A Research Platform is a research network, focused on a well-defined theme with obvious and high impact at the country level. It requires the participation of experienced researchers from different universities and research institutes. It is led by a coordinating university.

Enhancing the Relationship between People and Pollinators in Eastern India
To create an interdisciplinary participatory research centre at Calcutta University as a flexible model that can be adapted and implemented in other regions

Participatory research
Participatory research focuses on a process of sequential reflection and action, carried out with and by local people rather than on them. Local knowledge and perspectives are not only acknowledged but form the basis for research and planning.
The key difference between participatory and conventional methodologies lies in the location of power in the research process.

Focus on pollination…..
Knowledge gaps:
• Identity of pollinators
• Population abundance and distribution
• Impact of agriculture on pollinators
• Which are effective pollinators of key crops
• How dependent they are on wild plants
• Whether those wild plants are available in the landscape

Calculating pollination service indices
F = density of flowers per m2 H = handling + travel time for one flower.
B = density of bees per m2. L = life time of flowers in hours. Arnob Chatterjee

Which non-crop plants provide resources to pollinators ?
Study is conducted at Balasore district in Odisha in Eastern India. Study sites were chosen across broad landscape (area ~188.35 sq. km) on the basis of the availability of semi-natural habitats. A total of twenty study sites were selected randomly within available semi-natural habitats.

Some feedback from farmers
• The information that there are ‘good’ and ‘bad’ insects is the most valuable information anyone could have. If there is more information like this I would like to know
• The soil is degraded, I would like some technology to help us
• We need improved seeds
• How can we control pests without pesticides?
