The cost-effectiveness of mass media for agricultural extension in Malawi
1983
Ouvrage disponible sur : http://documents1.worldbank.org/curated/en/999271468770338179/pdf/multi-page.pdf; International audience; This paper reports the results of research concerning the role of massmedia in providing information to Malawian farmers. To set the context, the paper begins with a brief description of the face-to-face information services provided by the agricultural extension system and by the farmer training centers; it then describes in more detail the operations of the Extension Aids Branch (EAB) of the Ministry of Agriculture.

The impact of agricultural extension services
1983
Ouvrage disponible sur : http://documents1.worldbank.org/curated/en/999271468770338179/pdf/multi-page.pdf; International audience; This paper provides a review of the literature on the effectiveness of agricultural extension services worldwide. It shows that evaluators of the internal effectiveness of extension services are generally critical ; they claim that extension services have poor performance, reach only a small proportion of farmers (those who are better off), have wrong objectives, and are of little help to the agricultural sector as a whole. The author argues that this diagnosis may be excessive, that evaluators often have irrelevant evaluation criteria, and that historically the…
Agroecological engineering
2015
Earth has recently entered the new era of the Anthropocene, during which the rise of human activities are impacting for the first time ecosystems and climate on the global scale. Since the 1960s the green revolution has improved food production in quantity using industrially-designed agriculture, which has led to global pollution by pesticides and losses of food quality, biodiversity and soil carbon. As a consequence there is a need to implement agroecological practices in order to produce food safely and in a sustainable way. This virtual issue presents principles and applications of agroecological engineering, exemplified in 19 selected review articles from the journal Agronomy for Sustai…
Indicators of agricultural intensity and intensification: a review of the literature
2015
Since the 1960s, research has dealt with agricultural intensification (AI) as a solution to ensure global food security. Recently, sustainable intensification (SI) has increasingly been used to describe those agricultural and farming systems that ensure adequate ecosystem service provision. Studies differ in terms of the application scales and methodologies, thus we aim to summarize the main findings from the literature on how AI and SI are assessed, from the farm to global levels. Our literature review is based on 7865 papers selected from the Web of Science database and analysed using CorText software. A further selection of 105 relevant papers was used for an in-depth full-text analysis …
