Future keepers of the Loess Plateau |
1. Background
1.1 Introduction

1.1.1 |
As
the First Loess Plateau Watershed Rehabilitation Project ("Loess I") initiated
in 1993 is about to conclude, and encouraged by its success the same four
provinces participating in Loess I, namely, Inner Mongolia, Shanxi, Shaanxi,
and Gansu, negotiate a similar arrangement with the World Bank for the Second
Loess Plateau Watershed Rehabilitation Project ("Loess II"), due to
commence in 1999.
Loess
II is modeled after Loess I both in scope and features with the intention to
extend the benefits achieved in Loess I to a larger segment of the population
who subsists near the poverty level, and to a larger area of erosion-degraded
land. These projects serve both the
purposes of poverty alleviation as well as environmental revitalization.

1.1.2 |
As
shown by rapid increase in farmer's income and noticeable decrease in the
region's water and soil loss, significant benefits had been achieved in Loess I
almost as soon as the project was implemented, fully justifying the initial
appraisal that the area has high potential for development. Old mud huts and cave dwellings, shown
in (1.1.1), are giving way to new
brick houses, shown in (1.1.2). These scenes are common in Loess I
project areas in
The enthusiastic response of the farmers to project activities is most encouraging. Their trust for the success of th
