The Impact

This article aims to examine the impact of climate change on food security in South Africa. For this purpose, the article adopted a desktop study approach. Previous studies, reports, surveys and policies on climate change and food (in)security. From this paper’s analysis, climate change presents a high risk to food security in sub-Saharan countries from crop production to food distribution and consumption. In light of this, it is found that climate change, particularly global warming, affects food security through food availability, accessibility, utilisation and affordability. To mitigate these risks, there is a need for an integrated policy approach to protect the arable land against global warming. The argument advanced in this article is that South Africa’s ability to adapt and protect its food items depends on the understanding of risks and the vulnerability of various food items to climate change. However, this poses a challenge in developing countries, including South Africa, because such countries have weak institutions and limited access to technology. Another concern is a wide gap between the cost of adapting and the necessary financial support from the government. There is also a need to invest in technologies that will resist risks on food systems.

The Impact

The advent of the COVID-19 pandemic and its crippling effects exacerbate many people’s vulnerability to food security across the world, including Africa. This article offers an explorative discourse on the implication of COVID-19 pandemic for South Africa’s food and livelihood security in the face of climate change. Using a scoping desktop review method, the article aims to provoke research and policy action and discourse on the subject matter. The article explores pre-and post-COVID-19 vulnerabilities in South Africa. It acknowledges the impact of climate change on food security and the situation of food security in South Africa pre-and post-COVID-19 pandemic. It then provides policy recommendations and expected outcomes to reconfigure the agricultural sector in the new sociopolitical and economic order necessitated by the pandemic. The article argues that reducing the stress posed by COVID-19 will require collaborative efforts and systemic thinking by stakeholders across all quarters. This will proffer workable solutions to mitigate the consequences of the COVID-19 pandemic on the food and livelihood options of rural dwellers in South Africa and their interconnectedness with the impact of climate change.

Community Based Adaptation

Purpose The study explored the impacts of climate change on water resources, and the community-based adaptation practices adopted to ensure water security in a rural community in Limpopo Province, South Africa. Design/methodology/approach The study was conducted in Limpopo Province, South Africa. The participatory approach was used to allow community members to share their challenges of water scarcity, and the measures they have developed to cope with inconsistent water supply. Findings The study results show that the community obtains water for household consumption from the reticulation system supplied by Mutale River and the community borehole. These resources are negatively impacted by drought, change in the frequency and distribution of rainfall, and increased temperature patterns. The water levels in the river and borehole have declined, resulting in unsustainable water supply. The community-based adaptation practices facilitated by the water committee include observance of restrictions and regulations on the water resources use. Others involve securing water from neighbouring resources. Originality/value This type of community-based action in response to climate change could be used as part of rural water management strategies under climate change.

The Impact

<p>The impact of climate change on the hydrological cycle and catchment processes has been extensively studied. In Wales, such changes are projected to have a substantial impact on hydrological regimes. However, the impact on the water abstraction capability of key sectors in the country, such as hydropower (HP) and public water supply (PWS), is not yet fully understood. We use the Soil and Water Assessment Tool (SWAT) to generate future (2021-2054) daily streamflows under a worst-case scenario of greenhouse gas emissions (Representative Concentration Pathway 8.5) at two large catchments in Wales, the Conwy and Tywi. SWAT streamflow output is used to estimate the abstractable water resources, and therefore changes in the average generation characteristics for 25 run-of-river HP schemes across Conwy and Tywi and the total unmet demand for a single large PWS abstraction in the Tywi. This unmet PWS demand is assessed using the Water Evaluation And Planning (WEAP) system under increasing, static, and declining demand scenarios. Mann-Kendall trend analysis is performed to detect and characterise the trends for both sectors.</p><p>Results show greater seasonality in abstraction potential through the study period, with an overall decrease in annual abstraction volume due to summer and autumn streamflow declines outweighing increases seen in winter and spring. For HP, these trends result in a projected decline in annual power generation potential, despite an increasing number of days per year that maximum permitted abstraction is reached. For PWS, under all future demand scenarios, annually there is an increase in the number of days where demand is not met as well as the total shortfall volume of water. Our results suggest that currently installed HP schemes may not make optimal use of future flows, and that the planning of future schemes should take account of these to ensure the most efficient operation is achieved. Moreover, PWS supply sustainability is under threat and will require management and mitigation measures to be implemented to ensure future supplies. Overall, our study provides a novel perspective on the future water resource availability in Wales, giving context to management planning to ensure future HP generation efficiency and PWS sustainability.</p>

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.
