Leveraging Oromo Indigenous Knowledge for Climate-Resilient Agriculture and Sustainable Food Security

1. Introduction

Scholarly work on agrarian transformation in Ethiopia consistently highlights the disruptive effects of state-led modernization on indigenous production systems. Dehu’s 2023 historical study of the Maccaa Oromo (1975–2015) demonstrates how land-use restructuring, state farms, resettlement schemes, and the introduction of chemical-intensive agriculture undermined ecologically grounded indigenous farming practices. Oromia possesses one of Africa’s most ecologically diverse agricultural landscapes, ranging from semi-arid lowlands to high-rainfall highlands (Hurni 1998). This diversity supports a wide range of crops, livestock systems, and forest resources. More than 80% of Oromia’s population depends on agriculture, making sustainable land management central to livelihoods and efforts for food security (Bonger et al. 2004). The Maccaa Oromo case exemplifies how state interventions, whether socialist (Derg) or neoliberal (EPRDF), consistently marginalized Oromia’s indigenous ecological knowledge, reduced farmers’ access to land and weakened community control over food systems. Although indigenous Knowledge (IK) systems accumulated, adapted, and transmitted across generations have long guided land stewardship, water management, and environmental ethics among the Oromo people (Asfaw and Agren 2007; Workneh 2001), the rapid environmental change, population pressure, misuse of land, and the erosion of traditional ecological norms have intensified land degradation and reduced productivity (Bishaw 2001; Tesfaye and Woldeamanuel 2014).

Knowing the deep-rooted Oromo indigenous knowledge of farming, one may ask how Oromo Indigenous Knowledge systems can contribute to climate-resilient agriculture and sustainable food security in Oromia, and how these systems can be effectively integrated with contemporary agronomic approaches. We made several literatures review and analysis related to indigenous knowledge, natural resources, climate resilience, farming and sustainable food production, and food security to produce this informative paper. Information was extracted from eligible studies including publication details, objectives, and major findings. The authors have deep knowledge of the region’s ecosystem, indigenous farming approaches and the changing climate and these factors exacerbated hinderances to sustainable food production. We believe that Climate adaptation strategies that do not incorporate local ecological knowledge and cultural institutions may face implementation challenges and lower community acceptances. This suggests that Indigenous Knowledge should be considered as a complementary component of climate adaptation planning. This review examines how Oromo Indigenous Knowledge contributes to climate-resilient agriculture and sustainable food security in Oromia. Specifically, it synthesizes evidence on indigenous environmental ethics, agricultural practices, and governance institutions; evaluates the pressures that are undermining these systems; and proposes a framework for integrating Indigenous Knowledge with contemporary agronomic innovations. By bringing together literature from agriculture, environmental studies, governance, and public health, the review seeks to identify pathways for culturally grounded and ecologically sustainable development and food production.

Conceptual Framework: Indigenous Knowledge-Based Climate Resilience

Oromo Indigenous Knowledge contributes to climate resilience through the interaction of four mutually reinforcing domains: (1) Ecological Knowledge (weather indicators, seasonal calendars, seed selection, mixed farming systems, grazing management), (2) Environmental Ethics (Safuu, Aadaa, stewardship norms), (3) Governance Institutions (Gadaa, Jaarsummaa, Araara, Siiqqee, customary resource governance, and (4) Agricultural Practices (intercropping, agroforestry, rotational grazing, manure application – cicaata, water management). These domains influence biodiversity conservation, soil health, water security, adaptive capacity, livelihood resilience, which ultimately affect climate resilience, food security, sustainable development, and public health outcomes.

Indigenous Knowledge Systems and Climate Resilience

The need for agrarian change in Ethiopia has long emphasized production systems, land tenure, and state-led development, yet the cultural, ecological, and food-system dimensions of these transformations remain insufficiently explored or are simply used to marginalize the farmers, particularly in Oromia where land resource is ample and has become a target of interest for various entities. Because of the diverse interest on Oromia’s farmlands, the rapid population growth, and environmentally unsound development practices have accelerated natural resource degradation in this region (G. Desalegn et al. 2013; Zewde 2008). State policies and national development agendas further reshaped human–land relations, altering access to resources and altered traditional cultivation.

