The consequences of improper land management are long-term, inadequate for agricultural production, and reflected through the loss of land, reduced yields, soil erosion, etc. In order to determine the optimal role or suitability of the land for apple cultivation within the Bužim municipality, a survey was conducted according to the FAO method of AEZ (FAO, 1976), and based on the obtained results, an assessment of the suitability of the land for apple cultivation was carried out. It was found that a significant land portion of the total of 13,026.27 ha agricultural land within the Municipality of Bužim is suitable for fruit production marked from S1 to N suitability class. Thus, the areas with the best graded class S1 cover only 1.23% or 159.52 ha, the S2 class occupies 5.51% (717.24 ha), the S3 class occupies 2.29% (298.24 ha). However, the largest areas are marked as the unfavourable N-class with 36.68% (4,772.60 ha). It is evident that pre-existing conditions for apple production within the municipality do exist. With the implementation of the necessary measures of soil/ land regulation, education of agricultural producers, and mindfulness of constraint factors hindering intensive production such as terrain slope, depth, rockiness and soil response, progress in production can be made.

The Impact

Agricultural land abandonment is a process observed in most European countries. In Poland and other countries of Central and Eastern Europe, it was initiated with the political transformation of the 1990s. Currently, in Poland, it concerns over 2 million ha of arable land. Such a large acreage constitutes a resource of land that can be directly restored to agricultural production or perform environmental functions. A new concept for management of fallow/abandoned areas is to start producing biomass for the bioeconomy purposes. Production of perennial crops, especially on poorer soils, requires an appropriate assessment of soil conditions. Therefore, it has become crucial to answer the question: What is the real impact of the fallowing process on soil, and is it possible to return it to production at all? For this purpose, on the selected fallowed land that met the marginality criteria defined under the project, physicochemical tests of soil properties were carried out, and subsequently, the results were compared with those of the neighboring agricultural land and with the soil valuation of the fallow land, which was conducted during its past agricultural use. The work was mainly aimed at analyzing the impact of long-term fallowing on soil pH, carbon sequestration and nutrient content, e.g., phosphorus and potassium. The result of the work is a positive assessment of the possibility of restoring fallowed land for agricultural production, including the production of biomass for non-agricultural purposes. Among the studied types of fallow plots, the fields where goldenrod (Solidago L.—invasive species) appeared were indicated as the areas most affected by soil degradation.

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 The essential way of realization of the Common Agricultural Policy in EU is through the financial support. One of the basic ways of financial support are subsidies. The huge segment affecting the agricultural sector is necessary to define, describe or classify so that we can might it to best analyse and understand. The aim of this paper is to evaluate the development of agricultural subsidies granted per hectare of agricultural land in Slovakia in terms of territory. The difference between the individual regions was evaluated using one-way analysis of variance. This analysis confirmed the existence of statistically significant differences between the amounts of subsidies per hectare of agricultural land provided to agricultural entities in terms of individual regions. This fact shows that firms in regions with worse natural and climatic conditions achieved a higher amount of financial support than companies in regions where agricultural production has better conditions and a long-term tradition.

The paper presents theoretical approaches to assessing the effectiveness of introducing fallow lands into agricultural production, justifying the feasibility the measure implementation. The methodology of ecological and economic case of the introduction of long-term unused lands into agricultural circulation or their transfer to other categories has been developed. A distinctive feature of the proposed solutions is the search for a balance between natural and climatic potential of the territory limitations and the possibilities of agricultural production resource potential, as well as reducing the risk of not achieving the economic efficiency of investments in restoring the economic value of long-term unused lands. The research methodology is based on the generalization and comparative analysis of solutions in the field of management, mathematical statistics, simulation and analytical modeling of a sustainable agroecosystems production process. An algorithm for the land user needs assessment in the growth of agricultural production is presented, the absence of which is a reason to refuse additional areas. The procedures and operations for analyzing the ecological and economic, socio and economic efficiency of the fallow lands using have been established on the basis of which an integral assessment of the feasibility of putting them into operation is carried out. Recommendations are given for calculating the overall economic effect and risk at the final stage of the ecological and economic substantiation of land introduction into agricultural circulation. The fallow agricultural land in agricultural production using will help to increase the efficiency of the Russian government implementation decisions on the development of the domestic agro-industrial complex.

The youth constitute an important human capital for the socio-economic growth and development of Ghana. As an agrarian economy, land remains a key resource in national economic development. Consequently, youth access to agricultural land is crucial in harnessing their potential for increased agricultural production. This study examines youth access to agricultural land dimensions under the customary system in Ghana. Using Techiman area as a case study, the study employed multiple sampling techniques to select the study communities and the respondents. In all, 455 youth and 23 elder respondents were covered. The results revealed that the youth have limited access to land for agricultural purpose on permanent basis. Land access mechanisms which convey temporary and limited rights such as licence and rentals were more popular among the youth respondents. This undermines their ability to make long-term investments and participate in cash crop cultivation. The study recommends a targeted youth agricultural land policy by government that will leverage the potential of the youth for increased agricultural production in the country.

Soil salinity is a serious threat to coastal agriculture and has resulted in a significant reduction in agricultural output in many regions. Jaffna Peninsula, a semi-arid region located in the northern-most part of Sri Lanka, is also a victim of the adverse effects of coastal salinity. This study investigated long-term soil salinity changes and their link with agricultural land use changes, especially paddy land. Two Landsat images from 1988 and 2019 were used to map soil salinity distribution and changes. Another set of images was analyzed at four temporal periods to map abandoned paddy lands. A comparison of changes in soil salinity with abandoned paddy lands showed that abandoned paddy lands had significantly higher salinity than active paddy lands, confirming that increasing salts owing to the high levels of sea water intrusion in the soils, as well as higher water salinity in wells used for irrigation, could be the major drivers of degradation of paddy lands. The results also showed that there was a dramatic increase in soil salinity (1.4-fold) in the coastal lowlands of Jaffna Peninsula. 64.6% of the salinity-affected land was identified as being in the extreme saline category. In addition to reducing net arable lands, soil salinization has serious implications for food security and the livelihoods of farmers, potentially impacting the regional and national economy.

Traditional Cambodian food has higher nutrient balances and is environmentally sustainable compared to conventional diets. However, there is a lack of knowledge and evidence on nutrient intake and the environmental greenness of traditional food at different age distributions. The relationship between nutritional intake and environmental impact can be evaluated using carbon dioxide (CO2) emissions from agricultural production based on life cycle assessment (LCA). The objective of this study was to estimate the CO2 equivalent (eq) emissions from the traditional Cambodian diet using LCA, starting at each agricultural production phase. A one-year food consumption scenario with the traditional diet was established. Five breakfast (BF1–5) and seven lunch and dinner (LD1–7) food sets were consumed at the same rate and compared using LCA. The results showed that BF1 and LD2 had the lowest and highest emissions (0.3 Mt CO2 eq/yr and 1.2 Mt CO2 eq/yr, respectively). The food calories, minerals, and vitamins met the recommended dietary allowance. The country’s existing food production system generates CO2 emissions of 9.7 Mt CO2 eq/yr, with the proposed system reducing these by 28.9% to 6.9 Mt CO2 eq/yr. The change in each food item could decrease emissions depending on the type and quantity of the food set, especially meat and milk consumption.
