The agricultural and environmental sectors are plagued with challenges. In agriculture, soil infertility and the subsequent quagmire of poor crop yield, has always been a major problem that limits worldwide agricultural productivity. Major environmental concerns, including Climate Change and Soil Pollution, are receiving continual attention from key stakeholders. Efforts are hence being directed at curtailing or mitigating the devastative consequences of these man-made ‘monsters’. Recently, agricultural and environmental research reveals biochar to be a veritable technology that could be used to deal with some of these concerns. Biochar has the ability to have impact upon important soil properties, such as the raising of soil pH and water holding capacity, the attraction of beneficial fungi and microbes, improvement of cation exchange capacity (CEC), induce high carbon sequestration ability and nutrient retention capacity. Moreover, its large surface area makes it a potential remedy to several identified challenges. This review, therefore, critically highlights the importance of biochar, as well as the various ways of harnessing biochar technology towards global food security and environmental sustainability.

Biosphere Reserves all over the world are areas that are deliberately and purposely kept to promote green economy and most importantly mitigate the effect of Global warming and climate change. The problems of climate change arise from the higher concentration of greenhouse gases in the atmosphere which exert a warming effect on the earth. Control of anthropogenic sources and greenhouse gases are constantly discussed and extensively researched in this matter, while the significance of microorganisms remained neglected. Although microorganisms has a contributory effect in global warming as in the case of methanogenes in the rumen of ruminants which has been implicated to increase the environmental methane gases during digestion, the role they play in converting greenhouse gas to useable form in the soil and water hence, reducing global warming cannot be over emphasized. The current review aimed to stress the neglected global importance of microorganisms in climate change. Overall, this review further support the key role biosphere reserves play in protecting soil and plant microorganisms in response to climate change control.

Entandrophragma angolense is a tropical tree species with a very slow growth rate. To overcome this barrier, a study on the effect of organic amendment on the growth rate of Entandrophragma angolense seedlings was conducted in the nursery section of the Department of Forestry and Wildlife, University of Benin, Benin City, Nigeria. Herein, 2kg polythene pots, each containing top soil were all amended with Poultry droppings (PRD), Cow dung (CWD) and Compost (CPT) at a ratio of 2:1, while top soil alone served as the control. Employing a completely randomized design (CRD), growth variables were recorded on a fortnight basis. The seedlings were assessed for height, number of leaves and collar diameter for a total period of 20 weeks. Fresh weights and total dry weights of the seedlings were also determined at the end of the experiment. No significant difference (p>0.05) was observed in the effect of organic amendments on the plant mean height and number of leaves throughout the study period, however, a significant difference was observed in collar diameter at 2 weeks after treatment and 12 weeks after treatment alone. Organic amendment was found to influence general biomass production in the specie, although there was no significant difference (p>0.05) in stem biomass production. Conclusively, organic amendment can be said not to have significantly (p>0.05) affected the growth of E. angolense, while this cannot be said of the biomass production, albeit at a low level of significance.
