Abstract

Content of image described in text.

Plastic pollution is a growing challenge in the Horn of Africa, driven by rapid urbanization and inadequate waste management infrastructure. This study compares plastic waste management policies, practices and challenges across four countries: Ethiopia, Eritrea, Somalia and Djibouti. Despite shared socioeconomic and geographic characteristics, these countries exhibit significant differences in governance structures and institutional capacity, which shape policy effectiveness and implementation outcomes. The findings show that Ethiopia has the most developed policy framework, incorporating integrated approaches such as life cycle management and extended producer responsibility through coordinated governance mechanisms. Somalia has introduced regulatory measures in recent years; however, progress remains constrained by fragmented authority and weak enforcement. Eritrea applies a centralized, state-controlled regulatory model emphasizing strict compliance, though limited transparency and economic incentives restrict broader effectiveness. In contrast, Djibouti addresses plastic waste primarily within its municipal management framework, relying heavily on international partnerships and outsourced services. Across the region, common challenges include weak enforcement capacity, fragmented institutional mandates, inadequate infrastructure and limited stakeholder engagement, with urban areas generally demonstrating stronger implementation than rural regions. Despite these constraints, significant opportunities exist to strengthen regional plastic governance through harmonized policy approaches, expanded producer responsibility systems and a transition toward circular economy strategies. Overall, the study highlights the critical role of governance structures and institutional capacity in shaping environmental policy outcomes and emphasizes the need for coordinated, regionally aligned approaches to improve plastic waste management in the Horn of Africa.

Cover letter

Dear Editors,

I am pleased to submit our manuscript entitled “Plastic Waste Management in Horn of African Countries: A Comparative Evaluation of Policies, Practices, Challenges, and Limitations” for consideration in Cambridge Prisms: Plastics.

This study provides a comparative assessment of plastic waste management governance in the Horn of Africa countries, namely: Ethiopia, Eritrea, Somalia, and Djibouti. While these countries share similar socioeconomic and geographic contexts, their governance structures and institutional capacities differ substantially. Our analysis shows how these differences shape policy design, enforcement, and overall effectiveness. The manuscript examines national plastic bans, Extended Producer Responsibility (EPR) frameworks, centralized and decentralized regulatory systems in the countries, and the role of donor-supported systems. It also identifies common regional barriers, including weak enforcement, fragmented mandates, infrastructure limitations, and uneven implementation between rural and urban areas.

Beyond comparison, the paper offers a regional perspective on harmonizing plastic governance in the Horn of Africa. It highlights opportunities for strengthened legislation, EPR expansion, improved coordination, and a transition toward circular economy approaches. Given the growing global attention to plastics governance in low- and middle-income countries, we believe this work contributes valuable empirical and policy-relevant insights aligned with the interdisciplinary scope of Cambridge Prisms: Plastics.

This manuscript has not been published elsewhere and is not under consideration by any other journal. All authors have approved the submission and have no conflicts of interest to declare.

Thank you for considering our manuscript. We appreciate your time and look forward to your response.

Sincerely,

Tadele Assefa Aragaw, PhD

Comments

This study comparatively evaluates the policies, practices, challenges, and limitations of the plastic waste management in the countries of the Horn of Africa. The topic is meaningful. However, the language requires further polishing. Specific comments are provided below:

1.Throughout the manuscript, the order of different countries is presented needs to be consistent.

2.In the introduction, the manuscript provides a detailed account of the severity of plastic pollution in Africa and the Horn of Africa, and also notes policy differences among the countries. However, it does not clearly state the purpose and significance of this study in the final paragraph.

3.In Section 3. Case study. The cross-country comparison lacks a clear hierarchical structure. I suggest that the implementation practices of the four countries should be organized into a uniform structure according to 1) lead implementing institutions and levels (central vs. local); 2) enforcement mechanisms and consistency (urban-rural differences, formal/informal sectors); 3) models of social participation (NGOs, communities, private sector); 4) degree of dependence on international aid.

4.In lines 196-199, the sentence cites “The New Humanitarian (2002)”, but the timeline is inconsistent with the first sentence of that paragraph, which states: “ Eritrea has enacted measures to ban the manufacture, importation, sale, and use of plastic bags through Proclamation No. 165/2005...” Please verify the references.

5.In Section 4. Implementation practices and Section 5. Challenges and limitations, content repeatedly mentions issues such as “inconsistent enforcement”, “limited resources”, and “dependence on international partners”. It is suggested that the implementation section describe only what has been done, while the challenges section systematically analyze the reasons why implementation has been less effective.

6.In Implementation practices, the “informal economy” is mentioned only in the Somalia, and in Table 1, the “informal sector” is noted only in Ethiopia.

7.In lines 238-241. If this legislation was proposed in 2025, the manuscript should clarify whether it has been passed, entered into force, or been set aside. Vague passive phrasing should be avoided.

8.In lines 275-276. This statement requires specific evidence or a citation to define the criteria for “strong presence”.

9.The uniqueness of the Horn of Africa has not been sufficiently explored. Apart from Ethiopia, the other three countries have long coastlines. Although the manuscript mentions shipping routes in the Red Sea and the Indian Ocean, it does not provide in-depth analysis, instead referring only superficially to “marine litter” and “MARPOL enforcement”. It is recommended that this be made more specific, for example, by addressing coastal plastic waste management and whether quantitative data on beach clean-ups (such as kilograms of litter per kilometer of coastline) are available.

