Abstract

Rainfall event on a tree can be partitioned into throughfall, interception loss and stemflow. In this study, stemflow was measured for 39 rainfall events in 5-year-old plantations of 3 trees each, belonging to Morus alba and Grewia optiva in Dehradun, India. Diameter of selected Morus and Grewia trees varies from 7 to 9.3 and 8.12 to 10 cm respectively, whereas height varies from 4 to 4.5 and 5.5 to 6.5 m respectively. The minimum and maximum rainfall events recorded during the study period were 1.01 and 121.70 mm per day respectively. When the rainfall magnitude was less than or equal to 50 mm and more than 50 mm, stemflow volume from Morus was approximately 2.72 and 1.85 fold higher respectively, compared to Grewia. Maximum stemflow volume recorded for Morus and Grewia was 48,065 and 30,633 ml with respect to rainfall magnitude of 109.58 and 121.70 mm respectively. The generation of higher stemflow volume in case of Morus is due to concave orientation of branches and leaves. Results showed that a significant amount of nutrients leached from Grewia and Morus through stemflow process.

Abstract

Trees have been a part of life for centuries in India for sustainable livelihood security. Under the difficult climatic situations, farmers are forced to adopt tree-based systems to secure their income and livelihood. Non-timber forest products (NTFPs) harvesting, collection and processing are creating several employment opportunities in the drought-prone Bundelkhand region of India. This article aims to document the livelihood dependency on trees of farmers, tribals and landless labourers for income generation. Surveys and interviews in Bundelkhand region provided an overview of the dependency of different rural communities on NTFPs such as gum, dona pattal, lac from Butea; brooms, jaggery and baskets from Phoenix; flowers and seeds from mahua; bidi leaves from tendu and sticks from bamboo for sustaining their livelihood. To promote NTFPs-based livelihood enterprises, more emphasis should be given for sustainable harvest, value-addition and marketing.

Abstract

The rising level of carbon dioxide (CO₂) in the atmosphere is a major concern, as scientific evidences show that it is the primary cause of global warming. CO₂ concentration is expected to double by the middle or end of the 21st century, with a temperature rise between 1.5°C and 4.5°C (ref. 1). The importance of agroforestry as a land-use system is receiving wider recognition not only in terms of agricultural sustainability, but also in issues related to carbon sequestration or climate change.
