Unraveling the spatial patterns of water conflicts in Africa through a multi-scale lens Open
In Africa, water conflicts are increasing, posing significant threats to livelihoods. Unraveling the spatial pattern and drivers of water conflicts is essential for anticipating risks and targeting water policies. However, there is a lack …
Simulating farm structural change dynamics in Thessaly (Greece) using a recursive programming model Open
Although the policy impacts on farms accumulate year by year, most farm decision models focus on short-term decisions, evaluating policies based on snapshots. Structural changes are gradually built; therefore, farm decision models should c…

<i>“Fruit basket upset”</i>: spatially explicit crop mixture responses to climatic and economic pressures Open
Purpose The choice of crops to produce at a location depends to a large degree on the climate. As the climate changes and food demand evolves, farmers may need to produce a different mix of crops. This study assesses how much cropland may …

Linguistic diversity, climate shock, and farmers-herder conflicts: Implications for inclusive innovations for agro-pastoralism systems Open
In Africa, farmer-herder conflicts can be partially attributed to linguistic differences that impede communication and conflict resolution. This tension can be further amplified by climatic shocks that increase incentives to fight for reso…

The potential impact of banana Xanthomonas wilt on food systems in Africa: modeling scenarios of policy response and disease control measures Open
Banana Xanthomonas wilt (BXW) is one of the most important diseases threatening banana production in Africa south of the Sahara (SSA). In this study, we examine the potential impacts of BXW on banana production, demand, and food security i…
The European agro-economic model AROPAj Open
This publication presents the European agro-economic AROPAj model. Throughout recent years the model has been adapted to suit FADN data and the expansion of the European Union (EU ). The revised model, which is presented here, is based on …

A systematic review on trade-off analysis in agriculture Open
Achieving multiple sustainable development goals simultaneously demands managing agricultural resources for different objectives and actively considering how these objectives compete (trade-offs) or complement (synergies). Trade-off analys…
Models and muddles: comment on ‘Calibration of agricultural risk programming models using positive mathematical programming’ Open
There is an emerging strand in the agricultural economics literature which examines the calibration of risk programming models using the principles of Positive Mathematical Programming (PMP). In a recent contribution to this journal, Liu e…
Farm‐level impacts of the <span>CAP</span> post‐2020 reform: A scenario‐based analysis Open
We analyze the farm‐level economic and environmental impacts of the post‐2020 reform of the Common Agricultural Policy (CAP) of the European Union, examining six scenarios constructed around the budget allocated to eco‐schemes and the stri…
Economic and environmental effects of the post-2020 CAP reform proposal in Spain: a farm level assessment Open
With the purpose of fostering better environmental performance of European farms, the CAP post-2020 reform will introduce new subsidy schemes to allocate direct payments that are conditional to environmental measures. In particular, the Co…
Thinking big for smallholder agriculture: realizing agricultural potentials in changing times Open
Recent advances in approaches to quantitative strategic foresight have enabled new insights into understanding potential futures of the agriculture sector. Quantitative foresight approaches facilitate understanding of different plausible s…
SUPREMA - SUpport for Policy RElevant Modelling of Agriculture Open
Impact assessments for agriculture are partly based on projections delivered by models. Sectoral policies are becoming more and more interrelated. Hence, there is a need to improve the capacity of current models, connect them or redesign t…
CGIAR modeling approaches for resource‐constrained scenarios: II. Models for analyzing socioeconomic factors to improve policy recommendations Open
International crop‐related research as conducted by the CGIAR uses crop modeling for a variety of purposes. By linking crop models with economic models and approaches, crop model outputs can be effectively used as inputs into socioeconomic…
Pesticide Use Practices in Root, Tuber, and Banana Crops by Smallholder Farmers in Rwanda and Burundi Open
Misuse and poor handling of chemical pesticides in agriculture is hazardous to the health of farmers, consumers, and to the environment. We studied the pest and disease management practices and the type of pesticides used in four root, tub…
