Dodder (Cuscuta spp.) comprises of parasitic annual plants belonging to the Family Custaceae. The species are sometimes included in the family Convolvulaceae (Morning Glories). Dodder infests many crops, ornamental plants, native plants, and weeds worldwide. Dodder has slender, twining or thread-like bright stems that vary from pale green to yellow or bright orange which are readily seen against the foliage of the host plants. The genus, Cuscuta which has more than 150 species, is found throughout the temperate and tropical regions of the world, with the greatest species diversity in sub-tropical and tropical regions. Cuscuta campestris (Field Dodder) is the most widely distributed, attacking a wide range of hosts leading to large economic loss on many flowering plants (Parker and Riches, 1993).
A KEFRI PublicationAbstract:
Forests and trees provide important ecosystem services that include; habitat to many organisms, conservation of water catchment areas, soil protection and carbon sequestration. In Kenya, it is estimated that 90% of the rural and peri-urban use fuelwood energy, and the formal forest sector employs about 50,000 people directly and about 600,000 indirectly - contributing about 3% of the GDP and 10% of the non-monetary economy.

The difficult choice - to conserve the living filters or utilizing the full
potential of wetlands: Insights from the Yala swamp, Kenya
:James Odhiambo Maua, Musingo Tito E. Mbuvi, Paul Matiku, Serah Munguti, Emily Mateche, Moses Owili
Wetlands are very productive ecosystems and provide a lot of goods and services to wetland-dependant communities worldwide. Despite their importance in terms of ecological, biological and socio-economic roles, they remain constantly under threat and many continue to be degraded and sometimes even lost at an alarming rate due to anthropogenic reasons.
Globally, wetlands are estimated to occupy approximately 6 −10% of the earth’s surface (Maltby, 1986; Schuyt and Brander, 2004) whereas in Africa; wetlands cover about 4.7% which is approximately 1.15 million km2 of Africa’s continental area.....
Charcoal value chains in Africa and their role for sustainable development, Published 2021.
:Anders Roos, Chemuku Wekesa, Doris Mutta, Mahamane Larwanou & Godwin Kowero.
Can the Forest Pledge support a sustainable charcoal sector in Africa? It is about understanding the big picture – and the details, write researchers from Sweden, Kenya and Niger.
The Forest Pledge of November 2 , signed by over 100 governments at COP26, aims at halting global deforestation before 2030. Similar initiatives to save the forests have been launched before, and we can this time learn from past mistakes. For Africa, the charcoal sector will have a key role to play in the outcome of the Forest Pledge due to its size and role for livelihoods. To succeed this time, the campaign must seriously involve key stakeholders, apply sound management principles and study the linkages between the state of the forests and associated value chains.....
Total Carbon Stock and Potential Carbon Sequestration Economic Value of Mukogodo Forest-Landscape Ecosystem in Drylands of Northern Kenya, Published 2021.
:Leley N., Langat D., Kisiwa A., Maina G. & Muga M.
Carbon sequestration is one of the important ecosystem services provided by forested landscapes. Dry forests have high potential for carbon storage. However, their potential to store and sequester carbon is poorly understood in Kenya. Moreover, past attempts to estimate carbon stock have ignored drylands ecosystem heterogeneity. This study assessed the potential of Mukogodo dryland forest-landscape in offsetting carbon dioxide through carbon sequestration and storage. Four carbon pools (above and below ground biomass, soil, dead wood and litter) were analyzed...
The main carbon pools on earth systems are atmosphere, terrestrial biosphere, ocean and Earth’s crust (Hoover & Riddle, 2020). Terrestrial ecosystems (mainly forest, soil and wetland), are the major carbon pool components on earth’s system (Beedlow et al., 2004; Lal et al., 2012; Xu et al., 2018) and largely contributes to the global carbon balance (IPCC, 2007; Hoover & Riddle, 2020). However, anthropogenic activities such as land-use change and combustion of biomass and fossil fuel are largely contributing to de-carbonization and accumulation of bio-spheric greenhouse gases (GHGs)—(Lal et al., 2012; Ciais et al., 2014; Friedlingstein et al., 2019)....
Guidelines for Establishment of Partnerships, Forest Resources and Resource User’s Boundaries in Kenya, Published 2021.
:Mogambi F., Mbuvi M.T.E. & Nahama E.
