The processes of salinisation and alkalinisation of soil that caused the formation of different types of saline (halomorphic) soils are characteristic of the northern part of Serbia — the area of Vojvodina. These soils are characterized by poor physical and chemical properties due to a high content of salt and/or adsorbed Na+ ions because of which are being used to a limited extent in agricultural production, and more as pastures.
To exceed in sugar consumption is one of the main causes of overweight and obesity, especially for children and adolescent. However, sugar reduction, especially in baked goods, is challenging due to its effect not only on sensorial properties but also for other quality parameters. Multiple technological strategies to obtain muffins at low sugar content addressed for children were studied.

In this paper, we address the problem of humanitarian aids distribution across refugee camps in war-ridden areas from a network design perspective. We show that the problem can be modeled as a variant of multi-period hub location problem with a particular demand pattern resulted by the user's behavior. The problem has been motivated by a case study of Lebanese experience in Syrian war refugee accommodation. We elaborate on the complexity and real-life constraints and, propose a compact formulation of a mathematical model of the problem.
The no-tillage system combining winter cover crops and crop rotation may increase the efficiency use of soil P and phosphate fertilizer. The objective of this study was to evaluate the effect of three decades of different soil management systems and winter cover crops on the fractions of P in a clayey Oxisol of Paraná State, Brazil. The bi-factorial experiment with three replicates was established in 1986. The main plots consisted of seven winter cover crops. In the subplots, two tillage systems were used: no-tillage and conventional tillage.
Land Degradation (LD) in socio-environmental systems negatively impacts sustainable development paths. This study proposes a framework to LD evaluation based on indicators of diversification in the spatial distribution of sensitive land. We hypothesize that conditions for spatial heterogeneity in a composite index of land sensitivity are more frequently associated to areas prone to LD than spatial homogeneity. Spatial heterogeneity is supposed to be associated with degraded areas that act as hotspots for future degradation processes.
