Our land is a critical resource. We rely on it for our food and water, our health and well-being, but it is under pressure humans. Through the energy. We use the ways we live, produce, food and use our land are adding heat trapping gases to the atmosphere, causing global warming and affecting the global climate.
This change in climate is also affecting our land. We are experiencing a loss of biodiversity. Unlike anything, we’ve seen before, and climate change is adding to this pressure. What happens to the land surface affects climate at the same time as as climate affects land.
So what we do now on on the earth surface is crucially important in terms of affecting the future climate over time. Humans have changed the way we use our land. Today we use more than three-quarters of available land for crops.
Pasture cities managed forests and infrastructure. So I think that there’s, a real human dimension to this that this report brings out there’s, an economic dimension. To this there’s, a livelihood dimension to this.
I think it really helps us understand what are the the negative impacts that we are going to continue to have on our society. If we don’t start addressing it. Unsustainable land management practices and the effects of climate change have contributed to widespread land degradation, desertification and challenges to food security.
Land currently absorbs 29 percent of the carbon dioxide that humans emit into the atmosphere, but when land is degraded, it becomes less productive. Restricting what can grow and reducing the soils ability to absorb carbon? Today, 44 percent of methane emissions come from land while 25 to 30 % of all greenhouse gas emissions come from the food system, which is the path that food travels from the farm to consumers tables these emissions contribute to climate change, so plants take up carbon dioxide Where they grow and when they die, they is that carbon dioxide back to the atmosphere.
So anything we do on land like deforestation or reforesting or AG culture changes a carbon in their vegetation and soils so over all those agriculture and forestry activities that we do on land contribute to about 23 % of all greenhouse gas emissions that are caused by humans Emissions of powerful heat trapping gases also arise from agricultural activities related to ruminant animals such as cattle or sheep, and the use of fertilizers in our dryland areas.
Land degradation takes the form of desertification, reducing the ability of ecosystems to provide for us, as they once did, covering over 46 percent of our global land. Drylands are home to 3 billion.
People presented in tradition determine important ecosystem service cotton-poly de la terre, solitary gap day to Tsuchiya Keiichi por la population. Imagine polka meander person deep under the project until the latter.
Imagine echo SAP or Allah says activity la joie de Gras day later voila prove at and party populations, multimatic don’t, say de France activity is a traversable at their song, shouldn’t. We also imagine a dreamer a satyr mama, increased numbers of droughts for longer periods of time will have a devastating impact on already water.
Scarce drylands, decreasing agricultural, outputs and loss of biodiversity in these areas will lead to increased land degradation as climate continues to change. In the future, we expect more extreme events happening more frequently and more intense.
The crops we grow for food also form a crucial part of this land climate connection, with climate change, making a challenging situation. Worse, warming, changing rain patterns and more extreme events such as heat waves, extreme precipitation events or droughts are affecting our food security in some regions.
Crop yields of maize and wheat have already declined in some regions. Climate change has already resulted in lower animal growth rates and livestock productivity caused changes to infestations of pests and diseases and affected food security in drylands.
However, in other regions, particularly at higher latitudes yields of some crops have increased. At the same time, a growing global population with greater spending power and increased demands for animal sourced foods are putting our food systems under pressure.
Our planet is changing and it has impact on our food production, but that’s, not doing only the case. The way we are eating had scenes. We eat a lot of meat and other high calorie dense product, which is not good for our health and also for the planetary health.
The good news is there’s, a great many things we can do to tackle climate change, climate adaptation on land or support food security and avoiding the certification and degradation the land we are already using could feed the world in a change in climate.
It could also provide organic matter or biomass to be turned into renewable energy sources, such as bio, gas or biofuel, which would help to mitigate climate change. But it’s, going to take urgent and far-reaching action from all of us.
Converting large areas of land, for both a forestation and reforestation and for bioenergy crops is one of our options, but there are risks that come with this bioenergy production and a forestation couldn’t race, competition for land affecting food security and land degradation, while Monocultural, bioenergy crops could lead to a further loss of biodiversity.
We can also work towards avoiding reducing or reversing land degradation and desertification. This can be achieved by reducing deforestation and forest degradation and implementing sustainable land management solutions.
This would help to improve soil fertility and carbon storage, as well as agricultural productivity and food security by choosing to consume a balanced diet with more plant-based foods and reducing the 25 to 30 % of food that is lost or wasted.
We can also play a role in reducing emissions from the food system. This would help to improve our health and take pressure off our land, making more land area available for a forestation for bioenergy crops or to restore and preserve natural ecosystems.
Indigenous people across the planet have been living in balance with nature. For many many generations, we have a lot to learn from them. Women have a disproportionate vulnerability to the impacts of climate change and their inclusion in land ownership and management decisions is often constrained.
Empowering women can bring benefits to household food security and sustainable land management. There are many options, but acting now is crucial. Failing to act now will mean fewer land-based options in the future to address our growing land and climate challenges.
If we miss the opportunities and if we go down a path where we don & # 39, t take good care of our land, we & # 39, ll have much fewer options and climate change could be accentuated. Better. Land management can play a role in tackling climate change, but it can’t.
Do it all. So we can’t solve the climate phone without dealing with land, land emissions and and the the uptake of carbon by land. At the same time that we can’t get, we can’t use land to avoid doing things about fossil fuel, industrial emissions, other types of emissions.
It is through an effective mix of policies, markets, institutions and governance across the globe and emissions reductions from all sectors that will limit global warming to one and a half or two degrees Celsius.
It really provides a positive message to say: ok, it’s in our hands to change management of land, nor has to change our diets, and through this changes we can really contribute to climate change mitigation and climate change adaptation.
Protecting our land, our home, is going to take urgent action from all of us.
