Every year a considerable number of human lives and elephants have been lost due to HEC. The study was carried out in Dimbulagala Divisional Secretariat area, which has the highest level of HEC in Polonnaruwa District of Sri Lanka. The objectives of the study were to identify the causes for the intensification of HEC, its consequences and to determine suitable mitigation measures.
During the study, visits were carried out in Dimbulagala Divisional Secretariat area and data were collected through observations, discussions, and questionnaires. A study visit was carried out in the Shiretoko Peninsula in Hokkaido, Japan to understand the Human-Brown bear conflict management measures. International approaches to preventing and mitigating the HEC were identified by reviewing published research articles to determine suitable HEC mitigation actions for Dimbulagala.
Poor land-use pattern, loss of forest cover, expansion of agricultural land and disturbance of elephant behavior due to human activity were identified as the main causes, whereas human death, property and crop damage were identified as the consequences. Mitigation measures are suggested under three categories depending on the timing of their implementation. Crop insurance, crop regime modification, and public awareness-raising are recommended as short-term measures, while electric fencing, translocation, domestication, eco-tourism development and habitat enrichment of elephants are suggested for the medium-term. Long-term actions include the implementation of land use policy and control of the elephant population.

The occurrence and preliminary ecological risk of 12 (11 antibiotics and 1 antiepileptic drug) pharmaceuticals were investigated for the first time in the surface water of the old Brahmaputra River, where open-water-fed aquaculture activities are being practiced in Bangladesh. The pharmaceuticals were quantified by high-performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS), operated with positive electrospray ionization (ESI) and a multiple reaction monitoring (MRM) mode. Nine pharmaceuticals were detected in the river surface water, whereas three were below the limit of detection (LOD). Metronidazole was detected in all the samples with concentrations ranging from 0.05 to 13.51 ng L. Trimethoprim had the second highest frequency of detection (95%) with the highest concentration (17.20 ng L). The ranges of concentration and detec...

However, these models assume that cost for seed crop is proportional to the cost of male flowers. This is ...
