yields of 8.4 t ha?1 and net profits of US$1097 ha?1, compared with 6.5 t ha?1 and US$675 ha?1 for medium- yield farmers. In the New Lands, the yield gap was more pronounced, with high-yield farmers achieving average yields of 7.5 t ha?1 compared to 4.63 t ha?1 for medium-yield farmers, highlighting a significant opportunity to increase productivity. Determinants for yield and profit varied across governorates, indicating need for governorate-specific strategies to sustainably close yield and profit gaps. Water productivity, NUE, and labor productivity were notably lower, while production cost showed no strong correlation with yield and was negatively correlated with greenhouse gas emission intensity (GHGI). Raised bed planting improved NUE by 29 %, increased water productivity by 18 %, and reduced GHGI by 15 % compared with conventional flat planting.
SIGNIFICANCE:
Adopting context-specific agronomic practices that combine integrated-fertilization, efficient irrigation, suitable varieties, and raised-bed planting can enhance agronomic gains while reducing environ
mental footprints. When tailored to local yield-limiting factors, these solutions provide a sustainable pathway to narrow yield and profit gaps. Scaling data-driven solutions, supported by enabling policies and effective extension systems, offers viable option to strengthen wheat self-sufficiency in Egypt and similar irrigated drylands.

The paper provides a historical review and a contemporary snapshot of pastoral systems in Tunisia, exploring the dynamics of change in pastoral landscapes and territories and their respective drivers and outcomes. The core idea is to recognize the emerging diversity of pastoral systems in terms of structure and transformation, and thus to approach them analytically from a perspective of dynamic transition. The paper utilizes an agroecological gradient of transformation to illustrate the inherent agroecological nature of pastoralism by examining the different trajectories of these systems. The ongoing “hybridization” of pastoralism in South Tunisia is characterized by the emergence of diverse forms of pastoral activities and contexts. These novel forms of pastoralism occasionally diverge from certain agroecological principles. The paper also elucidates key factors that propel these trajectories and divergences of certain forms of pastoralism from agroecology. To this end, key elements and attributes from the political economy framework, with a particular focus on market and labor dynamics in pastoral areas, social metabolism, organizational structures, policies, institutions, and natural resource management, were discussed. The analysis shows how some of these drivers have contributed to the formation of a novel configuration of pastoralism.

This paper investigates Tunisia’s agricultural policy landscape by examining how national policies on wheat and forage contribute to or hinder agroecological transition. It maps policy actors, assesses their alignment with strategic priorities, and analyses policy development processes. The study employs the Kaleidoscope Model as a framework for analysis, drawing on its five key stages of the policy cycle. Qualitative and semiqualitative methods are used to identify actors, track policy changes, and analyze policy engagement and failure. The findings reveal that Tunisia’s wheat-focused policies prioritize short term stability over sustainable, diversified agriculture, marginalizing forages and threatening long-term ecological resilience.
