Demand for food and energy is constantly increasing in line with the global population and there are widespread concerns about environmental conservation. This chapter provides an overview of the identified potential to restore and utilize degraded land through an integrated biofuel- and food-production system that can also conserve the environment. Our findings highlight that the biofuel species Nyamplung (Calophyllum inophyllum L.) and Kemiri sunan [Reutealis trisperma (Blanco) Airy Shaw] in Indonesia are suitable to grow with local food crops on degraded land. Such integrated systems on degraded land are economically and socially favorable for local farmers. Producing biofuel and food on degraded land can also avoid compromising agricultural land use and production, while minimizing the harmful environmental consequences. However, for long-term sustainability of the system, and due to biodiversity and environmental concerns, there is a need to implement a mixed landscape approach using a “segregation” and “aggregation” land-management strategy, supported by competent government policies and local communities with sufficient social capital.

Protected Areas and Food Security: Unravelling the Issues
Recent research has highlighted the contributions of forests and tree-based systems to both dietary diversity and nutrition as well as agricultural production in the form of tree-based ecosystem services. Wild foods provide a significant nutritional contribution to the diets of rural dwellers, the majority of whom would be classified as some of the world’s poorest. In addition, it is now known that agricultural systems in the proximity of natural forest formations can exhibit greater productivity in terms of both yield and resilience to environmental shocks, as well as higher nutritional values. Yet, despite the important human-forest interactions and relative degrees of forest dependency, access to much of the global forest estate is increasingly regulated under the guise of biodiversity conservation. How this restricted access plays out when the ‘right to food’ is a deeply enshrined human right has been deeply contested. This chapter will outline the critical issues related to the right to food in the context of the growing call for the annexation of land for conservation.
The Baobab (Adansonia digitata L.) in Southern Kenya–A Study on Status, Distribution, Use and Importance in Taita–Taveta County
Baobab (Adansonia digitata L.) is a multipurpose, drought resistant, wild fruit tree, endemic to arid and semi-arid lands of Sub-Saharan Africa. Baobab populations have been showing a lack of regeneration, and therefore causes concern for the species survival. This study investigated the state, distribution and use of baobabs in an under-researched population in Kenya, to identify the potential for further use and development of baobab resources. A baobab population was chosen in Taita–Taveta County, covering a sample area of 2015 km2. A systematic stratified transect survey was done to map baobab distribution using 49 transects (0.5 × 3 km each). The diameter at breast height and other indicators were measured on all baobabs in the transects to assess population status and health. A household survey (n = 46) and focus group discussions (n = 12) were done following the transect survey to gain an idea on the uses and distribution of baobab. In total, 432 baobab trees were measured and recorded in the research area of 2015 km2. The baobabs grew in two clusters (i.e., areas with a baobab density of ≥0.08 baobabs/ha). Both clusters showed rejuvenating populations. The main factors identified by the respondents, positively and negatively influencing baobab distribution were environmental factors, wildlife, human impact and commercial value. The study area shows a great potential for baobab to become an important part of the diet, due to its current use as an emergency food during food scarce times, and the relatively healthy and stable rejuvenating populations.
Manila declaration on forest and landscape restoration: Making it happen
Globally, Forest and Landscape Restoration (FLR) is gaining widespread recognition from governments and policymakers for its potential to restore key ecosystem services and to improve human wellbeing. We organized an international conference on FLR, titled-Forest and Landscape Restoration: Making it Happen, between 25-27 February 2019 in Manila, the Philippines with 139 participants from 22 countries. The Forest and Landscape Restoration Standards (FLoRES) task force also met prior to the conference, which included a field visit to a pilot community-based forest reforestation site in Biliran Island, the Philippines. Based on the three-day conference, case study presentations, and FLoRES task force meeting, we prepared the Manila Declaration on Forest and Landscape Restoration to highlight the need to support quality of FLR efforts and outcomes in the tropics. Here we provide a synthesis of the main messages of the conference, with key outcomes including the Manila Declaration on Forest and Landscape Restoration, and ways forward to make quality FLR happen on the ground.
Farming systems and Conservation Agriculture: Technology, structures and agency in Malawi
Conservation Agriculture (CA) is advocated as an agricultural innovation that will improve smallholder famer resilience to future climate change. Under the conditions presented by the El Niño event of 2015/16, the implementation of CA was examined in southern Malawi at household, district and national institutional levels. Agricultural system constraints experienced by farming households are identified, and in response the technologies, structures and agency associated with CA are evaluated. The most significant constraints were linked to household health, with associated labour and monetary impacts, in addition to the availability of external inputs of fertiliser and improved seed varieties. Our findings show that such constraints are not adequately addressed through current agricultural system support structures, with the institutions surrounding CA (in both Government extension services and NGO agricultural projects) focusing attention predominantly at field level practice, rather than on broader system constraints such as education and health support systems. Limited capacity within local institutions undermines long term efforts to implement new technologies such as CA. It is vitally important that the flexibility of farmers to adapt new technologies in a locally-appropriate manner is not closed down through national and institutional aims to build consensus around narrow technical definitions of a climate-smart technology such as CA. To enable farmers to fully utilise CA programmes, interventions must take a more holistic, cross-sectoral approach, understanding and adapting to address locally experienced constraints. Building capacity within households to adopt new agricultural practices is critical, and integrating healthcare support into agricultural policy is a vital step towards increasing smallholder resilience to future climate change.

