“…To do this, Earth observation and monitoring by ground‐based surveys should combine to improve such assessments. The scientific research community is aware of the problem and several researchers are working to assess the potential LD following the UNCCD methodology application in various regions (Assennato et al, 2020; Mitri et al, 2019; Montanarella, 2020). The UNCCD SDG 15.3.1 methodology addressed the major process (primary productivity) and principles (loss of productivity over time) surrounding the task of assessing in a specific (short) timeframe at global scale.…”

“…Examples of country‐scale applications using the UNCCD approach, with the addition of supplementary Earth observation (EO) and soil monitoring data, include: Wunder and Bodle (2019), who designed a land use change‐based indicator for Germany, but could suffer from the decline in LP due to the decoupling strategies of the Common Agricultural Policy (e.g., reduction in agricultural intensity). A 20 m spatial resolution assessment was produced for Italy that included six additional variables: (i) loss of habitat quality; (ii) burnt areas: 2008–2018; (iii) fragmentation index; (iv) density of artificial LC; (v) density of buffer areas; and (vi) increase of small natural patches <1000 m 2 (Assennato et al, 2020).…”

“…The rising awareness of the intensification of global extreme weather events, led the United Nations (UN) and other organizations to develop a land degradation assessment and restoration framework that could be applied at a global-or country-scale level (Montfort et al, 2021). However, a few EU countries have set targets for reducing LD, which will in turn increase societal well-being and ensure the food security (Assennato et al, 2020). Dubovyk (2017) In 2013, the European Commission (Cherlet et al, 2013) reported an assessment and evaluation of LP dynamics, which aimed to assess land degradation for the implementation of the Rio 20 target of a 'land degradation neutral world'.…”

Land degradation is the persistent reduction in the capacity of the land to support human and other life on Earth (IPBES, 2018). This process jeopardizes the provision of ecosystem services. The Sustainable Development Goal (SDG) 15, 'Life on Land', includes efforts to sustainably manage and recover natural ecosystems and restore degraded land and soil. Under the umbrella of SDG 15, the United Nations Convention to Combat Desertification (UNCCD) has defined an indicator framework to monitor progress toward 'land degradation neutrality'. We evaluated the performance of SDG 15.3.1, focusing on "...proportion of land that is degraded over the total land area" for the European Union (EU) using the TRENDS.EARTH software. We assessed the impact of alternative datasets at different spatial resolutions and policy-relevant data sources for land cover (CORINE) and soil organic carbon (SOC) stock (LUCAS). Our hypothesis was that higher spatial resolution sub-indicators would better identify the total share of degraded land and provide a clearer picture of the extent of degraded land for the target period. Land productivity trajectories were adjusted using the Water Use Efficiency index that revealed the high share of improving land reported by the NDVI trends. Therefore, it is advisable to use always a climate correction to assess land productivity trends. Replacing default datasets with alternative sub-indicators allowed the detection of 25-40% more degraded areas.Additionally, the integration with a combined proxy of land degradation (soil erosion >10 Mg ha À1 yr À1 , and SOC concentration <1%) identified an additional 50% land degradation and revealed that a large extent of the EU needs restoration measures.

“…In Italy, where land degradation processes due to land consumption are increasing, especially in agricultural and peri-urban areas [43], the Italian Institute for Environmental Protection and Research (ISPRA) is in charge of a monitoring program at the national level regarding: (i) land consumption mapping, based on a Sentinel satellite images analysis that is integrated with the photointerpretation of national orthophotos; (ii) land cover mapping, based on the integration of the Copernicus Land Monitoring Services (CLMS) datasets (Corine Land Cover, High Resolution Layers, Urban Atlas, Riparian Zones, and Natura 2000) and the national land consumption map; (iii) estimate of land degradation and ES changes (biophysical and economic) caused by annual land consumption. This study is the first work that is focused on Italy and that, in trying to collect and harmonize existing data, analyzes nationwide soil-based ES loss with a detailed spatial resolution.…”

