It is proved that increasing the level of anthropogenic loading on agroecosystem leads to negative destructive changes in the state of agricultural land, which poses a potential threat to the level of agroecological and food safety. Under of the existing organizational and economic conditions of commodity production in the crop production sector, there are no trends towards positive changes in the expansion of the complex of implementation of land conservation measures and the prudent attitude towards the use of agricultural land. Instead, the increase in profits and yields, the expansion of arable land in the narrowing of the agricultural land provoke a decrease in the level of agroecological safety, the spread of erosion and degradation processes, the decrease of humus stocks and the level of fertility However, despite the increase in the economic efficiency of the crop sub-sector of agriculture, the scope and organization of the implementation of measures to restore and preserve agroresource potential require radical changes on scientifically grounded positions.

Using Data

Smallholder agriculture is a major source of income and food for developing nations. With more frequent drought and increasing scarcity of arable land, more accurate land-use planning tools are needed to allocate land resources to support regional agricultural activity. To address this need, we created Land Capability Classification (LCC) system maps using data from two digital soil maps, which were compared with measurements from 1305 field sites in the Dosso region of Niger. Based on these, we developed 250 m gridded maps of LCC values across the region. Across the region, land is severely limited for agricultural use because of low available water-holding capacity (AWC) that limits dry season agricultural potential, especially without irrigation, and requires more frequent irrigation where supplemental water is available. If the AWC limitation is removed in the LCC algorithm (i.e., simulating the use of sufficient irrigation or a much higher and more evenly distributed rainfall), the dominant limitations become less severe and more spatially varied. Finally, we used additional soil fertility data from the field samples to illustrate the value of collecting contemporary data for dynamic soil properties that are critical for crop production, including soil organic carbon, phosphorus and nitrogen.

Purpose. The main objective of this paper is (і) to determinate the economic loss due to crop productivity loss caused by soil erosion in Ukraine, and (іі) to present the results of the econometric modeling of soil erosion impact on the efficiency crop production at the regional and district level. Methodology / approach. This study uses the following methods: expert assessments and monographic (for the assessment of economic losses due to crop productivity loss from spreading soil erosion); graphical (for building three-dimensional graphs); econometric modeling (to develop a mathematical model of the dependence of the gross crop production and income from sales per 100 hectares from the share of eroded arable land in its total area and production costs in crop industry per 100 hectares); abstract-and-logical (for generalization of the research results). To solve the assigned tasks, linear and quadratic econometric models (production functions) were developed using a dataset (і) from 168 observations (on the example of Ukrainian regions for 2010–2016) and (ii) from 189 observations (on the example of districts of Kharkiv region for 2010–2016). This study was conducted in order to test the hypothesis that the increase in the area of eroded arable land has a negative effect on the gross output of crop production. Results. Our expert assessment of economic losses due to crop productivity loss from spread of soil erosion on agricultural land in Ukraine is 224 mln USD. The obtained results confirm the hypothesis about the negative relationship between gross crop output and the level of land erosion. The obtained data confirm that an increase in the area of eroded arable land by 1 % leads to a decrease in the gross output of crop production by 0.20 % per 100 hectares of agricultural land in total, and in the third group of the studied subjects (the share of eroded arable land in their total area is more than 50 %) – by 0.61 %, respectively. Originality / scientific novelty. For the first time, linear and nonlinear (quadratic) econometric models were developed, which made it possible to carry out quantitative assessment of the impact of the soil erosion and the financial support (production costs in crop industry) per hectare on the formation of the financial results (gross crop output and income) of business entities in Ukrainian agriculture. The provision on the economics of soil erosion was further developed in terms of expert assessment of losses from this type of degradation and confirmation of the effect of the economic law of diminishing returns, which should be taken into account when developing measures for sustainable land management. Practical value / implications. The main results of the study can be used for the development, substantiation and implementation of soil protection measures for the sustainable use of agricultural land and/or to informed decision-making at different levels of management concerning restoration of eroded land.

Agriculture terraces constitute a significant element of the Mediterranean landscape, enabling crop production on steep slopes while protecting land from desertification. Despite their ecological and historical value, terrace cultivation is threatened by climate change leading to abandonment and further marginalization of arable land imposing serious environmental and community hazards. Re-cultivation of terraced landscapes could be an alternative strategy to mitigate the climate change impacts in areas of high vulnerability encouraging a sustainable agroecosystem to ensure food security, rural development and restrain land desertification. The article presents the case study of abandoned terrace re-cultivation in the Aegean Island of Andros, using a climate smart agriculture system, which involves the establishment of an extensive meteorological network to monitor the local climate and hydrometeorological forecasting. Along with terrace site mapping and soil profiling the perfomance of cereal and legume crops was assessed in a low-input agriculture system. The implementation of a land stewardship (LS) plan was indispensable to overcome mainly land fragmentation issues and to transfer know-how. It was found that climate data are key drivers for crop cultivation and production in the island rainfed farming system. The study revealed that terrace soil quality could be improved through cultivation to support food safety and stall land degradation. In line with global studies this research suggest that cultivation of marginal terraced land is timely through a climate smart agriculture system as a holistic approach to improve land quality and serve as means to combat climate change impacts. The study also discusses land management and policy approaches to address the issue of agricultural land abandonment and the benefits gained through cultivation to the local community, economy and environment protection and sustainability.

