Using a solar-powered pump gives you the flexibility to operate your garden fountain just about anywhere on your property, freeing you from using a pump that is tethered to an electrical outlet. Plus, swapping an electrically powered pump for a solar-powered pump enables you to transform your garden fountain into an environmentally friendly, or a “green,” water feature. The solar-powered pump’s initial expense pays off because the garden fountain no longer draws electricity; that factor reduces your electric bill.
Photovoltaic (PV) systems are used to pump water for livestock, plants or humans. Since the need for water is greatest on hot sunny days the technology is an obvious choice for this application. Pumping water using PV technology is simple, reliable, and requires almost no maintenance.
For farmers with a creek running through their properties, using a solar powered water pumping solution means less fouling of waterways and far less erosion of banks. It can also lead to better pasture management as livestock will be able to access water via multiple distribution points.
December temperatures in London have been warmer than July’s. Scotland is balmier than Barcelona. Artificial snow covers European ski slopes. Africa faces its worst food crisis in a generation as floods and droughts strike vulnerable countries.
With unusual weather from Britain to Australia, scientists are blaming climate change – but also the natural phenomenon called El Niño, which is raising temperatures and disrupting weather patterns. A double whammy then, but how disturbed should we be as the records tumble?
For the second year running, Mbalavala’s maize fields, which should have been planted months ago, lie empty; the soil in vegetable gardens is like sand and what little water there is from an emergency borehole must be shared between cattle and people.
Vascos Jaima Chilande, the Mbalavala headman, lists the rivers that nearby villagesusually dam to collect water. “Bambene, Matlavane, Gomaje, Chichaquare … They have all dried up. The government dug a borehole 150 metres deep, but it is not enough. Today there is water only for the animals.”
Severe droughts and floods triggered by one of the strongest El Niño weather events ever recorded have left nearly 100 million people in southern Africa, Asia and Latin America facing food and water shortages and vulnerable to diseases including Zika, UN bodies, international aid agencies and governments have said.
New figures from the UN’s World Food Programme say 40 million people in rural areas and 9 million in urban centres who live in the drought-affected parts of Zimbabwe, Mozambique, South Africa, Zambia, Malawi and Swaziland will need food assistance in the next year.
El Niño is defined by above-average sea-surface temperatures in the eastern and central equatorial Pacific Ocean. These sea-surface temperatures cycle from warm to cool, relative to average, over a several-year period. When the sea-surface temperatures in the same area of the Pacific Ocean are cooler than average for a few months, a La Niña pattern has developed.
“El Niño will transition to neutral conditions early this summer, then perhaps toward a weak La Nina during August or September,” according to AccuWeather Chief International Meteorologist Jason Nicholls. “Because of this and other factors, we expect rainfall to return toward average over a large part of India, Malaysia and Indonesia.”
