The geography of food is a field of human geography. It focuses on patterns of food production and consumption on the local to global scale. Tracing these complex patterns helps geographers understand the unequal relationships between developed and developing countries in relation to the innovation, production, transportation, retail and consumption of food. It is also a topic that is becoming increasingly charged in the public eye. The movement to reconnect the 'space' and 'place' in the food system is growing, spearheaded by the research of geographers.
Spatial variations in food production and consumption practices have been noted for thousands of years. In fact, Plato commented on the destructive nature of agriculture when he referred to the soil erosion from the mountainsides surrounding Athens, stating "[In previous years] Athens yielded far more abundant produce. In comparison of what then was, there are remaining only the bones of the wasted body; all the richer and softer parts of the soil having fallen away, and the mere skeleton of the land being left". Societies beyond those of ancient Greece have struggled under the pressure to feed expanding populations. The people of Easter Island, the Maya of Central America and most recently the inhabitants of Montana have been experiencing similar difficulties in production due to several interconnecting factors related to land and resource management. These events have been extensively studied by geographers and other interested parties (the study of food has not been confined to a single discipline, and has received attention from a huge range of diverse sources).[ citation needed ]
Modern geographers initially focused on food as an economic activity, especially in terms of agricultural geography. It was not until recently that geographers have turned their attention to food in a wider sense: "The emergence of an agro-food geography that seeks to examine issues along the food chain or within systems of food provision derives, in part, from the strengthening of political economy approaches in the 1980s". [1]
Food has received attention from both the physical sciences and the social sciences because it is a bridge between the natural and social worlds. Some of the earliest numerical data about food production come from bureaucratic sources linked to the ancient civilizations of Ancient Egypt and the Roman Empire. Traders have also been influential in documenting food networks. Early Indian merchants and traders mapped the location of trading posts associated with food production nodes.[ citation needed ]
Food production was the first element of food to receive extensive attention from geographers in the field of cultural geography, particularly in agricultural geography.[ citation needed ]
Globally, the production of food is unequal. This is because there are two main components involved in sustenance production that are also distributed irregularly. These components are the environmental capacity of the area, and the human capacity. Environmental capacity is its ability ‘to accommodate a particular activity or rate of an activity without unacceptable impact’. [2] The climate, soil types, and availability of water affect it. Human capacity, in relation to food production, is the size of the population and the amount of agricultural skill within that population. When these two are at ideal levels and partnered with financial capital, the creation of intense agricultural infrastructure is possible, as the Green Revolution clearly portrays.[ citation needed ]
Simultaneously, the ability of a country to produce food is being severely impacted by a plethora of other factors:
Pests are becoming resistant to pesticides, or pesticides may be killing off the useful and necessary insects. [3] Examples of this happening occur around the globe. Tanzania experienced a particularly horrible infection of armyworms in 2005. At the infections peak, there were over 1000 larva per square meter. In 2009, Liberia experienced a state of emergency when invading African armyworm caterpillars began what became a regional food crisis. The caterpillars traveled through 65 towns and 20 000 people were forced to leave their homes, markets, and farms. [4] Losses like this can cost millions to billions, depending on size and duration, and have severe effects on food security. The FAO has created an international team, the Plant Production and Protection Division, which is attempting to ‘reduce reliance on pesticides’ and ‘demonstrate that pesticide use often can be reduced considerably without affecting yields or farmer profits' [5] in these, and other hard-struck areas.
