(review of first three issues):
The first issue of Biodiversity
was published in January 2000, the second in May, and the third in
August. The final issue in the first volume will be published in
November and is well under way. To the present time,
Biodiversity has contributed information in the following
areas: agricultural practices in relation to the integrity of
biodiversity and environment; efforts in conservation of forest
ecosystems, and understanding of selected life forms regarding
their life history, state of being, and their functions,
usefulness as food or medicinal sources (Coffee, Pineapple,
Seahorses, Spiders, Whale Shark, Hamilton's Frog...):
1.
January 2000 - Biodiversity 1(1):
In developing and developed countries,
small-scale farmers and peasants have fed much of the world for
numberless centuries. They have used traditional varieties which
undergo continuing selection and are adapted to the type of land
and local climate, soils, drought cycles, etc. The diversity of
these varieties helps protect them against diseases and pests.
They are free to replant their own seeds and exchange them with
their neighbours without charge. This system is sustainable - or
they would not be there. They used local organic fertilizers and
biological approaches to pest control. So the off-site impact of
this kind of farming on human and wildlife health was minimal.
This is not to paint a picture of a dream-like perfection. There
were problems, but these could often be met by due attention of
working together with their neighbours and their governments and
their agencies.

These farmers are now being squeezed off the land by powerful
economic forces in favour of industrial style farming. Crops are
now patented or consist of hybrid varieties so that the resultant
seeds cannot be replanted. The varieties have costly fertilizer
inputs beyond the reach of most small farmers. Pesticides either
have to be sprayed on them (and they may be genetically adapted to
a single pesticide brand) or are built into them. The varieties
are used over large areas of landscapes. This means that this
paradigm is not sustainable in the long run, is harmful to human
and wildlife health, is costly, and is not affordable by the
small-scale farmer. Moreover, the seeds and pesticides are the
purview of transnational corporations, meaning profit is siphoned
out of the country.
The first issue of Biodiversity devoted itself to
discussing these issues and offering alternatives as well as
featuring both an article on the threats of genetic engineering to
biodiversity and a contrasting opinion piece favouring genetic
engineering. It also provided the example of how one woman farmer
in Mexico, and her friends, cultivated diverse crops to feed their
families.
2. May 2000 - Biodiversity 1(2):
The second issue discussed the
diversity of spiders and their utility as biocontrol agents.
Exploration of this diverse group was undertaken to counterbalance
the usual negative image that spiders have and to show their
ecological roles in natural environments and agroscapes.
Parks are sometimes seen by development agencies and some policy
makers in developing countries as extras which benefit only
visitors from the First World. The article on Non-Damaging
Biodevelopment in Costa Rica shows how such protected areas can be
managed for the benefit of and with the participation of local
people, as well as others, and discusses some of the financial and
other difficulties tha t may be
encountered. It also showed how administration can be made more
effective by combining government agencies involved in protection
under one agency.
A portion of the people around the world live too distant from the
power grid to be able to tap into it. An example from rural
Ontario shows how it is possible to draw upon the benefits of
electricity without being connected to the grid.
The article on Seahorses describes the importance of taxonomic
knowledge to the management and conservation of these peculiar and
endangered fishes.
3. August 2000 - Biodiversity 1(3):
The third issue
told about the achievement of social forestry in India. This is
one of series of articles which will, we hope, reverse the
dominantly one-way stream of information from developed to
developing countries as well as facilitate lines of communication
between developing countries.
An
article on Mexican tropical dry forests shows this type of forest
is much less extensive and less varied biologically than rain
forest but with a rich flora which provides firewood, food,
medicines and other valuable products. Tropical dry forest is
being rapidly reduced in Mexico and elsewhere. Conservation effort
in Mexico shows that, with careful management, much of the origin
a l vegetation, including 28 food-producing trees, shrubs and
vines can be restored using only organic farming methods. This
approach of farming shows a five fold increment of income as
compared with corn cultivation alone. A series of recommendations
to further these methods are given. They are designed to help
reduce the dependency on cash crops, raise living standards,
restore in part the original forests, reduce erosion, and preserve
much of the original flora from which new food crops and medicines
ma y be derived.
A review of a critically endangered life form, Hamilton's Frog, (Leiopelma
hamiltoni), shows an interesting aspect of life of a
primitive Frog, a Frog which has a short tail and no web between
their toes. Frogs of the genus Leiopelma resemble those
found in the Jurassic era. Approximately only 200 frogs remain
distributed in a small area in New Zealand. Habitat destruction is
probably responsible for the restricted distribution of this Frog.
An article on the Whale Shark, the largest living fish is
presented; shows this Shark species is rare but is worldwide in
tropical and subtropical areas. Details are given of 20 sightings
in 50 years in Venezuelan waters. Records may be correlated with
increased marine productivity.
