When Youth Draw What Matters: Native Crops, Climate Change, and Connection

You can feel the shift.

The rains do not come when they used to.
Crops wither.
Pests like the Andean weevil thrive.

In the highlands of Cotopaxi, climate change is not a theory, it is a lived reality. Families rely on farming, and when the land suffers, so do livelihoods, traditions, and entire ways of life.

Ask the youth what they know about potato agrobiodiversity, and most will mention “Super Chola”, a common variety grown for market. But varieties like Coneja Negra or Leona Negra, both known for surviving droughts, often draw blank stares. Mashua, another native Andean tuber with pest-repelling properties, is rarely seen as food anymore. It is remembered mostly for its medicinal use, if at all.

That is the gap this capacity-strengthening event set out to bridge.

In collaboration with the University San Francisco de Quito (USFQ), the Technical University of Cotopaxi, EkoRural Foundation, the INIAP (the National Agriculture Research Center), and the International Potato Center (CIP), a scientific illustration course was launched, not just to teach drawing, but to reconnect youth with their agrobiodiversity heritage and raise awareness of climate resilience. This was done under the project “Andean Crop Diversity for Climate Change” supported by Global Centre on Biodiversity for Climate (GCBC), and the University San Francisco de Quito.

Eleven youth from rural communities and nearby universities joined the five-session course. Three sessions were held in person and the rest were online. Participants visited University San Francisco to learn the principle of botanical illustration: detailed observation and drawing. Drawing nature requires a deep observation of different subjects and breaking paradigms to “draw what we actually see” in place draw what “we have been thought to see”. This is a deep reflection process that makes us appreciate the rich details of nature.

Students also visited the USFQ Herbarium where they learned how plants are documented and preserved and saw firsthand that some native crops are barely represented – even in scientific records. Later, the Technical University of Cotopaxi hosted sessions where participants worked mainly on how to mix colour to capture the details of samples of native potatoes and mashua provided by the International Potato Center.

Some participants chose to illustrate Chaucha Roja, a native potato variety known for surviving even in difficult seasons. One participant shared:

“Chaucha Roja faces many challenges like drought, but it stays resilient to climate change and continues to produce.”

Others focused on other native potatoes after speaking with grandparents who remembered planting them but had stopped due to the labour and pest issues:

“What my grandmother told me is that they used to plant it, but not anymore, because it requires more care and there are more pests. Still, it is a crop that is more resistant to drought… so it could really help with climate change.”

Some insights were straightforward but powerful:

“Yes, it helped us. During the drought season, it held up well with compost. So yes, it helped me for food.” (Referring to the potato)

The resulting illustrations were not just botanical, they were cultural and ecological. Each one carried a story, a memory, and a perspective on how these native crops can support adaptation in a changing climate.

To celebrate these efforts, the youth’s work was exhibited along the work of 19 artists, from 18th to 25th May at QGalery from the San Francisco de Quito University and the Botanical Garden in Quito. This exhibition was part of a global event: Wordwide Bontanical Art 2025, to showcase this discipline across the world. The exhibition placed local crop diversity at the centre, through the eyes and hands of the youth who are reclaiming it.

 

Reflections from the Process

This experience left us with several powerful takeaways:

  • Youth need space to explore. When given the time and tools to connect with their own cultural and ecological heritage, they do not just participate, they take ownership.
  • Dialogue creates change. Conversations with parents and grandparents sparked not just knowledge sharing, but pride in crops and practices that had been overlooked or forgotten.
  • Context matters. Young people do not talk about climate change the same way scientists do, but they understand it deeply through their lived experience. Letting them express that through art made it real, personal, and lasting.
  • Art renews connection with nature: The simple process of observation and drawing creates a powerful link between the artist, the observer and the subject. It helps us to question us about the nature that surrounds us and makes us remember how our lives are linked to nature.

 

This capacity-strengthening event reminded us that young people are not just future leaders. They are current voices. And when they are invited into the conversation with respect and creativity, they draw more than just plants.

