Goldschmidt Conference abstract # 31444

The global food system's reliance on a few species threatens food and nutritional security. Species diversification, including indigenous species, is a viable option to address this issue. Diversity enhances food systems' resilience against climatic and economic shocks. It offers resources for improved breeds and allows farmers to mitigate risks. H...

Geochemistry provides useful research tools related to fundamental processes in Earth, Environmental and Planetary Sciences. It has a distinct identity among the academic communities in these subjects, yet there is no specific data on workforce diversity among geochemists. We present the first demographic data of UK geochemists from a voluntary ano...

People's coexistence with nature is one of the most important global challenges today. Addressing this challenge requires a fundamental change in one's attitudes, behaviours and practices. Given the overlap between conservation goals, and religious teachings and practices that focus on environmental sustainability, a faith-based approach is conside...

Macadamia nuts constitute a vital component of both nutrition and livelihoods for smallholder producers in Malawi. We conducted a comprehensive mixed-methods study, combining qualitative and quantitative analyses, to explore varietal preferences and production challenges among these farmers. Leveraging cross-sectional data from 144 members of the H...

The complex relationship between mining and agriculture in Africa is deeply rooted in a complex network of spatial, political, and socioeconomic dynamics. In Ghana, for instance, the forest agroecological zone, responsible for 57 % of food crop production, coincides with 61 % of mineral-rich areas. This overlap leads to significant implications, su...

Declining soil fertility limits smallholder macadamia productivity in Malawi. To reverse this trend, it is essential to apply organic and inorganic fertilisers in an efficient and effective manner. Yet, fertilizer recommendations for smallholder macadamia (Macadamia integrifolia) production in Malawi are not site-specific. Nutrient imbalances can o...

Geochemistry is applied across earth, environmental and planetary sciences research and is essential to fundamental discoveries and many strategies to develop a sustainable future. For such a diverse subject, an equally diverse community should be expected and aspired to, to fully benefit from all available talent and perspectives. In a first natio...

Geochemistry provides tools to address research topics across Earth, environmental and planetary sciences. Affiliated to these disciplinary departments/schools geochemists are working across the UK higher education institutions (HEIs). ‘Evaluating Diversity and Inclusion within the (geochemistry) Academic Ladder (E-DIAL)’, project funded by the UK’...

The development of societies, including spiritual development, is closely connected to forests. The larger interrelations among changing societies, transforming forest landscapes, and evolving spiritual values related to forests have yet to be extensively considered. Addressing this research gap is important to avoid the neglect of spiritual values...

This perspective article highlights the need for transformation in food and farming at three scales to promote a food system that meets UN Sustainable Development Goals. Food insecurity is still a persistent problem globally because of how food and farming sector is currently organized vs. how it should be organized if cultural traditions, environm...

The discussion of food availability has expanded beyond staple foods to foods required for healthy diets. These include fruits, tree nuts, pulses, and some vegetables. Traditional metrics such as production, supply, and trade are being contextualized by an understanding of the link to land use, specifically as it relates to biodiversity, climate ch...

There is a growing recognition of the importance of conservation beyond protected areas, in spaces of human-wildlife coexistence. Negative human-wildlife interactions are a key challenge, but a better understanding of the forms of tolerance and mutual accommodation would be useful for coadaptation toward coexistence. To date, however, studies of hu...

Climate change is altering suitable areas of crop species worldwide, with cascading effects on people reliant upon those crop species as food sources and for income generation. Macadamia is one of Malawi’s most important and profitable crop species; however, climate change threatens its production. Thus, this study’s objective is to quantitatively...

Climate change is altering suitable areas of crop species worldwide, with cascading effects on people and animals reliant upon those crop species as food sources. Macadamia is one of Malawi's most important and profitable crop species. Here, we used an ensemble model approach to determine the current distribution of macadamia producing areas across...

Identifying the impacts of anthropogenic fires on biodiversity is imperative for human-influenced tropical rainforests because: i) these ecosystems have been transformed by human-induced fires for millennia; and ii) their effective management is essential for protecting the world's terrestrial biodiversity in the face of global environmental change...

The effective conservation and sustainable management of tropical peatlands in Southeast Asia is a major challenge. Pervasive deforestation, drainage and conversion to agricultural land, is disrupting the ecosystems’ ability to sequester atmospheric carbon. Conserving peatlands in an intact state has been described as a “low hanging fruit in tackli...

Macadamia is an essential commodity crop in Malawi. The nuts are a lucrative commodity and are used for household consumption, income generation among farming families and as a foreign exchange earning crop at country-level. Macadamia production in Malawi has increased significantly in recent years. Malawi is the seventh top producer of macadamia n...

Successful attainment of SDG17 is essential for implementing the other 16 SDGs, all of which depend upon secure means of implementation and durable partnerships. Funding for forests from ODA and other sources has trended upwards since 2000, providing reason for cautious optimism. However, REDD+ finance is declining. Private sector investment remain...

