Abstract
Many forest protected areas (PAs) are located in developing countries, where forests are a major source of food and fuel. Thus, biodiversity conservation may have unintended consequences on welfare of people in local communities. To explore this issue, we examine the effects of the new PAs in Nepal established during 1995–2003. Using the Nepal Living Standard Survey collected in 1995/1996 and 2003/2004, we evaluate the effects of these new PAs on household consumption, wood collection, and time use. Our estimates suggest that the establishment of PAs reduce the average wood collection by 20–40% compared to the period prior to PA establishment, with greater impact when PAs are strictly managed. We find evidence that households adjust to the new PAs with at least modest shifts to fuel purchased in market but not by using fuel conserving stoves, and that PAs are ineffective when climate makes fuelwood for heating essential or if households are in regions with large dependence on wood as a fuel. Finally, while wood collection reductions could lower household welfare, we find no evidence that PAs trigger either large decreases or increases in total consumption or consumption of food.

According to the World Bank Open Data development indicators (2018) on the terrestrial protected areas, higher income countries have 15.1% of land under protection, and lower income countries have 15.9% area under protection.
Data extracted from the Nepalese census available in IPUMS. The closest substitute for firewood is dung (11.95% in 2001 and 12.55% in 2011).
Category I includes strict nature reserves and wilderness areas, Category II includes national parks, Category III includes natural monuments and natural landmarks, Category IV includes wildlife reserves and wildlife sanctuaries, Category V includes protected landscapes/seascapes, and Category VI includes managed resource protected areas.
We also hypothesized that treatment effects might be higher if households had extensive access to livestock (since dung is a common substitute for wood as a fuel) and in places with many community forests before the PA was established so they had access to an alternative. No results supported those hypotheses, so the analyses are not reported here to reduce tables.
Only 30 households in this panel live near strict PAs, which prevents us from estimating Eq. (2).