They draw connections.
They draw awareness.
They draw change.

Towards COP30: Belém Workshop Explores Forest Restoration in Pará

On 10 June 2025, the city of Belém hosted a key event on the future of forest restoration in the state of Pará. The workshop “Towards COP30 – Integrated and Participatory Planning for Forest Restoration in Response to the Climate Crisis” took place at Embrapa Amazônia Oriental.

Organised by Lancaster University, UK and Embrapa Amazônia Oriental, the workshop was part of the international research project “Enabling Large-scale and Climate-resilient Forest Restoration in the Eastern Amazon,” funded by GCBC and the Centre for Advanced Socioecological Research for Environmental Recovery (CAPOEIRA).

The milestone event brought together scientists, restoration practitioners, policymakers, and civil society organisations to spark dialogue, strengthen collaboration, and help steer forest restoration efforts through the Embrapa–Lancaster University partnership.

Joice introduced both projects (GCBC and Capoeira) and outlined the day’s agenda. 3) Andrea Coelho (SEMAS-PA) presented perspectives from Pará State’s restoration strategy.

The event was attended by representatives from Pará State Secretariat for Environment and Sustainability (SEMAS), Museu Paraense Emílio Goeldi (MPEG), Federal University of Pará (UFPA), National Institute for Space Research (INPE), Amazon Institute of People and the Environment (Imazon), Luiz de Queiroz College of Agriculture (ESALQ/USP), International Institute for Sustainability (IIS), WRI Brazil, Socioenvironmental Institute (ISA), and the Amazon Restoration Alliance, among others.

Dr Joice Ferreira, co-founder of the Sustainable Amazon Network, highlighted that the event built on earlier co-construction efforts under the State Plan for Native Vegetation Recovery (PRVN), where Embrapa has played an active role.

“We’re now turning our attention to the spatial planning side of restoration,” she explained. “Our research is focused on identifying where restoration efforts can deliver the greatest impact—boosting climate action, enhancing biodiversity, and addressing critical challenges like water scarcity and food security.”

Professor Jos Barlow, Principle Investigator from the Lancaster Environment Centre, emphasized that the longstanding collaboration with Embrapa, and strong partnerships with Brazilian institutions, has been key to bridging restoration and forest conservation efforts. “Through this workshop,” he noted, “our goal was to sharpen the focus of our research, ensuring it responds directly to local challenges and supports practical, place-based solutions.”

 

Pará Aligns with Global Commitments

Pará currently has around 23.2 million hectares of open areas lacking native vegetation cover, equivalent to 18.6% of its territory. These environmental liabilities are concentrated in private lands (12.8 million ha), rural settlements (5 million ha), Indigenous territories (424,000 ha), quilombola territories (337,000 ha), protected areas (1.6 million ha), and undesignated public forests (2.9 million ha).

Many of these areas are used for low-productivity pasture and agriculture, especially in the eastern and southeastern parts of the state. On private lands alone, 2.88 million hectares are legally required to be restored under the Brazilian Forest Code, including Legal Reserves (RLs) and Permanent Protection Areas (APPs).

As a major South American country facing complex land-use challenges, Brazil has committed to restoring 12 million hectares by 2030, in line with international frameworks such as the Paris Agreement, the New York Declaration on Forests, and the Latin American 20×20 Initiative. For Pará, connecting to this global goal and restoring part of its environmental liabilities is both a legal obligation and a strategic move to reduce deforestation, recover ecosystem services, and promote a forest-based economy.

According to Andrea Coelho, Cabinet Advisor at the Secretaria de Meio Ambiente, Clima E Sustentabilidade (SEMAS), forest restoration in the Amazon requires a holistic, multi-scalar approach. “This is why coordination among public institutions, the productive sector, local communities, academia and civil society is so critical. Such collaboration allows for harmonisation of data, methodologies and capacities, and alignment of policies, funding programmes and on-the-ground efforts.”

