Opis:: Evidence of changes in weather parameters like ambient temperature, precipitation, wind flow, etc., are prominently visible across the world. These changes have been reported to effect global crop yield. This review compiles both direct and indirect effects of climate change on global crop productivity with highlights on existing local and global scenarios. As a conclusion, it may be stated that thorough understanding of agricultural techniques and analysis of global change factors is highly essential for achieving sustainable agricultural yield over the upcoming years.

Opis:: Differential biomass and carbon stocks were investigated in vegetation of natural and artificial ecosystems in Akwa Ibom State. Three vegetation plots were used for each site. In each plot, three belt transects were laid and in each transect, vegetation were sampled systematically in ten 10 m × 10 m quadrat. Vegetation variables such as DBH, height of species were measured while their ages were estimated. The biomass and carbon stocks of species were estimated standardized allometric functions. The result revealed a total of 15, 30, 19 and 19 species in the mangrove, forest, arboretum and orchard, respectively. The biomass allocation in the various woody species components followed this decreasing order; stem > branches > leaves. The standing biomass in the ecosystems followed this decreasing order; forest (179.14 tons) > arboretum (53.94 tons) mangrove (33.03 tons) > orchard (17.14 tons). The carbon stock in the vegetation also followed this decreasing order: forest (89.65 tons) > arboretum (28.51 tons) > mangrove (16.52 tons) > orchard (8.57). Species such as Elaeis guineensis (in mangrove), Coula edulis (in forest), Temarindus indica (in arboretum) and Anacardium occidentalis (in orchard) had the highest values for biomass and sequestered carbon while species such as Alchornea cordifolia (in mangrove), Maesoboytra dusenii (in forest), Rauwolfia vomitoria (in arboretum) and Anthocleista vogelli (in orchard) had the least standing biomass and sequestered carbon. Conclusively, these results have practical implications in environmental monitoring and management, afforestation, forest protection and conservation, climate change and global warming.

Tytuł:: Climate change: causes, effects and the need for science education for sustainable development

Opis:: The world we live in has witnessed some drastic environmental imbalance in recent times. These imbalances have threatened sustainable development- which is the ultimate goal of man-environment relationship. This paper reviews the causes and effects of climate change on man and his environment with a view to using science education to solve the problems posed by climate change. Literature shows that climate change results mainly from human activities such as rapid deforestation for agricultural and industrial purposes, carbon dioxide emission from fossil fuel burning, carbon dioxide emission from burning gasoline for transportation, usage of chemical fertilizers on croplands and methane emission from animals, agriculture and arctic sea beds. The consequences of these activities include global warming, ozone layer depletion, greenhouse effect, rising sea level and acid rain. It is recommended here that the whole educational process be re-packaged to emphasize science education as a panacea for sustainable development. The argument here is that the educational institutions are the best media for the inculcation of proper morals and values. It is also recommended that teacher education programmes should allocate more funds to research in, and teaching of science in schools.
