Context <strong>and</strong> Need 9st<strong>and</strong>ards for ERA. <strong>The</strong> third major topic is on <strong>the</strong> <strong>assessment</strong> <strong>of</strong> <strong>environmental</strong> <strong>risk</strong>s. This is divided into three major <strong>the</strong>mes:gene flow <strong>and</strong> its consequences, affects on biological diversity, <strong>and</strong> <strong>the</strong> <strong>risk</strong> <strong>of</strong> resistance evolving in brinjal fruit <strong>and</strong> stem borer(BFSB) to <strong>Bt</strong> brinjal. Although <strong>the</strong>re is no perfectly good division <strong>of</strong> <strong>environmental</strong> <strong>risk</strong>s, <strong>the</strong> first addresses <strong>risk</strong>s that areassociated with genetics <strong>and</strong> evolution <strong>of</strong> plants, including brinjal <strong>and</strong> its wild relatives. <strong>The</strong> second addresses <strong>risk</strong>s that areecologically mediated <strong>and</strong> do not require distinction <strong>and</strong> analysis <strong>of</strong> <strong>the</strong> genotypes within species. <strong>The</strong> third focuses on <strong>risk</strong>sassociated with <strong>the</strong> genetics <strong>and</strong> evolution <strong>of</strong> non-plant species, in particular, <strong>the</strong> target pest, BFSB. <strong>The</strong> report concludes witha section on socioeconomic analysis <strong>of</strong> <strong>Bt</strong> brinjal in <strong>the</strong> context <strong>of</strong> pest control alternatives now available in India. This sectionalso summarises <strong>the</strong> kinds <strong>of</strong> studies that are needed to provide an adequate <strong>assessment</strong> <strong>of</strong> <strong>environmental</strong> concerns that cover arealistic <strong>and</strong> significant <strong>scope</strong> for ERA.Finding 1. <strong>Brinjal</strong> is one <strong>of</strong> <strong>the</strong> most important vegetable crops in India, especially for <strong>the</strong> rural <strong>and</strong> urban poor.Most is grown in <strong>the</strong> three eastern states <strong>of</strong> West Bengal, Orissa <strong>and</strong> Bihar by small-scale resource-poor farmers.After potato, <strong>and</strong> perhaps onion, brinjal is <strong>the</strong> most important vegetable crop produced <strong>and</strong> consumed in India. About 9.5million tonnes <strong>of</strong> brinjal is produced in a year, nearly all <strong>of</strong> which is internally consumed (APEDA 2009). Only 0.04% <strong>of</strong> <strong>the</strong>brinjal produced is exported, mainly to <strong>the</strong> UK, France <strong>and</strong> Saudi Arabia. During <strong>the</strong> hot <strong>and</strong> rainy season, brinjal is one <strong>of</strong><strong>the</strong> few vegetables that can be afforded by <strong>the</strong> rural <strong>and</strong> urban poor (Dr. Prabhakar, IIHR, personal communication).India <strong>and</strong> China are <strong>the</strong> largest producers <strong>of</strong> brinjal by far. Toge<strong>the</strong>r <strong>the</strong>se two countries produce about 2/3rds <strong>of</strong> <strong>the</strong>world’s brinjal, with India slightly behind China. Projected population growth in India suggests that <strong>the</strong> dem<strong>and</strong> for brinjal willincrease in <strong>the</strong> short term.Nearly all brinjal farmers in India are small-scale resource-poor farmers, who farm 0.4ha <strong>of</strong> brinjal <strong>and</strong> purchase many <strong>of</strong> <strong>the</strong>ir farm inputs (APEDA 2009). <strong>The</strong>y comprise less than 10% <strong>of</strong> <strong>the</strong> totalbrinjal growers <strong>and</strong> <strong>of</strong>ten sell to <strong>the</strong> large urban markets. This simple structural breakdown <strong>of</strong> brinjal farmers is critical forunderst<strong>and</strong>ing <strong>the</strong> potential value <strong>of</strong> <strong>Bt</strong> brinjal, as will be discussed in considerable depth in this report.Within India, about 61% <strong>of</strong> <strong>the</strong> brinjal is grown in <strong>the</strong> three eastern states <strong>of</strong> West Bengal, Orissa, <strong>and</strong> Bihar (APEDA2009). Additional production occurs in Assam, Meghalaya, Jharkh<strong>and</strong> <strong>and</strong> <strong>the</strong> o<strong>the</strong>r small eastern states. This area receivesheavy monsoons <strong>and</strong> brinjal can be cultivated around <strong>the</strong> year because <strong>the</strong>re is sufficient water even during <strong>the</strong> “drier” seasons.A larger proportion <strong>of</strong> <strong>the</strong> farmers in this region are small-scale resource-poor farmers than elsewhere in <strong>the</strong> country.<strong>The</strong> remaining ~36% <strong>of</strong> <strong>the</strong> brinjal is produced throughout <strong>the</strong> rest <strong>of</strong> India, with <strong>the</strong> largest concentration in Gujarat.Smaller, but still significant quantities are produced in Andhra Pradesh, Maharashtra, Karnataka, Chhattisgarh, <strong>and</strong> MadhyaPradesh. Overall, <strong>the</strong>re are proportionately more large-scale producers in <strong>the</strong>se parts <strong>of</strong> India, but <strong>the</strong>se tend to be located inperi-urban areas (<strong>the</strong> areas surrounding <strong>the</strong> large cities).Finding 2. India is <strong>the</strong> centre <strong>of</strong> <strong>the</strong> world’s biological diversity in brinjal with over 2500 varieties grown in <strong>the</strong>country. Some local varieties have significant religious <strong>and</strong> cultural value.<strong>Brinjal</strong> is open-pollinated with 12 pairs <strong>of</strong> chromosomes (Doganlar et al. 2002) with scientific name Solanum melongenaL. in subgenus Leptostemonum in <strong>the</strong> large, mostly tropical Solanaceae. <strong>The</strong> National <strong>Brinjal</strong> Germplasm Bank holds nearly3555 <strong>and</strong> 784 wild species, <strong>and</strong> more than 2500 different varieties <strong>of</strong> brinjal have been identified in India (National Bureau <strong>of</strong>Plant Genetic Resources, New Delhi; Sharma SK <strong>and</strong> P<strong>and</strong>ey S, 2009). <strong>The</strong>re is probably additional varietal variation in Indiathat has not yet been identified. India has released ~200 modern brinjal varieties, including 54 hybrids, some <strong>of</strong> which arecommonly grown in India (IIHR 2007, 2008). <strong>The</strong>se facts provide a substantive context for <strong>the</strong> <strong>assessment</strong> <strong>of</strong> gene flow <strong>risk</strong>s,addressed below.Each local region within a state, typically has a characteristic variety that is most commonly grown in <strong>the</strong> region, but notcommonly grown elsewhere (V. Ramprasad, personal communication). Some <strong>of</strong> <strong>the</strong> locally recognised varieties are beingregistered as “Geographical Indicators” under <strong>the</strong> TRIPS Agreement. For example, in Karnataka four varieties includingHirangere, a >10cm, oblong, yellow-greenish brinjal grown around Mysore, <strong>and</strong> Kudochi <strong>and</strong> Malapur in Nor<strong>the</strong>rn Karnataka
