NEW! Social media cards and poster on soil salinization!

Salt-affected Soils: A global concern reducing agricultural productivity

Soils  affected by salinity and sodicity undergo a rapid decline of health, losing their capacity for biomass production, natural filtration, carbon sequestration and other necessary ecosystem functions.

Global Symposium on Salt-affected Soils

This high-level science-policy meeting #GSAS21 “Halt soil salinization, boost soil productivity” will be held in a virtual format from 20 to 22 October 2021.

Are all salt-affected soils a threat?

The differences between naturally saline and sodic soils and human-induced salinization and sodification.

Economical losses due to soil salinization

The global annual cost of salt-induced land degradation in irrigated areas is estimated to be USD 27.3 billion related to lost crop production.

Migration due to soil salinization

As climate change and water scarcity increase, more soils become salt-affected...forcing people to leave their once productive land and migrate.

What can you do? Halt soil salinization, Boost soil productivity

Raise awareness, promote the use of sustainable farming systems, invest in gathering better knowledge...

Farmers in action

Eight good practices to halt soil salinization and boost soil productivity: Practice halophytic agriculture, irrigate with good quality water...

Soil pollution and phytoremediation

Some plants can uptake, remove and stabilize contaminants from the soil, through different mechanisms.

Impacts of soil pollution on key soil functions

Soil pollution causes a chain of degradation processes in soil, jeopardizing its ability to provide ecosystem services.

Pollution-induced changes in the functioning of soil ecosystems

Mobile soil fauna often uses an avoidance strategy, reducing the first steps of litter decomposition in heavily polluted soils. 

Economic losses due to soil pollution

Soil pollution entails direct remediation and management costs ranging from thousands to billions of dollars per year, depending on the extent and type of contaminants. 

Soil pollution jeopardizes the achievement of most of the SDGs

The prevention, control, and remediation of soil pollution are fundamental if we want to implement the 2030 Agenda for Sustainable Development.

Impact of soil contaminants on human health

Contaminants in soil have widespread effects on organs and systems, producing a wide variety of health outcomes, from acute to chronic diseases, leading to severe development issues, changes in bodily functions, and premature death.

Contaminants tranfer to the food chain

Contaminated plants and soil organisms lead to potentially hazardous accumulations in animals higher in the food web such as grazing animals, birds and ultimately transferred to humans.

Thematic factsheet

Soils store and filter water
Improving food security and our resilience to floods and droughts

Functional soils play a key role in the supply of clean water and resilience to floods and droughts. Water infiltration through soil traps pollutants and prevents them from leaching into the groundwater. Moreover, the soil captures and stores water, making it available for absorption by crops, and thus maximizing water use efficiency

Soils help to combat and adapt to climate change by playing a key role in the carbon cycle

Healthy soils provide the largest store of terrestrial carbon. When managed sustainably, soils can play an important role in climate change mitigation by storing carbon (carbon sequestration) and decreasing greenhouse gas emissions in the atmosphere.

Healthy soils are the basis for healthy food production
The most widely recognized function of soil is its support for food production

It is the foundation for agriculture and the medium in which nearly all food-producing plants grow. In fact, it is estimated that 95% of our food is directly or indirectly produced on our soils. Healthy soils supply the essential nutrients, water, oxygen and root support that our food-producing plants need to grow and flourish.

Soil is a non-renewable resource
Its preservation is essential for food security and our sustainable future

Soil is a finite resource, meaning its loss and degradation is not recoverable within a human lifespan. As a core component of land resources, agricultural development and ecological sustainability, it is the basis for food,feed, fuel and fibre production and for many critical ecosystem services. It is therefore a highly valuable natural resource, yet it is often overlooked...
