The Aral Sea Disaster

The Aral Sea stands as one of the monstrous environmental catastrophes of the 20th Century.

Before 1960, it was the world's fourth largest inland sea – behind Asia’s Caspian Sea, North America’s Lake Superior and Africa’s Lake Victoria – with an area of 68,000 km². It had a vibrant fishing industry employing 40,000 people. Today discarded fishing boats lie on the sand 20 kilometers from shore.

In the 1950’s and 60’s Soviet engineers began diverting its two major inflowing rivers to irrigate cotton fields. As a result Uzbekistan has become one of the world’s major cotton producers. But this drawdown had a disastrous result as the sea lost most of the inflow of its source waters. The mighty Aral Sea began shrinking – and shrank steadily until, in 2004 it was only 25% of its original surface area, and by 2007 it had declined to 10% of its original size.

Harvest Providence

This week-end is Canadian Thanksgiving. . .

And this word from Psalm 65 seems like the perfect 'water' text for the occasion

You care for the land
and water it;
you enrich it abundantly.
The streams of God
are filled with water to
provide the people with grain,
You drench its furrows
and level its ridges;
you soften it with showers
and bless its crops.
Psalm 65:9-10

River Director

In many parts of the world, small farmers irrigate their fields or rice paddies by means of small channels which divert water from a reservoir or stream, a pond or well. The farmer opens or shuts sluice gates to direct water where he or she wants it to go. In larger operations, a variety of irrigation systems are used to ensure that the crops that need water, get it when they need it. Farmers meddle with nature to boost the productivity of their fields. A Hebrew proverb draws a parallel between this agricultural practice and the influence of God on the practices of earthly rulers.

The king's heart is in the hand of the LORD;
he directs it like a watercourse wherever he pleases.
