Household Dependency on Buffer Zone Community Forest and its Implication for Management of Chitwan National Park, Nepal

Conservation of biodiversity in Protected Areas will be more challenging if local communities are heavily dependent on them for various forest products and subsistence needs. Thus this study sought to identify the demographic and socioeconomic variable that influence forest dependency exploring the relationship of forest dependency and household characteristics of the households of the Panbari Buffer Zone Community Forest User Group of Chitwan National Park, Nepal. A sample of 130 households was randomly selected for the household survey using stratified random sampling and collected was analyzed using logistic regression model. Logistic regression result indicate that wealth status of the poor household, household family size, livestock population, agricultural income and education are the five major determinants of forest dependency in Panbari Buffer Zone Community Forest. Policy interventions to ensure long-term success of landscape-level conservation of Chitwan National Park are needed to decrease dependence on forest resources expanding educational and training opportunities; and the policy measures that aim at increasing agriculture income, generating off-farm employment opportunities, supply of the alternatives of fuel wood energy and adopting agrisilvicultural system for the supply of fodder for the livestock.


Introduction
Forest dependency of the human beings is a multifaceted phenomenon due to the fact that forests provide a diverse stream of benefits to humans such as timber, fuel wood, fodder, non-timber forest products (NTFPs), recreational experience as a direct benefits and also depends upon forests indirectly for things such as biodiversity, air and water quality, carbon sequestration, and other ecological services (Beckley 1998, Masozera 2002, Adam and EL Tayeb 2014). In many developing countries, the households' dependency on the forest resources has motivated the policy makers to decentralize the approach of forest management to the evolution of community forestry (CF) as the dominant forest management strategy (Rai et al. 2016). CF has a significant contribution to the improvement of environmental conditions in degraded areas and enhancing the livelihoods of forest dependent communities ( Buffer Zone Community Forest (BZCF) is also the community-based forest management, which involves the forest areas and the forest users around the protected areas that aim the conservation of biodiversity and the sustainable use of natural resources by the local people living nearby areas. Fourth amendment (1993) to the National Park and wildlife Conservation Act, 1973 brought the concept of Buffer Zone in Nepal that gradually changed its policies for inclusion of local people in PAs management, bio-diversity conservation and community development in the periphery of PAs. One of the major objectives to bring the concept of buffer zone management in Nepal was to develop a partnership between the park and the local people in biodiversity conservation with the forest resource use (CNP 2013). In Nepal, forest resource use and the conservation of the National Parks are well defined by National Parks and Wildlife Conservation Act of 1973; and Buffer Zone Management Regulation, 1996 and states that the ownership of the land of Buffer zone Community forest belongs to the Government of Nepal giving only the use rights to the buffer zone user groups (HMGN 1996). Moreover, these regulations enjoined participation and empowerment of local people for the conservation, management, and use of natural resources; and have tried to address the problems of people whose livelihoods are adversely affected by the parks/ reserves through community development. But, at present, BZCF is considered as additional habitat for wild animals that is viewed from the point of wildlife conservation aspect in which the programs directed towards the conservation of wildlife (CNP 2013) and gradually supporting the local people to meet their daily basic needs of fuel wood, fodder, grasses and other forest resources (Bhusal 2014).
