What are the factors that affect biodiversity

There are geographical, political, ecological and socioeconomic factors capable of conditioning and modifying the balance of ecosystems and the anthropic pressures they support.

If you are wondering what factors affect the ecosystem, acting as generators of changes in biodiversity, consult this AgroCorrn article on what factors affect biodiversity , in which you can also discover some biodiversity conservation strategies to avoid that it continues to be lost in enormous quantities.

Overexploitation of the natural environment

The rate of natural resource extraction practices exceeding their capacity over time to renew themselves, gives rise to one of the great threats to the natural environment : the overexploitation of natural resources .

The growing demand for resources, driven by the growth of the human population worldwide, together with the globalization of economic and consumption systems, has led to the incorporation of technological advances in order to improve and increase productivity. As a result, the natural environment is exploited beyond its capacity for renewal, which constitutes a threat to biodiversity .

Loss, degradation and fragmentation of habitats

In addition to overexploitation, if we ask ourselves what threat to biodiversity it is essential to talk about the loss, degradation and fragmentation of habitats and their causes.

Deforestation , driven by changes in land use -for the development of agricultural activities, the installation of infrastructures and other constructions- is the main reason for the degradation of habitats. However, the following also stand out as driving forces for change:

  • The inappropriate use of the natural environment.
  • Overgrazing.
  • Overwatering.
  • The overexploitation of aquifers and other resources.
  • Droughts and other effects of climate change, which only aggravate the processes of desertification and land degradation.

On the other hand, the fragmentation of the territory , also marked by changes in land use to establish crops, roads and cities, with the loss of habitats, represents one of the greatest threats to biodiversity .

Another factor affecting biodiversity today is global pollution. For example, the processes of contamination by microplastics and organic waste and discharges raise great concerns in the scientific community and in those who work directly with the resources and services that ecosystems provide. Effects derived from pollution are increasingly visible , such as: eutrophication of aquatic ecosystems , the proliferation of harmful algae (red tides stand out), the presence of photochemical smog in cities and the increase in atmospheric temperature and surface water of seas and oceans.

All these environmental pollution problems affect biodiversity and the ecosystems that all living things inhabit. If you want to discover more, here we talk about How pollution affects the environment .

Introduction of invasive species

The introduction of invasive alien species is one of the major causes of biodiversity loss , worldwide. There are catalogs, strategies and plans in order to control and have a more complete knowledge of those species that, for different reasons, have established themselves in ecosystems other than their origin. The invasion and illegal trafficking of species are closely linked, and species such as the red crab ( Procambarus clarkii ) stand out.

Effects of climate change

In the aquatic environment, it is worth mentioning the acidification of the waters and the increase in surface temperature , which cause changes in population dynamics, in their reproduction and feeding patterns.

In the terrestrial environment, the aridization of the territory is notable, influenced by a greater scarcity of rainfall, giving rise to a continuous change in ecosystems and a loss of the biodiversity they harbor.

How to take care of biodiversity

Once the factors that influence biodiversity have been exposed , a series of biodiversity conservation strategies are shown in relation to these :

  • Within the framework of desertification, implementing plant cover to achieve the protection and fixation of soils, which is tolerant to extreme arid conditions, is a strategy for adaptation to climate change, contemplated in the National Plan of Priority Actions in the field of Hydrological-forest restoration, erosion control and fight against desertification (PNAP).
  • To combat eutrophication processes: aeration or removal of hypolimnion, exposure of sediments to air, removal of sediments, creation of artificial wetlands, biomanipulation, etc.
  • In order to reverse the increasing acidification of water bodies, the limming method stands out, which consists of the addition of bicarbonate in lakes, banks or banks.
  • To eliminate contamination, phytoremediation or the use of plants that incorporate and accumulate different pollutants such as heavy metals in their body are very common.
  • To restore seagrass beds and reefs, transplants or artificial cultivation can be carried out. In addition, it is also important to indicate with information panels the importance of phanerogams such as Posidonia oceanica and how harmful it is to remove plant berms.
  • The wildlife crossings and urban gardens are alternatives to mitigate the anthropic pressures derived from the fragmentation of the territory.

For all these measures to be effective and prevent the loss of biodiversity , it is necessary to promote cooperation between scientists, technicians, politicians and the public itself and raise awareness in society. In this sense, information and visibility campaigns on environmental problems and species that are seeing their populations diminish as a result of the activities we carry out are particularly relevant. For more information, we encourage you to read this other AgroCorrn article on Biodiversity Conservation: what it is, practices and importance .
