GIZ - Nexus perspective in the water sector
Advisory services to BMZ and BMU for international agenda setting
Regional
National
Local
Advice to governments for considering interdependencies between water, energy and agriculture in planning processes e.g. assist government on for policy coherence and Nexus-framework-conditions.
Large-scale implementation of innovative solutions e.g. agricultural water management, integrated water resources management in cities, solar-power desalination and irrigation.
Support coordination between river basin organisations and regional energy actors
GIZ provides advisory services for international agenda setting, primarily to two Federal Ministries BMZ and BMU. e.g. by formulating the German position in the Post 2015 – SDG discussion
Support supra-national and regional coordination e.g. between River Basin Organisations and Regional Water Actors