Research studies related to the household surveys have revealed the higher dependency of the rural poor people on forest resources due to the fact that greater proportion of their total income comes from forest resources collection (Sunderlin et al. 2005, Bhandari and Uibrig 2008, Sapkota and Odén 2008). Similarly, Odihi (2003) noted that one cause of deforestation was the lack of alternative energy sources and high-profit margins from the fuel wood economy. Moreover, forests are promoted to improve the well-being of local communities (Elands et al. 2004), and large numbers of poor people have occupied extensive forest areas for their livelihoods for the use of forest resources in the tropics (Wunder 2001). In the context of Nepal, forests are intently related to the survival of the rural poor that fulfill the basic needs. Moreover, 65 percent of households are dependent on the forest resources for the collection of the firewood; and 43 percent households collect the fodder from the forest to feed their livestock's (CBS 2011). The procurement of fuel wood for cooking and house heating accounts for 83% of the energy consumption and the dependency on timber and NTFPs exceeds 95% (Gautam 2006). Livestock rearing is highly reliable on the grazing and fodder collection which is traditionally practiced (FAO 2010). However, household dependency on the forest resources has an adverse impact on biodiversity; and extreme pressure on these resources which has resulted in the declination of the conservation and preservation of the resources (Parker and Thapa 2012). Therefore, preservation and conservation of biodiversity of protected areas has become complex and challenging in the sense that the local people are more dependent on forest resources for energy, agriculture, nutritional, medicinal, and other subsistence needs (Adam and EL Tayeb 2014; Jain  and Sajjad 2015 citing in Bahuguna 2000). So, governments are often strapped for resources to protect, conserve and sustainably use natural resources. In such situations, buffer zone with some level of use of forest resources from the protected areas can play an important role in ensuring natural resource conservation and develop positive response towards the conservation of protected areas. Several studies have indicated that forest dependency varies across households and these households depend more or less on forest resources depending on their demographic and socioeconomic characteristics (Gunatilake 1998 ERA (2004) incorporates that the environmental awareness classes taken at the local schools of the Buffer Zone areas had a positive impact and due to this awareness program, cleanliness in the household and community environment was improved; and households had prioritized for keeping a small size of livestock, stall feeding practice, tree plantation and bio-gas installation.
Among many protected areas system in Nepal, Chitwan National Park (CNP) as the first Protected Area of Nepal has utilized buffer zone programs as a key conservation and management (Dhakal and Thapa 2015). A forest area of 10,886.76 hectares is handed over to the 20 BZCF user groups as a BZCF in CNP which has benefited a population of 0.2 million people of 37,503 households (CNP 2015). Though, the case for a buffer zone approach was evident in CNP as threats to biodiversity conservation has continued to exist due to the traditional high forest resource dependency of local people on CNP and its BZCF (Budhathoki 2005, CNP 2013, Dhakal and Thapa 2015. Five years management plan of CNP and its Buffer Zone has clearly stated that the lack or inadequacy of proper linkages between research study related to household socioeconomic characteristics and management has failed to address the high forest dependency of the local people in the CNP and its buffer zone (CNP 2013). Therefore it is essential to determine and examine the household socioeconomic variables of the local people living around the CNP with respect to the forest dependency so that management programs of buffer zone can be effectively implemented.
Thus, understanding the household different characteristics and relationships among local communities and their resource use patterns is supportive in designing management plans for the community-based management programs as well as to develop the conservation and development strategies (Gunatilake 1998, Masozera and Alavalapati 2004, Lepetu 2007, Lepetu et al. 2009, Jain and Sajjad 2015. In absence of the information about household forest dependency, any steps in the management of the buffer zone will have unwanted consequences and may constrain the positive outcome. Still needed, however, is a better understanding of how household dependency on the forest resources is associated with different demographic and socioeconomic variables which tend to solve the problem of the community level decision-making and, ultimately, landscape outcomes. Therefore, the identification of the factors affecting forest dependency is an initial step towards devising policies that are beneficial for an equitable sustainable resource management and conservation of biodiversity. Here, we describe the results of a household survey of Panbari Buffer Zone Community Forest User Group members of CNP in southern Nepal (Fig. 1). Our first research objective sought to identify the demographic and socioeconomic variable that influences supportive dependency on forest resources. Our second research objective explored the relationship of forest resource use (dependency) and household characteristics with the better implications for the conservation of Chitwan National Park.

Study area
Chitwan National Park, established in 1973, is a UNESCO-designated World Heritage Site. CNP is especially renowned for its protection of Asian onehorned rhinoceros (Rhinoceros unicornis), Royal Bengal tiger (Panthera tigris), Gharial crocodile (Gavialis gangeticus) and Asian elephants (Elephas maximus). CNP and its Buffer Zone is situated in southern part of Central Nepal which spreads over 4 districts: Chitwan, Nawalparasi, Parsa and Makawanpur having the area of 932 km2 and an area of 750 km2 has surrounded the park as its buffer zone (CNP 2013, DNPWC 2016).