It is estimated that the global population will reach approximately 10 billion people by 2050 and 66% of the world population will live in urban areas. This growth in cities creates demand for fresh products to maintain a healthy population, a product that often exposed to a long journey to reach the consumer, not only losing quality and nutritive value in the process, but also requiring a significant cost of fossil fuel for transportation and storage. However, the world’s agricultural land among being limited, is also facing major problems such as pollution, salinization and drought that do not favor crop production. The need for food security has paved the way for landless agriculture, becoming more popular in the urban area and becoming a part of urban farming. This article aims to examine hydroponic technologies to help expand the knowledge of their application in terms of science, origin, dynamics and farming systems. Among the benefits of soilless cultures; reservation of cultivated land for main crops; saving at least 90% of irrigation water; use of almost constant amount of recycled water; successfully growing almost every vegetable crops and having highest productivity compared to conventional agriculture. Therefore, it is an indispensable solution in areas where arable land is not available or in saline-prone areas, in short, wherever there is competition for land and water. The purpose of this study is an overview of soilless farming systems, explaining the most widely used hydroponic system, the importance of water quality, nutrient content, grown crops and ultimately cost benefit in terms of economics.

The paper reveals the experimental results of long-term agroecological monitoring of agricultural land, conducted by Tomsk state agrochemical service, and experiments on designing the measures to improve efficiency of acidic arable land. In Tomsk region, 83% of arable land is acidic and the degree of acidity increases annually. Every 10 years weighted average pH is reduced on 0.1-0.2 units; the area of acidic soils increases. There is an urgent need for liming these soils in order to improve efficiency of agricultural production in Tomsk region. According to the calculations, the region requires 3,248 million tons of chalky flour. The region has its own large deposits of limestone, for example Kamenskoe (61 million tons), located 50 km from Tomsk, where it is possible to produce valuable meliorant, increasing efficiency of agricultural production. The authors make case, that for successful development of agricultural production in Tomsk region, it is necessary to design and implement long-term target program “Chalking of acid soils in Tomsk region”, which assumes compensation for agricultural producers for the part of the cost of liming; design and technical support of works; local production of limestone meliorants. Implementation of the acidic soil liming program will increase annual crop production in Tomsk region on 54.9 - 129.2 thousand tons of grain units, therefore it will increase annual income on 494.1 - 1162.8 million rubles (in 2017 prices), as well as ensure further increase in agricultural land fertility with high fertilizer efficiency, product quality and profitability.

Abstract Background: Appropriate decision-making on crop production will reduce various risk factors associated with unsustainable land management. The limited available arable land be taken for granted which may turn from ‘best’ to ‘worst’ irrespective of the kind of land use and management practice without understanding its special requirements and potential use. GIS has contributed to the speed and efficiency of the overall planning process in agricultural land use suitability, since it enables quick and efficient access to large amounts of information, exhibiting relationships, patterns, and trends that are useful in monitoring land use potential and suitability evaluation. As crop’s environmental requirements vary from variety to variety, it is recommended to undertake variety specific analysis and mapping for better understand the extent of scaling-up the specific crop technologyResults: GIS-based land suitability map for chickpea was generated for each variety under consideration mapped showing their percentage area coverage of suitability for each regional states in Ethiopia. Based on, the suitability analysis desi chickpea varieties Mastewal, Naatolii, Teketay and Arerti, Habru, Kasech, and Yelbey kabuli chickpea varieties classified as highly suitable that cover 0.67, 0.71, 1.4, 2.3, 1.3, 2.4 and 1.2 million ha of the country respectively. While moderately suitable areas for the same varieties cover 25.2, 11.3, 25.9, 26.4, 26.6, 9.6, 17.1 million ha.Conclusion: The suitability analysis results show that the currently available improved varieties of chickpea can be targeted for scaling out in the identified land suitability classes in Ethiopia with some caution. Amhara, Oromia, SNNP and Tigray remain the major regions with suitable areas for production of available varieties of chickpea compared to Afar, Benishangul Gumuz, Gambella, and Somali regions. However, the highly suitable areas are limited compared to moderately suitable areas, which are higher across the regions.

Abstract In the last decade of the twentieth century, there have been significant negative transformations of arable land in the main agricultural regions of Russia. Traditional and zonal farming systems were disrupted, extensive agricultural technologies began to prevail with low doses of mineral fertilizers, a sharp reduction in the number of soil treatments and the use of organic fertilizers and ameliorants, disruption of crop rotation, and burning of stubble. Under these conditions, degradation processes have developed extremely strongly: erosion and plowing, dehumification and acidification, alkalization, and salinization. Many lands turned out to be abandoned, the weediness of crops increased sharply. With a decrease in the real (effective) land fertility and the level of technological culture of agriculture, the profitability of crop production fell sharply. The volume of soil protection and erosion control measures has sharply decreased. Traditional recommendations on soil-protective crop rotations and agrotechnics in the new economic conditions turned out to be practically inaccessible for most farms and cooperative farms, the necessary condition for the survival of which is a quick return on financial investments. The development of agricultural production in the current environmental and economic conditions (the vital need to increase the profitability of production, on the one hand, and a serious aggravation of the agroecological situation and, as a consequence, the increase in environmental and economic risks of production, on the other) requires a transition to adaptive landscape farming systems, which are the next stage of landscape-ecological detailing and economic and economic adaptation of previously developed zonal farming systems.
