Low-carbon agricultural technologies improve forage and feed production in the Caatinga biome, Brazil: Characteristics, comparison, effects of climate change, resilience, local development, and food security

Scientia Agropecuaria
Adjustments in Brazilian livestock are necessary to minimize greenhouse gas (GHG) emissions, since the largest source of methane comes from ruminants’ enteric fermentation, and of carbon from deforestation.

Trait‐based restoration in African dryland restoration projects: overcoming systemic and scientific barriers for a viable future

Restoration Ecology, EarlyView.
Abstract Introduction African dryland restoration continues to show low success rates despite major pledges, due to persistent water scarcity, ecological complexity, and limited use of trait‐based restoration (TBR). Functional trait‐based approaches, which match species selection to adaptive traits, could strengthen ecosystem recovery under arid ...

Effect of Different Irrigation Programs on Structural Characteristics, Productivity and Water Use Efficiency of Opuntia and Nopalea Forage Cactus Clones

Grasses
The objective of this study was to evaluate the structural characteristics, yield and water use efficiency of forage cactus under daytime and nighttime irrigation in a Brazilian semiarid region. The experiment followed a completely randomized design in a

Glancing at childhoods in the Semiarid

, 2015
Triggering some flashes that glance at the childhood universe, this essay presents discussions – based on a cultural, socio-historical and environmental panorama – from a place/time nowadays called Brazilian Northeastern Semiarid. These discussions aim, through problematizations,  to provoke reflections on the construction of childhoods. Thus, the

Integrating herbicide application and seeding techniques to restore native plant diversity in crested wheatgrass‐dominated rangelands

Restoration Ecology, EarlyView.
Abstract Introduction Restoring native plant diversity in crested wheatgrass (Agropyron cristatum)‐dominated rangelands is a persistent challenge in ecological restoration across western North America. Dense, long‐lived stands of this exotic grass suppress native seedling recruitment, hinder habitat restoration, and reduce ecosystem resilience ...

Mapping Burned Area in the Caatinga Biome: Employing Deep Learning Techniques

Fire
The semi-arid Caatinga biome is particularly susceptible to fire dynamics. Periodic droughts amplify fire risks, while anthropogenic activities such as agriculture, pasture expansion, and land-clearing significantly contribute to the prevalence of fires.

Gypsic soils in the Brazilian Semiarid

Revista Brasileira de Ciência do Solo
ABSTRACT Globally, soils with gypsic horizons cover approximately 1 million km², predominantly in arid climates. The formation of pedogenic gypsum in soils has been a topic of discussion in pedological studies for some time, with gypsification representing the process responsible for secondary gypsum accumulation.

Alternative approaches to dryland reclamation enhance vegetation cover and soil stability at a former uranium mine

Restoration Ecology, EarlyView.
Abstract Introduction Conventional reclamation methods to recover dryland ecosystems after mineral extraction often have low success. Alternative reclamation techniques may help overcome the many challenges to establishing persistent native vegetation and stable soils.

HOW STRONG IS THE RELATIONSHIP BETWEEN RAINFALL VARIABILITY AND CAATINGA PRODUCTIVITY? A CASE STUDY UNDER A CHANGING CLIMATE

Anais da Academia Brasileira de Ciências
Despite the knowledge of the influence of rainfall on vegetation dynamics in semiarid tropical Brazil, few studies address and explore quantitatively the various aspects of this relationship.

Disturbance legacies in arid environments shape recovery of former agricultural land

Restoration Ecology, EarlyView.
Abstract Introduction Increasingly, arid agricultural land is being permanently taken out of irrigated production due to more frequent drought, higher temperatures, and the overconsumption of groundwater, with important ramifications for ecological recovery.
