Hi,

This may not be a bad time to introduce myself since I recently joined the 
list.

25 years ago I was a research biologist in Belgium. There were several 
reasons to look to do something else at the time and we bought a 70 acre 
farm in SW Ireland where we have been into organic self sufficiency farming 
ever since. Especially the first few years were hard for we had three young 
children to rear with no money left and also as we discovered hardly any 
soil at all. We brought some crops with us and none of these survived even 
the first month here.

So I spend a good bit of time trialing out crops that could stand up to our 
harsh conditions. Many of the most successful happen to be old Inca crops. 
Quinoa produces about 3 times as much as wheat here for instance. Yacon 
(Polymnia sonchifolia) does extremely well as do potatoes, machua, achocha 
and a few others.
Amaranth needs a bit more heath than we have here usually but it did quite 
well with the protection of a poly tunnel last year. This year we have had 
the coolest summer in maybe a century and the amaranth is less than 10 % of 
the usual. This will maybe allow us to eventually breed a cool resistant 
variety by making use of the best seeds for a while.

John

> Smithsonian.com, September 07, 2011,
>
> Inspired by recent archaeological research, the people in the Cuzco
> region of Peru are rebuilding terraces and irrigation systems and
> reclaiming traditional crops and methods of planting.
>
> The Andes are some of the tallest, starkest mountains in the world. Yet
> the Incas, and the civilizations before them, coaxed harvests from the
> Andes' sharp slopes and intermittent waterways. They developed resilient
> breeds of crops such as potatoes, quinoa and corn. They built cisterns
> and irrigation canals that snaked and angled down and around the
> mountains. And they cut terraces into the hillsides, progressively
> steeper, from the valleys up the slopes. At the Incan civilization's
> height in the 1400s, the system of terraces covered about a million
> hectares throughout Peru and fed the vast empire.
>
> Over the centuries, cisterns fell into disrepair, canal beds dried up
> and terraces were abandoned. This process began when the Spanish imposed
> their own crops and forced people off traditional lands to farm and mine
> for the conquistadors. The local populations were devastated by war and,
> more significantly, by disease. Some researchers estimate that as many
> as half of the Incan population died soon after the Spanish conquest.
> Much of the traditional farming knowledge and engineering expertise was
> lost.
>
> The ghost of the Incas' farming achievements still shadows the Andes.
> The remnants of ancient terraces appear as lines of green on the
> mountains. Former irrigation canals carve hollows into the land. Today,
> in a corner of the Andes, people are breathing new life into ancient
> practices. Inspired by recent archaeological research, they are
> rebuilding terraces and irrigation systems and reclaiming traditional
> crops and methods of planting. They do this in part because Incan
> agricultural techniques are more productive and more efficient in terms
> of water use. But these modern farmers also believe the Incan ways can
> offer simple solutions to help protect communities' food supply in the
> face of climate change.
>
> Archaeologist Ann Kendall began studying terraces in the Cuzco region of
> Peru in 1968. She intended to focus on Incan architecture and stonework,
> but she was soon captivated by the dry canal beds and terraces that
> beckoned from across the valley. I thought about the problem that local
> people had no water and didn't cultivate this [agricultural system], she
> says. She remembers thinking, if only one could study traditional
> technology and rehabilitate all this in the Andes, wouldn't it be 
> wonderful.
>
> She decided to study the development and technology of the Incan
> agricultural systems with the idea of rehabilitating them. Over the
> years, she learned how the Incan builders employed stones of different
> heights, widths and angles to create the best structures and water
> retention and drainage systems, and how they filled the terraces with
> dirt, gravel and sand.
>
> In the 1600s, Garcilaso de la Vega, the child of a conquistador father
> and an Incan noblewoman, described the Incan terracing system in The
> Royal Commentaries of the Incas: In this way the whole hill was
> gradually brought under cultivation, the platforms being flattened out
> like stairs in a staircase, and all the cultivable and irrigable land
> being put to use.
>
> The terraces leveled the planting area, but they also had several
> unexpected advantages, Kendall discovered. The stone retaining walls
> heat up during the day and slowly release that heat to the soil as
> temperatures plunge at night, keeping sensitive plant roots warm during
> the sometimes frosty nights and expanding the growing season. And the
> terraces are extremely efficient at conserving scarce water from rain or
> irrigation canals, says Kendall. We've excavated terraces, for example,
> six months after they've been irrigated, and they're still damp inside.
