Latin America Makes Headway Against Land Degradation

Two-thirds of the 33 countries of Latin America and the Caribbean have already submitted or are preparing to submit to the United Nations their land degradation goals, to combat a problem that threatens agriculture and the lives of their people.

In 2015, the parties to the United Nations Convention to Combat Desertification (UNCCD) agreed to combat desertification and restore degraded land and soil, with national goals, which are based on the level of erosion in each country and which aim to achieve Land Degradation Neutrality (LDN) by 2030.

“What we are doing directly now is to establish a policy of neutral land management. That is, where I degrade, on the other hand I compensate. We cannot continue with these extractive policies in the countries where what is degraded is never given back to the earth,” José Miguel Torrico, the UNCCD coordinator for the region, who is based in Chile, told IPS.

The new commitment, he stressed, is that “What one takes from the earth, one puts back, to maintain its productivity.”

The concept of LDN is defined as “a state whereby the amount and quality of land resources, necessary to support ecosystem functions and services and enhance food security, remains stable or increases within specified temporal and spatial scales and ecosystems.”

“Today we are in the process of setting targets to achieve land neutrality. This is happening in 22 countries of the region that are actively taking part. Some have already established their goals and others, like Brazil, are at the end of the process of setting them,” Torrico said.

According to figures from UNCCD, there are currently more than two billion hectares of degraded land in the world (an area greater than South America), which have the potential for land rehabilitation and forest restoration. Of that total, 14 percent is within the region.

Sally Bunning, Senior Policy officer of Agricultural Systems, Land and Water of the FAO Regional Office for Latin America and the Caribbean, told IPS that “degraded lands represent more than one-fifth of the forests and agricultural lands of Latin America and the Caribbean.”

“Commercial agriculture is a key driver (of that degradation), especially production of meat, soy and palm oil,” she said at the regional office in Santiago.

The expert explained that “the main areas of farmland that are facing multiple pressures include, but are not limited to, dry lands in northeastern Brazil, areas of agricultural expansion in the area of the Argentine Chaco, central Chile, farmland in southern Mexico, and parts of Cuba and Haiti.”

Bunning explained that desertification “accelerates with overgrazing as well as the growth of demand for meat and other agricultural products such as soy, sugar and cotton worldwide.”

“It is estimated that in Latin America most of the degraded lands were degraded due to deforestation (100 million hectares) and overgrazing (70 million hectares). The increase in international demand encourages farmers and large landowners to deforest in order to extend their agricultural areas and pastures for livestock farming,” she said.

According to the FAO regional official, addressing the problem is crucial “to manage the livestock sector and limit the complete elimination of the original vegetation to replace it with crops.”

“In South America, urgent action is needed in the Gran Chaco, an area that covers four countries: Paraguay, Argentina, Bolivia, and to a lesser degree Brazil,” Bunning said.

“More than half of the territory in Argentina and Paraguay are affected by problems of desertification presenting a net loss of 325,000 hectares of forest per year in Paraguay, and 45 percent and 43 percent of the loss of forests were respectively caused by the expansion of pastures and the expansion of land for commercial crops in Argentina,” she said.

Torrico recalled, in turn, that several countries “have been hit very hard by climate phenomena. For example, the El Niño phenomenon affected them seriously and there have been very severe droughts in what has to do with the degradation of soils, but also with the effects suffered by the population.”

According to the UNCCD regional coordinator, Latin American small farmers are directly affected because they have less water for their crops and in some extreme cases they are forced to migrate.

He added that desertification is closely associated with migration, noting as an example that 80 to 90 percent of migrants from Africa are a visible effect of desertification. Continue reading the IPS article in English  or  Spanish .
