Dataset of dendrometer and environmental parameter measurements of two different species of the group of genera known as eucalypts in South Africa and Portugal.

plantations are a crucial global resource, offering raw materials for industries across five continents, including renewable energy sources, recyclable fibers, and eco-friendly wood products. To support sustainable management, ten wireless dendrometer and environmental sensor systems were deployed on trees-six in Stellenbosch, South Africa, and four in Leiria, Portugal. These systems measure tree stem growth, air and soil conditions, and transmit data via LoRaWAN to a cloud-based platform (ThingSpeak), with local SD-card backups.

Dataset of indoor air parameter measurements relating to indoor air quality and thermal comfort in South African primary school classrooms of various building infrastructure types.

In the resource-constrained South African education sector, infrastructure considered temporary or a backup in other countries is used as permanent classrooms, primarily but not exclusively in lower-income areas. Children's cognitive performance and comfort are directly impacted by indoor air quality. Temperature, relative humidity, particulate matter and CO levels, substantial determinants of air quality and thermal comfort, have not been investigated across different classroom building and infrastructure types.

First report of aeroponically grown Bambara groundnut, an African indigenous hypogeal legume: Implications for climate adaptation.

Global agricultural production is currently limited by negative climate-related hazards such as drought, uneven rainfall and rising temperatures. Many efforts have been put in place by government and non-government agencies to mitigate the challenges of climate change in the sector. However, the approaches do not seem feasible due to the growing demand for food.
