Rangelands cover about half of the Earth’s land surface, store between 10 and 30% of terrestrial carbon, and support over 2 billion people, yet they are under-recognized and under-valued and have been largely ignored in sustainable development agendas and climate negotiations. 

 

Typically, we have our heads in the trees when it comes to thinking about carbon sequestration, as we can see their carbon-storing biomass right in front of our eyes. In a 2022 study of over 6000 peer-reviewed and gray literature, 78% focused on forests while only 6% focused on grasslands and 3% on drylands.

But if we look beneath our feet in rangelands, we can see that they store 70% of their carbon belowground and support 80% of agriculturally productive land, globally, making them a critical focal point for addressing the global challenges of biodiversity loss, land degradation, climate change, water and food insecurity. Restoring degraded rangelands is urgently needed to address these interlinked crises and enhance human well-being.

 

On 21 August 2023, CA4SH joined CIFOR-ICRAF, Focali, IGAD, SIWI, SLU, University of Nairobi, and WWF at the 2023 World Water Week organized by Stockholm International Water Institute (SIWI) in a virtual session to discuss water-smart rangeland restoration.

The theme of this year’s World Water Week was Seeds of Change: Innovative Solutions for a Water-Wise World, facilitating conversations about how we manage water through the nexus of innovation, governance, and science. Moderator Malin Lundberg Ingemarsson (SIWI) opened the joint session by inviting participants to challenge the status quo of under-valuing rangelands in targeted investments for innovation.

Keynote speaker Leigh Ann Winowiecki (CA4SH co-Lead and CIFOR-ICRAF Soil and Land Health Global Research Lead) issued a call to action in advance of the upcoming 2026 Year of Rangelands, stressing that “now is our opportunity to convince the community to come together on rangeland health.” To do this, she underscored the importance of investing in rangeland restoration and rangeland health monitoring, scaling innovations, filling research gaps, and providing scientific evidence to demonstrate the effectiveness of restoration efforts over time. She also highlighted the key role of community engagement and the importance of encouraging farmer and pastoral-led innovations.

Monitoring rangeland health, understanding drivers of land degradation, and tracking restoration progress is entirely within our reach using the innovative Land Degradation Surveillance Framework (LDSF) coupled with Earth Observation (EO) and citizen science. Leigh Winowiecki described the systematic, landscape-level framework which measures a variety of land health indicators including soil infiltration capacity. She shared an example study from the Drylands Transform project in Kenya and Uganda which identified key determinants of water infiltration into the soil, including soil carbon content. Soil infiltration capacity is a critical indicator of land health as it determines the maximum rate at which water can enter the soil, controlling the generation of surface runoff and erosion, which are key drivers of land degradation. Leigh Winowiecki shared that the LDSF is inexpensive and accessible, and called for increased investment in capacity building for farmers and pastoralists to monitor the health of their land and contribute to filling data gaps through citizen science.

 

While the LDSF is a global initiative, case studies showed session participants innovative solutions being implemented in Kenya, Uganda, and Burkina Faso. Margeret Nyaga, PhD student at the Department of Land Resource Management and Agricultural Technology at the University of Nairobi, shared her research within the Drylands Transform project led by the Swedish University of Agricultural Sciences (SLU). Margeret is investigating landscape restoration through Livestock Cafes – knowledge-sharing hubs and experimental sites where the project engages with local communities, extension workers, NGO practitioners, and authorities to test and demonstrate innovative land restoration and water management options – in the Karamoja region between Kenya and Uganda. Water-smart innovations like water harvesting with half moons, rock check dams, vetiver grass planted along contour lines, and reseeding of rangeland grasses and legumes showed evident results after just one year of implementation.

 

Aubin Ouedraogo (Terre Verte) shared the results of promoting Bocage Perimeters (wégoubri in the Mooré language) in Burkina Faso. These are integrated systems with trees, livestock, and crops working together to fight land degradation by controlling livestock grazing and promoting agroecological best practices. The first vocation of the bocage is to keep water where it falls by creating bunds, ponds, and living hedges, in order to mitigate the erosive action of monsoon waters and maintain the biodiversity of the area. Surface runoff is collected in harvesting ponds to recharge groundwater and the bocage perimeters are subdivided into fields that are managed by local families for increased food security.

 

Following the presentations, Margeret Nyaga and Aubin Ouedraogo joined an interactive panel with Dominic Kathiya (IGAD, ICPALD), Melissa D.Ho (WWF-US), and Aida Bargués-Tobella (SLU). Panelists were asked about the role of rangelands in biodiversity conservation and climate, the key aspects of water-smart restoration in rangelands, as well as barriers to upscaling restoration and soil health interventions and the tools we need to do it.

“Grasslands have intrinsic value [but] we forget that half of our land mass is grasslands!”

