State infrastructural power in a neopatrimonialist democratization context: Why Tunisian sustainable land management fails

Review of Policy Research, Volume 41, Issue 6, Page 985-1016, November 2024.
Abstract Sustaining agricultural production in arid and semi‐arid regions is of paramount importance to food security, geo‐political independence, and social stability. In this context, it is vital to understand the effectiveness of policies. In this article, we aim to answer the question of what role the state and its policies play for soil protection

Similar climate–growth relationships but divergent drought resilience strategies in coexisting Mediterranean shrubs

Journal of Ecology, Volume 112, Issue 8, Page 1804-1817, August 2024.
These results highlight the importance of drought as a driver of growth in Mediterranean scrublands. Growth resilience strategies differed between species with junipers being less resilient to drought than other coexisting shrubs. Further research should investigate how this difference in post‐drought resilience is related to functional traits ...

Nutrient losses due to water erosion using simulated rainfall in southern Brazil

Dyna, 2018
Erosion is the main form of degradation in the world, consequently of loss of soil, water and nutrients, provoking direct and indirect damages. The objective of this work is to quantify N, P and K losses by water erosion under simulated rainfall ...

Distinct bird communities in forests and fruit farms of Caatinga landscapes

Ibis, Volume 166, Issue 3, Page 1081-1091, July 2024.
Agricultural expansion and intensification drive changes in bird assemblages and contribute to the homogenization of communities. By working across the semi‐arid biome of the Caatinga in northeastern Brazil, this study is the first to compare the bird communities found in intensively managed fruit farms with those in remnant Caatinga forest patches. We

Pushing the limits of C3 intrinsic water use efficiency in Mediterranean semiarid steppes: Responses of a drought‐avoider perennial grass to climate aridification

Functional Ecology, Volume 38, Issue 4, Page 955-966, April 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Intrinsic water use efficiency (WUEi) reflects the trade‐off between photosynthetic carbon gain and water loss through stomatal conductance and is key for understanding dryland plant responses to climate change.
