The Food Stamp Scheme in Sri Lanka: Costs, Benefits, and Options for Modification AgEcon
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...

Land settlement planning issues in irrigation management: A review of experiences in Sri Lanka. AgEcon
Stanbury, Pamela.
This document is meant to present a framework for analyzing the institutions related to water management in a river basin context. The design of the five-country regional study undertaken by IWMI on “Development of Effective Water Management Institutions” provided a new methodology and a framework for river basin studies. It consists of four key components of diagnostic investigations related to water resources management in a river basin, which are interrelated. These key components are the physical system, water accounting, socioeconomic situation and performance. This study design is given in the Study’s Inception Report of 15 June 1999, and the Methodological Guidelines of 1 October 1999. This document takes one step further, and provides a conceptual...

Institutional design principles for accountability in large irrigation systems. AgEcon
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.

Impact assessment of rehabilitation intervention in the Gal Oya Left Bank AgEcon
Amarasinghe, Upali A.; Sakthivadivel, Ramasamy; Murray-Rust, Hammond.
Assesses the impact of rehabilitation interventions on irrigation system performance using time series analysis. The study demonstrates that with proper impact specification and model identification, the nature and magnitude of the impacts of different interventions can be separated from the effects of simultaneous changes in dominant exogenous factors.

Skills, Partnership and Tenancy in Sri Lanka Rice Farms AgEcon
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...

Basin-level use and productivity of water: examples from South Asia AgEcon
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.

Asian Elephants as Agricultural Pests: Damages, Economics of Control and Compensation in Sri Lanka AgEcon
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.

Willingness to Pay for Conservation of the Asian Elephant in Sri Lanka: A Contingent Valuation Study AgEcon
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...

Livelihoods at Risk: Coping Strategies of War-affected Communities in Sri Lanka JARTS
Korf, Benedikt.
Rural societies in war-affected areas can be described as ’distressed livelihoods’: they experience a dramatic increase in risk and uncertainty. How does this affect land use and agricultural coping strategies of small-scale farm households? This was the key research question of a multi-disciplinary, comparative village study carried out in the war-torn areas of Sri Lanka. The study employed the analytical framework of rural livelihoods promoted by DFID. In addition, theoretical models of risk management were instrumental in illustrating behavioural patterns of households in the war zones. The study shows that changed patterns of mobility are a key response of people to adjust to the risk-prone environment. These strategies place heavy demands on the...

Visitors' reaction to Pinnawala Elephant Orphanage in Sri Lanka: A Survey AgEcon
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...

Ecotourism/Wildlife based Tourism as Contributor to Nature Conservation with Reference to Vanni, Sri Lanka AgEcon
Tisdell, Clement A..
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...

Willingness to pay for different degrees of Abundance of Elephants AgEcon
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...

Open-Cycle Hatcheries, Tourism and Conservation of Sea Turtles: Economic and Ecological Analysis AgEcon
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...

Use and non-use values of wild Asian elephants: A total economic valuation approach AgEcon
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...

ANALYZING NEGOTIATION APPROACHES IN NATURAL RESOURCE MANAGEMENT - A CASE STUDY OF CROP-LIVESTOCK CONFLICTS IN SRI LANKA AgEcon
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...
