Concepts and practices in agricultural extension in developing countries: A source book
This source book, a joint effort of ILRI and IFPRI/ISNAR, compiles available and recent literature on developments in the agricultural extension approaches and practice, mainly focusing on developing countries. This will help both practitioners and students of extension to access knowledge regarding various changes in various parts of the world and help learning from these experiences. -
Ethical Code of Conduct for Agricultural Extension and Advisory Services Providers
En 2016, le ministère de l'agriculture, de l'industrie animale et de la pêche, a formulé le programme national de développement agricole.
La politique d'extension (NAEP) qui a été approuvée par le Cabinet le 26 octobre 2016 et lancée le 6 Décembre de la même année. La politique envisage un système de prestation pluraliste avec de multiples fournisseurs.
Pour garantir que le large éventail de prestataires de services de vulgarisation agricole offre un service de qualité aux agriculteurs et autres bénéficiaires, le PNEA prévoyait l'élaboration des lignes directrices, y compris un code de conduite éthique pour guider la conduite des prestataires de l'AEAS dans l'exercice de leurs fonctions, et est considéré comme un code de conduite recommandé, auquel des ajouts ou des modifications peuvent être apportés en tant le besoin s'en fait sentir.

Long-term effect of forest and landscape restoration practices on soil organic carbon stock in semi-arid Burkina Faso
In semi-arid areas, forest and landscape restoration (FLR) practices are being implemented to reverse the land degradation process. The objective of this study was to investigate the long-term effect of FLR practices on soil organic carbon stock (SOCs) under different land uses in the semi-arid region of Burkina Faso. The study was conducted on degraded land under rehabilitation practices for 45, 27, 18 and 11 years, which were compared to similar land without specific rehabilitation measures. The soil was collected in 2018 in 35 sampling plots of 30 m x 30 m. Soil analysis concerned bulk density, soil particle size, soil pH, soil organic carbon content, and respiratory activity of microorganisms. SOCs increased by 150%, 98% and 29% over 0-10 cm depth in 45-, 27- and 11-year of FLR practices, and decreased by 6% in 18-year of FLR practices compared to their respective control. SOCs were not linearly increased with the duration of the implementation of FLR practices because the variation of SOCs depends on several other parameters such as soil texture, and types of combination of FLR practices. The highest SOCs were recorded for 27 years (9.5 t.ha-1) and 45 years (8.5 t.ha-1) of FLR practices. This study revealed the importance of including Assisted Natural Regeneration (ANR) as one of the combined FLR practices, for improvement of SOCs.
