Benefits, justifications and risks
Environmental status
The project is classified in category “A”
because no significant negative environmental impacts are expected.
In fact, there are likely to be substantial positive environmental
impacts.
Smallholder grown traditional cash crops, coffee
bushes in particular, are sometimes planted in overexploited highly
eroded hillsides. Being a perennial shrub, which requires mulching
among the good husbandry practices, coffee can play a role in soil
conservation, if adequate practices are applied. The poor remuneration
of coffee growers during the 1990s has caused most smallholders
to abandon such good practices. The IFAD project, by providing a
stable and more interesting price to growers will contribute to
re-establishing good crop coffee husbandry, which will help restoring
the potential role of coffee bushes in soil conservation. Similar
considerations apply to tea which are also perennial plants. Perennial
plants have relatively deep and robust root systems which bird the
soil and further enhance soil stability.
The project funded technical assistant services
provided to cash crop growers will include the standard recommendations
of MINAGRI with respect to soil conservation and anti erosion techniques.
The higher farm income, resulting from the project interventions,
and the guaranteed credit scheme, are expected to remove some of
the farmers’ income and cash-related constraints for adopting
such practices.
The project funded feasibility studies of organic
conversion of tea and coffee production will establish the technical
requirements and the financial viability of adopting such practices.
With respect to coffee, in particular, the project funded agricultural
research will emphasise IPM and other means to reduce the use of
chemicals. If proven feasible, organic conversion will significantly
contribute to environmental protection in the tea and coffee growing
areas supported by the project.
Most new cash and export crops developed recently
in Rwanda also contribute to checking soil erosion. For example,
maracuja is a vine, useful for holding the soil where it is planted.
Mulberry trees (silk worm production), and other fruit trees can
be used to check soil movement. Gooseberries are a native plant
in Rwanda, grown on a handkerchief of land, very closely controlled
in the family home garden. In addition, the new cash crops are normally
grown with little of no use of chemical inputs, which not only helps
to develop a market of organic products, but also ensures that incremental
production will not be at the expense of pollution of the Rwanda
farmer’s fields and ground water resources. Eventually, organic
conversion will also be extended to new cash and export crops production,
where feasible.
Significant project induced environmental hazards
are limited to the impact of the effluent of the new coffee washing
stations. This could produce serious damages. The cost estimate
of the washing stations includes the plant required to avoid releasing
any pollution material from the stations. Consultants employed by
the PCU will control that the coffee processing companies comply
with the project policy in this respect.
