Bet Land Management Options (page being improved)
In most instances,
the land management options identified for introduction in the catchments
were variants of the contour hedgerow farming in combination with other
practices like soil fertility management and animal production. In the
Philippines, the use of natural vegetative strips (NVS) is one technology
that was identified by the farmers. This is done by using naturally-growing
grasses and some agro-forestry crops as hedgerows. It is worth noting
that several farmers have already made use of this technique as a result
of the promotion activity by ICRAF in the area. Adoption seems to be affected
by the tenure system of the farmers. About half of the landowners have
adopted some conservation measures but none from the tenants (Duque et
al, 2001). For those who are interested but have not yet adopted, the
major reason is the cost of establishment. In Indonesia, the
option identified is a combination of fodder grass planted on alternate
terraces of land currently used for annual upland crops and cattle fattening.
In terms of seriousness of erosion, this area needs priority attention.
The fodder grass is expected to reduce erosion and serve as feed for the
livestock. The identification of the option was based on lessons learned
from elsewhere in Indonesia that farmers' adoption and improvement of
a conservation measure is determined by the economic contribution of the
measure to the household economy. Farmers are attracted to a practice
only if the practice promises economic benefit and this consideration
must be put forward in the participatory technology selection. Vetiver grass and
T. candida are the hedgerows in the alley cropping system introduced in
the catchment in Vietnam. The technology intervention has just been started
and so the effect of the intervention on crop growth and yield cannot
still be evaluated. Possibly as a result of the demonstration site on
alley cropping near the site, the farmers believe that the system will
reduce runoff and soil loss, add organic matter and improve soil fertility
by adding the hedgerow trimmings. Other options that
the farmers in the Philippines look at are the planting of pasture legumes
during fallow after growing potato, corn or cabbage instead of grass fallow
for 3-4 years and planting tiger grass and bamboo along the creek banks
to serve as buffer. Tiger grass and bamboo are expected to provide additional
income as tiger grass is used for soft broom and bamboo as props for the
banana plantation. It was observed that
presentation and discussion of the results of monitoring in the catchments
with the farmers helped very much in the identification of the land management
options that are more appropriate in the particular area. While the farmers
are aware of soil erosion and its negative effect, actual observations
and the alarming figures presented increased their appreciation of looking
at a longer time horizon. As they are aware of the declining productivity
of their land, they were also interested in fertility management. Of course,
their immediate concern is the benefits that they will gain in the short
term. These concerns should be given more emphasis in introducing any
interventions in their farms.
