HortaFCUL is a project created and managed by the Faculty of Sciences at the University of Lisbon to raise awareness and promote the practice of permaculture as a solution to the ecological, social, and economic problems the world is facing (1). This initiative began in 2009 on the University campus through a garden, which allowed HortaFCUL to start conducting some activities that could answer some socio-environmental challenges, such as food security and sovereignty, ecosystem degradation and climate change (13), by raising awareness, teaching, and practising many aspects involved in permaculture and urban agriculture (2). Its focus has been on regenerating soil in an urban environment and creating productive landscapes for people and other beings (12). They grow different types of plants (vegetables, shrubs, trees) in different ways (swales, raised beds, greenhouses) to increase plant diversity and foster ecosystems (13).
The project is managed by students and researchers, who hold educational activities, such as courses, workshops, and dissemination activities (events, discussions, fairs, and conferences) (2). The project is organised according to a non-hierarchical sociocratic model, in which all decisions are made as a group, and where all ideas, critiques, and suggestions are seen as added value and an opportunity to improve techniques and knowledge (3). Additionally, it is open to the community, allowing anyone interested to participate and volunteer (1).
HortaFCUL is also one of the pioneering permaculture projects in operation in the Lisbon region and is now recognized as a national reference centre for permaculture (2). Since its inception, HortaFCUL has sought to be a hub that attracts people, organizations, and other initiatives, and it is currently a point of contact between different projects and associations, such as local businesses, educational institutions, and networks (5).

The environmental impact of golf has led to growing calls to make the sport more sustainable (1). Golf course maintenance often involves carbon-intensive fertilizers, frequent mowing, and, in some cases, the clearing of forests or trees that naturally absorb carbon dioxide to make room for expansive fairways (1). However, the Tournament Players Club (TPC) Michigan is working to create courses that benefit both golfers and the environment (2).
Fifteen years ago, the site was a neglected floodplain along the Rouge River, initially purchased by Henry Ford in 1915 and once littered with community waste and old motor parts from the Ford Motor Company (2-3). Today, it has been transformed into an 85.8-hectare course that supports a diverse range of wildlife, including birds, fish, foxes, and coyotes (2). Led by Jack Nicklaus, the restoration aimed to turn this former waste site into an eco-friendly course (2). With guidance from Audubon International, the course was converted into a wildlife sanctuary, becoming the world’s first golf course to receive the prestigious John James Audubon Environmental Steward Award for ecological restoration (2).
TPC Michigan features native Michigan plants, such as viburnums, which produce berries for wildlife, along with various native grasses (2). To prioritize environmental stewardship, the course managers have created buffer zones to protect natural habitats and conserve water by using coring methods to monitor soil moisture (2). Pesticide use is minimized; instead, staff monitor for signs of disease or pests and test the soil to determine the specific nutrients needed for the turf (2). The course’s links-style layout includes rolling fairways, tiered greens, and natural wetlands, with tee options ranging from 5.5 to 6.4 meters (4). By establishing a wildlife sanctuary, TPC Michigan offers golfers a unique experience that fosters a connection with nature (3).

The rate of deforestation in the Brazilian Legal Amazon in 2023 was consolidated at 9,064 km2. Initiatives that promote forest restoration in this biome are emerging to overcome this scenario. One such initiative is Floresta Productiva which aims to reforest more than 200 hectares of degraded land in the southwest of the Brazilian Amazon, known as the ‘arc of deforestation’ (1). Led by the Instituto Socioambiental in partnership with the NGO Rioterra, it focuses on creating and disseminating native forest restoration models that combine ecosystem recovery with income generation for rural producers in Porto Velho (2). By fully integrating local communities, the project promotes traditional agroforestry practices (muvuca) and trains communities to maintain the planted land. This not only restores the forest but also provides economic benefits through the cultivation of timber, fruit trees and other species (2), strengthening sustainable agriculture, breaking the cycle of deforestation and restoring deforested areas through various native species grown in nurseries (1). The project is being developed in the cultivation area of the Amazon Bioeconomy Centre (CBCA), from 2023 to 2025, where it will directly benefit the rural community of Vila Nova de Teotônio (3).
The project started in 2019 and has impacted other communities in the area, such as the communities in Nova Mutum Paraná and Ji-Paraná (1). During these years, more than 123,000 trees have been planted in agroforestry on about 110 hectares of land, and edible forests have been created. Since 2022, a new planting phase has been underway, to plant more than 100,000 trees of 87 native species on 40 hectares of degraded forest (4). In conclusion, this project focuses on the development of agroforestry in the face of widespread monospecific soybean fields and intensive cattle ranching (3); the creation of edible forests (3); and the restoration of forest cover to ensure the long-term resilience of the forest (3).

The project aims to protect seagrass meadows, which are vital habitats for the prey of resident dolphins and essential to the local fishing economy. The initiative involves local fisherwomen, called "Keepers of the Sea," in activities such as marine education, awareness campaigns, and monitoring the health of the seagrass meadows (Ref 1). Founded in 2015, Ocean Alive aligns with several UN Sustainable Development Goals, including ocean conservation, gender equality, quality education, and climate action (Ref 4). The project is supported by partnerships with UNESCO and other organizations, and it extends its efforts to Portuguese-speaking African countries. Ocean Alive’s activities also include advocacy for blue carbon ecosystems and programs that involve community engagement and social innovation (Ref 2, Ref 5).
One of several implementation projects targeted safeguarding the young seagrass meadow at Cambalhão Bay, at the entrance of the Sado estuary, as an Ocean Alive’s initiative in partnership with SeaTrees by Sustainable Surf (Ref. 2). The Cambalhão meadow is made up of 202 patches of seagrass. Unregulated shipping is one of the factors in the degradation of the prairie, and to protect it, Ocean Alive is running a campaign to raise awareness about recreational boating (Ref. 6).

Peru is classified as one of the 17 most biodiverse countries in the world, so biodiversity and its conservation are important national aspects (2, 3, 4). However, one-third of the native flora currently assessed is threatened (3, 4). Thus, the creation of the Botanical Garden represents the opening of a space to learn about, study and conserve the national flora by strengthening Peruvian society's awareness of its value (4, 5).
The Botanical Garden is in its early stages of development and is not open to the public yet, but its development and implementation have the support of several associations such as the British Council, Concytec, the Ministry of Environment, the Ministry of Culture, the British Embassy and the Asociación Pro Jardín Botánico Nacional de Lima (1). The initiative has been incorporated as part of the Bicentennial City project of the Ministry of Environment in Ancon (6).
The implementation began in 2021 on a 10-hectare plot of land donated by the Universidad Nacional Agraria La Molina (UNALM) in Lima (3), and it will be carried out in several stages. An Inter-Institutional Committee has been established to oversee its development (3). In addition, it is planned to extend the idea of botanical gardens to other regions of the country, creating a network that will allow the conservation and study of flora in different contexts (4, 5), as the purpose of its development is to condense in one place all the biological richness of the country (7).
With this project, they aim to strengthen the conservation of plant species, the generation of inputs for education, and as a source of cultural spaces and for the well-being of its citizens, among others (1, 2). The Botanical Garden is intended to house a select sample of the more than 25,000 species in Peru, emphasising those that are endemic, threatened and of social, cultural and economic relevance (8).
