The United Nations Office at Nairobi (UNON), on behalf of Climate Technology Centre and Network (CTCN), United Nations Environment Programme (UNEP) invites qualified interested firms to submit Expression of Interest (EOI) to participate in the upcoming solicitation for provision of technical assistance implementation of the Technical Assistance on "Groundwater monitoring system for managing aquifers as a tool for climate change adaptation planning in Belize." The United Nations Environment Programme (UNEP) on behalf of the Climate Technology Centre and Network (CTCN) requires the services of an institution to deliver the technical assistance as approved by National Designated Entity from Belize. The overall objective of the Technical Assistance is to design a groundwater monitoring system useful for the National Hydrological Service and government agencies in Belize to identify risks for the water supply for diverse groundwater users in Belize. The project outcome is to increase climate resilience in Belize by designing a groundwater monitoring system to assess and control the impacts of groundwater abstraction and contaminant loads to Belize aquifers through monitoring aquifers´ response and quality trends. Some of the expected outcome, outputs and activities are; • Development of a detailed work plan and related communication documents • Map Stakeholders and establish a Stakeholder Working Group • Assess groundwater availability and demand based on the available technical information. • Analysis of the current and projected economic activities and the water demand on groundwater sources. • Map the groundwater resources of Belize in the prioritized area of the New River watershed. • Design a fully integrated groundwater monitoring system that will enable Belize to manage groundwater resources in the priority area. • Enabling factors for implementation: financing, institutional settings and capacity building • Training with relevant entities in the sector The complete details of the requirement will be provided in the tender documents that will be issued to bidders after this request for EOI is closed.
