This book examines the challenges and impacts of poor diets and nutrition from current food systems and the potential contribution of biodiversity and ecosystem services in addressing these problems. It also presents a multi-country, cross-sectoral analysis of initiatives that have promoted local food biodiversity in four countries: Brazil, Kenya, Turkey and Sri Lanka.

This book critically assesses the role of agrobiodiversity in school gardens and its contribution to diversifying diets, promoting healthy eating habits and improving nutrition among schoolchildren as well as other benefits relating to climate change adaptation, ecoliteracy and greening school spaces. It features international case studies, spanning both developed and developing nations.

Growing evidence suggests that constraints to the availability and quality of tree seed can undermine the success of forest
and landscape restoration efforts and the delivery of associated benefits such as mitigating climate change and halting biodiversity loss.
Past experiences to promote tree seed supply have frequently shown limited outcomes over time, partly because of unexpected, deleterious

Rangelands can be described as land on which the vegetation
is predominantly grasses, grass-like plants, forbs or shrubs,
and often with trees that are grazed or have the potential to be
grazed by livestock and wildlife. They are diverse in their vegetation
driven by highly fluctuating rainfall, temperature and other climate
phenomena, and habitat for a wide range of wildlife, many species
of which are found nowhere else. Rangelands store vast amounts of
carbon and either originate or serve as freshwater catchment areas for

Sustainably managed non-native trees deliver economic and societal benefits with limited risk of spread to adjoining areas. However, some plantations have launched invasions that cause substantial damage to biodiversity and ecosystem services, while others pose substantial threats of causing such impacts. The challenge is to maximise the benefits of non-native trees, while minimising negative impacts and preserving future benefits and options.

Farming systems that support locally diverse agricultural production and high levels of biodiversity are in rapid decline, despite evidence of their benefits for climate, environmental health, and food security. Yet, agricultural policies, financial incentives, and market concentration increasingly constrain the viability of diversified farming systems.

Asia-Pacific Forest Genetic Resources Programme (APFORGEN) is a regional programme and network for the conservation of forest and tree genetic resources. Through its network of geneticists, forestry professionals and funding partners in 15 Asian countries, APFORGEN shares knowledge and good practices, implements multi-country research and development projects, operates a Regional Training Centre and serves as a one-stop-centre on forest and tree genetic resources information and initiatives in the Asia-Pacific.

Biodiversity flourishes in areas where natural processes, such as plant and animal reproduction and dispersion, take place without human interruption. At present, we estimate that such land where natural processes predominate (LNPP) covers 56% of terrestrial land. Here, the evolution of global biodiversity is modelled, as indicated by LNPP, for two scenarios for food and land-use systems change to 2050: a “Current Trends” pathway, based on current policies and historical trends, and a “Sustainable” pathway, depicting ambitious assumptions aimed at sustainable development.

In the face of global pressures of change and biodiversity loss, crop wild relatives (CWR) and wild-utilized species (WUS) urgently require conservation attention. To advance conservation, we assembled a national inventory of CWR and WUS in Canada. To assess current ex situ conservation of these plant species, we gathered a virtual metacollection of accession data from botanical gardens and national genebanks.

Current policy is driving renewed impetus to restore forests to return ecological function, protect species, sequester carbon and secure livelihoods. Here we assess the contribution of tree planting to ecosystem restoration in tropical and sub-tropical Asia; we synthesize evidence on mortality and growth of planted trees at 176 sites and assess structural and biodiversity recovery of co-located actively restored and naturally regenerating forest plots. Mean mortality of planted trees was 18% 1 year after planting, increasing to 44% after 5 years.

The challenges relating to biodiversity loss, food insecurity and climate change show the urgent need to make transition towards sustainable food systems in West Africa. To bring about such a transition worldwide, the United Nations’ Food Systems Summit was held in September 2021. One of the main outcomes of the Summit was the national pathways to sustainable food systems. This review analyses whether and how agro-biodiversity is addressed in the food system transformation pathways submitted by West African countries in the framework of the Summit.

Climate change and other anthropogenic threats are increasingly imperilling the diverse biomes of Central Africa, which are globally important for biodiversity, carbon storage and people's livelihoods. The objectives of this paper were to: (i) map the vulnerability of 100 socio-ecologically important priority tree species in Central Africa to climate change, fire, habitat conversion, overexploitation, overgrazing and (ii) propose a spatially explicit strategy to guide restoration and conservation actions.
