Abstract

Negative pressures of the industrial world have led to establishment of Brundtland Commission report stating importance of sustainable development for inter and intra generational equity in 1987. Since then sustainable development goals have been marked for poverty alleviation, clean and affordable water, energy security, environment, and agriculture sectors. The global concern of climate change, desertification, and degradation led threats, impact, and resilience for landuse and livelihood is incorporated in sustainable development goals. Sustainable development goals for climate action are met using multiple approaches. Transformative approaches are one such set of approaches for meeting environment challenges for landuse and ecological transient areas or ecotones of agriculture, grasslands, and wetlands affected by human and natural disturbances. Nature based solution falls under transformative approaches and matches the policy efforts on sustainable development goals on decade on restoration and climate positive action for land use and livelihoods. Regeneration potential of natural sites after anthropogenic or natural disturbances is reflected by vegetation health, soil health, and ecology of ecotones. The potential to regenerate is characteristic for ecosystems to revive against anthropogenic and ecological pressures. This facilitates to understand the restoration processes for land degradation and succession changes in an ecosystem. Ecotones are transient ecological regions between different ecosystems and are sensitive sites to study vegetation change due to pressures of globalized world. To detect the changes in vegetation due to climate, desertification, and land degradation on ecotones, we are using NDVI. We are using it for time series analysis for vegetation based changes. We are analyzing vegetation changes over a period of twenty years at a frequency of two weeks. We expect to see changes in the vegetation growth in the presence of anthropogenic and climate impacts.
