A Simple Agro-Economic Model for Optimal Farm Nitrogen Application under Yield Uncertainty
(MDPI, 2021)
Farmers in the developed world tend to over-apply fertilizer, and we explore a model for decision-making under uncertainty in yields. This article proposes an agro-economic model for farmer decision-making based on subjective ...
Microeconomics of Deficit Irrigation and Subjective Water Response Function for Intensive Olive Groves
(MDPI, 2016)
Abstract
This research paper analyzes the economics of deficit irrigation based on the use of subjective estimates of the crop yield–water relationship to determine water supply in irrigated olive groves. Interviewed ...
Using Ostrom’s DPs as Fuzzy Sets to Analyse How Water Policies Challenge Community-BasedWater Governance in Colombia
(MDPI, 2017)
Ostrom’s design principles have been broadly used to analyse the governance of common
pool resources. However, they are normally assessed as present or absent. We challenge this
assumption by considering them as fuzzy ...
Building a Composite Indicator to Measure Environmental Sustainability Using Alternative Weighting Methods
(MDPI, 2020)
Environmental sustainability in agriculture can be measured through the construction of composite indicators. However, this is a challenging task because these indexes are heavily dependent on how the individual base ...
An Analysis of Irrigation Organizations in Colombia through the Prism of Collective Action
(MDPI, 2019)
The objective of this article is to deepen the knowledge of collective action in irrigation organizations in Colombia, by identifying the limitations of the members for their organizational work and the variables of context ...
Agricultural Water Allocation Under Cyclical Scarcity: The Role of Priority Water Rights
(MDPI, 2020)
Water is becoming an increasingly scarce resource worldwide, suggesting that water rationing methods should be revised to improve water allocation efficiency, especially during cyclical scarcity events (droughts). The ...
The Drivers-Pressures-State-Impact-Response Model to Structure Cause−Effect Relationships between Agriculture and Aquatic Ecosystems
(MDPI, 2021)
Different segments of society have shown interest in understanding the effects of human activities on ecosystems. To this end, the aim of this article is to analyze the scientific literature on the application of the ...
Hydro-Economic Modelling for Water-Policy Assessment Under Climate Change at a River Basin Scale: A Review
(MDPI, 2020)
Hydro-economic models (HEMs) constitute useful instruments to assess water-resource management and inform water policy. In the last decade, HEMs have achieved significant advances regarding the assessment of the impacts ...
Learning from the Past in the Transition to Open-Pollinated Varieties
(MDPI, 2020)
In Nepal, hybrid seed introduction caused major yield gains in agricultural production, but at high environmental costs. The development of high-yielding open-pollinated varieties has spurred hope for more sustainable ...
Knowledge Transfer on Digital Transformation: An Analysis of the Olive Landscape in Andalusia, Spain
(MDPI, 2022)
The global economy, and agriculture, in particular, faces significant challenges and transformation pressures. A major challenge, and opportunity, is the transformation towards digital agriculture or agriculture 4.0, where ...
