World Water Demand and Supply, 1990 to 2025: Scenarios and Issues
(1998) Seckler, David; Amarasinghe, Upali A.; Molden, David; de Silva, Radhika; Barker, Randolph
"Presents two alternative scenarios of water demand and supply for 118 countries over the 1990 to 2025 period and develops indicators of water scarcity for each country and for the world as a whole. This study is the first step in IWMI's long-term research goal: to determine the extent and depth of water scarcity, its consequences for individual countries and what can be done about it."
Investing in Water for Food, Ecosystems and Livelihoods
(2004) Molden, David; de Fraiture, Charlotte
"Sustainably meeting the food and livelihood needs of a growing population will require some very difficult choices about how water is developed and managed in the next 25 years. More food will be necessary, and more food translates into more water for agriculture. More water for agriculture will in many cases mean less for the environment. So how do you manage water for food and the environment? And how do you do so in a way that also reduces poverty? In the following pages we review several policy and water investment options—along with their livelihood and environmental implications. This paper presents issues being addressed by the Comprehensive Assessment of Water Management in Agriculture, an international research program that brings together scientists, development professionals and stakeholders from around the world. This is the first time science has been focused at this level and intensity on answering questions related to water, agriculture, poverty and environmental conservation. The Assessment is at the mid-way mark and won’t be complete until 2006, but already we have evidence to suggest which approaches are the most promising. Our intention in sharing these preliminary findings is to raise awareness that water in agriculture is a pressing issue, that business as usual is not an option, and that there are potential solutions, but they are not necessarily the ones that have received the most attention."
Water for Food, Water for Life: Influencing What Happens Next
(2007) Rodriguez, Dawn; Molden, David
"Will there be enough water to grow enough food for a growing population over the next 50 years or will we run out of water? It is possible to produce the food, but it is probable that today’s food production and environmental trends will lead to crises in many parts of the world."
Water and the Millennium Development Goals: Meeting the Needs of People and Ecosystems
(2003) Molden, David; Falkenmark, Malin
"When viewed in terms of water, the Millennium Development Goals (MDGs) targeting poverty and hunger seem to be in direct conflict with the goal on environmental sustainability. It is becoming increasingly clear that ensuring people access to water for growing food and earning a living will be necessary to end extreme poverty and hunger in rural areas."
Remote Sensing and Hydrologic Models for Performance Assessment in Sirsa Irrigation Circle, India
(1999) Bastiaanssen, W.G.M.; Molden, David; Thiruvengadachari, S.; Smit, A. A. M. F. R.; Mutuwatte, Lal; Jayasinghe, Gayathri
"Describes the results of an irrigation performance evaluation using remote sensing techniques, GIS procedures, and hydrologic modeling at a regional scale. Demonstrates how advanced information technologies support the analysis of irrigation performance by facilitating an in-depth study of a large irrigated area."
Integrated Land and Water Management for Food and Environmental Security
(2003) Penning de Vries, F.W.T.; Acquay, H.; Molden, David; Scherr, Sara J.; Valentin, C.; Cofie, Olufunke O.
"This document focuses on the impact of degradation of land and water on food and environmental security. It aims to provide a basis for priority policy and research actions that will counteract the progression of degradation and will reduce its impact on household food security and the loss of other ecosystem services."
Assessment of Conjunctive Use in Maharashtra Minor Irrigation Systems
(1991) Sawant, M.M.; Barrett, R.E.; Molden, David; Sheng, T.S.
"The objective of this paper is to provide a brief assessment of the status of well irrigation and conjunctive use in Maharashtra. In light of the assessment, we will note areas where assistance could be used to improve the status of conjunctive use. The focus of the paper is on minor irrigation systems. Minor irrigation systems serve less than 2,000 ha and usually consist of a small tank for storing water and a canal distribution system. The development of surface irrigation has led to a rise in wells due to canal seepage in the command areas."
Integrated Development and Management of Water Resources for Productive and Equitable Use in the Indrawati River Basin, Nepal
(2002) Bhattarai, Madhusudan; Pant, Dhruba; Mishra, V. S.; Devkota, Hari; Pun, Shuku; Kayastha, R. N.; Molden, David
"This paper on the Melamchi water transfer project which is being carried out in the Indrawati river basin,3 is a summary and synthesis of four detailed case studies conducted earlier, in relation to the project. The case studies were conducted in Nepal by the IWMI and Water and Energy Commission Secretariat (WECS)/Nepal team, funded by the Ford Foundation/India."
Hydronomic Zones for Developing Basin Water Conservation Strategies
(2001) Molden, David; Sakthivadivel, R.; Keller, Jack
"In this report, the concept and procedures of hydronomic (hydro water + nomus management) zones are introduced. A set of six hydronomic zones are developed and defined based on key differences between reaches or areas of river basins. These are the: Water Source Zone, Natural Recapture Zone, Regulated Recapture Zone, Stagnation Zone, Final Use Zone, and Environmentally Sensitive Zone. The zones are defined based on similar hydrological, geological and topographical conditions and the fate of water outflow from the zone. In addition, two conditions are defined which influence how water is managed: whether or not there is appreciable salinity or pollution loading; and whether or not groundwater that can be used for utilization or storage is present. Generic strategies for irrigation for four water management areas, the Natural Recapture, Regulated Recapture, Final Use, and Stagnation Zones, are presented. The Water Source Zone and Environmentally Sensitive Zone are discussed in terms of their overall significance in basin water use and management. "Hydronomic zones allow us to define, characterize, and develop management strategies for areas with similar characteristics. The concept of zoning is demonstrated in four agricultural areas representing a wide variety of situations: the Kirindi Oya basin in Sri Lanka, Egypts Nile basin, the Bhakra command area in Haryana, India and the Gediz basin in Turkey. We were readily able to apply the zones within each basin and suggest water management strategies for each zone. Hydronomic zones hold potential as a tool to help us better understand complex water interactions within river basins, to isolate similar areas within basins and to help us develop sets of water management strategies better tailored to different conditions within basins."
Indicators for Comparing Performance of Irrigated Agricultural Systems
(1998) Molden, David; Sakthivadivel, R.; Perry, C.J.; de Fraiture, Charlotte
"A set of comparative performance indicators is defined, which relates outputs from irrigated agriculture to the major inputs of water, land, and finance. Nine indicators are presented with the objective of providing a means of comparing performance across irrigation systems. These indicators require a limited amount of data that are generally available and readily analyzed. Results of application of the indicators at 18 irrigation systems are presented and large differences in performance among systems are shown. In spite of uncertainties in estimation of indicators, the large differences discerned by the indicators justify the approach taken."
