Hale, Stephen S. Current food system trajectories could push many of these mammals toward global extinction The analysis allowed for on-site evaluation of the presence of beneficial insects for agriculture, which was complemented by a survey of 20 producers. Many farmers are forced off their land as costs rise, even when they choose to continue growing traditional crops; the rush to cash in on lucrative new varieties drives up demand for farmland, making traditional farms unable to compete.

Biodiversity preservation in agriculture -

Having a greater diversity of genes, species and ecosystems makes production systems and livelihoods more resilient to shocks and stresses and often leads to more stable and efficient ecosystem service provision.

This is especially important to consider in the context of climate change. Biodiversity also contributes to food security and nutrition by providing nutritionally diverse foods. Wild species are also an important source of nutrition, rich in micronutrients, for many households around the world, yet many are under threat from overexploitation and habitat loss.

Food systems based on the sustainable use of biodiversity and traditional knowledge have the potential to provide food security and livelihoods in a sustainable manner, making them an important lever in attaining the SDGs.

The Sustainable Agriculture Transition presented in the 5th Global Biodiversity Outlook highlights how incorporating a greater diversity of crops and livestock, creating and maintaining well connected habitat for associated biodiversity, practicing sustainable soil management and reducing the use of synthetic inputs can increase biodiversity and ecosystem services without negatively affecting yields.

GBO-5 Agriculture Highlights The fifth edition of the Global Biodiversity Outlook GBO-5 provides a final assessment of progress towards the Aichi Biodiversity Targets. While nearly all of the Aichi Targets are relevant in some way to agricultural biodiversity, there are some specific elements of the Aichi Targets that are especially relevant to achieving healthy, productive and sustainable agricultural systems; these are Aichi Targets 3, 4, 7, 8, 13, 14 and For more information, see: GBO-5 Agriculture Highlights Biodiversity plays an important role in underpinning ecosystem functions and services that are essential for the productivity and sustainability of our food systems.

The shape and nature of such transformative change can already be identified through a series of transitions under way to a limited extent in key areas.

The key transitions to sustainable pathways related to agricultural biodiversity are: The Sustainable Agriculture Transition This transition recognizes the role of biodiversity, including pollinators, pest and disease control organisms, soil biodiversity and genetic diversity, as well as diversity in the landscape, for productive and resilient agriculture that makes efficient use of land, water and other resources.

The Sustainable Food Systems Transition This transition recognizes the potential nutritional benefits from diverse foods and food systems, and the need to reduce demand-driven pressures globally while ensuring food security in all its dimensions.

Upcoming: UN Food Systems Summit The Secretary-General of the United Nations has convened a Food Systems Summit to be held in The major causes of biodiversity declines and extinctions—habitat loss and fragmentation, and over-exploitation—are driven largely by demand for food.

Preventing such devastation will require major international investment aimed at increasing crop yields via sustainable intensification that would allow most countries to develop secure and sufficient food supplies on existing agricultural lands.

Failure to do so may render other conservation measures such as protected areas more difficult to implement and safeguard because countries and their citizens would have to clear land to meet their food needs. Crop genetic diversity is essential for discovering new traits that can control ever-evolving existing pathogens and thus maintain crop yields 12 ; for generating crop varieties to overcome new pathogens such as wheat stem rust 13 ; and for increasing yields and adapting crops to climate change 14 and Conserving global biodiversity will help protect the food supply that is essential for the long-term wellbeing of humanity.

The global food system threatens more species than any other area of human endeavour, through habitat destruction to create new farmland; overexploitation of marine and terrestrial species; and agricultural pollution of freshwater and marine ecosystems Figure 1A.

Of the ~25, species that the IUCN has identified as threatened with extinction, 13, are threatened by agricultural land clearing and degradation alone. In addition, some 3, species are affected by hunting and fishing, and 3, by pollution from the food system.

Threats from the food system are equally important across terrestrial, marine and freshwater systems Figure 1B , demonstrating its truly global impacts. Logging—listed as a threat for thousands of species—is often the initial step in land clearing that leads to new pastures and croplands. Figure 1A.

The number of species threatened with extinction that are affected by various human activities, based on IUCN data. Figure 1B. The proportions of threatened terrestrial, marine and freshwater species that are impacted by one or more of 10 major anthropogenic threatening factors, based on IUCN data.

For all three systems, global food systems are the greatest threatening factor. Figure 1C. For those threatened plant, animal and fungal species affected by the global food system, agricultural land clearing threatens 4-times the number of species threatened by any other factor.