Research on the Rift Valley and western Ethiopia provides additional context. Getnet et al. (2005) documents how commercial agriculture transformed production systems in the Awash Valley, shifting livelihoods from livestock-based systems to commercial cereal production. The study does not fully address the ecological pressures or the implications of state-based commercial farms on local food cultures. Similarly, Hinew (2018) and Tefera (2009) examined the environmental impacts of state-sponsored and spontaneous resettlement in Oromia’s western lowlands, revealing extensive deforestation, ecological disruption, and cultural dislocation and disruption of the local population. Yet these studies stop short of linking environmental degradation to the erosion of food sovereignty or the loss of culturally significant cropping systems.

Indigenous land-use systems among the Oromo also provide a contrasting paradigm. Tesema’s pioneering work on the Maccaa Oromo demonstrates how indigenous cultivation practices, such as fallowing (lafa baasuu), intercropping (makaa facaasuu), manuring (ciicata), and mixed crop-livestock (silvo-pasture) systems maintained ecological balance and ensured diverse, culturally meaningful food production (Bachie and Burayu 2024). These systems were embedded in broader institutions of environmental stewardship, including customary land classifications (masi, lafa kaloo / dheechisa, daggala, bosona) and rotational grazing practices. Research among the Oromo people shows that Oromo’s indigenous environmental ethics promotes intergenerational responsibility, maintain sustainable resource use, and provides a holistic understanding of human–nature relations (Ketema and Ahmad 2019). These traditional values historically safeguarded forests, soils, water resources, and wild foods and are key components of a resilient food production system and food security.

Parallel scholarship on pastoral Oromo communities, particularly the Borana and possibly the Harar and Karrayyuu Oromo further illustrates the centrality of indigenous institutions in managing ecological variability. Debsu (2013) highlights how the Gadaa system, clan-based reciprocity networks (buusa-gonofaa, dabaree), and rangeland management practices historically enabled communities to cope with drought, maintain herd diversity, and preserve livestock mobility. However, increased drought frequency, state interventions, and land fragmentation have weakened these indigenous institutions, reducing adaptive capacity and undermining food security. The forced shift toward commercial crops, fenced rangelands, and chemical inputs in this area represents a broader trend in which external development agendas displaced ecologically grounded indigenous systems. In contrary to forced commercialization, Workineh (2001) and Kelbessa (2005) argue that Oromo ecological philosophy is rooted in moral obligations and maintain balance between humans and the natural ecosystem. In the same manner, studies in Bale (Ketema and Ahmad 2019) further showed that sacred groves, taboos, and customary institutions regulated forest use, water access, and exhaust grazing patterns. It must be known that the local ethical systems fostered sustainable resource management long before the emergence of modern “conservation” frameworks.

Studies on conflict resolution among the Oromo also underscore the integrative role of Gadaa institutions in managing land, water, and social relations (Usmane 2019). Oromo mechanisms such as Araara, Siiqqee, and Gadaa-based adjudication maintain social cohesion and regulate access to shared resources (Watson 2001; C. E. Desalegn et al. 2007). These systems are not merely cultural artifacts but functional environmental governance structures that influence land use, water allocation, and community-based conservation. These systems contributed indirectly to food sovereignty by maintaining social cohesion and equitable access to productive landscapes.

