Trophic interactions in the coastal ecosystem of Sri Lanka: An ECOPATH preliminary approach
Provedor de dados: 5
Autores: Haputhantri, S; Villanueva, Ching-maria; Moreau, J.
This study attempts to assemble and summarize existing information in order to build a general representation of the trophic interactions within the shallow coastal ecosystem of Sri Lanka. A multispecific ecosystem-based approach on trophic relationships and their possible variations was performed using ECOPATH. Thirty-nine functional groups were considered representing all trophic levels in the food web.   Time-dynamic simulation was carried out using the ECOSIM routine to evaluate the impact of the 1998 El Nino event on key functional groups. Results show that the time needed for any impacted functional group to recover to its initial abundance increased with the trophic level. Two time-series data sets derived from commercial catch and effort statistics...

Cranial Capacity in an Adult Sri Lankan Population: Sexual Dimorphism and Ethnic Diversity
Provedor de dados: 77
Autores: Ilayperuma,I.
Cranial capacity exerts a close correlation with the volume of the brain. A large body of evidence shows a clear racial variation in cranial dimensions. Therefore detailed knowledge of the population specific data on biometric features of the cranial cavity is important in the study and comparison of the crania of populations from different racial backgrounds, assessing growth and development of an individual and in the diagnosis of any abnormalities of cranial size and shape. Despite its significance, little is known concerning the cranial capacity in Sri Lankans. Hence, the present study was undertaken to establish the cranial capacity in an adult Sri Lankan population. A total of 210 subjects with an age span of 20-23 years were included in the study....

On the Prediction of Personal Stature from Cranial Dimensions
Provedor de dados: 77
Autores: Ilayperuma,Isurani.
Dimensional relationship between body segments and stature has been the focus of scientists for many years. All such studies were based on the fact that body segments exhibit consistent ratios relative to the stature and these ratios are linked to age, gender and race. Racial characters are best defined in the skull. Therefore, prediction of stature from cranial remains is vital in establishing the identity of an unknown individual. Despite its significance, little is known concerning the cranial dimensions in Sri Lankans. Hence, this study was designed to investigate the relationship and to propose a gender and age specific linear regression model between the cranial dimensions and height of an individual. A total of 400 subjects with an age span of 20-23...

An investigation into the taxonomy of Dendrelaphis tristis (Daudin, 1803): revalidation of Dipsas schokari (Kuhl, 1820) (Serpentes, Colubridae)
Provedor de dados: 16
Autores: Rooijen, J. van; Vogel, G.
The taxonomic status of the colubrid snake Dendrelaphis tristis (Daudin, 1803) was investigated on the basis of morphological data taken from 64 museum specimens. Univariate and multivariate analyses of these data reveal that Dendrelaphis tristis is composed of two species. One of these species agrees with the description of Dipsas schokari Kuhl, 1820 which is revalidated in the combination Dendrelaphis schokari (Kuhl, 1820). The syntypes of D. schokari have been lost and a type for D. tristis has never been deposited in a collection. Neotypes are designated and described for both species in order to stabilize the names. D. schokari differs from D. tristis in having a lower number of ventrals and subcaudals, a larger eye, a shorter vertebral stripe and the...

Possible Rumphius specimens detected in Paul Hermann’s Ceylon herbarium (1672–1679) in Leiden, The Netherlands
Provedor de dados: 16
Autores: Andel, T.R. van; Mazumdar, J.; Barth, E.N.T.; Veldkamp, J.F.
Georg Eberhard Rumphius (1627–1702), author of the monumental work Herbarium Amboinense (1741–1755) is seen as the undisputed patriarch of Malesian Natural Sciences. Until recently, it was thought that if Rumphius had collected any specimens, they all had been lost. The recent digitisation and revision of two book herbaria in Leiden collected by Paul Hermann (1646–1695) on Ceylon revealed four specimens with reference to either Rumphius or Ambon in Hermann’s handwriting: Colocasia esculenta, Gomphrena globosa, Helminthostachys zeylanica and Biophytum sensitivum, of which the latter does not occur in Sri Lanka. Here we discuss the description of these species in both published and unpublished historic works and consider the possibility that they may...

In Sri Lanka coconut poonac, a byproduct produced from the coconut oil production process, is being used for feeding dairy cattle. Though poonac is cheaper than formula feed, it is feared that the bad effects of cattle health due to its high fat content. This study clarified the economic effect of poonac feeding on dairy farming. We conducted interview survey with 40 small-scale farms in Kurunegala District, and analyzed the relationship among poonac feeding, cattle disease rate, raw milk production and dairy farming income by using the multiple regression analysis. The risk of cattle disease increased as poonac feeding. On the other hand, participation in the feeding training was effective in reducing outbreaks of disease in dairy cattle. Moreover, we...

