Diversify or specialize? Household livestock strategies along an oasis urbanization gradient in southeastern Algeria
This study of 240 households in southeastern Algeria reveals that while livestock diversification is more common in rural areas for risk management, specialization driven by larger herd sizes yields higher economic returns, highlighting a critical trade-off between risk mitigation and income maximization as urbanization progresses.

In the vast, sun-scorched landscapes of the Sahara, where water is scarce and the heat is relentless, life has always depended on a delicate balance between people and their animals. For centuries, families in these arid regions have raised livestock not just for meat and milk, but as a living bank account and a shield against the unpredictability of climate and markets. When a drought strikes or a disease spreads, having a mix of different animals—goats that can eat tough scrub, sheep that provide wool, and chickens that lay eggs—can mean the difference between hunger and survival. This strategy of keeping a variety of species is known as diversification, and it is a cornerstone of resilience in dry places. However, as cities grow and expand into these traditional farming lands, the rules of the game change. Space becomes tight, and the nature of daily life shifts from open fields to crowded courtyards. The question facing scientists and communities alike is whether these families can continue to rely on their old strategies of mixing many animals, or if they must adapt by focusing on just one or two types that fit their new, smaller world.
A team of researchers from the University of Ouargla in southeastern Algeria set out to answer this question by looking at how family livestock farming changes as one moves from the open countryside into the heart of a growing city. They focused on the Ouargla region, an area where the climate is harsh, with annual rainfall rarely exceeding a few inches and summer temperatures soaring past forty-five degrees Celsius. Despite the rapid urbanization and the rise of modern economic activities, family farming remains a vital part of life for many households. The researchers traveled to four distinct locations to capture a full picture of this transition. They visited Sidi Khouiled and Ngoussa, which represent rural areas with plenty of land; Rouissat, a peri-urban zone where city and country life mix; and Ksar Ouargla, a dense urban center where families live in houses with limited space. In each of these four places, they interviewed sixty households that raise animals, gathering a total of 240 stories about how these families manage their herds, what they earn, and how they survive.
The researchers found that family livestock farming has not disappeared in the city; it has simply reorganized itself. In the rural areas, where space is abundant, families tend to keep a diverse mix of goats, sheep, and poultry. This variety acts as a safety net, spreading the risk so that if one type of animal suffers, the others might still thrive. The average household in these rural zones owns about nine animals, and their herds are quite varied. However, as the researchers moved closer to the city center, the picture changed. In the urban neighborhoods of Ksar Ouargla, where families live in tight quarters with small courtyards, the herds became much more specialized. Here, the diversity of species dropped significantly. The most common animal in the city was the goat, a creature well-suited to confined spaces because it requires less room and can survive on lower-quality food than sheep. While rural families might keep a flock of chickens alongside their sheep, urban families often stick to just goats or a small number of chickens, adapting their practices to the physical limits of their homes.
When the team analyzed the financial side of these operations, a surprising pattern emerged regarding the relationship between variety and money. The data showed that the size of the herd was the most powerful factor driving income. Households with more animals earned significantly more money from their livestock, regardless of where they lived. In fact, the study found that for every increase in the number of animals, the income from livestock went up. Conversely, the act of diversifying—keeping many different types of animals—was actually linked to lower income from livestock. This does not mean that having different animals is a bad idea for survival; rather, it suggests that in this specific region, where families have other sources of income like wages or agriculture, the primary goal of keeping a mixed herd is not to maximize profit, but to manage risk and ensure food security. Families with larger herds in rural areas can afford to spread their resources across different species as a form of insurance, while families in the city, constrained by space, are forced to specialize in the most efficient animal they can keep, which is often the goat.
The study also highlighted a significant role for women in these farming systems. In households where women were the primary managers of the livestock, the income generated was notably higher than in households managed by men. This finding suggests that women may be organizing their small-scale, home-based operations with a high degree of efficiency, perhaps due to the intensive care required when animals are kept in close proximity to the home. It points to a reality where women are not just helpers but are central to the economic success of family farming, even in the most constrained urban environments.
Ultimately, the research reveals that there is no single "best" way to farm livestock in the Sahara; the right strategy depends entirely on where a family lives and how much land they have access to. In the countryside, where space is available, a diverse mix of animals serves as a robust buffer against uncertainty, even if it yields slightly less cash income per animal. In the city, where space is a luxury, specialization becomes a necessity, and the focus shifts to the most productive species that can fit in a courtyard. The study concludes that policies supporting these families should not try to force everyone into the same mold. Instead, support should be tailored to the specific situation: helping rural families improve the efficiency of their larger, diverse herds, while providing urban families with tools like micro-insurance and veterinary care to protect their specialized, space-efficient operations. By understanding these distinct paths, communities can better support the families that continue to raise animals in the shadow of a rapidly changing desert world.
