Abstract: The high rate of urbanization in Nigerian cities has intensified environmental problems such as urban heat islands and deteriorating air quality. These challenges are further increased by traditional roofing systems, which retains heat and increase runoff of stormwater. Green roof systems, a subset of the broader concept of green infrastructure, presents a viable solution by providing significant microclimate and environmental benefits. In Nigeria, adoption of green roofs is still on the low scale, despite their suitability for tropical climates. The review sets out to examine the current state of green roof adoption in Nigeria by synthesizing fifteen peer-reviewed articles published between 2000 and 2025 and retrieved from Scopus and Google Scholar databases respectively. The findings indicate that there is growing level of academic and professional interest and less practical implementation. Most of the reviewed studies are geographically concentrated in Lagos. Empirical and simulation-based evidence suggests that green roofs are able to lower surface temperatures by 10-25°C and improve indoor comfort by up to 3°C. However, obstacles to implementation include cost of high installation, unskilled personnel, shortage of local standards and weak policy guidelines despite their benefits. The study concludes that through proper advocacy and localisation, green roofs could become a key tool of environmental resilience and sustainable cities in Nigeria.

Abstract: Commercial risk is inherent and symbiotic to technological innovation, as a consequence of its naturally novel character, which entails a greater or lesser degree of market unfamiliarity. This article presents a conceptual framework composed of a group of-first-ten laws or principles of Technological Innovation Marketing, derived from an inductive approach based on more than a decade of marketing analysis of technologies belonging to sectors such as biotechnology, agribusiness, mining, environmental technologies, software, health and energy, among many others. The laws articulate general principles related to functionality, performance, market objection, adoption costs, functional specialization, indirect competition and technological transversalities. The analysis is supported by interdisciplinary literature on technology, marketing, institutional economics and diffusion of innovations, and is complemented by multiple real cases that are empirically retro-validated against the patterns described, consolidating the underlying concepts. The results reveal that functionality constitutes the primary value of any technology; that market resistance is structural and proportional to the degree of disruption; that perceived value depends on the integral cost of adoption; that specialization of technology increases value but reduces market size; and that every innovation faces pre-existing competition. The proposed model not only provides a coherent explanation of commercial risk, but also offers a practical tool for the validation, communication and adoption of emerging technologies. The expository structure allows any reader, with greater or lesser degree of specialization, within the framework of any territorial or technological reality, to re-think their own technology or technological innovation from the principles developed (bottom up) and, on that basis, return to it with greater commercial understanding (top down). Finally, the evolutionary character of the framework is recognized, opening the possibility of additional laws derived from new research and future evidence.
