Review of recently characterized Nigeria timber species for structural applications

The continuous rise of world population is putting much pressure on the housing and infrastructure stocks available to the society, thereby accentuating the need for more constructions and of course, more pressing demands on the depreciating natural resources. Today, the most used construction materials are concrete and steel, but the amount of pollutants deriving from their production has remained a source of great concern to the world. Finding solution to this environmental challenge has given rise to Sustainability Development Goals (SDGs), aimed at making the planet earth more conducive to living organisms. One of the viable approaches to reduce the high demand of construction industry on depreciating natural resources is the recourse to using more of renewable materials like timber. Timber is one of the few construction materials that have served all the ages of human lives in providing shelter. In this moment of pressing needs for more shelter and infrastructure, needed to make life more comfortable for man, the use of this renewable material must be sustained, but the strength characteristics must be known for more efficient and safe use. This research reviews recent characterization of some Nigerian timber species. This research emphasizes some good strength properties of recently reviewed Nigeria timber species, which will build the confidence of designers on safe judgment and choice of structural timber, help to reduce the cost of construction, thereby making residential houses more affordable to the lower class of the society. This will help to build a sustainable eco system for all.
