ENVIRONMENT AND ENERGY 25 A change is as good as a holiday – or is it? South Africa faces major changes to its climate. This is evident in the Western Cape in particular, but other provinces are in dire need of water, too, like the Free State, Eastern Cape, North West Province, Limpopo, and the northern parts of KwaZulu-Natal. Andy Camphausen According to local researchers, our annual temperatures have increased by at least 1.5 times more than the global average in the past 50 years, and the trend is likely to continue. Climate change poses a significant threat to our water resources, food security, health, and infrastructure, among others. In a country where many people live from hand to mouth every day and where distinct differences in equality still exist, these effects of climate change are critical challenges to the development of our young and democratic economy. According to some UN agencies, more than 97% of the planet’s water is salty. According to the FAO — the UN’s Food and Agricultural Organisation — globally, rain, groundwater and surface water together equals 43 trillion m 3 . It takes around 2000–4000 litres per person per day to produce food and enough water for drinking. This all looks great, but is it? About 60% of the globe’s freshwater reserves are locked in the Antarctic. Of the rest, more than a quarter is located in Central and Latin America. What we can assume from these facts is that the global water crisis is one of governance. We need a plan of action to combat this in our country. All of us can contribute. We are all in the water game and it is everyone’s responsibility. We can leave the country for greener pastures, but the world is becoming overpopulated and the drive to build housing for our people is becoming more and more difficult. So those greener pastures may just become greyed from climate change in the country you choose. We are all here now, so why not take the plunge and assist with the plight of doing our jobs differently, but still being responsible in the same breath? www.plumbingafrica.co.za By Here are some ideas as to where we can assist, whatever your expertise: • If the climate becomes drier, the land use that seriously affects water catchments, such as misuse of wetland areas, changing the course of rivers, will place greater demands on water resources. Can we not improve this by inventing or assisting in this area? • Most people live in cities in South Africa, which is rumoured to rise to 75% urban population by 2050. As most cities are in excess of 100 years old, infrastructure — be it civil or mechanical — is ageing, broken, or maybe beyond repair. Can we assist municipalities with their challenges? • The risk of health-related diseases becomes an everyday reality when things either dry up or are over-watered like in the case of flooding. Either situation has dire consequences on health. Could we assist in ensuring that municipalities are using forward planning to eradicate health-related challenges? • Can we drive the assistance of many water-related programmes, be it the government or private society, to be the leaders of water-saving ideas — living, eating, and breathing it, 24/7? According to a recent survey, all cities and municipalities say investment is critical if adaption strategies are to be successful. As we are leaders in the water space, leadership and management can be identified as critical skills needed to protect urban and rural citizens alike against the threats of climate change in our country that we like to call home. PA A dramatic visual of the ultimate effect that climate change can have on earth — no matter where you go to. What we can assume from the facts is that the global water crisis is one of governance.