Andrea added that this collaboration also strengthens governance and supports joint restoration efforts aligned with shared goals such as climate neutrality, biodiversity conservation and social inclusion. “It also improves resource allocation efficiency and avoids duplication, ensuring that restoration plans are grounded in technical evidence, social legitimacy, and territorial feasibility.”

Bringing together government, civil society, academia and local organisations is essential to ensuring that restoration strategies are not only scientifically sound but also socially legitimate and practically viable. No single institution has all the answers. Building integrated solutions requires bridges, exactly what this event set out to create.

Dr Leonardo De Sousa Miranda, University of Lancaster

 

COP30: An Opportunity

The workshop offered a vital opportunity to reflect on how Pará’s restoration efforts can align with global climate strategies, especially in the lead-up to COP30, taking place in Belém in November 2025. The event also strengthened the state’s spatial restoration planning and helped identify collaborative actions that could be showcased during the global climate summit.

Dr Leonardo de Sousa Miranda, researcher at Lancaster University and part of the organising committee, said the workshop came at a historic moment for Brazil, and especially for the Amazon, by offering a platform to highlight concrete examples of environmental leadership.

He stressed that large-scale restoration in the Amazon requires coordinated efforts among institutions with different roles and expertise. “Bringing together government, civil society, academia and local organisations is essential to ensuring that restoration strategies are not only scientifically sound but also socially legitimate and practically viable. No single institution has all the answers. Building integrated solutions requires bridges, exactly what this event set out to create.”

According to Leonardo, the approach goes beyond simply sharing data. “It’s about co-creating knowledge. We want to build together; listening to and learning from forest peoples, smallholder farmers, and restoration practitioners,” he added.

 

Programme Highlights

During the event, participants explored key themes such as restoration planning in Pará; key metrics and indicators for a multi-benefit restoration strategy beyond carbon; the incorporation of climate risks, such as drought and fire; and how to ensure genuine participation of producers, communities, technical experts, and public managers.

To foster these discussions, the workshop featured preliminary findings from collaborative projects that are mapping restoration opportunities, challenges, and pathways across Pará.

“This was a crucial step toward strengthening the technical, social, and political foundations for a more resilient Pará—one that is aligned with global climate goals,” concluded Joice Ferreira.

As the region moves toward COP30, the insights and alliances forged here mark an important milestone in the building of a more sustainable and inclusive restoration agenda for the Eastern Amazon.

 

Introducing CROSSROADS: Using native plants to restore biodegraded soils in Ethiopia

The first in-person meeting of the CROSSROADS project was held between 10 and 14th March, 2025 in Hawassa, Ethiopia. CROSSROADS is one of the new projects awarded last year under the GCBC’s Second Research Grant Competition (RGC2).

Researchers from lead partner, the University of Aberdeen (Scotland), and the International Water Management Institute (Addis Ababa, Ethiopia), travelled to Hawassa to meet partners from the Central Ethiopian Agricultural Research Institute and Hawassa University.

A healthy soil is the basis for improved rural livelihoods and resilience to climate change. Using side-lined plant species to improve soils could increase their value and so encourage their spread. CROSSROADS aims to catalogue and rate side-lined species with potential to restore agriculturally degraded soils. This will use a combination of systematic review of the existing scientific literature, community engagement to draw together traditional knowledge, new field and lab measurements, and modelling.

A major component of the project is the development of new tools to communicate findings, dissemination of tools and facilitation of use of top-rated species.

Fighting soil erosion with innovation

A visit to potential field sites in the area of Lokka Abaya, South of Hawassa, highlighted the limitations on organic inputs available to improve the soil; a high proportion of crop residues are used for livestock feed, fuel or building. Land pressures reduce the amount of space available for wild species to proliferate, resulting in high potential for biodiversity loss. Many of these wild species could be used to improve soils by adding or releasing nutrients, or by stabilising the soil with their roots to reduce erosion.