Despite the rich body of work, significant gaps remain between the indigenous knowledge-based resource management and the introduced resource exhaustive systems. Existing studies rarely examine how agricultural modernization—through land-use change ecological makeups, introduced chemical inputs, mono-cropping, and market-oriented production, hence has reshaped the cultural and nutritional dimensions of local food systems. The erosion of indigenous crops such as ancootee, qoccoo, nuugi, buna, and Oromo barley varieties, and the decline of wild food harvesting (such as badeessaa, mango (yes mango has been a wild crop in some parts of Oromia), goraa, etc), remain largely undocumented in mainstream agrarian literature, although these crops have been the contributory to Oromia’s local food system. Likewise, the relationship between state-driven development projects (state farms, resettlement, commercial leasing) and the loss of culturally appropriate foods has received limited scholarly attention. Taken together, the literature reveals three major gaps that this manuscript addresses: (1) Limited integration of indigenous environmental ethics with agronomic sustainability research, (2) Insufficient empirical linkage between agricultural modernization and food sovereignty in Oromia, and (3) Underrepresentation of Oromo ecological knowledge in climate resilience and land management discourse. This study contributes to filling these gaps by synthesizing environmental ethics, and modern agronomic strategies to propose a culturally grounded pathway toward sustainable

Some definitions

Climate change: Climate change refers to the long-term changes in global temperatures, weather patterns, and ecological systems, primarily driven by human activities such as fossil fuel combustion, deforestation, and industrial agriculture. In some regions, the effects of climate change are acute: rising temperatures, unpredictable rainfall, and increasingly frequent and prolonged droughts are transforming livelihoods in a region where pastoralism and rain-fed agriculture are essential for survival. Climate change constitutes a direct force shaping food security, disease prevalence, migration patterns, cultural continuity, violence and political stability (Dugassa et al. 2021; Dugassa 2023). The intensification of diseases demonstrates that climate change not only affects food production, transportation, storage, cooking and consumption, but also presents unprecedented challenges to human illnesses. For example, food insecurity causes malnutrition, underdevelopment of critical organs, tissues, cells, and affects growth and development, and an underdevelopment of immune system hinders the body’s ability to fight infections (Dugassa 2019).

Indigenous knowledge: For the Oromo, indigenous environmental knowledge represents deep ecological wisdom developed over centuries through sustained interaction with Oromia’s landscapes, seasons, and ecosystems. It encompasses a detailed understanding of rainfall cycles, soil variation, grazing patterns, plant and animal behaviour, and the seasonal rhythms of summer (bona), winter (ganna), autumn (arfaasaa), and spring (birraa). These knowledges are not documented in textbooks but are maintained within the collective memory of elders and preserved through proverbs, songs, and community practices. These traditional knowledges instruct community members in forest protection, pastureland management, water conservation, maintaining equilibrium among people, livestock, and the land. For instance, the teachings of grandmother Ba’ise Biqilee^[1] emphasizes the prohibition of indiscriminate tree cuttings and the killing of animals, particularly young females. The rationale provided is that Mother Nature created these trees and animals to reproduce, hence harming them contravenes the natural order. Ba’ise Biqilee and many Oromos advocate for planting a new tree when one is cut and refrains from consuming the meat of young female animals until they have produced at least one offspring.

2. Rationale for the Application of Indigenous Knowledge

The three central Oromo institutions—Gadaa, Siiqqee, and Qaalluu—have significantly shaped schedules, herd movements, soil conservation, and the preservation of sacred natural sites. Consequently, indigenous knowledge functions both as a practical environmental science and as a cultural ethic that maintains harmonious relationships between society and the natural world, ensuring the well-being of future generations. This review is extended from a presentation delivered by Bachie at the Kenyatta University OSA Conference in Nairobi, Kenya (April 10–14, 2025) with Dugassa contributing perspectives of public health from the standpoint of food production and food insecurity. We believe that the collaboration between agricultural and public health experts strengthens the potential for social transformation and supports the development of interventions that genuinely address community needs. This multidimensional approach ensures that research findings and / or reviews remain practical, actionable, and grounded in real-world challenges. By integrating these disciplines, the paper may advance a comprehensive Oromo Indigenous framework capable of addressing complex societal needs and enhancing community preparedness to mitigate climate change.

