Selecting ecological indicators to compare maintenance costs related to the compensation of damaged ecosystem services ArchiMer
Vaissiere, Anne-charlotte; Levrel, Harold; Hily, Christian; Le Guyader, Damien.
The aim of this paper is to compare different maintenance costs of ecosystem service arising from a hypothetical case of environmental damage in order to help to understand how the different ecosystem services are considered in decision making processes. Compensatory measures are aimed precisely at maintaining the level of supply of ecosystem services. According to the literature, compensatory measures like restoration are usually applied to specific ecosystem services. We used the Millennium Ecosystem Assessment (MEA) categories of ecosystem service. For each MEA category, several ecological indicators are selected, and the cost of the compensatory measures required to fulfill the goal of no net loss is assessed using the Habitat Equivalency Analysis...

Financing irrigation services: a literature review and selected case studies from Asia AgEcon
Small, Leslie E.; Adriano, Marietta S.; Martin, Edward D.; Bhatia, Ramesh; Shim, Young K.; Pradhan, Prachanda.
This study results from a two years' intensive research into a hitherto unexplored area of irrigation management - the aspect of financing irrigation in some Asian countries. The authors have analyzed the relationship between investment costs, level of irrigation fees, cropping intensity, type of crop, and secondary income. The studies conclude that the quality of irrigation system operations and maintenance is affected not only by the amount of resources made available to operate and maintain systems, but also by the institutional arrangements under which they are provided.
Tipo: Book Palavras-chave: Irrigation management; Irrigation operation; Financing; Resource management; Rehabilitation; User charges; Maintenance costs; Operating costs; Agricultural Finance; Farm Management.

Irrigation sector in Sri Lanka: Recent investment trends and the development path ahead AgEcon
Kikuchi, Masao; Barker, Randolph; Weligamage, Parakrama; Samad, Madar.
Increasing the area under irrigation and the widespread adoption of seed-fertilizer technology were the major factors that contributed to enhanced rice production in Sri Lanka, enabling the country to achieve self-sufficiency in rice. In recent years, there has been a shift in emphasis from expanding the irrigated land base to enhancing the productivity of irrigated land through diversification of agriculture and improvement of rice production, with better water management in irrigation schemes. This report attempts to assess how the irrigation sector in Sri Lanka is adapting itself to these new challenges. It analyzes the future direction of irrigation in Sri Lanka in light of recent trends in public and private investment in this sphere, and the...
