Quantifying and modelling the effect of external and internal vegetation water dynamics on radar data

Agriculture plays a critical role in the economy and environment worldwide, and the provision of real-time, reliable information on large-scale agricultural activity is essential for precision agriculture and global economic prosperity. In this context, remote sensing, especially through Synthetic Aperture Radar (SAR), can play an important role...

Assessing the Impact of Agriculture on Water Quality in the Brantas Catchment

In this study, the relationship between water quality and agriculture in the upstream region of the Brantas catchment has been investigated, with a focus on Electric Conductivity (EC), Dissolved Oxygen (DO), pH, nitrate, Biological Oxygen Demand (BOD), phosphate and ammonia concentrations. The EC concentrations ranged from 120 to 570 μS/cm, the...

Revive the Sprengenbeek landscape: Integration of a heritage water system into the renewed circular agricultural landscape at Vaassen, Veluwe

A Sprengenbeek is a stream that has been dug or deepened to tape groundwater from the hill. Most streams were built to drive watermills in order to generate energy, but they were also built to irrigate and supply water to moats, canals, or other waterworks.<br/><br/>The efficiency of the water mills was overruled by modern energy supplies....

Investigation of Well Clogging during Managed Aquifer Recharge of Tile Drainage Water: An ASTR Pilot Study

This study addresses the critical aspects of injection well clogging as part of an Aquifer Storage, Transfer and Recovery (ASTR) pilot infiltrating tile drainage water (TDW) from agricultural field into an anoxic brackish sandy aquifer for later re-use as irrigation water for flower bulbs. Two ASTR injection periods suffering from clogging were...

Reactive transport modelling of push-pull tests: A versatile approach to quantify aquifer reactivity

Push-pull tests (PPTs) were evaluated with 1-D radially axisymmetric multi-component geochemical reactive transport modelling (RTM) to assess aquifer reactivity controlling groundwater quality. Nutrient fate and redox processes were investigated in an Aquifer Storage and Recovery (ASR) system, in which oxic tile drainage water (TDW; nitrate ...

Spatially explicit WEF modelling in transboundary river basins: A new methodology to study the value of cooperation in regional water management

Water, energy and food resources are fundamental for human survival and are critical for supporting economic development. However, ensuring adequate supply is a major concern for the entire world, specifically in some countries and regions. Under the pressure of population growth, economic development, international trade, urbanization,...

A simplified water accounting procedure to assess climate change impact on water resources for agriculture across different European river basins

European agriculture and water policies require accurate information on climate change impacts on available water resources. Water accounting, that is a standardized documentation of data on water resources, is a useful tool to provide this information. Pan-European data on climate impacts do not recognize local anthropogenic interventions in...

Vegetation Optical Depth: its potential as an agricultural drought indicator: A case study on pepper fields in Indonesia

Droughts are a serious threat to the planet. Especially in agriculture, the consequences are devastating leading to reduced yields or crop failure with further implications for economics, politics and society. Being able to monitor and predict agricultural droughts is an important step to reduce agricultural vulnerability and secure livelihoods....

Efficient Water Use in Agriculture: Leading perceptions of key actors in research, policy and practice evaluated at field scale in Tadla basin Morocco and Lower Limpopo basin Mozambique

Expected increase of world wide food demand requires improvement of efficient water use in agriculture in arid and semi-arid regions. The Food and Agriculture Organization (FAO) of the United Nations, the Directorate-General for International Cooperation (DGIS) of the Netherlands and many more key actors at the level of policy, research and...

Exploring water scarcity and drought in Sicilian agriculture: Actors’ performance of European policy instruments

Water scarcity and drought (WS-D) are growing concerns throughout Europe and especially in Southern Regions. This study focuses on agriculture on Sicily, Italy. It explores the way(s) European policies to tackle WS-D are actively performed by the actors in the Sicilian water and agricultural sectors, in order to uncover potential disparities...

Between arguments, interests and expertise: the institutional development of the Dutch water boards, 1953-present

The Dutch water boards perform essential tasks for the Netherlands and generally effectively, yet they have often been called old-fashioned, ineffective and expensive. This paper describes and analyses the discussions on the water boards since 1953 in order to increase insight in the factors that influence institutional change in water...