— Melissa D. Ho (WWF-US)

The panelists echoed the message that rangelands have been overlooked for too long, and that it’s time for a shift in focus when it comes to climate and biodiversity conversations and investments. Melissa D. Ho pointed to the Cerrado savanna in Brazil, neighbor to the Amazon rainforest, which covers 21% of the country’s land cover but which is nowhere near a household name like the Amazon is. Aida BarguĂ©s-Tobella highlighted the dichotomy between water as both a driver of erosion and a source of life and resilience and therefore the cornerstone for restoration in the changing global climate. The key? Healthy soil captures water, making it reliably available for plants to thrive while reducing water-related risks and disasters such as floods and droughts.

 

These points were well-rounded by Dominic Kathiya who discussed the important role of harmonizing policy and practice to scale implementation of water-smart rangeland restoration. He also reminded session participants that rangelands are important sources of livelihood and that restoration activities must address sustainable use by humans, including support for the extension of resources and management programmes. In closing the session, Stephen Mureithi reiterated the multiple benefits of rangeland restoration including enhancing food and nutrition security, water security, resilience building against climate change, reversing land degradation, and halting biodiversity loss. He called on governments, agencies, and non-governmental organizations to co-work with communities to enable them to achieve restoration in landscape scales.

 

This session at the 2023 World Water Week marks a pivotal moment for rangelands, and came at the timing couldn’t have been better to complement some exciting news received the week prior. The Swedish Research Council for Sustainable Development, Formas, announced grant funding for the research project Scaling rangeland restoration in drylands through synergies in the biodiversity – water- climate nexus (Restore4More) led by SLU in partnership with CIFOR-ICRAF, the University of Nairobi, Makerere University, Stockholm University, Linköping University, IGAD-ICPALD, SIWI, and Vi Agroforestry. The long-term goal of Restore4More is to generate knowledge on the biodiversity-water-climate nexus that can contribute to large-scale, long-lasting, and effective rangeland restoration in the drylands of East Africa for increased climate change adaptation and mitigation, enhanced biodiversity, and water and food security.

SASUF (South Africa University Forum) is a transformative project uniting 40 universities from Sweden and South Africa. The goal is to bring researchers, teachers, students, university leaders and stakeholders together to develop joint solutions to meet the challenges posed by the UN Sustainable Development Goals (SDGs) and Agenda 2030.

Within the SASUF network, there is the SASUF Student Network, a group of student representatives from each partner university. The student network is an innovative, international and multidisciplinary group formed by students from both undergraduate and postgraduate level. The goal of this project is to strengthen the academic relationship between both countries and work towards the SASUF goals of the SDGs and Agenda 2030.

In my role as a student representative from SLU, I travelled to Cape Town in late March to meet my colleagues for the SASUF Research and Innovation Week 2023 as well as the Student Network Summit 2023. During an entire week, researchers and students from across the world linked to Swedish and South African universities assisted in hybrid and in-person side events at the University of Western Cape, the venue for the meeting.

The Student Network hosted two Satellite Events in ‘Decolonising Education – Africanisation of Higher Education Institutions’ and ‘Student Participation in Internationalisation – How Can We Empower Students?’ and a full 3-day Student Summit. During the Student Summit, the representative students hosted their own sessions about Gender Equality, Food Security, Student Empowerment, Decolonisation of Education and Mental Health, attended workshops, held a session for the Vice Chancellors on the topic of Science Diplomacy and Sustainable Student Networks, participated in a discussion hosted by the Swedish Embassy and presented in the closing ceremony.

The Research and Innovation Week 2023 worked as the perfect occasion for the South African and Swedish representatives to meet and strengthen the ties already created during months and years of meetings. The student network was created in 2019, and due to the pandemic, many of them had never had the opportunity to meet in person. The engagement from the students at the conference was proof that they are willing to take the baton from previous generations of researchers and learn and work with them, in an environment where each person’s opinion is respected.

In addition to attending the conference and getting to know the world of academia, the students valued the opportunity to get to know the life in the city and the context beyond the walls of the university. Knowing the reality of the local population is a key aspect to create projects adapted to the future needs of people in South Africa and Sweden.

The Student Network will continue working towards its goals of increasing and enable student influence in SASUF and research, facilitate students’ empowerment and inspiration and adding social value to the communities by working with cultural sensitivity and international collaborations.

As written in our document ‘Action Points and Highlights – SASUF Student Summit 2023’, on behalf of all the students, we want to extend our gratitude for a great week. But – let us not stop here. Let us continue to jointly create sustainable, prosperous, and equal societies now, as well as in the future. Student influence is vital for a fair and just higher education system, where students work with – and not against – the universities. We hope to continue making this a reality together with all of you.