10. In line 307. Microplastics are mentioned only here, and without further explanation. Are there any relevant data on microplastics available from other countries?

11. In Section 6. Recommendation and future perspective, I suggest providing specific and actionable recommendations tailored to each country, rather than generic suggestions.

Major revisions:

I would like to thank the authors for a timely synthesis of the legal frameworks related to plastics that exist in the HoA region, especially at a time when international law is struggling to come to agreements of how plastic pollution can be addressed. The efforts of individual countries go a long way in protecting the health of the environment and the people. While the current manuscript attempts to list and discuss the existing laws and challenges with their implementation, not enough is done to actually review the practicality of implementation, challenges with individual countries, the possibility of regional agreements, EPR schemes, waste recycling laws, and other challenging aspects, such as the integration of informal waste pickers into the waste management workforce. Such work should go beyond just listing the laws as they exist to synthesizing new knowledge on how such laws can be operationalized. To assist the authors in achieving this, the following are recommended:

The study objectives rightly attempt to evaluate “plastic waste management policies across these countries, analyzing their design, implementation, and outcomes, and highlighting lessons learned, barriers encountered, and pathways for regional coordination and policy harmonization”. However, only about half of these objectives are achieved. There is nothing in the manuscript, for instance, about specific barriers to policy implementation, or even policy harmonization across the region. Therefore, authors should add a section on the similarities in terms of barriers, e.g., political barriers, instability, etc., investment, and translation of policy to impact.

The policies, while elaborate, are operationalized by specific frameworks. For instance, the authors show that the National Plastic Strategy Action Plan in Ethiopia operationalizes the Solid Waste Management Proclamation No. 513/2007. However, this is not clearly presented in the manuscript. The authors should clearly differentiate between the laws/or policies that have been passed/gazette and the frameworks that deal with the implementation of such laws – clear differentiation of hard laws and soft law instruments is required. That is, under Section 3, authors should discuss the Laws and Policies, while under Section 4, the authors should show the specific measures by which these are policies and/or laws are implemented. At the moment, there is some level of redundancy and repetition in these two sections.

In addition to the comment above, there is a missing discussion on how the state/country/regulatory agencies deal with the contraventions of the set policies. Most countries impose a fine on both consumers and producers, e.g., contraventions in Kenya and Rwanda carry a prison sentence. How do the countries of focus enforce their laws?

The authors note in the discussion that in some large cities, such as Addis Ababa, enforcement may be stronger. Is this influenced by the agencies responsible for implementation or the environmental degradation in this region when compared to the outskirts? This needs further details for all the focus countries, especially if these differences are complex.

Having mentioned earlier that there is currently an ongoing discussion about passing law instruments to address plastic pollution in international waters, specific conventions already exist that deal with specific aspects of plastic pollution, from MARPOL, the Stockholm Convention, the Basel Convention, etc. It is not discussed in the current manuscript whether any of these countries are signatories/have ratified any such conventions. It is therefore recommended that the authors add a section on international conventions that the countries of concern are signatories to, how they implement such conventions, and/or how these conventions have informed their local policies, and challenges related to such implementation.

Closely related to the comment above, the authors are encouraged to look at regional cooperation, as it is one of the objectives of this manuscript, within this region. Are there shared water resources that are regionally governed? If so, do the policies governing them include plastics? The East African community, for instance, has guidelines for the polyethylene materials commerce. Are there such guidelines for this region?

Most of the African countries do not have the capacity for production and recycling. For this region, it would be interesting for the authors to highlight, and perhaps detail, how the countries deal with imports and interstate commerce. Furthermore, the question of recycling status, capacity, and waste management needs to be discussed in detail, i.e., are the current policies dealing with the environmental problems sufficiently, if at all?

Minor revisions:

In the abstract, only two proclamations are listed, while the manuscript focuses on four countries, which later are shown to have their specific laws. I suggest that the authors only summarise the findings in the abstract and only list and detail the specific laws in the content of the manuscript.

Line 60 - 63: “However, despite the growing adoption of policies…” Some context is lost with this sentence when reading from the previous sentence. I would suggest removing the next few sentences until “The study, therefore, addresses the gaps…”.

Methodology: The keywords listed here are too general and would not yield any specific papers or literature that is relevant to compiling such a manuscript. Authors are advised to revise this section to add relevant keywords/phrases that ensure reproducibility.

Line 87: The insertion of Kenya here is confusing since it is not part of the region of concern. If this was a mistake, please replace it with Eritrea.

Line 287: Please start the paragraph with “In Ethiopia…”

Comments

Please address the following points when preparing your revised submission:

Line 32. Please consider deleting the word “marine” as terrestrial ecosystems are also affected by plastic pollution.

Lines 55-78. There is overlap between the text in these sections, which needs to be rationalised.

Line 85. Avoid the use of the word “like” here. Perhaps use “including” instead?

Line 91. Further explanation of MSSD approach would be beneficial.

Line 108. The use of the phrase “good initiatives” seems out of place.