Exclosure areas that could be used as sources of seeds for restoration of degraded soils

The CROSSROADS team visited an exclosure area in the kebele (the smallest administrative unit in Ethiopia). Exclosures are formerly degraded areas where livestock and cropping have been excluded to allow time for the fertility of the land to recover. An important idea to emerge from this visit was the potential to encourage the top-rated side-lined species to grow in exclosures, providing a source of seeds for plants, which could then be collected by local entrepreneurs and used for soil improvement.

In research aligned to the GCBC CROSSROADS project, University of Aberdeen and Hawassa University researchers worked together to construct a laboratory rainfall simulator at Hawassa University. This new equipment allows for controlled testing of soil erosion, providing detailed information on soil loss and water flow under rainfall conditions typical of the regions we are exploring. Livestock, especially grazing in communal grazing areas, are responsible for high levels of erosion. We are using the rainfall simulator to evaluate how biodiverse plants and different types of land management can combat soil erosion, arguably the greatest threat to agriculture in sub-Saharan Africa.

A rainfall nozzle and pressure controllers were brought from the UK; these match equipment already in place in the laboratory at the University of Aberdeen. In Ethiopia we scoured markets to buy consumables and worked with local tradespeople to construct a 4 m tower from bamboo with metal erosion troughs to hold soil during testing.  Delivering water to the rainfall simulator required a water supply to be diverted to a large holding tank, which is then pumped at controlled pressure to regulate rainfall intensity.

Early results have found improved stabilisation in soils collected near to homesteads (where more biodiverse plants are grown) compared to soils from further away (where fields are planted with monocultures). With this equipment now in place, there are many opportunities to explore the impacts of specific plants or biodiverse mixtures, with the objective of demonstrating how side-lined plant species could help combat erosion by improving soils. By using underutilised plant species, both above and below-ground, biodiversity will be enhanced through increased use of indigenous crops, trees and shrubs to improve fertility and reinforce unstable soils. The extent of this and the consequent impacts on soils, biodiversity, poverty and climate adaptation will be fully quantified and understood through the CROSSROADS project.

 

 

 

 

 

 

TerraViva Sustainable Landscape Approach (TerraViva project)

Gaitania, a coffee-growing community of the municipality of Planadas in the southern Tolima department of Colombia, is marked by several challenges: a prevailing monocropping production system for washed Arabica coffee, unsustainable agricultural practices, a complex history of social armed conflict, and a lack of access to markets. The absence of a landscape approach also makes decisions regarding biodiversity, climate change, and livelihoods a farm-by-farm issue at the will of each producer.

This project aims to foster a sustainable landscape approach in a post-conflict region. With initial GCBC R&D funding, the Sustainable Agriculture Network (SAN) and its partners sought to understand the situational context of the Gaitania region and the interactions of governance structures, communities, and socio-economic factors with the interconnected patchwork of different land uses, ecosystems, and land cover. Research entailed mapping all relevant stakeholders that play a role in the landscape and interviewing them at length. This includes political actors, farmer organisations and cooperatives, the local environmental regulator agency, and smallholder producers from the villages which are represented by essential governance bodies called Community Action Boards. Representatives from these communities also took part in workshops where the TerraViva consortium deployed a Community Capitals Framework (CCF) research approach which allowed the consortium to view the various elements, resources, and relationships within a community from a systems perspective.

The CCF focused mainly on the assets of a community rather than on community needs and deficits. It divides a communities’ assets into natural, human, social, cultural, built, financial, and political capitals and focuses on the interaction among the seven capitals and the resulting impacts across them. Guiding questions helped the community take an appreciative approach to analyse the various capitals and how they could be leveraged to strengthen or generate more assets. Additional efforts to understand the context of Gaitania’s coffee production included the mapping of the coffee value chain, drone-assisted cartography, and desk research using secondary data sources. A study to determine the applicability of a payment for ecosystem services model in the context of the Colombian regulations and institutions was also carried out.