Participatory forest management has been globally studied and it has been argued that clearly defined boundaries for access of the community forest resources will lead to sustainable use of resources and enhanced sustainable livelihoods to the communities dependent on the forests for their survival. In contrast, however current studies indicate that while there are efforts to define spatial boundaries of resource use and the resource users within the community based forest management approaches, the definition of boundaries of resource use and resources users has proved more difficult, for instance when gathering relevant information and tools that can promote forest resource users partnerships, engaging of different stakeholders, assisting local communities to organize, preparing for negotiations meetings, procedures, rules, logistics and equity considerations, negotiating for the establishment of agreements and empowering of the local communities...
The dominant forest management approach today is premised on co-management, or collaborative management of natural resources between local communities that often rely on those resources, and the government. This model pre-assumes that co-management with local communities can lead to more sustainable and equitable resource use...
Community Use and Product Valuation of Forest Resources in Maasai Mau, Kenya, Published 2021
: Koech, C. K., Njuguna, J. W., Kiama, S. M., Maua, J. O., Kaigongi, M. M., Muganda, M. M., Nadir, S., & Kigomo, J. N.
Many people of a great variety of cultures and land-use practices live in or around tropical forests. Although these people are all in some way dependent on forests, they have little else in common. In recent years, however, it has become much harder for forest-dependent people to use local forests and their products, owing to deforestation, logging, population pressure or legal initiatives such as the declaration of state forests, national parks or wildlife reserves. In many countries, plans to protect forest ecosystems have failed to address the needs and knowledge of local forest-dependent communities (Kumar, Singh & Kerr, 2015). According to Isager, Theilade & Thomsen (2001) participation by local people is essential to any conservation effort. In forest conservation, participation is often associated with community forestry, which refers to forest management or management by people living close to the forest. Legal, political and cultural settings for community forestry vary widely, and the term covers a wide range of experiences and practices. Community forestry is often associated with South and Southeast Asia, but it is also common in other regions.
Forests play an important role in the livelihoods of local people in most developing countries. Local communities depend on forest resources for various products such as fuel wood, construction materials, medicine, and food. An estimated 1.6billion people depend to varying degrees on forests for their livelihoods and about 60million forest dwellers are almost fully dependent on forests. Furthermore, 350million people who live adjacent to dense forests depend on them for subsistence and income (World, 2004). It is estimated that 20-25% of rural peoples’ income is obtained from environmental resources in developing countries (Vedeld et al., 2007) and provide food reserve for use in periods of crisis or during seasonal food shortages (Langat, Maranga, Cheboiwo & Aboud, 2015). The ecological and economic significance of forest ecosystems in Kenya is widely acknowledged.
Indigenous knowledge and values:
key for nature conservation , Published 2021
: Krystyna Swiderska, Alejandro Argumedo, Yiching Song, Ajay Rastogi, Nawraj Gurung, Chemuku Wekesa and Guanqi Li
Most of the Earth’s biodiversity is located in the territories of Indigenous Peoples — around half a billion people who collectively manage about a quarter of the world’s land. Policymakers can no longer ignore the vast body of evidence showing that the traditional knowledge and rights of Indigenous Peoples and local communities are critical for addressing the crisis of biodiversity loss. Recent research with Indigenous Peoples in Peru, Kenya, India and China shows that Indigenous values and worldviews promote balance with nature and social equity. Strengthening Indigenous knowledge and values can lead to effective, locally owned, equitable and cost-effective conservation outcomes and contribute to global development goals. However, Indigenous knowledge and values face multiple threats. In advance of the Convention on Biodiversity (CBD) COP15 in China, policymakers must fully integrate Indigenous knowledge and values across the new Global Biodiversity Framework (GBF).
The traditional knowledge (TK) and ways of life of Indigenous Peoples and local communities (IPLCs) are critical in sustaining biological and cultural diversity. A 2019 global assessment found that biodiversity is generally declining least rapidly on Indigenous lands.1 New research shows that many lands characterised as ‘natural’, ‘intact’ or ‘wild’ have long histories of human use, and that recognising traditional societies’ deep cultural connection with biodiversity is essential in resolving the crisis of biodiversity loss.2
Genetic diversity and population structure of three
commercial indigenous Aloe species in selected ASALs
of Kenya, Published 2019
: Asenath Adienge, Gabriel Muturi, Stanley Nadir, John Gicheru, Johnson Kinyua and Jane Ngaira
Kenya is known for its rich diversity of native Aloe species with 59 species being reported by . The government of Kenya through the vision 2030 blue print, projects to curb food insecurity through sustainable management of dry lands and its genetic resources  which includes the Aloe species. The indigenous Aloe species are important non-wood plants with many economic and socio-cultural uses found in ASALs of Kenya which is home to more than 30% human population [3,4]. Due to their abundant socio-economic potential, the indigenous Aloe species in Kenya have been harvested by the local communities in the ASALs from their natural populations for many years for traditional medicinal use, cultural and aesthetic purposes . The commercial exploitation of Aloe species in Kenya was first reported in the 1960s with only five species being exploited for bitter gum production i.e. A. secundiflora, A. turkanesis, A. rivae, A. calidophila and A. scabrifolia [6,7]. Climate change, unsustainable harvesting of plants and their products, introduction of exotic species and pollution has been the key to unprecedented change in biodiversity worldwide . This unsustainable extraction from the wild causes threat to ecological balance and finally, may lead to complete loss of the species. This has raised concern locally and internationally on the level and impact of exploitation of wild populations and prompted a Presidential decree in 1986, banning commercial harvesting of Aloe species from their natural populations .