For this study, the entire area of the Panbari Buffer Zone Community Forest (PBZCF) of CNP is considered (fig 1). PBZCF lies in the Naya Belhani Village Development Committee (VDC) of Nawalparasi district. Altogether 849 households consisting population of 4346 are involved in the management of the PBZCF, managing 499 hectares of forest (CNP 2015, PBZCF 2015). Its altitude ranges from 175-250 meter from the mean sea level and the average temperature is 240 C with a mean annual rainfall of 2150 mm. Naryani River is the main river system in this area with some wetlands, which provides the better home for many migratory birds and one-horned rhinoceros. Furthermore in 1978, households of 469 retired army were shifted in this area from different parts of the Nepal and lived here after clearing 56 hectare of forest land and named some part of the village as "Bhuputol" (PBZCF 2015). However, till now the Government of Nepal has not legally provided this land to these household and indicated this land area as forest encroached land. Due to this, more than half of the households are legally landless and shows that they may be more dependent on PBZCF for their livelihood. A majority of the households were found migrants from various parts of the country and densely distributed. Furthermore, this PBZCF user group has employed two forest watchers with the responsibility to look after the forest.

Data Collection
This study site: Panbari Buffer Zone Community Forest User Group (PBZCFUG) was selected based on three criteria i) The operational plan of this PBZCF was recently revised in 2015: 5 years operational plan approved by CNP and it was first handed over to User groups on 2009; ii) A socially complex site, but secure enough to carry out fieldwork; iii) Large numbers of forest-dependent households. The target population for this study is the user group members of PBZCF. In selecting the households to be sampled, stratified random sampling was used. To determine the relative economic status of each household of the PBZCFUG, a wealth ranking based on PRA technique was organized. The empirical validity of this method as a means of socioeconomic stratification of households has already been tested in CF-related research in Nepal (Richards et al. 1999). Wealth ranking of the total households was conducted with the user committee members along with the other key persons viz. school teachers and VDC leaders, which was involved in their respective settlements for this exercise. This type of category was also used by Dhakal  Based on the wealth ranking, a stratified random sampling was performed to draw the sample households for household survey in order to secure the representation of each economic class: rich, medium, poor. According to Neuman (1994), more than 10% sampling intensity for the moderately large population is valid for the social studies. Therefore, a total of 130 households: 30 rich, 59 medium and 41 poor households were randomly chosen at 15% sampling intensity and interviewed.
The primary data were collected through face-to-face household interview. A structured and semistructured questionnaire was used for household survey in order to gather the quantitative as well as qualitative information. A questionnaire was prepared in English and questions were orally translated into the Nepali language while taking the interview of the respondents. For the reliability of the information of the households of PBZCF, pre-testing of the questionnaire was carried out before the household survey. Interview in most cases was conducted with the household head. In the absence of household head, other household members who were familiar with the household information with the forest resource use were selected for the interview.
Questions were asked to obtain information on households' size; distance from the forests; residency of years; forest resource collection time and collected quantity; benefits of Buffer zone program; time contributed for different forest management activities; landholdings; production of different agriculture crops; number of livestock; major income sources; caste and ethnicity; and other issues related to household level of wildlife conflict. In addition, secondary data was collected from the BZCF records and government documents respectively.