Ecological challenges for the buffer zone management of a West African National Park
In sub-Saharan Africa, the management of buffer zones around protected areas does not often take into serious account the needs of resource exploitation by the local populations or the conservation needs of these areas. We described the ecological characteristics and management issues affecting the buffer zone around the Fazao-Malfakassa National Park; a 192,000-ha protected area in central-western Togo of utmost conservation importance within the Dahomey Gap region. Within the buffer zone (10 km radius, 334,800 ha), we focussed on four high conservation value areas totalling 65,594 ha (20% of the total buffer zone area). Using 2015 sentinel-2 images we analyzed land cover patterns and described existing ecological zones. We complemented these with field surveys and interviews with 300 people living in 22 villages within the buffer zone to describe the conditions affecting the resident human population. Although over 60% of the total buffer zone area is degraded, we identified four areas of high conservation value (total area = 65,594 ha). Interviewees recognized that slash-and-burn was the most common form of land use, followed by agroforestry practices. Agriculture, charcoal, and firewood production were the main drivers affecting habitats, and land conflicts were recurrent due to the rise in human population. The decline in agriculture, reported by interviewees in some sectors, was attributable to ravages of crops by elephants. Three independent diversity indices showed that, in preserved zones, a greater diversity of animals (with similar utilization frequencies) were hunted than in degraded sites (where grasscutters were the dominant hunted species). There were also significant differences between degraded and preserved zones in terms of plants used for charcoal production and for non-timber forest products. We advocate the development of community-controlled hunting areas to enhance the conservation value of the four well-preserved zones. Instead, promoting sustainable agricultural production systems in the degraded areas can help to further stabilize the agricultural front and reduce land pressure on the park.
Taxonomic novelties and global biogeography of Montagnula (Ascomycota, Didymosphaeriaceae)
Whilst conducting surveys of lignicolous microfungi in Yunnan Province, we collected a large number of taxa that resemble Montagnula (Didymosphaeriaceae, Pleosporales). Our phylogenetic study on Montagnula involved analysing sequence data from ribosomal RNA genes (nc18S, nc28S, ITS) and protein-coding genes (rpb2, tef1-α). We present a biphasic approach (morphological and molecular phylogenetic evidence) that supports the recognition of four new species in Montagnula viz., M. lijiangensis, M. menglaensis, M. shangrilana and M. thevetiae. The global diversity of Montagnula is also inferred from metabarcoding data and published records based on field observations. Metabarcoding data from GlobalFungi and field observations provided insights into the global diversity and distribution patterns of Montagnula. Studies conducted in Asia, Australia, Europe, and North America revealed a concentration of Montagnula species, suggesting regional variations in ecological preferences and distribution. Montagnula species were found on various substrates, with sediments yielding a high number of sequences. Poaceae emerged as a significant contributor, indicating a potential association between Montagnula species and grasses. Culture-based investigations from previously published data revealed Montagnula species associations with 105 plant genera (in 45 plant families), across 55 countries, highlighting their wide ecological range and adaptability. This study enhances our understanding of the taxonomy, distribution, and ecological preferences of Montagnula species. It emphasizes their role in the decomposition of organic matter in grasslands and savannah systems and suggests further investigation into their functional roles in ecosystem processes. The global distribution patterns and ecological interactions of Montagnula species underscore the need for continued research and conservation efforts.
Targeting site conservation to increase the effectiveness of new global biodiversity targets
Global protected area extent has increased recently but often outside areas of biodiversity importance. Governments recently committed to conserving 30% of land and seas, especially “areas of particular importance for biodiversity.” Reviewing site-based conservation approaches, we propose harnessing key biodiversity area criteria to target such locations.
Monitoring Behaviour Change of Farmers to Support Ecologically Friendly Agricultural Management Program in Peatland Ecosystems
Conserving peatland areas requires the commitment and the capacities of all stakeholders, including farmers living within the areas. Two business models, agro-silvo-fishery and Trigona apiculture, have been established in a demonstration plot in the peatland ecosystem of Baru Village, Banyuasin, South Sumatra, as new options for farmers to improve livelihoods while also managing peatland sustainably. Trainings on sustainable production, post-harvest, and markets were provided to the rice-based farmers to help them manage new livelihood options. Monitoring the behavioural transformation of farmers engaged in the two business model pilots is a crucial aspect of the program. This is accomplished using the ADKAR approach, which posits that attaining long-term behavioural change involves progressing through stages of Awareness, Desire, Knowledge, Ability, and Reinforcement. A survey instrument was created to monitor farmers behaviour changes in (i) collective action, and (ii) managing agroecosystems sustainably, reflecting collaborative effort required to conserve peatland. Prior to the intervention program, a baseline survey (n=43) was conducted to record farmers’ current knowledge. The findings revealed that most farmers (60%) never joined a group but motivated to actively participate, whereas 25% of farmers had actively participated in groups and were eager to urge other farmers to join. Most farmers (52%) acknowledge the significance of safeguarding peatland areas but lack the knowledge to do so, whereas 25% have implemented ecologically friendly agricultural management in peatland areas. When the program began, none of the farmers were involved in agro-silvo-fishery or Trigona apiculture. According to a mid-program assessment aimed at recording the performance of the business models, 3 farmers have adopted apiculture with a total of 101 beehives. While none of the farmers adopt agro-silvo-fishery individually, 5 farmers produced organic fertilizer individually using the training program’s new competence. However, producing organic fertilizer as collective action was halted, suggesting farmers partiality to work individually rather than collectively. A final survey to assess behavioural changes is planned towards the end of the program next year. The ADKAR approach for monitoring farmers’ behavior change is useful for evaluating the performance of intervention programs and seek solutions to ensure it is aligned with the landscape level NRM goals.
