Below you will find summaries and links to several of the more interesting ecologically-related stories to come out of South American countries in the past month. The list is not meant to be comprehensive or definitive, but hopefully you will find something that teases your interest. Enjoy.
“Very good night, here we are at Las Lomitas, on a radio of Mocase Via Campesina. This is our first time on air, our name is Paj Sachada, which means mount flight and we are running on solar power.”
This is the opening message of the radio station Paj Sachada and it was broadcasted by Margarita, who is only 17 years old.
This station is located on Las Lomitas, a remote spot in Santiago del Estero, Argentina. Because electrical power does not reach this place, the local people are using solar power to feed the radio station.
Scientists in South Africa are testing a genetically engineered tobacco plant which detects the presence of nitrogen-dioxide, a marker for landmines, to turn red, in the hope that it may eventually be used to clear mine fields in post-conflict zones around the globe.
The team is part of a joint initiative of University of Stellenbosch and the Danish biotechnology firm, Aresa, which has developed the “RedDetect” bio-sensor technology in a weed called Thales Cress.
The weed changes color from green to autumnal red when it detects nitrogen dioxide leaching from mines buried in the soil.
Because the weed is too small to be seen from a safe distance, the scientists went looking for a more viable alternative, and landed on the tobacco plant, which grows easily in most parts of the world, with a little help from genetic engineering.
Political leaders have a key role to play in developing and taking action to combat the world environmental degradation, according to a recent survey of 1,350 professionals in position to make or influence large climate-related decisions in their governments, companies, or other organizations across 120 countries.
The performance of key actors - particularly national governments - has been inadequate to date with rhetoric at much feted climatic conferences over-dominating action states the survey.
Respondents in the survey conducted by the GlobeScan for the World Bank, The World Conservation Union (IUCN), and the International Development Research Centre (IDRC), noted that there is currently little consensus on solutions to climate change.
In many parts of the world, the destruction of the environment is a daily reality in spite of the numerous statements that have been made about the terrible state of the environment.
But visionary political leadership can indeed influence a paradigm shift that can promote better treatment of the environment through requisite legal and policy mechanisms, but most importantly through political text that highlights the urgency of the matter followed by action.
As Kenyan Nobel Peace Laureate Wangari Maathai succinctly puts it the generation that destroys the environment may not be the one that pays the prize.
It is the future generations that will confront the consequences of today’s destructive activities of the current generation, she says.
“We have the obligation to lead the renewable energies development here in Chile. Currently we own 50 percent of the electric market and we want to keep this number also for the renewable energies,” said Rafel Mateo, the Chilean manager from Endesa. Endesa Chile, an Endesa Spain subsidiary, will invest 40 million dollars in the first solar power plant in Chile.
The chosen location for the plant is the northern part of Chile, possibly Tarapacá or Antofagasta. The northside of Chile is warm and desert, with sunlight almost all year long. Those attributes make the place ideal for a solar energy plant.
Argentina will produce massive wind power turbines. This country of South America is using some of the biggest generators with de Eolis-15, that has 1,5 megawatts of power and almost 80 meters tall.
Río Negro and Neuquén, two of the southeast provinces in Argentina, along with the Science and Technology Department from Cutral-Có and Plaza Huincul-both municipalities with oil royalties- have joined each other to develop the wind turbine Eolis-15, designed by Invap to make the most of high speed winds.
There is no consensus among water analysts on whether there will be global wars over water ownership.
According to UNESCO, globally there are 262 international river basins: 59 in Africa, 52 in Asia, 73 in Europe, 61 in Latin America and the Caribbean and 17 in North America — overall, 145 countries have territories that include at least one shared river basin.
UNESCO states that between 1948 and 1999, there have been 1,831 “international interactions” recorded, including 507 conflicts, 96 neutral or non-significant events and, most importantly, 1,228 instances of cooperation around water-related issues.
As a result, some experts argue that the idea of water wars is rather farfetched given the precedent of water cooperation that has been exhibited by many of the countries around the world.
“Despite the potential problem, history has demonstrated that cooperation, rather than conflict, is likely in shared basins,” says UNESCO.
Several months ago we told you that the Argentinean government was helping the rural zones with their power problems by installing solar energy. That time we are talking about solar energy kitchens for schools in Jujuy. Currently the government is installing solar cells in the province of Catamarca to empower schools, homes and public dependences.
Several days ago, I read a story about how Peru’s butterfly exports had increased 43% from January-April of this year. These are the butterflies that are pinned into glass frames for sale as gifts and souvenirs. I wondered if all of these butterflies included those that are exported illegally and those that are endangered. Questions of this kind were on my mind as just several days earlier my family had passed by a street vendor who sold animals illegally.
One of the animals was a baby monkey, caged and frightened. We live in the highlands region of Peru, so the monkey was far from its former home in the rainforest. My wife, who in the past worked as a biologist throughout Peru, told me that she thought this was an endangered monkey. As we walked home, I wished I had brought my camera. This I thought, is a story that needs to be pursued.
World Wildlife Fund (WWF) published a report in 2006 that documented the plunder of natural resources by human activity and warned that the globe itself could be outstripped in its capacity to support life, rendering the earth extinct in under 50 years.
Based on scientific data collected from across the globe, it revealed that more than a third of the natural world has been destroyed by human activity in just over the past three decades, because of, among others, increased emissions of green house gases into the ecosystem.
Unless consumption of natural resources was cut and the destruction of vital ecosystems was stopped, human life and that of thousands of other animals and plants would not be sustainable hence the suggestion that the earth itself could be extinct by 2050. In short, the demise of biodiversity will be the death of life on earth, as we know it.
Contrary to popular opinion, bicycling can potentially damage the environment due to the increased longevity of people engaged in physical activity, says Karl Ulrich, a Wharton Business School professor.
Ulrich argues that the greatest environmental peril society may face is the looming prospect of slowing the aging process, and bicycling potentially contributes to slowing aging.
Put simply, Ulrich says there is an underlying conflict between human-powered transportation, longevity, and environmental impact, which needs to be highlighted as the world seeks to find [...]
