The Adoption of Improved Agricultural Technologies - a Meta-Analysis for Africa

Abstract

Lamanna's contribution. We would like to thank Janie Rioux (Green Climate Fund) for her support during the classification of practices captured in the data and supervision of a research assistant for data extraction. We thank the following research assistants, who conducted the systematic literature search, screening and data extraction for this paper:

The complementarity and substitutability of sustainable agricultural practices among maize farm households under AFRINT regions in Ghana: Do the socioeconomic determinants confirm these?

“…The results show some degree of complementarity and substitutability of some SAPs (Arslan et al, 2020;Rajendran et al, 2016;Teklewold et al, 2013;Usman et al, 2020). Thus, the correlation coefficient of the error terms reveals that there is positive (complementarity) and negative (competitiveness) correlation between different components of the SAPs.…”

“…The principle of SAPs adoption does not exclude the adoption of external inputs but encourages their incorporation to complement domestic resources (Zaharia, 2010). SAPs help to maintain water retention, increase carbon sequestration, improve soil fertility, and protect the land from erosion (Arslan et al, 2020;Rajendran et al, 2016;Teklewold et al, 2013). Thus, the use of SAPs helps to achieve the twin goals of achieving higher productivity and positive environmental outcomes (Pretty et al, 2018;The Montpellier Panel, 2013).…”

“…By focusing on a single technology, we tend to ignore the possibility that farmers have a choice of adopting many agrarian technologies at the same time and that the adoption of one technology may be partially dependent on the earlier technology choice (Teklewold et al, 2013). Analysis of farm technology adoption without accounting for technology inter-dependency may under-or over-estimate the magnitude of the determinants of farmers' decision to adopt and the impacts of such adoption (Arslan et al, 2020;Azumah et al, 2018;Donkoh, 2019). This study, therefore, helps to fill this gap in knowledge by identifying the factors influencing the simultaneous adoption of multiple farm practices.…”

Perceptions of smallholder farmers on nature-based income generating activities as potential livelihood and biodiversity conservation strategies in Uluguru Mountains, Tanzania

“…The external factors influencing farmers' perception of NIGAs include the existing transforming structures and processes, such as, the public and private institutions supporting and promoting the adoption of NIGAs, laws, policies, culture, access to extension services, access to information, and training (Abdul-Gafar et al, 2016;Arslan et al, 2020). The expected outcomes are then mirrored from the actual outcomes which includes increased income, improved food security, improved wellbeing, reduced vulnerability, reduced land degradation and enhanced ecosystem resilience, as well as improved biodiversity conservation and more sustainable use of natural resource base.…”

Urban Expansion and Its Effect on Agricultural Technology Adoption of Smallholder Peri-Urban Farmers in Tigray Region, Ethiopia

“…A study conducted in China reveals that farmers' experience, training and positive attitude to agricultural technology adoption are limiting factors to adopt agricultural packages (Li et al, 2020). A panel data collected from 25 counties in Africa reports policy-related tools like access to information, access to credit, and wealthrelated factors like land size, livestock possession and off farm-income are positively related to the adoption of agricultural technologies (Arslan et al, 2020).…”
