“…In Gyamfiase‐Adenya‐Obom, Enu‐Kwesi (1997) observed that 52 per cent of the plant life forms of fallows were herbs and shrubs, and identified C. odorata as the single most dominant species. Similarly, Awanyo (2007) identified C. odorata as the most frequently occurring species in the fallow vegetation of the same study area, with a 60 per cent likelihood of finding it in random quadrats. C. odorata dominance continues into the cultivation phase because of its massive soil seedbank, which remains during fallows and which provides numerous viable seeds during the cultivation period (Ekeleme et al 2004, 29).…”

An important limiting factor on labour-intensive small-scale agricultural production in Ghana is competition from weeds for environmental resources, such as soil nutrients, moisture and sunlight. This article combines primary social research based on surveys and in-depth interviews, and ecological research based on experiment and secondary research to explore the efficacy of three land use management practices, compared with their alternatives, in dealing with on-farm weed problems in Gyamfiase-Adenya-Obom, Ghana. The fallow management practice of >3 years of fallow showed significantly greater promise of suppressing weeds than ≤3 years of fallow. Mulching slashed vegetation, as a land preparation practice, was also consistently better at reducing weed densities than burning the slashed vegetation. The study indicated that while more frequent weeding was generally more effective in suppressing weed densities than less frequent weeding, the effect of weeding in significantly reducing weed densities was not associated with weeding frequency per se but with how carefully weeding was accomplished.

“…The rapid expansion of agriculture, and of cocoa production in particular, has led to substantial habitat conversion in Ghana (Benhin and Barbier 2004 ). It has been estimated that as much as 80% of Ghana’s primary forest cover has been converted or degraded over the last century (Opoku 2006 ; Awanyo 2007 ). This has direct implications for hunting.…”

Wild animals play an integral and complex role in the economies and ecologies of many countries across the globe, including those of West and Central Africa, the focus of this policy perspective. The trade in wild meat, and its role in diets, have been brought into focus as a consequence of discussions over the origins of COVID-19. As a result, there have been calls for the closure of China’s “wet markets”; greater scrutiny of the wildlife trade in general; and a spotlight has been placed on the potential risks posed by growing human populations and shrinking natural habitats for animal to human transmission of zoonotic diseases. However, to date there has been little attention given to what the consequences of the COVID-19 economic shock may be for the wildlife trade; the people who rely on it for their livelihoods; and the wildlife that is exploited. In this policy perspective, we argue that the links between the COVID-19 pandemic, rural livelihoods and wildlife are likely to be more complex, more nuanced, and more far-reaching, than is represented in the literature to date. We develop a causal model that tracks the likely implications for the wild meat trade of the systemic crisis triggered by COVID-19. We focus on the resulting economic shockwave, as manifested in the collapse in global demand for commodities such as oil, and international tourism services, and what this may mean for local African economies and livelihoods. We trace the shockwave through to the consequences for the use of, and demand for, wild meats as households respond to these changes. We suggest that understanding and predicting the complex dynamics of wild meat use requires increased collaboration between environmental and resource economics and the ecological and conservation sciences.

“…Birth Attendants (TBAs) and herbal practitioners in rural Ghana rely mostly on natural plants for their medical applications (Ahenkan & Boon, 2011;Asase & Oppong-Mensah, 2009). However, biodiversity-unfriendly practices have been causing the gradual extinction of the natural plants used for medical applications and research purposes (Awanyo, 2007). The continuous development and promotion of herbal medicine depends on the survival of the natural plant species.…”
