The change of the climate is on the verge and different activities associated with human, for example, urbanization, food production and industrialization are the main contributors. The production of food alone contributes to close to 25% of the emissions associated with global carbon. On the opposite, the variation of weather patterns and regular harsh weather conditions have highly contributed to climate change which has greatly affected the supply of food around the world.
Deforestation affects the production of food negatively, this means if trees are not sufficient to absorb carbon dioxide it leads to the greenhouse effect. Also, the pesticide and fertilizers that are used in crop protection have led to a decrease of the insect and the general soil fertility. This happens because microbial organisms that makes the soil fertile have also been affected making it difficult for the plants to get nutrients.
The world population is growing at a very high rate. We are expected to hit at least 9.5′ billion people by the year 2050. To act upon these anticipations, the United Nations Food and Agriculture’ Organization (FAO) is pushing for at least 60% increase on the food resources without having to increase the size of the farm land.
It is not very clear how these intensification are going to be realized. Other strategies such as organic farming are highly respected for the insect life and the soil ecology and may help towards restoration of the soil fertility.
The whole idea about the production of food is under discussion, although according to FAO, there are at least 821m individuals facing hunger strikes. An estimate that was carried out by the biologist states that’ current food production can satisfy at least 14 billion’ people. But you realize, around a third of this particular food goes into waste because of the ineffective methods of supply, unequal distribution of food and unsustainable and unhealthy diets.
Therefore, the experts in the department of food should not only put emphasis on the intensification of agriculture, but also, on the strategies that will help to change consumption patterns and avoid wastage of food. There are 3 areas where the best changes should be adopted. They include:
- Recycling of the food Waste
Consumption of food should be made circular. This therefore, means that the organic waste for example, food’ scraps should not be directed into the landfill; instead, they should be changed into biogas and compost. Currently, the organic waste is what is recycled at a lower level. With countries for example, the Netherlands and Germany leading there are those that are still behind. These are good technologies which have been invented to make the whole process easier.
The Local Energy Adventure Partnership have come up with anaerobic’ digester that is made for the urban’ context. This is a machine that will help to change the organic waste from commercial buildings or residential into biogas and compost which can help to fuel the growth of food in urban areas. Food waste needs to be treated in the right manner. They can be used as the animal fodder
- Urban Farming
This is another highly effective method to help lower down the demand for agricultural land through growing food’ around cities where it is highly needed hence reducing the distance which food has to be transported. This is aimed to enable the producers to be able to map and perfectly match the demands by the consumers easily through engaging production in areas where food is only consumed.
A good number of researches have been made on the urban agriculture and how cities can support it. It can be approached through hydroponic systems. This helps to carry out cultivation from a vertical surface. It is a principle of city planning in order to take care of land rooftops and other spaces for the growth of food.
In urban areas, it is also possible to identify innovations which are designed to simplify the urban farming and make it sustainable. For example, the Farmhouse’ is one modular housing system that utilizes vertical stacking. This enables residents to easily grow food.
- Changing Diets
This option is aimed at encouraging individuals to change diets. The uprising of people earning middle incomes is taking high quantities of cheese, meat and eggs. In China, since the year 1990, consumption of beef and poultry has greatly increased. The diet related to farm animals is very heavy on grains, which can be consumed by people more easily.
Therefore, encouraging people to eat more of meat will help reduce pressure on the food system of the world. Around cities, research institutions, governments, communities and communities should come together and pool together food’ initiatives in order to assure people healthier, more sustainable and cheaper choices, although this needs good political coexistence and organization among various levels of government.
It is very clear that every approach is associated with limited action scope when compared to strategies and the agriculture techniques which can be provided at the industrial level. With many proposals, there could be several approaches which make it highly efficient to use on already existing resources around the cities. With the above changes, effective policies on sovereignty and food justice can help towards the establishment of fair food supply’ chains and efficient distribution of the food around the world.