However, agricultural pollution, and hunting and fishing still threaten about 3, species, each, globally. Agricultural land clearing has not stopped. Based on changes in the extent of agricultural land in each country, we estimate that from to , ~ million hectares of new croplands were created globally, and an additional ~ million hectares of natural ecosystems were converted into pastures The total land area of natural habitats thus cleared for agriculture during the past six decades is the size of the continental USA.

Harm is particularly severe for species with narrow ranges and specialized habitat requirements 23 , and for large-bodied species Current food system trajectories could push many of these mammals toward global extinction Similarly, large mammals of tropical South America could attain extinction risks in 50 years like those of present-day South and Southeast Asia The global agricultural land conversion that has occurred to date has fragmented natural habitats, separating remaining patches with farmland, fences, roads and other structures 29 and The resulting smaller, isolated populations are much more vulnerable to extinction 31, 32 and 33 ; many species still surviving in fragments may be on deterministic trajectories toward extinction 34 and However, a range of empirical studies, including a major synthesis 36 , have demonstrated that heavily fragmented landscapes and habitats lose large numbers of species over time, with smaller fragments and those separated by greater distances losing species more rapidly.

Preserving remaining large blocks of intact habitats is vital for biodiversity conservation. Agricultural land management is increasingly intensive, with nitrogen fertilizer and pesticide use now ~6 and 12 fold greater, respectively, than at the advent of the Green Revolution in 37 and This intensification has increased yields in many regions and so reduced demand for additional cropland and helped preserve some natural habitats 39, 40 and However, intensification can reduce habitat suitability for species that could otherwise survive in farmland 42 and has resulted in widespread declines in farmland biodiversity The resulting fertilizer and pesticide pollution threaten many marine and freshwater species with extinction 44 and Fishing and hunting can provide nutritionally important foods but overharvesting and the accidental harvesting of non-targeted species bycatch have caused extinctions and threaten many species see Figure 1 The global food system continues to expand in response to increasing food demand.

The global human population is projected to increase to about Ensuring that all people have access to a sufficient, nutritious and secure food supply is a moral obligation for the global community, but depending on how this is achieved, it might be achievable on existing croplands or could require ~ million hectares of additional cropland 55, 56 and The broad range of these future cropland-demand estimates reflects the range of possible future trajectories for food demand, dietary compositions, crop yields and food waste.

Land clearance will be highest in countries where large increases in food demand combine with low, and slowly increasing agricultural yields. Worryingly, these are the current trajectories in much of the most biodiverse regions on Earth: the tropics and subtropics Figure 2.

In contrast, the population of the rest of the world is forecast to increase by 0. Because people in high-income countries have diets that require ~8, kilocalories of crop production per day, compared to ~2, kilocalories in low-income countries, demand for crops may escalate greatly in Sub-Saharan Africa as their incomes rise 59 and In contrast to most high-income countries, where high or rapidly increasing agricultural yields on existing agricultural lands seem sufficient to meet demand increases, many regions in the tropics have low and slowly increasing yields Figure 3A Were current trajectories to continue, 13 Sub-Saharan countries would need at least 4-times their cropland by ~ million hectares of additional cropland in total Figure 2 62 , comprising all remaining land suitable for agriculture in some countries.

Similarly, some countries in Latin America and Southeast Asia would need to more than double their cropland area. Figure 2: Cropland demand in if national food demand and national yields follow past patterns and trajectories.

Note the projected preponderance of land clearing in the tropics. Based on analyses in Tilman et al. This possibility highlights the importance of food-system innovations.

We propose a three-part food system strategy for preserving global biodiversity: A Grow crops in more land-efficient and input-efficient ways B Plan land clearing to minimize habitat fragmentation; and C Decrease the growth in global crop demand via reduced waste and healthier diets. Rapidly increasing yields in low-yielding countries is essential for protecting biodiversity.

Unless yields rise as quickly as food demand, the food needs of billions of people must be met by land clearing. This will threaten remaining natural habitats and protected areas, and reduce the ethical and political feasibility of existing and new protected areas.

However, the protection of natural habitats does not need to, and should not, impose a cost on food security and sovereignty. These slow yield increases are not due to fundamentally lower potential yields.

The difference between the current low yields of some countries and the yields that could be attained is called the yield gap 63 and these remain large in many low-income countries.

There is therefore great potential for yield increases in many tropical countries. Rapidly closing yield gaps is of great importance for food security and preservation of biodiversity 64 and 65 , but, given the economic status of many of these countries, will require coordinated international investments.

Environmentally efficient and sustainable methods for increasing yields should be employed in each region and may require integrated farming methods on some soil types, and cultural and infrastructure changes Figure 3A.

