Climate change is real and happening now with severe and diverse impacts being felt all over the world. While Africa is the least contributor to greenhouse gas emissions, she is the most vulnerable and has been the hardest hit by the impacts of climate variability and climate change. There has been a rise in annual temperature and changes in rainfall patterns particularly frequency in floods and droughts.
The impacts of climate change effects are economic, environmental and social. Africa’s vulnerability to climate change is amplified because we are heavily reliant on rain fed agriculture. Research has shown that rainfall in Africa (one of the global very water scarce regions) could drop by about 10% for the period 2000-2050. A fall in the rainfall received poses a great challenge because over 90% of arable land in sub-Saharan Africa is under rain-fed agriculture (Misra, 2014). Research indicates that about 67% of this land will be lost to agricultural droughts by the year 2025 and the output is projected to drop by about 50% by the year 2020 (A, 2014). This means that African countries are going to be put under more pressure to ensure that their populations are not undernourished and food insecure which is already a challenge at present.
The current and projected impacts of climate change on food security in Africa calls for proper adaptation mechanisms to be put in place. Adaptation involves reduction in risks and vulnerability through the actions of adjusting practices, behavior, processes in order to respond to the risks posed by climate change (John R.Porter, 2014). Adaptation to climate change will involve changes in the decision making structures (social or institutional) that influence the making and implementation of policy. This policy changes should strengthen the conditions that favor effective adaptation including investing in new infrastructure and technologies (Jane Kabubo-Mariara, 2015). They will also safeguard the agricultural sector against the effects of climate change and go a long way in alleviating food insecurity in the region.
There is also the need to merge climate change scientific research with existing indigenous knowledge on the climate. In various African communities agro-pastoralists are known to predict drought through the observation of the flora, fauna, moon and wind (John R.Porter, 2014). At present there is a mismatch between the uptake capacity of communities and the volume of scientific information released on climate change. Therefore, there is a need for proper dialogue and consensus between the researchers and local communities as to how best to disseminate information on climate change adaptation and mitigation measures so that the communities benefit. To this regard there should be exploration of the indigenous knowledge in the traditional prediction mechanisms in these communities and how this can be integrated into scientific information for the benefit of rural communities. The rural communities’ adaptive capacity should also be enhanced through creation of awareness on the impacts of climate change and capacity building initiatives on adaptation and mitigation mechanisms.
The adaptation of crops will also play a vital role in ensuring food security for Sub-Sahara Africa as well. This would involve the altering of cultivation, sowing and adapting to new crop species that are drought resistant or require little water to survive (Heather E. Thompson, 2010). In Africa most of the farmers practice small scale farming and therefore intercropping (Mouk Bernard, 2012) would play a big role in increasing the productivity per unit of land. Studies show that adaptation of new crop species and altering planting seasons can increase the yields up to 23% (John R.Porter, 2014). Funding also needs to be availed by the government and the private sector so that there is more research done in breeding drought tolerant crop varieties.
To ensure that the continent is on the right track in implementation of the climate change adaptation mechanisms the different initiatives and mechanisms put in place will have to be regularly monitored and evaluated. This will help in providing sufficient information on what the impacts of these initiatives are towards ensuring food security. It will also allow for incremental changes to be made as more data and information becomes available on the impact of climate change on food security.