Positive Impacts

Culminating with a participatory multi-stakeholder dialogue, the research results will lead to the creation of a Common Territorial Agenda – a long-term development vision built from the perspective of local stakeholders to enable innovative, systemic interventions by balancing environmental, social, and economic goals of the region’s stakeholders. However, the exploratory process itself has already yielded positive impacts with the community. The differentiated approach taken to build solutions – by recognising the community’s preponderant role in the decision making to build the Common Territorial Agenda – opened spaces for smallholder producers to think broadly and collectively about the state and future of their landscape.

The CCF workshops also raised local awareness of the opportunitiesthat Gaitania’s many assets present for the community’s development and of the negative environmental and social impacts of coffee farming and production caused by the current practices implemented by smallholder farmers. Further impacts will occur once the Common Territorial Agenda is implemented and will be measurable in the long term. 

Challenges

Transportation was the greatest challenge faced during the implementation of the research project due the distances from Gaitania to the main population center of Planadas and each of the villages. Difficulties were compounded by the poor state of the roads and variable weather. Travelling by day and having a local informant that could report on the weather conditions were important mitigating factors to address these challenges. Given the history of armed conflict in the area, additional safety measures were implemented, however, safety issues were not present during the work performed in situ. Maintaining constant contact with Community Action Board presidents to monitor potential safety issues was also important.

The project encountered participation challenges by two of the six villages targeted to take part in the pilot project. The lack of participation was largely owed to post-conflict recovery and peacebuilding efforts that included many unsuccessful international cooperation pilot projects that lacked sustainability and impactful results. Identifying the community capitals using the CCF was an important approach to differentiate this project and help with future plans. Maintaining a strong local presence in the Gaitania was also an important way to build rapport and trust with locals and community leaders.

Lessons learnt and next steps

This research project was designed to be replicable in many productive landscapes and tested in a complex region like Gaitania precisely to increase its replicability. As landscapes are social constructs, building trust with the targeted community is pivotal to ensure continued and active community engagement. This demands local presence, constant communication with community leaders, transparency during the process, and communication of results. Understanding the local context is also a critical factor for project success.

In a community like Gaitania, historical complexities can interfere with the technical aspects of project implementation. Therefore, social awareness and sensibility are necessary for productive and respectful interactions between field staff and community members.

Co-owning the One Food principle with the South African government (One Food project)

The One Food project seeks to develop a Food Risk Tool to assess and mitigate multiple hazards across the entire food system and to transform the way actors (governments, researchers, industry, third sector) perceive and work on food production to ensure economic, environmental, and social sustainability. Since such a transition is impossible without full buy-in from partner country policymakers, the project worked to secure South African government co-ownership of the concept.

This was achieved by targeted engagement with government departments through a series of scoping, workshops, and follow-up engagements. The project also supported in-country research and capacity development to expand the research on tools to assess the hazards present across food systems, linking multiple food sectors (e.g., farming, fishing, aquaculture, hunting) and multiple hazards (e.g., food safety hazards, pollution hazards, biodiversity hazards, climate hazards). This was done through a South African research fellowship scheme designed to support 8 postdoctoral fellows and up to 14 MSc studentships.

Positive Impacts

The South African Government Department of Science and Innovation (DSI), the Council for Scientific and Industrial Research (CSIR), and the Agricultural Research Council (ARC) have agreed to co-fund elements of the project. They are employing a coordinator and are considering allocating a full-time staff member to lead the project concept from the South African side. The departments are also championing the project in internal fora, leading upcoming workshops, and working with the UK project team to identify a second country to expand the concept to. DSI and ARCH have also fully endorsed the scheme and have agreed to ‘own’ and co-fund the fellowships. CSIR has agreed to oversee the scheme and to fund a scheme coordinator.

Challenges

Since One Food is such a broad project, there were challenges with navigating South African government departments to identify the best suited agency to take a lead and then to ensure other government departments remained engaged with the project. These challenges are overcome by having a strong stakeholder strategy informed by local expertise, a dedicated project engagement workshop at the inception phase, and a dedicated UK engagement lead to manage the diverse stakeholders and their needs.