In agriculture, biodiversity is also useful for humans: genetic diversity in crops and livestock helps guard our food supply against disease and other threats. Unfortunately, industrial agriculture prioritizes consistency and productivity over biodiversity, and relies on only a few varieties of plants and animals. Treating crops and livestock like parts on an assembly line rather than unique players in a dynamic system threatens both wild species and has serious implications for our own domesticated food supply.

This is an opportunity to showcase that we are shifting towards Biodiversity preservation in agriculture crop Ginseng for digestion on productive acres and moving away from maximizing production across all acres.

Doing so through the Conservation Exchange Pilot allows us to highlight how in field management of landscapes can contribute to positive biodiversity outcomes. The program will focus on southwest Manitoba and southeast Saskatchewan. The first step is to identify growers that want to voluntarily participate in converting marginal land within their fields from cultivated areas to forages.

Once the marginal areas are identified, a grower gets financial support in converting those marginal areas to forages. It's about taking those less productive areas out of production, saving the input costs and still making the acres productive for the grower.

For the Conservation Exchange Pilot, DUC will quantify the soil carbon, biodiversity, water quality and water quantity outcomes from that restored marginal areas land. The Government of Canada, and their provincial partners, will conduct quality assurance on the biodiversity outcomes of the MAP project.

This verification step is highly valued by the project partners. Marginal areas are seeded with commercially available grass and forage seed mixtures. They can increase habitat suitability for pollinators so growers can increase pollination rates. In taking marginal lands out of production, growers are saving on the input cost.

They are no longer putting in money every year and either losing money or not getting that return on investment back in those acres. It should be a financial benefit because that seeded forage can also be used, whether it's cut for hay or grazed.

It should have both a financial direct and indirect benefit to the growers. I have seen countless examples from the reclamation and water efficiencies and treatment at our NPK manufacturing, to our expert agronomic advice in the field. In addition, Nutrien is currently embarking on an enterprise-wide nature biodiversity and water assessment to look at our impacts, dependencies, risks, and opportunities related to biodiversity and water.

Why Biodiversity Matters

We sit at farm kitchen tables to support those who grow and raise our food. We sit at boardroom tables with the agricultural industry to help influence decision-making to include conservation. We partner with restaurants and agricultural supply companies to help them source sustainable ingredients and products while protecting and restoring nature.

And we work with governments at all levels by bringing our scientific expertise and conservation know-how to the policy table.

To find sustainable solutions in an increasingly complex world, we need pragmatic partnerships and conservation needs to have a seat at the table to ensure Canadian agriculture is recognized for more than just the food it produces. These inventories will improve on-farm decision making and create greater transparency for consumers who want reassurance that their food is derived from good land stewardship.

They will also help estimate the economic values of these ecological services provided by farmers and ranchers—ones that benefit all Canadians. Action: Optimize lands that are currently in production and provide incentives to re-naturalize land that is having a negative return on investment.

Action: Prioritize soil health. Establishing a National Strategy for Soil Health is the first, important step in this direction. As the world gathers in Montreal for COP15 , we encourage these leaders to consider our agricultural landscapes and how biodiverse these areas truly are.

Conservation at the table DUC sits at a variety of tables for discussions around food, farming and nature. Because people in high-income countries have diets that require ~8, kilocalories of crop production per day, compared to ~2, kilocalories in low-income countries, demand for crops may escalate greatly in Sub-Saharan Africa as their incomes rise 59 and In contrast to most high-income countries, where high or rapidly increasing agricultural yields on existing agricultural lands seem sufficient to meet demand increases, many regions in the tropics have low and slowly increasing yields Figure 3A Were current trajectories to continue, 13 Sub-Saharan countries would need at least 4-times their cropland by ~ million hectares of additional cropland in total Figure 2 62 , comprising all remaining land suitable for agriculture in some countries.

Similarly, some countries in Latin America and Southeast Asia would need to more than double their cropland area. Figure 2: Cropland demand in if national food demand and national yields follow past patterns and trajectories.

We propose a three-part food system strategy for preserving global biodiversity: A Grow crops in more land-efficient and input-efficient ways B Plan land clearing to minimize habitat fragmentation; and C Decrease the growth in global crop demand via reduced waste and healthier diets.

Rapidly increasing yields in low-yielding countries is essential for protecting biodiversity. Unless yields rise as quickly as food demand, the food needs of billions of people must be met by land clearing.

This will threaten remaining natural habitats and protected areas, and reduce the ethical and political feasibility of existing and new protected areas.

However, the protection of natural habitats does not need to, and should not, impose a cost on food security and sovereignty. These slow yield increases are not due to fundamentally lower potential yields. The difference between the current low yields of some countries and the yields that could be attained is called the yield gap 63 and these remain large in many low-income countries.

