Land degradation, caused by human-induced processes such as agricultural practices, deforestation and overgrazing, poses a significant threat to countries worldwide, including Tunisia. Agroecological farming well the broader paradigm of agroecology transform food systems, are considered important solutions address challenges drivers land degradation. This paper aims explore potential future transformations in country institutional factors hindering transformations. We build on six domains Anderson et al. (2021) analysis literature, use soil governance an example. Building primary secondary data, we find that current landscape Tunisia is largely disabling effective protection The provides insights into formal informal institutions can be targeted more enabling environment for

Oxygen and hydrobiological profiles of homemade manure-based tea in North Africa

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Feb. 11, 2025

Abstract Homemade manure tea (HMT) is commonly used in North Africa to enhance crop yields. Yet their physicochemical and biological characteristics remain poorly understood. This study evaluated oxygen hydrobiological profiles of three types HMT (bovine, ovine poultry based, respectively noted HMTb, HMTo, HMTp) compared them control solutions water supplemented with soluble NPK fertilizer. For these HMT, were measured daily over a 7-day incubation period repeated, identical experiments, each comprising randomized treatments five repetitions per treatment. Our results show that all rapidly transitioned hypoxic conditions the first 24h, shifting anoxia between day 2 7 depending on type. anoxic environment promoted denitrification led elevated NH 4 + concentrations, suggesting presence anammox microaerobic processes. Particulate organic matter contents bacterial densities highest HMTp, while ciliate HMTb. These findings underscore bioactive potential as fertilizers, HMTp showing favorable nitrogen profile beneficial for agricultural applications. To maintain aerobic longer reduce losses greenhouse gas emissions, we recommend passive or mechanical aeration, applying during cooler hours, stabilizing pH HMT. offers valuable insights refine preparation protocols, enhancing use fertilizers.

Irrigation and agroecology: a scientific mismatch? A literature review

Agroecology and irrigation practices systems, which are essential to achieve sufficient sustainable agricultural production, have seldom been jointly rationalized. This review aims gain insight into the current state of art research at cusp these two fields. Relevant scientific literature from standpoints, that water communities, was analyzed. Thirty-eight papers queried Clarivate Web Science were quantitatively qualitatively Most confined budget analyses cropping systems or experimental manipulations. Only a small number found acknowledge co-existence agroecology highlight offers an opportunity for agroecological systems. Links between higher levels (farm, territorial, food system) analyzed in scant papers. We suggest oversights could be due fact fields – addition associated policies realities different narratives, goals, approaches, scales, involved actors. Research needs delve much deeper by designing is tailored complexity while striving enhance ecological processes provision multiple ecosystem services.
