Participatory research and the social learning it supports are increasingly being used to improve forest management. Yet, the participation of women and other marginalized groups is often limited in these processes. This is a serious shortcoming, not only due to concerns for gender and social equity, but also because socially excluded, forest-dependent groups hold specific ecological knowledge, skills and interests that influence prospects for sustainable forest management.

Measuring gender inequality in land ownership is essential for assessing progress in women’s economic empowerment, tracing the impact of progressive laws on actual practice, and monitoring SDG 5 on gender equality. To effectively assess inter-gender (male-female) gaps in land ownership, however, requires multiple measures. We also need to know which women are more likely to own land by tracing intra-gender differences. To date, no study on India has provided a full range of measures on inter-gender inequality in land ownership or focused on intra-gender variations.

Event based rainfall-runoff simulation is very important in water resources management. In this paper, an integrated watershed model considering important hydrological processes has been presented for the event based runoff simulation. Green–Ampt–Mein–Larson model has been used for the estimation of infiltration. For runoff estimation, kinematic wave equations are solved for a channel network using finite-element method. Remotely sensed data have been used for evaluating land use/land cover data.

Polarimetry is a technique for quantitatively estimating the change in polarization in a backscattered electromagnetic signal (in this case a radar signal) with reference to the polarization of the incident signal for estimating the geophysical properties (roughness and dielectric constant) of surface elements. In this study, quadrapole Radarsat-2 data have been utilized for mapping geological elements in Archaean terrain based on their geophysical parameters preserved in the four polarization channels of Radarsat-2 data.

Potential impacts of sustainable intensification and diversification options for agriculture-based livelihoods in Buxa, West Bengal, India, were evaluated using bioeconomic modelling. The baseline scenario involved multiple cropping seasons and a combination of crops on 0.9 ha land-holdings, livestock husbandry, and exploitation of common property resources. With capital costs of Rs.128,180 (US$2293) and annual operating costs of Rs.37,290 (US$667), the net benefit generated (excluding depreciation) was Rs.70,250 (US$1257) annually.

The patterns of urban sprawl over a 20-year period presented in the study indicate unplanned development in the urban agglomerations of Ranchi, Jamshedpur and Dhanbad. The visual interpretation of Landsat (1986, 1991, 1996 and 2001) and IRS-P6 (2005) was used to map land use/land cover and analyse urban sprawl. The saturation of urban areas within municipal limits, along with pressure from the growing population, resulted in the densification of the core urban areas within Dhanbad and Jamshedpur.

A remote-sensing and geographical information sysytem (GIS)-based quantitative methodology for landslide-susceptibility zonation is described in a stepwise manner with its application in the Igo River Basin in the West Siang District of Arunachal Pradesh, Eastern Himalaya, India. Parameters such as geology, physiography, slope angle, slope length, slope aspect, slope type, generic landforms, lineament distance, road distance, drainage distance, altitudinal zones and land cover are used for landslide-susceptibility zonation.

Land use and land cover change, perhaps the most significant anthropogenic disturbance to the environment, mainly due to rapid urbanization/industrialization and large scale agricultural activities. In this paper, an attempt has been made to appraise land use/land cover changes over a century (1914–2007) in the Neyyar River Basin (L=56 km; Area = 483.4 km²) in southern Kerala – a biodiversity hot spot in Peninsular India.

In India the vegetable supply chain has traditionally been fragmented since the majority of growers are smallholders with limited exposure to improved agricultural practices. This study analyzed behavior of 556 vegetable growers in 6 districts of Uttar Pradesh, India, concerning adoption of innovative agricultural practices: crop rotation, green manuring, crop diversification, sorting and grading of produce, and market and price analysis from crop establishment through postharvest and marketing. Most respondents were smallholders.

A number of classification techniques to generate land cover maps from satellite imagery have been proposed but supervised classification with manual selection and delineation of training samples (TSs) continues to be the preferred technique. The current practices of field visits and manual delineation of TSs by visual recognition are highly demanding on both resources and time, with limited utility.