Adjusting Monetary Measures of Poverty to Non-Monetary Aspects: An Analysis Based on Sri Lankan Data
Provedor de dados: 31
Autores: Weerahewa,   Jeevika; Wickramasinghe,   Kanchana.
This paper reassesses the status of poverty in Sri Lanka using a monetary measure which was adjusted for people's perceptions about the social climate.  Data collected by the Sri Lanka Integrated Survey was used to obtain incidences of poverty using cost of basic need (CBN) poverty lines and poverty lines adjusted for people's perceptions.  The results reveal that the poverty measurements significantly differ with the two approaches though poverty ranking remains more or less consistent.

Peasants and plantations in the Sri Lankan tea sector: causes of the change in their relative viability
Provedor de dados: 31
Autores: Herath,   Deepananda P.B.; Weersink,   Alfons.
In contrast to the increasing trend in farm size found in most agricultural sectors, the absolute number of producers and relative share of total production from small farms growing green leaf tea in Sri Lanka have increased significantly over time. The boom in peasant production and the corresponding decline in plantations are due to the same general drivers explaining the increase in farm size elsewhere. Government programs and price effects that reduced revenue uncertainty and relative costs of production have enhanced the competitive position of small farmers relative to large estates.

Open-Cycle Hatcheries, Tourism and Conservation of Sea Turtles: Economic and Ecological Analysis
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo.
Considers the role that tourism-based sea turtle-hatcheries can play in conserving populations of sea turtles by combining economic analysis of markets with ecological parameters. Background is provided on the nature and development of such hatcheries in developing countries, giving particular attention to Sri Lanka. The modelling provided helps with the assessment of the impacts of turtle hatcheries on the conservation of sea turtles and enables ecological consequences of tourism, based on such hatcheries, to be better appreciated than in the absence of such modelling. The results demonstrate that sea turtle hatcheries that operate for tourist purposes can make a positive contribution to sea turtle conservation, but this depends on the manner in which...

Basin-level use and productivity of water: examples from South Asia
Provedor de dados: 31
Autores: Molden,   David J.; Sakthivadivel,   Ramasamy; Habib,   Zaigham.
Discusses and illustrates concepts for identifying ways of improving productivity of water within basins. The results of applying a water accounting procedure to four sub-basins in South Asia (Bhakra in India; Chishtian in Pakistan; Huruluwewa in northern Sri Lanka; and Kirindi Oya in southern Sri Lanka) are presented. The methodology used identifies the quantities and productivity of various uses of water within a basin. This information is then used to identify the water-saving potential, and the means of improving the productivity of the managed supplies.

The Food Stamp Scheme in Sri Lanka: Costs, Benefits, and Options for Modification
Provedor de dados: 31
Autores: Edirisinghe,   Neville.
Many developing countries attempt to assist low-income households to improve their nutritional intake by providing direct or indirect income transfers. The latter are more common and usually take the form of price subsidies on a range of staple foods. Direct transfers, such as issues of food coupons, are not as widely used as price subsidies. In this regard, the case of Sir Lanka is somewhat unusual, for over four decades it followed a policy of subsidizing food prices, and during the late 1970s, this policy was replaced by a direct transfer scheme in the form of food stamp program.  An analysis of the former food subsidy scheme of Sri Lanka was the subject matter of IFPRI Research Report 13, The Impact of Public Foodgrain Distribution on food Consumption...

ANALYZING NEGOTIATION APPROACHES IN NATURAL RESOURCE MANAGEMENT -  A CASE STUDY OF CROP-LIVESTOCK CONFLICTS IN SRI LANKA
Provedor de dados: 31
Autores: Birner,   Regina.
Participatory approaches in natural resource management are increasingly being criticized for their tendency to neglect power relations and conflicts of interests. Negotiation approaches have been proposed as a strategy to overcome such shortcomings. Using the case of negotiations on crop-livestock conflicts in Sri Lanka as an empirical example, this paper proposes to apply the concept of political capital in combination with game theoretical modeling for an analysis of negotiation processes in natural resource management. The model serves to analyze both the incentive structure of the resource users, who are motivated by economic incentives, and the incentive structure of political decision-makers, who are motivated by political interests. The crucial...

Asian Elephants as Agricultural Pests: Damages, Economics of Control and Compensation in Sri Lanka
Provedor de dados: 31
Autores: Bandara,   Ranjith; Tisdell,   Clement A.
Despite growing attention to crop and property damage caused by the Asian elephant, uncertainty exists about the magnitude of this problem. This paper explores the nature and magnitude of this problem of Sri Lanka. An economic analysis of individual farmers’ decisions to control elephants is provided. Government policies to assist farmers to cope with the elephant pest problem are assessed. Appropriate compensation schemes for farmers are seen as potentially more effective for conserving elephants in Sri Lanka than legal prohibitions on killing of elephants. Issues raised have wider relevance than merely to Sri Lanka or Asian elephants.

