  • However, China’s industry is dependent on non-wood fibers (largely agricultural residues) at a 3:1 ratio over wood fiber. This suggests a concentration of many smaller operations. In fact, China’s rapid agricultural growth since 1978 provided fiber for eight-fold growth in the production of smaller papermills between 1984 and 1992 (CTAPI (1993)). The smaller mills have been rapid innovators, but they remain especially environmentally intrusive. They are dependent on pollution control technologies that are not as effective for non-wood fibers.

  • small water bodies like ponds now contributes 80% of the country’s inland fish production. However, future growth in freshwater aquaculture to meet rising demand for fish is likely to be constrained by limited supplies of land for digging new ponds and of water to fill them. In this context, reservoirs offer immense scope for increasing fish production.
