Contributions of Urban Collective Gardens to Local Sustainability in Mexico City

Promoting Urban Agriculture and Its Opportunities and Challenges—A Global Review

Multifunctionality of urban agriculture can support the resolve of many urban challenges. Therefore, it is vital to understand the contribution of academic studies on urban agriculture practices as scientific information. The present study followed a systematic literature review based on the PRISMA method. Finally, 54 identified articles were analyzed. The review study mainly examined the contribution of academic literature on urban agriculture under four dimensions: the socio-economic context of the country, type of agriculture model, opportunities, and challenges. The results revealed the focus of academic literature on urban agriculture to show favoritism toward developed countries’ community gardens. Moreover, the leading academic focus on this discipline identifies multifunctionality. People’s motivations in developed countries tend to favor social, health-related, and educational benefits of urban agriculture; however, in developing countries, urban agriculture is more related to economic and ecological needs. Challenges for urban agriculture are also different among developed and developing countries. Nevertheless, existing academic studies have given comparatively less attention to identifying challenges, benefit groups of urban agriculture, and government support. Since urban agriculture is highly reliant on local factors, studying more about opportunities and challenges for urban agriculture under different socio-economic contexts and different agriculture models could be more beneficial to connect farming practices in cities with urban planning. Therefore, to make an adequate academic contribution to urban sustainability, future urban agriculture studies need to be more holistic.

Overview of Research on Sustainable Agriculture in Developing Countries. The Case of Mexico

One of the principal challenges faced by Mexican agriculture is the development of management models that are able to increase production while respecting the environment and generating wealth for society as a whole. In recent years, the number of studies analysing the sustainability of Mexican agriculture has grown significantly. The purpose of this study is to analyse the evolution of the research on the sustainability of agriculture in Mexico. For this purpose, a review and bibliometric analysis of a sample of 867 articles was carried out. The results reveal that the research has focused on the development of sustainable agricultural models in vulnerable rural areas, the sustainable exploitation of agroforestry systems, the development of energy crops for different uses, water resource management and land uses and their changes, conservation farming and climate change. Although research focused on sustainability is still in its early stages, it has become a priority field. A need to promote research from the economic and social disciplines may be observed, together with holistic projects that include the three pillars of sustainability (social, economic and environmental). This study could be useful to researchers in this field as it identifies the recent trends and principal agents that drive knowledge.

Progress in Research on Sustainable Urban Renewal Since 2000: Library and Visual Analyses

Urban renewal is an ideal approach to promoting the value of the urban fabric and improving the sustainability of the urban environment. This study, which shows the continuity of research on sustainable urban renewal, aimed to identify sustainable urban renewal literature based on a library analysis of scientific research since 2000. A total of 3971 scientific papers from the SCIE (Science Citation Index Expanded) and SSCI (Social Sciences Citation Index) databases were reviewed to examine how research concerning “sustainable urban renewal” has emerged and developed in the past 20 years. The h-indices and impact factors of the most relevant journals in urban renewal and sustainable development since 2000 were analyzed. The most frequently cited articles were analyzed using analysis of social networks (VOSviewer). The results revealed potential future focuses of research and guidelines that link urban renewal and sustainability: the engagement of all stakeholders in the decision-making process; the involvement of residents in projects; the development of cooperation between towns and cities; the preservation and reuse of built and industrial heritage while respecting environmental law; and, finally, the search for new financing techniques. These potential future research topics were analyzed in four research areas so that sustainable development can easily be integrated into an urban renewal project.
