Improved Cerrado Wetland Mapping Through Seasonal Moisture Metrics, Terrain Information and Semantic Segmentation

Remote Sensing in Ecology and Conservation, EarlyView.
Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...

Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

Sustainable Development, EarlyView.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.

Media‐Dependent Growth, Stress Responses, and Metal Accumulation Patterns in Azolla imbricata (Roxb.) Nakai Exposed to As, Cd, Cu, Pb, and Zn: Individual and Combination Effects (Synergistic, Antagonistic, and Additive)

Environmental Toxicology, EarlyView.
ABSTRACT In this study, we examined metal accumulation and biochemical responses of Azolla imbricata (Roxb.) Nakai exposed to water medium (WM) and nutrient medium (NM) under single and combined (co‐exposure) treatments with five metals (As, Cd, Cu, Pb, and Zn) at 10% environmentally relevant concentrations.

Root and leaf litter diversity below‐ground shape soil carbon stabilization and priming through altered decomposition dynamics

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Root and leaf turnover is a major contributor to soil organic carbon (SOC) dynamics and storage. However, while roots of multiple species occur in soils, and leaves are often incorporated to soil by bioturbation processes, it remains unknown how litter mixing in soils ...

The Consequences of Soil Organic Carbon for Crop Yield, Farm Productivity and Profit

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Crop choices affect soil organic carbon (SOC) stocks, allowing farmers to manipulate the amount of carbon sequestered in the soil over time. This paper examines the private and public benefits of crop rotations that sequester additional carbon across the province of Saskatchewan, Canada using a novel field‐level dataset from the Saskatchewan ...

Solar irrigation in sub-Saharan Africa: economic feasibility and development potential

Environmental Research Letters, 2023
Irrespective of water resource abundance, agriculture in sub-Saharan Africa (SSA) is predominantly rainfed. Along with fertilization, irrigation could support smallholder farmers with stabilizing crop yields, increasing incomes, and achieving food ...

Repurposing Agricultural Budgets With Multiple Objectives and Fiscal Constraints: A Multicriteria Decision‐Making Policy Tool Applied to Sub‐Saharan African Countries

Journal of Agricultural Economics, EarlyView.
ABSTRACT Repurposing agricultural public resources toward higher‐return incentives and investments can help transform agri‐food systems. This is important for low‐income countries, especially in sub‐Saharan Africa, where limited budgets restrict options for boosting agricultural spending.

A new pump selection method for large-power PV irrigation systems at a variable frequency

, 2018
This paper presents a new method for selecting a pump for large-power PV irrigation systems working at a variable frequency. This can have a significant impact since the traditional way of selecting the pump is based on maximizing the efficiency of pump ...
