In 2006-2009, the author conducted a series of ex-ante impact assessments of Bt eggplant adoption to evaluate potential benefits in terms of improving farmers’ and consumers’ welfare, improving the environment, alleviating poverty of eggplant farmers, and improving nutritional status of consumers. Results of these studies showed big potential of the technology once released and adopted by farmers. In the absence of information on actual field plantings of Bt eggplant, these studies used information on the potential yield levels, benefits, and costs elicited from farmers, scientists and industry experts. This present study provides a thorough socioeconomic analysis of the eggplant production environment where multi-location field trials of Bt eggplant technology were conducted, including the socioeconomic profile of eggplant farmers and farms within the field trial sites. It quantifies the benefits from Bt eggplant technology based on results obtained from multi- location field trials, and analyzes its performance relative to non- Bt eggplant in terms of yields, cost efficiency, net profitability, and other economic parameters. It provides information to support the commercialization of Bt eggplant. It also details the knowledge, awareness, and perception (KAP) of farmers in Pangasinan and Camarines Sur where the field trials were conducted. The conduct of field trials of the eggplant fruit and shoot borer (EFSB)- resistant ( Bt ) eggplant in Luzon was approved by the Bureau of Plant Industry through biosafety permits issued on 15 March 2010. The field trials aimed to generate information on the efficacy, yield, and horticultural performance of promising EFSB-resistant transgenic eggplant lines (Bt eggplant) containing MAHYCO event EE-1 into an open-pollinated variety (OPV). It also aimed to generate local data on non-target arthropods in support of biosafety regulatory approval for propagation and Fertilizer and Pesticide Authority (FPA) registration. Two of the approved trial sites in Luzon include Sta. Maria, Pangasinan and Central Bicol State University for Agriculture (CBSUA) in Pili, Camarines Sur.
