Mapping of ecosystem services
One key first step in understanding your environment can be mapping it using spatial data. While there are multiple data set categories that can be relevant for this type of assessment, common categories include:
Using spatial data
Mapping and classification of degradation (IUCN Red List of Ecosystems).vii
Expert opinion. Use of social science techniques such as interviews, surveys, and focus groups to determine the level of degradation.vi
Biophysical models. Development of Fuzzy Logic Modeling (FLM) for Land Productivity Assessment.v
Mapping degradation will be a key tool in your toolbox which can allow you to identify spatial patterns, overlaps, and gaps that are otherwise difficult to conceptualise. We recommend starting the mapping process with the degree of degradation and degree of restoration needed, followed by the services. Consider the feasibility of restoration during the mapping exercise.
Assessment of abandoned cropland. Based on a combination of the History Database of the Global Environment 3.0 (HYDE).iii Based on satellite data (E.g LANDSAT data for predicting soil taxonomic units and drainage classes).iv

Observations of degradation and degradation status in the field.
The most common approaches to mapping the level of degradation include:i

Remote sensing
There is a variety of datasets which might be useful for assessing the extent of degradation in your ecosystem. Explore examples which might be relevant to your project.
Types of datasets
REFERENCE
National, regional or local (e.g. municipal) level datasets can be important input data for mapping degradation or ecosystem services. This could include data from a variety of fields, such as ecological (e.g. forest type), biophysical (topography), social (human population density), and economic value (e.g. price of timber). Many of these data are gathered routinely by different international and national processes, and are often found in national statistics offices.
Regional/national statistics
REFERENCE
There are various ways to gather data in the field: collection by trained scientists, Indigenous Peoples and local community monitoring schemes, and focus group discussions. Surveys or questionnaires for inhabitants and hand-held computerized tools are also useful tools for data gathering. Field data can inform the mapping process, and can help to parameterize and validate models from remotely sensed data products.i
Biophysical and social data from the field
REFERENCE
This involves data collection from aircrafts or automated sensors on the ground, in water, or from space. Remote sensing can provide estimates of terrestrial and ocean primary production, allowing the production of crops, feed, wood, and biofuel, and changes in carbon stock to be measured. Declines in production levels can then be interpreted as an indicator of degradation. There is also potential for remote sensing to be used for monitoring inland and marine water quality and quantity.ii
Remote sensing
REFERENCE
Global datasets are readily available on the occurrence of fires, which can also be used as a proxy for degradation (screening out those due to natural fire regimes) (also available through the Global Fire Watch (GFW))iii. Many of these datasets can be put into Geographic Information System (GIS) programmes, many of which are freely available and at resolutions that may be useful for national-scale assessments of degradation/restoration priorities.
Global datasets
REFERENCE
The complexity of services, like climate or water regulation, often prevents data from being collected through the previous ways described. In these cases, empirical, statistical, or process-based models use other input variables to calculate ES values.iv

Multiple Tools to Support the Achievement of Land Degradation Neutrality (LDN)
These tools and resources were presented in the publication “Scientific Conceptual Framework for Land Degradation Neutrality: A Report of the Science-Policy Interface” as examples of sources of information that countries pursuing land degradation neutrality (LDN) could use.
The UN Biodiversity Lab provides access to the World Atlas on Desertification (WAP) Convergence of Evidence data in an easy form that can be accessed, visualized, and shared by non-GIS experts. This data layer offers some of the best global information on where degraded ecosystems are most likely to occur.
Co$ting Nature is a powerful tool in identifying priority service areas as it effectively ranks locations across the grid cells, across a user defined area, or across global values. It can also be used to assess the potential and use of ES in relation to conservation priority areas.
The Ecoregions 2017 mapping tool is a global assessment. It can help to scope out which ecoregions present at the national scale have lost most of their coverage globally.

Explore an example of how remote sensing data can support assessments of degradation.
Agriculture is a cornerstone of the Ethiopian economy. In Ethiopia, LANDSAT image reflectance bands were used to predict the degree of degradation through the assessment of the presence/absence of soil erosion, determination of soil pH, and classification of the organic carbon in the soil. Field data and soil samples collected from 38 sites, each 100 km2, were used to ground-truth and finetune the predictive models based on remote sensing.i The models developed in this study were able to explain most of the variability in Soil Organic Carbon (SOC) and pH, and the occurrence of soil erosion and root depth restrictions, when applied to an independent validation dataset.

