Job Description


Solar Salt Farming (Mining) Engineer and Hydrologist

Location of Assignment: Dar es Salaam, Tanzania and Pemba Island, Zanzibar

Proposed Level of Effort: approximately 4 weeks

Anticipated Start Date:  July 2019

Anticipated End Date: August 2019


The Tanzania Enabling Growth through Investment and Enterprise Program (ENGINE) is a USAID-funded Feed the Future activity that aims to streamline and enhance many of the regulatory, informational and financial channels that encourage domestic and foreign investment in the southern mainland agricultural regions of Mbeya, Morogoro, and Iringa, and in Zanzibar.

ENGINE works at the district level, using a broad-based approach to engage with district Local Government Authorities (LGAs), private sector associations, business development service providers, financial institutions and small and medium enterprises.

Opportunity Statement

Tanzania produces approximately 93,000 metric tons of Salt (up from 34,000 MT in 2012) and imports 143,000 metric tons primarily from Kenya (72%), Zambia (17%) and India (11%) with a 5-year imported compounded annual growth rate (CAGR) of 28% in quantity. While salt in Tanzania is primarily produced on the mainland and through solar evaporation, the USAID-EGNINE Project aims to focus its efforts on Pemba Island in Zanzibar in partnership with the Swahili Coast Salt Company whose business plan is to procure salt from 72 farms on the island consisting of over 500 individual farmers.Today, these 72 farms on Pemba produce approximately 2,000MT of salt per annum, but have a high capacity for further production growth.

The USAID-ENGINE Project, in support of this private sector investment led by the Swahili Coast Salt Company, aims to encourage an increase in the productive capacity of salt cultivation on Pemba thereby improving the economic opportunities for the farmers. The objective is to: reduce imports, improve the opportunity for production and sale of high-quality salt for human consumption from Pemba Island to various new markets.
