Replication Data for: Mbosso C Degrande A Villamor G van Damme P Tchoundjeu Z Tsafack S 2015 Factors affecting the adoption of agricultural innovation: the case of a Ricinodendron heudelotii kernel extraction machine in southern Cameroo

Charlie Mbossio
This dataset was moved to: https://doi.org/10.34725/DVN/ZZDMXAAgroforestry is now accepted as a sustainable way of improving existing cropping systems. As with other agricultural innovations, the adoption of agroforestry practices depends on farmers’ perceptions of the benefits that would arise from the use of these practices. Ricinodendron heudelotii (Baill. Pierre ex Pax.) or njansang (in Bassa local language) is a tropical tree, the kernels of which are in high demand in Cameroon as a thickening ingredient. Njansang...

Tsafack SAM, Degrande A, Franzel S, Simpson B. 2015. Farmer-to-farmer extension: a survey of lead farmers in Cameroon. ICRAF Working Paper No. 195. Nairobi, World Agroforestry Centre.

Sygnola Tsafack & Degrande Ann
This dataset was moved to: https://doi.org/10.34725/DVN/ZW5I9VThis study examines how the farmer-to-farmer (F2F) extension approach is implemented by farmer trainers in Cameroon. Those farmers selected to lead F2F extension are often known by different names but in this study, we use the term “lead farmer” (LF) as a generic term even though different names sometimes imply different roles. A questionnaire was used to collect data from 160 randomly selected LFs in six regions in Cameroon in...

This dataset was moved to: https://doi.org/10.34725/DVN/ZDW61DThe Building Biocarbon and Rural Development in West Africa Programme aims to demonstrate the multiple developmental and environmental wins that result from a high value biocarbon approach to climate change and variability in large landscapes principally in Mali, Sierra Leone and Guinea. The Programme will also build local institutions and capacity to be able to sustain the benefits in the sites and will establish linkages with related initiatives to jointly...

Sygnola Tsafack and Ann Degrande (2015) The Value of Printed Sources of Information in Agricultural Extension Case Study on “The Farmer’s Voice” in Cameroon, MEAS Evaluative Case Study

Tsafack Sygnola & Degrande Ann
This dataset was moved to: https://doi.org/10.34725/DVN/Z1XF0SVarious methods are used to provide extension workers and farmers with agricultural information. Printed materials remain a major source of information, despite digitalization of information networks, but few studies have looked at their effectiveness. The present work characterizes and assesses the effectiveness of The Farmer’s Voice (TFV), an agricultural newspaper in Cameroon. Data were collected using a semi-structured questionnaire from 107 randomly sampled readers (mainly farmers, lead farmers and extension...

L’objectif général de cette étude est de générer des connaissances sur l’effet de la quantité du combustible et de la saison du feu sur le comportement du feu et les propriétés chimiques et biologiques du sol afin d’aider à la gestion...

Replication Data for: REDD+ Policy Approaches in the Congo Basin: A Comparative Analysis of Cameroon and the Democratic Republic of Congo (DRC)

Fobissie Kalame, Alemagi Dieudonne & Minang Peter
This dataset was moved to: https://doi.org/10.34725/DVN/WK3RANThe Congo Basin forests are a prime location for implementing REDD+. National REDD+ policy processes are ongoing and many REDD+ pilot initiatives are being demonstrated. However, the level of national engagement, progress and distributionof REDD+ activities varies considerably in the different Congo Basin countries. This study therefore uses a set of criteria to assess national and international policy initiatives and approaches for advancing REDD+ implementation in Cameroon and the Democratic...

Replication data for: Plant elemental composition and portable X-ray fluorescence (pXRF) spectroscopy: quantification under different analytical parameters

Erick Towett, Keith Shepherd & B Lee Drake
This dataset was moved to: https://doi.org/10.34725/DVN/WGWE8SEmergence of portable X-ray fluorescence (pXRF) systems presents new opportunities for rapid, low-cost plant analysis, both as a lab system and in situ system. Numerous studies have extolled the virtues of using pXRF for a wide range of plant applications, however, formany such applications, there is need for further assessmentwith regards to analytical parameters for plant analysis. While pXRF is a potential powerful research tool for elemental composition analysis, its...

Tsafack S, Degrande A, Franzel S, Simpson B. 2014. Farmer-to-farmer extension in Cameroon: a survey of extension organizations. ICRAF Working Paper No. 182. Nairobi, World Agroforestry Centre.

Sygnola Tsafack & Degrande Ann
This dataset was moved to: https://doi.org/10.34725/DVN/VQXGPVDespite the central role that farmers play as agricultural producers in developing countries, they are often inadequately served by research, extension and advisory services. Extension approaches such as the farmer-to-farmer extension (F2F) approach were developed to improve service to farmers, but little is known about how this approach is being used in Cameroon. This paper examines the experiences of organizations using the F2F extension approach. Specifically, the study characterizes and...

Replication Data for: Can gender appreciation of trees enhance landscape multifunctionality? A case of smallholder farming systems on Mount Elgon

Mieke Bourne, Joan Kimaiyo, Joseph Tanui, Delia Catacutan & Verrah Otiende
This dataset was moved to: https://doi.org/10.34725/DVN/SCKGMVTrees provide livelihood support functions and environmental services that contribute to the multifunctionality of landscapes. The presence or absence of trees is influenced by the interactions between ecological, social-economic and cultural elements. The role of gender in land use perceptions and changes involving trees have received little attention. In Africa, gender differentiated access, use and decision-making related to trees are common features. Divergent control and access to resources by men...

Rodel D. Lasco, Marya Laya O. Espaldon & Christine Marie D. Habito
This dataset was moved to: https://doi.org/10.34725/DVN/SCA37FRecent studies have highlighted the importance of trees and agroforestry in climate change adaptation and mitigation. This paper analyzes how farmers, members of their households, and community leaders in the Wahig–Inabanga watershed, Bohol province in the Philippines perceive of climate change, and define and value the roles of trees in coping with climate risks. Focus group discussions revealed that farmers and community leaders had observed changes in rainfall and temperature...