Spatial data and participatory techniques are important in establishing reference ecosystems. The Society of Ecological Restoration (SER) defines a reference ecosystem as “a representation of a native ecosystem that is the target of ecological restoration (as distinct from a reference site).” A reference ecosystem usually represents a non-degraded version of the ecosystem complete with its flora, fauna, and other biota, abiotic elements, functions, processes, and successional states that might have existed on the restoration site had degradation not occurred, and adjusted to accommodate changed or predicted environmental conditions.i Reference models are needed to identify the dynamics of degradation. Degradation and restoration are relative terms: “degraded relative to what?” and “restored towards what?” A reference model is required to detect and assess both the magnitude of degradation and the progress of restoration.ii

A reference model is:
Based on measurable indicators of ecosystem composition, structure, function, and external exchanges.i
Based on multiple reference sites (sites that are similar to the designated area but that have no or limited degradation).
An estimate of the composition (species), structure (complexity and configuration), and function (processes and dynamics) of the ecosystem as if degradation did not occur.i
The reference ecosystem refers to the general type of ecosystem that is the target of restoration. However, after selecting the reference ecosystem, it is necessary to describe the ecosystem using measurable indicators that allow comparison with the restoration site. In order to do this, it is necessary to develop a reference model.i

You may need to adjust your reference model over time based on results of program monitoring.
You may need multiple references to reflect ecosystem dynamics or anticipated changes over time. Ecosystems with complex dynamics may need multiple pathways and multiple models describing different possible restoration outcomes. Such alternative states can result from changes in population densities, or in environmental drivers, or both.
If you’re working with a large site or one with varied topography, you are likely to include a mosaic of ecosystems.
You may need multiple reference models for your restoration program. Take note of the following considerations:i

Explore how the process of identifying a reference site for restoration was applied in Mexico.i
A workshop “Challenges and prospects to comply with international agreements on Ecological Restoration” aimed to understand whether the planning phase of restoration projects in Mexico was conducted according to international guidance. By assessing restoration projects over the past 37 years, it was determined that most of the projects were established at the following scales: landscape (63%), basin (65%), or ecosystem scale (45%). Overall, 88% of the restoration projects assessed in Mexico from 1979 - 2016 selected a reference site. Reference ecosystems were most commonly identified through remnant vegetation (59%), local knowledge (49%), or ecological studies (45%). Most restoration projects assessed (74%) included at least two criteria to compare degraded and non-degraded sites. The evaluation of abiotic conditions, such as temperature or humidity, was the most mentioned (28%). The presence of biological corridors, such as riparian vegetation, was the least mentioned (11%). Most restoration projects tended to select sites based on biotic, abiotic, physiographic, and/or social variables. Biotic variables were the most frequently used (43%), followed by abiotic variables (25%) and physiographic variables (12%). Social variables were the least used (8%). Learn more here.

The produced national opportunity map has been in constant demand by the Ministry of Lands and Natural Resources, the Forestry Commission, the National REDD Working Group, and other national and international stakeholders. The map and the economic analysis are currently being used for decision-making in the forest sector. The Government of Ghana has used the assessment results to prioritize the regions for their Forest Investment Programme.ii
The German Ministry of Environment, World Resources Institute (WRI), the Ghana Forestry Commission (FC), the Centre for Remote Sensing and Geographical Information System (CERSGIS) of the University of Ghana, among others, supported the mapping exercise. The workshop brought together representatives of government ministries, departments and agencies, as well as civil society and private sector actors working on forest management and rehabilitation of degraded forests.
The workshops provided relevant information for an economic analysis of various restoration options. This analysis led to the production of carbon abatement curves to rank the restoration interventions according to their net economic benefits per ton of CO2 sequestered. The workshop validated both the map of national forest landscape restoration opportunities, and the results of the economic analysis.
The initial forest cover maps for the 10 geographical regions in Ghana, produced by Management Support Centre (RMSC), formed the basis for a national multi-stakeholder workshop involving scientists, farmers, civil society groups, and others in a combined effort to engage local knowledge in estimating forest restoration potential in regional settings. The GIS map data and the information gained from the dialogues combined to lead the production of a national restoration opportunities map.
Ghana’s forest cover has shrunk considerably in recent years. To continue to meet Ghana’s forest resource needs, the government initiated a series of programmes designed to restore lost forests.

This publication explains the importance of assessing FLR potential.
Forest Landscape Restoration Potential and Impacts
UNCCD Knowledge Hub
The Hub outlines the steps needed to assess degraded land and ecosystems.
FLRM provides a number of resources to explore degradation of forests and landscapes, and assess the degree of degradation.
This report provides guidance on identifying and mapping current land degradation. It includes links to and descriptions of multiple land degradation assessment tools.
ROAM provides a flexible and affordable framework for countries to rapidly identify and analyse forest landscape restoration (FLR) potential, and locate specific areas of opportunity at a national or sub-national level.

Welcome to m2 l1
You should finish this lesson with a basic understanding of the following in your context: The current extent, type, degree, and location of degraded ecosystems in your context.Your reference ecosystem.
The key points to remember from this lesson are:
- The first step in an ecosystem restoration program is to analyze the current condition of an ecosystem in question, and the state of degradation.
Congratulations on completing Module 2 Lesson 1!
