Abstract. In order to understand better if and where erosion rates calculated using in situ 10Be are affected by contemporary changes in land use and attendant deep regolith erosion, we calculated erosion rates using measurements of in situ 10Be in quartz from 52 samples of river sediment collected from three tributaries of the Mekong River (median basin area = 46.5 km2). Erosion rates range from 12 to 209 mm kyr−1 with an area-weighted mean of 117 ± 49 mm kyr−1 (1 standard deviation) and median of 74 mm kyr−1. We observed a decrease in the relative influence of human activity from our steepest and least altered watershed in the north to the most heavily altered landscapes in the south. In the areas of the landscape least disturbed by humans, erosion rates correlate best with measures of topographic steepness. In the most heavily altered landscapes, measures of modern land use correlate with 10Be-estimated erosion rates but topographic steepness parameters cease to correlate with erosion rates. We conclude that, in some small watersheds with high rates and intensity of agricultural land use that we sampled, tillage and resultant erosion has excavated deeply enough into the regolith to deliver subsurface sediment to streams and thus raise apparent in situ 10Be-derived erosion rates by as much as 2.5 times over background rates had the watersheds not been disturbed.

The issue of ensuring the sustainable development of mankind today is recognized as one of the most pressing issues facing society. The purpose of the study is to generalize the features of sustainable land using, identify the main problems of sustainable use of agricultural land in Ukraine and the key ways to solve them. The paper summarizes the key stages of the formation of prerequisites for sustainable land using, systematizes documents and events to create a model of sustainable development, highlights the basic principles and goals of sustainable agricultural land use, in accordance with the concept of sustainable development. The authors emphasize that the practical implementation of the concept of sustainable agricultural land use requires prioritization of agricultural land, especially environmental, as well as increasing the responsibility of agricultural businesses for disturbing the ecological balance and excessive anthropogenic pressure on land resources. It is noted that in Ukraine there is an irrational structure of land use, which is environmentally dangerous. The main problems of sustainable agricultural land use development are highlighted. The authors note that in recent years in Ukraine there have been negative trends in the development of processes that significantly affect agricultural land use. The most acute environmental problems are the development of degradation processes in the arable lands of Ukraine, which are continuous, regional or local in nature. The authors argue that the decline in the natural potential of agricultural land in Ukraine is becoming an even more serious threat to the sustainable development of land use than environmental problems. The priority directions of development of sustainable land use in Ukraine are offered, which will allow passing to the model of sustainable agricultural land use.

The purpose of the study is to determine the causes of conflicts in the land use in land-hungry regions and to develop optimal solutions in land disputes. The research is based on the field data, collected in land- hungry regions of Russian Caucasus and historical data for same regions. We analyze the data acquired and use the system approach for developing a classification for studied conflicts. It supports the thesis that the agricultural land ownership is critical for the development of a stable regional system of agricultural production. In the majority of Russian regions land reform has been already carried out. Thus, market mechanisms for the functioning and realization of the right to use and possession of agricultural land are in effect. But in North Caucasus republics, institutionalization of land ownership is still vague. As a result, the number of disputes and conflicts in land use is growing. In the article, we carried out a classification of conflicts in land use and the analysis of land conflicts in the republics of the North Caucasus.
