      Grass-fish in China and Northern Vietnam

      China has a long and rich history of integrated fish farming. Written records from the first and second centuries B.C. documented the integration of aquatic plant cultivation and fish farming. Integrated fish systems, using grass and aquatic plants as fish feeds, are commonly found in many parts of China and Northern Vietnam. These systems are particularly predominant in the irrigated lowland areas of the Changjiang, Pearl and Yangtze River basins. Many of these farms are large, communal ones with cooperative or collective farming.
       
      Grass species, which can easily be produced on the farm, can serve as low-cost supplemental feeds for fish. Commonly cultured fish species, which can feed directly or indirectly on grass, include grass, silver, bighead and common carps.  Grass can be grown along pond boundaries and fed directly to fish. Grass species commonly used include rye, Sudan and napier grasses.

      Napier is also a common feed for cows in Vietnam.

       Soil erosion in the Philippines
       
      Present estimates suggest that, of 13 million hectares of alienable land in the Philippines, some 9 million are degraded. This major long-term problem can be overcome only by ensuring that farmers in susceptible areas adopt cropping patterns capable of maintaining, and even improving, the fertility of the soil and also construct and maintain effective physical barriers to soil erosion. In the Philippines, the preferred method of soil erosion control  broadly consists of planting leguminous trees or shrubs (Leucaena leucocephala or Gliricidia sp.), or strong-bodied fodder grasses such as Napier grass, on contours.
