ECONOMIC ACTIVITIES
Hunting and gathering and pastoralism are two distinct subsistence strategies that have shaped human societies for millennia.
Hunting and gathering
- Lifestyle: Hunters and gatherers are nomadic or semi-nomadic, moving seasonally to follow the availability of resources. They rely on wild plants and animals for food, clothing, and shelter.
- Hunting involves tracking, stalking, and trapping animals, while gathering involves collecting edible plants, fruits, nuts, and insects.
- Hunter-gatherer societies are typically small and egalitarian, with decision-making by consensus
- Relies on simple tools and weapons crafted from natural materials for hunting and gathering
- Since food sources are dependent on nature, there is generally little to no surplus, and societies have a direct dependency on their environment.
- Examples: The Hadza people of Tanzania, the Ju/'hoansi people of the Kalahari Desert, the Sentinelese people of the Andaman Islands.

Pastoralism
- Lifestyle: Pastoralists are nomadic or semi-nomadic, herding domesticated animals such as sheep, goats, cattle, or camels. They rely on their animals for food, milk, wool, leather, and transportation
- Pastoralists move their herds to find fresh grazing land and water. They may also supplement their diet with hunting and gathering.
- Pastoralist societies can be more complex than hunter-gatherer societies, with social stratification and leadership roles
- Pastoral societies can be either sedentary or semi-nomadic, depending on the availability of grazing land for their herds.
- Often organized around kinship and the management of herds, with a focus on the well-being and reproduction of livestock
- Nomadic pastoralists may move their herds in search of better grazing during different seasons
- Examples: The Maasai people of East Africa, the Bedouin people of the Middle East, the Fulani people of West Africa

Nomadic herding, also known as pastoral nomadism, is a subsistence strategy and way of life that involves the constant movement of a community along with their livestock in search of fresh pasture and water. This form of livelihood is primarily associated with the raising of animals for various products, such as milk, meat, and hides. Nomadic herding is often practised in arid or semi-arid regions where the availability of grazing land is limited and unpredictable.
Key Characteristics of Nomadic Herding:
- The primary focus is on raising and managing livestock, which may include sheep, goats, cattle, camels, and other animals adapted to the local environment.
- Nomadic herders move with their animals in response to seasonal changes in weather and the availability of pasture. During the dry season, they may move to areas with better water sources, while in the wet season, they might return to areas with lush grazing lands
- Nomadic societies often have flexible social structures that can adapt to the needs of the community. Leadership may be based on knowledge of the land, herding skills, or other practical abilities
- Nomadic herders typically live in portable and temporary dwellings, such as tents or yurts, which can be easily assembled and disassembled as the community moves
- Nomadic herding communities aim to be self-sufficient, relying on their livestock for food, clothing, and other essential resources. They may engage in limited agriculture, trade, or other activities when settling in one place for a period
- Nomadic herding communities often develop unique cultural practices and traditions, closely tied to their nomadic lifestyle and dependence on animals.
- Animals like sheep, goats, cattle, or camels are central to their lives. They provide food (meat, milk), clothing (wool, leather), transportation, and even fuel (dung).
- Commercial livestock rearing is conducted on a large scale, often involving thousands or even millions of animals. This scale allows for economies of scale and increased production efficiency.
