Climate Change: Global Farming And Aquaculture

Deal with the Climatic Change is a challenge that follows our society for the last decade. This world issue is modifying and conditioning the nature. It is known that the glaciers are melting, the sea water level is increasing and the oceans are in a process of acidification. In the land is not better, the precipitation cycle is changing and there are dry areas becoming wetter and wetland in drought, besides all the natural hazards that are increasing in number and frequency the last few years. Nevertheless, the ecosystems are not the only affected, it also alters our life. Nature is our raw material and aliments source, among others. Thus, population’s food supply has been affected by Climate Change.

The changes on world’s water conditions

However, the aquaculture is also affected by climate change and somehow also increases it. The Food and Agriculture Organization of the United Nations (FAO) has written a document where is discussed the state of world fisheries and aquaculture (FAO, 2016). In this is explained, among other things, how climate change affects these two activities and what can be done.

The first measure proposed to do the climate change less harmful is an aquaculture zoning for the new farms studying the new area. It is important to know the weather, the course of the water frames next to it and the climatic trends. If the farm already existed, it is possible to replace it into a less exposed place. Thus, the alteration of the farm is the least possible and the most important problems will be reduced.

The other big concern is the fish health, that becomes more serious with the global warming. The increase of temperatures facilitates the transmission and frequency of some disease, so it is important to implement a good management to prevent the apparition of these (Mo et al.,

On one hand, there is the implementation of monitoring and early warning systems, and on the other hand, the improvement and innovation of the structures.

Some measures are directed to reduce the farm environmental impact as increasing efficiency of water use and water recycling. One of the biggest problems of the aquaculture in land is the extremely large amount of water used and the conditions of this when goes back to the watershed. Therefore, it is important to take less water, reuse it and try to no contaminate it to prevent the pollution of all the water stream down.

And the measure more related to the topic of the project is to increase the feeding efficiency to reduce pressure and reliance on feed resources. Most fish farms use an unsustainable method to feed their fishes though a lot of research has been done to find the most sustainable fodder. Microalgae are known as the best and more sustainable option to feed fish or crustacean in
