Intensification or extensification? Factors affecting technology use in peri-urban lowlands along an agro-ecological gradient in West Africa
The paper analyses whether the increased use of lowlands in proximity to urban centres in West Africa is associated with technological intensification or extensification. Technologies are typified in terms of their orientation ...
The farming systems of the Texizapan watershed, Sierra de Santa Marta, Veracruz, Mexico
(CIMMYT *PSSM, 1998)
The main farming systems of the Texizapan watershed in southern Veracruz, Mexico (200-1,640 meters above sea level) were characterized through a formal survey in 1995. Farm-level data included an inventory of resources ...
Impact of zero tillage in India's rice-wheat systems
(CIMMYT / RWC, 2007)
Political and economic features of the maize seed industry in southern Africa
The seed industry in southern Africa (Angola, Malawi, Mozambique, Zambia and Zimbabwe) has three important features: first, dominance of the government as buyer and distributor of seed; second, a high market share and power ...
Zero tillage impacts in India's rice-wheat systems: A review
To date, the most widely adopted resource conserving technology in the Indo-Gangetic Plains (IGP) of South Asia has been zero-tillage (ZT) wheat after rice, particularly in India. The paper reviews and synthesizes the ...
Specification effects in zero tillage survey data in South Asia's rice-wheat systems
Specification effects in terms of how technology options are contrasted can introduce bias in impact assessment. In a companion paper we evaluated the on-farm impacts of zero tillage (ZT) wheat as a resource-conserving ...
The evolving maize sector in Asia: Challenges and opportunities
Asia's maize (Zea mays L.) sector has shown rapid growth during the last few decades. This article reviews the evolving maize sector in Asia, focusing on the eight main maize-producing countries: China, India, Indonesia, ...
Crop-livestock interactions along agro-ecological gradients: A meso-level analysis in the Indo-Gangetic Plains, India
Although conceptually simple and often idealized, disentangling crop-livestock interactions typically proves more complex in practice. Part of the complexity arises from their changing nature along agricultural intensification ...
