Abstract Extreme weather events, such as heavy rainfall, are being increased by climate change in various regions, and events often cause floods. This study examined the trends variability of extreme rainfall indices using daily data (1981–2023) from three sites at different socio-economic development spectra Vhembe District, Limpopo Province, South Africa. The analyses focus on annual total wet days (PRCPTOT), maximum number consecutive dry (CDD) (CWD), 1-day 5-day (RX1 day RX5 day), Simple Daily Intensity Index (SDII), exceeding varying amounts precipitation (R10, R20, R40) with greater than 95th 99th percentile (R95p R99p) 1981–2023 rainfall. We discuss observed light actual flood occurrences to establish linkages. Several statistically significant marginal changes were identified provided key insights into reported flooding district—flooding episodes mainly attributed increases (PRCPTOT) (R99p).

Abstract. Sub-Saharan Africa (SSA) is the region most vulnerable to climate change and related hydro-meteorological risks. These risks are exacerbated in rapidly expanding urban areas due loss degradation of green blue spaces with their regulating ecosystem services.

Locating, routing and deploying essential goods equipment are proactive disaster management strategies which received attention during recent decades. Many artificial intelligence (AI) based methods have been applied to respond disasters in the past decade. However, there lacks a systematic review on these approaches. This paper reviews such papers published over period of 2012–2022. These publications were examined according their goal using AI-based (e.g., for or locating deployment). We approaches adopted specific application areas within broad spectrum management. Based our review, we recommend few could benefit from methods, especially less explored area problem disasters. research would be helpful academics practitioners alike effectively adopting AI improve resilience response disastrous events.

In recent years, many parts of South Africa have been devastated by floods, impacting severely on the most vulnerable communities. Despite measures to reduce flood risk, and implementation adaptation measures, there is always a measure harm livelihoods, health wellbeing, economy, which persist far beyond events. This particular concern as events increased in frequency severity. A review literature, addressing risk management, mitigation coastal communities Africa, was conducted, determine how manage residual risks through resilience recovery programs, employing suitable tools, inclusive appropriate multidisciplinary stakeholders. study interrogated different approaches used assess social vulnerabilities, perception role communication information dissemination. Economic implications pertaining tourism, livelihoods loss natural built infrastructure were analyzed. Risk tools including early warning systems assessment models analyzed, various future scenarios explored. Possible opportunities presented negative impacts achieving SDGs The findings indicate that strengthening depends heavily collaboration across sectors cater for local needs.

The increasing frequency and severity of environmental disasters is cause for concern globally. This comes against the backdrop widespread criticism manner in which most countries handle disaster situations. In this article, South Africa's management appraised through a scoping review that highlights 'deeds' undertaken by major protagonists (the state, flood victims, other non-state actors) prior to, during, after April 2022 KwaZulu-Natal (KZN) floods disaster. premised on actor network theory (ANT) allows assessment nature "deeds" performed actor-network associations. Several gaps processes are revealed findings, including lack preparedness, mitigation, over subscription to response recovery with no robust capacity coordination among key stakeholders.