Genetic diversity is a key component to biodiversity analysis and therefore it’s important to have knowledge of the distribution, genetic diversity, environment and relations among plant varieties to recognize gene pools, identify gaps in germplasm collections and develop effective conservation and management strategies . There are morphological variations in some economically important Aloe species . The DNA based molecular markers are free from any environmental modulations unlike the morphological markers  and hence provide an important tool to determine the genetic diversity of Aloe species. The RAPD (Randomly Amplified Polymorphic DNA) and ISSR (Inter-Simple Sequence Repeat) marker systems have been widely used in genetic diversity studies of different plant species and offer alternative for studying genetic variation in Aloe species.
To address these challenges facing Aloe utilization in Kenya, this study therefore, determined the geographical distribution of the three commercial indigenous Aloe species (A. secundiflora, A. turkanensis, and A. scabrifolia) from selected areas in ASALs of Kenya to establish their distinct populations. In addition, the study evaluated the molecular characterization of the three Aloe species, using RAPDs and ISSR markers and mapped their genetic pools and structures. The output of this study was to provide important information in identifying gene pools, gaps in germplasm collections and development of effective conservation and management strategies for Aloe plants.
Operations and improvement needs in the informal charcoal sector: a participatory value stream analysis, Published 2021
: A. ROOS, D. MUTTA, M. LARWANOU, C. WEKESA and G. KOWERO.
More than two-thirds of households in Africa rely on wood energy for heating and cooking (IEA 2019). Charcoal is an affordable energy source for many low-income urban households and creates jobs and income along the supply chain (Khundi et al. 2011, Openshaw 2010, Schure et al. 2014, Sedano et al. 2016, Vollmer et al. 2017). However, charcoal production and use are largely based on unsustainable sourcing of wood, which in most cases lead to forest degradation (Bailis et al. 2015, Chidumayo and Gumbo 2013, Kiruki et al. 2017, Naughton-Treves et al. 2007, Ndegwa et al. 2016), and in other places to deforestation. Hence, the sector influences different Sustainable Development Goals in both positive and negative ways (UN General Assembly, 2015). Good knowledge of any supply chains’ processes and outcomes improves the understanding of its impacts on different sustainability indicators (Carter and Rogers 2008, Krajewski et al. 2019, Seuring and Müller 2008). This connection is also likely to apply to charcoal supply chains (Cerutti et al. 2015, FAO 2017: 118, Sola et al. 2017).
The charcoal sector in Africa has been characterised as informal and unsustainable, but it is of great economic importance to low-income households (Baumert et al. 2016, Jagger and Shively 2015, Schure et al. 2014, Shackleton et al. 2011, Shively et al. 2010). However, few studies have investigated the operations, lead times resources, and outcomes along the charcoal supply chain to identify opportunities for improving the sector (Doggart and Meshack 2017, FAO 2017: 118, Smith et al. 2017). Participatory approaches for analysing the charcoal supply chain are also rare, however, Zorrilla-Miras et al. (2018) applied this approach in a study on charcoal and land use in Mozambique.