First, knowledge is socially constructed, although its validity varies across contexts. The Eurocentric and capitalist knowledge systems have historically prioritized the exploitation of human and natural resources. This orientation, along with the delegitimization of local knowledge may undermine systems that support environmental stewardship. For instance, during the Spanish invasion of South America, indigenous staple foods such as quinoa, chia seeds, and amaranth were considered sacred and offered to divine powers. Spanish conquerors, however, viewed these practices as regressive and prohibited their cultivation (Martínez et al. 2015; Angeli et al. 2020). Consequently, indigenous communities were forced to grow these crops in remote mountainous areas, while less nutritious foods like corn became globally popularized. In the same manner some special variety teff, known as the “manya” (xaafii aadii) is grown and sold to the well-to-do at higher prices. Such development has reduced the production of other stable food at the expense of money-making endeavours. Thus, seeking the Oromo knowledge system. This knowledge system guides decisions related to planting

solutions to the Oromo social problems and the endeavour to generate revenue must be viewed from the implementation of IK, balancing the needs and implications of food production systems. . Second, the Oromo people have developed a deep ecological memory over millennia through close observations. Along with other indigenous communities in the Horn of Africa, the Oromo has experienced centuries of drought cycles, shifting rainfall patterns, and ecological difficulties. These accumulated memories enable a detailed understanding of local microclimates, recognition of drought indicators such as animal behaviour, star patterns, wind shifts, and the use of seasonal calendars, such as the Oromo Ayaana system to document the happenings. Indigenous ecological memory among the Oromo provides predictive insights that are often overlooked or not fully understood by modern science. Integrating indigenous knowledge into agricultural practices for climate resilience. Fostering knowledge production consistent with the Oromo worldview enhances their problem-solving skills and empowers them to produce sufficient agricultural production and be food secure.

Third, the Oromo indigenous knowledge demonstrates effective adaptation strategies for addressing water scarcity and limited grazing land. Indigenous knowledge systems in this context could evolve to specifically withstand environmental challenges. For instance, the Oromo utilizes hora (mineral springs), communal water governance, and pastoral mobility routes to prevent overgrazing. These approaches are low-cost, sustainable, and inherently suited to arid and semi-arid environments, which makes them particularly effective for enhancing climate resilience. Such a knowledge system needs to be encouraged.

Fourth, the Oromo social governance systems, designed to prevent and reduce conflict and support collective action, also support fair distribution of scarce resources. In the Horn of Africa, climate change is not only an ecological issue—it’s deeply tied to food insecurity, conflict, displacement, resource competition and public health. The Oromo Indigenous governance systems, such as Gadaa, provide mechanisms for negotiating grazing rights, managing access to water, preventing resource-based conflict and coordinating mobility during drought. Those developed systems are culturally acceptable and financially feasible. Evidence from pastoral and agrarian systems suggests that strong social institutions enhance collective action, resource management, and adaptive capacity during climatic stress. Indigenous governance provides legitimacy, trust, and collective discipline that top-down policies often lack.

Fifth, the idea of promoting biodiversity conservation is rooted in the Oromo cultural ethics. Many Indigenous communities in the Horn maintain sacred ecological zones and cultural taboos that protect biodiversity. For example, the Oromo people have a concept of kallu forests and sacred groves, and they protect natural forests for their biodiversity. They preserve and popularize traditional seed preservation and drought-resistant crops (xaafi, sorghum, millet). Advancing biodiversity is a frontline defence against climate change. The Oromo indigenous ethics preserve species, soils, and watersheds that modern development often destroys.

