The Impact

This paper develops a lexicographic optimization model to allocate agricultural and non-agricultural water footprints by using the land area as the influencing factor. An index known as the water-footprint-land density (WFLD) index is then put forward to assess the impact and equity of the resulting allocation scheme. Subsequently, the proposed model is applied to a case study allocating water resources for the 11 provinces and municipalities in the Yangtze River Economic Belt (YREB). The objective is to achieve equitable spatial allocation of water resources from a water footprint perspective. Based on the statistical data in 2013, this approach starts with a proper accounting for water footprints in the 11 YREB provinces. We then determined an optimal allocation of water footprints by using the proposed lexicographic optimization approach from a land area angle. Lastly, we analyzed how different types of land uses contribute to allocation equity and we discuss policy changes to implement the optimal allocation schemes in the YREB. Analytical results show that: (1) the optimized agricultural and non-agricultural water footprints decrease from the current levels for each province across the YREB, but this decrease shows a heterogeneous pattern; (2) the WFLD of 11 YREB provinces all decline after optimization with the largest decline in Shanghai and the smallest decline in Sichuan; and (3) the impact of agricultural land on the allocation of agricultural water footprints is mainly reflected in the land use structure of three land types including arable land, forest land, and grassland. The different land use structures in the upstream, midstream, and downstream regions lead to the spatial heterogeneity of the optimized agricultural water footprints in the three YREB segments; (4) In addition to the non-agricultural land area, different regional industrial structures are the main reason for the spatial heterogeneity of the optimized non-agricultural water footprints. Our water-footprint-based optimal water resources allocation scheme helps alleviate the water resources shortage pressure and achieve coordinated and balanced development in the YREB.

Goafs formed in mine-out areas threat the underground mines owing to possibilities of rock burst and surface subsidence. This paper aims to discuss the feasibility, design and construction of waste rock backfill in abandoned stopes. Based on goafs distribution and stabilities in the White Bull Mine, rock backfill system with a total volume of 362,000 m3in 8 gobs was designed and carried out. The system included technologically and economically feasible stopes, conveying equipments of tramcars, rock transfer by electric rakes, haulage network and mining workings. Field effects showed that rock backfill was applicable to control potential hazards. With rock filling, goaf utilization rates ranged from 60% to 70%, which helped to control adjacent rock movement, eliminate rock burst and surface subsidence. Additionally, backfill construction reduced the lift and transportation costs of rocks by about 50%, which further lowered the land usage of surface dumping.

Although increasing numbers of research papers regarding biochar are being published worldwide, in some countries growing interest in biochar has only recently been observed; this is true of Poland. We analysed information on biochar research in Poland alongside lessons learned elsewhere in order to identify the significant opportunities and risks associated with biochar use. This data fed into a GIS-based multicriteria analysis to identify areas where biochar application could deliver greatest benefit. We found that 21.8% of agricultural land in Poland has at least moderate indication for biochar use (soil organic matter below 2% and ph below 5.5), while 1.5% was categorized as a priority as it also exhibited contamination. Potential barriers identified included biomass availability and associated risks of indirect land-use change due to possible national and transnational biomass production displacement. Biochar use could have positive global consequences as a climate change mitigation strategy, particularly relevant in a country with limited alternatives. Scaling up a mitigation technology that is viable on account of its co-benefits might be cost-effective, which could, in turn, adjust national perspectives and stronger involvement in developing mitigation policies at the regional level. Biochar has much promise in temperate conditions and further research should therefore be assigned to explore biochar’s environmental and socio-economic impacts.

Abstract Amdal regulation on mining exploitation according to Law No. 32 of 2009 aims to protect and manage the environment properly. This research reveals the paradox of EIA at the micro level (a case study) supporting the neoliberal agenda and facilitating economic development. This study aimed to explore how the practice of compensation for agricultural land at the scoping stage in the preparation of mining Amdal documents. The research was conducted in Mulawarman village, Kutai Kartanagara district, East Kalimantan province in the period 2004-2013. Historically, in the 2004-2013 period, Kutai Kartanegara Regency was the most massive in issuing mining business permits in Indonesia. The results of the study indicate that there was weak legal protection for agricultural land owners and unequal negotiation practices between companies and land owners without government supervision. The practice of compensation is a development tool rather than an environmental protection tool..

Terai region of West Bengal fall under high rainfall region but 90% rainfall occurs in kharif season and drought observed during rabi season.  NICRA project started in the Cooch Behar District during 2011. The project area and plan of work were selected on the basis of participatory rural appraisal method. The experimental trial was conducted from 2011 to 2019. The objective of the experiment was to development of sustainable irrigation system through renovation of pond and its impact on crop production. It was found from the study that pond renovation has potential impact on increasing crop yield, cropping intensity, copping system and area of irrigation.

Urban sprawl has been plaguing Western European and American cities for the last 70 years. One has fought against this phenomenon all over the world with a combination of strategic planning and urban regulations, focusing on growth management, sustainable development and preservation of farmland. East European cities, Romanian cities included, have been rapaciously consuming the free natural and agricultural land around them, without long-term development policies. The aim of this paper is analyzing urban sprawl around Timișoara and finding efficient ways of economizing urban and rural land. The article is based on several urban studies, statistical and traffic data showing the magnitude of the phenomenon and its dramatic effects on the environment.The European Union required to recent members to follow the path set by the developed countries, even if their economies have a system more or less centralized inherited from communism. It is still unclear who should be responsible for urban planning; the rules and regulations are made along the way, while the investors’ pressure is huge. Meanwhile extended rural and agricultural land might be destroyed. Most politicians do not acknowledge this problem as they approve further expansion into farmland without any previous planning. This paper might be just tackling this subject, but its target should be making urban sprawl more visible, understanding its dimension and dramatic effects around Romanian cities.
