The paper shows the impact of despatialization on processes of territorial development. The essence of despatialization is the decreasing importance of the spatial factor in the information society, as a result of the use of information and computer technologies, and in particular – the Internet. It creates new challenges for spatial management. Real contact between people and organizations is often replaced with links and information flows, the quality of which is growing and which in many cases eliminate the resistance that spatial distance makes. The multiple effects of this phenomenon modify social relations, at the same time being challenges, but also opportunities to create new tools for managing development policy.

In order to assess the economic benefits of reduced fungicide application for the control of paprika diseases under dryland conditions, on-farm experiments were conducted in the Chinyika Resettlement Area in the Eastern province of Zimbabwe in the 2000/2001 and 2001/2002 seasons. The six fungicide application regimes that were assessed include: weekly interval sprays; Sulphur at 2 weeks after transplanting (WAT) and copper oxychloride-Mancozeb mixture at 6 WAT; spraying after scouting; alternating Sulphur and copper oxychloride- Mancozeb every two weeks; Acibenzolar-s-methyl and unsprayed check. Parameters recorded were disease severity and yield; after harvest an economic analysis was performed. The highest added profit of Z$ 75 930/ha was recorded in the weekly sprayed plots which was not statistically different (p > 0.05) from Z$ 59 410/ha achieved by alternating copper oxychloride and Mancozeb fortnightly at Dengedza site in 2000/2001 season. There were no statistical differences (p > 0.05) between spraying after scouting and Acibenzolar-s-methyl application treatments as they added the least profits of Z$ 990/ha and Z$ 17 250/ha respectively at the same site in the same season. These have serious implications for smallholder farmers in terms of cost savings. Neither were there differences (p > 0.05) in added profits from different spraying regimes at Dengedza site in the 2001/2002 rainy season.

The pressure on the use of water and climate change has caused a decreased availability of water resources in semi-arid areas in the last decades. The Setif Province is one of the semi-arid zones of Algeria as it receives an average less than 400 mm∙year–1. The question of the evolution of demographic pressures and their impacts on water resources arise. By applying WEAP software (water evaluation and planning), the aim is to develop a model of water resources management and its uti-lization, assess the proportion of the resource-needs balance and analyse the future situation of water according to different scenarios. This approach allows to identify the most vulnerable sites to climatic and anthropogenic pressures. The estima-tion of the needs for drinking water and wastewater in the Setif Province has shown that these needs increase over time and happening when the offer is not able to cover the demand in a suitable way. It is acknowledged that there is a poor exploita-tion of water resources including underground resources, which translates into unmet demand in all sites of demand.

This paper describes a unique case of craniosynostosis in a female skull in which sagittal sutures were completely fused by adolescence. Despite sagittal synostosis, the skull was of normal shape and size. Regarding craniometric features, the synostotic normocephalic skull was markedly different than that of scaphocephalic skulls which typically result from premature obliteration of the sagittal suture.

This work aimed to evaluate the potential of Trichoderma asperellum organic extract and its emulsion to control cocoa black pod disease caused by Phytophthora megakarya. Organic extract was obtained after fermentation of T. asperellum and its emulsion prepared by emulsification. The in vitro antimicrobial assays of organic extract and its emulsion were evaluated and the in situ tests were carried out on detached cocoa pods. T. asperellum inhibited the mycelia growth of P. megakarya at the rates of 52% and 100%, respectively, on dual culture and the cellophane plate. This antagonist produced lytic enzymes such as cellulase, amylase, lipase and protease. The organic extract contained alkaloid, flavonoid and phenol compounds. The emulsion obtained was stable. At 100 μg · ml ^-1, the extract and its formulation completely inhibited the mycelial growth of P. megakarya. Similarly, when infected detached cocoa pods were sprayed with extract or emulsion, there was a significant reduction of necrosis both for healing and prevention with the latter being the most efficient. For the preventive tests, the total inhibition was recorded at 3000 μg · ml ^-1 and 1000 μg · ml ^-1, respectively, with crude organic extract and its emulsion· For curative tests, total inhibition was obtained at 4000 μg · ml ^-1 and 3000 μg · ml ^-1, respectively, for preventive and curative tests. There was a significant and positive correlation between the content of biochemical markers and the reduction of necrosis on cocoa pods after treatment with the extract or its formulation. T. asperellum organic extract emulsion could be used as an alternative in the bio- protection of cocoa black pods disease.

Pollen and palcopedological studies have been carried out in parallel for the Stari Bezradychy sequence of the Upper Pleistocene age. The paleoenvironmental information derived from both sets of data is in general well correlated. The section presents a rather complete sequence of the last interglacial-glacial cycle. It includes eight units of the Ukrainian Stratigraphical Framework of the Pleistocene. Interglacial climatic optimum is registered by pollen succession of the Mikulino (Ecmian) type in the climax forest palcosols of Pryluky-Kaydaky pedocomplcx at the base of the sequence, above the Dnieper Glacial deposits. The coldest and most continental environment is recorded in the youngest loess. The soils of Upper Pryluky, Yytachiv and Dofinivka units are correlated with the Early Glacial and four Plcniglacial interstadials. Multiple environmental variations during the Upper Pleistocene recorded in the Stari Bezradychy sequence arc important for study of global climatic changes and interregional correlation. Tentative correlation with marine isotopic stages is proposed.
