    Imaginaries of place in territorialization processes:Transforming the Oyacachi<i> páramos</i> through nature conservation and water transfers in the Ecuadorian highlands

    How Ecuadorian páramos are perceived has drastically changed over the last five decades. From cold, hostile, and unproductive hinterlands, páramos have changed to become areas for biodiversity conservation and ‘water towers’ that ought to be protected to provide clean and abundant water for cities and irrigation. To understand how these changing perceptions of páramos relate to interventions and their on-the-ground negotiation by local communities, we develop the notion of imaginaries of place and explore its relations to notions of governmentality and territorialization. We show how, based on changing imaginaries of what páramos are, state and non-state interventions have tried to control the Oyacachi páramos in the Northern Ecuadorian Highlands for the specific purpose of nature and water conservation. At the same time, we show that these interventions are highly contested on-the-ground. This leads to confrontations, negotiations, and a re-definition of the imaginaries of place there exist. Our analysis expounds the relevance of understanding imaginaries of place and its close relations to interventions and their negotiation

    Water, Food, and Irrigation

    Irrigated agriculture plays a central role in global food production as it provides resilience to rainfall variability, increased productivity and production security. However, it has also gone hand in hand with serious socio-environmental challenges. Large-scale irrigated agricultural production, which depends on both surface and groundwater resources, has encountered several technical and managerial challenges. It has led to widespread environmental deterioration through drying and polluting rivers, lakes, wetlands, and aquifers. At the same time, irrigated agricultural production has been increasingly commodified, specialized and globalized through large commercial farming enterprises, contract farming and international agro-export chains. This has led to widespread processes of land and water accumulation and related socio-environmental inequities in many regions of the world. In contraposition to this tendency peasant irrigated production plays a key role in producing for local and regional fresh food markets. In this context, we explore a few innovative and promising grassroots initiatives that spring from peasant agriculture. These are agro-ecology, farmer-led irrigation development and peri-urban agriculture, all initiatives that rest on the creation of local food production and marketing networks. Finally, this book chapter closes by setting out critical questions about policies and the political implications of food consumption patterns

    Satellite‐Based Monitoring of Irrigation Water Use: Assessing Measurement Errors and Their Implications for Agricultural Water Management Policy

    Reliable accounting of agricultural water use is critical for sustainable water management. However, the majority of agricultural water use is not monitored, with limited metering of irrigation despite increasing pressure on both groundwater and surface water resources in many agricultural regions worldwide. Satellite remote sensing has been proposed as a low-cost and scalable solution to fill widespread gaps in monitoring of irrigation water use in both developed and developing countries, bypassing the technical, socioeconomic, and political challenges that to date have constrained in situ metering. In this paper, we show through a systematic meta-analysis that the relative accuracy of different satellite-based irrigation water use monitoring approaches remains poorly understood, with evidence of large uncertainties when water use estimates are validated against in situ irrigation data at both field and regional scales. Subsequently, we demonstrate that water use measurement errors result in large economic welfare losses for farmers and may negatively impact ability of policies to limit acute and nonlinear externalities of irrigation abstraction on both the environment and other water users. Our findings highlight that water resource planners must consider the trade-offs between accuracy and costs associated with different water use accounting approaches. Remote sensing has an important role to play in supporting improved agricultural water accounting—both independently and in combination with in situ monitoring. However, greater transparency and evidence is needed about underlying uncertainties in satellite-based models, along with how these measurement errors affect the performance of associated policies to manage different short- and long-term externalities of irrigation water use

    The social construction and consequences of groundwater modelling: insight from the Mancha Oriental aquifer, Spain

    [EN] Groundwater flow models have been increasingly used to support policy making. A substantial amount of research has been dedicated to improving, validating and calibrating models and including stakeholders in the modelling process. However, little research has been done to analyze how the choices of model makers and steering by policy makers result in models with specific characteristics, which only allow specific modelling outcomes, and how the use of these modelling outcomes leads to specific social, economic and environmental consequences. In this study, we use the social construction of technology framework to explore the development, characteristics and uses of the groundwater model of the Mancha Oriental aquifer in Spain. The specific characteristics and functioning of this model influenced the policy implementation, implying that involving stakeholders in the development and use of models is crucial for improved democratic policy making.This work was carried out as part of the collaboration agreement between the University of Castilla–La Mancha and Wageningen University.
