- att editors: the following is the second in a four part series of
- features on forests across the world looking at their economic and
- environmental importance to the developed and developing world.
- the first was moved from london earlier wednesday, while the other
- two will be transmitted on thursday.
-
- london, nov 04 (ips) -- blaenavon in south wales must be one of
- the most desolate landscapes in the world. what was once a
- thriving open cast coalmining area is now a windswept, grey-black
- lunar desert, dotted with sparse and patchy grassland.
-
- it is here, in one of britain's most depressed areas, that a
- reclamation experiment inspired by the himalayas and executed by
- bulgarian foresters is using trees to achieve what bulldozers and
- expensive inputs of top-soil have failed.
-
- ''we are trying to create a change in thinking -- that
- reclamation should start from the perspective of ecology rather
- than engineering'', said project leader martin haigh.
-
- a specialist in soil erosion at oxford polytechnic, haigh was
- born just down the valley from blaenavon and has been studying the
- region for 21 years -- the world's longest-running soil erosion
- study on surface coal mining.
-
- haigh believes that shale tips are still unreclaimed 40 years
- after closure because the wrong methods have been employed. the
- standard approach is to fill up the craters, tipping back all the
- shale and trimmings that were taken out, and then spread a layer
- of top-soil over the top.
-
- ''it is literally like putting a carpet over dead land'', said
- haigh, ''eventually, it wears out''. unlike many similar badlands,
- the problem is not toxicity, but the fact that the top soil
- gradually becomes so compacted that nothing will grow.
-
- when the pits are refilled, rocks which have previously been
- underground are left on the surface. not having been exposed to
- the elements before, they break up -- rocks crumble and fall
- apart.
-
- at the same time, the fine clay particles in the top soil get
- washed down, filling the holes in the crumbling rocks. after a
- while nothing can get in -- neither air nor the root hairs of
- incipient vegetation. ''you get a situation where ecology is
- regressing'', said haigh.(more/ips)

-
- in 1978, haigh went on a u.s. scholarship to the dehyradun
- region of the himalayas. ''the scale of erosion there dwarfed
- everything i have ever seen'', he said, ''huge boulders just
- showered down the deforested slopes''.
-
- the idea of team leader s.b. bartarya was to create 'spring
- sanctuaries', leaving the top of hills forested in order to keep
- soil in place, store water and keeping springs running.
-
- it was the himalayan experience, together with the example of
- the chipco activists in india who embraced trees to save them from
- loggers, that convinced haigh he would have to do more than study
- the blaenavon region -- he would have to do something about it.
-
- ''there i was'', he said, ''a so-called foreign expert, brought
- in to advise, yet i was learning from them and back home serious
- problems were going unresolved.''
-
- the last piece in the equation turned up in 1987 during a
- british council-sponsored visit to examine bulgarian land
- restoration projects.
-
- at pernik, a run-down mining region in western bulgaria, haigh
- found what he had been looking for: ''a group which had been
- working very quietly for years -- because bulgaria never had money
- for topsoil, the problem had been handed over to the foresters.''
-
- after 15 years of intense tree planting, they had achieved
- ''some good healthy land reclamation''. one species in particular,
- the false acacia, or robinia pseudoacacia, had proved extremely
- successful at regenerating soil life.
-
- but back in england, haigh's proposal to adapt bulgarian
- methods to wales was rejected by two key parties, british coal and
- the welsh development agency. bearing in mind the ghandian
- ''sarvodaya'' concept of development through community, he turned
- to the voluntary sector.
-
- the charity earthwatch came up with teams of volunteers, svetla
- gentchevba, head of the ecology department at the higher institute
- of forest engineering in sofia, agreed to supervise and a local
- farmer provided a small plot.
-
- the first trees, planted in 1990, are already providing a
- tenuous cover, relieving the bleakness of the terrain. a second,
- far larger area, was planted in the winter of 1991/1992.
-
- rather than the bulgarian acacia, the team opted for native
- species, planted far more intensively than in normal forestation.
- those planted in deeper holes filled with leaf mould have
- performed better than those put in with less support.
-
- ''the principal is universal, whether the region is tropical or
- temperate'', says haigh, ''we are now talking to people in india
- and in the black triangle of czechoslovakia about starting similar
- projects.'' (end/ips/en/ma/mf/92)
