Summary: This article examines the formalization process and governance of artisanal and small-scale sand mining in the Dar es Salaam Region of Tanzania. It analyzes the key aspects and rationales of formalization by interviewing various stakeholders, explores the perception of formalization in the sand commodity chain and community, and assesses the environmental impacts of sand mining. Given the rapid growth of sand extraction in Sub-Saharan Africa, policymakers should pay attention to the governance efforts in the Dar Es Salaam area and prioritize the formalization of artisanal mining.

Summary: This paper argues that the impact of land formalization projects on the quality of urban housing in developing country cities has been generally disappointing. The lack of attention to contextual features of land markets in project design is identified as a key factor. Evidence from a case study in Dar es Salaam, Tanzania suggests that households may not value formal property rights in cities where broader property rights institutions are incomplete and informal sources of tenure security are strong.

Summary: With the rapid increase in world population, urbanization and food insecurity have become major concerns. In response, food synergies between towns are being pursued, especially in the Global South to address food problems. A study focused on vegetable production and supply dynamics in Dar es Salaam and Morogoro found that the two cities are highly dependent on each other. Dar es Salaam relies on both nearby and distant cities for food supplies, while Morogoro is the main supplier of vegetables to the city. However, both cities face the challenge of inadequate storage facilities for farmers and buyers.

Summary: This paper explores the persistence of urban master planning in African cities. It shifts the focus from critiques of master planning in Africa to the role of local planning actors and proposes a new analytical perspective. Through three case studies, the paper demonstrates the continuous presence of master planning practices and their proliferation in contemporary moments. The analysis highlights the influence of both local and transnational actors in shaping master plans.

Summary: Uncontrolled urban expansion driven by rapid population growth puts enormous pressure on urban environment. This study takes Dar es Salaam, the largest city in Tanzania, as a case study and uses multi-source data to obtain annual urban impervious surface component data. Based on this data, the spatial-temporal characteristics of urban expansion are concluded: firstly, the expansion shows phased patterns with an annual growth rate of 2.9% during 2000-2005, 1.4% during 2006-2010, and 3.3% during 2011-2019. Secondly, expansion hotspots emerge along main roads extending from the city center to the south and north, with coastal expansion and infilling development becoming evident after 2015. Thirdly, urban land expansion lags significantly behind population growth, with a declining ratio of population growth rate to land expansion from 2.9 during 2002-2012 to 2.0 during 2012-2019. Finally, the influence of population, economy, traffic, and nature on impervious surface evolution is analyzed, and corresponding strategic suggestions for land-use policies are proposed along with the analysis of future trends in urban growth spatiotemporal patterns.

Summary: The study examines how residents in Sub-Saharan African cities at the urban periphery self-supply and collect water through ordinary means, and how these practices shape water access. While ordinary ways hold potential for addressing water access gaps, they are limited by uneven power relations, propertisation and commodification of water infrastructures.

Summary: The study conducted in five mangrove ecosystems in Tanzania revealed anthropogenic nitrogen pollution, with varying degrees of pollution indicated by different nitrogen isotope values. The enrichment of 815N values suggests that polluted sites may receive high loads of domestic sewage from surrounding communities, industries, and agriculture. Proper waste and wastewater management upstream are recommended to protect mangrove ecosystems.

Summary: Despite the advantages of modern and clean cooking energy, the adoption rate in Tanzania is very low due to a preference for a mix of dirty and clean energy rather than purely clean energy. The study found that the transition from dirty energy to clean energy is a longer process, as it is only affordable for a small minority of high-income individuals. This results in the majority of poor people being trapped in the use of dirty energy, despite the growing market for liquefied petroleum gas (LPG). To address this issue, policy options include either improving income levels to accelerate the transition or implementing wider electrification measures with appliance subsidies or microfinance to make clean energy more affordable.

Summary: Decision-makers, planners, and administrators face the challenge of fostering balanced, sustainable, and territorially integrated development. The role of spatial planning in improving relations between rural, peri-urban, and urban areas is examined, highlighting the need for transparent, participatory governance arrangements that support synergies between different actors and activities. Further research is needed to address these issues and promote sustainable and territorially integrated development in European policy making.

Summary: This paper utilizes the concept of 'sustainable innovation journeys' to track how urban food initiatives influence city-region food policy. Evaluating the success or failure of designs and monitoring stakeholder interactions reveals the transformative potential of innovative projects. The importance of 'soft change' and the alignment of interests between micro and meso levels are highlighted through case studies conducted in Rotterdam, Vigo, and Zurich.

Summary: Wheat can be stored for a longer time and processed into various foods, while potato has a limited storage time. Processing benefits growers by regulating markets and prices, and processors compensate for the decrease in fresh tuber consumers. Large processing companies advocate sustainability measures, improve factory processes, introduce new products, and support communities. The industry faces various issues such as politics, economy, and law, which fluctuate based on raw material base, competition, and consumer culture.

Summary: This study focuses on the processing potato ontology, which includes the domains of growers, processors, and cooks. The history of preparing meals with potato as ingredients dates back to the domestication of the crop. The potato processing industry expanded globally since the Columbian Exchange. The study analyzes the domains through a four-tier approach, including description and delimitation, allocation of classes and attributes, evaluation of attribute values, and clustering analysis.

Summary: In supermarkets in the Netherlands, there are over 150 potato products displayed. These products can be distinguished based on various characteristics such as heating method, appearance, dehydration, and storage temperature. Fancier products require more processes and operations in factories and are more expensive. Consumers value low prices and a wide range of products, tastes, and sizes, while processors prioritize other attributes. The different operations in factories include dehydration, heating, cooling, and transformation. Heatmapping and hierarchical clustering were used to analyze the products and their attributes. In total, there are 66 operations involved in the processing of potatoes. Potato processing is different from wheat processing due to the larger range of operations and storage conditions.
