Agricultural Land Management Options Following Large-Scale Environmental Contamination: Evaluation for Fukushima Affected Agricultural Land

Author(s):  
Hildegarde Vandenhove

The accident at the Fukushima Daiichi Nuclear Power Plant has raised questions about the accumulation of radionuclides in soils, the transfer in the foodchain and the possibility of continued restricted future land use. This paper summarizes what is generally understood about the application of agricultural countermeasures as a land management option to reduce the radionuclides transfer in the food chain and to facilitate the return of potentially affected soils to agricultural practices in areas impacted by a nuclear accident.

The high land conversion rate to other sectors has led the government to issue Law No. 41 in 2009 concerning Protection of Sustainable Agricultural Land (SAL). The study aims to identify the distribution of sustainable agricultural land uses and determine agricultural land-use changes from 2016 to 2019 and determine farmers' understanding of sustainable agricultural land control in the strategic area of Garut Regency. We overlaid the land use maps of Garut Regency in 2016 and 2019 and conducted a survey using an online questionnaire with a Google form. The research location is in five districts in Garut Regency. The results showed no land conversion in the area of existing sustainable agricultural land in Garut Regency. The total rice field area is 6,081 hectares, with about 24% is sustainable agricultural land. From 2016 to 2019, the rice field area decreased by 12 hectares. The farmers' awareness of SAL tends to be more likely aware of the sustainable agricultural land area, as many as 39% of farmers aware of sustainable agricultural land. The incentives given to farmers who control sustainable agricultural land are tax deduction, agricultural infrastructure supply, agricultural production facilities subsidies, and land certification facilities. The majority of the respondents are aware of these incentives. In conclusion, no sustainable agricultural land is converted, even though changes occur in non-sustainable agricultural land. The impact of this study is for recommendations to the government in sustainable agricultural land management.

The study of sustainable land use in agriculture is a growing direction of research worldwide. The relevance of this topic is related to the large-scale degradation and increasing multifun-ctionality of agricultural land. According to scientists, unsustainable land use is largely due to the shortcomings in land management. In the Russian Federation, this scientific direction is less developed, especially in terms of policy instruments at the regional level. The aim of the work is to pro-pose instruments for sustainable land use in the northern region based on the study of the works of foreign and Russian scientists and the assessment of the effectiveness of agricultural land management mechanisms in the Komi Republic. The object of the study is the agricultural land use of the Komi Republic. The methodological basis of the research is as follows: monographic method, analysis and synthesis, systematization and generalization, quantitative methods of statistical information processing. The paper examines the current agrarian land policy in Russia and its mechanisms, and reveals its weak focus on achieving sustainable land use. The classification of the instruments of the policy of sustainable land use is clarified and supplemented with the following elements of social sustainability: protection of cultural and social values of society, preservation of traditional land use and ancient settlements, use of local knowledge about land use activities, and environmental justice. Based on the analysis of the agricultural land use of the Komi Republic and its regulatory instruments, the use of elements of sustainable land use aimed at supporting soil fertility through agroforestry, agroforestry reclamation, and the development of agrobiology is proposed. The introduction of ʺgreen public procurementʺ, the expansion of measures to inform and train best practices of land use are recommended.

Land erosion in wilderness, conservation, and recreational, areas may be accelerated by certain non-agricultural land management practices. Examples from the Natal Drakensberg are used to demonstrate how certain types of land modification—such as burning, the construction of unpaved access roads, and the creation of paths and tracks—may result in rapid acceleration of erosion rates.

This study explores the root causes of the Fukushima Daiichi disaster and discusses how the complexity and tight coupling in large-scale systems should be reduced under emergencies such as station blackout (SBO) to prevent future disasters. First, on the basis of a summary of the published literature on the Fukushima Daiichi disaster, we found that the direct causes (i.e., malfunctions and problems) included overlooking the loss of coolant and the nuclear reactor’s failure to cool down. Second, we verified that two characteristics proposed in “normal accident” theory—high complexity and tight coupling—underlay each of the direct causes. These two characteristics were found to have made emergency management more challenging. We discuss how such disasters in large-scale systems with high complexity and tight coupling could be prevented through an organizational and managerial approach that can remove asymmetry of authority and information and foster a climate of openly discussing critical safety issues in nuclear power plants.

In SWAT and SWAT+ models, the variations in hydrological processes are represented by Hydrological Response Units (HRUs). In the default models, agricultural land cover is represented by a single growing cycle. However, agricultural land use, especially in African cultivated catchments, typically consists of several cropping seasons, following dry and wet seasonal patterns, and are hence incorrectly represented in SWAT and SWAT+ default models. In this paper, we propose a procedure to incorporate agricultural seasonal land-use dynamics by (1) mapping land-use trajectories instead of static land-cover maps and (2) linking these trajectories to agricultural management settings. This approach was tested in SWAT and SWAT+ models of Usa catchment in Tanzania that is intensively cultivated by implementing dominant dynamic trajectories. Our results were evaluated with remote-sensing observations for Leaf Area Index (LAI), which showed that a single growing cycle did not well represent vegetation dynamics. A better agreement was obtained after implementing seasonal land-use dynamics for cultivated HRUs. It was concluded that the representation of seasonal land-use dynamics through trajectory implementation can lead to improved temporal patterns of LAI in default models. The SWAT+ model had higher flexibility in representing agricultural practices, using decision tables, and by being able to represent mixed cropping cultivations.

Fundamental reforms are being carried out in many spheres of the national economy in our republic. In particular, the development of the agricultural sector in the liberated territories is one of the main goals today. It is very important to reorganize the agrarian sector on the basis of the adopted laws, to use lands efficiently, and to organize agricultural land management in a modern form. The article studied the agrochemical properties of meadow-gray soils in the territory of Aghdam region and determined that the 0-100 cm layer of soils is poorly supplied with common and active forms of nitrogen, phosphorus and potassium elements. Key words: Mil-Garabagh, Ağdam district, nitrogen, phosphorus, potassium, meadow-gray soils, cadastre, fertility