Sixth, Adaptation initiatives that align with local cultural values may achieve greater legitimacy and participation among communities. When those groups who have a cultural perspective in unpalatable to the Oromo worldview present the Oromo people as tree worshipers, they are intended to discredit the Oromo people’s ethical and moral standard toward the natural world. The top-down climate interventions of the Ethiopian government fail because they ignore the Oromo worldviews, livelihoods, and spiritual relationships with land. Oromos indigenous knowledge about ecology aligns with pastoral and agro-pastoral livelihoods, stored in collective memory and transmitted through oral tradition, ritual, and community practices. Climate adaptation only works when communities see themselves as co-creators, not passive recipients of solutions.

3. Oromia’s Natural Resources and Agricultural Potential

Oromia’s ecological richness includes fertile highlands, semi-desert lowlands, and extensive river systems such as the Didhessa Angar, Gudar, Ganale, Awash, and Baroo (Oromia Water, Mineral and Energy Bureau 2018), and many other rivers and tributaries. Historically, the Oromia region maintained approximately 40% forest cover (Lamessa 2002), which supported water resources, biodiversity, moderated climate, and sustained soil fertility. Today, the water resources remain underutilized, particularly the rivers that could support year-round irrigation (Seyoum and Birhanu 2019), although the region’s natural endowments provide a strong foundation for sustainable agricultural intensification with careful management to prevent further degradation (Pretty 2008).

4. Indigenous Knowledge and Environmental Ethics

Complementing these agrarian histories, studies of Oromo environmental ethics (Ketema and Ahmad 2019) reveal a deep-rooted worldview that conceptualizes humans as integral rather than domination of resources. The Oromo ethical framework—expressed through concepts such as safuu (moral balance), aadaa (custom), and heera (law)—promotes intergenerational responsibility, sustainable resource use, and respect for natural resources. These indigenous ethics are embedded in everyday practices such as forest protection, soil conservation, and ritualized respect for sacred landscapes. While the Oromo traditions illustrate how environmental stewardship is transmitted through oral tradition, Gadaa institutions, and community rituals, modernization, market expansion, and cultural homogenization have threatened the continuity of these ethical systems, echoing the broader pattern of erosion in agrarian transformations. Debsu’s 2013 work on the Borana pastoralists provides a complementary perspective by examining how indigenous institutions mediate responses to climate stress. For example, the reciprocity networks, such as buusa gonofaa and dabaree, and the customary rangeland management practices enabled pastoralists to cope with drought, livestock mobility constraints, and resource scarcity. In the meantime, it was observed that increasing drought frequency, land fragmentation, and state interventions have weakened these adaptive systems. It is now widespread that Pastoralists face shrinking grazing lands, and declining herd resilience.

4.1. Oromo Indigenous Knowledge Systems

Encompasses farming practices, ecological observations, water management, and cultural norms that promote environmental stewardship (Yosef and Asmamaw 2015). Examples include: (1) Use of animal manure and urine as primary soil fertility sources (Asfaw and Agren 2007), (2) Rotational livestock pens (Dallaa loonii) to distribute nutrients (GemedoDalle et al. 2006), (3) Community-based water management systems (Seyoum and Birhanu 2019), (4) Traditional seed selection and mixed cropping systems (Abate 2016). These practices reflect a deep understanding of local ecosystems and long-term sustainability. The tourism narrative highlights the economic potential of these landscapes, but it also reveals tensions: commercialization, infrastructure development, and increased visitation can threaten the very ecosystems and cultural practices that attract tourists. This mirrors the broader pattern of external pressures reshaping indigenous land-use systems.

4.2. Environmental Ethics (Safuu)

Central to Oromo environmental philosophy is Safuu, a moral code governing interactions with nature (Workneh 2001). Cutting young, straight-growing trees is culturally unacceptable, and many communities maintain sacred groves and taboos that protect wildlife and forests (Bard and Bottero 2020). These ethics historically enabled harmonious coexistence of the Oromo people with the environment. The Oromo Gadaa system, jaarsummaa (elders’ mediation), araara (reconciliation), and women’s institutions such as siiqqee and ateetee form a multilayered conflict management framework. These mechanisms maintain social cohesion, regulate resource access, and prevent escalation—functions that are essential in agrarian and pastoral contexts where land and water are shared. Across all groups, traditional institutions serve as stabilizing forces that mediate disputes arising from resource scarcity, environmental change, and social transformation.

