• Global water crisis and future food security in an era of climate change (2010, background): “…et al., 1994); reducing machinery, labour and fuel costs (Shankar and Thirtle, 2005); and second-round or multiplier effects on total production and demand for goods and services and resultant welfare impacts as seen in India (Qaim, 2003; Qaim and Zilberman, 2003) and China (Huang et al., 2004).”
• Impact of Bt cotton on pesticide poisoning in smallholder agriculture: A panel data analysis (2011, result): “This pattern suggests that the largest Bt-related reductions occur in the most toxic pesticides, which is consistent with previous studies in India and elsewhere (Qaim and de Janvry, 2005; Qaim and Zilberman, 2003).”
• Impact of Bt cotton adoption on pesticide use by smallholders: A 2-year survey in Makhatini Flats (South Africa) (2006, result): “Similar effects have been observed under small-scale farming conditions in China and especially in India (Pray et al., 2002; Quaim and Zilberman, 2003; Morse et al., 2004).”
• EU Food Safety Standards, Pesticide Use and Farm‐level Productivity: The Case of High‐value Crops in Kenya (2009, positive): “Following the work of Lichtenberg and Zilberman (1986), Ajayi (2000), Huang et al. (2002), Qaim (2003), Qaim and Zilbermann (2003), Pemsl (2006) and Shankar and Thirtle (2005), this study takes the ‘damage control’ approach to establishing pesticide productivity and computing economic optima for…”
• Modern Biotechnology as an Integral Supplement to Conventional Plant Breeding: The Prospects and Challenges (2006, background): “Pest-resistant genetically modified crops can and are contributing to increased yields and agricultural growth in many developing countries and benefiting small-scale farmers (Qaim and Zilberman, 2003).”
• On the Structural Transformation of Rural Africa (2017, background): “And evidence from South Asia shows that small farmers whose financial liquidity constraints otherwise limit their ability to apply agro-chemicals especially benefit from yield increases arising from GM crops (Qaim and Zilberman 2003; Qaim 2015). b.”
• Economic Impact of Genetically Modified Cotton in India (2004, result): “…Ismael, & Morse, 2003; Ismael, Bennett, & Morse, 2002), Argentina (Qaim & De Janvry, 2002), Mexico (Traxler, Godoy-Avilla, Falck-Zepeda, & EspinozaArellano, 2001), Indonesia (Manwan & Subagyo, 2002), China (Pray, Rozelle, Huang, & Wang, 2002), and India (Naik, 2001; Qaim & Zilberman, 2003).”
• Bt-cotton and secondary pests (2008, background): “The planting of Bt-cotton also resulted in large a reductions in pesticide use in other countries, for example, 39% in India (Qaim and Zilberman, 2003), 47% in Argentina (Qaim and deJanvry, 2003), 77% in Mexico (Traxler et al.”
• Genetic Transformation of Crops for Insect Resistance: Potential and Limitations (2004, background): “On-farm trials carried out with Bt cotton in different states of India have shown that the technology substantially reduces pest damage and increases cottonseed yield (Qaim and Zilberman, 2003).”
• Field versus Farm in Warangal: Bt Cotton, Higher Yields, and Larger Questions (2011, methodology): “…by the fact that several of the studies showing superior field performance by Bt cotton were sponsored by Monsanto (Sheridan, 2009), used data collected by Monsanto's partner, Mahyco (Bennett et al., 2006; Qaim & Zilberman, 2003), or were authored by employees of Mahyco (Barwale et al., 2004).”
• A Meta Analysis on Farm-Level Costs and Benefits of GM Crops (2011, neutral): “Also Qaim and Zilberman [20] show that yield effects of Bt cotton adoption in Argentina are higher than in other countries primarily because of the low level of insecticide use in conventional cotton production.”
• Mode of action of Bacillus thuringiensis Cry and Cyt toxins and their potential for insect control. (2007, background): “The use of insect resistant crops has diminished considerably the use of chemical pesticides in areas where these transgenic crops are planted (Qaim and Zilberman, 2003).”