Despite considerable achievements in the field of conservation, biodiversity continues to decline and conservation initiatives face numerous barriers. Although many of these barriers are well known, for example insufficient funding and capacity, there has been no systematic attempt to catalogue and categorize them into a typology. Because risks com...

This is part of my PhD research work on macadamia production in Malawi.

Adaptation to environmental change, including biodiversity change, is both a new imperative in the face of global climate change and the oldest problem in human history. Humans have evolved a wide range of adaptation strategies in response to localised environmental changes, which have contributed strongly to both biological and cultural diversity....

A key obstacle to conservation success is the tendency of conservation professionals to tackle each challenge individually rather than collectively and in context. We sought to prioritize barriers to conservation previously described in the conservation literature. We undertook an online survey of 154 practitioners from over 70 countries to ascerta...

Tropical peat swamp forests are invaluable for their role in storing atmospheric carbon, notably in their unique below-ground reservoirs. Differing from terra firme forests, the peat-forming function of tropical swamps relies on the integrity of discrete hydrological units, in turn intricately linked to the above-ground woody, and herbaceous vegeta...

International food security and nutrition studies focus mainly on hunger rather than dietary diversity and the nutritional requirements essential for a productive life. The authors present a method that processes Food and Agriculture Organization food supply data into World Health Organization food groups to determine whether national food supply s...

African smallholder farmers produce food both for home consumption and commercial purposes, but these farmers are often net food buyers in local markets. To what extent do markets play a role in making food available and accessible throughout the year? This study assessed: (a) the extent of smallholder farmers' involvement in market trading network...

The exploitation of natural resources by people generally has detrimental effects on nature but in some cases anthropogenic activities can result in changes to the natural environment that produce new habitats and increase biodiversity. Understanding and supporting such cultural aspects of land use is an important part of effective conservation str...

The paper suggests a minimum set of abiotic and biotic threshold indicators and progress indicators for forest landscape restoration (FLR), then also briefly discusses progress indicators of pressures and project outputs. FLR aims to restore multiple functions of forests at a landscape scale. It is predicated on the hypothesis that restoration prod...

Contrary to expectations, some human-modified landscapes are considered to sustain both human activities and biodiversity over the long-term. Agroforestry systems are among these landscapes where crops are planted under native shade trees. In this context, ancient agroforestry systems can provide insight into how farmers managed the landscape over...

EXECUTIVE SUMMARY When dominant or mainstream perceptions and concepts have an undesired impact on nature and its contributions to people, promoting alternative perceptions and concepts may transform practices towards more desired impacts (established but incomplete). Individual perceptions of the surrounding world are organized into concepts that...

Reviewing the discussion on invasive species management in the literatures on nature conservation and environmental geography, this article puts forward an approach to invasive species management fit for the Anthropocene. It suggests that the biosecurity-driven rhetoric on invasive species needs to be discarded in favor of a more pragmatic approach...

Full text accessible at: http://dx.doi.org/10.1177/0379572117723135 Background: Sub-Saharan Africa is the only region in the world where hunger is prevalent in over one-third of the population, with smallholder farming households, producers of over 80% of Africa’s food, facing both calorie and micronutrient deficiencies. With agricultural systems...

This study explored the associations between dietary patterns and farm diversity as well as socioeconomic variables during two seasons in rural Western Kenya. As a mean of two surveys, the average dietary diversity scores (DDS) of households and women were low, implying low household economic access to food and low women's dietary quality. The Food...

The relationship between large herbivore numbers and landscape cover over time is poorly understood. There are two schools of thought: one views large herbivores as relatively passive elements upon the landscape and the other as ecosystem engineers driving vegetation succession. The latter relationship has been used as an argument to support reintr...

This paper presents a study of phytoliths (opal silica bodies from plants) from sediment sequences obtained from two tropical forest patches in the Western Ghats of India: a sacred grove (sequence covers last 550 cal BP) and a forest patch in a plantation (sequence covers last 7500 cal BP). The sites are located at mid-elevation (c. 650–1400 m abov...

A new global synthesis and biomization of long (> 40 kyr) pollen-data records is presented and used with simulations from the HadCM3 and FAMOUS climate models and the BIOME4 vegetation model to analyse the dynamics of the global terrestrial biosphere and carbon storage over the last glacial–interglacial cycle. Simulated biome distributions using BI...

Conservation and development share an intertwined history dating back to at least the 1700s. But what are the prospects for reconciling the two, and how far have we come with this project? This book explores these questions through a detailed consideration of the past, present and future of the relationship between conservation and development. Bri...

The idea of climate change has been enforced by its similarities with belief systems. It may come as a surprise to scientists, the media and climate activists participating in climate change discussions that they are unconsciously following models rooted in belief systems. These models include an emphasis on existential anxiety and the public expre...

