The Resilience Of Agricultural Systems: For A Sustainable Agricultural Production?

The resilience of agricultural systems: for a sustainable agricultural production?

Strengthen resilience of agricultural systems: a prerequisite for sustainable agricultural production?

Today, one of the main challenges facing the agricultural sector is how to achieve sustainable agriculture that provides sufficient food and ecosystem services for current and future generations in an era of climate change, rising fuel costs, social tensions, financial instability and accelerating environmental degradation.

The challenge is compounded by the fact that the majority of the world’s arable land is under monoculture. However, because of their homogeneity, monoculture systems are particularly vulnerable to climate change and biotic stresses (exposure to fungal and bacterial diseases, etc.).

This has led many experts to suggest that agro-ecology represents a strong means of increasing the productivity and sustainability of agricultural production. Increasingly, agronomic experts agree that the performance and stability of agro-ecosystems depend largely on the level of plant and animal biodiversity present in the system and its environment.

What is the resilience of a farming system?

The resilience of a farming system is defined as its capacity to re-establish its baseline functioning in the face of economic, social and environmental shocks and stresses. The resilience of a system can be of two kinds:

  • Specific resilience: either a one-off, sudden disruption
  • General or global resilience: a disturbance against which the system must cope over the long term.

The resilience of a system thus takes into account three factors:

  • its robustness: ” the system is able to tolerate disturbances without deviating from its routine regime. For example, a dairy farm undergoing a drought can tolerate this hazard if its forage stocks are sufficient. »
  • its adaptability: ” the system is capable of implementing technical, organisational or commercial adaptations to cope with hazards and quickly return to a routine regime. For example, in order to cope with repeated droughts, diversification of crop rotation would make it possible to distribute the climatic risks over different crops and thus increase the stability of production. »
  • its transformability: ” the system is capable of profound transformation in order to endure. For example, faced with a drastic fall in the price of milk, an intensive dairy farm can evolve towards a thrifty and autonomous system that may involve changing the breed of the herd, setting up a new production workshop, changing its marketing method, etc. »

These resilience issues need to be addressed in a regional context. These farming systems work because farms, farmers’ organisations, service providers and supply chain actors are integrated into the local environments and functions of agriculture.

The resilience of agricultural systems: what interest for agroecology?

Biodiversity within systems provides various ecological services beyond food production, such as

  • recycling of nutrients,
  • regulation of the local microclimate and hydrological processes,
  • removal of unwanted organisms
  • detoxification of harmful chemicals.

As the renewal processes and ecological services provided by biodiversity are largely biological, their functioning depends on the maintenance of biological integrity and diversity in agroecosystems.

In general, natural ecosystems appear to be more stable and less subject to fluctuations in performance and populations of organisms that make up the community.

Ecosystems with greater diversity are more stable because they have greater resilience, or ability to avoid or withstand disturbances, and greater ability to recover from disturbances.

 

In systems managed according to agroecological techniques, diversified farming systems allow, among other things

  • complementary interactions that increase yields with low inputs, thereby increasing profits,
  • minimise risks through crop diversity

 

The CDA places at the heart of its missions this double objective of maintaining the diversity of the ecosystems and optimal performance of the farms. Would you like to carry out an audit of your system to optimise your production? Do not hesitate to contact us!
