“…This agricultural encroachment into woodlands, protected areas, and communal forests intensifies firewood scarcity as accessible resources dwindle for local communities (Mutekwa & Gambiza, 2017; Ndlovu et al, 2020). Harvesting of firewood beyond sustainable yield levels threatens the disappearance of key indigenous tree species (Mujaju et al, 2021). Zimbabwe has lost over 30% of its forests since 1990 (Matsa et al, 2021; Zvobgo & Tsoka, 2021).…”

Against the backdrop of Zimbabwe's captivating tourism landscapes and cultural heritage, energy sustainability challenges loom large. The paper investigates multifaceted relationship between, three independent variables: (reforestation program and funding, invasive tree species use, efficient cookstove adoption), one mediator: (green tourism supply chain behavior) and one dependent variable: (firewood energy sustainability). A quantitative approach was employed, collecting data from 483 tourists using simple random sampling and the Krejcie and Morgan table for determining the sample size. Questionnaires were distributed via Google forms, and structural equation modeling (SEM) was utilized for data analysis. Statistical findings indicate direct and indirect significant relationship between aforementioned variables and T‐statistics values all hypotheses were all greater than the threshold of 1.96. Ranging from a minimum of 2.515 to a maximum of 15.779. The findings pinpoint the importance of an integrated approach in Zimbabwe's tourism supply chain so as to address firewood energy sustainability and efficiency challenges stemming from costly renewables, weak policies, scarce electricity, and extensive deforestation. The study recommends tourism supply chain and policymakers to implement regulations on invasive species, offer incentives for technology adoption, practice and monitor green tourism supply chain practices within Zimbabwean tourism. The study's recommendations contribute to the ongoing discourse on fostering responsible energy practices within the tourism sector, aligning with global sustainability goals and future policy considerations.

“…The emergence of alien species is not a recent phenomenon; it may be dated to the introduction of agriculture about 10,000 years ago, which also heralded the introduction of pests (Gren, 2008). Some species that were introduced for various reasons have expanded their range beyond the original introduction geographical locations by becoming naturalized in their new surroundings (Mujaju et al 2021).…”

Invasive alien pests have caused a considerable negative impact on socio-economic growth and development in the South African agricultural sector. An effective strategy called horizon scanning has recently gained momentum in assessing the preparedness level for prospective changes or threats by invasive alien pests. The study was conducted to identify and prioritize pests already occurring elsewhere in Africa that are likely to be introduced in the Republic of South Africa as well as to develop pest risk analysis reports, pest risk management measures, surveillance procedures, regulatory framework and pest response strategies. The current study revealed that out of 97 known alien invasive arthropods, only 22 invasive pests are considered to have the highest potential risk of being introduced to South Africa. Among these, 8 were Hemiptera, 6 Coleoptera, 5 Diptera, 2 Lepidoptera, one Thysanoptera. Most arthropods (80%) were likely to arrive as contaminants on plant commodities. The pests with the highest scores were Maconellicoccus hirsutus, and Thrips palmi. Both M. hirsutus, and T. palmi have higher potential for entering and establishing in the country as they are important pests of plants. Zygodacus cucurbitae, Bactrocera latifrons, B. zonata, Paracocus marginatus, and Pectinophora gossypiella were the second most economic pests in terms of likelihood of entry and establishment in the country. Complete pest risk assessments and surveillance for the presence or introduction of pests in the country were the most frequently recommended phytosanitary measures against highly prioritised pests with the highest scores. Plants and plant products are the primary pathways for these prioritised pests.

“…In some cases fundamental ecosystem services, such as primary productivity, can be at risk from them (Wang et al, 2021). Invasive alien plant species can also exacerbate poverty and threaten the livelihoods of people, particularly in developing countries (Mujaju et al, 2021).…”

Calling time on alien plantscapes

Both urban and rural environments around the globe have become dominated by alien plant species to the extent that plantscapes from one region or country have become difficult to distinguish from many others. This process of plant community homogenisation comes at a cost to cultural identity and undermines people's sense of place. Although invasive alien plant species have received considerable attention in recent decades, issues with non‐invasive alien plant species have largely been ignored, and yet they contribute significantly to biotic homogeneity and impose an ever accumulating invasion debt: a debt that increases in proportion with their population sizes. By contrast, an abundance of native species in the places where people live is important for strengthening commitment to biodiversity conservation. Is there therefore sufficient evidence of harm from increasing numbers of non‐invasive alien plants to justify local and central governments introducing measures to substantially reduce the proportion of non‐invasive aliens in both urban and rural environments?
