Researchers Recommend System Dynamics Approach in the Management of Wetlands

Published

on

Wetlands provide goods and services like water and fish as well as water purification and flood mitigation. However, they are used unsustainably leading to degradation. The search for fertile soils and water for animals and agricultural use, as well as papyrus for commercial purposes has heightened degradation. According to a study conducted by researchers from the College of Agricultural and Environmental Sciences (CAES), Makerere University and Michigan State University, food and economic security are the main drivers of encroachment and the main activities carried out within the wetland are farming (40%), vegetation harvesting (25%) and fishing (24%).  Although a number of interventions have been made to protect wetlands, encroachment persists. To minimize the challenge, it is important for all stakeholders to understand the structure of the wetland system and its linkage with livelihood activities.

Through a project titled, “Participatory Modelling for Livelihood Security and Ecological Integrity in a Ugandan Wetland-Agricultural System”, the researchers led by Dr Ellen Kayendeke from the Department of Environmental Management, CAES, and Prof. Laura Schmitt Olabisi from Michigan State University conducted a survey among wetland users on the drivers of wetland degradation and how this impacts ecosystem services.  The overall objectives of the project were; i) to generate information about the causal links and feedback mechanisms between wetland management and livelihood activities, and ii) to create an improved and shared understanding of the wetland-agricultural system structure among the stakeholders. Other members on the project included Prof. Frank Kansiime from the Department of Environmental Management; and Prof. David Mfitumukiza from the Department of Geography, Geo-informatics and Climatic Sciences, CAES, Makerere University.

According to the research findings, wetland degradation impacts long-term agricultural productivity, which then perpetuates a cycle of food insecurity and poverty. The short term effects of encroachment include reduction in wetland flora and fauna, and reduced ability to supplement food needs. The long term effects include reduction in soil fertility and low yields.

Disseminating their findings to stakeholders on 24th August 2022, the researchers noted that wetland users are aware of the impact of degradation on ecosystem services, but continue to encroach on wetlands. The encroachers claim they cannot vacate the wetlands because of a lack of alternative livelihoods. The researchers advise that efforts to regulate wetland use and educate stakeholders on wise use of wetlands should be complemented with support of alternative livelihoods.

The CEO of Eco Brixs, Mr. Andrew Bownds (2nd R) with the Makerere University team led by the Vice Chancellor, Prof. Barnabas Nawangwe (3rd R) after the meeting on 8th May 2024. Rotary Peace Centre, Frank Kalimuzo Central Teaching Facility, Makerere University, Kampala Uganda, East Africa.

Poor waste disposal remains one of the biggest challenges in Uganda pausing a number of environmental and health risks. According to the Ministry of Water and Environment, plastic waste is becoming disastrous to urban and rural areas due to poor disposal practices. All store purchases are packaged in polythene bags, and without proper disposal, plastic garbage can be seen everywhere. During the rainy season, they are washed into water channels, where they block drainage. Single-use packaging for soda, water, and other drinks results in mountains of garbage heaping up in legal and illegal dumpsites – The Independent Magazine, 30th May 2022.


As a measure to improve plastics waste management in the country, Eco Brixs has reached out to Makerere University to collaborate in addressing the challenge. On 8th May 2024, the CEO, also Co-Founder of Eco Brixs, Mr. Andrew Bownds held a meeting with Makerere University officials led by the Vice Chancellor, Prof. Barnabas Nawangwe in which they brainstormed on different areas for collaboration.

Proposed areas for collaboration

  1. Research, Eco Brixs seeks to collaborate with Makerere University in Product Testing. Eco Brixs is producing new products monthly and requires lab tests to support UNBS certification. The Company also seeks to collaborate with Makerere in Environmental Research. The Company intends to work with PhD students to complete focused research on plastic pollution and the recycling process.
  2. Internships – Eco Brixs has had 50 students complete internships and would love to grow that with Makerere.
  3. Be Makerere Official Recyclers – Eco Brixs seeks to be the recycler of Makerere University. Suggestions were made to jointly source funding to address the challenge and to set up a plastic waste collection centre at Makerere University.
