Mulching Increases Water Use Efficiency, Production and Profitability in Forage Cactus–Maize Intercropping Systems

Irrigation and Drainage, EarlyView.
ABSTRACT This study evaluated the growth, forage production, soil water balance, water indices, biological efficiency and competitive capacity of forage cactus and maize in monoculture and intercropping, with or without mulch. The experiment was conducted in Serra Talhada, Pernambuco, Brazil, using the cactus clone ‘Orelha de Elefante Mexicana’ (OEM ...

MANAGEMENT DISCRIMINANT PROPERTIES IN SEMIARID SOILS

Soil Science, 1998
The physical properties of coarse - textured soils in semiarid regions often deteriorate with use. We hypostatized that the changes in the physical properties of the soil were related to the cropping sistem employed. 5urface sampled of 52 Entic Haplustolls under three diferents uses (24 under continuous cultivation), 18 under rotation wuth grass Ieys ...

Quantifying Farm Household Resilience and the Implications of Livelihood Heterogeneity in the Semi-Arid Tropics of India

Agriculture, 2022
The vast majority of farmers in the drylands are resource-poor smallholders, whose livelihoods depend heavily on their farming systems. Therefore, increasing the resilience of these smallholders is vital for their prosperity.

Evapotranspiration Profiles and Trends in Seasonally Dry and Seasonally Humid Tropical Forests

International Journal of Climatology, EarlyView.
Moisture availability and vegetation are decisive factors in ET variations, which are greater in the Atlantic Forest. Precipitation contributes positively to ET variations (r = 0.20–0.67). Significant trends (p < 0.05) in ET were identified, with opposing patterns.

Heat and Cold Waves in Brazil: An ERA5‐Based Analysis of Trends and Seasonality (1980–2024)

International Journal of Climatology, EarlyView.
This study uses ERA5 reanalysis data to assess changes in extreme heat and cold events across Brazil from 1980 to 2024. Results reveal a sharp increase in heatwave frequency and a general decline in coldwave occurrences, though regional variations are substantial.
