Climate Change

Climate change and variability is an important component in spearheading adaptation options. Environmental change related to climate change shows altered the rainfall patterns, amplified drought cycles, increased the frequency of severe weather conditions and increased agricultural pests and diseases. More importantly climate change has resulted in declining crop production not only in Zimbabwe but in the whole of the Southern African Development community (SADC). Smallholder farmers have become vulnerable to climate change. Cotton production in Zimbabwe has been on the decline mainly due to climate change and variability. Maize production and other small grains like sorghum have also been on the decline. Climate change has therefore affected staple crops, subsistence production and livestock production in general. Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results. Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications. The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
