Climate Change and Food Security: A review of current and future perspective of China and Bangladesh
This review has mainly focused on China and Bangladesh, as taken in some parts of comparison due to climate changes (CC) affected the country. The study implicated a range of socioeconomic and agro-economic literature that was developed subsequent two different development trail linked with the Intergovernmental Panel on Climate Change (IPCC) pessimistic and optimistic scenarios. The food security index (FSI) has proven to be a powerful and reliable quantitative cause-effect analysis tool. Analysis of the literature results compared with other factors such as agricultural land area, population growth and GDP growth, showed that CC has only a modest positive impact on food security. Overall, socio-economic development pathways have a major impact on future food security trends in China and Bangladesh. Furthermore, emphasis on environmental sustainability, the impartial expansion path associated with the pessimistic emissions scenario, has proven to be far better in ensuring food safety than the other optimistic path. In regression analyzed literature, it was found that yield growth rate was a much better indicator in food security analysis than crop yield per season. Therefore, the yield enhancements on a yearly basis are highly consequence in ensuring food security for the countries with a big sized and densely populated region like China and Bangladesh. The comparatively lower FSI, values recommended that per capita food consumption in China is on a stable growth while Bangladesh would face deficiencies. Therefore, there is a need to focus more on food safety and balanced nutrition, taking into account climatic conditions. The review information derived from the study is similarly suitable for formulating climate change and agricultural relevant planning and policies.
