Research reveals strong community willingness to protect declining wildlife in southern Ethiopia

The investigation, which was carried out through household surveys, focus group discussions, and field observations, revealed that local wildlife populations are under critical strain.

A new study published in the open-access journal BioRisk has highlighted a powerful wave of local support for wildlife conservation in the Hamer District of South Omo, Ethiopia, despite severe environmental pressures.

Researchers from the Ethiopian Biodiversity Institute, the Gullele Botanic Garden, and the University of Szczecin investigated the primary factors driving habitat degradation and evaluated whether communities are prepared to support future conservation strategies.

The investigation, which was carried out through household surveys, focus group discussions, and field observations, revealed that local wildlife populations are under critical strain. An overwhelming majority of the surveyed residents, precisely 82.3 per cent, reported a noticeable decline in wild animal numbers within their vicinity.

Participants identified deforestation and overgrazing as the most significant hazards to local biodiversity, with 63.5 per cent selecting forest clearing as the primary threat and 50.0 per cent identifying livestock overgrazing as the secondary threat. These human-induced activities are exacerbated by recurrent droughts and changing climate patterns, forcing pastoralist communities to venture deeper into natural habitats to seek fodder and water for their livestock.

Despite facing these daily challenges for survival, the local community demonstrated a remarkable commitment to environmental stewardship. The researchers found that 90.6 per cent of the respondents expressed an explicit willingness to participate actively in future wildlife conservation initiatives.

Further, 96.9 per cent of those interviewed acknowledged that the responsibility to safeguard local species rests directly with the community itself, while 99 per cent stated that intervention programmes are an urgent necessity. Statistical modelling demonstrated that factors such as the specific locality, gender, marital status, and length of residence significantly influence an individual’s openness to conservation efforts.

The study notes that local inhabitants traditionally interact with wildlife for various purposes, including utilising certain species for food, traditional remedies, or cultural decorations. However, these practices, combined with habitat loss, have pushed several animals to the brink, leaving the local presence of iconic species such as giraffes and ostriches highly uncertain.

To foster sustainable coexistence between humans and wild animals, the authors recommend implementing managed livestock husbandry practices and constructing dedicated water ponds to alleviate resource competition during dry spells.

They also advocate for the promotion of ecotourism, community-led management initiatives, and stricter enforcement of wildlife protection laws to curb illegal hunting and habitat destruction in the region.

High-schoolers join scholars to lift the lid on Hong Kong’s soil biodiversity

Most often, the students would find millipedes. They even helped identify two species that are new to Hong Kong’s fauna.

Soil and its macrofauna are an integral part of many ecosystems, playing an important role in decomposition and nutrient recycling. However, soil biodiversity remains understudied globally.

To help fill this gap and reveal the diversity of soil fauna in Hong Kong, a team of scientists from The Chinese University of Hong Kong initiated a citizen science project involving universities, non-governmental organisations and secondary school students and teachers.

“Involving citizens as part of the new knowledge generation process is important in promoting the understanding of biodiversity. Training younger-generation citizens to learn about biodiversity is of utmost importance and crucial to conservation engagement”

– say the researchers in their study, which was published in the open-access Biodiversity Data Journal.

Working side by side with university academics, taxonomists and non-governmental organisation members, students from 21 schools/institutes were recruited to collect soil animals near their campusesfor a year and record their observations.

Between October 2019 and October 2020, they monitored and sampled species across 21 sites of urban and semi-natural habitats in Hong Kong, collecting a total of 3,588 individual samples. Their efforts yielded 150 soil macrofaunal species, identified as arthropods (including insects, spiders, centipedes and millipedes), worms, and snails.

Most often, the students found millipedes (23 out of 150 species). They even helped identify two millipede species that are new to Hong Kong’s fauna: Monographis queenslandica and Alloproctoides remyi. The former is usually found in Australia – the researchers suggest it might have been introduced to the area many decades ago from Queensland or vice versa – and the latter has been observed in Reunion and Mauritius.

Two polyxenid millipede species, collected in this study, turned out to had never before been recorded from Hong Kong.

Millipedes like these two species can accelerate litter decomposition and regulate the soil carbon and phosphorus cycling, while earthworms can modify the soil structure and regulate water and organic matter cycling.

“Before the beginning of this project, the understanding of soil biodiversity in Hong Kong, including the understanding of its contained millipede species, was inadequate”

the researchers write in their paper.

Now, they believe that the identified macrofauna species and their 646 DNA barcodes have established a solid foundation for further research in soil biodiversity in the area.

Their project also serves an additional purpose. Unlike most conventional scientific studies, which are usually carried out by the government, non-governmental organisations or academics in universities alone, this study utilised a citizen science approach through creating a big community engaged with biodiversity. In doing so, it helped educate the public and raise awareness on the use of basic science techniques in understanding local biodiversity.

So, it may have inspired a new generation of future scientists: some students started millipede cultures in their own schools, and one school used the millipede breeding model to participate in a science and technology competition.

This study is a proof that local institutes and high schools can unite together with research teams at universities and perform scientific work, the study’s authors believe.

It “has raised public awareness and potentially opens up opportunities for the general public to engage in scientific research in the future.” 

The team hopes that their approach could inspire future biodiversity sampling and monitoring studies to engage more citizen scientists.
