The growing demand for sustainable agricultural and environmental practices in Nigeria requires
the effective use of digital communication tools to promote awareness and behavioural change.
This study examines the role of digital communication competence in advancing agricultural and
environmental awareness, drawing on the Diffusion of Innovations Theory and the
Communication Competence Theory as guiding frameworks. The Diffusion of Innovations Theory
explains how tools such as WhatsApp, Facebook, and mobile platforms spread across adopter
categories in Nigerian communities, while the Communication Competence Theory highlights the
linguistic, sociocultural, strategic, and digital skills necessary for interpreting and applying
information effectively. Using case illustrations from WhatsApp farmer groups, social media
based environmental campaigns, and mobile extension platforms like the e-wallet, the study
demonstrates that ICT adoption expands communication channels but is constrained by barriers
such as language, low digital literacy, and rural-urban infrastructure gaps. The findings indicate
that digital adoption alone is insufficient without communicative competence to ensure that
technical information is clear, context-sensitive, and actionable. The study recommends
integrating English proficiency and digital literacy into agricultural and environmental curricula,
strengthening policy frameworks to prioritize competence, and fostering multi-stakeholder
collaboration in line with the Sustainable Development Goals. Bridging ICT adoption with
communication competence is critical to achieving food security, environmental sustainability,
and inclusive rural development in Nigeria.
