HEKS initiates and supports development cooperation projects to combat poverty and injustice in over 30 countries on four continents. HEKS also provides humanitarian aid worldwide for the victims of disasters and armed conflicts and supports church-based diaconal work in Eastern Europe and the Middle East.
Building resilience to climate and disaster risk is a core topic of  HEKS. Building on the experiences and knowledge of the beneficiary communities in mitigating and preparing for shocks as well as adapting to long-term stresses, HEKS develops locally adapted strategies to reduce climate and disaster risk and to strengthen the resilience of its beneficiary communities. In Switzerland and worldwide HEKS is advocating for Climate Justice.
