UNITED NATIONS, Nov 13 2018 (IPS) - A new landmark initiative aims to make
quality data and tools available to the international community in order to
combat an “existential crisis”: land degradation.

The Land Degradation Neutrality Initiative (LDN), launched by United
Nations-backed partnership the Group of Earth Observations (GEO), aims to
put data directly into the hands of local and national decision makers to
help stop and reverse environmental degradation.

“Land degradation is an existential crisis. Until now, monitoring it in
real time felt like an insurmountable challenge. No longer,” said Executive
Secretary of the United Nations Convention to Combat Desertification (UNCCD)
<https://www.google.co.za/search?q=united+nations+convention+to+combat+desertification+%28unccd%29&oq=United+Nations+Convention+to+Combat+Desertification+%28UNCCD%29&aqs=chrome.0.0l2.346j0j7&sourceid=chrome&ie=UTF-8>
upon welcoming the new initiative.

“With Earth observation datasets and the practical tools to use them
readily available, decision-makers and land users will have immediate and
actionable information to scale up sustainable land management and
planning. It is a first step to boosting our resilience,” she added.

According to the UNCCD, land quality is getting worse as over 75 percent of
the world’s land surface is significantly and negatively impacted by human
activity across 169 countries.

The consequences of the growing problem includes more and severe droughts,
high loss of wildlife, internal displacement, and forced migration.

In fact, without urgent climate action, Sub-Saharan Africa, South Asia, and
Latin America could see more than 140 million people move within their own
countries by 2050, further increasing competition for shrinking space.

The lack of action on one of the world’s biggest environmental problems is
largely due to the lack of accurate data and tools to monitor it.

“At national and local levels, monitoring has been essential to government
responses to land degradation,” UNCCD’s Policy Officer Sasha Alexander and
lead scientist Barron Joseph Orr told IPS.

They also noted the lack of uniform indicators in order to monitor and
measure land degradation.

In 2009, a global survey revealed that nearly 1,500 unique indicators were
being used by countries to monitor the challenge.

“In order to have a harmonised understanding of this major environmental
challenge, it has become clear that a minimum set of essential variables,
combined with the flexibility for countries to add additional indicators
deemed nationally or locally relevant, would be necessary,” Orr said.

The GEO LDN initiative, unveiled in Kyoto last week, hopes to bring
together Earth Observation (EO) data providers and governments in order to
develop quality standards, analytical tools, and capacity-building to
strengthen land degradation monitoring and reporting.

The importance of such data is also recognised in the globally-adopted
Sustainable Development Goals (SDGs) which includes a target to combat
desertification and land degradation and an indicator to assess the
proportion of land that is degraded over total land area.

Of course, data alone will not be enough to combat degradation.

But with the right data, governments will be able to prioritise
interventions as well as plan and manage land better.

“Using an agile development approach…governments with limited capacity are
now able to do far more with monitoring data than in the past, not only
reporting at the global level, but using what is being learned from these
data sets to make the course corrections necessary to help ensure the right
mix of interventions to avoid, reduce and reverse land degradation,”
Alexander told IPS.

She pointed to the case of Brazil which successfully implemented a project
to reverse degradation in the drylands region of northeastern Brazil.

After using data to identify priority areas, the Recovery Units of Degraded
Areas and Reduction of Climate Vulnerabilities (URAD) initiative was
established to finance actions including the provision of techniques and
trainings to municipal governments.

The initiative recognised that environmental actions alone will not be
sufficient as economic and social aspects must be taken into account in
order to have lasting change.

While local communities have long been suspicious of government projects,
the effective participation of populations and the project’s promotion of
sustainable value chains and income generation help inspire “noticeable
attitude and behaviour changes.”

Alexander noted that Brazil provides an example of how LDN can be achieved,
and why it is crucial to link global and national monitoring with more
site-specific monitoring at the project level.

The GEO LDN initiative has already been garnering interest worldwide from
developing and developed countries alike.

Following the launch, Germany committed 100,000 Euros towards the cause,
and more can be expected to come.

The GEO LDN initiative is a result of UNCCD’s call made at the Conference
of the Parties (COP13) to bring data providers and users together and
support global efforts to halt, reduce, and reverse land degradation.
