From 2009 to 2014 a nationwide effort was made to document, collect, conserve, and characterize wheat landraces grown by Turkish farmers. Spike samples were collected from more than 1600 farmers from 59 provinces, planted as single-spike progenies, and classified into species, subspecies, and botanical varieties (or morphotypes). Altogether, 95 morphotypes were identified representing three species and six subspecies: einkorn wheat (Triticum monococcum L.), emmer wheat [T. turgidum subsp. dicoccon (Schrank) Thell.], cone wheat (T. turgidum subsp. turgidum), durum wheat [T. turgidum subsp.

Since the 1990s, many peatlands that were drained for peat extraction and agriculture in Russia have been abandoned with high CO2 emissions and frequent fires, such as the enormous fires around Moscow in 2010. The fire hazard in these peatlands can be reduced through peatland rewetting and wetland restoration, so monitoring peatland status is essential. However, large expanses, poor accessibility, and fast plant succession pose as challenges for monitoring these areas without satellite images.

The farming system at landscapes preserving and restoring soil fertility of agricultural lands have been developed. Typification of lands was made and the types of agricultural landscapes were allocated: plain, hollow-gully, and gully-field. The analysis of the current structure of arable areas was made and resulted in the assessment of structure's influence on the state of soil fertility. The main degradation processes reducing the fertility of south chernozems were studied. There were proposed the ways of creating the sustainable artificial agricultural landscapes.

Taking into consideration all the data of collectibility of land payments (land tax and rent), the dependence of collectibility of land payments on economic and geographical factors is analysed in municipalities of the Samara region. The factors are defined with the help of mathematical methods, which are closely associated with payments growth from the land area of a municipality and the number of residents. The dependence simulation of the level of land payments on geographical and demographic characteristics has been implemented in a municipality.

Much is reported about the destruction of natural forests and the consequences for global warming, while on the other hand, exotic plantations in some regions struggle to gain public acceptance. The earth's population is projected to rise to around 9 billion by 2050, with a concomitant increase in demand for forest products. Inevitably, forests in general, and managed forest in particular, will be called on to provide an ever-increasing proportion of local supplies and the international wood trade.
