Ethiopia faces a growing challenge of balancing natural resource utilisation with long-term sustainability. Its linear economic model leads to unsustainable waste generation from agriculture, urban populations, and the industry sectors. This paper explores the potential of a circular bioeconomy (CBE) as a solution. By promoting closed-loop systems that minimise waste and maximise resource use, CBE offers a pathway for Ethiopia to achieve sustainable resource management, economic growth, and better livelihood opportunities. CBE business models create valuable products such as organic fertiliser, biochar, bioenergy, and alternative proteins. CBE practices provide new income opportunities for farmers and urban dwellers and reduce the country’s reliance on virgin resources, chemical fertiliser, and non-renewable energy while addressing environmental pollution and soil depletion. Major organic waste streams in Ethiopia that could be recovered and reused include agricultural crop residues, animal manure, human excrement, and industrial sludge. Addressing the vast untapped potential of resource recovery from waste, this study analyses opportunities and challenges associated with promoting CBE in Ethiopia, focusing on analysing the regulatory framework, business licensing and registration procedure, government support, access to finance, and business support services. The paper employs a comprehensive desk review of peer-reviewed literature complemented by grey literature to capture recent trends or non-traditional research aspects. Semi-structured interviews with sector experts were conducted to fill information gaps. Key findings of this study are that a robust regulatory framework, streamlined business registration, and access to finance are critical for creating an enabling investment climate for CBE. Government support, business networks, and support services can empower CBE ventures and contribute to sustainable resource management. By focusing on policy interventions that combine sustainable waste management and livelihood creation, CBE can significantly contribute to achieving a more sustainable development path for all Ethiopians.

The Tank Cascade System (TCS) is an ancient, man-made rainwater harvesting and irrigation system unique to Sri Lanka’s dry zone. An ecosystem in itself, the TCS consists of an intricate network of small to large ‘tanks’ positioned along a gradient and connected through a series of canals. Within the system, paddy fields and dense forests coexist providing habitats for socio-ecologically significant species. Historically, the system has been crucial in drought and flood mitigation. Furthermore, fully functioning TCSs harvest copious amounts of rainwater, which is primarily used for irrigation to enable year-round crop production by the farming communities of the cascade landscape. The system’s important role in food security, rural livelihoods and local culture led to its designation as a Globally Important Agricultural Heritage System in 2017. Despite the TCS’s significance, the system has been deteriorating, and its sustainability is threatened by widespread tank neglect, rapid land use changes and biodiversity loss –the impacts of which are exacerbated by the effects of climate variability. There is national interest in safeguarding the TCS, though. The system has been recognized in Sri Lanka’s 2016-2025 National Adaptation Plan for Climate Change Impacts and within the 2021 Nationally Determined Contributions as an important Nature-based Solution (NbS) for strengthening national climate resilience. However, there is little evidence of this national support translating into on the ground action and of effective solutions to the challenges threatening TCS sustainability. This case study aims to fill these evidence gaps by sharing findings from research and project activities carried out under the Healthy Landscapes project. With a special focus on mainstreaming biodiversity and strengthening cascade ecology, the project rehabilitated and promoted the sustainable management of the TCS. This case study will highlight pathways for TCS rehabilitation to strengthen its function as a NbS, including associated challenges and further opportunities. As the cascade landscape community plays an important role in climate adaptation and resilience within the country's dry zone, we also emphasize the importance of investigating their perceptions of current national policy and formulating localized adaptation strategies that benefit climate resilience, food security and rural livelihoods.

Shortage of pullet supply and high mortality of local chicks arising from diseases and inadequate feed were the main challenges identified through a rapid diagnostic survey on the poultry value chain in Dale. Accordingly, women group-based commercial pullet rearing as an input for smallholder poultry production was initiated by the Office of Agriculture and Rural Development (OoARD) and IPMS. To develop the program, a credit scheme was initiated using IPMS’s credit innovation funds. With assistance of OoARD, eighty women subdivided into five (village) groups, collectively purchased 4000 day-old chicks (50/woman) and other inputs such as feed, vaccines, hay box brooder and watering equipment. The women were trained and developed their skills through their group structures. The required vaccinations were also given by the women themselves under the auspices of the group structures. After 4–5 months, 3470 pullets survived and were kept by the women or sold to others for egg producers. Empirical results show that: i) the group approach helped to improve linkages, communication, and access to knowledge, technology, finance, inputs (day-old chicks and feed), veterinary service, and market; ii) the groups were able to successfully produce and supply pullets thus making an additional income of Ethiopian birr (ETB) 833/hh; iii) the approach stimulates growing demand for the 5 months-old pullets, especially by government/donor financed programs. While being technically and economically viable, the system requires institutional upgrading so as to ensure sustainability of input supply (chicks, feed and vaccine/drugs). The commitment shown by WoARD to provide technical backstopping in all aspects of poultry production also leaves much to be desired. These are crucial at least for the first few cycles, while more emphasis should be given to promoting improved local birds. As the follow-up studies on subsequent egg production showed, considerable attention needs to be paid to building the capacity of poultry farmers to engage in semi-commercial egg production, since egg production was still far below its potential. The study also shows that a difference of as high as 35% existed between egg production level by households who had purchased the pullets privately and households who had received the pullets through food security funded projects in Dale area.

Since the reform and opening-up in 1978, China’s income distribution gap has widened. The Gini coefficient of national residents’ income rose from 0.31 in 1981 to a historic high of 0.49 in 2008 and has continued to hover at a high of 0.46 in the recent years (Molero-Simarro, 2017; Li and Zhu, 2018; Luo et al., 2021). Narrowing the income gap between urban and rural residents is the key to reducing China’s Gini coefficient. The ratio of per capita income between urban and rural residents exhibited an overall growth trend before 2009, despite the increase in disposable income per capita of rural residents from 134 yuan in 1978 to 18,931 yuan in 2021. In 2007, the urban–rural income ratio exceeded 3:1 for the first time and contributed over 50% to the Gini coefficient of the national income distribution (Li and Wan, 2013). Since 2009, the urban–rural income gap has decreased; however, the decline has nearly halted post 2014. In 2021, the urban–rural income ratio was still as high as 2.5:1, almost equal to that in 1978 and larger than that in developed countries, which have a level of approximately 1:1 or lower.
