Clear Understanding

Land degradation is one of the most pressing problems ensuring sustainable use of land. In order to provide a clear understanding of land degradation and its risks, as well as to implement unified measures for prevention of land degradation in Latvia, the Land Management Law came into force in 2015. It individually defines the concepts of land and soil degradation, thus separating them from each other, as well as clarifying the term “degraded territory”. However, despite these solutions in the regulatory framework of the land degradation, till now criteria for identifying land degradation have not been developed and approved, therefore their determination is very subjective and not comparable between municipalities and at the state level. The aim of the article is to develop and approbation degradation criteria for assessing land degradation in particular territory. In the article, based on the author's previous studies on the classification of land degradation, characterised one type of land degradation - the abandoned agricultural and forestry activity territory, as well as proposed subdivision of criteria classification into three levels – low, medium and high. As result of the study, it was concluded that the classification of degraded territories into three degradation levels is justified for the purpose of more objective identification and evaluation of land degradation.

Sustainable Land Management

Sustainable land management has emerged as an issue of major global concern. In many countries particularly in Ethiopia, the concern of suitable land management is because of the increasing population pressure on limited land resources, demanding for increased food production, the degradation of land and water resources accelerating rapidly. If the lands well suited for agriculture, it will follows further increases in production to meet the food demands of increasing populations, must come about by the more intensive use of existing agricultural lands. Climate & soil conditions, land use type and management, determine the production limit.To contest cited venomous effects of intensification, regard to environmental effects requires the development and implementation of technologies and policies, which will result in sustainable land management (Gisla-dottir and Stocking, 2005; Campbell and Hagmann, 2003). The major factors reason for low productivity include dependence on traditional farming techniques, soil degradation caused by overgrazing and deforestation, poor corresponding services such as extension, credit, marketing, infrastructure, and climatic factors such as drought and flood (Deressa, Hassan, & Ringler, 2011). In addition to the low soil fertility, soil degradation in Ethiopia; reduces soil productivity which results to food insecurity, economic losses and aggravates the recurrent droughts (Shiferaw & Holden, 1999; Mitiku et al., 2006). It has also increases vulnerability of people to the adverse effects of climate variability and change, by reducing soil organic carbon level and water holding capacity, which in turn decreases agricultural productivity and local resource assets (TerrAfrica, 2009; Nyssen et. al., 2003a; Hurni, 2000; Mitiku Haile,2006 & Daniel et al., 2015). Climate change causes wide-ranging effects on the environment, socioeconomic and associated sectors: water resources, agriculture and food security, human health, terrestrial ecosystems, and biodiversity (Belay Zerga & Getaneh Gebeyehu, 2016). Ethiopia is extremely vulnerable to climate related disasters including drought, heavy rains, floods, frost and heat waves which leads to a negative impacts on agriculture, food security, rural livelihoods, and economic development (NMA 2007). Planning of changes in land use requires a inclusive knowledge of the natural resources; a trustworthy estimate of what they are capable of producing, so that reliable predictions and recommendations can be made. Production potential, the conservation of soil and water resources for use by future generations requires consideration in planning land development. For these reasons sustainable land management is now getting considerable attention from development experts, policy makers and researchers. In long-term period, any utilization over its capability of the land will cause degradation and yield reduction. Therefore, to know the land production capacity and to allocate the land to the satisfactory and to the most profitable should be cared.

<p>Hyperspectral data acquired for different seasons provide the means to derive relevant plant biophysical properties during the growing season over agricultural areas, as well as determine soil properties, when the soils are exposed, e.g. during fallow or after harvesting. This combined information can give a detailed insight on the effect of soil degradation on vegetation growth and finally crop yield. In the Mediterranean region, land use practices for crop cultivation have a long history exploiting soils as a natural resource. The soils are an essential factor contributing to agricultural production of rainfed crops such as cereals, olive groves and vineyards. Inadequate land management is endangering soil quality and productivity, and in turn crop quality and productivity are affected. Therefore, the main objective of this work is to map crop stress related to soil degradation and land management practices within a Mediterranean environment focusing on hyperspectral data within the visible, near-infrared, and short-wave infrared as well as thermal infrared (0.4-12 µm) and test the transferability of the methods used to future hyperspectral space-borne sensors such as PRISMA, EnMAP, SHALOM, CHIME and SBG.</p><p>In this framework, CASI and AHS hyperspectral imagery have been obtained during the growing season within the Camarena agricultural area located in central Spain. The area is characterized by a Mediterranean climate, a gently undulating relief, evolved soils and traditional rainfed agriculture area. In this environment a combination of tillage erosion as a result of plowing practices, as well as water erosion, has led to the exposure of different soil horizons at the surface with contrasting soil properties. These surface properties have been previously characterized as erosion stages of the same cultivated area in a fallow state. Simultaneous to the airborne acquisitions, intensive field campaigns took place for the characterization of soil and crop variability. This included field spectroradiometry measurements of the different surface covers and vegetation parameters such as Leaf Area Index (LAI), leaf chlorophyll content, plant biomass and grain yield in locations with variable soil erosion and deposition stages from low to very high eroded soils. First results based on random forest modeling between the soil erosion stage mapping and the AHS/CASI remote sensing imagery of the growing season indicate a strong link between the soil conditions and the spectral properties of the crops. Furthermore, biophysical parameters derived from the imagery in the green season such as Leaf Area Index and Leaf Water Content correlated also well with the soil erosion stages. For selected test sites it could be shown that low crop yields are associated with 1) highly eroded areas, where exposure of the calcite rich bedrock can cause deficiency in nutrient uptake and 2) very sandy accumulation areas that are depleted in nutrients and have low potential for water retention. Whereas highest crop yields are associated with clay and iron rich, moderately to low eroded soils. This study integrates optical VNIR-SWIR-TIR spectral domain and present preliminary results that emphasize the strong influence of soil quality on crop stress and production.</p>

This study aimed at determining the effect of land use on soil degradation, discovering the indicator as a determinant factor of soil degradation, and providing recommendations for land management to improve soil productivity. This study was conducted in agricultural lands in Giriwoyo, Wonogiri, Indonesia, and the observation indicator adopted by the Indonesian Government Regulation concerning Soil Degradation Control for Biomass Production. The methodology used was survey research with purposive sampling points in 12 land mapping units, and each unit was represented three times. The result showed that the study area was slightly and moderately degraded. Land use significantly affected soil degradation, and the paddy field has the highest degradation in the study area. Soil characteristics as degradation factors in the study area were soil texture, bulk density, and total porosity. Strategy for land management can be made by limiting the use of chemical fertilizers, and changing the use of chemical fertilizers into compost, to increase soil organic content, and accelerate the availability of nutrients.

Abstract Soil is the most important component in agriculture. Soil degradation is caused by improper soil management, unpatterned planting, and homogeneous rainfall. Mapping of potential soil degradation was a process of identifying initial conditions to determine areas that have the potential in soil physical, chemical, and biological degradation. The purpose of this study was to create a map of Soil Degradation Potency (SDP). The research was conducted in Nguntoronadi district, Wonogiri. The mapping used a guided-qualification method and was assisted by ArcGIS application for overlaying the maps according to standard procedures, and the resulting value of soil degradation potency. The results showed the soil degradation potency was slightly in 454 hectares, moderate in 5,186 hectares, and high in 192 hectares. The research area was dominated by moderate to high degradation. Land management requires more attention according to soil conservation and sustainability. Further research is needed to determine the actual level of soil degradation to obtain recommendations for sustainable land management.
