The Manhattan offices of the Center for Economic and Social Rights, or CESR, do not look like a hotbed of human rights activism. For starters, no one seems to be around, just a rabbit warren of cluttered, but apparently unoccupied, cubicles. Yet these people are busy.

In back, CESR co-founder Roger Normand is meeting with staffer Lucy Mair about their current project, documenting Gaza’s economic decline resulting from border closures between it and Israel and the West Bank since the 1993 Oslo accords.