Water stress, desertification, and erosion are leading to loss of arable land. [6] Agricultural practices use the bulk of the Earth’s fresh water – up to 70 percent – and those numbers are predicted to rise by 50-100 percent by 2025’. [7] Countries are being forced to divert more water than ever before to irrigate their land. Hydroelectric dams and mega-canal projects are becoming the new standard for countries like Egypt that can no longer depend on rainfall or natural flood cycles. These water shortages are also causing a source of conflict between neighboring nations as they live with increasingly high levels of water scarcity. Policy responses to these events could be implemented in order to strengthen the socio-economic growth, human health statuses, and environmental sustainability of these areas. Combining current limitations with water and transitions from practices such as agroforestry and shifting cultivation makes land susceptible to aeolian erosion by weakening soil composition and exposing larger areas of land to destructive wind. [8] Aeolian erosion largely effects deserted areas, reducing air quality, polluting water sources, and limiting fertility of nearby land.[ citation needed ]
Climate change is creating more extreme weather patterns, and agricultural practices are estimated to cause from 10 to 12 percent of greenhouses gas emissions. [9] Warming will increase the previously mentioned rates of desertification and insect activity and agricultural zones near the equator may be lost. However, due to the uneven warming that will probably occur, higher latitudes are expected to warm up at faster rates than other areas of the globe. [10] Scientists are now presenting the idea that areas in Canada and Siberia may become suitable for farming at the industrial scale, and that those areas will be able to account for any farmland that is lost at the equator. Conservative estimates place the shift of traditional crops (maize, grain, potatoes) northward at 50 to 70 kilometers a decade. It is also believed that non-traditional crops (berries, sunflowers, melons) could be established on the southern sides of these countries. [11] Changes in climate may force humans to adapt, adopt new practices, and alter old habits to promote success in the uncertain age of climate change ahead.[ citation needed ]
Criticisms of the industrialized food system regarding its inability to provide nutritious, ecologically sound, equitable food for the world's population has increased in recent history. Systems that are currently in place focus on providing relatively cheap food to millions, but often cost the Earth in terms of water and soil degradation, local food insecurity, animal welfare, rising obesity and health-related problems, and declining rural communities. Variations in diet and consumption practices on global and regional scales became the focus of geographers and economists with the vastly expanding population and widely publicized famines of the 1960s, and the food riots of 2007-2008 in 60 different countries. Due in part to these events, differences in the caloric intake of food and the composition of an average diet have been estimated and mapped for many countries since the 1960s.[ citation needed ]
Canada, USA, and Europe consume the highest amount of calories with an average per capita consumption of around 3400 calories daily. [12] The recommended daily caloric intake for men and women living in these areas is 2500 and 2000 respectively. Studies focused on consumption patterns in these areas lay the blame for increased caloric intake on soft drink and fast food consumption, and decreased physical activity. [13] Many developing countries are beginning to follow the leaders in rising caloric intake as they develop further due to increased availability of these high-impact items. Ballooning weight and associated health problems such as high blood pressure, high cholesterol, heart problems, and diabetes are being recorded in skyrocketing numbers. [14]
Globally, consumption is still extremely uneven, with areas such as Sub-Saharan Africa still having some of the lowest rates of caloric intake per capita, often falling below the recommended levels. Much of this is due to lack of access of particular foods, which is a leading factor as to why much of the undernourished population is located in this region. In the world today, there are over 800 million people that are undernourished. [15] The Democratic Republic of Congo holds the lowest average, at 1800 calories daily; however, averages do not represent the range of inequality between the best and worst fed people within a region. [16] Currently, steps are being made to reduce caloric inequality. In parts of South Africa, the government has implemented a widespread electrification system featuring a free electricity allowance due to a study was conducted from 1991 to 2002 that found a positive increase in consumption habits within villages if given access to electricity. Access to electricity allowed for less time to be spent on menial tasks such as gathering firewood, and more time working on higher-level tasks that could increase income. In fact, villages often exceeded their electrical allowances. [17]
Agriculture encompasses crop and livestock production, aquaculture, fisheries, and forestry for food and non-food products. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. While humans started gathering grains at least 105,000 years ago, nascent farmers only began planting them around 11,500 years ago. Sheep, goats, pigs, and cattle were domesticated around 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. In the 20th century, industrial agriculture based on large-scale monocultures came to dominate agricultural output.
