“…The root systems of broad-leaf trees are extensive, a factor that helps prevent landslides. However, along the rivers are settlements and arable land (hazelnut farms) (Demir et al 2015b), which has led to an increase in landslide occurrences, particularly where land has been cleared on the steep banks ( Fig. 7) and roots and other physical barriers have been removed (Pandey et al 2007).…”

“…The average precipitation in this region is 822 mm, considerably more than that for Turkey as a whole (643 mm). As in the rest of the Black Sea Region, subsistence/semi-subsistence farming is common, but there is little large-scale commercial farming as a result of the topography and land ownership issues (Inan et al 2011;Demir et al 2015b). Areas north and south of the lake have seen major infrastructure development with the construction of buildings and roads.…”

“…Moreover, a considerable amount of fertile land is carried away yearly by rivers as a result of soil erosion, which leaves the remaining fertile land exposed to increased erosion and landslides (Irvem et al 2007;Aydin and Tecimen 2010). Such environmental hazards have been exacerbated by disorganised and traditional land use practices in rural areas, where planning and land management regulations are often disregarded (Demir et al 2015b).…”

“…From 2005 to 2008, 178 landslides occurred in areas with heavy rainfall and steep slopes (Bayrak and Ulukavak 2009). Several landslide-related studies have been conducted in the last decade for this region of the Black Sea (Demir et al 2015b; Bayrak and Ulukavak 2009;Yalcin 2007;Nefeslioglu et al 2008;Yalcin et al 2011;Reis et al 2009), with deforestation, population increase, extreme precipitation, topography, geology, river networks and land use being some of the observed factors that contribute to landslide activity. Widespread agriculture (hazelnuts and tea are cultivated) makes the Trabzon province an economically important region for Turkey.…”

Of the natural hazards in Turkey, landslides are the second most devastating in terms of socioeconomic losses, with the majority of landslides occurring in the Eastern Black Sea Region. The aim of this study is to use a statistical approach to carry out a landslide susceptibility assessment in one area at great risk from landslides: the Sera River Basin located in the Eastern Black Sea Region. This paper applies a multivariate statistical approach in the form of a logistics regression model to explore the probability distribution of future landslides in the region. The model attempts to find the best fitting function to describe the relationship between the dependent variable, here the presence or absence of landslides in a region and a set of independent parameters contributing to the occurrence of landslides. The dependent variable (0 for the absence of landslides and 1 for the presence of landslides) was generated using landslide data retrieved from an existing database and expert opinion. The database has information on a few landslides in the region, but is not extensive or complete, and thus unlike those normally used for research. Slope, angle, relief, the natural drainage network (including distance to rivers and the watershed index) and lithology were used as independent parameters in this study. The effect of each parameter was assessed using the corresponding coefficient in the logistic regression function. The results showed that the natural drainage network plays a significant role in determining landslide occurrence and distribution. Landslide susceptibility was evaluated using a predicted map of probability. Zones with high and medium susceptibility to landslides make up 38.8 % of the study area and are located mostly south of the Sera River Basin and along streams.

“…In preindustrialized societies and currently where limited-resource farmers do not rely upon intensive use of external inputs to maintain fertility, producers must avoid land overuse that results in land degradation (see references in Aref and Wander (1997) and King (2004)) by implementing a variety of practices. Low input or extensive production systems that rely on rest or rotation, strategic stocking or grazing, slash and burn, fallowing, green manuring or diversification become unsustainable if the area required to support farmers is inadequate, or when economic conditions prevent the purchase of supplements needed to overcome limits (Demir et al, 2015;Tauger, 2010). While these traditional systems are often seen as static, some of the earliest producer organizations were created to protect their rights and help them gain access to new ideas and practices.…”

Understanding how to promote farmers’ use of carbon (C) centric practices known to increase soil C sequestration is needed to design information systems and orient policy, investment and environmental markets. Farmers undertake individual and collective actions using techniques that have varied over time and space according to land potential, farming systems, values and, evolving political and environmental contexts. Interviews with US Midwest conservation, conventional and organic grain farmers suggest market outlet most influences C stewardship. The number of samples needed to verify C sequestration targets by direct soil sampling is high and may temper interest in C markets; however, direct verification can reasonably be achieved by pooling data from multiple farms. Valorization-mechanisms and cooperative efforts lower costs and help individuals address large-scale issues like climate change and indirectly influence unwanted impacts of farm-size-expansion and competition for land, but do not consider benefits to family and community well-being that matter to farmers.