Forest dependency model specifications
The concept of forest dependency is focused on the degree of concentration of a particular forest based livelihood in a particular area (Illukpitiya 2006). Differences in forest dependency of the local people arises due to disparities in the socioeconomic conditions, values, beliefs, goals and preferences of the members of that community (Adhikari et al. 2004) and will not remain static over time, resulting in changing resource dependency over time (Cavendish 2000). Based on methods used by other researchers described previously, the proportion of income from the forest resource was used to estimate forest dependency. This relative value of resource dependency was used since it is easily calculated from information readily available from respondents, provides an acceptable indication of dependency and has been used in other studies such as by (Gunatilake 1998

Forest income
Forest income as the benefit from the forest was calculated as the sum of the benefits got from forest management; forest products collection, buffer zone program or PBZCFUG support; and other benefits such as training and workshop allowance. Forest products collected from the forest were recorded for each household during the household survey. The collected forest products from the PBZCF were firewood, fodder, thatch grass, Sal (Shorea robusta) leaf, mushroom and sand/gravel/stone. The income was computed annually for marketable forest products-including firewood, sand/gravel/stone by multiplying each item's quantity by its market price. Time cost was taken into consideration for the calculation of income from non-traded forest products such as fodder for livestock, thatch grass, mushrooms and sal leaves. Following Rai et al. (2016), the value of time was estimated under two scenarios: (i) the market wage rate and (ii) the opportunity cost of time with the paid work. The time for each forest products collection was collected from the interview of each household. The opportunity cost of time may vary across the individuals within society. Therefore, in this calculation the opportunity cost of time was assumed to be 47% of the market wage rate based on the estimates of Scarborough (2013 &. According to HMGN (1992) and ILO (2007), the standard amount of working hours per week is 48 and per day working hour is 8 hours with 1 day rest in a week. In addition, market wage rate of Nawalparasi district of the year 2016 was NRs 440. Thus the forest products collection time cost, as the income from the non-traded forest products was calculated by multiplying the 47 percent of the wage rate with total forest products collection days.

Farm income
Farm income includes the income from the agricultural crops and the livestock. Agricultural income includes cultivation of crops for purposes of both household consumption and selling. The quantity of crop yield was obtained from individual households through face-to-face interviews. In the absence of the local market, the price of each agricultural product was obtained from price as reported by the respondents. The annual household income from agriculture was computed as the product of the quantity of the agriculture crop yield and respective prices. Furthermore, the livestock income included the sales of the livestock and income from the products of livestock such as milk, egg.

Off farm income
Off farm income included the incomes from the business, salaried jobs, pension, wage labor, remittances. Wage labor in the study area is mostly in the agricultural activities. The wage rate and a number of working days/hours reported by the respondents are used in the estimation. Income from salaried jobs, pension, business, and remittances was also obtained from the respondents' interview.  (1995) has stated that the logistic function, as a binary dependent variable is analytically convenient that approximates the normal distribution satisfactorily. Nepal Government does not have any base for assigning the forest dependency index. Therefore, the dependency index of the sampled households was divided at the median (Lepetu et al. 2009). Although there are a few circumstances in this study that the forest dependency index ranges 40% and beyond, the majority of cases are clustered at the lower end of the scale, with most of them falling below 5%. These high values for only a few cases have a significant effect on the mean but little or no effect on the median, making the median a better indication of central tendency in this example (Mertler and Vannatta 2005).
Peng and So (2002) mentioned that the logistic regression is an alternative technique to overcome the limitations of the OLS regression in handling dichotomous outcomes (high forest dependency and low forest dependency) whose probability is related to the explanatory variables that are postulated to influence the outcome. Thus the forest dependency index as the dependent variable in the logistic regression model was first converted to a dichotomous dummy variable by separating the ''supportive'' dependency index scores from the ''unsupportive'' scores at the median. Due to the dichotomous dummy variables of the forest dependency, the variable was assigned a value of "1" (supportive) if the household forest dependency index is ≥ 0.05 and a value of "0" (unsupportive) if the household forest dependency index is less than 0.05.
The model used to estimate forest dependency is specified as follows ln[P i / (1− P i )]= β 0 + β 1 X 1i + β 2 X 2i +...+ β k X ki Where, subscript i denotes the i-th observation in the sample; P is the probability of the outcome; β 0 is the intercept term; and β 1 , β 2 , ……, β k are the coefficients associated with each explanatory variable X 1 , X 2 , ..., X k. In this study, the explanatory variables used to explain household's dependency on forest resources include education, age, gender, wealth status, distance to the forest from the house, household size, agriculture income, livestock unit, landholding size, transaction cost of forest management, crop raid and livestock depredation by wildlife (Table 1). Therefore, before presenting the results of estimation, a brief description of each explanatory variable and expected theoretical relationship to forest dependency is provided below. Gender: In the case of the rural areas of Nepal, male members of the community have more control over the resources and often enjoy greater freedom with better income earning opportunities (Adhikari et al. 2004). This results that males contribute significantly to forest resource collection than females. In addition, the collection time of the forest products such as fodder, fuel wood, thatch grass and some NTFPs in PBZCF is only limited to 2 months in a year and there is a danger of wild animals in these areas (PBZCF 2015). In such situations, men are more likely to take the risk of going into the forest when compared with women (Lepetu et al. 2009). It is therefore assumed that the male-headed households derive more forest products than female-headed households.