5. Challenges to Sustainable Agriculture in Oromia

Despite strong indigenous foundations, several factors have undermined Oromia’s agricultural sustainability:

5.1. Deforestation and Land Degradation

Studies documented severe forest loss in Oromia region in the early 2000s (Lamessa 2002), linking it to a combination of socio-economic pressures, environmental degradation, and political instability. For example, in the Walmara District of central Oromia Forest cover collapsed dramatically from 13.7% in 1985 to only 2.22% in 2017, primarily due to agricultural expansion, illegal wood extraction, and settlement growth (Urgessa and Hunduma 2023). The system accelerated soil erosion, reduced biomass, and altered hydrological cycles (Bishaw 2001) when Oromo’s indigenous knowledge is bypassed. Therefore, the persistence of Gadaa institutions, environmental ethics, and community-based conflict resolution demonstrates that Oromo indigenous knowledge remains a vital resource for building sustainable, culturally grounded development pathways, but erodes with the forceful interference of external forces, such as land grabbing and forced resettlements of culturally different societies that have not yet developed respect for the local ecological ethics.

5.2. Steep-Slope Cultivation

Approximately 60% of cultivated land lies on slopes of ~35%, where shallow soils are highly vulnerable to erosion (Tesfaye and Woldeamanuel 2014). Gullies, sediment loss, and nutrient depletion are widespread, with fertile soil washed into rivers such as the Gibee and Awash (Alemayehu and Birhanu 2018; Bachie and Burayu 2024).

5.3. Climate Change Impacts

Increasing temperatures, erratic rainfall, and prolonged droughts have devastated crops and livestock (Mekonnen and Getachew 2020). In Borana alone, more than 2.8 million cattle have died in recent droughts, with severe famine affecting hundreds of thousands (GemedoDalle et al. 2006). Dugassa et al. (2021) argues that if the change in climate is not curtailed, it may cause a significant damage to the agricultural production in Oromia and along the Nile basins. Climate variability intensifies existing pressures. Droughts, soil degradation, and biodiversity loss undermine both agrarian and pastoral livelihoods (Dugassa 2025). Indigenous institutions remain resilient but strained and may face erosion from external forces.

5.4. Limited Mechanization

Traditional ploughs, hand tools, and labor-intensive practices limit productivity and hinder adaptation to climate stressors (Bonger et al. 2004). Fertilizer misuse on steep slopes contributes to runoff and water contamination (Tesfaye and Woldeamanuel 2014). Across these diverse bodies of literature, several unifying themes emerge: (a) Indigenous systems are ecologically grounded and socially integrative. They link land use, ethics, governance, and food systems into a coherent whole, (b) Modernization has fragmented these systems. State farms, commercial agriculture, resettlement, and market liberalization have reduced community control over land and resources, (c) Climate variability intensifies existing pressures. Droughts, soil degradation, and biodiversity loss undermine both agrarian and pastoral livelihoods. Taken together, these works reveal a coherent narrative: indigenous Oromo systems—whether agrarian, pastoral, ethical, or governance-related—constitute a holistic socio-ecological framework that historically sustained both people and landscapes. Modern state interventions, market pressures, and climate change have disrupted this framework, leading to environmental degradation, food system erosion, and weakened adaptive capacity. Yet the persistence of Gadaa institutions, environmental ethics, and community-based conflict resolution demonstrates that local people’s knowledge remains a vital resource for building sustainable, culturally grounded development pathways.

6. Pathways to Sustainable and Climate-Resilient Agriculture: Integrating Indigenous Knowledge and Modern Agronomy

6.1. Soil Conservation and Erosion Control

Traditional Oromo land stewardship practices can be strengthened through modern terracing, contour systems, and conservation tillage have proven effective in reducing soil erosion and improving soil structure (Mekuria and Aynekulu 2013). Zero-till systems reduce soil disturbance and evaporation, making them suitable for hillside farming (Downey and Martin 2001).

