The fynbos vegetation that historically clothed the slopes of Table Mountain is highly inflammable. This has been worsened by the spread of alien trees that burn more intensely than the fynbos.
Fire hazards are influenced by three factors: weather, an ignition source and fuel loads. The first two are unpredictable. But fuel loads can be managed.
Losing archives has significant implications in a country like South Africa with a fraught and contested history because voices from the past, which may carry alternative histories, are lost.
Researchers have come up with a new framework that assigns an invasive species threat score to World Heritage Sites. This will improve how these species monitored and managed.
Too much ultraviolet radiation is dangerous for human health. Excessive exposure can cause skin ageing and sunburn and can induce melanoma, cataracts, ocular melanoma, and immunodeficiency.
Household rat poison is endangering caracals, and other wildlife species in Cape Town, that prey on poisoned rodents. If not managed, this can negatively alter the region’s ecosystem.
Humans - the very “carriers” who can spread dangerous microbes unthinkingly from their equipment and shoes - can instead become the first line of defence against a possible microscopic invasion.
A robust technique using the wonders of digital media has helped researchers understand how threatened species like frogs are faring on our globally changing planet.
