Land Cover Change and Hydroclimatic Deviation: A Detailed Examination within the Budyko Framework

Predicting streamflow in a changing climate poses significant challenges for traditional hydrological models. Static parameter sets result from model calibrations over historical data that increasingly encounter the non-stationary impacts on the hydrological system. Endeavouring toward non-stationary model parameters by incorporating time...

Water Level Monitoring in the Karnali River, Nepal: Evaluating Satellite SAR Altimetry Techniques through Field Observations

Rivers play a crucial role in shaping landscapes and supporting ecosystems. This is demonstrated by the tiger habitats in and around Bardia National Park in West-Nepal, which rely on the Karnali River. This study contributes to a larger effort aimed at sustainably managing these tiger habitats. Monitoring the rivers in this remote area is...

Eutrophication prediction in the Dutch coastal waters using remote sensing data and machine learning

Eutrophication processes in coastal waters are becoming more prominent as a result of high nutrient discharges from intensive agriculture and increased urban waste. These processes can be devastating for local ecosystems and lead to dissolved oxygen depletion, which applies considerable stress on aquatic organisms. For ecosystems to preserve...

Do the newly developed models of bare soil surface reflectance and thermal infrared image analysis improve the spatial estimation of soil water properties in the Noordoostpolder region, The Netherlands?

Methodology <br/>Agriculture is an important sector to provide in our needs. Since 2000, the arable land per farmer increased with 66%. To help farmers managing their increasing amount of arable land, it is important to develop new techniques in example based on remote sensing data. One of the key parameters for agricultural management is the...

The application of the FAO WaPOR data portal to monitor efficient water use in agriculture: A case study on the Eastern Nile River Basin

Water scarcity has been a growing problem for many places around the world as water usage has been increasing with double the rate of population growth in the twentieth century. As agriculture accounts for 70 percent of global freshwater withdrawals, fresh water availability will thus face even greater stress (World Bank, 2013). Sustainable...

Bridging the gap between technology and policy: An assessment on how to report progress in efficient water use in agriculture by means of remote sensing data

Water use has increased with double the rate of population growth in the twentieth century. Combined with changing diets due to increased global economic wealth, almost 50 per cent more food needs to be produced to meet demand, implying that fresh water availability will face even greater stress. At the same time, climate change is predicted to...

Monitoring land restoration projects of Justdiggit in Kenya, using downscaled passive microwave remote sensing products of VanderSat

The growing world population and climate change have resulted in increasing stress on the Earth’s ecosystems. Especially the overexploitation of agricultural land, overgrazing and extreme droughts have resulted in land degradation, often called desertification. This leads to the disappearing of natural vegetation, the loss of soil quality, lower...

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....

Mapping of farmer-led irrigated agriculture with remote sensing: A case study in Central Mozambique

In Manica Province in Central Mozambique, agricultural activities consist for a significant part of farmer-led irrigated agriculture. These farmers construct and maintain their own irrigation systems with local inputs and have a commercial intent. Organization is often individual and farmers receive zero to minimal external support from donors,...

Remote sensing of North Sea water quality: A comparison between Sentinel-3 OLCI and in-situ measurements

Chlorophyll (Chl) and Total Suspended Matter (TSM) are both important water quality parameters since they influence the amount of oxygen &amp; amount of light penetrating the water. Oxygen and light are vital in marine ecosystems. The Dutch governmental organisation, Rijkswaterstaat (RWS), has been monitoring the water quality of the Dutch part...

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...

Estimating the Groundwater Recharge of the Chindwin and Irrawaddy Basin in Myanmar Using Remote Sensing Based Water Accounting (WA+)

Sustainable land and water management in Myanmar are desired since the country is rapidly changing. An analysis of the discharge data and an estimation on the groundwater recharge are desired to obtain this. In this paper, the discharge data of seven gauge stations in the Irrawaddy river are analyzed. Also, a method is described to estimate the...

An Assessment of the Monsoon Water Situation in the Kathmandu Valley: Data collection and analysis of flow, water quality, land use and demand

Kathmandu, the capital of Nepal, is under increasing water stress. A rising water demand in the Kathmandu Valley is initiated by urbanisation with a rate of 4.7 % per year and amplified by a growing trend of per capita water consumption. At the same time, water availability seems to deteriorate. However, the severity of the problem is hardly...

Comparison and Validation of Several Open Access Remotely Sensed Rainfall Products for the Nile Basin

Researches about the water cycle are done very often and are very effective to improve the efficiency of the water usage for a basin. Especially in water scarce areas, this type of research are wanted. Water scarcity occurs when water supply cannot meet the water demand. More than half of the world will experience physical or economic water...

Assessing the Accuracy of Water Temperature Determination and Monitoring of Inland Surface Waters Using Landsat 7 ETM+ Thermal Infrared Images

This research evaluates the potential of thermal infrared (TIR) remote sensing to determine and continuously monitor the horizontal water temperature distribution of inland surface water bodies. Usually, monitoring temporal and spatial variability of surface water temperature takes place by measurement networks of in-situ gauges, but these...
