Abstract:

Most peatlands in Indonesia have been drained for plantation industries (Oil palm, Acacia) and agricultural purposes in a broad sense. Theoretically, peatlands are extremely sensitive to hydrological changes. The research aimed to elucidate the fact that indigenous farmers avoid deep peatlands for food crop farming. This qualitative and quantitative research has been conducted from 2020 to 2023 in South Sumatra province. It used a field survey method and the data were collected by using a purposive sampling method. There are two main reasons farmers to avoid deep peatlands for cultivating food crops, namely instinctive and latent challenges. The first ones are temporary and technical, so farmers are able to overcome these challenges with a scientific and technological approach. Latent ones are very difficult or impossible to repair and tend to cause the destruction and extinction of peatlands. The government should stop granting concession permits and make deep and very deep peatlands into conservation areas, because of their impact on the environment. Approaches are recommended for sustainable peatland management, namely decentralisation, conservative, protective, and optimal approaches.

Abstract:

Pinus pinaster Aiton (maritime pine) and Pinus radiata D.Don (radiata pine) are both coniferous species not native in Greece, which were artificially installed in Halkidiki, Northern Greece, since the early 1970s. The research was performed to estimate the soil conditions of both conifers in two different areas, where the reforestation has been successful. The best site quality stands were selected, having particularly deep soil. Samples of soil, litter and needles were taken for both species from 16 different sample plots in two sites: Stratoni and Sithonia. From the results, higher concentrations of most soil nutrients, as well as better absorption of P and N by trees, were found in Stratoni for both conifers. Tree dimensions for both conifers are greater in Stratoni, corresponding to the higher nutrient content and an observed higher humidity. The concentrations of nutrients in soil, litter and foliage for each conifer species were assessed according to the literature.

Abstract:

Reclamation is an important activity to support ecosystem recovery after mine closure. The success of this effort depends on plant adaptability to environmental pressure, primarily related to high-acidity soil. However, more information about plant adaptability in reclamation sites is needed, although it is required to determine the alternative species for supporting revegetation efforts. Our study investigated the adaptability of multiple tree species used for coal mining reclamation and assessed their essential role in enhancing biodiversity in the degraded ecosystem. An ecological survey was conducted using a transect line method with a sampling plot size of 20×20 m and an interval from each 50 m. This study found that seven species were used to support the reclamation efforts, i.e., Aleurites moluccana, Archindendron pauciflorum, Artocarpus heterophyllus, A. integer, Durio zibethinus, Hevea brasiliensis, and Mangifera casturi. The survival across species was 78.60−89.39 %, with a height of 64.75−133.94 cm and a diameter of 0.59−1.39 cm. The species diversity was low, with a richness of 0.98 and a heterogeneity of 0.84. These species also had an unbalanced distribution pattern with an evenness index of 0.43. These findings showed that the selected plant species had good adaptability to the environmental conditions of the reclamation site. Although their contribution to biodiversity improvement was still low, there was a positive contribution from these species to biodiversity recovery after the mine closure. Further investigation is still required to monitor the long-term benefits of these species on ecosystem recovery in the reclamation area.

Abstract:

The issue of providing clean water services is fundamental and an important part of the strategy to improve community welfare. Clean water facilities are generally provided by the government, but others are developed and managed by village communities. This research aims to: (1) analyse the supply and consumption of clean water in communities around Wan Abdul Rahman Forest Park (WARFP), (2) identify factors that determine household clean water consumption. This research employs a case study method in a community-based clean water management model around WARFP, in Gedong Tataan Sub-District, Pesawaran District. This research involved 90 ouseholds receiving clean water services. To answer objective 1, data tabulation analysis was used. To answer objective 2 multiple linear regression analysis was used. The study suggests that the clean water received by the community is very abundant, as indicated by the supply of clean water that exceeds household needs. The result also shows that: (1) the average water consumption of people in the study area per capita per day is 189 L with the lowest consumption being 40 L and the highest average consumption being 708 L. There are 29 respondents (32 %) who consume clean water less than the Ministry of Public Works and Housing (MPWPH) standard which is 121 L per capita per day. (2) Factors that influence clean water consumption are water supply, and household revenues. Number of family member and education did not have strong nfluence on water consumption.

Abstract:

The rapid technique for measuring of chlorophyll fluorescence photoinduction is one of mod- ern informative methods for assessing the impact of abiotic factors (temperature, humidity, and environmental light intensity) on physiological traits of photosynthesis responsible for produc- tivity. We explored alterations in activity of different types of chlorophyll fluorescence influenced by above mentioned basic abiotic factors which have been undergoing essential changes in Ukrainian Steppe zone in recent decades. The research object was the black locust, introduced tree species spread widely in the examined region as forest anti-erosion plantings and in the landscaping of industrial towns. To reveal background, stationary, maximum and variable chloro- phyll fluorescence, we used a fluorimeter to measure spectrum of light absorption and reflection by leaves. The output was presented as Kautsky curve that depicted the fluorescence response changes over time. We clarified that the background concentration was minimal at low air tem- perature. With increasing temperature, there was an upward trend in the background fluorescence intensification. The increase in the air humidity caused the opposite effect. With raising tempera- ture, the intensity of maximum fluorescence had the reverse trend compared to the background fluorescence. It decreased when the temperature got higher. Alike the background fluorescence, the stationary fluorescence was minimal at low air temperature, but its rise resulted in the decline in the stationary fluorescence intensity. The research outcomes are methods and mathematical models developed and offered for calculations of different fluorescence types. Statistically signifi- cant relationship between the fluorescence, temperature and light intensity was established. The obtained results allow defining the introduction of Robinia pseudoacacia L. as successful while its resistance to the impact of abiotic environmental factors can be identified as high. It allowed us to specify black locust as the up-to-date species when forming plantings, unless suitable care, management, and control have been fulfilled.
