The study examined the impact of climate variability on yield of maize and yam in Cross River State, Nigeria. The specific objectives of the study were to determine the long-run and short-run impact of climate variability factors on yields of maize and yam. Data were sourced from the Nigerian Meteorological Agency (NiMeT) and Cross River State Ministry of Agriculture spanning from 1990-2016. Data obtained were analyzed using inferential statistics. Precisely, the model was estimated by the Ordinary Least Squares (OLS) multiple regression technique, which is within the Autoregressive Distributed Lag Bound approach and error correction testing framework. Both model-1 (maize yield) and model-2 (yam yield) passed through the conditions of the diagnostics and stability test. The study revealed that climate variables had a significant impact on maize yield both in the long and short-run. Based on the findings, it was concluded that proactive measures should be put in place to aid crop farmers adapt to the prevailing and looming threats of climate variability for the purpose of attaining the State’s food security balance sheet. To sustain this drive, an institutional and infrastructural support system is advocated in order to meet one of the goals of sustainable development agenda of the United Nations. Policy recommendations on how to cushion the impact of climate variability on the prescribed crops have been appropriately cited.

Climate change poses special challenges for decision makers in Indonesia related to inherent uncertainties in future climate projections and the intricate relations between climate change, physical and biological systems, and food security. At present, however, coastal and marine subregions do not have the adaptive capacity needed to overcome this challenge. This paper examines the impact of climate change on food security in coastal and marine Indonesia. It aims to inform decision makers with up-to-date information about vulnerability to climate change, and to facilitate the development of adaptation strategies informed by the experience and knowledge of experts. Climate and extreme weather hazards associated with the coastal and marine sectors cover different factors but are related to sea level rise, rising coastal water temperatures, and tropical storms and hurricanes. Potential vulnerabilities for coastal zones include increased coastal erosion which causes changes in coastline, loss of coastal wetlands, and changes in fish profiles and other marine life populations. Adapting to climate change will ultimately require more systematic integration of governance strategies, science, regulatory systems, policy, and economics at an international level to deal effectively with the wide range of impacts projected for Indonesia. This integration will be shaped through formal mechanisms such as the development or modification of laws, regulations, and policies.
