Совершенствование критериальной и оценочной базы комплексного эколого-экономического учета

На современном этапе развития экономических отношений особенно актуальной становится проблема вхождения Украины в мировое сообщество в качестве ее полноправного партнера. В этом отношении неоспоримым является тот факт, что экономические проблемы, решаемые нашим государством, являются не только национальными, но и общемировыми.

Economic valuation for water supply from Merapi Volcano National Park Case study: Kali Kuning sub watershed

The Merapi Volcano National Park (MVNP) is developed based on particular considerations such as protecting ecosystem or preserving certain species. Management of national park will not succeed unless the communities surrounding park support the park itself. However, it will be challenging because the park was established through a ‘top-down’ process. Therefore, it is important to ensure that the surrounding communities are able to derive benefit economically from the park, especially environmental services such as water supply. The goal of this study is to estimate the economic value for water supply from MVNP with Kali Kuning Sub Watershed as the study case. The economic valuation is estimated based on three different land use maps: 2015’s (deforestation), 2025’s (afforestation) and extreme condition which is grassland (without national park). The economic value is approached by market price for water use value. Lastly, cost and benefit analysis based on several scenarios (deforestation, afforestation and ‘without national park’) is implemented. The study shows that afforestation scenario presents the highest economic value from water supply for the surrounding communities as well as the downstream communities

Urban Drainage Management and Flood Control Improvement Using the Duflow Case Study: Aur Sub Catchment, Palembang, South Sumatra, Indonesia

Urban flooding oftentimes staggers the livelihood in an urban area mostly in the lowland parts. The research location is in Palembang, Indonesia with approximately 30% of the urban part is in lowland areas. Aur Sub Catchment is one of the 20 sub catchments of Palembang and located in Silaberanti. The main objective of this research is to improve the current drainage system in order to achieve the optimal design for urban drainage arrangement. This research was developed using Duflow (Dutch Flow) 3.8.3 and ArcGIS 10.1 to schematize the drainage system. As a result, there are three development scenarios established; the first scenario is the existing condition, the second scenario is the extreme condition, and the third scenario is the improvement possibilities of the existing drainage system. There are three different types of improvement: dredging, dike, a pump, and a flap gate.  In conclusion, the most feasible, effective, and efficient alternative for overcoming the flooding in Silaberanti is a flap gate combined with the dike construction in the river.  In addition, the implementation of concept “Living with Water” for the further urban expansion is necessary. These technical and practical approaches need to be combined for solving the flooding in Silaberanti

Sustainable intensification of agriculture for human prosperity and global sustainability

There is an ongoing debate on what constitutes sustainable intensification of agriculture (SIA). In this paper, we propose that a paradigm for sustainable intensification can be defined and translated into an operational framework for agricultural development. We argue that this paradigm must now be defined—at all scales—in the context of rapidly rising global environmental changes in the Anthropocene, while focusing on eradicating poverty and hunger and contributing to human wellbeing. The criteria and approach we propose, for a paradigm shift towards sustainable intensification of agriculture, integrates the dual and interdependent goals of using sustainable practices to meet rising human needs while contributing to resilience and sustainability of landscapes, the biosphere, and the Earth system. Both of these, in turn, are required to sustain the future viability of agriculture. This paradigm shift aims at repositioning world agriculture from its current role as the world’s single largest driver of global environmental change, to becoming a key contributor of a global transition to a sustainable world within a safe operating space on Earth
