Kech River


The Kech River holds historical significance, serving as a lifeline for Balochistan for centuries. It has sustained agriculture, supported local economies, and provided a habitat for diverse flora and fauna. Unfortunately, the river is now facing pollution issues due to agricultural runoff and untreated domestic wastewater, jeopardizing its ecological integrity and the well-being of surrounding communities.

The Kech river bioremediation project is a vital response to this ecological crisis. By implementing bioremediation technology, we contribute to the river health and to safeguard its historical significance. This also creates benefits for local communities dependent on the Kech River for agriculture and livelihoods, ensuring a better water quality source. Moreover, the project aligns with broader sustainability goals, contributing to global efforts in reduce pollution, capturing atmospheric carbon, and mitigating climate change.

Local team

The team driving the Kech River Project is led by Dr. Haneef Ur Rehman, who serves as a Professor in the Department of Natural and Basic Sciences at Turbat University. Working alongside him is Adnan, who contributes as Field Researcher while Muhammed and Feroz are laboratory interns. They are united in their mission to create a greener and more sustainable future for the Kech River and beyond.

The project delivers a long-lasting climate impact ensured by continuous and efficient monitoring
Monitoring river bioremediation performance
Spatial and temporal assessment of water quality along the river monitoring stations considering the evolution of biological and physicochemical parameters to evaluate water quality during and after the bioremediation.

Also, satellites images and RS tools are used to monitor microalgae blooms and nutrients evolution along the river.
Carbon sequestration verification and validation
A combination of MRV techniques are used to report the carbon storage in riverbed soils and GHG mitigation
Field measurements
In-situ field measurements to verify and validate microalgae-biomass deposition and accumulation and its contribution to carbon storage in the riverbed soil.
Modelling and simulation
Application of models to simulate microalgae behaviour in the river-estuary system and quantify biomass contribution to the carbon pool.

Every river project listed on the Liquid Trees Marketplace must align with our Evaluation Criteria to ensure project quality. To monitor a river bioremediation project, Liquid Trees uses remote sensing and geographic information systems along with field measurements to monitor and assess microalgae biomass and nutrient evolution along the target river.

Rivers of resilience: unleashing nature's potential in the Kech district

Amidst the serene landscapes of Kech district, the Kech River embarked on a transformative journey. Enduring years of pollution, this lifeline faced significant challenges. Recognizing the urgency of the situation, we took upon ourselves the responsibility of revitalizing the river and nurturing its potential.

Through biological river bioremediation and water quality monitoring, we aim to improve water quality. The remediation of the river's ecosystem not only ensures clean water for the resilient community of Dasht but also heralds a beacon of hope for the broader region. By nurturing the potential of the Kech River, we strive to set an example of harmonious coexistence between nature and human endeavors.

The bioremediation of the river's ecosystem ensures better water quality for the resilient community of Dasht and also heralds a beacon of hope for the broader region.

Agricultural run-off decreases water quality at Kech River
Economic conditions

Balochistan, the home of the Kech River bioremediation project, is a province situated between Pakistan, Iran, and Afghanistan. This region has a rich cultural heritage and abundant natural resources including mineral and hydrocarbon deposits. Despite its resource potential, Balochistan has lagged behind other provinces in terms of economic development. The province's economy mainly relies on agriculture and mining. Balochistan ranks low on the human development index, with significant challenges in access to safe drinking water, electricity, and education. With around 70% of the province's population residing in rural areas, the rural nature of Balochistan further contributes to the economic challenges faced by the region.

The Kech River bioremediation project aims to support the local economy by recovering river water quality and employing local talent. Thus, this project plays a crucial role in fostering economic growth, social progress, and a better future for Balochistan.

Fish population conditions

The coastal regions of Balochistan are facing significant challenges in maintaining their fish population due to domestic, agricultural, and sewage pollution. The adverse effects of climate change, combined with inadequate waste management practices, have further intensified these challenges, impacting local fishermen to sustain their living. Urgent measures are needed to reverse the water qialuty and security concerns along with the decreasing fish populations.

The Kech River project aims to address these environmental challenges. By leveraging the unique properties of diatoms, we eliminate pollutants from water and create local employment opportunities, fostering a sense of ownership among the people of Balochistan towards the Kech River project.

Trash and plastic pollution

With the aim of trash and solid waste removal from the Kech River, we plan to install interceptors along the river for their effective collection and removal. This proactive approach contributes to protecting the river ecosystem, creating a cleaner environment for both the local community and the aquatic life that depends on the river. By undertaking these initiatives and engaging the local community, we aim to provide a better future for Balochistan and its people.
