This process of regional alignment has, to a degree, incorporated a more pluralistic approach that considers and acknowledges that multiple seed systems make up the seed sector and that national legal systems may contain different innovations and flexibilities. With deeper continental integration foreseen under the African Continental Free Trade Area, the focus on regional alignment of agricultural rules in Africa has increased. While this presents an opportunity for policy and regulatory change in support of seed sector development, deeper study is warranted of how regional and national policy and regulatory systems align and where differences could advance greater equity in seed systems.</div></div><div><h3>Objective</h3><div>This study aims to analyze and compare the legal and regulatory dimensions of seed sector development in Sub-Saharan Africa by identifying areas of convergence and divergence across both law and practice in national legal systems.</div></div><div><h3>Methods</h3><div>The study applies a relatively novel method—Regulatory Systems Mapping—that allows for both comparative and contextual analysis. The methodology focuses on four qualitative comparative criteria (efficiency, legal design, implementation, and flexibility and equity) to highlight stakeholder experiences and good practices in seed sector development. The method is applied to three countries (Ethiopia, Rwanda, and Uganda), all of which are members of the Common Market for Eastern and Southern Africa and have reformed domestic law in line with various regional agreements.</div></div><div><h3>Results and conclusions</h3><div>The study finds both differences and similarities between the three countries in terms of practices, flexibilities, alignment, needs, and gaps in the legal and regulatory dimensions of seed sector development, particularly with respect to areas in which written law differs from stakeholder experience. These findings suggest the need for several national-level interventions and a review of regional rules and procedures to integrate flexibility and stakeholder priorities in legal and regulatory design and implementation.</div></div><div><h3>Significance</h3><div>The study not only contributes to the growing body of literature on African policy and regulation for seed sector development but also details a novel methodological approach to comparing seed regulatory systems, with emphasis on analytically isolating intervention points, legal innovations, and fit-for purpose pluralistic approaches. This analysis provides the kind of evidence that policymakers need to improve regulatory systems to better address dimensions such as flexibility and equity that reflect farmers' needs, reduce costs, and increase participation in seed systems.</div></div>","PeriodicalId":7730,"journal":{"name":"Agricultural Systems","volume":"228 ","pages":"Article 104351"},"PeriodicalIF":6.1,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143907095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biogas is an interesting technology in this respect, however, the possible farm-level economic impacts from investing in a biogas-based system are not well understood, yet they are decisive to understand farmers' incentives for adoption.</div></div><div><h3>OBJECTIVE</h3><div>The objectives are to i) develop a scenario which allows the farms to become fossil-free in their input use, ii) assess the farm-level economic consequences of adoption and iii) quantify change in global warming potential in a 100-year period (GWP<sub>100</sub>) from the biogas-scenario.</div></div><div><h3>METHODS</h3><div>We use a stochastic partial budgeting approach to simulate farm-level economic benefits and costs associated with changes and uncertainty related to economic effects. We also use life cycle assessment for the quantification of the climate effects, which enable us to examine the potential climate impact in reduction of fossil-based inputs in baseline scenario by transitioning to the biogas scenario. The study is based on simulation for a hypothetical dairy farm with 300 milking cow and a corresponding 325 ha of arable land that produces 75 % mixed grass and 25 % clover.</div></div><div><h3>RESULTS AND CONCLUSIONS</h3><div>The result shows that transitioning to a biogas-based system will yield an estimated deterministic net annual benefit of 1035 SEK for the hypothetical farm. However, when considering simulated scenario, the net annual benefit could be negative, amounting −5398 SEK. Besides, there could be a gain of 185,000 SEK from yet unpaid carbon credits, which could be shared between the farm and the biogas plant. In addition, the biogas-system also results in a 218.4 t reduction of CO<sub>2</sub> eq. emission. Therefore, if all milk-recorded cows in Sweden were considered to be part of the biogas system, it theoretically will imply a 27 % reduction in GHG emissions from the use of agricultural machinery. Results thus established that adopting the biogas-based system will not only result in cost-neutral to farmers, but also a considerable reduction in methane emissions.</div></div><div><h3>SIGNIFICANCE</h3><div>The paper provides a joint farm-level economic and climate assessment of transition from conventional dairy farm to a biogas system, highlighting potential trade-offs and synergies between the two outcomes. Our result offers valuable understanding about how market internalisation of fossil-free transition in dairy farming can happen through the creation of economic and business incentives that encourage trading between farmers and biogas plants.</div></div>","PeriodicalId":7730,"journal":{"name":"Agricultural Systems","volume":"228 ","pages":"Article 104358"},"PeriodicalIF":6.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143907096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