Age: Age is not the limiting factor for the collection of forest products. Younger villagers in the rural community are less dependent on the forest resources because of their willingness to explore opportunities outside the forest and have an easier time compared to their elders in finding jobs outside of forest (Jain and Sajjad 2015). Furthermore, the age of the household head is also correlated with household's experience in managing common resources and has a better experience in local resources management and quality harvesting than younger ones (Adhikari et al. 2004 Reddy and Chakravarty (1999) argued that the poor have less land and greater share of the forest income makes them more dependent on forests resources, and community-based forest management is attractive for the poor households (Khanal 2001). As such, it is hypothesized that poor households may be associated with the increased forest dependency.
Household size (HHS): Families with more household members have more mouths to feed and tend to extract more forest resources for their livelihood (Gunatilake 1998, Hegde and Enters 2000, Jain and Sajjad 2015). The increase in the household members increases the fuel wood demand. In fact, a larger household extracts more forest resources due to more labor availability to collect and gather various forest resources (Adhikari et al. 2004). In addition, higher unemployment on the periphery of the forest tends the large families to depend more on forest resources in order to increase their income or to meet their subsistence needs. Hence, the household size may be significantly and positively correlated with the forest dependency.
Distance: The PBZCF distance from the respondent's household was found out from the GPS coordinates recorded at the time of the household survey. For this purpose GPS receiver: Garmin GPS Map 64S was used to navigate the location of the respondent household. Again these locations were analyzed in ARCMAP 10 to find the distance between the PBZCF boundary and the household. Households near to the forest area are more probable to collect more forest resources from the community-based forests and reverse was true for the distant users because of the difficulties in carrying harvested products (Adhikari, 2003;Sapkota and Odén, 2008). Further, Varughese and Ostrom (2001) argued that the rural households nearby the forest have more secure and accessible supply of forest products nevertheless they are controlled by rules and regulations. Therefore the distance between the forest and the household may decrease the utilization of forest products.
Landholding size (LHS): During the field survey, the land area was asked in Nepali standard unit "katha" and later converted into hectares. In general, households holding more own land are less dependent on the forest resources of the Protected Areas because they possess alternative means to maintain their livelihood through agriculture (Gunatilake 1998). Thus, landholding size is expected to have a negative relationship to forest dependency.
Agriculture income (TAGRINC): Adam and EL Tayeb (2014), Gunatilake (1998) and Masozera and Alavalapati (2004) showed that higher agriculture productivity and agriculture income result in less extraction of forest resources. This is expected because households would rather prefer to work on their farms than the collection of the forest products. Therefore, it hypothesized that the agriculture income is significant and negatively correlated with forest dependency.  (Adhikari and Lovett 2006). The same methodology used for the calculation of forest income was applied to find the opportunity cost of time for calculating the transaction cost. Adhikari (2003b) found that households who spent more time on forest management and forest related decisionmaking activities appear to obtain more forest product income. Therefore it is assumed that the transaction cost of the forest management has a positive effect on the collection of forest resources.
