Impact Of Climate Change On Ecosystem Pdf – Actions that benefit biodiversity have the potential to support climate action, and some aspects of climate action can support biodiversity.

The IAP Statement on Climate Change and Biodiversity: Linkages and Policy Options includes a section on policy measures that identifies which land-based and marine-based climate policies are beneficial and should be encouraged for biodiversity, and which are not and should not be. therefore you will be disappointed.

Section B of the IAP Statement provides guidance on whether climate measures should be encouraged or rejected based on their impact on biodiversity.

One-third of crops are fed to livestock rather than people, and one-third of food worldwide is lost or wasted. Animal agriculture is a major contributor to global biodiversity loss.

Reductions in meat and dairy consumption and significant reductions in food loss and waste not only significantly reduce greenhouse gas (GHG) emissions, which benefit biodiversity by limiting climate change, but also reduce biodiversity loss and deforestation pressures. land and resources for biodiversity restoration and widespread use of nature-based solutions (NbS).

Thus, for people who make food choices, changing their diet and reducing food loss and waste creates a favorable environment for implementing the other actions outlined below.

A revolutionary change in agriculture is essential to meet the goals of the Paris Agreement and reduce the loss of biodiversity. To achieve this goal, further research on agriculture, which is underfunded compared to other major human activities, should be prioritized. In addition, financial and other incentives should be offered to farmers to support activities that benefit the climate and biodiversity, such as agro-ecological practices.

Because the price of food and other products does not include environmental externalities, many countries benefit from cheap products grown unsustainably in other countries, while others do not benefit from food and have to bear the burden of environmental degradation. Avoiding the importation of unsustainably produced food elsewhere, instead supporting sustainable production regimes and equitable distribution of available food to those who need it, is an essential part of a sustainable and responsible food system.

Deforestation, mainly in the tropics and subtropics, is currently a major cause of global biodiversity loss and local climate change, and has accounted for 5.7 GtCO2 annual emissions over the past decade, accounting for 14% of global CO2 emissions. Reducing deforestation and forest degradation can be achieved by supporting local conservation, providing resources for alternative development pathways, and reducing international demand for deforestation products. Reducing deforestation leads to health benefits by reducing the risk of pathogens transmissible from wildlife to humans in these areas.

Enhancing native ecosystems through network restoration and rehabilitation that facilitates connectivity and species migration improves biodiversity and carbon storage in ecosystems. Natural forests have been estimated to be 40 times better at storing carbon than plantations48. Global forest restoration efforts can sequester 2 GtCO2 per year. Ecologically appropriate restoration of non-forest ecosystems such as savannas and grasslands can increase soil carbon stocks and maintain biodiversity.

It is estimated that more than 600 Gt of protected areas or 20% of the world’s forests49 remain on only 3% of the world’s forests. Conservation and restoration of wetlands has many benefits for amenity, water resources, flood protection, biodiversity and climate. For example, restored birdlands show regrowth of Sphagnum moss species, attracting invertebrates and birds. Existing drained wetlands emit a whole 2 GtCO2 equivalent, which could be saved through restoration.

In addition to restoring and protecting biodiversity and helping to make it more resilient to climate change, many MPAs support climate resilience by protecting coastlines from extreme weather events, for example through coral reefs or mangroves, or by sequestering carbon dioxide in seagrasses. salt water reedy and muddy areas. To be effective, MPAs must be expanded with new investments in their management and enforcement.

Increasing the production of renewable energy should, as far as possible, not have a negative impact on biodiversity. For example, engineers can design offshore wind farms to be biodiversity-friendly and attract underwater species. Techniques include structures where new reefs can grow alongside fish habitats and seagrass habitats.

In general, marine areas where renewable energy technologies are used should be optimized by adopting exclusion zones from other destructive activities such as dredging and dredging, and supporting the deployment of other industries such as mariculture that benefit more from nature. . On Earth, solar farms should not disrupt habitats or impede animal movement56. It is also important for renewable sources to obtain raw materials in a way that causes minimal damage to biodiversity.

Creating corridors (eg planting river corridors and combining conservation efforts) and increasing the coverage of semi-natural ecosystems in intensively used landscapes can facilitate species migration and support ecosystem resilience under climate change. Increasing green spaces in cities is essential for adaptation, as they have a cooling effect and support biodiversity and its connectivity. They contribute to climate change mitigation by sequestering carbon and provide urban residents with the mental and cultural well-being associated with abundant biodiversity.

Tree expansion in ecosystems that naturally expand trees (eg, grasslands, grassy savannas, temperate wetlands) has negative consequences for biodiversity and ecosystem functioning. In the case of wetlands, planting trees can have negative climatic consequences, resulting in drainage and consequently the release of soil carbon stocks.

Planting trees for bioenergy or as long-term carbon sequestration should focus on restoring and expanding native forests, and avoid creating large monoculture plantations that do not support high levels of biodiversity. Simple targets such as “number of trees planted” do not take into account biodiversity, such as tree longevity or management, and can be misleading, leading to policy failure and the misuse of carbon offsets.

What Is Climate Change?

Modeled benefits of bioenergy with carbon capture and storage (eg, using plants to produce energy and fuel while sequestering CO2) are important for mitigating climate change.

However, the scale of some of the modeled deployments would either occupy large amounts of land currently used for food production or adversely affect the amount of land available to conserve or restore natural ecosystems. Policies should also limit the use of fuel pellets and other feedstocks for bioenergy, which can increase pressure on semi-natural ecosystems.

Actions on biodiversity and climate change must recognize, respect and protect the rights and livelihoods of local and traditional users of ecosystems.