Urbanization and related land consumption are one of the main causes of ecosystem services loss. This is especially the case for soil-related services affecting ecosystem functions and limiting accessibility to natural resources. Satellite remote sensing and environmental databases enable in-depth analysis of urban expansion and land changes, which can be used to monitor trends in the provision of ecosystem services. This work aims to describe a multilayered approach to the assessment of biophysical loss of ecosystem services flows in Italy caused by an increase in land consumption in the period 2012–2020. The results show higher losses in wood production, carbon storage, hydrological regime regulation, and pollination in the northern regions of Italy, as well as in some southern regions, such as Campania and Apulia. Habitat quality loss is widespread throughout Italy, whereas crop production loss varies on the basis of the locations in which it occurs and the crop types involved. Loss of arable land and fodder production mainly occurs in northern regions, whereas southern regions have experienced a drop in permanent crop production. This study highlights the importance of using integrated data and methodologies for well-founded approaches, with a view to gaining a thorough understanding of ecosystem services-related processes and the changes connected therewith.

“…Zenebe et al (2018) assessed the extent of LU changes and NDVI and their links to land degradation in Ethiopia. Assennato et al(2020) estimated land degradation in Italy to be about 36% based on three sub-indicators of SDGs15.3.1 (land use/land cover, land productivity and soil organic carbon trends) and related indicators with significant local impact. Mancino et al (2022) used the median of non-parametric Theil-Sen estimation to analyze the multi-time NDVI trend, and used Mann-Kendall test to evaluate the trend significance characteristic area.…”

Land degradation is a global environmental issue receiving much attention currently. According to the definition and interpretation of land degradation by relevant United Nations organizations, land use degradation was qualitatively analyzed based on the two periods of land use data in 2001 and 2020, land use transfer matrix and change flow description table in 2001 and 2020. At the same time, here we employed the Vegetation Continuous Fields MODIS data over the span of 21years (2000–2020) to quantitatively estimate vegetation degradation by using the Theil-Sen Median trend and Mann-Kendall non-parametric test. And the land degradation situation in Pakistan was comprehensively evaluated by combining the results of qualitative and quantitative analysis. Major findings of this study indicate: (1) unused land (61.91%), cropland (20.7%) and grassland (15.88%) are the major types of land use in Pakistan. Unused land area decreased during whole period, while other land areas increased, the grassland area changed the most, the cropland area increased the most, and the conversion between grassland and unused land was the most significant. (2) The average vegetation coverage in Pakistan is low, but showed a significant upward trend during whole study period, with a growth rate of 0.0786/a. The vegetation degradation area accounts for only 1.32% and the vegetation improvement area accounts for 28.79%. (3) 2.15% of the land was degraded, of which land use degradation accounts for 1.9% and vegetation degradation only accounts for 0.25%. Land use degradation is mainly due to vegetation loss (53.78%) and withdrawal of agriculture (40.07%). 22.41% of the land has been improved, of which land use improvement accounts for 5.75% and vegetation improvement accounts for 16.66%; The improvement of land use is mainly due to agricultural expansion (48.9%) and vegetation establishment (48.81%). The degradation and improvement of land use in Pakistan are mainly affected by grassland, followed by cropland. The research shows that there are serious phenomena of cropland abandonment, vegetation loss and over agricultural expansion in Pakistan, but thanks to Pakistan's efforts in forest restoration and ecological protection in recent years, the overall vegetation coverage has been significantly improved. At the same time, we found that the regional distribution of land degradation and improvement has obvious spatial similarity, which is mostly distributed in the transition area from northern mountainous area to central plain, central and eastern plain and the Indus River Basin. The distribution of cropland and built-up land is similar in space. Meanwhile, we found that land degradation in Pakistan is significantly affected by human activities. The government and people should devote more energy to optimizing the use of cropland land resources, reasonably reclaiming wasteland for cropland land, and protecting forests and vegetation. This paper provides a new idea for land degradation assessment, and the assessment results can optimize the use of land resources to improve the current situation of land degradation and serve the sustainable development of land resources in Pakistan.