6.2. Diversified Cropping Systems

Modernizing Oromo Polyculture and intercropping with modern approaches can enhance resilience by reducing pest pressure, improving soil fertility, and minimizing total crop failure under extreme weather (Altieri 2004).

6.3. Agroforestry and Integrated Systems

Oromo traditional Agroforestry practices—including alley cropping, Silvopasture, and multipurpose tree planting—can be optimized with modern technology and integrated cropping to improve soil organic matter, diversify income, and reduce pressure on natural forests (Nair 2012; FAO 2017). Species such as Sesbania, moringa, olives, and figs offer rapid biomass accumulation and soil benefits (Asfaw and Agren 2007).

6.4. Soil Fertility Management

Legume-based rotations, cover cropping, and composting improve soil structure and nutrient cycling (Pretty 2008). These practices align with traditional Oromo soil management strategies (Yosef and Asmamaw 2015).

6.5. Water Use Efficiency and Drought-Tolerant Crops

Improving water productivity is essential in drought-prone regions. C4 crops such as sorghum offer high drought tolerance and efficient water use (Abate 2016). Quinoa provides additional resilience and nutritional benefits (Altieri 2004).

6.6. Forage Innovations

Cut-and-carry forage systems reduce overgrazing and support livestock during drought (GemedoDalle et al. 2006). Forage sorghum and sorghum-Sudan grass hybrids provide high biomass with fewer irrigations (Abate 2016). Many African origin forages such as Sudan grass (Bachie et al. 2024), Bermuda and Rhodes grass (Bachie 2019) can be good fit for environmentally challenging conditions of Oromia as they are also resilient and remain productive even in the hot and dry low desert region of California.

6.7. Mechanization and Modern Tools

Small tractors and energy-efficient technologies can significantly improve labour efficiency and reduce soil degradation compared to ox-drawn ploughs (Bonger et al. 2004).

7. Lessons from the Imperial Valley, California

Although ecological and socioeconomic conditions differ substantially, agricultural development in this region illustrates the transformative role of irrigation governance and infrastructure. While a direct application of the advanced water use technology to a developing region is not easy, the Imperial Valley of California offers an opportunity of learning how irrigation can transform arid landscapes into highly productive agricultural region. With about 3 million acre-feet of Colorado River water delivered through the All-American Canal, the region supports intensive crop and forage production despite desert conditions (Rosenberg et al. 2008). Oromia’s extensive river systems offer similar potential for year-round irrigation if supported by infrastructure investment, governance reforms, and community-based water management (Seyoum and Birhanu 2019; Bachie and Burayu 2024).

Farming methods directly affect the quality of harvested food, which in turn shapes transportation, storage, and ultimately the quality of food consumed. Dietary intake, influenced by both the quality and quantity of food, is fundamental to human health and disease resistance. Public health literature identifies food security as one of the key social determinants of health. The following section examines how indigenous Oromo farming practices impact food security and public health.

Food production and food security and implication on Public Health

Traditional Oromo farming practices emphasize intercropping, which involves cultivating multiple crops together, and the use of resilient local varieties such as xaafii, sorghum, barley, wheat, and beans (Amare et al. 2021). In contrast, climate change and the expansion of industrial agriculture have promoted monocropping, thereby restricting crop diversity and weakening ecosystem resilience (Lenin et al. 2018). The application of local knowledge to maintain agro biodiversity enables communities to secure a stable and diverse food supply. Diversified cropping systems mitigate the risk of seasonal hunger and micronutrient deficiencies, particularly among vulnerable groups such as children and pregnant women. For instance, beans provide significant amounts of protein, iron, and dietary fibre (Mosisa and Tura 2017). Women and children are especially susceptible to iron deficiency, and iron from plant sources is only effectively absorbed when sufficient vitamin C is present in the meal. Therefore, Oromo indigenous farming practices, which incorporate mixed cropping and the cultivation of fruits and vegetables, enhance food security and reduce malnutrition.

