This work presents a systematic review of relevant literatures centered on the deforestation, desertification climate change hazards and agriculture related problems caused as a result of these natural and human activities with the hope of understanding the situation for better way out. Findings revealed that desertification affects about one sixth of the world's population, 70% of all dry lands, amounting to 3.6 billion ha, and one quarter of the total land area of the world. The worsening problem of desertification is quite glaring that an estimate of between 50 % and

This paper attempts to examine the relationship between climate change and pearl millet production in Nigeria. It discusses the origin, distribution of the species with some of their properties including production constraints in the Sub Saharan Africa and Nigeria in particular. Northern states of Nigeria were found to be the dominant producers of pearl millets with Sokoto state having a total cultivated area of 747,580ha. Pearl millet was also found to be the major crop amongst others, useful for minimizing the adverse effect of climate change, hence facilitating income and food security among farming communities. Major production constraint of the crop in the Sub Saharan Africa, particularly in Nigeria is yield reduction and/or total crop failure caused by erratic seasonal rainfalls, floods, failing soil fertility and poor crop management practices. Biotic stress due to weeds such as Striga spp as well as insect pests and diseases pestilences is a constraint. Therefore, appropriate climate change mitigation efforts to improve pearl millet production and enhance food security should be adopted in the Sub Saharan Africa and Nigeria.