The calorie is a unit of energy that originated from the caloric theory of heat. The large calorie, food calorie, dietary calorie, or kilogram calorie is defined as the amount of heat needed to raise the temperature of one liter of water by one degree Celsius. The small calorie or gram calorie is defined as the amount of heat needed to cause the same increase in one milliliter of water. Thus, 1 large calorie is equal to 1000 small calories.
Soil retrogression and degradation are two regressive evolution processes associated with the loss of equilibrium of a stable soil. Retrogression is primarily due to soil erosion and corresponds to a phenomenon where succession reverts the land to its natural physical state. Degradation is an evolution, different from natural evolution, related to the local climate and vegetation. It is due to the replacement of primary plant communities by the secondary communities. This replacement modifies the humus composition and amount, and affects the formation of the soil. It is directly related to human activity. Soil degradation may also be viewed as any change or ecological disturbance to the soil perceived to be deleterious or undesirable.
Good agricultural practice (GAP) is a certification system for agriculture, specifying procedures that must be implemented to create food for consumers or further processing that is safe and wholesome, using sustainable methods. While there are numerous competing definitions of what methods constitute good agricultural practice, there are several broadly accepted schemes that producers can adhere too.
Sustainable agriculture is farming in sustainable ways meeting society's present food and textile needs, without compromising the ability for current or future generations to meet their needs. It can be based on an understanding of ecosystem services. There are many methods to increase the sustainability of agriculture. When developing agriculture within sustainable food systems, it is important to develop flexible business processes and farming practices. Agriculture has an enormous environmental footprint, playing a significant role in causing climate change, water scarcity, water pollution, land degradation, deforestation and other processes; it is simultaneously causing environmental changes and being impacted by these changes. Sustainable agriculture consists of environment friendly methods of farming that allow the production of crops or livestock without causing damage to human or natural systems. It involves preventing adverse effects on soil, water, biodiversity, and surrounding or downstream resources, as well as to those working or living on the farm or in neighboring areas. Elements of sustainable agriculture can include permaculture, agroforestry, mixed farming, multiple cropping, and crop rotation.
Conservation agriculture (CA) can be defined by a statement given by the Food and Agriculture Organization of the United Nations as "Conservation Agriculture (CA) is a farming system that can prevent losses of arable land while regenerating degraded lands.It promotes minimum soil disturbance, maintenance of a permanent soil cover, and diversification of plant species. It enhances biodiversity and natural biological processes above and below the ground surface, which contribute to increased water and nutrient use efficiency and to improved and sustained crop production."
Urban agriculture refers to various practices of cultivating, processing, and distributing food in urban areas. The term also applies to the area activities of animal husbandry, aquaculture, beekeeping, and horticulture in an urban context. Urban agriculture is distinguished from peri-urban agriculture, which takes place in rural areas at the edge of suburbs.
Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable. The environmental degradation process amplifies the impact of environmental issues which leave lasting impacts on the environment.
Soil conservation is the prevention of loss of the topmost layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination.
Human impact on the environment refers to changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans. Modifying the environment to fit the needs of society is causing severe effects including global warming, environmental degradation, mass extinction and biodiversity loss, ecological crisis, and ecological collapse. Some human activities that cause damage to the environment on a global scale include population growth, neoliberal economic policies and rapid economic growth, overconsumption, overexploitation, pollution, and deforestation. Some of the problems, including global warming and biodiversity loss, have been proposed as representing catastrophic risks to the survival of the human species.
Environmental vegetarianism is the practice of vegetarianism that is motivated by the desire to create a sustainable diet, which avoids the negative environmental impact of meat production. Livestock as a whole is estimated to be responsible for around 15% of global greenhouse gas emissions. As a result, significant reduction in meat consumption has been advocated by, among others, the Intergovernmental Panel on Climate Change in their 2019 special report and as part of the 2017 World Scientists' Warning to Humanity.