See you in Sweden next year for the SASUF Research and Innovation Week 2024, co-hosted by SLU! SASUF will continue working every day for a sustainable future.

 

1. Act Local, Think Global; an exchange of ideas with JKUAT Nairobi

An ongoing, unique collaboration between Swedish University of Agricultural Sciences (SLU) Alnarp and Jomo Kenyatta University of Agriculture and Technology (JKUAT) Nairobi started out as an exploration of student’s innovative ideas related to spatial design/solutions addressing global challenges with local site specific actions.

A collaborative model between the departments of Landscape architecture in Alnarp and Nairobi was created with an aim to contribute to the Student competition set up in affiliation with the World Congress of International Federation of Landscape Architects (IFLA) to be held simultaneously in Stockholm and Nairobi in September 2023. The Swedish part of the course is now well on its way into the final stretch. In this Blog mini-series we want to share some of the insights and highlights of this unique collaboration, as faculty and students of SLU.

How do we understand the scales of “Global” and “Local”?

Our action within our local communities and context eventually impacts resilience at a global scale. For example, the resources we use, and our daily lifestyle ultimately have global consequences. These lifestyles are conditioned by, as well as impacted by landscape design and solutions, which in different ways can enable or constrain ways of living. At the same time, global and transnational political agendas such as Agenda 2030 or the UN Convention of Children’s Rights (CCR) affect the local practice of landscape planning and design. How we empower the young generation, will most likely effect their decisions in the future. The inter-dependencies between the local and global becomes tangible when we collaborate on a sites shrouded in similar challenges. To create a resilient and sustainable future for all life on earth, planning and design of landscapes requires to embed local site-specific knowledge within a larger understanding of their global effects.

How do we concretize this in a course?

To demonstrate this through the course we constructed a possibility for the students to work with and compare two sites, one in Kenya and one in Sweden. Both sites face challenges related to water management but in distinct social, political, and climatological contexts. How do we interact with local context, understand spatial processes and handle local politics? These are a few of the challenges that are addressed in this course preparing the students for working cross-equatorially in their future career.

The sites chosen are Nyhamnen in Malmö and Nairobi dam. Nyhamnen is a former harbour area claimed from the sea with vast areas of hardscape and quays. This has been a place of departure and arrival, still harbouring structures for connecting the land and the ocean. The city of Malmö is now planning to extend the city on to the site, embracing the diversity of Malmö and making space for social and biological processes that will colonize the area.  Nairobi dam, is an artificially constructed reservoir to capture water for the urban elite also offering this strata, recreational opportunities of sailing etc. A few decades later, the expansion of an urban marginalized settlement on one of its banks has transformed Kibera into the second largest slum in Africa. Devoid of water this space today is used for urban agriculture with peripheral areas collecting solid waste and sewage form the informal settlements as well as from other parts of the city conveyed by a network of three rivers.

How do we solve the logistics and cooperation in the courses?

Due to the different university terms, the JKUAT course started in January ending in April, where the students began with the Swedish site of Nyhamnen. The SLU course began in March and ends in June. During the courses, zoom lectures and reviews between the two universities has been held frequently. These digital meetings was complemented with IRL tutoring when two teachers from Sweden, Emily Wade and Nupur Prothi visited Kenya in March. They were able to meet the students at JKUAT and discuss their inspiring work on the Swedish site. This was also an opportunity to connect with JKUAT faculty and visit the site and meet Landscape Architects who were working within Kibera.

The Swedish part of the Master’s course started in the middle of March with a week’s visit from two Kenyan faculty members Caleb Toroitich and Caroline Ofafa, and two students Hilda Omuhindi and Victors Odiwa. In an extremely intense week we got to know the Kenyan site through lectures and movies from the site delivered by our Kenyan colleagues. We were able to take them to visit the Nyhamnen site in Malmö. Our Swedish students got to discuss and give feedback to the visiting Kenyan students on their proposals for Nyhamnen. Most importantly, the conversations and discussions strengthened mutual respect, laying the foundation for future collaborations.

What are the insights so far?

One of the important insights is that the education system in both countries have many similarities with a similar manner of teaching, design and practice of the landscape architecture profession. Early in our digital interactions, where we as SLU tutors reviewed the JKUAT students’ work in progress, we discovered that their analysis, sketches and proposals follow similar methodology and focus as our students. Our educational systems are also structured similarly at bachelor’s level even though the Kenyan education is younger than the Swedish program, which recently celebrated 50 years.

We do talk about the same global challenges, but site specific tangible problems are mostly very different. Multiplicity of cultures, dense urban populations, economic divides and a vibrant equatorial culture contrast somewhat with a Nordic population in a temperate and arctic landscape with low population pressure, abundance of open public space and ample natural resources.

What new perspectives on water access, use and design can be explored when collaborating with students from a country with vastly different challenges?