Laboratory and Greenhouse Evaluation of Melia volkensii
Extracts for Potency against African Sweet Potato Weevil, Cylas puncticollis, and Fall Armyworm, Spodoptera frugiperda, Published 2021

Insect control products of plant origin could offer more sustainable alternatives to synthetic insecticides because they have low mammalian toxicity and low persistence in the environment . The focus of our study was on Melia volkensii, a drought-tolerant, fast-growing tropical tree species that grows in semi-arid areas of East Africa that is widely used in folk medicine for the treatment of various illnesses, such as diarrhea, pain and skin rashes [2–4]. Aqueous leaf extracts of the tree are also traditionally used to control ticks and fleas . M. volkensii is a suitable dryland agroforestry tree and is a source of highly praised mahogany timber and termite-resistant poles . M. volkensii seed kernel extracts have shown antifeedant and growth inhibition activity against several insect pests [7–10]. Insect antifeedant compounds such as salannin, volkensin, 1-tigloyl-trichilinin, 1-cinnamoyltrichilinin and 1-acetyltrichilinin have also been isolated from M. volkensii fruits [7,11]. Findings of previous studies and indigenous knowledge on M. volkensii makes this tree an interesting candidate for exploitation as a potential source of insect control products against insect pests of economic importance in Africa. The African sweet potato weevil (SPW), Cylas puncticollis (Boheman), and fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), are major insect pests of economic importance for sweet potato and maize farming in Africa, respectively. Significant sweet potato damage and economic losses are caused by C. puncticollis which oviposit in the vines and tubers . These weevils cause up to 100% yield loss [12–14], and the damage from weevils continues to increase during storage . Their larvae feed and tunnel in the tubers, causing reductions in marketable yield and quality . The tunneling produces terpenes which cause bad odors and bitter taste, rendering the sweet potato unpalatable and unmarketable . The terpenes can affect mammalian liver and lungs . The insect also infests the leaves and flower seeds . Infestation occurs during the dry season when high temperatures crack the soil surface, thereby exposing the tubers. Infestation can also occur through planting vines . Application of parathion and chlorpyrifos insecticides have been used in overcoming weevil infestation on sweet potato, however pesticide residues have been reported . Biopesticides such as azadirachtin and spinosad have been evaluated for their efficacy against the sweet potato weevils in the laboratory, but no studies have been reported on field trials .
Towards a Biocultural Heritage Territory in Rabai Cultural Landscape: Exploring Mijikenda Cultural Values and Practices for Sustainable Development - Case Study for the Project ‘Indigenous Biocultural Heritage for Sustainable Development’, Published 2021
: Chemuku Wekesa, Leila Ndalilo & Krystyna Swiderska
Biocultural Heritage Territories (BCHTs) are mosaics of land uses, deeply linked to Indigenous knowledge systems embedded in cultural traditions. The Potato Park in Cusco, Peru is perhaps the best-known example of a BCHT, where Indigenous knowledge and practices effectively combine food production with sustainable development, biodiversity conservation and ecosystem protection.
This study was conducted as part of the ‘Indigenous Biocultural Heritage for Sustainable Development’ project (2018-2021), funded by the Sustainable Development Programme of the British Academy. The project explored how Indigenous Peoples’ worldviews, wellbeing concepts, cultural values and customary laws promote or hinder biodiversity conservation and sustainable development. Conducted with the Rabai sub-tribe of the Mijikenda Indigenous people in Kilifi County, coastal Kenya, this case study was coordinated by the Kenya Forestry Research Institute (KEFRI), working closely with the Rabai community. It examined the interconnections between culture and biodiversity, and how biocultural heritage contributes to Sustainable Development Goal 2 ‘End Hunger’. It also sought to contribute to the establishment of a collectively-governed BCHT in Rabai, and used the Potato Park’s decolonising action research approach where research is co-designed and facilitated by Indigenous community researchers.
Energy in Woody Biomass: And the Industries that are Using it, Published 2020
: Nellie Oduor, Emily Kitheka & Churchill Ogutu
In Kenya, biomass energy resources are derived from forests - closed forests, community woodlands, farmlands and plantations as well as agricultural and industrial residues. This accounts for about 68 per cent of all energy consumed and for 90 per cent of rural household energy needs. The main sources of biomass for cooking and heating energy are charcoal, fuelwood and agricultural waste. Various industries use biomass energy in their processing; these include tea and edible oil processors. A study in 2013 that analysed the demand and supply of wood products in Kenya indicated that firewood and charcoal supply stood at 13,654,022m3 and 7,358,717m3 while demand stood at 18,702,748m3 and 16,325,810m3 respectively. Currently, there is unmet demand for biofuels with a 60% demandsupply gap. Forecasts for a 20-year period indicate a 20% increase in supply and 21.6% increase in demand by the year 2032 which signifies a gradually increasing deficit. However, most of the wood fuel is obtained from unsustainable sources and produced and utilized in inefficient technologies/devices. This exerts pressure on natural forests. The current moratorium by the Government of Kenya (February 2018 to date), banning logging on public and community forests has further widened the biomass fuel demand gap leading to escalating prices of charcoal.
