Why Trees?

Agricultural regions often face challenges such as groundwater depletion, which can significantly affect crop productivity. This issue is particularly evident in the farmland of Krishnagiri district in Tamil Nadu. In this scenario, agroforestry emerges as a viable solution. Known for its ability to enhance soil fertility, reduce erosion and improve water retention, it can effectively address the challenges in Krishnagiri.

FAO defines agroforestry as, “a dynamic, ecologically based, natural resource management system.” It goes on to say that, “through the integration of trees on farms and in the agricultural land, it diversifies and sustains production for increased social, economic and environmental benefits for land users at all levels. In particular, agroforestry is crucial to smallholder farmers and other rural people because it can enhance their food supply, income and health. Agroforestry systems are multifunctional systems that can provide a wide range of economic, sociocultural and environmental benefits.”^[1]

In our Trees for Farmers® project, we have incorporated a mix of 70% fruit trees and 30% timber trees, carefully selected to ensure biodiversity and maximise benefits for farmers. This approach can lead to a range of positive outcomes. Similarly, integrating shade trees in agroforestry landscapes can regulate temperature, humidity, and nutrient cycling, thereby enhancing ecosystem services even further. Forest Ecology and Management states “trees can aid in sustainable land management by improving soil health and preventing erosion.”^[2]

The root systems of trees play a crucial role in maintaining soil stability, reducing runoff, and enhancing water infiltration, all of which are essential for preserving soil fertility and preventing land degradation. Additionally, tree planting contributes to biodiversity by providing habitats for wildlife, fostering ecosystem resilience in the face of climate change.^[3]

^{Embracing agroforestry practices offers a pathway towards more resilient and productive agricultural systems, ensuring the long-term well-being of both people and the planet.}

Tree Species

We have carefully selected local tree species that are suitable for this region and the climatic conditions. In this tree plantation initiative, we have planted species such as Mango (Mangifera indica), Coconut (Cocos nucifera), Arecanut (Areca catechu), Lemon (Citrus limon), Guava (Psidium guajava), Sapota (Manilkara zapota), Sandal (Santalum album), Mahogany (Swietenia mahagoni), Red Sandal (Pterocarpus santalinus), Jamun (Syzygium cumini), Amla (Phyllanthus emblica), Vengai (Pterocarpus marsupium), Pomegranate (Punica granatum) and Teak (Tectona grandis).

Social Impact

Tree plantation offers numerous benefits that span across multiple aspects.*

We are committed to involving the farmers in our plantation site and generate additional income opportunities for them. They have been sensitised in preparing saplings in the nursery, its transportation, plantation and maintenance. The local communities also earn added income from the plantation produce. They can also supplement their income from fruits and timber once our trees mature. We believe in empowering women by generating employment opportunities for them as well. Inclusivity is a key commitment across all our tree plantation sites.

Tree plantation can help regulate the natural water cycle and improve water quality. This will benefit both the farmers and the local community. When water from rainfall and other sources soaks into the ground and refills underground sources, it is known as groundwater recharge. This will ensure that the community has enough water for drinking, agriculture and other uses. Planting trees in farmland will help increase the agricultural productivity of the local farmers by reducing soil erosion and improving the overall soil quality.

Trees play a key role in absorption of carbon dioxide from the atmosphere. A mature tree can absorb up to 20 kg of CO2 each year. Planting trees keeps the temperature cool and reduces atmospheric stressors.
