EXAMPLES OF SUSTAINABILITY IN THE WORLD.

KOREA.
South Korea is, in many ways, a model of reforestation for the rest of the world.  When the Korean War ended, half a

century ago, the mountainous country was quite deforested.  Since 1960, under the dedicated direction of President Park

Chung Hee, the South Korean government put into effect a national reforestation effort.  Basing itself on the formation of

rural cooperatives, hundreds of thousands of people mobilized themselves to dig irrigation ditches and create terraces to

help the trees in the arid mountains.  Today, the forests cover 65 percent of the country, an area that comes to

approximately 6 million hectares.  When I drove through South Korea in November of 2000, I found it gratifying to see the

abundance of trees covering the mountains, which a generation ago were naked.

NIGERIA.

In Nigeria, the farmers who encountered a serious drought and the desertification of the 1980s, began, while they were

preparing the land for their crops, to allow some acacia shoots that grew in their fields to emerge.  When those trees

matured, they reduced the wind velocity, and with that, soil erosion.  Acacia, a pulse, fixes enriched nitrogen into the soil

and contributes to increased crop yield.  During the dry season, the leaves and the pods supply forage for livestock.  The

trees also provide the farmers with firewood.  This act of allowing 20-150 shoots per hectare to grow to maturity over

about 3 million hectares has revitalized the agricultural community of Nigeria.
