Impacts Of Climate Change

Abstract Food security is one of the main goals in achieving the Sustainable Development Goal’s (SDG’s). Food security, natural disasters, and climate change are thought to be interrelated. Climate change contributes to natural disasters such as floods, landslides, drought, land and forest fires, resulting in reduced food production, increased food prices, and disrupted access to food distribution. Ultimately, the impacts of climate change and natural disasters are one of the main causes of hunger and affect all dimensions of food security. This study aimed to analyze the impact of climate change, natural disasters, and other determinants on food security in Indonesia using the Tobit regression. The data used was from 33 provinces in 2010-2018. Climate change was proxied by rainfall, while natural disasters were proxied by the frequency of natural disasters and facility damage due to disasters. The results showed that food crop production, GRDP per capita, and the average years of schooling had a significant effect on increasing food security. Meanwhile, rainfall and deforestation had a significant effect on reducing food security. On the other hand, although not significant, the frequency and damage to facilities due to natural disasters harms food security. The results of this study confirmed the importance of preserving forest biodiversity as an effort to achieve food security as seen from the negative effects of rainfall and deforestation on food security. In this case, deforestation was one of the contributors to climate change which in turn had an impact on the intensity of natural disasters. To achieve food security for the achievement of the SDGs, policies to reduce deforestation or forest conversion need attention as one of the efforts to mitigate the impacts of climate change and natural disasters.

Research on the impact of climate change on agriculture and food security is important, especially in the agricultural economies, not only to know the severity of impact but also the policies to be adapted to halt climate change and the technology to be used to mitigate the impact of climate change. The study was conducted in Kapiri Mposhi district of Central Province in Zambia to find out the impact of climate change on agriculture and food security. The objectives of study include to know the intensity of climate change and its impact on area under cultivation, late sowing of seed and damage of seed due to lack of water, fertilizer absorption reduction, food shortage, livestock, and productivity. The chapter also focuses on the sources of credit to the farmers.

The Impact

AbstractAgriculture is the backbone of Uganda’s economy, with about 24.9% contribution to the gross domestic product (GDP) as per the Uganda National Household Survey 2016/17. Agricultural productivity (yield per hectare) is still low due to the high dependence on rain-fed subsistence farming. Climate change is expected to further reduce the yield per hectare. Therefore, this study aims to evaluate the potential impact of climate change on maize yield in the Victoria Nile Sub-basin using the AquaCrop model. It further assesses the possible adaptation measures to climate change. The Hadley Centre Global Environmental Model version 2–Earth System (HadGEM2-ES) data downloaded from the Coordinated Regional Downscaling Experiment (CORDEX) was used to simulate maize yield in the near future (2021–2040), mid future (2041–2070) and late future (2071–2099). Results show that maize yield is likely to reduce by as high as 1–10%, 2–42% and 1–39% in the near, mid and late futures, respectively, depending on the agro-ecological zone. This decline in maize yield can have a significant impact on regional food security as well as socio-economic well-being since maize is a staple crop. The study also shows that improving soil fertility has no significant impact on maize yield under climate change. However, a combined application of supplementary irrigation and shifting the planting dates is a promising strategy to maintain food security and socio-economic development. This study presents important findings and adaptation strategies that policymakers and other stakeholders such as farmers can implement to abate the effects of climate change on crop production.

National Food Security

Agriculture sector, being the dominant user of fresh water (70%) is highly vulnerable to climate change in Pakistan. Increase in frequency of floods and drought, rising temperatures and changes in rainfall pattern across the country during the recent years are clear indicators of changing climate. Climate change has serious repercussions for national food security as farmers have limited knowledge and technologies for mitigating the adverse effects of climate change on crop productivity. This situation is expected to decrease yield of major food crops. There exists dire need to make an intensive analysis of situation to identify existing knowledge and technology gaps and suggest doable measures for multiple stake holders like policy makers, scientists and farmers accordingly. This review paper covers the impact of climate change on agriculture and presents strategies to adapt to climate change. Strategies at policy/government level include increased funds for research, improvement of national capacity building (training of trainers) and development of a localized smart early warning system for climate change related events. Key research areas being identified to address vulnerability include development of innovative water use efficient technologies, zone specific agronomic research, applied root research, organic farming to increase soil resilience and research on ground water recharge and quality using simulation models. Farmers shall be sensitized about the issue of climate change through education and every effort shall be made to make proper use of existing farm resources and technologies to live with the changing climate so that national food security is not compromised.