Sacred natural sites (SNS) are instances of biocultural landscapes protected for spiritual motives. These sites frequently host important biological values in areas of Asia and Africa, where traditional resource management is still upheld by local communities. In contrast, the biodiversity value of SNS has hardly been quantitatively tested in Weste...

Background An extensive body of literature in the field of agro-ecology claims to show the positive effects that maintenance of ecosystem services can have on sustainably meeting future food demand, by making farms more productive and resilient, and contributing to better nutrition and livelihoods of farmers. In Africa alone, some research has esti...

Unsustainable hunting threatens both biodiversity and local livelihoods. Despite high levels of research effort focused on understanding the dynamics of bushmeat trade and consumption, current research is largely site specific. Without synthesis and quantitative analysis of available case studies, the national and regional characteristics of bushme...

Logging, deforestation and oil palm plantations have increased forest fragmentation in Borneo. Given the extent of forest loss and logging, evaluating the ability of remnant forests, especially fragments and riparian buffers, to provide aboveground biomass (AGB) storage and retain tree biodiversity is essential. This paper examines the variation in...

Healing Animals, Feeding Souls: Ethnobotanical Values at Sacred Sites in Central Italy. Ethnobotanical knowledge is a fundamental repository of the values and applications of different plants. This knowledge is often related to spiritual beliefs and religious sites, where plants have been nurtured and conserved for their use in rituals and traditio...

The time taken for forested tropical ecosystems to re-establish post-disturbance is of widespread interest. Yet to date there has been no comparative study across tropical biomes to determine rates of forest re-growth, and how they vary through space and time. Here we present results from a meta-analysis of palaeoecological records that use fossil...

Assessment of forest structure parameters via remote-sensing data offers the opportunity to examine stand parameters and to detect degradation and forest dynamics, such as above-ground biomass (AGB), at the landscape scale. While much attention has focused on spectrum-based and radar backscatter approaches for assessing forest biomass, texture-base...

The focus of this study is to assess the efficacy of using optical remote sensing (RS) in evaluating disparities in forest composition and aboveground biomass (AGB). The research was carried out in the East Sabah region, Malaysia, which constitutes a disturbance gradient ranging from pristine old growth forests to forests that have experienced vary...

* Priority question exercises are becoming an increasingly common tool to frame future agendas in conservation and ecological science. They are an effective way to identify research foci that advance the field and that also have high policy and conservation relevance. * To date, there has been no coherent synthesis of key questions and priority re...

This chapter draws on long-term ecological studies from across the globe to reconstruct the history of deforestation and forest fragmentation. It includes studies from a variety of forest biomes focusing on the last 11,500 years (the Holocene), paying particular attention to forest fragmentation as a result of expanding agricultural frontiers. Piec...

This book with 10 chapters (following an Introduction) covers the major questions of forest fragmentation as general questions affecting the world's forest biodiversity, ecosystem function and ecosystem services. These are not merely case studies from particular places in the world, confirming what we already know. Rather, these are carefully selec...

Faster-than-expected post-glacial migration rates of trees have puzzled ecologists for a long time. In Europe, post-glacial migration is assumed to have started from the three southern European peninsulas (southern refugia), where large areas remained free of permafrost and ice at the peak of the last glaciation. However, increasing palaeobotanical...

The first aim of the chapter on leadership and listening: inspiration for conservation mission and advocacy is to encourage conservation practitioners to take seriously their duty to engage sensitively with diverse faith communities (from local to global) and with their leaders (non-political as well as political), and to temper the sense of urgenc...

The importance of herbivory as a long-term driver of ecosystem change is a topic that has been hotly debated over the past few years. An understanding of the interaction between herbivores and ecosystems is particularly important for conservation policies aimed at re-wilding. Dung fungal spores have been highlighted as an important potential proxy...

Agricultural expansion remains one of the leading causes of deforestation, biodiversity losses and environmental degradation across the world, especially in the tropics (Angelsen et al., 1999 and Norris, 2008). From 1961 to 1993, the world population increased by 80% (Goklany, 1998). Due to the rapidly expanding human populations large increases in...

Patterns of endemism in the Neotropics have been explained by restriction of forest to ‘refugia’ in arid cold-stages of the Quaternary (Haffer J (1969) Speciation in Amazonian forest birds. Science 165: 131–137). The palaeoecological record, however, shows no such forest contraction. We review palaeoecological and phylogenetic data on the response...

There is growing recognition that the fate of the world’s terrestrial biodiversity depends on the management of human-dominated tropical forest landscapes. While global environmental change is transforming the ecology of tropical forests, a number of studies have also demonstrated that tropical forests are able to recover following disturbance. But...

Background/Question/Methods Large herbivores, whether domesticated or wild, are increasingly recognised as ecosystem engineers across most of the Earth’s biomes, both in cultural landscapes and wilderness areas. If present in sufficient density, the disturbance regime they generate on the long term is significant enough to deeply modify vegetatio...
