Droughts have been identified as an environmental hazard by environmentalists, ecologists, hydrologists, meteorologists, geologists, and agricultural experts. are characterised a decrease in precipitation over lengthy period, such season or year, can occur virtually all climatic zones, including both high low rainfall locations. This study reviewed drought-related impacts on the environment other components particularly, South Africa. Several attempts made using innovative technology earth observation climate information recorded studies. Findings show that country is naturally water deficient, which adds to fluctuation with average annual Africa being far below global of 860 mm per year. Drought Africa’s Western Cape Province, for example, has resulted employment losses province’s agriculture sector. According third quarterly labor force survey from 2017, industry lost almost 25,000 jobs across country. In province, about 20,000 these were direct impact income generation. Many linked drought events.

Increasing demand for food and environmental stressors are some of the most challenging problems that human societies face today these have encouraged new studies to examine drought impacts on production. Seeking discuss important issues in South African context, this study analyzed security one country's largest commercial agricultural land (Free State Province). Earth observation crop data were acquired from Application Extracting Exploring Analysis Ready Samples (AppEEARS) GrainSA databases, respectively years 2011/2012–2020/2021 over Free Province. Two crops namely, maize sorghum obtained database accordingly quantify two crops. The result reveals 2015 2018 affected by extreme events (<10%) where majority area was impacted. Years 2011, 2016, 2018, 2019 severely (>30%) impacted sector area. Findings further revealed production observed lowest recorded year 2014 with about 223,600 119,050 tons, respectively.

The emergence of ecosystem-based adaptation (EbA) has created a shift from the conventional approaches often accompanied by high costs, including conflicting interests associated with dense urban fabric and inflexibility. Therefore, EbA presents potential for more comprehensive, cost-efficient, multifunctional multidimensional measures in flood disaster risk management. Essentially, integrates biodiversity ecosystem services as an approach to climate change reduction. This study adopts descriptive exploratory analytical aimed at assessing trends events South Africa their management through EbA. reveals that between 1959 2019, several major floods have occurred, resulting losses life livelihoods significant infrastructure damages among others. Recovery taken years needed continuous investment. Unfortunately, many communities not been able "bounce back/bounce forward", despite all these efforts. revealed strategies can be instituted regionally nationally offer efficient or mitigation flood-prone areas. In general, utilising stabilise reduce impacts, minimise environmental impacts disasters developing innovative strategies. recommends increased awareness enhance universal adoption ameliorating risk.
