In food distribution, increasing food supply is a production problem, as it takes time for products to get marketed, and as they wait to get distributed the food goes to waste. Despite the fact that throughout all food production an estimated 20-30% of food is wasted, there have been efforts to combat this issue, such as campaigns conducted to ...
Efficiency improvements often lead to a rebound effect in which consumers use the money they save to buy more energy-intensive goods and services. [44] For example, recent technical efficiency improvements in transport and buildings have been largely offset by trends in consumer behaviour, such as selecting larger vehicles and homes. [45]
[3] For example, local food initiatives often promote sustainable and organic farming practices, although these are not explicitly related to the geographic proximity of producer and consumer. Local food represents an alternative to the global food model, which often sees food traveling long distances before it reaches the consumer. [4]
Sweet sorghum may be a promising alternative source of bioethanol, due to its tolerance of a wide range of climates. [118] Cow dung can be converted into methane. [ 119 ] There is also a great deal of research involving algal fuel , which is attractive because algae is a non-food resource, grows around 20 times faster than most food crops, and ...
In other words, efficient distribution means that redistributing goods cannot make anyone better off without making someone else worse off. (See Pareto efficiency.) The inefficiencies of production and distribution exist in all types of economies. The welfare of the people can be increased if these inefficiencies are ruled out.
Resource efficiency is the maximising of the supply of money, materials, staff, and other assets that can be drawn on by a person or organization in order to function effectively, with minimum wasted resource expenses.
First and fundamentally, independence is a matter of degree. For example, eliminating dependence on the electrical grid is relatively easy. In contrast, running an efficient, reliable food source can be a chore. Living within an autonomous shelter may also require sacrifices in lifestyle or social opportunities.
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.
