The application of climate smart agriculture technique has been identified as an important aspect in proffering solutions for most of the challenges to climate change mitigation as well as environmental and agricultural sustainability. Several biosensors and biosensing machineries such as nanoparticles/nanomaterials, polymers and microbes built-biosensors as well as their applications are now being used in most part of the world for solving some of the challenges in agricultural activities,

... production and its sustainability. However, it is significant to assimilate multifaceted methods for sustainable development of more effective biosensors that can possibly be used for diverse applications especially in the area of climate smart organic/biological agriculture for environmental sustainability. Smart monitoring employing biosensors will ensure that biochemical and other categories of contaminants are kept at bay from conceding the quality and safety of food via the mitigation of pest and pathogens that could affect agricultural produce. Hence, this study will attempt to provide an overview of what has been done from previous studies on biosensing technologies and their wide application in climate smart organic/biological agriculture as well as their role in environmental sustainability, and this will assist in proffering useful suggestions for future research studies as future contribution to knowledge for the advancement in agricultural and environmental sustainability.
