The purpose of this study is to systematically identify and examine the challenges and opportunities of ecotourism development in Wondo Genet and its vicinity, southern Ethiopia and thereby forward suggestions to pertinent ecotourism stakeholders.

This study uses a mixed-method research approach and collects primary data from 412 research participants (400 survey respondents and 12 interviewees). Descriptive and inferential statistics and content analysis are used to analyze quantitative and qualitative data, respectively.

The research findings unfold several constraints that deter successful ecotourism development along with opportunities that can be used in future development. Ecotourism is suggested as a complementary form of tourism development in Wondo Genet and its vicinity, as the area is known for its natural and cultural resources.

The findings offer substantive insights to policymakers, private investors and local communities about the existing challenges and opportunities of ecotourism development in the context of emerging destinations. Given time, budget and human resource are acute restraints in developing countries; the current study is relevant in terms of highlighting the most pressing challenges that demand urgent action to unleash the development of a sustainable tourist destination.

The findings of this study also provide crucial practical implications to various stakeholders about the complementary nature of ecotourism and sustainable placemaking to conserve destinations’ environmental resources while improving socioeconomic conditions.

Despite Wondo Genet's immense ecotourism resource potential as one of the prime destinations both in the country and in the region, a huge gap exists in the current literature, where the current study intends to bridge in a comprehensive manner.

The textile industry is evolving toward nanotechnology, which provides materials with self-cleaning properties. This paper aims to provide a thorough explanation of the green synthesis and mechanism of ZnO nanoparticles, with prospective applications of zinc oxide nanoparticles (ZnO NPs) in self-cleaning textiles.

This review introduces a green mechanism for the synthesis of ZnO NPs using plant extracts, their self-cleaning properties and the mechanisms of physical, chemical and biological self-cleaning actions for textile applications.

ZnO NPs are among the several nanoparticles that are beneficial for self-cleaning textiles because of their exceptional physical and chemical properties, although review publications addressing the use of ZnO NPs in textiles for self-cleaning are uncommon. These results indicate that the plant-synthesized ZnO NPs display excellent biological, physical and chemical self-cleaning properties, the mechanism of which involves photocatalysis, surface roughness and interactions between ZnO NPs and bacterial surfaces.

Nanoformulations of plant-synthesized ZnO have been reviewed to achieve promising self-cleaning textile properties and have not been reviewed earlier.

Total organic carbon (TOC), dissolved organic carbon (DOC) and other physicochemical parameters of the Birim River, which serves for drinking and domestic purposes for rural mining communities, were analysed to assess the suitability of water quality for human consumption.

In total, 40 samples were collected from 20 sampling sites during the rainy season from July to September and the dry season from December to February in addition to two repeat samples and two blank samples. Samples were analysed for physiochemical parameters and the results were compared with World Health Organisation standards (WHO).

Data obtained for both rainy and dry seasons indicated TOC ranged from 1.1 to 7.3 mg/L and DOC 1–7.2 mg/L; pH, 5.6–8.63; temperature, 23.3–29.3°C; turbidity, <1.00–869NTU; apparent colour, <2.5–600 mg/L Pt-Co; true colour <2.5–150 mg/L Pt-Co; alkalinity, 27.8–80.4 mg/L; total suspended solids, <1.00–998 mg/L; electrical conductivity, 82–184 µS/cm; and bicarbonate, 33.9–98.1 mg/L. Particulate organic carbon (POC) was constituted between 1 and 10% of the TOC. Values for pH, turbidity, total suspended solids, and true colour indicated contamination of the river. p -value of <0.05 between seasons for the physicochemical parameters also suggests that the water is polluted.

Water from the Birim River is unsuitable for human consumption and may constitute a serious health risk to the consumers.

The paper yields immense value to inhabitant of communities using surface water affected by mining activities, policy makers in sustainability. It warns of the unsuitability of water from the Birim River for human consumption due to the potential health risk to consumers.

The purpose of this paper is to examine the career trajectories of 66 distinguished African agricultural professionals in order to explore how agricultural education and training (AET) institutions can better motivate and prepare youth for productive careers in Africa’s rapidly changing agrifood system.

Based on in-depth qualitative interviews with these role models, the paper explores the answers to two critical questions: How can Africa motivate its youth to consider careers in agriculture and agribusiness? How can AET institutions better prepare youth for productive careers in agribusiness?

Rural youth enter agribusiness careers in response to clearly perceived rural needs coupled with demonstrable profitability of modern agricultural and agribusiness opportunities. In contrast, urban youth embark on agricultural career paths in response to inspiring science education, particularly practical applications in biology, coupled with emerging awareness of the range of professional opportunities afforded by modern agribusiness and commercial agriculture.

The study relies on the basic premise that seasoned, successful professionals – from the private and public sector – can offer useful insights into ways of improving job preparation training for the youth of today seeking careers in the food system of tomorrow. The approach assumes that the role models have both the practical experience and forward-looking vision necessary to identify key elements of preparation likely to benefit future job market entrants.

This paper relies on primary interviews with distinguished agricultural professionals from 14 different African countries.
