“…Ayantobo et al (2017) evaluated drought hazards of mainland China from 1961 to 2013 based on a univariate frequency analysis, and found that the distribution of drought frequency in China decreased both from west of east and from north to west. Ogunrinde et al (2021) explored the variation of drought severity and its correlation with climate change in the Sahel region of Nigeria from 1981 to 2015 by Mann-Kendall test, the findings demonstrated that the drought severity exhibited an increasing trend, and a slight change of rainfall will not have a significant effect on drought or the severity of drought increase.…”

Against the backdrop of global climate change, the response characteristic of meteorological drought is of great concern, especially in the arid or semi-arid regions. By employing the Standardized Precipitation Index (SPI), TPFW-MK test, Run Theory, Moran’s I, and General G, the spatio-temporal evolution characteristic of drought was clarified and the spatial autocorrelation of local and global drought characteristic variables was explored based on the meteorological data from 122 stations in Northwest China (NWC) during 1960–2018. The results indicated that the drought situation of NWC was improving regardless of annual or seasonal scale. According to the Z-statistics by the TPFW-MK test, there existed an obvious wet trend in west NWC and a slight dry trend in east NWC. The center of gravity migration model revealed that the gravity center of SPI moved towards higher latitude over the last decades, there was a northwest (1960–1990) and northeast (1990–2018) variation in the covering shapes of the standard deviational ellipses of SPI, and the spatial distribution of SPI tended to be concentrated. Meanwhile, the distribution pattern of drought characteristics suggested that more droughts occurred in east of NWC, which were less harmful while fewer droughts happened in west NWC, which brought greater drought damage. The results of global Moran’s I (GMI) indicated that both annual and seasonal drought variables were characterized with significant spatial autocorrelation, the spatial distribution of winter drought variables was more disperse than other seasons, while the damage of summer and autumn drought was bigger than that in spring and winter. Besides, the results of local Moran’s I (LMI) showed that there was obvious agglomeration in the overall distribution of drought characteristic variables, which had a seesaw effect. The spatial distribution of hot spots and cold spots at different confidence levels indicated that Shaanxi Province experienced the most droughts but with shortest duration and lowest severity while northwest Xinjiang had the fewest droughts with longest duration and highest severity. The results of revealing the drought development process and identifying the location of drought aggregation will provide references for supporting climate adaptation strategies and preventing drought-related loss.

“…Even though they are known to have technological and economic problems [20] renewable energies unlike fossil fuels do not have devastating impacts on the environment [21,22]. Greenhouse gases emission (GHG) is also a major contributor to climate change and environmental degradation in many parts of the world including Nigeria [23][24][25][26][27]. Energy plays a major part in the process of development of any nation as its cost directly affects the prices of goods and services [28,29].…”

Due to the potential depletion of fossil fuels and the need for the shift from its use to combat the aggravated impacts of climate change, the unsustainable use of these conventional fuels has been widely recognized. This has prompted commercialization of biofuels as an alternative sustainable fuel. This study summarizes the potential of third-generation biomass feedstocks, algae, for biofuel production on the example of Nigeria, where most biofuel plants still use first-and second-generation feedstocks, which have led to food and land mass competition. It is shown that the production and consumption of third-generation biofuel is at its infancy in the coun-try. It was also found that the climatic conditions in Nigeria are conducive for the cultivation of microalgae, which are the primary sources of the third-generation biofuel, even though there are barriers such as inadequate reliable resource database for investment decisions and technical expertise to develop and deploy biofuels in commercial form. The large population of Nigeria is a potential market for biofuel, therefore, commercialization of the third-generation biofuel can be a viable alternative energy source to conventional fossil fuels and it can generate employment for many in the country.
