UNITED NATIONS, June 18 (APP): Top UN officials on Friday called for stepped up efforts to combat desertification and restore land resources as nearly 800 million people are chronically undernourished as a direct consequence of land degradation, declining soil, fertility, unsustainable water use, drought and biodiversity loss.
The desertification requires solutions to helping communities increase resilience to climate change, UN Secretary-General Ban Ki-moon said in his message to mark the World Day to Combat Desertification, whose theme this year is “Protect Earth. Restore land. Engage people.”
“The livelihoods and well-being of hundreds of millions of people are at stake,” Ban said.
Ranking among the greatest environmental challenges of the current times, desertification is a phenomenon that refers to the persistent degradation of dryland ecosystems by human activities – including unsustainable farming, mining, overgazing and clear-cutting of land, and by climate change.
The World Day, observed annually on June 17, is intended to promote public awareness of the issues of desertification and drought, and the implementation of the UN Convention to Combat Desertification (UNCCD) in those countries experiencing serious drought and/or desertification.
“Over the next 25 years, land degradation could reduce global food productivity by as much as 12 percent, leading to a 30-percent increase in world food prices,” he said.
In his message, the UN chief noted more than 50 percent of agricultural land is moderately or severely degraded, with 12 million hectares lost to production each year.
“Desertificwation, land degradation, drought and climate change are
interconnected,” he said. “As a result of land degradation and climate change, the severity and frequency of droughts have been increasing, along with floods and extreme temperatures.”
The secretary-general emphasized that without a long-term solution, desertification and land degradation will not only affect food supply but lead to increased migration and threaten the stability of many nations and regions.
“This is why world leaders made land degradation neutrality one of the targets of the Sustainable Development Goals (SDGs),” he said. “That means rehabilitating at least 12 million hectares of degraded land a year.”
One important approach towards achieving that goal is sustainable, climate-smart agriculture, Ban said. That will help communities build resilience to climate change, while also supporting mitigation by taking carbon from the atmosphere and putting it back in the soil.
“The transition to sustainable agriculture will also alleviate poverty and generate employment, especially among the world’s poorest. By 2050, it could create some 200 million jobs across the entire food production system,” the secretary-general said.
In a separate message to mark the Day, Irina Bokova, the director-general of the UN Educational, Scientific and Cultural Organization (UNESCO), underscored that desertification is a threat to both arid and non-arid regions, where land over-exploitation, including intensive farming, forest exploitation for fuel and timber and overgrazing have
turned fertile soils into sterile land.
“Extreme weather events—like droughts, winds, floods and climate disruptions—are amplifying the effects and adding new causes to the degradation cycle,” said Bokova.
“The stakes are high—this is why the goal of achieving land degradation neutrality is so important,” she said.
“This is set out in Target 15.3 of the new Sustainable Development Goals, to maintain and even improve the amount of healthy and productive land resources.”
Bokova highlighted that the UNESCO Man and the Biosphere Programme, International Hydrological Programme and Global Action Programme on Education for Sustainable Development are working to engage people in sustainable land management practices and agro-forestry, in developing green economies, in consuming responsibly, and
in restoring ecosystems.
“Desertification is not always irreversible. Land restoration is the ultimate tool, and UNESCO is determined to do everything to restore our ecosystems, as was featured during the World Congress of Biosphere Reserves, held in Lima, in March 2016,” Bokova said.
“Desertification is a global threat that requires global action—this must start with each of us, with our deeper engagement to protecting our planet for all to share,” she added.
For her part, the executive secretary of the UN Convention to Combat Desertification (UNCCD), Monique Barbut, said that land degradation neutrality should be a top policy goal for every nation that values freedom and choice.
“Conserving land and restoring that which is degraded back to health is not a benefit that only flows to the billions of people who eke out a living directly from the land,” Barbut said.
“It is a vote to safeguard our own freedoms of choice, and those of our children. It is also a moral standard against which we may well be judged by history,” she added.
