E 579: Philippines - Second Agrarian Reform Communities Development Project : environmental assessment

Due to the significant lack of environmental data, both baseline and monitoring, the only possible environmental assessment that can be done at this stage is indicative-reflecting typical environmental impacts of similar or equivalent projects. Certain aspects of commonly accepted practices must be carefully considered. Large-scale conversion of ecologically important systems such as mangrove areas, marshlands, and forestlands can bring about significant environmental impacts that may be adverse in the long term. Adoption of appropriate agricultural practices may not be enough to outweigh the negative impacts resulting from such conversion. Among the potential adverse impacts are loss of soil fertility and erosion. Other mitigation measures would include: undertaking construction only during the dry season, immediately re-vegetating areas adjacent to roads, carefully planning cut-and-fill activities, and providing silt traps to allow settling of solid particles in runoffs. To avoid altering the area ' s hydrology, use drainage systems. Other nuisance impacts can be mitigated by scheduling, regular watering, and stockpiling schemes. Monitor water quality for agro-chemical impact because of water diversion; and monitor potential impacts like water logging of soils, soil salinization, soil alkinization and/or acid sulphate soil contamination, depletion of soil macronutrients, leaching of nutrients from the soil, and/or weed proliferation and eutrophication due to water abundance