- Animals are typically raised in confined spaces, such as feedlots, barns, or cages, to maximize control over their environment and feeding. This intensive management approach aims to optimize growth rates and production efficiency
- Farms often specialize in the production of a specific type of livestock, such as beef cattle, dairy cows, broiler chickens, or egg-laying hens. Specialization allows for the application of tailored management practices and technology
- Commercial livestock operations heavily rely on technology and automation. This includes automated feeding systems, climate control in enclosed facilities, genetic selection for desirable traits, and the use of veterinary pharmaceuticals
- Animals are raised with a focus on efficient feed conversion, aiming to produce more meat, milk, or eggs with less feed input. This is achieved through selective breeding, nutritional management, and the use of growth-promoting additives
- Selective breeding is employed to develop animal breeds with desirable traits, such as high growth rates, improved feed conversion efficiency, disease resistance, and product quality
- Commercial livestock rearing is driven by market demands. The goal is to produce animal products for sale in local, national, or international markets. Farms often respond to consumer preferences and market trends
- Concerns about the environmental impact of commercial livestock rearing include issues such as waste management, water usage, and greenhouse gas emissions. Efforts are made to implement sustainable practices and mitigate environmental impacts
Subsistence agriculture is a farming practice primarily aimed at producing enough food to meet the basic needs of a household or community, with little or no surplus for sale or trade. In subsistence agriculture, the primary goal is to ensure the survival and sustenance of the farming family rather than generating income or surplus products for the market. This form of agriculture is often associated with small-scale and traditional farming methods.
Key Characteristics of Subsistence Agriculture:
- Subsistence farming is typically characterized by small landholdings and limited resources. Families or communities work on their own plots of land using manual labor and simple tools
- Subsistence farmers often grow a variety of crops to ensure a balanced diet and reduce the risk of crop failure due to pests, diseases, or adverse weather conditions. This practice is known as polyculture
- Subsistence agriculture generally involves low levels of mechanization and technology. Farming tools are often simple and may include hand tools, such as hoes and plows pulled by animals
- Family members are actively involved in the farming process, contributing manual labor for planting, cultivation, and harvesting. In some cases, communities may engage in communal labor-sharing practices
- The primary goal is to produce enough food to meet the nutritional needs of the farming family or community. Surplus production, if any, is minimal and is often used for barter or local exchange
- Subsistence agriculture tends to rely on traditional and time-tested farming methods that are adapted to local environmental conditions. Crop rotation and intercropping are common practices
- Subsistence farmers typically have limited access to markets, and their production is primarily for personal consumption. Cash crops and market-oriented agriculture are less common in subsistence farming
- Many subsistence farmers depend on natural rainfall for irrigation rather than using advanced irrigation systems. This reliance on weather conditions can make agriculture vulnerable to climate variability
Types of Subsistence Agriculture:
-
Slash-and-Burn Agriculture: Also known as shifting cultivation, this method involves clearing a plot of land, burning vegetation, and then planting crops. After a few years, the plot is abandoned, and a new one is cleared.
-
Intensive Subsistence Agriculture: In densely populated regions, farmers practice intensive subsistence agriculture, cultivating small plots of land intensively to maximize yield per unit of land.
-
Pastoral Nomadism: Some nomadic communities rely on subsistence agriculture by herding animals for meat, milk, and other products. They may move with their herds to find suitable grazing areas.
-
Mixed Farming: Combining crop cultivation with livestock rearing is common in subsistence agriculture. Animals provide additional resources such as milk, meat, and manure.
- Subsistence agriculture often yields lower production per unit area compared to modern, commercial farming methods
- Because subsistence farmers produce primarily for their own consumption, they may be vulnerable to food shortages during periods of crop failure or other challenges
- Many subsistence farmers face economic challenges and may lack access to credit, markets, and technology, contributing to persistent poverty
- Traditional farming practices, such as slash-and-burn agriculture, can lead to deforestation and soil degradation if not managed sustainably.
- Subsistence farmers are often highly vulnerable to the impacts of climate change, such as changes in precipitation patterns, temperature extremes, and increased frequency of extreme weather events
Primitive subsistence agriculture, also referred to as traditional or primitive farming, represents early and basic forms of agricultural practices developed by human societies thousands of years ago. This type of agriculture involves simple techniques and tools, with the primary goal of meeting the basic food needs of a family or community. Primitive subsistence agriculture laid the foundation for more advanced agricultural practices that emerged as civilizations developed.
Key Characteristics of Primitive Subsistence Agriculture:
