“…A single cell model is employed to simulate the response of water resources to changing socioeconomic and environmental conditions. This class of hydrological model is commonly used in the field of water resources economics and there is an extensive body of literature describing their application (see de Frutos Cachorro et al, ; Gisser & Mercado, ; Koundouri, ). The soil column is represented in terms of the total available water , TAW (M/ L 2 ), which describes the maximum amount of water that is available to plants at field capacity:

TAW = ((), θ_{FC} - θ_{WP}) Z_{r},

where θ FC and θ WP (M/L 3 ) are, respectively, field capacity and wilting point and Z r ( L ) is the maximum root depth in meters.…”

Understanding water user behavior and its potential outcomes is important for the development of suitable water resource management options. Computational models are commonly used to assist water resource management decision making; however, while natural processes are increasingly well modeled, the inclusion of human behavior has lagged behind. Improved representation of irrigation water user behavior within models can provide more accurate and relevant information for irrigation management in the agricultural sector. This paper outlines a model that conceptualizes and proceduralizes observed farmer irrigation practices, highlighting impacts and interactions between the environment and behavior. It is developed using a bottom‐up approach, informed through field experience and farmer interaction in the state of Uttar Pradesh, northern India. Observed processes and dynamics were translated into parsimonious algorithms, which represent field conditions and provide a tool for policy analysis and water management. The modeling framework is applied to four districts in Uttar Pradesh and used to evaluate the potential impact of changes in climate and irrigation behavior on water resources and farmer livelihood. Results suggest changes in water user behavior could have a greater impact on water resources, crop yields, and farmer income than changes in future climate. In addition, increased abstraction may be sustainable but its viability varies across the study region. By simulating the feedbacks and interactions between the behavior of water users, irrigation officials and agricultural practices, this work highlights the importance of directly including water user behavior in policy making and operational tools to achieve water and livelihood security.

“…In most empirical studies related to groundwater policies, recommendations are drawn up based on mathematical optimization models (e.g. de Frutos Cachorro et al, 2014). These models consider farmers as homogeneous 'end-users' rather than heterogeneous actors (Venot et al, 2010), which makes their implications sometimes difficult to implement (Vanclay, 2005).…”

“…In such a type of analysis, farmers' adaptation strategies are determined ex ante through surveys and are used as independent variables in the models. Further, some authors (de Frutos Cachorro et al, 2014) analyse temporary reversible groundwater shortages and their effect on farmers' behaviour, while others (Berahmani et al, 2012;Shah, 2012) analyse the effect of 'permanent' groundwater depletion and the strategies farmers adopt to deal with such shortage. Berahmani et al (2012) analysed different strategies adopted by farmers to cope with the groundwater crisis in the Chaouia region in Morocco.…”

The objective of this paper is to identify farmers' strategies to adapt to groundwater shortage in vulnerable arid areas of south Tunisia. In the selected area, the potential of rainfed agriculture is very limited and groundwater is the only source of irrigation. With intensive overuse of groundwater signs of groundwater table depletion are starting to appear and farmers are becoming more concerned about water shortage. Based on a survey among farmers, we proceeded with a ‘principal component factors’ analysis followed by a ‘hierarchical clustering’ using Ward's method, in order to investigate different farmers' adaptation behaviour when faced with groundwater shortage. A set of relevant variables were used for this purpose. The cluster analysis generates three groups of farmers based on their irrigation practices, types of irrigation investment, and other related structural variables. A first group is formed by large farmers who combine both expansive strategies, by investing in enhancing groundwater appropriation, and accommodating strategies, by enhancing on‐farm management of the available resource. The second type of farmers are small and mainly focus on expansive strategies, while the third group is also composed of small farmers demonstrating purely contractive strategies, referring to reduced scale of farm operation.

“…Most studies tackling the groundwater problem have applied modelling in order to target the 'Optimal management of groundwater resource' (Cummings 1971;Provencher and Burt 1993;Moreaux and Reynaud 2004;Tsur and Zemel 2004;de Frutos Cachorro et al 2014). A multidisciplinary approach has been advocated and there has been a long process of theory development.…”

This research estimates the economic losses at the farm level caused by groundwater over-exploitation and by seawater intrusion. The problem of coastal groundwater salinity was tackled by considering its hydrological, agronomic and economic aspects. Economic analysis for competitive use vs. regulated management regimes was carried out, considering constant and adaptive watering techniques. We concentrate on the farmers' perspective of water as an input in agriculture, and assess discounted net present value over a period of 30 years. The ultimate goal of this research is to raise the awareness of farmers and policy makers by demonstrating the economic impacts (from the farmer's point of view) of over-exploitation. Our findings for Apulia Region (Southern Italy) indicate that the slowness of the longterm effect of salinity and the ability of farmers to adapt irrigation profiles suggest broadening the perspective of policy intervention. For an effective management of this common resource, policy makers should follow a more comprehensive approach based on economic analysis.