Worldwide more human beings gain their livelihood from agriculture than any other endeavor; the majority are self-employed subsistence farmers living in the tropics. While growing food for local consumption is the core of tropical agriculture, cash crops are also included in the definition.
The environmental impacts of animal agriculture vary because of the wide variety of agricultural practices employed around the world. Despite this, all agricultural practices have been found to have a variety of effects on the environment to some extent. Animal agriculture, in particular meat production, can cause pollution, greenhouse gas emissions, biodiversity loss, disease, and significant consumption of land, food, and water. Meat is obtained through a variety of methods, including organic farming, free-range farming, intensive livestock production, and subsistence agriculture. The livestock sector also includes wool, egg and dairy production, the livestock used for tillage, and fish farming.
Deforestation in Nigeria refers to the extensive and rapid clearing of forests within the borders of Nigeria. This environmental issue has significant impacts on both local and global scales.
The term food system describes the interconnected systems and processes that influence nutrition, food, health, community development, and agriculture. A food system includes all processes and infrastructure involved in feeding a population: growing, harvesting, processing, packaging, transporting, marketing, consumption, distribution, and disposal of food and food-related items. It also includes the inputs needed and outputs generated at each of these steps. Food systems fall within agri-food systems, which encompass the entire range of actors and their interlinked value-adding activities in the primary production of food and non-food agricultural products, as well as in food storage, aggregation, post-harvest handling, transportation, processing, distribution, marketing, disposal, and consumption. A food system operates within and is influenced by social, political, economic, technological and environmental contexts. It also requires human resources that provide labor, research and education. Food systems are either conventional or alternative according to their model of food lifespan from origin to plate. Food systems are dependent on a multitude of ecosystem services. For example, natural pest regulations, microorganisms providing nitrogen-fixation, and pollinators.
The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. The environmental impact of agriculture varies widely based on practices employed by farmers and by the scale of practice. Farming communities that try to reduce environmental impacts through modifying their practices will adopt sustainable agriculture practices. The negative impact of agriculture is an old issue that remains a concern even as experts design innovative means to reduce destruction and enhance eco-efficiency. Though some pastoralism is environmentally positive, modern animal agriculture practices tend to be more environmentally destructive than agricultural practices focused on fruits, vegetables and other biomass. The emissions of ammonia from cattle waste continue to raise concerns over environmental pollution.
Agricultural pollution refers to biotic and abiotic byproducts of farming practices that result in contamination or degradation of the environment and surrounding ecosystems, and/or cause injury to humans and their economic interests. The pollution may come from a variety of sources, ranging from point source water pollution to more diffuse, landscape-level causes, also known as non-point source pollution and air pollution. Once in the environment these pollutants can have both direct effects in surrounding ecosystems, i.e. killing local wildlife or contaminating drinking water, and downstream effects such as dead zones caused by agricultural runoff is concentrated in large water bodies.
At the global scale sustainability and environmental management involves managing the oceans, freshwater systems, land and atmosphere, according to sustainability principles.
Costa Rican agriculture plays a profound part in the country's gross domestic product (GDP). It makes up about 6.5% of Costa Rica's GDP, and 14% of the labor force. Depending upon location and altitude, many regions differ in agricultural crops and techniques. The main exports include: bananas, pineapples, coffee, sugar, rice, vegetables, tropical fruits, ornamental plants, corn, potatoes and palm oil.
Soil governance refers to the policies, strategies, and the processes of decision-making employed by nation states and local governments regarding the use of soil. Globally, governance of the soil has been limited to an agricultural perspective due to increased food insecurity from the most populated regions on earth. The Global Soil Partnership, GSP, was initiated by the Food and Agriculture Organization (FAO) and its members with the hope to improve governance of the limited soil resources of the planet in order to guarantee healthy and productive soils for a food-secure world, as well as support other essential ecosystem services.
