Carbon Forests Projects (CFPs) play a significant role in climate change mitigation strategies. Implementation of such projects should bring environmental benefits to companies, as well as contribute to improving the environmental management efficiency in the region. The aim of this paper is to analyze the possibility of developing CFPs as a tool to achieve carbon neutrality, taking into account its environmental and economic benefits. The analysis is undertaken on the example of the Bystrinsky Mining and Processing Plant (MPP), located at the Zabaykalsky Krai (southern Siberia, Russia). The ability of the forest lands to absorb greenhouse gas emissions is assessed using the ROBUL methodology. An important feature of CFPs is the ability to combine a positive environmental effect by contributing to climate change mitigation with strengthening the image of an environmentally friendly company. However, the analysis of CFPs implementation in the example of Bystrinsky MPP shows the excess of costs over benefits. In this regard, more effective projects can be proposed for regions with a high degree of forest cover, such as Zabaikalie. Reducing the risk of forest fires in such regions can have a more tangible environmental impact by preventing additional CO2 emissions. Identifying and comprehensively assessing the environmental and economic impacts of CFPs in the context of carbon neutrality facilitates the selection of the most relevant solutions.

Embung Batur Agung is a source of irrigation for residents around Embung. Depreciation of water in the reservoir occurs due to leakage from the geomembrane layer of the Embung Batur Agung. This study aims to determine the direction of leakage from the reservoir so that appropriate treatment can be carried out. This research was done using hydrogeological analysis and electrical resistivity tomography (ERT) geoelectrical measurements. ERT Geoelectrical measurement uses a dipole-dipole configuration with a spacing of 5 m and 10 m and a line length of 100 m. There are 2 lines in the southwest and southeast of the reservoir. The results of geohydrology analysis, it was found that the aquifer system around the reservoir included in the Gunungsewu aquifer system, and the dynamics of surface groundwater are controlled by faults and fractures. The results of the ERT geoelectrical measurement, there is a low anomaly which can indicate a reservoir leak at 50-60 m on line 1 which is in the southwest of the reservoir. This low anomaly has a vertical pattern as well as there is a fracture which is the cause of the reservoir leak. These low anomaly values range from 4-30 Ωm which can be interpreted as the presence of water that has conductive properties. The results of this study are expected to be used by the local government to handle the leakage of the reservoir.

Daerah penelitian secara administratif berada di Kecamatan Bener, Kabupaten Purworejo, Jawa Tengah. Secara geomorfologi, bentuk lahan daerah tersebut terdiri dari Perbukitan Struktural (S1), Lembah Homoklin (S2), Dataran Alluvial (F1), Tubuh Sungai (F2), dan Dataran Limpah Banjir (F3). Lito-stratigrafi daerah penelitian mulai dari batuan tertua, disusun oleh Satuan Breksi-vulkanik Kaligesing, Satuan Lava-andesit Kaligesing, kedua satuan berumur Oligosen Akhir hingga Miosen Awal, Satuan Batugamping-pasiran Sentolo berumur Miosen Tengah – Pliosen Awal (N14 – N19), dan Satuan endapan alluvial berumur recent. Di daerah penelitian juga dijumpai intrusi andesit berumur Oligosen Akhir – Miosen Awal. Struktur geologi berupa kekar dan sesar secara umum mempunyai orientasi Timurlaut – Baratdaya termasuk reverse left slip fault, dan Baratlaut – Tenggara, merupakan right lateral slip fault. Dari hasil analisis kestabilan lereng terhadap enam lokasi lereng batu berdasarkan metode Markland, diketahui bahwa lereng Wadas berpotensi longsor tipe wedge failure dan planar slide, lereng Kaliwader 1 berpotensi longsor tipe wedge failure, lereng Kaliwader 2 berpotensi longsor tipe wedge failure, lereng Kaliwader 3 berpotensi longsor tipe wedge failure, lereng Kaliwader 4 tidak berpotensi longsor, dan lereng Ngargosari berpotensi terjadi longsoran tipe wedge failure dan tipe planar slide. Penanggulangan longsor dapat dilakukan dengan melakukan pelandaian lereng dan atau metode trap/terasering.

In the vicinity of Penanggungan volcano, Mojokerto regency, east Java, Indonesia, there is an area of cultural heritages, where numerous sites of ancient temples being distributed widely from the flank to near the summit. Fortunately the volcano has been not active anymore since the Holocene epoch. The surrounding area represents variety of volcanicstratigraphy, consisting of Watukosekvolcanic cone, Arjuna - Welirangvolcanic cones represented by Bulak dome, Penanggunganvolcanic cone represented by Bekel dome, Gajahmungkur dome, Genting dome, Bendo dome and Kemuncup dome. Hydrogeologically, the study area performs an aquifer system comprises intergrain, fracture, and intergrain with fracture combination water bearing formations. Some springs occur in the fracture aquifer and the intergrains with fractures aquifer. In general the quality of groundwater is good. Catchment area occupies the summit toward the flank of Penanggungan volcano, whereas runoff area lies on the lowlands. The distribution of ancient cultural sites in the study area can be divided into 5 (five) groups, including cultural sites group at Penanggungan Volcano, cultural sites group at Bekel Volcano, cultural sites group at Genting Volcano, cultural sites group at Kemuncup Volcano, and outer cultural sites group. Finally, based on its volcanic stratigraphy and hydrogeological conditions, the study area can be delineated to be three conservation zones namely zone of protected areas, zone of supporting areas, and zone of unprotected areas. The zone of protected areas is 5,577.78 hectares wide, containing units of protected forest area, critical land area, river border area, springs area, reserve area, cultural site and temple area, area with slope of above 45°, and geological heritage area.
