Trees for communities, Mandya, Karnataka, India

Why Trees?

Agrarian regions across Karnataka are increasingly facing compounded environmental and socio-economic stress, and Mandya district stands at the center of this vulnerability. Identified as one of the most climate-sensitive districts in the state, Mandya records a high sensitivity index of 0.200, driven by a combination of environmental exposure and socio-demographic pressures. A significant proportion of marginal and small farmers, coupled with vulnerable populations dependent on natural resources, intensifies the district’s susceptibility to climate variability. Despite being a key agricultural hub, Mandya has only about 4.9% forest cover, indicating limited ecological buffering capacity against climate stress. [1]

The stress is most visibly reflected in the district’s water systems. With 239 villages already identified as vulnerable to drinking water scarcity, Mandya is witnessing a transition from seasonal water shortages to persistent water stress. This is linked to declining groundwater levels, degradation of traditional water bodies, and increasing demand driven by intensive agriculture. [2]

At the same time, Mandya’s identity as the “Sugar Bowl of Karnataka” has led to prolonged monoculture farming practices, particularly sugarcane cultivation, which has placed additional pressure on soil and water resources. Over time, this has contributed to reduced soil fertility, weakened land productivity, and loss of native vegetation, further amplifying ecological imbalance within the Cauvery basin.

In this context, the “Trees for Communities” initiative is designed as a targeted, nature-based response to restore ecological stability and strengthen water security. By planting regionally adapted species across watersheds, lake bunds, and agricultural boundaries, the project directly addresses the core drivers of environmental degradation in the district. Beyond environmental restoration, the initiative will deliver tangible benefits to farming communities. Strategic boundary plantations will support agroforestry practices, providing additional income through fruits, fodder, and timber without impacting crop productivity. At the same time, increased tree cover will improve microclimatic conditions by reducing heat stress, regulating soil moisture, and protecting crops from wind damage thereby enhancing agricultural stability in a semi-arid climate. Importantly  by engaging local farmers, institutions, and vulnerable groups in plantation and maintenance activities, it promotes long-term ownership while generating local employment and livelihood opportunities.

As climate variability continues to intensify across semi-arid regions, initiatives like “Trees for Communities” demonstrate how plantation models can move beyond carbon sequestration to address water security, agricultural sustainability, and rural stability. In districts like Mandya, where environmental and social vulnerabilities intersect, trees are not just ecological assets they are essential infrastructure for sustaining livelihoods and securing the future.

Social impacts

The Trees for Communities project offers significant social benefits for local communities. This project will create multiple employment opportunities for local communities, particularly in activities such as nursery development, sapling preparation, pit digging, plantation, watering, weeding, maintenance, and monitoring. This engagement provides supplementary income while building skills in sustainable land management and ecological restoration. The project places strong emphasis on involving women, promoting inclusive participation and strengthening community ownership.

By restoring degraded landscapes through plantation across farm boundaries, water bodies, and community lands, the project enhances the connection between people and natural resources while encouraging long-term stewardship. It also supports farmers by improving on-farm conditions without affecting existing agricultural practices.

Trees will improve local living conditions by providing shade, reducing heat stress, and enhancing air quality. In addition, they will restore access to essential resources such as fodder, fuelwood, and non-timber forest produce, which are vital for rural households. With improved water availability, better environmental conditions, and diversified livelihood opportunities, the project will strengthen food security and contribute to more stable and climate resilient rural communities.

Ecological & Agricultural Benefits

Agrarian landscapes in Mandya, located within the Cauvery basin, are experiencing ecological degradation driven by soil erosion, declining groundwater levels, and loss of vegetation cover. Through the plantation of regionally adapted species, the project will help restore groundwater recharge, especially around lake bunds and watershed areas, soil stability and reduction in erosion across farmlands and biodiversity, including habitats for birds, pollinators, and small fauna. Improved vegetation cover will strengthen ecosystem functions that are critical for agriculture, particularly in a semi-arid climate. The selected species will contribute to better agricultural outcomes by improving microclimatic conditions such as enhanced soil moisture retention, reduced heat stress on crops, natural windbreak protection and improved soil fertility and organic matter. These improvements will support nearby farmlands, increase productivity, and promote long-term agricultural sustainability while reducing ecological vulnerability.
