In the version of this Article originally published, ammonia and NO emissions (and associated N deposition), nitrate leaching, and the CO 2 emitted during urea hydrolysis following application to land were all accidentally omitted in the comparison of the greenhouse gas impacts of using ammonium nitrate and urea to produce wheat grain. The correction has resulted in the changes detailed below. blue points. Both panels have been updated). In the caption of Supplementary Fig. 3, the Spearman's rank coefficient for panel b read "0.97 (<0.001)"; this has been updated to "0.99 (<0.001)". The sentence "Our GLMMs of data from a three-site experiment varying the N fertilization regime revealed a complex relationship between GHG and land costs (Fig. 2c; Supplementary Table 2), driven by divergent responses 28 to adding ammonium nitrate (which lowers land costs but increases embodied GHG emissions) and adding urea (which lowers land costs without increasing GHG emissions per unit production, but at the cost of increased ammonia volatilization)" has been updated to read "Our GLMMs of data from a three-site experiment varying the N fertilization regime revealed a clear trade-off between GHG and land costs (Fig. 2c; Supplementary Table 2), with fertilization using either ammonium nitrate or urea lowering land costs but increasing GHG emissions per unit production.

The renewed quest for sustainable economic development which is synonymous with sustainable agricultural development and hence agricultural sustainability impelled this study titled “Determinants of Agricultural Sustainability in Southeast Nigeria”. Southeast Nigeria is located within latitudes 5oN to 6o N of the equator and longitudes 6oE and 8oE of the Greenwich (prime) meridian (M.S corporation, 2009). Multi-stage sampling technique was used to select a sample of 312 cassava based food crop farmers from whom data were collected using structured and validated questionnaire. Data bothering on the respondents’ socio-economic characteristics, the type, quantity, and sources of inputs used and output produced were collected. These were analysed with the use of descriptive statistical tools and ordinary least square multiple regression analytical tools. Result showed that factors such as farm size, annual income, household size, level of education, and climate change are significantly and inversely proportional to sustainability level of farmers, while labour cost was significantly but directly proportional to agricultural sustainability. It was concluded that, efforts should be made at both micro and macro levels of government to improve on the mitigation and adaptive strategies of climate change available to farmers by making such more affordable, available and user friendly through extension education on the appropriate uses of such technologies in a more sustainable manner.

Evidence of Climate change impacts on Agric and Food security in Nigeria.pdf

Change in climate and consequent global warming are posing threats to food security in many developing nations including Nigeria because of the climate-dependent nature of agricultural systems and lack of coping capabilities. The spatiotemporal pattern of temperature and rainfall of Nigeria between 1901 and 2005 (105 years), using temperature and rainfall data to support the concept of regional climate change and its impact on Agriculture and food security was in-vestigated. Also assessed was the level of agriculture funding and output in Nigeria. Mean annual air temperature and rain-fall data between 1901- 2005 (105 years) were obtained from Food and Agricultural Organization publications, National Bureau of Statistics, Central Bank of Nigeria bulletin and National Meteorological Agency. Descriptive statistics were used to analyze the data. The results showed that within the period of 105 years, rainfall decreased by 81 mm with increasing temperature of 1.1℃. The unpredictability of rainfall and steadily increasing air temperature were observed from 1971-2005. The total federal budget between 2001 and 2005 averaged 824 billion Naira per year of which very small amount (14.7 billion (1.8%)) went to agricultural sector. The actual spending was 681 billion Naira per year with 11.4 bil-lion Naira for agriculture. Over 25 years, there were low and dramatic walloping of public spending in agriculture relative to large size and importance of agricultural sector in the economy. There is a continuous rise in output from 1987 to 2000 before it dropped in 2001. Land degradation, desert encroachment, drying up of surface waters, coastal inundations, and shift in cultivated crops over time affected the food security in Nigeria. The current available data showed that Nigeria, like most parts of the world is experiencing the basic features of climate change. Therefore, Nigerian government/ private sector partnership should encourage agricultural, industrial and domestic practices which will not contribute to the emission of greenhouse gasses.

