A Framework for Clarifying “Participation” in Participatory Research to Prevent its Rejection for the Wrong Reasons Ecology and Society
Barreteau, Olivier; Cemagref UMR G-EAU; olivier.barreteau@cemagref.fr; Bots, Pieter W. G.; Delft University of Technology; p.w.g.bots@tudelft.nl; Daniell, Katherine A; Australian National University; katherine.daniell@gmail.com.
Participatory research relies on stakeholder inputs to obtain its acclaimed benefits of improved social relevance, validity, and actionability of research outcomes. We focus here on participatory research in the context of natural resource management. Participants’ acceptance of participatory research processes is key to their implementation. Our first assumption is that this positive view and acceptance of participation in research processes is a public good for the whole participatory research community. We also assume that the diversity of participatory forms of research is rarely considered by potential participants when they make their decisions about whether or not to participate in a proposed process. We specifically address how to avoid...

A gender performance indicator for irrigation: Concepts, tools and applications AgEcon
van Koppen, Barbara.
Although gender issues are today a priority on the agendas of irrigation policy makers, interventionists, farm leaders and researchers, there is still a considerable gap between positive intentions and concrete action. An important but hitherto ignored reason for this is the lack of adequate generic concepts and tools that are policy-relevant and can accommodate the vast variation in irrigation contexts worldwide. The Gender Performance Indicator for Irrigation (GPII) aims to fill this gap. In any particular scheme, this tool diagnoses the gendered organization of farming and gender-based inclusion or exclusion in irrigation institutions. It informs irrigation agencies what they themselves can do for effective change-if necessary. The tool also identifies...

Accounting for water use and productivity AgEcon
Molden, David J..
This paper presents a conceptual framework for water accounting and provides generic terminologies and procedures to describe the status of water resource use and consequences of water resources related actions. The framework applies to water resource use at three levels of analysis: a use level such as an irrigated field or household, a service level such as an irrigation or water supply system, and a water basin level that may include several uses. Water accounting terminology and performance indicators are developed and presented with examples at all the three levels. Concepts and terminologies presented are developed to be supportive in a number of activities including: identification of opportunities for water savings and increasing water...

Adaptive Water Governance: Assessing the Institutional Prescriptions of Adaptive (Co-)Management from a Governance Perspective and Defining a Research Agenda Ecology and Society
Huitema, Dave; Vrije Universiteit Amsterdam - Institute for Environmental Studies; dave.huitema@ivm.vu.nl; Mostert, Erik; Delft University of Technology - Centre for River Basin Administration; E.Mostert@TUDelft.NL; Egas, Wouter; Vrije Universiteit Amsterdam - Institute for Environmental Studies; wouter.egas@ivm.vu.nl; Yalcin, Resul; University of Bonn - Center for Development Research; ryalcin@uni-bonn.de.
This article assesses the institutional prescriptions of adaptive (co-)management based on a literature review of the (water) governance literature. The adaptive (co-)management literature contains four institutional prescriptions: collaboration in a polycentric governance system, public participation, an experimental approach to resource management, and management at the bioregional scale. These prescriptions largely resonate with the theoretical and empirical insights embedded in the (water) governance literature. However, this literature also predicts various problems. In particular, attention is called to the complexities associated with participation and collaboration, the difficulty of experimenting in a real-world setting, and the politicized nature...

Aluminum-based water treatment residual use in a constructed wetland for capturing urban runoff phosphorus: Column study NWISRL
Ippolito, J.A..
Aluminum-based water treatment residuals (Al-WTR) have a strong affinity to sorb phosphorus. In a proof-of-concept greenhouse column study, Al-WTR was surface-applied at 0, 62, 124, and 248 Mg/ha to 15 cm of soil on top of 46 cm of sand; Al-WTR rates were estimated to capture 0, 10, 20, and 40 years of phosphorus from an urban watershed entering an engineered wetland in Boise, Idaho, USA. Creeping red fescue (Festuca rubra) was established in all columns; one set of columns received no Al-WTR or plants. After plant establishment, once per week over a 12-week period, ~1.0 pore volumes of ~0.20 mg phosphorus/L was added to each column. Infiltration rates were measured, leachate was collected and analyzed for soluble phosphorus, and fescue yield,...

An Approach to Sustainable Water Management Using Natural Resource Accounts: the Use of Water, the Economic Value of Water, and Implications for Policy OceanDocs
Lange, G.M..
A Natural Resource Accounting project is currently underway to document the status of the nation’s resources and their current economic use. Accounts for water constitute a major component of the Natural Resource Accounts (NRA) since water is the limiting resource for economic development in Namibia, as it is for much of Southern Africa. The NRA include both stock and use accounts for water, as well as related environmental statistics. In order to design development strategies that are sustainable over the long run, it is essential to know the full value of this scarce resource. This is especially important for a resource like water which is used throughout the economy and must be managed to achieve sometimes conflicting economic, social, and political...

Automatically controlled deficit irrigation of lettuce in “organic potponics” Scientia Agricola
Valença,David da Cunha; Carvalho,Daniel Fonseca de; Reinert,Fernanda; Azevedo,Ricardo Antunes; Pinho,Camila Ferreira de; Medici,Leonardo Oliveira.
ABSTRACT: Concerns with water crisis involve all sectors of society and irrigated agriculture remains the main water consumer. This study evaluated an agricultural production system for lettuce cultivation in greenhouse, “organic potponics”, to economize water and manure use, using a Simplified Irrigation Controller (SIC), based on soil matric potential monitoring. Five irrigation volumes were evaluated in pots with 4.8 L, fertilized with 200 g of vermicompost. One of the volumes was controlled with the SIC. The other volumes represented 130, 80, 60 and 33 % of that controlled by the SIC and all treatments received water at the same time. Shoot fresh weight, head diameter and stomatal conductance (gs) increased linearly with irrigation volumes. For shoot...

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.

Calibrating and validating AquaCrop model for maize crop in Northern zone of Nigeria CIGR Journal
Ezekiel, Oiganji; Igbadun, H. E.; Mudiare, O.J.; Oyebode, M.A..
Farmers in the northern Guinea Savannah ecological zone of Nigeria have been experiencing declining crop yield due to erratic water supply. In recent times, research on better water management and interaction between effects of climate, soil and field management on crop production is fast gaining grounds with the use of models. Models can be used to predict the impact of long-term climate variability, thus providing an opportunity of better techniques compared with the traditional multi-location trials. This study presents the calibration and validation of AquaCrop model for drip irrigated maize (Zea mays). Calibration was done using data of 2013, while validation across seasons was done with data of 2014. The modelling efficiency of grain yield, biomass...

Changes in chemical attributes of a Fluvent cultivated with castor bean and irrigated with wastewater AGRIAMBI
Barreto,Aurelir N.; Nascimento,Joab J. V. R. do; Medeiros,Everaldo P. de; Nóbrega,Janiny A. da; Bezerra,Jose R. C..
Agricultural use of wastewater is an alternative to increase water availability, especially in semiarid regions. However, it may cause undesirable chemical changes in the soil. The aim of this study was to evaluate the influence of wastewater irrigation and castor bean (Ricinus communis L.) cultivation on the chemical attributes of a Fluvic Neosol. The experimental design was in a randomized block, in split-plot scheme, where the main plots were represented by the treatments of irrigation water and castor bean cultivation, and the subplots were the soil layers, with three replications. The treatments were T1 - wastewater irrigation + castor bean cultivation ; T2 - mixture of supply water and wastewater (1:1 ratio) + castor bean cultivation; T3 - supply...
