Protocolos de riego en uva de mesa según disponibilidad de agua de riego

 Proceedings of the 9th Workshop on Agri-Food Research for young researchers. WiA
[SPA] Las estrategias de Riego Deficitario Controlado (RDC) permiten ahorrar agua sin generar pérdidas en la producción y calidad de las cosechas y así, incrementar la eficiencia en el uso del agua de riego. No obstante, deben ajustarse a la dotación hídrica del agricultor para cada año. Se realizó un estudio en uva de mesa Crimson Seedless durante los

Wetland location and captive breeding influence trans‐Mediterranean movements in the endangered Marbled Duck (Marmaronetta angustirostris)

Ibis, Volume 168, Issue 1, Page 245-258, January 2026.
Waterbirds distributed in semi‐arid and arid regions seem to have adapted their behaviour to the availability and seasonality of wetlands, increasing their mobility range. The Marbled Duck Marmaronetta angustirostris is a threatened waterbird that shows trans‐Mediterranean movements but these are poorly known.

Spatial Assessment of Heavy Metal Contamination in Agricultural Soils of the Lower Chancay–Huaral Valley, Peru

Applied and Environmental Soil Science, Volume 2026, Issue 1, 2026.
Soil contamination by heavy metals (HMs) poses a potential threat to agricultural productivity and food security, particularly in rapidly developing coastal regions. This study evaluates the spatial distribution and contamination levels of cadmium (Cd), copper (Cu), lead (Pb), zinc (Zn), and manganese (Mn) in agricultural soils from the Huaral, Chancay,

Soil Organic Carbon Variability in Tropical Cropping Systems: Interactions With Texture, pH, Macronutrients, and Organic Matter

International Journal of Agronomy, Volume 2026, Issue 1, 2026.
Soil organic carbon (SOC) plays a crucial role in mitigating climate change and enhancing soil fertility. Its storage and dynamics are particularly significant in agricultural ecosystems of the Peruvian Amazon, where the expansion of agriculture and livestock farming may disrupt the regional carbon balance.

Governing the Ungovernable: Mapping the Development of Groundwater Irrigation and Groundwater Policies in India

World Water Policy, Volume 11, Issue 4, Page 1048-1064, November 2025.
ABSTRACT Groundwater governance is complex due to several externalities associated with groundwater being an invisible natural resource tied to the land with millions of extractors and limited means of exclusion. The paper traces the evolution of groundwater irrigation in India and the corresponding change in groundwater laws and policies to address ...
