1. Efficient and effective use of available natural resources especially land and water resources.

2. Sustainable and integrated management of resources to ensure coordinated use with little wastage.

3. Optimization of the 3Rs (Reduction, Reuse and Recycle) in all production and consumption systems.

Although these two phenomenons ( biodiversity loss and climate change) basically come through anthropogenic activities, both can be alleviated by natural means. These green/nature-based methods can be implemented at the global, regional, and local levels. These environmental rehabilitation projects are maybe starting from creating deep awareness for the global community, mass planting trees, install environmentally sound industries, promote green economy.

For aquatic ecosystems a relatively simple means of mitigating climate change and also land use impacts is to have a functioning riparian zone. Shading can lower, for example, in-stream water temperatures by several degrees (e.g. Johnson and Almlöf, 2016). Riparian habitats can also function as nutrient sinks, decreasing nutrient inputs and eutrophication, as well as harbour relatively high species diversity and unique food webs.

1.) Stand down all militaries...so you have the funds to do something substantial, and make peace with your neighbors, and settle any territorial controversies. Does not make ANY sense in having nuclear bombs aimed at each other, when you are trying to fix the environment for both of you? India is spending $65 billion a year, and increasing at 7% a year right now, that could be used for the environment, fighting the pandemic, clean water, a free solar panel on every roof, housing for all, a free composting toilet for those without sewer systems, etc.

2.) Buy the marginal arid grazing lands and marginal desert and abandoned farm lands... around the world. So in India, that would be in the western parts around the Thar desert, and pay the former grazers and former farmers, to replant the local native perennial grasses, to put back some cover, cool the climate and sequester carbon in the soil, and increase the rainfall of the area. See http://www.ecoseeds.com/cool.html

3.) While planting the grasses, replant the local native Pseudomonas host plants...that actually create the rainfall for the planet, that the Indus Valley people chopped down to fire the bricks to build their 1,000 cities--from where is now Pakistan 3,500 years ago--then they had to abandon all of their 1,000 cities when the rain stopped.

Nature cannot eliminate all the pollution gases thrown out by humans. There can't be any solution to climate change unless we change our polluting ways.

A couple of months ago I gave a webinar about NBS in cities, organized by the Global Platform of Sustainable Cities (GPSC). Perhaps this is of interest and useful in answering your question?

Dealing with a changing climate and ongoing urbanization including loss of forest and natural land; there has been a further call for nature-based solutions in the development of urban areas. For achieving a healthy and livable city we need to consider a city that provides ecosystem services and a healthy natural environment, thereby offering a range of social, ecological and economic benefits. After all, as people we are part of urban ecosystem or "ecopolis". This webinar discusses: - The city in its natural landscape. - What are nature-based solutions? - Water-Sensitive urban design. - Nature-Base Solution for developing climate resilient pathways. - Applications in practice: case of São Paulo.