The Oromo conceptualization of health is intrinsically connected to the well-being of the ecosystem (Yineger et al. 2008). The Safuu principle articulates a moral obligation to maintain harmony with nature by respecting the boundaries between human activities and the natural environment (Leykun 2024) The Oromo indigenous framework corresponds with the human, animal, and environmental health (WHO, 2022). Indigenous agricultural practices protect forests, rivers, and wetlands, mitigate environmental degradation, safeguard pollinators such as bees, reduce the transmission of zoonotic diseases, and ensure year-round access to abundant, clean water (M. Getahun 2016).

Contemporary public health model of “One Health,” which emphasizes the interconnectedness Crop rotation and intercropping contribute to food safety and are fundamental components of Indigenous food preservation strategies. (Kuyu and Bereka 2019). The Oromo worldview prioritizes environmental stewardship, and its food preservation and seed-saving practices have been refined across generations (T. Getahun 2014). Fermented foods, such as those produced in the buddena-making process, increase the bioavailability of nutrients; specifically, fermentation enhances folate (vitamin B9) levels (Ashagrie et al. 2023). Furthermore, intercropping and crop rotation reduce the risk of infectious disease transmission to plants and humans (Boudreau 2013). Climate change intensifies social challenges, including an increased risk of food poisoning. The application of natural plant-derived protectants in grain storage reduces post-harvest losses and safeguards food from mould and mycotoxins, such as aflatoxin. Ensuring the safety and purity of stored food during climate-related droughts or floods is critical for public health and serves as a primary defence against chronic food poisoning (Dugassa et al. 2021).

Climate mitigation strategies help reduce the burden of waterborne and vector-borne diseases. Oromo indigenous agriculture employs effective soil and water conservation techniques, including terracing and traditional agroforestry, such as integrating Acacia albida trees into cropland to improve soil fertility. These approaches help prevent severe soil erosion, flash flooding, and the accumulation of stagnant water during extreme weather events or seasonal rains.

Conclusion

Oromia’s rich natural resources, deep rooted local experience, and strong agricultural heritage provide a foundation for sustainable development. Yet deforestation, land degradation, climate change, and limited modernization threaten long-term productivity. Drawing from presented reviews and analyses, seven key conclusions can be identified: (1) Oromia’s natural resources, and agricultural heritage form the basis for sustainable development and regional prosperity, (2) neglecting ecological health in agricultural policies drives deforestation, land degradation, climate change, and social challenges (3) climate change and an unsupported modernization may threaten long-term soil productivity, food security, water availability and multiply public health problems. The decline of traditional land management and replacement with villagization or re-settlement into ecologically preserved ecosystems further aggravate social problems, (4) integrating indigenous knowledge with modern agronomic innovations fosters climate-resilient, sustainable agriculture. Collaborative research between the indigenous farming experts and scientists supports knowledge exchange and production. The literature review suggests that Oromo Indigenous Knowledge constitutes an important socio-ecological resource for climate adaptation, sustainable agriculture, and food security in Oromia. Indigenous agricultural practices, environmental ethics, and governance institutions have historically contributed to resource stewardship and resilience under variable environmental conditions. However, climate change, land degradation, demographic pressures, and institutional transformation continue to undermine these systems. Rather than viewing Indigenous Knowledge and modern agricultural science as competing approaches, the evidence reviewed indicates that their integration offers promising opportunities for improving resilience, sustainability, and food-system outcomes. Future research should focus on empirical evaluation of integrated approaches and the documentation of locally adaptive practices across diverse agroecological zones of Oromia. Strategic investment, community engagement and revitalizing the Oromo indigenous farming practices can help Oromia regain food security and develop ecological balances. conservation
