What is Nigeria national income size, growth rate and structural composition
Answers
Nigeria Gross National Product (GNP)
Nigeria Gross National Product (GNP) was reported at 433.449 USD bn in Dec 2019. This records an increase from the previous number of 378.867 USD bn for Dec 2018. Nigeria Gross National Product (GNP) data is updated yearly, averaging 51.463 USD bn from Dec 1960 to 2019, with 60 observations. The data reached an all-time high of 528.434 USD bn in 2014 and a record low of 4.174 USD bn in 1960.
Nigeria Gross National Product (GNP) data remains active status in CEIC and is reported by CEIC Data. The World Bank provides annual Gross National Product in USD.
Structural attributes and floristic composition of vegetation communities was investigated in the Kpashimi Forest Reserve, Niger State, Nigeria. The aim of the study was to describe the floristic composition and structure of the plant communities found in the study area. Biometric field inventory method; involving morphometric measurements, enumeration and application of allometric equations was employed for data collection. Vegetation variables including tree density, species diversity, tree girth, basal area, tree height, crown cover, shrub cover, and grass cover were measured within forty-eight sampling plots of 0.4096 hectares; distributed over the six vegetation physiographic units found in the area including riparian forest, savannah woodland, degraded forest, scrubland, grassland, and bare surface. For data analysis, the mean and coefficient of variation were determined from the data collected for each of the six vegetation physiographic units. The result showed that the Riparian forest is characterised by mean values of girth (1.16 metre), basal area (26.9 m2 ha-1) tree height (26.6 metre) and crown cover (68%). Savannah woodland recorded density of tree stand (0.0129 / m2) and diversity (13.75 Simpson’s diversity index), while Grassland and Bare surface classes are characterised by mean values of grass cover (89.9% and 51.1% respectively). Scrubland is characterised by mean value of shrub cover (64.8%); but with comparatively low trunk diameter, crown cover, tree height and tree density. The study area is thus characterised by a mixture of plant communities that vary in composition, diversity, heterogeneity, structure and complexity. This study presents acquired baseline information on the landscape vegetation structure and composition which could be useful for characterizing a typical savannah vegetation structure and composition. The data obtained could also provide a reference scenario against which future assessments could be compared; in order to understand the dynamics of vegetation communities.
