Reports by the International Panel on Climate Change (IPCC) and the World Bank show that communities across South America are already feeling the impact of climate change today—and that these are likely to intensify in the future. According to the IPCC, the economies of most Latin American countries depend on agriculture, which means that climatic change and extreme weather events that affect farming also pose a tangible threat to economic prosperity and developmental goals in the region. A 2012 World Bank Report even predicts that South America will be one of the regions hit hardest if temperatures rose by more than the internationally recognised 2°C target. This post will highlight five of the central ways in which South Americans are experiencing the effects of climate change:

1. Temperature: In South America, climate change has led to a variety of temperature changes. While the widely-cited 2007 IPCC report observed an overall 1°C increase in temperature across South America over the past decade, there has been significant regional variation, leading to diverse effects. For instance, Bolivia’s highlands have actually cooled by 1°C over the past five decades, while there is some evidence for rising temperatures in the lowlands. In a 2009 World Bank Report, Drs. Lykke Andersen and Dorte Verner show that the contradictory trends of average temperatures have led to uneven social and economic effects of climate change in Bolivia. They estimate that the cooling experienced in the country’s highlands has reduced income in these areas by about 2–3 percent. In the country’s wealthier lowlands, no such negative trends were observed. This means that in Bolivia changes in temperature affect the population of the comparatively poor highlands disproportionately, compared to the wealthier lowland of the country. Read More »

Today, the time of the Winter Solstice in the Southern hemisphere, marks the beginning of the new agricultural year for the Aymara indigenous people of the Andean region. In June 2010, Bolivia’s President Evo Morales, an Aymara himself, decreed June 21 as an important national holiday: the Aymara New Year.

Although the celebrations center in the ancient ruins of Tiwanaku, with more than 50,000 participants in 2010, all over Bolivia, indigenous Aymarans gather on this typically coldest, longest night of the year to see in the sunrise. They brave the freezing temperatures in order to welcome the sun out of its winter season, characterized by short days and early darkness, and into longer days and more sunshine. Rituals back-dropped with traditional music abound and sacrifices of  llama, incense, alcohol, and coca are offered to Pachamama (mother nature/Mother Earth) until sunrise. All of this is in the hopes of enticing Tata Inti, the sun god, to heal the earth and give the farmers a good harvest. Read More »

“More and more and higher-level technology” is heralded as the way that the human population will eventually get itself out of the global troubles it has wreaked. Under-researched genetically modified seeds to be sold to poor rural farmers in India; financially, socially and environmentally expensive Three Dams Project in China; and ethically dubious biofuel alternatives made in order to stem the toxic air pollution of the global transport industry. Each high-tech solution has its merits and its downfalls, of course, but do we always need to be looking forward or could we learn something from our ancestors? Read More »

Meat production is thirsty business. Do you know much water do you eat? INESAD’s latest inforgraphic provides some real food for thought. Did you know, for example that a beef burger takes 2,400 litres of water to produce, compared to 170 litres for a vegetarian burger.

Did you know that passing up just one beef burger saves the water equivalent of 40 low flow showers? INESAD’s latest infographic aims to encourage diet-based water conservation. Love it, live it, share it.

March 22nd saw this year’s World Water Day kick off a series of upcoming events organised by the UN and other organisations to highlight global water issues.

Luckily, there is lots of good news, like the fact that half of the internationally agreedMillennium Development Goal on safe drinking water and sanitation has been met ahead of schedule. According to a joint report by the World Health Organisation and UNICEF:

“Since 1990, more than 2 billion people have gained access to improved drinking water sources.” Read More »

Climate change, water shortages, rising global pollution levels and food insecurity have made environmental sustainability the most pressing concern of our time. Improvements in production systems and agriculture, and advances in clean technology, will certainly help, but as the global population becomes more conscious of the issues facing us as a human race, we begin to ask ourselves what it is that we can do to help preserve our planet for centuries to come. More than in anything else, the answer to that lies in the diet choices we make.
