Opis:
This study aimed to evaluate the carbon and environmental service potential in the natural tourism zone of special purpose forest areas Mount Bromo. The study focused on understanding how this area, with its specific tree compositions and sizes, contributes to carbon absorption and environmental benefits, which can also translate into carbon credits, a form of state revenue. The methodology involved purposive sampling to create observational sample plots (OSP) of varying sizes based on tree diameter. These plots were designed to measure the biomass, carbon potential, and environmental service potential of the trees in a given area. The collected data included the composition of tree species, the number of each type of tree, their diameters, and heights. The study applied specific formulas to determine the potential of biomass, carbon, and environmental services in the area. Key findings revealed a dominance of mahogany trees (83 trees per hectare) among ten identified plant species, indicating a specific but lower biodiversity in this zone. The significant results of the study include the quantification of biomass potential, which was found to be 787.84 tons/ha above-ground and 228.47 tons/ha below-ground, totaling 1016.31 tons/hectare. The study also evaluated the environmental service potential, including CO2 absorption and O2 production. The CO2 absorption capacity of the area was estimated at 1753.04 tons/ha, with a corresponding high O2 production of 1279.72 tons/ha. Additionally, the potential for carbon credits in the area was calculated at approximately 70.12 US$/ha. This research is crucial in understanding how specific forest areas, like special purpose forest areas Mount Bromo, can play a significant role in global environmental sustainability efforts.

Opis:
The distribution of total lithium content with depth was studied in soils of selected forest ecosystems, with regard to their physicochemical properties and possible anthropogenic impact. The six soil profiles, representing forest soils, were selected for the study: Udipsamments formed from sandr sand, eolian sand and alluvial sand, and Haplorthods Humic formed from eolian sand, Dystrochrepts formed from alluvial silt and Eutrochrepts formed from boulder loam. The total Li content was determined after previously dissolving the samples in a mixture of concentrated acids: hydrofluoric and nitric (HF+HNO3). The content of Li in solutions was determined using the FAS method on PU-9100 X Philips spectrometer. The total lithium content in studied soils under investigations occurs in range of 1.63 to 229.68 mg kg-1 and was considerably lower in organic horizons (1.63-8.07 mg kg-1 ) than in mineral (17.58-229.68 mg kg-1). The concentration of lithium in subhorizons of forest litter increases according to the litter decomposition degree (01<0f<0fh). The Li concentrations found in all forest soils formed from sand were much higher than its natural content in surface mineral horizons of arable soils 1.30-56.00 mg kg-1. The total lithium content in studied soils was negative statistically correlated with the content of organic carbon (-0.6062), silt and clay fraction (-0.7131 and -0.6322), hydrolytic acidity (-0.5222), sum of exchangeable bases (-0.6196) and cation exchange capacity (-0.6277).

Can payments for ecosystem services contribute tosustainable development in the Brazilian Amazon?

The Brazilian Amazon supplies the world with several forests ecosystem services, many of which are essential to sustain human life on earth. Nevertheless, the Amazon is threatened by deforestation and degradation implying in reductions on the provision of these. According to economic theory, as ecosystem services are positive externalities and public goods, agents do not take into consideration the costs and benefits of their consumption and production of ecosystem services into their economic decisions. To address this problem payment for ecosystem services – PES – emerged, aiming to provide a source of income to the poor people living in forest areas, stimulating them not to deforest, and making agents who are indebted with the nature pay for their overconsumption of ecosystem services. There is still controversy about possible impacts of the instrument. This article accesses the potentials of PES to contribute to sustainable development in the Brazilian Amazon using the three goals related to sustainable development proposed by the ecological economics theory: efficient allocation, fair distribution, and sustainable scale. The study shows that PES as a pure market approach is unlikely to solve neither the scale nor the distribution problems. Therefore, for PES to achieve sustainable development, markets for ecosystem services should first be constrained by a maximum sustainable scale. Then, measures should ensure fair distribution in second place. Only after these questions have been tackled, it is desirable that agents interact in the ecosystem services markets to lead to an efficient allocation of resources.

Opis:
In the era of dynamic climate change, it is important to have knowledge on the interactions between climatic factors and processes occurring in the soil environment. The present study aimed to determine how slope aspect and altitude above sea level influence carbon and nitrogen accumulation and dehydrogenases activity of forest soils. The study was conducted in the Beskid Żywiecki in the south-facing part of Poland. Soils of the same texture, with similar vegetation species composition, in different altitude variants (600, 800, 1000 and 1200 m above sea level) and different north-facing and south-facing slope aspect were selected for the study. For each height and slope aspect variant, samples were collected from the surface horizons of soils for further analyses. The basic chemical properties and dehydrogenases activity of the soil samples were determined. Carbon and nitrogen stocks in the surface horizons of the soils were calculated. The analyses confirmed the influence of location conditions on the carbon and nitrogen stocks in mountain forest soils. The stock of carbon and nitrogen increased with the height up to 1000 m a.s.l. In the soils at the highest altitude, the reserve of carbon and nitrogen decreased regardless of the slope aspect variant. There were no statistically significant differences in carbon and nitrogen stocks between slope aspect variant. The highest dehydrogenases activity was associated with the organic horizons of the soils at the lowest altitude in height gradient. In our study, higher dehydrogenases activity was observed in the north-facing slope soils, and this finding can be explained by more stable thermal conditions.

Should the whole Białowieża Forest be a national park?

Opis:
In Poland, the stormy discussion on the future of the Białowieża Forest has been ongoing already for a long time. The disputes are mostly focused on seeking answers to two questions: how to protect these unique forest ecosystems and whether forest management threatens their naturalness. The discussion has grown stronger after the recent, enormous outbreak of Ips ypographus in the Forest. The Białowieża Forest has been managed for years with no significant negative effect. However, antagonists of foresters blame forest management for degradation of the Forest’s ecosystems, which is caused by favoring the economic value of timber expected to be harvested in keeping with the management plans of 3 forest districts located in the Białowieża Forest. At any rate, such assumption, has nothing to do with reality. During this discussion the idea to extend the national park for all the Białowieża Forest revived. In this paper, we reviewed the economic, social and ecological dimensions which should be taken into consideration before making a decision on extending the Białowieża National Park. It should be underlined that the Park’s area is already under the strict protection; furthermore, 2/3 of the area of neighboring managed forests are under legal protection (the nature reserves, NATURA 2000, the so-called reference forests, etc.). All things considered, we cannot find any reasonable purpose (ecological, financial or social) for expanding the Park’s area from 10 500 ha (present status) to 62 500 ha (after extension). Also, we are convinced that sustainable forest management conducted in managed parts of the Białowieża Forest, which comprises the fulfillment of all forest functions and services, should not be perceived as a signifcant threat to naturalness of the Forest’s ecosystems.
