Since ages agroforestry has been known as a traditional land-use system in India. The multivarious benefits and services generated are recognized as a tool to improve the livelihood status of farmers. Commercial agroforestry gained momentum in the regions where it got support from industry and assured market facilities. However, lack of policy initiatives and strict trade regulations has not supported wide adoption of agroforestry. Though prominent agroforestry models are being developed in different parts of the country, there is no clear-cut mechanism from seed procurement to marketing of the products. In this context, the National Agroforestry Policy, 2014 came in limelight to address the issues of quality planting material, tree insurance, restrictions on transit and harvesting, marketing of agroforestry produce, research and extension. This article links highlights of the policy to existing successful ground-level schemes and the challenges to focus on agroforestry not only as a successful land-use system, but also to utilize its full potential in the economic development of the country.Keywords

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.Keywords

Wood specific gravity (WSG) is an important parameter in allometric equations for accurate estimation of C-sequestration and other functional properties of a tree. However, WSG of many tree species especially of arid and semi-arid regions is poorly reported. Further, identifying indirect methods for determination of stem WSG from branches may be rapid and relatively easy. The present study determined WSG of stem and branches of 21 tree species in the hot semi-arid region of Western India. Three individual trees from each species were randomly selected and sampled for determination of WSG of stem, primary and secondary branch. WSG varied significantly among the species (F = 42.83, P < 0.001) and sampling locations (stem and branches) (F = 29.43, P < 0.001). In stem (at DBH), it ranged from 0.42 ± 0.04 to 0.74 ± 0.03 among the species while within an individual tree it varied in order of stem > primary branch > secondary branch in most species. WSG of stem and branches showed linear relationship and branches were found a good predictor of stem WSG (R2 > 0.83).Keywords

Agroforestry is one of the most promising options for climate change mitigation through carbon sequestration. However, carbon sequestered in agroforestry system depends on various factors like type of tree species, tree density, system age, soil and climate. One of the most important factors for enhancing carbon sequestration per unit land is tree density. Hardwickia binata Roxb. has been reported as suitable agroforestry tree species with multiple benefits in arid and semi-arid region, however, the role and impact of tree density in carbon sequestration is poorly reported. This study estimated impact of tree density (D1 = 333 tree ha-1 and D2 = 666 tree ha-1) on carbon sequestration potential of 30-year-old H. binata Roxb. + Cenchrus setigerus silvipasture system in hot semiarid region of Rajasthan. The carbon sequestered in tree biomass was estimated by reported allometric equations, whereas in soil it was determined by Walkley and Black method. Results showed significant impact of tree density on carbon sequestration per unit tree and per hectare land. The average biomass carbon sequestered by a tree was significantly more (44.5%) in low density (D1) compared to high density (D1) system. However, total biomass carbon sequestered per hectare land was significantly more (40.8%) in high density system (31.6 ± 12.6 Mg C ha-1. Carbon sequestered in soil organic matter was higher in both D1 and D1 systems compared to control (sole Cenchrus setigerus field). It ranged from 19.93 ± 0.31 Mg C ha-1 in control to 22.94 ± 0.65 Mg C ha-1 and 23.25 ± 0.78 Mg C ha-1 in D1 and D2 respectively. The total carbon sequestered (below and above ground tree biomass and soil organic carbon) was in the order D2 > D1 > control.Keywords

As the childs dentition changes from primary to permanent dentition there are a number of changes that happens in the oral cavity of the child. This intermediate stage of transition is known as Mixed dentition stage and lasts from 6 years to 12 years. The identification and measurement of these changes is of great importance in preventing, managing and treating future dental as well as skeletal malocclusions. Over the years several tests and analysis have been done to analyse these changes. The aim of this paper is to analyse the existing literature on various mixed dentition analysis and also to spot light on the recently developed mixed dentitons and primary dentition analysis.Keywords

One in seven of the population of the world is highly anxious about undergoing dental treatment and requires careful and considerate management by dental practitioners. The interaction between the dentist, dental health team and the patient can reveal the presence of anxiety, fear, and phobia. In such situations, subjective evaluation by interviews and self-reporting on fear and anxiety scales and objective assessment of blood pressure, pulse rate, pulse oximetry, finger temperature, and galvanic skin response can greatly enhance the diagnosis and enable categorization of these individuals as mildly, moderately, or highly anxious or dental phobics Formulating acceptable evidence-based therapies for children is essential, or else they can be a considerable source of stress for the dentist.Keywords

Numerous studies have underlined the benefits of cultural services from different landscapes and acknowledge the non-material benefits linking society and nature. However, cultural services from agroforestry have not been reported. Therefore, the present study was conducted in multifunctional agroforestry (MFA) comprised of 24 tree species and 8 intercrops established at the Forest College and Research Institute, Mettupalayam, Tamil Nadu, India. Four workshops were conducted and a total of 105 respondents were asked to fill two sets of questionnaires regarding their perception of cultural ecosystem services in MFA. Among the selected components, education and scientific knowledge (0.90) ranked first, followed by relaxation (0.86) and walking (0.84). Results from principal component analysis revealed that three components, viz. relaxation, education and scientific knowledge, and inspiration accounted for 56.60% of the variance. Respondents’ willingness to pay was Rs 33/visit on an average and multiple regression analysis indicated that the MFA model was a good fit (R2 = 0.79) for agroforestry tourism. The results indicate that MFA provides scope for agroforestry tourism, which will be an additional source of income for small and marginal-scale farmers.Keywords

Agroforestry is widely recognized for its role in climate change mitigation and adaptation. However, carbon sequestration and a marketable carbon value of smallholder agroforestry systems in India are poorly documented. Therefore, the present study was carried out to quantify carbon stock in a circular-shaped multifunctional agroforestry (MFA) divided into four equal quadrats. It comprises 24 different tree species and 8 intercrops, mainly established to provide daily income to small and marginal farmers. A nondestructive method was used to assess biomass carbon stock. Soil core samples collected from 0 to 60 cm depth were analysed to quantify soil organic carbon (SOC) stock. Results revealed significantly higher biomass and carbon stock in the following order: Neolamarckia cadamba > Melia dubia > Lagerstroemia parviflora > Dalbergia latifolia > Tectona grandis. Duncan’s multiple range test revealed significant differences in the multi-utility circles (P < 0.001). The total change in SOC stock was 11.55 Mg quadrat–1, but the difference was insignificant in different soil depths. The results indicated that the total carbon sequestration and CO2e from vegetation were 2.23 and 9.23 tonnes respectively. Similarly, CO2e from the soil were 42.37 Mg quadrat–1 respectively; the highest contributions were from quadrat II and quadrat IV of MFA. By taking into account profitability and incentives to smallholder farmers, the total marketable carbon revenue of MFA was calculated as US$ 206.40Keywords

This study deals with the oxygen production potential of India taking baseline data from ISFR 2019. The Indian forests have an oxygen production potential of 7896.14 million tonnes (mt) and the annual potential was 28.04 mt yr–1 for 2019. Considering oxygen production potential of the top 10 tree species from forests and those outside forests, Shorea robusta (Sal) and Mangifera indica (Mango) ranked first, i.e. 657.87 and 214.39 mt respectively. The fast-growing agroforestry tree species exhibit a net oxygen production rate in the range of 1.03–34.15 tonnes ha–1 yr–1. Bamboo being a fast-growing and higher biomass-producing species showed oxygen production of 27.38 mt yr–1. Overall this provides huge scope for establishing oxyparks in IndiaKeywords
