“…Rainfall distributions fluctuate widely through the country, following a north-south gradient with higher rainfall in the north and in the mountainous areas, where average annual rainfall can be up to 2000 mm. The annual average precipitation is 1030 mm, ranging from 1400 mm/year near the Zambezi basing to 300 mm/year in the south ( Uamusse et al 2017 ).…”

An updated checklist of Mozambique’s vascular plants is presented. It was compiled referring to several information sources such as existing literature, relevant online databases and herbaria collections. The checklist includes 7,099 taxa (5,957 species, 605 subspecies, 537 varieties), belonging to 226 families and 1,746 genera. There are 6,804 angiosperms, 257 pteridophytes, and 38 gymnosperms. A total of 6,171 taxa are native to Mozambique, while 602 are introduced and the remaining 326 taxa were considered as uncertain status. The endemism level for Mozambique’s flora was assessed at 9.59%, including 278 strict-endemic taxa and 403 near-endemic. 58.2% of taxa are herbaceous, while shrubs and trees account respectively for 26.5% and 9.2% of the taxa. The checklist also includes ferns (3.6%), lianas (1.7%), subshrubs (0.5%) and cycads (0.3%). Fabaceae, Poaceae and Asteraceae are the three most represented families, with 891, 543 and 428 taxa, respectively. The extinction risk of 1,667 taxa is included, with 158 taxa listed as Vulnerable, 119 as Endangered and as 24 Critically Endangered. The geographical distribution, known vernacular names and plants traditional uses are also recorded.

“…Their studies found an increase in maximum and minimum temperature in the Kainji dam in Nigeria, the Koshi river basin in the Himalayan region and Masinga Reservoir, Kenya. Miguel et al [43], on their part, found a significant increase in temperature between October-March for hydropower generation in Mozambique.…”

This study aims to determine a relationship between power generation and hydroclimate elements. The Mann-Kendall test, Sen’s slope tests, Pearson’s correlation and linear regression have been used for data analysis. The results of monthly hydroclimate elements showed mixed increasing and decreasing trends. The annual rainfall, maximum and minimum temperature showed an increasing trend, while evaporation showed decreasing trends. The annual inflow and outflow showed significantly increasing trends, while reservoir elevation showed a significant decreasing trend. The annual hydropower generation showed a non-significant increasing trend implying power generation has risen over the years. The Pearson’s correlation results showed a positive relationship between rainfall, hydropower generation while other climate elements showed a weak negative relationship. This relationship implies that climate factors play an insignificant role in power generation at Jebba dam. However, the consistently increased temperature trends in the Jebba dam could indicate climate variability and change. Contrary to other studies, we concluded that climate might not significantly influence hydropower generation at Jebba dam, Nigeria. Although continuing climate studies are encouraged, we recommended that authorities focus more on other factors for optimum power generation.

“…Due to its great extent, the average annual temperature is differentiated as follows: the northern region with 25.5 • C in the coastal region and 18.0 • C in the higher regions; followed by the central region with 25.0 • C in the coastal region and 20.0 • C in the higher interior regions, and finally the southern region with 23.0 • C in the coastal region and 25.0 • C in the interior region. The average annual rainfall reaches 1,030 mm, ranging from 300 mm/year in the southern region (e.g., lower in Gaza inland toward the border with South Africa and higher along the Maputo coast) to 1,400 mm/year in the Zambezi basin (Uamusse et al, 2017).…”

Mozambique supports a high diversity of native legume species, including many Crop Wild Relatives (CWRs). Among them, the still understudied genus Vigna is a particularly notable and promising donor of favorable traits for crop improvement. This study aims to provide an updated overview of Vigna CWRs diversity in Mozambique, defining a conservation strategy for priority target taxa and areas. A checklist of Vigna taxa was prepared and using five criteria (taxonomic group, ethnobotanical value, global and regional distributions, and ex situ conservation status), the prioritization of each taxon was determined. The distribution of Vigna native to Mozambique was studied and diversity hotspots were detected; gaps in in situ conservation were analyzed by overlaying species distribution with Mozambique’s Protected Areas Network. Maps predicting the differences between future conditions and baseline values were performed to investigate expected changes in temperature and precipitation in Vigna’s occurrence areas. There are 21 Vigna native taxa occurring in Mozambique, with the Chimanimani Mountains and Mount Gorongosa, as diversity hotspots for the genus. Following the IUCN Red List criteria, 13 taxa are of Least Concern, while the remaining eight are currently Not Evaluated. According to their priority level for further conservation actions, 24% of the taxa are of high priority, 67% of medium priority, and 9% of low priority. The important hotspot of Chimanimani Mountains is among the areas most affected by the predicted future increase in temperature and reduction of rainfall. The obtained distribution and species richness maps, represent a relevant first tool to evaluate and improve the effectiveness of Protected Areas and IPAs of Mozambique for the conservation of Vigna CWRs. The in situ gap analysis showed that 52% of the Vigna taxa are unprotected; this could be overcome by establishing reserves in Vigna diversity centers, considering the different types of habitats to which the different taxa are adapted, and by increasing in situ protection for the high priority ones. The ex situ conservation of Vigna is very limited and storing seed collections of these CWRs, is an essential component in global food security, as some taxa seem suitable as donors of genetic material to increase resistance to pests and diseases, or to drought and salinity. Overall, we provide recommendations for future research, collecting, and management, to conserve Vigna CWR in Mozambique, providing new data for their sustainable use in crop enhancement, as well as proposing measures for future conservation programs.
