How a mining conflict led to the political emancipation of a community in Northern Greece.

#Skouries - a story of political emancipation

Author: Evi Papada  
 

skoyriesMining conflicts are increasingly surfacing globally due to complains over mines and pollution of water, soil and land occupied as well as over transport and waste disposal. The Skouries forest in Halkidiki has been at the center of a hot dispute between the mining company, Hellas Gold, a subsidiary of the Canadian mining giant Eldorado Gold and local communities. The company claims that an ambitious plan for mining of gold and copper in the area- including deforestation and open pit mining with excavation and everyday use of explosives- will benefit the region through the creation of some 5,000 direct and indirect jobs, while local residents argue that the planned investment will cause considerable damage to the environment and livelihoods, resulting to many more jobs losses in the existing sectors of the local economy (farming, pasture land, fisheries, beekeeping, food processing and tourism). The residents’ claims are supported by research conducted by various independent scientific institutions including the Aristotle University of Thessaloniki and the Technical Chamber of Macedonia. In addition to legitimacy questions underpinning the transfer of mining rights from the Greek state to the aforementioned company [1], the Environmental Impact Assessment produced by El Dorado has been found to contain gross methodological discrepancies and whilst the public consultation process could be at best described as cosmetic [2].

Permaculture and water catching earth


Permaculturists

Forest Hills farm catches rain for irrigation

Long before they heard the word “permaculture,” Forest Hills residents Terry Jo and Dave Bichell had embraced the tenets of organic gardening to create sustainable spaces on their Old Hickory Boulevard farm. Permaculture gave them the tools to overcome drought and flooding.

“Permaculture is a way of growing that uses the land to soak up and store water,” Terry Jo explained. “You use the natural features of the land and plant trees in such a way to hold water, and use plants to help nourish each other without fertilizers.”


The farm is a remnant of a historic plantation, she said, and the land had been used for pasture by previous owners. She was committed to avoiding pesticides or fertilizers, so she set out to see what could be grown on pasture land without alteration. “We grew a crop of hay for a couple of years, because at that time that was about all we could grow without using irrigation and pesticides.”

Principles of Water Management for People and the Environment

Michael Acreman, Freshwater Management Adviser to the IUCN, Institute of Hydrology, United Kingdom

Water, the Environment, and Population

Water is the lifeblood of our planet. It is fundamental to the biochemistry of all living organisms. The planet's ecosystems are linked and maintained by water, and it drives plant growth, provides a permanent habitat for many species (such as 8,500 species of fish), and is a breeding ground or temporary home for others, including most of the worlds 4,200 species of amphibians and reptiles described so far. Water is also a universal solvent and provides the major pathway for the flow of sediment, nutrients and pollutants. Through erosion, transportation and deposition by rivers, glaciers, and icesheets, water shapes the landscape and through evaporation it drives the energy exchange between land and the atmosphere, thus controlling the Earth's climate.
Apart from a few minor chemical processes, water is neither created nor destroyed, it only moves from place to place and changes in quality. The total amount of water on Earth is 1.4 billion cubic kilometers (km3), but only around 41,000 km3 circulates through the hydrological cycle, the remaining being stored for long periods in the oceans, ice caps and aquifers. Furthermore, the renewal rate provided by rainfall varies around the world. In the Atacama desert in southern Peru it almost never rains, whilst 6,000 millimeters (mm) of rain per year is not uncommon in parts of New Zealand. In any one place rainfall also varies from year to year.