In PBZCFUG 23.08, 45.38 and 31.54 % of the respondents were categorized as rich, medium and poor respectively. Moreover, the average annual income of the rich, medium and poor household was US$ 7013.44, 3254.01 and 1866.798respectively. In addition, the average forest dependency index of rich, medium and poor was 0.01, 0.06 and 0.35 respectively. The respondents of the PBZCFUG had different level of forest income with different quantity of forest products collection among different wealth groups. The average firewood collection of rich, medium and poor households was 555, 1401 and 5190 kg per year respectively. In addition, rich, medium and poor households respectively collected annual average of 724, 2522 and 5431 kg of fodder. Furthermore, the study of Richards et al. (2003) showed that per capita consumption of firewood in Nepal is 700 kg per year but annual firewood consumption of poor household of PBZCFUG was 807 kg per capita. Moreover, the annual average forest income and agriculture income of the rich, medium and poor households from the PBZCF were US$ 71, 193 and 646; and US$ 618, 351 and 275 respectively. Furthermore, the average land area owned by the rich, medium and poor was 0.57, 0.26 and .08 hectares respectively

Forest Dependency
Based on the data collected, only 48 % of the households in the PBZCFUG were considered highly dependent on forest resources. The mean number of hours spent by the households in the forest resource collection was 15.7 hours per week. Moreover, firewood and fodder were the main forest products collected from the PBZCF by the forest user members. Respondent households collected annually an average of 2400 kg and 3024 kg of firewood and fodder respectively. This shows that the annual consumption of firewood per capita was 420.4 kg.
Besides firewood and fodder, other forest resources such as thatch grass, mushroom and Sal leafs were extracted in a very low quantity by the households of PBZCFUG. The average annual forest income of the household was US$ 308 and this forest income has shared in 14.1 % of their total income on the households of PBZCFUG.
Results of the model explaining the forest dependency are presented in Table 3. For the estimation of the logistic regression analysis, 130 sampled forest user members of PBCF were taken as a total number of observations. In addition, the parameters estimated for the model were eventuated at 1% and 5% level of significance.  This model has shown that Wealth (wealth status) of the household is highly significant to the forest dependency. The high positive coefficient value for wealth status "poor" suggested that the worse-off households collect higher amounts of fuel-wood from the forest because they cannot afford the substitutes of fuel wood such as LP gas, bio-gas and electricity. Moreover, poor households should also depend on forest fodder to feed the livestock because of the less availability of own land. The finding is similar to that of Fonta et al. (2011), that found the "poor status" of the household was significant (P<.01) and had the positive relationship with the forest income in the rural households of the Cross River Community Forest, Nigeria. Sapkota and Odén (2008) found that the rich households are statistically significant and have negative relationship on the collection of the fuel wood in the Shankarnagar CF of Rupandehi district of Nepal. This finding has contradiction over Adhikari et al. (2004) findings, as that finding showed that the rich households had significant positive relation with the fuel wood and fodder collection in the mid-hills community forests of Kabhre Palanchok and Sindhu Palchowk district of Nepal which indicates that resource usage from CF is directly proportional to private endowments.
The variable household size (HHS) has a positive relationship and significant with forest dependency. This suggests that large families are more dependent on forest resources. This is due to the fact that limited income opportunities and higher unemployment in the rural areas tends large families to depend more on forest resources to fulfill their basic needs. Moreover, to support large family members of the household, they have to increase their earnings in addition to main livelihood activities so that the quantity of production may rise due to more number of household members engaging in forest resource collection.  Baral and Heinen (2007) found that the household size had the negative relationship with the forest dependency in the Bardia National Park and Suklaphata Wildlife Reserve of Nepal: however, since the relation is insignificant, it cannot possibly be a contradiction.
The variable agricultural income (TAGRINC) shows a negative relationship with forest dependency. This implies that households with high total agriculture income are less dependent on forest resources due to the fact that most of the grasses and fodder for livestock consumption is derived from the agriculture land. Furthermore, agroforestry system reduces the gathering of forest resources and provides both fodder and firewood for the rural communities. Thus, agriculture reduces quantity of extraction of forest resources and its income, by competing for and taking over labor as well as time that would otherwise be invested for forest related activities. Moreover, this finding is similar to the finding of Gunatilake (1998) where the significance of agriculture income was found to have a negative impact on forest dependency due to the diversified household income from agriculture as the source of livelihood. As well as, Moe  The variables Gender, Distance, LHS, CRLVDWL and TRCOST have consistent signs but are not statistically significant. In addition, the result has shown that Age has the negative effect on the forest dependency but is not statistically significant. As, the Wald test value of the Distance, CRLVDWL, and Gender are very small, these variables are not the important factor in the PBZCFUG to explain the forest dependency. The household's transaction cost (TRCOST) of the management of PBZCF is very low with respect to the total income of the forest, which has resulted the positive relationship but nonsignificant in comparison to other variables. Bhandari and Uibrig (2008) found that the transaction cost of management of Kalika BZCF of CNP was US$ 51.9 which was about three times less than the household transaction cost of the Choutari CF (not Protected Area CF) and this shows that the buffer zone community forest holds less forest management activities and has less effect on forest resources collection with respect to the transaction cost.

