En esta sección se retrata como se hace y vive la agroecología en un contexto campesino rural. Desde una comunidad en las Lomas del Escambray (prov. Villa Clara) se intenta transmitir el corazón y la energía de la agroecología en Cuba, a la vez que mostrar el funcionamiento del MACAC, las prácticas cotidianas y las reflexiones de los/as protagonistas.
Cette partie a pour objectif de retracer l’histoire de la création de l’agroécologie et de comprendre les conditions qui lui permettent d’exister dans un contexte paysan rural. Depuis ces mêmes fermes, les protagonistes essayent de transmettre le sentiment et le cœur de l’agroécologie tout en laissant voir le fonctionnement du MACAC, les pratiques quotidiennes et les réflexions de chaque protagoniste.
This section intends to picture how is agroecology done and lived in a rural peasant context. From their own plantations they try to carry over the feeling and heart of agroecology, while showing the operation of PTPAM at the same time, the everyday practices and the thoughts of their main players.
This study examines the price transmission mechanisms in the Bloemfontein beef market using the producer price and retail prices at four retail outlets collected over a period of 3 years. It further estimates the causality links between the producer and retail prices. The traditional (Engle-Granger) and standardized (Enders & Siklos) Augmented Dickey- Fuller procedures were used to test for co-integration and asymmetry in price transmission

levels was constructed based on multivariate techniques, according to the adoption of seven technologies. The main objective of the study was to relate SR and innovative behavior to the technology clusters
The aim of the paper is to evaluate the impact of value-webs as an innovation in agricultural production on welfare of cassava smallholders in Nigeria. The estimation procedure involved the alternative process of multivalued treatment models when treatment units have multiple values. The study thus extends previous impact studies which focused on estimating causal effects from binary treatment units. The treatment units were determined from the extent of utilization of cassava which informed the classification of households into value-web groups.
The study analyzed the value chain of natural rubber in Nigeria.