There is therefore great potential for yield increases in many tropical countries. Rapidly closing yield gaps is of great importance for food security and preservation of biodiversity 64 and 65 , but, given the economic status of many of these countries, will require coordinated international investments.

Environmentally efficient and sustainable methods for increasing yields should be employed in each region and may require integrated farming methods on some soil types, and cultural and infrastructure changes Figure 3A. Mean annual calorific yields for each of 3 UN economic groups and for 4 regions.

Total national harvest of kilocalories of food system crops was divided by hectares harvested each year. All countries in each economic group were then averaged to obtain the data shown. Note low average yields and yield growth in Latin American and African least developed countries.

Figure 3B. Relationship between agricultural intensification and average annual kilocalorie yields for 3 economic groups in 5 regions.

Each point is the mean across all countries in a group and region. Agricultural intensification involves numerous inputs, including various fertilizers, improved crop varieties, pesticides, labor, machinery, fuel and irrigation.

Here we use the rate of application of nitrogen fertiliser as a correlate of such actions, not as the underlying cause. Data from FAOSTAT. The Green Revolution demonstrated that higher yields require appropriate crop varieties, farmer knowledge, and the intensification of inputs or of other methods that increase soil fertility.

One indicator of intensification is the rate of nitrogen fertilization, since farmers who apply nitrogen at higher rates often also apply other inputs as needed. There is a clear relationship across economic groups between averaged national caloric yields of all crops combined and averaged national agricultural intensification as measured by nitrogen fertilizer application rates; Fig.

Yield stagnation Fig. Because of the data available, this analysis focuses on intensification via chemical fertilisers, but some elements or aspects of ecological, organic or regenerative agricultural methods may increase soil fertility and provide high yields with less or perhaps no chemical fertilization.

Agricultural intensification can cause water and air pollution and emit the potent greenhouse gas nitrous oxide, but these impacts are not inevitable and may even decrease per unit of output with higher yields Cover crops, including legumes, can also reduce nutrient loss and pollution: planted after harvest, they take up nutrients that could otherwise be lost from soil, and are then ploughed into the soil at the start of the next growing season, recycling nutrients and increasing soil fertility.

Biodiversity itself can also help with sustainable intensification. Similarly, planting a forage legume and maize in alternating rows in sub-Saharan Africa greatly increased maize yields via increase soil fertility and decreased pest abundances At larger scales, countries that grow a greater diversity of crops tend to have lower year-to-year fluctuations in their total national food harvest 80 , contributing to food security.

Mixtures of varieties of a single crop can increase yields by decreasing disease incidence 81 , or can eliminate the need for fungicides to control pathogens Finally, existing diversity within crop species can be used to identify and develop varieties that are better suited to specific environmental conditions—focusing such efforts on crops and varieties for tropical regions could bring enormous benefits.

Increased agricultural yields will be essential for reducing the pressure to convert natural habitats into croplands and pastures. However, international assistance to increase yields should be accompanied by land-use zoning and planning to minimize the fragmentation of remaining natural lands.

The formal establishment of protected areas and pro-active policies that link aid for yield increases to natural habitat preservation will also be necessary A failure to implement such policies could lead to unnecessary land clearing and fragmentation, and reduce the land-saving benefits of yield increases 84, 85, 86 and Such interventions can also direct agriculture towards designated areas that have both fertile soils and infrastructure that provides access to inputs and markets 88 , helping to both protect biodiversity and alleviate poverty.

Diets that can reduce the incidences of diabetes, heart disease, stroke and colorectal cancers also require less cropland, create less pollution, and have lower GHG emissions 89 and Seafood, which is a healthier animal protein than red meats 91 , has the added advantage that offshore marine aquaculture can have much lower environmental impacts than red meat production Public education and other policies to promote healthier diets thus could help solve two pressing problems.

Pre-harvest losses and losses before retail dominate in lower income countries 93 ; improving agricultural practices, storage and refrigeration can reduce losses between harvest and retail and may pay for themselves.

Post-consumer waste dominates in higher income countries. Combating this more diffuse issue will likely require increased public awareness and innovative policies.

The food system already threatens more wild species than any other human activity, through habitat clearance and fragmentation for farmland, overexploitation of marine and terrestrial species, and widespread pollution.

Rapidly accelerating population sizes and incomes in many tropical countries will lead to great increases in food demand. Numerous agricultural studies in these countries have shown that existing yield gaps can be closed in environmentally efficient manners, and that a major barrier is access to the agronomic practices and inputs required for higher yields.
