinants of the food security status of households in the Southeast Nigeria. About 24% of the households were food-secured compared to 76% that were insecured during the Pandemic. Robust and effective food and agricultural policy formulations and implementations were recommended in Southeast Nigeria.

Impact of climate change and extension service on rice farmers' yield in Ebonyi State, Nigeria. Asian J Agric 8: 116-123. The study examined the impact of climate change and extension service on rice farmers' yield in Ebonyi State, Nigeria. A total of 402 rice farmers were sampled through multi-stage sampling for questionnaire administration. Primary data collected were analyzed using mean, frequency, percentage, ordinary least square multiple regression techniques, the Local Average Treatment Effect (LATE) model, and the probit model. Socio-economic characteristics show that a greater proportion of the farmers were male (51.7%), married (84.1%), and attended secondary education (47.8%). Sources of climate change information were farmer-to-farmer (100%), telephone/mobile phone (98.5%), radio (92.5%), workshop/seminars (73.4%), and television (46.8%). Temperature (P<-0.01), rainfall (P<-0.01), evaporation rate (P<-0.01), and severe windstorm (P<-0.01) influenced rice yield negatively, while relative humidity (P<0.05) and atmospheric pressure (P<0.01) had a positive influence on rice yield. The results from the LATE model, which measures the average effect of a treatment on the treated, show a decrease in rice yields of 84.1% and 96.5%. Production constraints felt by rice farmers include high cost of input materials (100%), inadequate capital (100%), high cost of labor (99.8%), poor extension access and service (99.5%), and Fulani-herdsmen conflict (76.9%). The study recommends rice farmers implement climate-smart agriculture to mitigate climate change and access farm information and/or services from experienced farmers.

Aim of the Study: The study reviewed carbon farming, carbon market, and climate justice and energy transition in reducing carbon emission in Nigeria. Methodology: The study being a qualitative review made use of literature reviews. A total of 400 papers on climate change, carbon farming, carbon market, carbon emissions, climate justice, and energy transitions were downloaded across various databases including (scopus, web of science, google scholar, and research gate). The authors peruse the 400 papers carefully to select the required ones based on the title of the research paper in focus. Papers not relating to the title of the research study were excluded numbering 372 leaving only 28 papers which focused basically on the research study of interest and concern. The included 28 scientific papers were thoroughly perused further and used for the review reports. Findings: Based on the review results, there has been a universal call for the decarbonization of the global environment. This has necessitated the need for renewable energy and other forms of sustainable energy in Nigeria such as solar, wind, geothermal, hydropower, and bioenergy. Nigeria government has taken steps in ensuring a free, cleaner and safer environment via adoption of cutting edge technologies such as carbon farming, carbon markets, climate justice, and just energy transitions with few significant successes. Nigeria had transited from the conventional energy use to use of clean energy sources such as solar, wind, bioenergy, etc, though in gradual phases. Further findings revealed that there were some barriers to achieving energy transition plan and carbon neutrality in Nigeria. These includes; financial funding, technical-know-how, poor energy policy and energy market losses, infrastructure decay, environmental/ecological, legal and regulatory demands. Conclusion: In conclusion, it should be noted that for a sustainable energy transition process and mitigation of climate change in Nigeria, the enabling policy frame works should be revisited.
