Landscape-Based Mitigation Strategy for Addressing Human-Elephant Conflict in Horowpathana, Sri Lanka: A Comprehensive Study

Horowpathana has been identified as a hotspot of human-elephant conflict in Sri Lanka's north-centralprovince, where quick intervention is required. But Sri Lanka never had a consolidated action plan toaddress the problem. This study deals with the question of how landscape architects can contribute tomitigating the problem in the area. It aims to create a design proposal that facilitates elephant requirementsand offers functions and recreation for the residents at the same time. The design is based on the method ofanimal-centred design. The study demonstrates that such conflicts can be resolved through preciselandscape design that considers the issue on the specific site. Effective implementation requires stronggovernance structures and policy support from stakeholders like governmental institutions, conservationorganizations, and academics. Collaboration between infrastructure developers and conservationists canreduce the harmful effects of development projects on wildlife by employing proper design methodologiesand undertaking further research to assure establishment efficacy

POTENTIAL FOR ECO- TOURISM AS A SUSTAINABLE APPROACH TO UTILIZE RESOURCES IN UP-COUNTRY TEA ESTA TES IN SRI LANKA

In the context of tea industry in Sri Lanka, ecotourism has been recognized asan economically viable, environmentally friendly, and socially acceptablenon-crop diversification mechanism to increase profits according to AsianDevelopment Bank report, 2000.The purpose of this study was to assess the potential for ecotourism inupcountry tea plantations in Sri Lanka. Six estates, namely: (1) Hellbodda;(2) Kaloogala; (3) Melfort; (4) Rothschild; (5) Sanquhar, and (6) Sogama thatare located in the Pussellawa plantation sub district have been selected as thecases.Collection of data was characterized by: (1) a field survey at each location toidentify the availability of potential resources for ecotourism (e.g. attractions,infrastructure); (2) a community survey with the estate households; (3) aseries of personnel interviews with the estate management, and (4)questionnaire-based surveys with potential local and foreign tourists to thesesites.The information collected through the field, community, and managementsurveys were used to develop an index - "Tourism Potential Index" (TPI),that explain the capacity of each estate to develop ecotourism. The resultsbased on the TPI suggest that the best location for ecotourism was theRothschild followed by Hellbodda, and Sogama. The results also show thatabout 75% of estate community was in favor of implementing an ecotourismproject, and about 84% and 78% of foreign and local tourists, respectively,are willing to visit such a project. The results highlight the necessity ofimplementing sustainable alternative projects to enhance the quality of life ofthe estate community.

Etiology of Severe Acute Watery Diarrhea in Children in the Global Rotavirus Surveillance Network Using Quantitative Polymerase Chain Reaction

Background: The etiology of acute watery diarrhea remains poorly characterized, particularly after rotavirus vaccine introduction. Methods: We performed quantitative polymerase chain reaction for multiple enteropathogens on 878 acute watery diarrheal stools sampled from 14643 episodes captured by surveillance of children <5 years of age during 2013-2014 from 16 countries. We used previously developed models of the association between pathogen quantity and diarrhea to calculate pathogen-specific weighted attributable fractions (AFs). Results: Rotavirus remained the leading etiology (overall weighted AF, 40.3% [95% confidence interval {CI}, 37.6%-44.3%]), though the AF was substantially lower in the Americas (AF, 12.2 [95% CI, 8.9-15.6]), based on samples from a country with universal rotavirus vaccination. Norovirus GII (AF, 6.2 [95% CI, 2.8-9.2]), Cryptosporidium (AF, 5.8 [95% CI, 4.0-7.6]), Shigella (AF, 4.7 [95% CI, 2.8-6.9]), heat-stable enterotoxin-producing Escherichia coli (ST-ETEC) (AF, 4.2 [95% CI, 2.0-6.1]), and adenovirus 40/41 (AF, 4.2 [95% CI, 2.9-5.5]) were also important. In the Africa Region, the rotavirus AF declined from 54.8% (95% CI, 48.3%-61.5%) in rotavirus vaccine age-ineligible children to 20.0% (95% CI, 12.4%-30.4%) in age-eligible children. Conclusions: Rotavirus remained the leading etiology of acute watery diarrhea despite a clear impact of rotavirus vaccine introduction. Norovirus GII, Cryptosporidium, Shigella, ST-ETEC, and adenovirus 40/41 were also important. Prospective surveillance can help identify priorities for further reducing the burden of diarrhea