Use and non-use values of wild Asian elephants: A total economic valuation approach
Provedor de dados: 31
Autores: Bandara,   Ranjith; Tisdell,   Clement A.
The contingent valuation method is often used for valuing environmental goods possessing use as well as non-use values. This paper investigates the relative importance of these values in relation to the existence of the wild Asian elephant.  It does so by analysing results from a contingent valuation survey of a sample of urban residents living in three selected housing schemes in Colombo. We find that the major proportion of the respondents’ willingness to pay (WTP) for conservation of wild elephants is attributable to the non-use values of the elephant. However, differences in the relative importance of these values exist between those who visit national parks and those who do not.  Differences in respondents’ WTP for conservation of elephants are found...

Effects of a Change in Abundance of Elephants on Willingness to Pay for their Conservation
Provedor de dados: 31
Autores: Bandara,   Ranjith; Tisdell,   Clement A.
This paper explores the way in which the stated willingness to pay for the conservation of Asian elephants in Sri Lanka varies with hypothetical variations in their abundance.  To do that, it relies on results from a sample of residents of Colombo.  The willingness to pay function is found to be unusual.  It increases at an increasing rate for hypothetical reductions in the elephant population compared to its current level (a level that makes the Asian elephant endangered) and also increases at a decreasing rate for increases in this population from its current level.  Rational explanations are given for this relationship.  The relationship is, however, at odds with relationships suggested in some of the literature for total economic value as a function of...

Flexible Trade Policies in Agriculture Sectors of Developing Countries: Proposing a Technical Approach for Sri Lanka
Provedor de dados: 31
Autores: Herath,   Anura.
After two decades of liberalized economic policies together with early accession to WTO, Sri Lanka could not achieve the exp ected fast economic growth. Agriculture growth in particular fell sharply. WTO Doha round expects a deeper liberalization. Instead, we will benefit more from being a friend of the "Development Box" and securing flexibility in tariff revisions. In asserting this, the paper analyzes impacts of liberalized policies on agriculture, stress the need for flexible trade policies and formulate a design for self designating Special Products (SP) and Special Safeguard Mechanisms (SSM). The past economic growth favoured mostly urbanised population. Sluggish rural agricultural growth, hurt with increased food imports, was the main cause of this...

Skills, Partnership and Tenancy in Sri Lanka Rice Farms
Provedor de dados: 31
Autores: Desilva,   Sanjaya.
This paper examines whether sharecroppers and fixed-rent tenants in the rice farms of South Asia are distinguished by their farming skills. The idea that fixed-rent contracts are typically given to relatively skilled tenants dates back to the agricultural (tenancy) ladder hypothesis of Spillman [1919]. The screening models [e.g. Hallagan 1978] that have attempted to formalize this idea assume that landlords do not observe the tenants’ skill levels. This assumption is restrictive, and has found little support in empirical studies. The principal-agent model proposed in this paper focuses on the differences between time-intensive and skillintensive labor tasks. I show that tenancy contracts are designed to match the provision of these tasks with the owners of...

After discussing definitions of ecotourism, outlines possible economic and conservational benefits from developing ecotourism or wildlife-based tourism. Identifies possible economic benefits for local communities but also outlines possible economic costs to such communities. Observations are made on the potential of developing ecotourism in the Giant’s Tank/Mannar area. A sufficient market does not always exist for wildlife-based tourism to make it economically viable. Therefore, market analysis should be undertaken before promoting the development of wildlife-based tourism in a locality. A checklist is provided to give some guidance in market appraisal. It is observed that even non-consumptive wildlife-based tourism can have adverse environmental...

Autores: Bandara,   Ranjith; Tisdell,   Clement A.
Results from a CVM survey of willingness to pay for the conservation of the Asian elephant of a sample of urban residents in three selected housing schemes in Colombo, the capital of Sri Lanka, are reported. Face– to–face surveys were conducted using an interview schedule. A non-linear logit regression model was constructed to analyse the respondents’ responses for the payment principle questions and to identify the factors that influence their responses. We investigate whether urban residents’ WTP for the conservation of elephants is sufficient to compensate farmers for the damage caused by elephants, and consequently to raise farmers’ tolerance of the presence of elephants on the farming fields. We find that beneficiaries (the urban residents) could...

Institutional design principles for accountability in large irrigation systems.
Provedor de dados: 31
Autores: Merrey,   Douglas J.
Argues that single irrigation systems managed by autonomous system-specific organizations accountable to their customers, perform better and are more sustainable than those managed by agencies dependent on the government, or by agencies responsible for multiple systems. Selected cases are reviewed and the plausibility of this hypothesis established. General recommendations are made for policy makers designing irrigation reform programs.

