Due to the increasing extension of areas planted to cassava in tropical countries, the maintenance of biological equilibrium through adequate integrated control techniques becomes imperative as well as the collection of data on var. resistance, biological control, and cultural practices. Basic information for integrated pest control is given. Arthropods attacking cassava are described regarding yield losses, biology, morphology, and ecology. Criteria for the establishment of a control program on var.
The management of cassava intercropping and its evaluation are described. Multiple cropping systems are defined: consecutive cropping and intercropping (mixed intercropping, row intercropping, strip intercropping, and relay intercropping). Basic biological and nutritional aspects of multiple cropping are analyzed and cassava intercropping systems practiced throughout the world (Latin America, Africa, and Asia) are described.
Yield trials with farmers and acceptance surveys were conducted in Colombia in 1969-1970 to assess the potential use of opaque-2 maize in the tropical regons of the country. Yields were variable, particularly from one farm to another. In spite of this variability which may have confused the results, and analysis of variance was applied, using farms as replications.
Despite challenges in many river
basins, overall the planet has
enough water to meet the full range
of peoples’ and ecosystems’ needs
for the foreseeable future, but
equity will only be achieved through
judicious and creative management.
Benefit-Sharing Mechanisms (BSMs) work to redistribute the benefits of a healthy watershed equitably to everyone and to create a virtuous circle between the welfare of people and the ecosystems they live in.
An introductory video to Benefit-Sharing Machanisms. Discover how Benefit-Sharing Mechanisms (BSMs) work to redistribute the costs and benefits of a healthy watershed equitably amongst everyone.
