Blurring the boundaries: Making way for elephants

Assam is the second largest habitat for Asian Elephants. The systematic habitat destruction and fragmentation on the pretext of agricultural expansion, settlement growth and infrastructural development had rendered the state as hotspot for human-elephant conflicts, claiming as many as 300 elephant lives in the past decade. The diminishing forest...

Trajecting Territories: A Spatial Reconfiguration towards Multipurpose Foodscapes

With an average cheese production of 947 mln kg/year, the dairy industry (in the Netherlands) is responsible for 6.3 % of agricultural/dairy/commodity greenhouse gas (GHG) emissions in Northwestern (NW) Europe. This report brings the production of dairy and its effects on the spatiotemporal and environmental footprints. By performing a material...
