“…Since then, this technique has been extensively used and refined. In this method, pairwise comparison of criteria is used by experts to determine their significance (weight) (12,13). In AHP, selection of the appropriate participants (considering positions and expertise) to represent stakeholders is a critical issue (12).…”

Background: Monitoring of food insecurity is a critical issue for planners and policymakers in the public and private sectors in developing countries. Due to the multifactorial and multidimensional nature of food security and a lack of clarity concerning the causes, specific signs, and consequences of food insecurity, developing a reliable food security index is the major challenge related to monitoring food security. Objectives: The objective of this study was to identify the most appropriate indicators of food security at the provincial level in Iran through the application of an integrated approach including Delphi (classic Delphi) and analytic hierarchy process (AHP) from March to September 2013. Materials and Methods:The sample included 43 senior-level managers and experts at the national and provincial levels from different fields of related sciences; they were selected purposively as Delphi and AHP panel members based on the experts' opinions and snowballing. In the first round of Delphi, out of 103 identified indicators, 38 were selected by the experts; the indicators were ranked in the second round. In the AHP study, 25 experts assigned weights in a pairwise comparison of the 20 indicators that had the highest priority based on the Delphi results. Using AHP matrix calculations, this list of indicators was ranked based on priority. Results: Out of 38 indicators identified in Delphi, 8 were related to the availability dimension, 14 were related to the access dimension, and 16 were related to the utilization dimension. Out of 20 indicators that were ranked in the AHP study, 6 indicators were related to availability, 7 were related to utilization, and 7 were related to access dimensions. However, the indicators related to availability had an overall higher rank compared to indicators related to access or utilization. Conclusions: This study identified and ranked 20 indicators as the most appropriate indicators of food security measurements at the provisional level in Iran.

“…Therefore ensuring the drinking water source area is safe is an important issue in the field of water environment management [1][2][3][4]. The Three Gorges Reservoir Area (TGRA) extends over 600 km, where 17 cities with more than 1700 industrial enterprises are located and thousands of commercial boats transport every year [5][6][7]. Such conditions place drinking water source areas in the TGRA at serious risk of being polluted.…”

Nowadays, the effects of water pollution accidents on water quality safety and regional residents' living have attracted worldwide attention. Therefore, the objective of this research is to propose an early warning and forecasting model and develop a visual system of water quality safety for drinking water source areas in the Three Gorges Reservoir Area under accident conditions. Based on an Instantaneous Point Source Two-dimensional Water Quality Model and the security requirements of water quality, an early warning and forecasting model was presented, and then the system was advanced by a MATLAB platform. In addition, a hypothetical case was also carried out for the Fenghuangshan drinking water source area. Within 0.040 h to 0.096 h after the accident, the water quality could meet the standard, and the warning level was primary and intermediate, sequentially. From 0.096 h to 11.960 h after the accident, the pollutant concentration exceeded the standard, under which conditions advanced warning started. Then the intermediate and primary warnings restarted in sequence until the pollutant concentration decreased to the background value. Therefore, the proposed model could accurately predict the spatial-temporal change trend of pollutant concentration, and the developed system could efficiently realize early warnings and the forecasting of water quality safety.

“…In these studies, first, some researchers adopted mathematical and statistical analysis methods based on historical data to explore the time series evolution characteristics of environmental pollution incidents [5,7,10], and a historical incident database was proposed for long-term risk identification and control [11]. Second, due to the sudden, uncertain and dangerous characteristics of environmental pollution incidents, many scholars focused on the study of risk assessment [12][13][14][15], loss estimation [16,17], simulation [18] and emergency response, and decision-making [19][20][21][22][23] of pollution incidents. There is no doubt that these studies provide a basis for early warning of regional pollution incidents.…”

Spatial-Temporal Hotspot Pattern Analysis of Provincial Environmental Pollution Incidents and Related Regional Sustainable Management in China in the Period 1995–2012

Spatial-temporal hotspot pattern analysis of environmental pollution incidents provides an indispensable source of information for the further development of incident prevention measures. In this study, the spatial-temporal patterns of environmental pollution incidents in China in the period of 1995-2012 were analyzed, using the Spatial Getis-Ord statistic and an Improved Prediction Accuracy Index (IAPI). The results show that, in this period, the occurrence of environmental incidents exhibited a dynamic growth pattern but then dropped and continued to drop after the year 2006, which was considered a crucial turning point. Not coincidentally, this corresponds to the year when the State Council issued its National Environmental Emergency Plan, and following the examination of major incidents, special actions were taken to strengthen the control of incidents and emergency responses. The results from Getis-Ord General G statistical analysis show that the spatial agglomeration phenomenon was statistically significant after 1999 and that the level of spatial agglomeration was rising, while the Getis-Ord Gi * statistical analysis reveals that environmental pollution incidents were mainly agglomerated in the Pan Yangtze River OPEN ACCESSSustainability 2015, 7 14386Delta and Pan Pearl River Delta regions. Accordingly, the spatial-temporal hotspot pattern based on the IAPI values at the provincial scale could be categorized into: stable hotspots, unstable hotspots, and cold-spot areas. The stable hotspots category was further divided into three subtypes: industrial distribution type, industrial transfer type, and extensive economic growth type. Finally, the corresponding measures for sustainable management were proposed: stable hotspots were classified as essential regions requiring the immediate prevention and control of environmental pollution incidents; unstable hotspots were characterized by their need for ongoing and continual prevention measures, and cold-spots were those areas that required strengthened environmental monitoring. Meanwhile, it was identified that a multi-level environmental pollution incident emergency response and regional (incident) joint control plan needed to be well prepared and carried out effectively. To prevent environmental pollution and the regional transfer of pollution from incidents, measures towards achieving regional environmental planning, environmental risk prevention, environmental emergency monitoring and adequate emergency responses must be efficiently implemented.
