This chapter discusses the traditional tillage implement and the alternative tillage implements using animal power in Vertisol management. Among the topics of discussion are land shaping equipment; the ridge and furrow system; minimum tillage with BBM attachments; animal drawn scoops; pond excava...

Diffussion and adoption of Vertisols technology package in highland Ethiopia
Presents the concept and procedure followed to develop an appropriate technology to increase productivity on Vertisols (heavy clay soils) in Ethiopia. Describes the Vertisol farming systems in the Ethiopian highlands and discusses the on-farm technology validation process. Examines yields of majo...

Concepts and procedures for the Development of improved Vertisol technology Development in Ethiopia
This paper ilustrates the principle determining cropping systems for Vertisols by reviewing work in the highlands of Ethiopia. The types of cropping systems that can be applicable in the different Vertisol environments are briefly described. These cropping systems include single cropping; multipl...

Development is a human problem aimed at changing humans and their economic, social, and ecological environments. Throughout history, humans have acquired new knowledge to shape their future. As their needs multiplied and became more complex, science and technology processes of systematic inquiry ...

Evolution toward transdisciplinarity in technology and resource management research: The case of a project in Ethiopia
Describes farmers' participatory roles in technology Development and transfer, drawing on experience from on-farm Vertisol technology research in Ethiopia, i.e. constant consultation w. farmers enabled technical refinements and brought attitudinal changes to the technology by using on animal draw...

Farmer participatory roles in technology Development and transfer: A case study from on-farm vertisol technology experience in Ethiopia
Since 1986 the Joint Vertisol Project (JVP) which involved a number of national and international research and Development institutions in Ethiopia gave high priority to developing alternative management practices for increased and sustainable food and feed production in highland vertisols. The J...

Food and feed production strategies for Vertisols in the Ethiopian highlands
The paper first discusses the need for moving from disciplinary to transdisciplinary research in addressing problems of human Development and environmental management. Then the experience of a research project in highland Ethiopia that started with disciplinary research and component technologies...

From component technology to integrated resource management: Evolution toward trandisciplinary research in a project in Ethiopia
Reports a concerted interinstitutional attempt to generalize the use of the available draught animal power for the construction of more effective soil surface drainage. The hypothesis is that the relatively high productive potential of the Ethiopian highland vertisols, particularly in high-rainfa...
