“…After finishing this research, we want to highlight that a proper delineation of site-specific management zones should be considered in Iranian agricultural and forest land management strategies affected by potential or real degraded areas, which are tasks traditionally related to the soil geographers, biogeographers and geomorphologists [79,80]. However, now we state that there is a necessity for the development of prospective tools in management plans to correctly achieve land degradation neutrality coinciding with other authors [29,65], but always involving the whole scientific community, stakeholders and policymakers [81,82]. Land degradation is a big concern for the whole of humankind and neutrality.…”

“…However, there is a lack of information about the spatial distribution of soil degradation at the regional and sub-regional scales [24].Knowing the soil micronutrient content is important for elaborating correct and suitable land management plans [25,26], which are often not performed due to sampling costs and laboratory analysis [27]. One strategy used to reduce sampling costs and laboratory analyses is the delimitation of management areas, which could be an interesting tool to be included in plans to combat land degradation and achieve neutrality [28,29]. The delimitation of these sub-regions aims to achieve differentiated management focused mainly on correction and soil fertilization, considering the spatial variability of the nutrients [30].…”

The proper delineation of site-specific management zones is very important in the agricultural land management of potentially degraded areas. There is a necessity for the development of prospective tools in management plans to correctly understand the land degradation processes. In order to accomplish this, we present a pedo-geomorphological approach using soil texture, land elevation and flow vector aspects to distinguish different management zones and to discretize soil micronutrients. To achieve this goal, we conducted the study in the Neyshabur plain, Northeast Iran. For data collection, grid sampling (500 × 500 m) was used with 70 specific points. Soil samples were collected in triplicates from various sites as composite samples (0-30 cm) to analyse clay, Zn, Mn, Cu and Fe. Using the altitude information (obtained with GPS at each sampling point), flow vectors were also modelled for all selected points. Based on the values of altitude, flow vectors and clay, management zones were delimited using geographic information systems. The best data organization was obtained from the combination of clay + elevation + flow vector attributes, generating two different management zones. In this circumstance, the lowest fuzzy performance index (FPI) and modified partition entropy (MPE) values were generated. It can be observed that the management zone 1 (MZ1) is located in the areas with a lower elevation and higher content of clay. On the other hand, the MZ2 was characterized by areas with a higher elevation and lower clay content. This study concluded that the design of management zones, using pedo-geomorphological information could reduce the time and cost of sampling necessary to assess potentially degraded areas of land. reforestation or geotextiles are also successfully applied. However [10,11], the drastic decline in yield or wood production and the increase in soil degradation processes can also be attributed to the intensification of its cultivation or exploitation, as well as the imbalance in soil nutrient management and physical properties [12,13].It is unusual to assess soil degradation or delimitate land management zones via clay, Zn, Mn, Cu and Fe. However, recent research conducted by [14] in India demonstrated that micronutrient deficiency in intensively cultivated regions may be associated with a low organic availability and excessive reliance on chemical fertilizers. In Northern Greece, [15] assessed Fe, Mn, Zn and Cu bioavailability their correlation with foliar micronutrient concentrations in mature organic olive orchards, highlighting the key role of organic matter to sustain metal uptake by olive trees. However, it is not common to see clear examples showing how these data on micronutrients can be a basis for a land management planning tool to achieve land degradation neutrality. Usually, other robust indicators such as cation exchange capacity, base saturation, the content of soil organic matter, but in several cases, only a few data about soil chemical properties such as micronutrients are analysed...

“…Under these settings, recurrent floods will tend to aggravate these damages. If no prevention or recovery measures are taken, the flood-conflict issue may turn into a negative spiral ultimately leading to land degradation [47]. The return of a degraded land to a neutral condition is a priority given the economic and social costs of land degradation [48].…”

In many regions across the planet, flood events are now more frequent and intense because of climate change and improper land use, resulting in risks to the population. However, the procedures to accurately determine the areas at risk in regions influenced by inadequate land uses are still inefficient. In rural watersheds, inadequate uses occur when actual uses deviate from land capability, and are termed environmental land use conflicts. To overcome the difficulty to evaluate flood vulnerability under these settings, in this study a method was developed to delineate flood vulnerability areas in a land use conflict landscape: the Batatais municipality, located in the State of São Paulo, Brazil. The method and its implementation resorted to remote sensed data, geographic information systems and geo-processing. Satellite images and their processing provided data for environmental factors such as altitude, land use, slope, and soil class in the study area. The importance of each factor for flood vulnerability was evaluated through the analytical hierarchy process (AHP). According to the results, vast areas of medium to high flood vulnerability are located in agricultural lands affected by environmental land use conflicts. In these areas, amplified flood intensities, soil erosion, crop productivity loss and stream water deterioration are expected. The coverage of Batatais SP municipality by these vulnerable areas is so extensive (60%) that preventive and recovery measures were proposed in the context of a land consolidation–water management plan aiming flood control and soil and water conservation.

“…Specially, rural residents in China have a strong psychological dependence on agricultural land, which is the basis of maintaining interpersonal relationships. In rural-urban land conversion, fragmented habitats are increasing, and patches are generally small and isolated [44,45]. Soga et al [46]) described this progressive separation of humans from ecosystems as the "extinction of experience", especially for children, and viewed it as a major public health issue.…”

Rural-urban land conversion has led to the degradation of agricultural system ecological services, and therefore human ecological well-being. There is a need to transform the non-marketed value of ecosystem services provision into a monetary loss of ecological well-being in rural-urban land conversion, which could serve as a basis for ecological compensation. In this paper, a choice experiment method is adopted to investigate the willingness-to-pay (WTP) of rural and urban residents in six cities of three provinces selected from different regions in China. The results reveal that the attributes reflecting the ecological well-being of rural and urban residents are experiencing different degrees of decline. Two attributes, health and security, show the most obvious decline among all ecological well-being attributes for urban residents. In view of stakeholders, rural residents are facing a greater decline in ecological well-being than urban residents, which is mainly driven by their different linkages and interactions with the agro-ecosystem. In terms of regional comparisons, residents in the central region (Hubei Province) of China are subject to the sharpest decline in ecological well-being, followed by those living in the western region (Guizhou Province) and the eastern region (Guangdong Province). These differences are basically determined by their land resource conditions and socioeconomic circumstances. This paper argues that it is pressing to establish an ecological compensation mechanism to regulate rural-urban land conversion and maintain human ecological well-being.Sustainability 2020, 12, 3378 2 of 17 to provide various ES to human beings is gradually diminished, with the potential to further reduce human well-being [1,[9][10][11].Globally, it is one of the major challenges for policy-makers to keep a trade-off between economic development and agro-ecosystem protection. In most developing countries, especially in southern Africa and Asia, rapid urbanization and increasing human population are driving massive land transformation [12][13][14]. With the largest population and relatively scarce land resources, China has witnessed a significant growth in urbanization [15,16]. In recent years, ecological risks caused by rural-urban land conversion have attracted growing attention. The Central Government of the Communist Party of China (CPC) put forward the strategy of ecological civilization to reconcile the relationship between human and nature, taking "optimization of the spatial layout", "effective regulation of development scale", and "improvement of the ecology system" as main guidelines of future development mode. It is increasingly presenting not only as a response to eco-environment degradation in China but as a vision for our global future [17].Researchers have been sharing growing concerns about the impacts of rural-urban land conversion on agricultural ES and their impacts on human well-being. Several studies have adopted physical assessment methods [18][19][20] to uncover the relations between agri...