The research fellowship scheme required negotiation with government departments and research councils with different priorities and personnel rules. This presented challenges in gaining agreement on the details of the fellowships and the employment and inclusivity processes that should be applied. The project is overcoming these by drawing on advice from stakeholders familiar with the South African government landscape (particularly from Foreign, Commonwealth & Development Office) and by developing pragmatic solutions to meet the requirements of the different actors and to accommodate South African government priorities.

Lessons learnt and next steps

This intervention has demonstrated that these types of projects are best led by UK Government departments rather than academia or NGOs. This results in more traction within overseas Governments which, with support from the local FCDO’s Science Innovation Network and other global initiatives that are already linked to a government (e.g., United Nations Environment Programme, Food and Agriculture Organization, etc.), leads to higher engagement and likelihood of successful delivery with partner countries.

The research fellowship scheme is an excellent way to support career development in collaborating countries and particularly to support under-represented groups. It is important to understand the scientific and research context to ensure fellowships are pitched at a useful level (undergraduate, graduate, or postdoctoral level) and understand how the fellowships might help future career opportunities. Diplomacy and compromise are key.

Realising the potential of plants as nature-based solutions in African biodiversity hotspots: Supporting climate resilient, sustainable development (Kew TIPAs project)

High biodiversity developing countries face numerous competing pressures surrounding poverty and food insecurity. Conservation can support sustainable development while improving lives and livelihoods. Kew’s research and conservation activities in Ethiopia, Guinea, and Sierra Leone focus on identifying and evidencing the value of high plant biodiversity landscapes to communities and their governments. This project supported capacity building on Red List conservation assessments, herbarium skills, and conservation research through a 2-month internship programme at Kew for 11 early-career scientists and a 1-week Ethiopian Red List training workshop for 16 participants.

Community outreach programmes, such as the Guinean Schools programme that reached 100 children from 10 schools and the Guinean Community Awareness training programme that involved over 500 villagers, raised awareness of the importance of conservation and sustainable use of biodiversity. The establishment of 5 plant nurseries involved 88 members of 4 local communities adjacent to two newly established Tropical Important Plant Areas (TIPAS) sites in Guinea, helping to incentivise locals to manage and maintain reforestation projects adjacent to the TIPAs sites. The unifying purpose of these activities was to build in-country capacity to lead future plant conservation strategy, planning, and practice particularly in the context of Kew’s TIPAs programme and the new Global Biodiversity Framework targets.

Positive Impacts

The capacity building activities focused on training mainly women and girls (17 out of 27) on a wide range of skills that are expected to have a positive impact on their careers. Following completion of the first project phase, newly trained assessors in Ethiopia and Sierra Leone will lead the assessment of parts of the remaining unassessed endemic species in the current project phase. . There has been a high level of engagement with the installation of nurseries and seed collection for forest trees. School teachers and students also benefited from the awareness training. Posters of threatened tree species have been produced and translated into local languages.

There are plans to establish school clubs with gardens to increase awareness of threatened trees and improve the surrounding environments. Lastly, one of the nurseries has grown c. 2,500 saplings of threatened and useful plant species for community livelihoods and reforestation in the buffer zones of two TIPAs sites. Communities have formed and signed a one-year agreements with the forestry service to produce and maintain the nurseries which are expected to produce a minimum of 1,000 plants for use in assisted regeneration of the forest in these areas with long-term benefits to the local communities.

Challenges

Generally, the lack of continued funding and adequate resources makes it difficult to provide the long-term support and partnership for true capacity building activities. However, the project benefited from Kew’s >30-year track record in countries such as Ethiopia and the strong, trusted relationships developed over that time. There were also issues related to securing visas for early career developing country researchers. During the awareness training in Guinea the main challenge encountered was access to the villages during the rainy season and the low level of education. This was overcome by significantly modifying the material to be more accessible. For the nurseries, the main challenges arose from aquiring enough seed of threatened species and propagating them successfully since few of these species have been propagated before. To overcome this, data is being collected on the techniques used for future propagation protocols.

