A framework for efficient wastewater treatment and recycling systems AgEcon
Mekala, Gayathri Devi; Davidson, Brian; Samad, Madar; Boland, Anne-Maree.
Use of un-treated/partially treated wastewater for irrigation in the dry countries of Asia and Africa and recycling of treated wastewater in the water scarce developed countries has become a common practice due to various reasons. While the lack of wastewater treatment to appropriate levels before use is a major problem in developing countries, the high cost of wastewater recycling is the major problem in developed countries. The current paper is part of a doctoral research and presents the conceptual framework for the research and the methodology that can be used to tackle the problems associated with wastewater recycling.

Agro-well and pump diffusion in the dry zone of Sri Lanka: Past trends, present status and future prospects AgEcon
Kikuchi, Masao; Weligamage, Parakrama; Barker, Randolph; Samad, Madar; Kono, Hiroichi; Somaratne, H.M..
The use of shallow wells, equipped with small pumps, to lift groundwater has spread rapidly in many agricultural regions of tropical monsoonal Asia. In Sri Lanka, the rapid and pervasive invasion of agro-wells and pumps drew the attention of policymakers and researchers, but many questions were left unanswered due to lack of research in the area. This study aims to fill this gap in knowledge, based on observations and data obtained in field surveys conducted in major and minor irrigation schemes in the dry zone of Sri Lanka. This report gives the key findings of this study into the pattern, extent and causes of the spread and use of agro-wells and pumps in traditional villages and irrigated settlement schemes. It investigates farmer investments in...

Assessing the economic impact of redistributing water within a catchment: A case study of the Musi Catchment in the Krishna Basin in India AgEcon
Davidson, Brian; Hellegers, Petra J.G.J.; Samad, Madar.
The aim in this paper was to present the details of an economic modeling exercise conducted on the Musi Catchment of the Krishna Basin. The model has the unique characteristic of being able to value the water used on individual crops and in different regions. Thus, the individual values of water used to produce different crops, grown over two different seasons and over five very different regions within a catchment, were determined. This is a significant improvement over previous attempts, where a single value of water in a catchment was derived regardless of what it is used for, when it was used and where it used in the catchment. In addition to the agricultural valuation process, some account was made for the other uses of water and how they should be...

Assessing the outcomes of IWMI’s research and interventions on irrigation management transfer AgEcon
Giordano, Meredith A.; Samad, Madar; Namara, Regassa E..
The purpose of this paper is to summarize IIMI/IWMI's past research and interventions related to irrigation management transfer and to document, to the extent possible, the academic, policy, and technical outcomes of these efforts. The application of a range of direct and indirect measurement techniques suggests an overall positive contribution from IWMI to IMT theory and application.

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...

Synthesis of IWMI work in Nepal AgEcon
Pant, Dhruba; Samad, Madar.
The International Water Management Institute (IWMI) has been working in Nepal since 1986 with the objective of undertaking research in water management and to strengthen the research capabilities of concerned government agencies. The research helped to develop appropriate mechanisms for providing support to Farmer-Managed Irrigation Systems (FMIS) and the initiation of participatory irrigation management (PIM). The river basin studies helped policy formulation for integrated planning and management of water resources besides the methodological contribution through the development of appropriate tools for water management studies. It also contributed to enhancing the capabilities of agency officials and local researchers through their involvement in...

Valuing a Clean River: A case study of Musi River, Hyderabad, India AgEcon
Gayathri Devi, Mekala; Samad, Madar; Davidson, Brian; Boland, Anne-Maree.
The current study uses contingent valuation technique to estimate the value of clean water in river Musi in Hyderabad, India. The main source of pollution of the river is untreated domestic and industrial wastewater from the urban area of Hyderabad. Therefore, people’s Willingness To Pay [WTP] for the treatment of their wastewater to different quality levels (Level C, B & A) is estimated using a payment card method. Four variables were considered to influence the willingness to pay - number of years the household lived in Hyderabad; individual perceived importance of controlling water pollution; household income levels and proximity to the river. The results of the logistic regression confirmed that the variables - perceived importance of the...
