Zusammenfassung |
The city of Aksu, situated at the northern fringe of the Taklimakan Desert
in northwest China, is exposed to severe periodic dust and sand storms. In
1986, local authorities decided to establish a peri-urban shelterbelt
plantation, the so-called Kökyar Protection Forest, with the aim of
reducing dust and sand storm impacts on Aksu City by the regulating ecosystem
services provided by the plantation. It was realised as a patchwork of
poplar shelterbelts and orchards. The total area of the plantation reached
3800 ha in 2005. The Kökyar Protection Forest is used as a case study to answer the following question: under which institutional frameworks and to
which financial conditions can peri-urban shelterbelts be established and
maintained? The endeavour of planting the shelterbelt was made possible by
the annual mass mobilisation of Aksu citizens, based on the Chinese
regulation of the "National Compulsory Afforestation Campaigns".
Establishment costs amounted to ca. CNY 60 000 ha−1 (ca. USD 10 000 ha−1).
Permanent maintenance of the plantation is facilitated by
leasing orchard plots to private fruit farmers. From the perspective of the
local economy, annual farming net benefits generated by Kökyar fruit
farmers more than compensate for annual government grants for maintenance,
resulting in an average overall monetary net benefit of at least CNY 10 500 ha−1
(ca. USD 1600 ha−1) in the long term. For a more
complete understanding of Kökyar Protection Forest, future research
should be directed towards quantifying the effect of its regulating
ecosystem services and on investigating the negative downstream
consequences of its water consumption. |
