Prof. Brück erforscht die Wechselwirkungen zwischen bewaffneten Konflikten, Klimaschocks und Ernährungssicherheit in fragilen Kontexten, insbesondere in Afrika. Seine aktuelle Heisenberg-Professur (2022–2027) konzentriert sich darauf, wie Krisen die Ernährungssysteme, Lebensgrundlagen und soziale Strukturen von Haushalten und Gemeinschaften beeinflussen – mit besonderem Fokus auf Geschlechterdimensionen und Ungleichheit. Durch rigorose empirische Studien (Panel-Surveys, randomisierte Feldexperimente, Multi-Länder-Analysen) liefert er evidenzbasierte Erkenntnisse für die Gestaltung von Anpassungs- und Resilienzmaßnahmen in Agrifood-Systemen sowie für humanitäre und Entwicklungspolitik. Seine Arbeiten sind relevant für internationale Organisationen, Regierungen und NGOs, die in Konflikt- und Krisengebieten tätig sind, sowie für die Agrar- und Ernährungspolitik unter Bedingungen von Polykrisen.

This paper studies how conflict affects household resilience capacity and food security, drawing on panel data collected from households in Palestine before and after the 2014 Gaza conflict. During this escalation of violence, the majority of the damages in the Gaza Strip were concentrated close to the Israeli border. Using the distance to the Israeli border to identify the effect of the conflict at the household level through an instrumental variable approach, we find that the food security of households in the Gaza Strip was not directly affected by the conflict. However, household resilience capacity that is necessary to resist food insecurity declined among Gazan households as a result of the conflict. This was mainly due to a reduction of adaptive capacity, driven by the deterioration of income stability and income diversification. However, the conflict actually increased the use of social safety nets (expressed in the form of cash, in-kind or other transfers that were received by the households) and access to basic services (mainly access to sanitation) for the households exposed to the conflict. This finding may be related to the support provided to households in the Gaza Strip by national and international organizations after the end of the conflict. From a policy perspective, the case of the conflict in the Gaza Strip demonstrates that immediate and significant support to victims of conflict can indeed help restore resilience capacity.

Abstract This article introduces a special issue on the micro-level dynamics of mass violent conflict. While most analyses of conflict typically adopt a regional, national or global perspective, often using country-level data, this special issue takes an explicit micro-level approach, focusing on the behaviour and welfare of individuals, households and groups or communities. At a fundamental level, conflict originates from individuals' behaviour and their repeated interactions with their surroundings, in other words, from its micro-foundations. A micro-level approach advances our understanding of conflict by its ability to account for individual and group heterogeneity within one country or one conflict. The contributors to this special issue investigate the nature of violence against civilians, the agency of civilians during conflict, the strategic interaction between civilians and armed actors, the consequences of displacement, the effectiveness of coping strategies and the impact of policy interventions. The core message from these articles is that in order to understand conflict dynamics and its effects on society, we have to take seriously the incentives and constraints shaping the interaction between the civilian population and the armed actors. The kind of interaction that develops, as well as the resulting conflict dynamics, depend on the type of conflict, the type of armed actors and the characteristics of the civilian population and its institutions.

In our brief review, we take stock of the emergence, in the last decade, of the “microeconomics of violent conflict” as a new subfield of empirical development economics. We start by de-bunking common misperceptions about the microeconomics of conflict and identify several contributions to economic theory and, in particular, to empirics, methods and data. We also show how the subfield is enriched through cooperation with scholars working in related disciplines. We expect future work to contribute inter alia to the evidence base on peacebuilding interventions, the development of post-conflict institutions, the behavior of firms in conflict areas and the role of emotions in decision-making. We note a disconnect between the rapidly evolving academic subfield on the one hand and the relatively limited use of knowledge thus generated by humanitarian and development organisations and policy makers working in and on conflict-affected areas. We conclude by suggesting that teaching in economics and the discipline-specific JEL codes have not yet kept pace with this recent intellectual development.