If there is an antithesis to a post-industrial harbour in a northern European, medium-sized town, it could, at first glance, be that of an overgrown dam in Nairobi, Kenya. It is in this economic, social, environmental, and not the least spatial contradiction that our team has approached the question of water access, use and design.

Nyhamnen is a constructed landfill, developed in order to expand in a growing, global industry. Nairobi dam of today reminds of a landfill, but is a consequence of political and economic circumstances with adverse environmental and social effects. Nyhamnen is an area that has been used to a limited extent by the city’s inhabitants, whilst Nairobi dam borders to, and is to a large extent integrated in, Kibera, the second largest informal settlement in Kenya. Although both sites face challenges of pollution, Nairobi dam is subject to an accumulation of urban runoff, inadequate sewage systems and the outcomes of poor sanitation facilities carried by rivers and tributaries with a final outlet in the dam. Nyhamnen is subject to a preceding industrial pollution, and in periods of extensive rainfall, to urban runoff.

Working together with students from Nairobi has – this far – had several effects on our design thinking. Seeing the possibilities of “our” site through the eyes of the Nairobi students – and specifically through their design analyses and concepts, has challenged us in our interpretation of the site. Mitigating rising sea levels by sculpting the land into dramatic hills and valleys, as suggested by one Kenyan student, inspired us to explore unconventional design solutions. It also emphasized the urgency of the global climatic conditions and how these require critical measures. We are not only theoretically aware of this. Being prompted by students with a first-hand experience of the consequences of climate change as well as of political and economic conditions in interplay with these, reinforces our incentive to practicing it.

Nairobi dam has been subject to a range of programs and measures taken to improve the conditions of the reservoir. The obstacles that have hindered a long term and extensive development of the past waterscape are described in literature on the development of the Nairobi dam, that we have taken part of. Despite the difference in severity and scale between Nyhamnen and Nairobi dam, there are lessons to be learnt in implementing improvement measures in the case of the urban transformation of Nyhamnen too. In terms of water access, use and design, one of the obstacles of the Nairobi dam experience has been that the extent of the defined extent of the project and the site has been too small-scale. Without engaging the local community, taking into consideration climate change, pollutants along the watercourse and economic circumstances affecting the use and misuse of the water, programs for treating the water risk being carried out in vain. The fluid character of water imposes on us a global perspective, in Nairobi dam as well as in Nyhamnen.

Act local, think global is as much the name of this class and a subtheme in the IFLA of 2023 as it is a method for learning from dramatically contrasting circumstances and applying them to our local conditions. An antithesis can also be a design tool that reveals a global parallel.

The repurposing of the former industrial harbour district Nyhamnen in Malmö will give space for and enable many purposes for the city. The coastal line and water will be accessible for the general public, enabling spaces for recreation and leisure. The amount of available space is also important regarding the demand on housing and Malmö City’s goal of densification. Access to the area and remnants of the harbour industry is also an important part of the city’s heritage and identity. There are also challenges with these possibilities. Envisioning how the new city district will function and be shaped by social life can be difficult. It therefore becomes necessary to think of how to activate a space rather than only imagining a static vision of what the new district should be. A big part of this challenge is to understand what qualities the space currently contains and designing with undiscovered potentials in mind.

Kibera public space project

The situations and projects of Kibera are vastly different from any situation in Nyhamnen, though the underlying ideas of community driven processes are inspiring for the urban development and activation of public spaces in Nyhamnen. It is not only the commonality that is relevant, but the differences in approaches which can be thought provoking in a necessary way. In KDI’s public space projects, multi functionality has been a big focus. Combined use of public space to work with sanitation, management of crime and availability of drinking water. Also engaging with social and economical challenges when working with climate related issues is helpful in creating solutions that are sustainable on more than one level. Even though much might be different from Nyhamnen, the question of multifunctionality in an increasingly dense environment is just as relevant in Malmö and many other cities.

Kibera is mentioned to have a strong social fabric and sense of community activism, giving community driven processes much potential. This strength in community and enabling of bottom up movements is something that sometimes is missing in large developments such as Nyhamnen. Bottom up movements aren’t unique to Kibera, but the demanding environment of Kibera also requires community structures and engagement. Highlighting the importance of the people being able to have their voices heard. This can also function as a reminder of core values that if not valued and protected could be overlooked in a seemingly well thought out and well functioning system.

Act local, Think global

The completely different preconditions of Nairobi and more specifically Kibera, demands a different approach to solving issues than what is praxis in Malmö. This highlights the value of acting local and thinking global, as different local contexts allow or even demand different approaches. As issues relate to human and ecological themes always are a common denominator for people and cities. The local perspective can help influence new ways of thinking, understanding complexities and to come up with new solutions.
