Evaluating shifts in rainfall patterns using multi-test change point detection across several rainfall stations in semi-arid climate [PDF]

Journal of Water and Land Development
The rainfall records from twelve stations in Algeria were examined to assess the consistency of the time series and to identify any potential breaks or inhomogeneities. Instead of relying on a single method, four different statistical tests were applied:

The importance of climate scenarios in setting the productivity indexes in the Pampa Arenosa sub-region of the province of Buenos Aires, Argentina

Revista Ambiente & Água, 2019
Starting in the 1970's, the Pampa Arenosa sub-region experienced an increasing water regime that generated an increased area for dryland farming. With increasing agricultural activity, examining the land is an essential strategic tool for its planning ...

Caractérisation de la variabilité temporelle récente des précipitations annuelles au Sénégal (Afrique de l'Ouest)

Physio-Géo, 2014
The wet years of the 1990s have reduced the extent of the area affected by drought. But studies have shown that the rainfall deficit persisted in the Sahelian regions until the end of the 1990s. P. OZER et al., in 2003, thought that the continuity of the

Smart Sensor‐Integrated Lysimeter System for Affordable on‐Farm Crop Water Monitoring and Irrigation Management

Irrigation and Drainage, EarlyView.
ABSTRACT Accurate monitoring of crop water use is critical for precision irrigation, yet conventional lysimeter systems remain too costly and complex for widespread adoption. This study presents the development and field validation of a low‐cost, information and communication technology (ICT)‐enabled weighing lysimeter system that integrates load cells,

Influence des changements d’utilisation des terres sur les débits du bassin versant du Massili à Gonsé (Burkina Faso)

VertigO, 2023
This study aims to determine the contribution of land use changes on runoff in the Massili basin in Gonsé. The study methodology is based on the analysis of the temporal variability of rainfall (1975-2019) and discharge (1975-2019) and the diachronic ...

Drivers and Challenges of Micro‐Irrigation Adoption and Intensity in India: A Study of Four States

Irrigation and Drainage, EarlyView.
ABSTRACT India's food security relies substantially on groundwater, but inefficient irrigation is seriously depleting this resource. Micro‐irrigation (MI) improves irrigation application efficiency and productivity, yet adoption remains low. This study examines MI adoption across four major Indian states—Uttar Pradesh, Maharashtra, Madhya Pradesh and ...

Degradation of Seasonally Frozen Ground in the Three–River Source Region and Its Correlation Impact Within Precipitation–Runoff Process

International Journal of Climatology, EarlyView.
This study reveals how climate change alters the water cycle in the Three Rivers Source region by degrading its important ‘solid groundwater’ (seasonally frozen ground). We found that runoff response varies by watershed and the role of permafrost decreases sharply, making water supply more dependent on rainfall and becoming increasingly vulnerable ...
