Since August 2017, over 740,000 Rohingya refugees have fled atrocities and violence in Myanmar to Cox's Bazar, Bangladesh. There are now one million Rohingya refugees in Cox's Bazar, comprising about 30 percent of the population. This increase, coupled with immediate needs for fuelwood and shelter, has diminished livelihoods due to deforestation and loss of access to land; soil and slope erosion; fuelwood scarcity and associated risks to safety of people collecting fuelwood; increased encroachment and forest degradation; declining water quality, groundwater reserve depletion, and air pollution; decreasing soil quality; and climate vulnerability. To restore cleared forest areas, and improve human and environmental wellbeing, international actors must work with the Government of Bangladesh to implement a long-term forest landscape restoration (FLR) plan for Cox's Bazar. This paper provides a number of recommendations which work towards this goal, focused on: improving efficiency and impact of reforestation investments; improving seedling survival and benefits inside and outside camps; improving disaster resilience and nutrition inside camps; and increasing ecological and social benefits out of camps.

We assessed a 1-ha plot that was planted with 16 100-m2 islets of holm oak Quercus ilex subsp. ballota seedlings near Toledo (Spain) in 1993. In spring 2014 we measured (1) acorn predation and (2) seedling emergence from seeded acorns at different distances from and orientations around the islets with half of the acorns protected to prevent predation, (3) survival of emerged seedlings, and (4) natural tree establishment outside of the planted islets. Most (96.9 %) unprotected acorns were removed or predated. Seedling emergence from protected acorns ranged from 42.9 % on the northern side of the islets to 13.2 % on the southern side, suggesting a less stressful microclimate on the northern side. Survival of naturally established seedlings was 28.6 % by the end of first summer; seedling mortality was chiefly due to drought (45.0 %) and herbivory (35.0 %). Density of emerged seedlings, surviving seedlings after first dry season, and established oaks >1-year old was similar at different distances from the islets. Over the 21 year time period, 58 new oak individuals >1-year old have established (an average of 3.3 established individuals per ha per year) at an average distance of 6.3 ± 5.4 m away from the closest islet. We conclude that initial oak regeneration triggered by small planted islets in Mediterranean abandoned farmland is slowed down by high acorn predation, seedling herbivory, and stressful microclimatic conditions. Regardless, these islets are a viable tool for regeneration of Mediterranean oak woodland. ; Projects from the Spanish Ministry of Science and Education (CGL2010-18312 and CGL2014-53308-P) and the Government of Madrid (S2013/MAE-2719, REMEDINAL-3) are currently providing financial support for this body of research.
