Operationalizing an integrative socio-ecological framework in support of
global monitoring of land degradation
Abstract
Despite sustained global efforts to avoid, reduce, and reverse land
degradation, estimates of land degradation nationally and regionally
vary considerably. Land degradation reduces agricultural productivity,
impacts the provision of vital ecosystem services, and
disproportionately affects vulnerable populations. The 2030 Agenda for
Sustainable Development, through Sustainable Development Goal (SDG)
15.3, sets out to achieve land degradation neutrality (LDN) by improving
the livelihoods of those most affected and building resilience in areas
affected by or at risk from degradation. The United Nations Convention
to Combat Desertification (UNCCD) leads the charge in creating a
spatially-explicit framework for monitoring and reporting on LDN goals
that countries can integrate into their land planning policies. However,
it remains difficult to operationalize the integration of biophysical
indicators of land degradation with climatic and socio-economic
indicators to assess the impact of land degradation on vulnerable
populations. We present an integrative framework that demonstrates how
freely available global geospatial datasets can be leveraged through an
open-source platform (Trends.Earth) to simplify and operationalize
monitoring and reporting on progress towards achieving LDN. Then, we
summarize a suite of datasets and approaches that can be used to
understand and quantify the socio-ecological interactions between
drought, land degradation and population exposed to desertification,
land degradation and drought (DLDD). We discuss how improvements in
Earth Observation (EO) datasets and algorithms will allow UNCCD
land-based progress sub-indicators (changes in primary productivity,
land cover, soil organic carbon, drought, and population exposure) to be
computed at enhanced spatial resolutions.
