‘Plant a tree – save our planet’

first_img26 August 2008The Department of Water Affairs and Forestry is calling on all South Africans to join in celebrating this year’s Arbour Week, starting on 1 September, by planting trees in their communities to help mitigate the effects of climate change.Tree planting remains one of the most cost-effective ways of addressing climate change, as trees and forests play a vital role in regulating climate, since they absorb carbon dioxide. Deforestation, by contrast, accounts for over 20% of the carbon dioxide humans generate, rivalling emissions from other sources.Trees also play a crucial role in providing a range of products and services to rural and urban populations, including food, timber, fibre, medicines and energy as well as soil fertility, water and biodiversity conservation.Arbour Week – themed “Plant trees: save our planet” – will set the stage for events around the country which will see government departments, non-government organisations, schools and communities planting trees.The campaign aims to promote improved knowledge of trees, particularly indigenous trees, and highlight the vital roles they play in the natural environment. It will also emphasise the role that ordinary South Africans in greening the country, just by planting and taking care of trees.SA’s million tree campaignThe week will also see the start of this year’s Plant a Million Trees Campaign, an initiative launched by President Thabo Mbeki and Water Affairs and Forestry Minister Lindiwe Hendricks in GaRankuwa, north of Pretoria last year.A total of 681 749 trees have been planted since the campaign was launched, with the Mpumalanga province having planted the most trees – 129 314 – to date.The department’s Arbour Week manager Tebogo Mathiane said that Arbour Week had become a huge success in recent years, with more and more people showing an interest in planting trees in their neighbourhoods.Billion tree campaignThe Billion Tree Campaign, launched by the United Nations Environment Programme and the World Agro-forestry Centre in 2006 as a response to the threat of global warming has already reached double its original target.The campaign, which can count of the patronage of Nobel Peace Prize Laureate and Kenyan Green Belt Movement founder Wangari Maathai and Prince Albert II of Monaco, has since planted two billion trees in 18 months. This year, the target has been raised to seven billion trees.Regional and national governments organised the most massive plantings, with Ethiopia leading the count at 700-million, followed by Turkey (400-million), Mexico (250-million), and Kenya (100-million). In terms of geographic distribution, Africa is the leading region with over half of all tree plantings.“Having exceeded every target that has been set for the campaign, we are now calling on individuals, communities, business and industry, civil society organisations and governments to evolve this initiative on to a new and even higher level,” said UN Environment Programme director Achim Steiner.Source: BuaNewslast_img read more

Ohio Ag Weather and Forecast — December 20, 2017

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Ryan Martin 171220Short term offers no change this morning. We have nothing different for today, tomorrow and even Friday. The next two days we see a similar pattern to yesterday, with a mix of clouds and sun. However, a cold front did slip through overnight, so temps may be slightly colder today than yesterday. On Friday we have clouds thickening up, and we can’t rule out some minor spits and sprinkles giving no more than a few hundredths to a tenth over about 40% of the state.Friday night gets a lot more active and that pattern continues through Saturday and even into early Sunday. Rains look to be very impressive and we are bumping up our top end of our rain range. WE are now calling for weekend rains of .25”-1.5” with the heavy rains staying in southern Ohio. We will not rule out thunderstorms in those heavy rain areas. The front is impressive and it has good moisture flow ahead of it. The map below shows rain totals through Saturday midnight.AS cold air blasts into the state on Sunday, we see some snow developing. However, we think the heaviest snow stays farther south and east of us. For now, we like 1-4 inches over about 70% of the state. Track is key here, and we will be waiting to put out our official snow totals until later tomorrow afternoon. But, it is looking more and more like we end up dodging a big bullet for snow on Christmas Eve through Christmas Day. Christmas afternoon should be mostly dry and sun should try to come out. However, the cold air continues to build, and we will be looking at brutal wind chills Christmas night.We are dry and very cold for Tuesday through Thursday. Temps will be well below normal. Then a clipper system rotates through the state for Thursday night and Friday, bringing potential for several inches of snow. This will be ahead of a stronger system lifting out of the southern plains for the start of New Year’s weekend. Temperatures remain very cold right on through into the New Year.In the extended period, we have another clipper for late the 1st into the 2nd that brings snows out of the Great Lakes right across the region. WE follow that with a cold front for the 3rd into the 4th that can also trigger several inches of snow. The cold holds through at least the first third of January.last_img read more
