The Role of Customary Law in the Forest Preservation in Bali

Abstract

The endeavors to preserve the forest in Bali cannot be isolated from the existence of local wisdom. Customary law, as a decision of Hindu religious leaders in Bali, is one of the local wisdoms which has been maintained by the society. This study examined the values of local wisdom held by indigenous people and reviewed the preservation of forests from a Hindu perspective. This research was conducted in three villages in Bali, namely Tenganan Village, Manggis Sari Village, and Sangeh Village. The residents of these villages believed that forest is a sacred area which must be maintained and preserved properly.

The determinants of economic resilience in rural regions. An examination of the Portuguese case

Abstract

This paper examines the factors that contributed to the economic resilience of rural regions in Portugal following the recent crisis. Portugal has for a long time faced the issue of regionalisation. However, rural regions in Portugal are not homogenous. Rural regions in Portugal are very diverse and experience very different economic realities. This paper adds to the growing body of literature on regional resilience by focusing exclusively on rural regions. Using an adaptation of Martin’s (2012) sensitivity index as a measure of resilience and bivariate analysis this paper examines the determinants of resilience in rural regions. In terms of economic structure, the paper interestingly finds that reliance on agriculture was beneficial while innovativeness hindered resilience. As for measures of social capital, the paper presents some contradictory findings. Higher rates of crime had a negative impact on resilience, however higher political participation also had a negative impact.

The conversion of heights of the benchmarks of the detailed vertical reference network into the PL-EVRF2007-NH frame

Abstract

The paper describes the problem of conversion of heights to the European Vertical Reference Frame 2007 for Poland (PL-EVRF2007-NH). The subject of the study is height data, and especially the detailed vertical reference network. The aim of the article is to present an alternative method of conversion to the one recommended by the Polish Head Office of Geodesy and Cartography. The proposed approach is characterised by a low implementation cost while maintaining the required accuracy.

The publication is illustrated by the case of Kętrzyn district (in the north-east part of Poland). The local reference network was converted from Kronstad’60 to PL-EVRF2007-NH in 2017.

Aluminium in waters of the active exchange zone in the Karkonosze National Park (Western Sudetes, SW Poland)

Abstract

The paper presents the variability of aluminum concentrations in groundwater of the main porous-fissured aquifer and surface waters in the area of the Karkonosze National Park (KPN), covering mainly the upper parts of the Karkonosze Mts. The analysis was based on the results of samplings carried out in the area of the KPN in August 2015 and supplemented with the results of water quality monitoring carried out during the period of 2010–2016 in selected catchments of the Karkonosze Mts. Significant spatial variability of aluminium concentrations was observed, from several dozen to over 1,090 μg/L, increasing along with the height of the measurement points. The highest concentrations were recorded in the ridge zone of the Karkonosze Mts, where the pH is the lowest.
