This study deals with te costs and effects of land development projects in The Netherlands. The methods to assess these costs and effects are described and discussed. Effects encompass economic as well as social effects, effects on nature and landscape and on environment.

By means of physical planning the government tries to advance a development aiming at physical conditions as good as possible for society. For this purpose the provincial government has the instrument regional plan, in Dutch streekplan at its disposal. The plan presents the main features of future development in the plan area. Physical planning provides for relatively elaborated preparation and establishment procedures. They are partly statutory laid down, but in practice often completed with various other procedures.

The objectives of the diagnosis of bean production are to (1) contribute criteria for the design and completion of on-farm trials of the new bean technology and (2) to take information to research centers that helps define bean research priorities. A summary is presented of the methodology suggested and practiced in national and international courses on on-farm research carried out by CIAT's bean program.

The main objectives of the cooperative societies of the 1960’s were the promotion, in accordance with cooperative principles and the requirements of social justice, of better living, better business and better methods of production by reducing the cost of credit, etc. Most of the societies then were farmers' cooperatives whose membership were composed of land owners, provincial and district Governors businessmen, etc. The leadership was also controlled by the same people.

This paper focuses on the proposals for food and agriculture development 1986 – 1990. the experiences and implications of the current crisis re-emphasize ever more sharply Africa's development priorities in the immediate future and in the long run.

The results of a case study conducted in Betulia (Sucre, Colombia) in May-Dec. 1983 to evaluate the competition for land between cassava cultivation (monocropped or in association with maize or yam) and cattle raising are discussed. In general, profits from cassava either in association or in monoculture are much higher than for cattle raising. Regarding labor requirements, cassava cultivation and cattle raising are equally attractive from an economic viewpoint.

The results of a survey conducted in 1983 among 416 farmers participating in the integrated rural development project (DRI, Colombia) in Atlantico (60), Bolivar (66), Cordoba (156), and Sucre (134), on land use and importance of cassava within the farming system, are presented. Except for Bolivar, where cassava and yam plantings decreased, increased land use attributable to increased credit availability was observed. In general, 1.7 ha cassava was planted per farm in 1982-83, mainly in association with yam, maize, and plantains; 55 percent of the land planted included cassava.

In the Kinangop Plateau of Kenya where small holder farmers have been settled, varied climate and soils occur and the level of land use and management is not as high as may be expected. The climate and soils were therefore studied with a view to identity the constraints they present to land use and management and how the constraints may be rectified. Low temperatures and frequent frosts are the main climate constraints while imperfect drainage, low fertility and shallow effective rooting depth are some of the soil constraints.

This paper concentrates more on the indicators that deal more or less directly with the increase of agricultural productivity and production. There is the fundamental constraint then that because of the imprecise nature of some of the factors to be measured, the indicators themselves may not in fact be measuring what they were meant to measure. However, this does not relieve the user of constructor of indicators from the obligation to offer a hypothesis as a start and then work to the final “theorem” for that is what all indicators at the start are hypothesis.

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.
