Biodiversity preservation in agriculture -

All three organizations have mutual interest in supporting sustainable agriculture, and decided to come together, leveraging the relationships and the work from the carbon program.

This is an opportunity to showcase that we are shifting towards optimizing crop production 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.

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.

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.