Impact of Climate Change on Sustainable Food Production In Nigeria

Scientific Applications Research eConference SciAppRes-eCon2023, 2023

The interconnectedness of climate change and food production is a Siamese twin that cannot function without each other. The direct effect of climate change on food production can come in diverse ways, including changes in average rainfall, temperatures, extreme climate, and changes in terms of pest and disease manifestation. Thus, understanding the Impact of climate on food production in Nigeria necessitated this research. The methodology adopted a systematic literature review to locate and broadly synthesise research on climate change, the food security situation in Nigeria, the significant Influence of climate change on food production, and the threats posed by climate variations on Quality food production in Nigeria. Two inclusion criteria were created to screen for relevant studies from the literature: (1) journal articles published between 2000 and 2021 and (2) keywords that are related to the issue under consideration. This approach uncovered 47 articles published between 2000-2022 and 4 online expert opinion articles appropriately referenced. Evidence shows that extreme temperature and disparity in rainfall patterns are the two climate change variables that have a high impact on quality food production in Nigeria. Conclusively, we posited that the rising numbers of Nigerians starving and malnourished point to the fact that food security in the country is unimaginably low and, if not addressed, would continue to stimulate hunger. We recommend that sustainable farming systems, adaptations of new technologies, and innovations must be incorporated. Also, Support from the government at the federal and state levels is central and essential to achieving the goal of a food-secure nation.

The Potential Impact of Climate Change on Nigerian Agriculture

2016

This report examines how extreme weather conditions have affected the mean and variance of the yield of 18 food crops in Nigeria over a period of 42 years (1971-2012). The analysis at the State level was reduced to five Agricultural Transformation Agenda (ATA) priority crops and covered 22 years (1991-2012) due to data scarcity. The framework for the analysis consists of a stochastic production function suggested by Just and Pope (1978, 1979). The results show that the productivity of more than half of the staple crops in Nigeria is threatened by increase in total annual rainfall and extreme temperature nationally and across states in Nigeria. However, such increase is found to have beneficial effects on the productivity of a few crops grown in Northern Nigeria. The economic impact shows that extreme temperature will cause a considerable annual loss in value for most crops except few that are are grown mainly in Northern Nigeria (Borno, Yobe, Kaduna, Kano and Sokoto states) such as millet, melon, and sugarcane. Résumé Ce rapport examine comment les conditions météorologiques extrêmes ont affecté la moyenne et la variance des rendements de 18 cultures vivrières au Nigeria sur une période de 42 ans (1971-2012). Du fait de l'absence de donnees, l'analyse au niveau des Etats s'est limitée aux cinq cultures prioritaires identifiees par l'Agenda de Transformation Agricole (ATA) et couvre une periode de 22 ans (1991-2012). Le cadre de l'analyse consiste en une fonction de production stochastique proposée par Just et Pope (1978, 1979). Les résultats montrent que la productivité de plus de la moitié des cultures de base au Nigeria est menacée par l'augmentation de la pluviométrie annuelle totale et les températures extrêmes à l'échelle nationale et à travers les Etats au Nigeria. Cependant, cette augmentation se trouve avoir des effets bénéfiques sur la productivité de quelques plantes cultivées dans le nord du Nigeria. L'impact économique montre que les températures extrêmes entraîneront une perte annuelle de valeur considérable pour la plupart des cultures, sauf quelques-unes qui sont cultivées principalement dans le nord du Nigeria (Borno, Yobe, Kaduna, Kano et Sokoto) telles que le mil, le melon et la canne à sucre.

Worldwide emphasis has been placed on designing approaches with regard to the needs of sustainable development. Climate-Smart Agriculture (CSA) is one key agricultural development approach aimed at sustainably increasing productivity and resilience, while also reducing/removing emissions of greenhouse gases. Although many countries will be expected to adopt this approach, its applicability in an African context is not very clear, well studied nor has its sustainability been assessed. We used the Sustainability Assessment of Energy Technologies Framework to assess the applicability of CSA in combating climate change, desertification and improving rural livelihood in an African context. We also assessed the opportunities and constraints to the adoption of this approach in Northern Nigeria. Data was collected using key informant interviews and field observation to assess the current status of agriculture in Northern Nigeria. The results showed that CSA is strong in aspects such as participation and sustainable use of resources but weak in aspects of compensation and equal distribution of benefits and costs. Many smallholder farmers have inadvertently practiced CSA as part of the traditional farming system. While the existence of CSA in current practice is a major element in its favour, the lack of a coherent climate mitigation approach and poor institutional structures are both detrimental. Sustainable agriculture will require a wider societal change towards appreciating the balance between agriculture and environmental change. We suggest four main areas in need of urgent change: political commitment, human and financial investment, incentives and information.