Lessons learnt and next steps

Key to successful implementation is long-term partnership with host countries beyond the activity of a single grant. Attendance of the training workshop followed by participation in the internship programme was a very successful combination that allowed project interns to refine their skills and start contributing to project assessment outputs and deliverables with almost immediate effect.

Awareness training in both communities and schools can easily be replicated and will be continued at communities in the TIPAs sites of Mt Béro and Diécké. The use of visual materials, translation into local languages, and participatory approaches are essential for good understanding by the communities. The approach followed to establish the nurseries is a simple and effective intervention but necessitates community involvement. Continued awareness training on the importance and benefits of biodiversity and the wider environment is necessary to ensure successful implementation.

Developing novel seaweed cultivars from wild populations (Innovative Seaweed Aquaculture project ASTEC)

Seaweeds form some of the most productive systems in the marine environment. They support an immense diversity of species, provide valuable ecosystem services, and play an important role in mitigating climate change as major carbon sinks. Seaweed cultivation offers the potential for a nature-based, carbon neutral, and climate resilient solution to restore seaweed communities globally. Upscaling seaweed production offers a new, powerful approach to enhance community resilience, re-build natural seaweed communities, increase biodiversity, and enhance ecosystem services. It can also provide a socially acceptable means of restoring a communities’ local environment whilst maintaining economically sustainable livelihoods.

Eucheumatoids are tropical red seaweeds frequently used in the food and cosmetics industries. Increases in pest and disease outbreaks due to accelerating climate change, loss of genetic diversity, and biosecurity issues have led to seaweed production in Malaysia declining by 45% between 2012 and 2020, with catastrophic socio-economic impacts on the communities reliant on seaweed production. To address these challenges, there is an urgent need for new temperature-resilient cultivars derived from indigenous wild stocks, which can enhance the climate resilience of cultured stocks.

Positive Impacts

This project works with indigenous seaweed farming communities in Malaysia to collect populations from the wild for domestication trials at a research farm in Sabah. This has resulted in the discovery of new temperature-resilient cultivars that are brought into cultivation to enhance the climate resilience of cultured stocks in Malaysia. This is crucial to ensure the sustainability of the eucheumatoid industry despite the global climate change issues.

Challenges

The major challenge during the project was the impact of the water currents on farmed seaweeds. The conventional method of tying the seaweeds onto the cultivation lines using plastic ties (called ‘tie-ties’) led to high levels of seaweed loss from the lines and increased fish and turtle predation. Consequently, growth rates could not to be measured. To solve this problem, the wild eucheumatoids were placed into the nylon nets. Unfortunately, this method also proved ineffective as silt from the seabed covered the nets and smothered the seaweeds.

Following discussions with the local farmers, new baskets were deployed with a larger mesh-size to prevent the entrapment of silt. The eucheumatoids were placed into the new nets for 2-3 weeks to enable sufficient growth before tying onto the cultivation lines. This solved the problem and reduced the effects of fish and turtle predation.

Lessons learnt and next steps

The outcome of this project was to develop new temperature-resilient cultivars that can be used by seaweed farmers in Malaysia. A system was developed for coastal seaweed cultivation of new cultivars that can be replicated throughout Malaysia. Site selection, however, was found to be extremely important, particularly the levels of siltation in the water column, which can suppress eucheumatoid growth rates.