Conclusion
Buffer-zone management of the Protected Areas has fostered social capital, facilitated resources use and promoted development. Hence organizational strengthening of PBZCFUG is thus appreciable. However, the household's collection/consumption of the forest products behind managing a buffer zone community forest seems to be unmanaged and not sustainable in case of PBZCF. Thus understanding the dependency of households on the buffer zone community forest of CNP is critical for developing management strategies of CNP and the management plan (operational plan) of PBZCF. Firewood and fodder are the main forest products collected by the households of PBZCF. This study found that poor households in the Naya Belhani village with low average income are highly dependent on the PBZCF. Annually these poor households collect a large quantity of fuel wood and fodder from the PBZCF and the forest income shares 35% of their total income. Furthermore, results of logistic regression analysis revealed that agriculture income and education is shown to reduce forest dependency; and wealth status: poor, livestock population and household size of the family members increases the forest dependency of the households of PBZCFUG.
In this context, the positive and the negative significant relationships should be respectively minimized and maximized in order to enhance greater cooperation from user members of PBZCF and achieve sustainable conservation of CNP and its PBZCF with the proper utilization of forest products. Hence, policy interventions to ensure long-term success of landscape-level conservation are needed to decrease dependence on natural resources. In this situation, decentralization program such as BZCF need to be more carefully designed so that participation can be biased in favor of the poor and the marginal. All of these findings point to one thing. Rural poverty will exacerbate the need for forest resources and thus increase the household dependency on the PBZCF of CNP. Although the report of Ministry of Forests and Soil Conservation of Nepal states the Master Plan for Forestry Sector has ''enhanced the livelihoods of the rural people who have been involved while giving special focus to the needs of poor and disadvantaged households,'' it also cautions that the policy has ''failed to have significant impacts on rural employment and the local economy,'' noting that ''a clear policy for the allocation of national forest to the various community-based forest management regimes is lackingespecially for the Tarai region" which is the area of our study (GoN 2014 p.2).
Therefore, policy measures that aim at increasing agriculture income; generating off-farm employment opportunities such as tourism for PBZCFUG members; and maximizing environmental and conservation education through awareness program are needed to reduce forest dependency and enhance forest conservation. In addition, programs that reduce the poverty level of the poor with the livelihood upliftment of local households are needed in the management plan of PBZCF that mainly emphasize on the poor households. Moreover educational and training opportunities may be fruitful with the poverty reduction program. Furthermore, dependency over forests for supply of fodder for the livestock can be overcome through the interventions of intensives in the policy that focus on agrisilvicultural system: fodder tree farming in the buffer zone area, practicing stall-feeding and herding less number of livestock. As well as controlling family size through the provision of advantageous policy incentives and providing the funds for bio-gas plant establishment could help reduce the PBZCFUG household dependency on forest resources, which will finally support conservation of the CNP minimizing fuel wood extraction. Here attention should be given to the family's having large numbers adults who are unemployed and are in need of alternative means for income generation. As the Narayani river, with its unique landscape provides this place home for onehorned rhinoceros, tourism should be promoted in order to engage the adult members of the household in the employment generation activities. Furthermore, the management plan of PBZCF provides 5 years of forest management activities such as cleaning, pruning and thinning. If this management plan is properly implemented in the field, this may also help to reduce the pressure on fuel wood collection and the forest will be also sustainably managed according to the management plan. As a whole, the policy interventions for the sustainable balance between conservation, forest resource use, socioeconomic development, and expansion of the tourism in the buffer zone area can increase both legitimacy and efficiency of conservation efforts of Chitwan National Park.