Willingness to pay for different degrees of Abundance of Elephants
Provedor de dados: 31
Autores: Bandara,   Ranjith; Tisdell,   Clement A.
This paper presents an application of the contingent valuation method (CVM) to determine how the willingness to pay (WTP) for conservation of Asian elephants varies with hypothetical variations in their population. Results from a CVM survey of a sample of urban residents in Colombo, the capital of Sri Lanka are used for this purpose. We find, consistent with the basic principles of consumer demand theory, the marginal change in the respondents’ WTP amounts is positive but appears to diminish in parallel to the increases in the current wild elephant population (CWEP).  In contrast to theoretical expectations, however, we find that the WTP for preserving this species increases at an increasing rate in relation to decreases in the CWEP. This is probably...

Changing Abundance of Elephants and Willingness to Pay for their Conservation
Provedor de dados: 31
Autores: Bandara,   Ranjith; Tisdell,   Clement A.
This paper explores the way in which the stated willingness to pay for the conservation of Asian elephants in Sri Lanka varies with hypothetical variations in their abundance.  To do that, it relies on results from a sample of residents of Colombo.  The willingness to pay function is found to be unusual.  It increases at an increasing rate for hypothetical reductions in the elephant population compared to its current level (a level that makes the Asian elephant endangered) and also increases at a decreasing rate for increases in this population from its current level.  Rational explanations are given for this relationship.  The relationship is, however, at odds with relationships suggested in some of the literature for total economic value as a function of...

Visitors' reaction to Pinnawala Elephant Orphanage in Sri Lanka: A Survey
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Bandara,   Ranjith.
Pinnawala Elephant Orphanage (PEO) is a unique captive elephant-based recreation facility in Sri Lanka. Over 35,000 visitors (both local and foreign) visit the PEO per month on average for a variety of reasons. However, little or no attempt has been made to examine their reaction to its activities.  This paper reports preliminary findings from two visitor surveys (one local and one foreign) conducted at the PEO to examine the characteristics of visitors, the satisfaction they gained from the visit, their attitudes towards conservation of the elephant, their reactions to the current facilities available at the orphanage, and their opinions and maximum willingness to pay (WTP) to enter the PEO.  It is found that, although some variations occurred between the...

A Non-Parametric Analysis of Rice Production Efficiency in Sri Lanka
Provedor de dados: 31
Autores: Thibbotuwawa,   Manoj; Mugera,   Amin W.; White,   Benedict.
This article investigates the production efficiency of rice farming in Sri Lanka using cross section survey data of 90 farms. Past studies on rice farming have mostly focused on technical efficiency (TE). Here, we examine technical efficiency, allocative efficiency (AE) and cost efficiency (CE) using the data envelopment analysis (DEA) approach. On average, the farms were 87% technically efficient; irrigated farms were more efficient (88%) than rain-fed farms (82%). Average cost, allocative and scale efficiencies were 73%, 84% and 87%. Bias corrected TE estimate suggests an expected output expansion of 25% with a given input combination in order to become fully efficient as opposed to 16% based on the original estimates. In addition, a second stage Tobit...

The objectives of the research were to identify seed management practices of the combined-system paddy seed producers as well as to examine the contribution and quality of the combined paddy seed supply system compared with the formal and informal systems. The study was carried out in Udaberagama village of Hambantota district in southern province of Sri Lanka during March to June in 2013. Eighty farmers were randomly selected and categorized based on use of paddy seed systems as belonging to either the formal, informal or combined system. A farm interview survey and seed sampling for quality testing were conducted for each farmer. The farmers’ combined system seed production, involved strategies of both formal and informal sector, they use formal sector...

Autores: Kodikara,Kodikara Arachchilage Sunanda; Jayatissa,Loku Pullukuttige; Huxham,Mark; Dahdouh-Guebas,Farid; Koedam,Nico.
ABSTRACT Six wide-ranging mangrove species, Rhizophora apiculata, R. mucronata, Avicennia marina, A. officinalis, Bruguiera gymnorrhiza, and B. sexangula, were selected to study the growth and survival of seedlings under three contrasting salinity treatments over a 30-week period: low (3-5psu), moderate (15-17psu) and high (33-36psu). Seedlings grown under high salinity exhibited significantly lower performance (p&lt;0.05) in survival rates, cumulative shoot height, mean growth rates, mean total leaf area, and mean dry weight, compared to those under low and moderate salinity regimes. The low salinity treatment provided the best conditions for initial establishment and growth of the seedlings of all species until 15-20 weeks of age. However, the same...
