1. The Human Diet ■ The human diet • Minimum caloric requirement: • 2, 700 calories for men and 2, 000 calories for women. • Diet is organized along models: • No single food can supply human needs in protein, vitamins and amino acids. • Result of the socio-economic environment of the population: • About 15 plants and 8 animal species supply 90% of food. • Commonality of some food components in different parts of the world. • Related to an average daily calorie intake. • Linked to agricultural practices, but also to agribusiness and food processing industries. • Factors: • Income (quantity, quality, meat consumption). © Dr. Jean-Paul Rodrigu

The Human Diet ■ The “Fast Food” diet • Growing involvement of corporate interests. • Higher sugar and fat content: • Value added and high profits food products. • Low satiation level. • Fast food industry: • Largest group of minimum wage workers in the US (3. 5 million). • 25% of the adult population visit a fast food restaurant every single day. • Most fast food is delivered to the restaurant already frozen, canned, dehydrated, or freeze-dried. • A fast food kitchen is merely the final stage in a vast and highly complex system of mass production. © Dr. Jean-Paul Rodrigu

1. Main Agriculture Models Subsistence farming Food mainly grown to support the family / community. Variety of plants and animals cultivated. Surpluses sold on local markets, often to pay taxes and buy simple goods. Limited level of technology and capital investment. Commercial agriculture Mostly owned by family interests (SME). Food mainly grown for local/national markets, with some exports. Specialization of crops (economies of scale). Average level of technology and capital investment. Corporate farming Food grown for global markets, but in many case regionally. Usage of subcontractors (commercial farmers). Emphasis on product development, branding and marketing. Specialized cash crops (coffee, bananas, cacao, sugar, etc. ) for plantations. Often control several elements of the supply chain (seeds, transformation). © Dr. Jean-Paul Rodrigu

Market concentration Large multinational agro-firms. Control of technical expertise (intellectual property). Retailers becoming grocers. Monoculture Improved yield. Increased dependency on fertilizers and irrigation. Biodiversity risk. Aquaculture Try to replace exhausted fish supplies. More rational use of oceanic resources.

Grown in ponds along coastal areas. Filled with saltwater pumped from the ocean. Shrimp ready for harvest in 90 to 120 days. • Ecological issues: • Some mangrove forests cleared. • Replace a diverse ecosystem with monoculture. • Waste water can be a source of pollution. © Dr. Jean-Paul Rodrigu

Consumption habits. The profit that can be derived from trading food products. Highly linked to export cultures that are produced strictly to generate income. • Third World countries are massively involved in these types of cultures. • Overcome shortages: • Import what is lacking in the national production. • An economy needs to generate sufficient surpluses from other sectors. • Purchase enough food to overcome the national deficit. • Very few Third World countries can afford to do so. © Dr. Jean-Paul Rodrigu

4.

1. The Green Revolution ■ Context • Strong population growth in the second half of the 20 th century. • New techniques were required to increase production. • New land was becoming scarce. • Labor was difficult to add to existing agricultural systems. ■ Increasing the agricultural output • Green Revolution in the 1960 s. • New varieties of wheat, corn and rice: • 1920: 20 bushels per acre (wheat). • 1997: 120 bushels per acre (wheat). • Enabling up to three harvests per year and increased outputs. © Dr. Jean-Paul Rodrigu

1. The Green Revolution ■ Strategy • Focused more on scientific achievements rather than on mechanization of agriculture. • Focused on genetics and pedology (soil science). • The development of new seed strains: • • Increase agricultural production. Make crops more resistant to diseases. Development of hybrids. New strains do not occur naturally. • The improvement of inputs into soils: • • Fertilizers of various types. Enhance the productivity of previously marginal soils. Irrigation in dry areas (40% of our food comes from irrigation). Boost productivity in many world regions but not without costs. © Dr. Jean-Paul Rodrigu

1. The Green Revolution ■ The Green Revolution and economic dependency • Agriculture is now more capital intensive: • Requires irrigation systems, fertilisers and pesticides. • Often produced by multinational corporations. • A shift from subsistence to commercial and corporate agriculture. • Consumes a lot of oil. • Financing agriculture: • Increasing linkages with financial institutions. • Borrowed money to purchase inputs, fell into debt, and lost their land to creditors when they were unable to pay. • Put the peasant in a debt cycle. • In many areas the Green Revolution increased landlessness among the peasantry. © Dr. Jean-Paul Rodrigu

1. The Green Revolution ■ Future of agriculture? • Increase in global food trade. • Price and availability remain uncertain. • Improving the performance of plants and animals: • Genetic engineering; transgenic crops (high protein potatoes). • Controlled ripening (enzyme); tomatoes have a shelf life of 10 to 14 days. • Herbicide and fungal resistance. • Animal diet (increased absorption). • Improved nutrition (more amino acids, vitamins and easier digestion). • Modifying life to suit medical, industrial and energy purposes: • Disease fighters (bananas and potatoes delivering vaccine). • Biomanufacturing (colored cotton; plastic making corn; rubber making sunflower; hydrogen producing algae. ). © Dr. Jean-Paul Rodrigu

2. Food Security and Food Aid ■ Food security • State of affairs where people have access to safe and nutritious food to maintain a healthy and active life: • Quantitatively and qualitatively adequate food (70 days). • Affordability. ■ Dimensions • Availability: • Sufficient quantities of food of appropriate quality, supplied through domestic production or imports. • Access. • Optimal uptake: • Nourishment with a sustaining diet, clean water and adequate sanitation, together with health care. © Dr. Jean-Paul Rodrigu
