Impacts Of Climate Change

<p style="text-align: justify;"><strong>Abstract:</strong> Industry concerns in Australia about the impacts of climate change have, to date, focused on the effects of warming, particularly shorter maturation periods. The effects of elevated CO<sub>2</sub> concentration (eCO<sub>2</sub>) on C<sub>3</sub> plant physiology have been extensively studied and suggest that eCO<sub>2 </sub>impacts on viticulture could affect grapevine shoot growth, fruit production and fruit composition. We previously used open top chambers (OTC) with an active heating system to study the effects of elevated air temperature (eTemp) on mature grapevines in the field. This system was augmented with the ability to elevate atmospheric CO<sub>2 </sub>and established in a mature Shiraz vineyard in a factorial combination of eTemp and eCO<sub>2</sub>. Three seasons of observations on the eTemp only treatment corroborated our previous study; all aspects of phenology were advanced, but leaf function was largely unaffected. In contrast, the effects of eCO<sub>2</sub> on phenology were small in the first season, but increased over the subsequent two seasons. Interactive effects of the treatments on gas exchange were observed; photosynthesis rates were significantly higher in the eCO<sub>2</sub>+eTemp treatment, compared to eCO<sub>2</sub> alone, suggesting that the likely future climate will have a larger impact on viticulture than might be predicted from experiments examining only one of these factors.</p>

Impacts Of Climate Change

Given its associated burden of disease, climate change in South Africa could be reframed as predominately a health issue, one necessitating an urgent health-sector response. The growing impact of climate change has major implications for South Africa, especially for the numerous vulnerable groups in the country. We systematically reviewed the literature by searching PubMed and Web of Science. Of the 820 papers screened, 34 were identified that assessed the impacts of climate change on health in the country. Most papers covered effects of heat on health or on infectious diseases (20/34; 59%). We found that extreme weather events are the most noticeable effects to date, especially droughts in the Western Cape, but rises in vector-borne diseases are gaining prominence. Climate aberration is also linked in myriad ways with outbreaks of food and waterborne diseases, and possibly with the recent Listeria epidemic. The potential impacts of climate change on mental health may compound the multiple social stressors that already beset the populace. Climate change heightens the pre-existing vulnerabilities of women, fishing communities, rural subsistence farmers and those living in informal settlements. Further gender disparities, eco-migration and social disruptions may undermine the prevention—but also treatment—of HIV. Our findings suggest that focused research and effective use of surveillance data are required to monitor climate change’s impacts; traditional strengths of the country’s health sector. The health sector, hitherto a fringe player, should assume a greater leadership role in promoting policies that protect the public’s health, address inequities and advance the country’s commitments to climate change accords.

Impacts Of Climate Change

The aim of this paper is to present climate change health related effects that may pose a challenge for South Africa to attain South Africa’s plans to achieve Sustainable Development Goal (SGD) 3. It examined South Africa’s preparedness to address the impacts of climate change in order to best achieve SDGs 3. Climate change is a challenging phenomenon, which has seen many people around the world being affected by its effects unaware and unprepared. Climate change affects weather patterns, for instance rainfall patterns and temperatures. Consequently, this resulted in draughts, floods, diseases, veld fires, high temperatures, changing times of floods occurrences and depleted water resources in Africa and the rest of the world. This has placed human life in danger. Considering the increasing burden of diseases, the United Nations (UN) adopted Sustainable Development Goals (SDGs) to address of poverty, hunger disease and want by 2030. However, climate change threatens the ability of countries to achieve this by the anticipated time. The researchers conducted an extensive content analysis by interrogating various sources of literatures sources that include journal articles, thesis, academic books, and documents written by the government of South Africa. The study reveals that that climate related deaths will increase between 2030 and 2050 due to these health impacts of climate change. The study reveals that South Africa, like many other countries in Sub-Saharan Africa faces threat of vector borne diseases, mental health, malnutrition, and diarrheal, and other disease resulting from water scarcity and heat waves. This comes because of high prevalence of drought, floods, and increased temperatures. The study recommends early awareness and new communication strategies for the promotion of mental health, heat education campaign and prevention of vector borne diseases.

AbstractTo identify and evaluate possible impacts of climate change on transportation in Limpopo province, it is necessary to define the scale and scope of the transportation system in the province and determine its sensitivities to climate change. This chapter, therefore locates the environment, climate change and the green economy matters in context. The science of climate change is explored, while the main sources of greenhouse gases are discussed. Additionally, the impacts of climate change in South Africa is outlined. Strategies to reduce greenhouse gas emissions (GHG) in the transport sector are provided.
