Abstract
Two stratified random sample surveys were conducted to characterise bamboo distribution in the homegardens in Kerala and to examine the nature of interrelationships between bamboo occurrence (abundance) and the size of operational holdings. Methods included a species inventory of the homegardens, besides semi-structured interviews to elucidate the indigenous ecological knowledge on bamboo cultivation. Three hypotheses were tested: (1) the larger operational holdings have a higher frequency of bamboo occurrence, (2) homestead bamboo represents a shrinking resource base, and (3) that the indigenous ecological knowledge on bamboo cultivation is adequate.
Results show that only 3% of the 584 operational holdings surveyed had bamboo, the predominant species being Bambusa arundinacea. Larger holdings and midlands were characterised by a greater abundance of bamboos. Commercialization of the homegarden system, fragmentation of holdings, construction activities, etc., may lead to a substantial obliteration of the state’s rural bamboo resources. Inter-specific competition, allelopathic influences, enhanced rodent population under bamboo cover and the general afflictions to carry out farm operations in the presence of bamboo clumps have created a general apathy towards bamboo. Boundary planting, trenching around the clumps and shade regulation may represent the ecologically rational local practices in vogue.
