Land Clearance

One of the measures to eliminate the consequences of the Chernobyl accident was the exclusion of highly contaminated land from agricultural use. Due to the positive dynamics of the radiation situation, the issue of land return becomes relevant. However, in the period of exclusion of these lands the land clearance degradation processes were developing. The second part of the article is devoted to the issue of economic evaluation of the expediency of land return and the mutual coordination of the results of separate stages of complex ecological and economic evaluation. The research was carried out in Mogilev branch Institute of radiology (Republic of Belarus).

Acacia axillaris Benth. had been recommended for downgrading from a conservation status of vulnerable to one of rare in response to changed knowledge of its distribution. Ecological investigations of its phytosociology, stand structure, germination requirements, soil seed store and response to fire and disturbance indicate, however, that it is susceptible to elimination by fire regimes that allow the survival of most of its co-occurring species and most other Australian species of Acacia. The species is also vulnerable to land clearance and weed competition in the lowland part of its range, which is largely on private land.A. axillaris may be a refugial species, better suited to glacial Tasmania than to interglacial Tasmania. On ecological evidence, the species should retain its conservation status of vulnerable to extinction.

Stone mortars and pestles are distributed across New Guinea, but few have been found in West Papua. As they are now securely dated to the Mid-Holocene, their distribution can be used as the basis for modelling Mid-Holocene population concentrations. Artefacts with elaborate morphologies also allow the modelling of social interaction. The declining availability of the Castanopsis nut following land clearance would have played a major role in the abandonment of mortars and pestles in the highlands. Decreasing coastal connectivity due to the infilling of the Sepik-Ramu inland sea may have also played a role in this abandonment. The continued availability of canarium and coconuts in coastal areas allowed the making of nut and starch puddings to continue. However, the pottery bought by Austronesian speakers (Lapita) would have allowed tubers to be steam-cooked, and the softer result probably led to stone versions of mortars and pestles being abandoned and replaced with wooden versions.

The recent study of Kis-Mohos Tó lake in Hungary reveals an important sequence of prehistoric landscape changes from the earliest land clearance to the early Middle Ages. The recognition of land degradation, through the application of new analytical methods, forms an important part of the discussion.