> So if you have drought, they're the best possible mechanism. If the soil
> weren't mixed with gravel, points out Kendall, when it rained the water
> would log inside, and the soil would expand and it would push out the
> wall. Kendall says that the Incan terraces are even today probably the
> most sophisticated in the world, as they build on knowledge developed
> over about 11,000 years of farming in the region.
>
> Over the past three decades, using archaeological details about the
> construction of terraces and irrigation systems, a development charity
> called the Cusichaca Trust, which Kendall formed in 1977, rehabilitated
> and irrigated 160 hectares of terraces and canals in the Patacancha
> Valley, near Cuzco. The project was a success: it improved water access
> and agricultural production, and local families maintain the structures
> today. Lessons from the Patacancha Valley are now being employed to
> restore Incan agricultural systems in other areas of Peru.
>
> The thud of hammer on rock reverberates in a remote valley in the
> Apurímac region. A worker from a nearby village swings a mallet and
> chips off the edges from a massive stone that has been hauled into the
> bed of an ancient irrigation channel. That rock will form one wall of
> the repaired channel. He and a half-dozen workers have been hard at work
> for a month already, and have rebuilt about a third of the channel.
>
> The work is part of a two-year project to mitigate the effects of
> climate change. Kendall and her local partners in Cusichaca Andina (an
> independent Peruvian nonprofit formed in 2003) began activities in the
> remote regions of Apurímac and Ayacucho because they wanted to expand
> past Cusco. The area is blanketed with terraces, most unused for
> centuries. It also was the center of power for the Sendero Luminoso, or
> Shining Path, during the 1980s and early 1990s. Many locals fled from
> the guerrilla fighters, abandoning farms and leaving the area with
> little farming expertise.
>
> The exact age of this particular channel hasn't been determined, but
> Adripino Jayo, the regional director of Cusichaca Andina, which leads
> the restoration with funding from the World Bank, estimates that it's
> been used to funnel water from a nearby spring perhaps since the time of
> the Wari, whose civilization spread over the Andes for hundreds of years
> before the Incan empire.
>
> Trainers from Cusichaca Andina schooled the community on how to repair
> the canal using local materials, which are cheaper than concrete and
> avoid the need to import materials from the city. One worker swings a
> pickax to carve out dirt and then shovels it aside. Another worker lines
> up stones evenly on the channel's sides. They use local clay to fill the
> gaps between boulders and alongside the earthen banks. When it hardens,
> the clay is watertight.
>
> Yellowing stalks of corn, quinoa and amaranth drape over and obscure the
> stone walls that have already been repaired. From September through
> December last year, local workers rehabilitated 54 hectares of terraces.
> By the spring of 2012, the teams hope to rebuild nearly two miles of
> irrigation channels.
>
> In the few restaurants that can be found in nearby villages, rice
> trucked in from cities and the coast is on offer more frequently than
> the local quinoa. Jayo quotes a common city refrain that can keep those
> in the mountains from celebrating their own bounty: only the poor eat
> quinoa. In the latter half of the 1900s, as remote mountain towns gained
> increasing access to radio, television and communication with the
> cities, local crops fell out of favor.
>
> But local grains are more nutritious and better suited to the Andean
> land and climate. So Cusichaca Andina has conducted educational training
> campaigns and given away seeds for quinoa, corn and amaranth. The seeds
> have been planted over 45 hectares, now used as demonstration sites to
> highlight how traditional farming practices of planting corn, quinoa and
> squash together, instead of in individual plots, can yield better
> results, as the crops symbiotically protect and nourish each other.
>
> The organization has also focused on rescuing seeds and varieties that
> have been in danger of disappearing, such as huaña, a bitter potato
> variety that resists hail, frost, droughts and excess rain. After being
> soaked for days and frozen outdoors overnight to remove the bitterness,
> the potato is dried and can be stored for years.
>
> Jayo highlights the strength and resistance of this crop: Now that we're
> facing the crisis of climate change, it's worth recovering crops such as
> these. Clemente Utani, the mayor of the nearby town of Pomacocha,
> focuses on the historic significance of Cusichaca's work, saying, "We're
> recovering what we lost from our ancestors".
>
> Approaches such as these might be crucial for poor Peruvian farmers.
> Glacial melt and the seasonal rains, the key suppliers of water, are
> already affected by climate change. Rains have already shown signs of
> decreasing, temperature swings have become more extreme and Peru's
> glaciers have shrunk about 20 percent since the 1970s.
>
> The need for water conservation and agricultural development far
