“…Many technology adoption studies emerging in crop sub-sector revealed that the gain from adoption is not satisfactory compared to the expectations, and hence further interventions on factors impeding these are suggested (Kotu et al, 2000;Dixon et al, 2006;Dercon and Christiaensen, 2011;Asfaw et al, 2012;Shiferaw et al, 2014;Ahmed, 2015;Jaleta et al, 2016;Yigezu et al, 2015;Beshir, 2016;Hagos, 2016;Seymour et al, 2016).…”

A study was conducted to analyze factors influencing adoption of wheat technology packages by smallholder farmers in Gurawa, Meta and Habro districts in eastern Ethiopia. The analysis was based on a household survey data collected from 136 randomly selected households. A Two-limit Tobit model was used to elucidate factors affecting adoption of technology packages measured based on an index derived from five components of wheat technologies which included row planting, pesticide application, use of improved varieties, and application of inorganic fertilizers, namely, Diammonium Phosphate (DAP) and Urea. Among the variables included in the model, variation in district, gender, age of the household head, education status of the household head, farm size, distance to market, distance to FTC (Farmers' Training Centers), cooperative membership, dependency ratio, and annual income of the households were found to significantly affect the adoption of wheat technology packages. Policy makers, planners and development practitioners should give due attention to these determinants to support smallholder farmers in wheat production and enhance gains derived from it.

“…Some research demonstrated no investment bias toward favoured areas (Byerlee and Morris 1993) while other research identified a bias that was justifiable on both income and equity grounds (Renkow 1993). Dixon et al (2006) pointed out that while the largest share of benefits derived from wheat breeding from 1960 to 1990 accrued to farmers in irrigated areas, roughly one half of the world's population that is living in poverty is located in the irrigated areas of South Asia.…”

“…However, some estimates suggest that growth rates in yield have been faster over some periods in drier or more heat-stressed environments than in irrigated and rain-fed production systems (Dixon et al 2006;Heisey et al 2002). Lantican et al (2003) concluded that initial gains came from crossover of varieties from favourable environments, but targeted breeding efforts contributed significantly to more recent productivity growth in marginal environments, estimated to be twice that experienced in favourable environments from 1979.…”

“…There has also been growing evidence of saline and waterlogged soils in irrigated areas, falling water tables and a scarcity of fresh water (Byerlee 1996;Pingali and Rosegrant 2001;Shiferaw et al 2008). Dixon et al (2006) provided a concise summary of some of the evidence regarding the determinants of adoption of improved wheat varieties, based largely on CIMMYT's research. First, they pointed out that countries in the developed world reach full adoption of a new variety several times more quickly than countries in the developing world.…”

Crops that feed the world 10. Past successes and future challenges to the role played by wheat in global food security

et al. 2013

Wheat is fundamental to human civilization and has played an outstanding role in feeding a hungry world and improving global food security. The crop contributes about 20 % of the total dietary calories and proteins worldwide. Food demand in the developing regions is growing by 1 % annually and varies from 170 kg in Central Asia to 27 kg in East and South Africa. The developing regions (including China and Central Asia) account for roughly 53 % of the total harvested area and 50 % of the production. Unprecedented productivity growth from the Green Revolution (GR) since the 1960s dramatically transformed world wheat production, benefitting both producers and consumers through low production costs and low food prices. Modern wheat varieties were adopted more rapidly than any other technological innovation in the history of agriculture, recently reaching about 90 % of the area in developing regions. One of the key challenges today is to replace these varieties with new ones for better sustainability. While the GR "spared" essential ecosystems from conversion to agriculture, it also generated its own environmental problems. Also productivity increase is now slow or static. Achieving the productivity gains needed to ensure food security will therefore require more than a repeat performance of the GR of the past. Future demand will need to be achieved through sustainable intensification that combines better crop resistance to diseases and pests, adaptation to warmer climates, and reduced use of water, fertilizer, labor and fuel. Meeting these challenges will require concerted efforts in research and innovation to develop and deploy viable solutions. Substantive investment will be required to realize sustainable productivity growth through better technologies and policy and institutional innovations that facilitate farmer adoption and adaptation. The enduring lessons from the GR and the recent efforts for sustainable intensification of cereal systems in South Asia and other regions provide useful insights for the future.

“…Since the beginning of the international program in the 1960s, over 2000 new wheat varieties have been released in the developing world with an increasing trend over time (Dixon et al 2006). A growing share of these varieties has been derived from crosses made at CIMMYT and selected by collaborators.…”

Abstract:International agricultural research has historically been an example par excellence of an open source approach to biological research. Beginning in the 1950s and especially in the 1960s, a looming global food crisis led to the development of a group of international agricultural research centers with a specific mandate to foster international exchange and crop improvement relevant to many countries. This formalization of a global biological commons in genetic resources was implemented through an elaborate system of international nurseries with a breeding hub, free sharing of germplasm, collaboration in information collection, the development of human resources, and an international collaborative network. This paper traces the history of the international wheat program with particular attention to how this truly open source system operated in practice and the impacts that it had on world poverty and hunger. The paper also highlights the challenges of maintaining and evolving such a system over the long term, both in terms of financing, as well the changing 'rules of the game' resulting from international agreements on intellectual property rights and biodiversity. Yet the open source approach is just as relevant today, as witnessed by the recent global food crisis and looming crop diseases problem of global significance.