 

 

 

Waste not, want not: Investing the use of disposable nappies and black wattle biochar for land rehabilitation in the upper uMkhomazi River Catchment (Environmental Pollution programme)

Residents in communal lands in the upper uMkhomazi River Catchment, in the KwaZulu-Natal Province, South Africa, do not have access to waste collection services. This results in the rise of improper and indiscriminate waste disposal including disposable nappies thrown away from the homestead, often in water courses, posing potential health and environmental risks. Faecal matter in nappies can contain pathogens and potential toxins. However, they are also a source of nutrients – particularly nitrogen, phosphorus, and potassium – that can be used for agricultural purposes. Burying nappies can enhance soil water holding capacity (through superabsorbent polymers (SAPs) contained in disposable nappies) and improve soil nutrient supply. Therefore, they can help rehabilitate degraded and nutrient-poor soils.

In the upper uMkhomazi Catchment there are ~7,500 ha of abandoned cultivated lands which have become degraded due to erosion and bush encroachment by black wattle (Acacia mearnsii). Clearing these trees/bushes could improve the ecosystem health and converting the wood to biochar can provide a source of carbon to improve soil biological processes and restore degraded soils.

This project aims to assess the utility of simple, low cost, and culturally acceptable options for the use of disposable nappies and biochar from black wattle, both individually and in combination, as in-field soil amendment media in degraded and abandoned agricultural lands at selected sites in the upper uMkhomazi Catchment. The initial experiments included two species of fodder plants (Napier Fodder and Vetiver Grass) and will be monitored over a period of two years (i.e., two growing seasons under rainfed conditions) with measurements of biomass yield, sediment capture, soil biological indicators, soil fertility, soil chemistry, soil water, pollution, and pathogens.

Positive impacts

This is the first year of a 3-year programme. Although too early to fully determine and measure the impacts, preliminary measurements suggest that treatments that included fertiliser show greater crop growth.

Challenges

A hot, dry spell delayed the monitoring of the vetiver grass component of the trials for the first growing season. The team planted replacement tillers and provided temporary irrigation to assist with propagation. The dry spell is likely a consequence of climate change, and more frequent and erratic dry or wet climate events could be expected in the future.

Lessons learnt and next steps

Results from the first growing season show that this type of intervention yields positive outcomes. However, longer-term monitoring from multiple growing seasons will be needed to determine the full impact on the soil and plant growth and subsequent replicability.

 

Demonstrating the value of drones and remote sensing to a rural community in the Philippines (Bio+Mine project)

One of the key questions for management of legacy mines is to find an affordable way to monitor abandoned sites. Remote sensing provides both active and passive sensing technologies; however, a large skills gap lies between remote sensing technology and the ability to apply it locally. Nearly 40 years of analysed satellite imagery indicates that the Santo Niño site, in the Philippines, has not yet recovered to pre-mining conditions. Though the site shows improvements through time, the resolution of the satellite data is not high enough to assess how local biodiversity has evolved. Drones and associated imaging technologies can deliver centimeter-scale resolution images, solving this issue.

An aim of the Bio+Mine project is to carry out repeated high-resolution multi-drone survey of the entire study site to: i) provide spatio-temporal context to support the interpretation of the other in-situ measurements, ii) collect high-resolution data to inform the decadal results from satellite data, and iii) showcase how drone technology and machine learning can be used to manage natural resources efficiently.

Positive impacts

This project used two drone systems operated by trained graduate and undergraduate students supported by research assistants from the Philippines. Two full site surveys were performed and data delivered a new 3D digital elevation model for the area, providing a baseline for future land stability assessments. Drones also proved to be excellent tools for community outreach, attracting curiosity and engagement with the local population as well as local authorities.

Challenges

The main challenges involved international air travel with drones (including lithium battery transport), difficulty complying with drone flying regulations, and the lack of active signals from the Continuously Operating Reference Stations network in the Philippines. Moreover, deploying drones efficiently and safely in mountainous terrain over vast areas was challenging and required experience.

Lessons learnt and next steps

Going forward, the project aims to train and enroll local partners to fly drones and support the creation of a survey startup. The cost of acquiring new drones limits local engagement. However, work has already begun in partnership with AminoLab, the innovation branch of Dela Salle University, to develop a 2.5 million PHP (~£60,000) entrepreneurship programme capable of supporting approximately ten companies.
