Fuelwood assessment at the micro-watershed level:a case study in Garhwal Himalaya,India

Biomass,as fuelwood,is one of the major sources of energy in rural areas,especially in the mountainous regions of the world.As the increasing human population exerts more pressure on the forest thereby inducing an adverse effect on the sustainability of the ecosystem,which consequently causes fuelwood crisis at a local level,this crisis is spatio-temporal in nature.Thus,the major objective of this study is to assess the sustainability of fuelwood at different probable scenarios at a micro watershed level.The present study was conducted in the Phakot watershed,the Tehri Garhwal district of central Himalaya in India,during 2006-2008.Based on the vegetation composition in the study area,the net primary productivity(NPP)value of the Oak forest,and mixed oak and sal forests,was used for the quantification of fuelwood availability in evergreen and deciduous forests,respectively.The fuelwood demand was calculated on the basis of seasonal fuelwood consumption values.Nine probable permutations for availability-demand scenarios assuming the existence of high(H),low(L)and average(A)conditions were analyzed for evaluating the stress.The available annual harvestable fuelwood in the watershed is in the minimum and maximum ranges of 2283.28 to 4066.00 tons,respectively,per year whereas it has a demand of 110.76 tons as the minimum to 3659 tons as the maximum annually.This shows that in the current availabilitydemand scenario,the watershed does not have fuelwood crisis in the present situation but needs to maintain the sustainability of the system.Based on our study,it is concluded that,globally,more spatio-temporal study is required to understand the issues at the local level.     

Fuelwood consumption in two tribal villages of the Nanda Devi Biosphere Reserve of the Indian Himalaya and strategies for fuelwood sustainability

Fuelwood is the only important source of energy in the mountainous region of the Garhwal Himalaya, India. Since the commercial source of energy is generally beyond the reach of ordinary people due to their poor socio-economic conditions and due to limited supply and lack of communication facilities for transport of LPG, the villages of the inner region of the Garhwal Himalaya depend on their fuel requirement from the forest. In the present study, two villages of the Nanda Devi Biosphere Reserve in Uttarakhand part of the Indian Himalaya i.e. Lata and Dunagiri located at 2,415 and 3,600 m altitudes, respectively, were selected for the study of socio-economic profile and vegetation and for estimation of per capita fuelwood consumption and the degree of disturbance. The study was conducted from 2002–2005. The population of these villages is migratory and belongs to the Bhotiya community, a scheduled tribe consisting of two subgroups known as Tolcha and Marchha. They grow traditional crops as well as cash crops. Important tree species used for fuelwood include Cedrus deodara, Pinus wallichiana, Cupressus torulosa, Taxus wallichiana, Acer indicum, Quercus dilatata and Viburnum cotinifolium. Maximum density among trees was shown by Pinus wallichiana (169.6 trees ha⁻¹) in village Lata and by Cedrus deodara (89.6 trees ha⁻¹) in village Dunagiri. The average per capita consumption of fuelwood in villages Lata and Dunagiri was 4.03 and 4.77 kg capita⁻¹ day⁻¹. Maximum number of trees (29 and 31% lopping for Lata and Dunagiri, respectively) belonged to disturbance class 1 (1–20% lopping) followed by the disturbance class 2 (20–40% lopping). Due to location of these villages in the buffer zone of the biosphere reserve, the fuelwood consumption may cause an adverse impact on the ecological status of this reserve, which urgently requires employing strategies for the conservation and management of this biosphere in terms of fuelwood sustainability e.g. regulation of livestock stock and grazing, using alternative sources of fuels, plantation of multipurpose trees and adoption of ecotourism.     

Photochemical smog effects in mixed conifer forests along a natural gradient of ozone and nitrogen deposition in the San Bernardino Mountains

Toxic effects of photochemical smog on ponderosa and Jeffrey pines in the San Bernardino Mountains were discovered in the 1950s. It was revealed that ozone is the main cause of foliar injury manifested as chlorotic mottle and premature needle senescence. Various morphological, physiological and biochemical alterations in the affected plants have been reported over a period of about 40 years of multidisciplinary research. Recently, the focus of research has shifted from studying the effects of ozone to multiple pollutant effects. Recent studies have indicated that the combination of ozone and nitrogen may alter biomass allocation in pines towards that of deciduous trees, accelerate litter accumulation, and increase carbon sequestration rates in heavily polluted forests. Further study of the effects of multiple pollutants, and their long-term consequences on the mixed conifer ecosystem, cannot be adequately done using the original San Bernardino Mountains Air Pollution Gradient network. To correct deficiencies in the design, the new site network is being configured for long-term studies on multiple air pollutant concentrations and deposition, physiological and biochemical changes in trees, growth and composition of over-story species, biogeochemical cycling including carbon cycling and sequestration, water quality, and biodiversity of forest ecosystems. Eleven sites have been re-established. A comparison of 1974 stand composition with data from 2000 stand composition indicate that significant changes in species composition have occurred at some sites with less change at other sites. Moist, high-pollution sites have experienced the greatest amount of forest change, while dryer low-pollution sites have experienced the least amount of stand change. In general, ponderosa pine had the lowest basal area increases and the highest mortality across the San Bernardino Mountains.     

Biodiversity of plants and soils in landscapes adjacent to the Buzuluk Pine Forest

The influence of the Buzuluk Pine Forest on biodiversity of plants and soil properties in adjacent territories has been studied. The results show that in the immediate vicinity of the pine forest, under the influence of the relatively mild and humid mesoclimate, natural phytocenoses are dominated by mesophytic species. Biodiversity reaches a peak at a distance of 17–18 km from the forest, which is explained by the presence of both mesophytes and xerophytes in the same phytocenosis. The same zone is also characterized by the maximum diversity of soil properties and structural complexity of the soil cover. Grass communities on ordinary chernozems with a homogeneous soil cover, typical of the steppe zone, are formed at greater distances from the forest.     

Fuelwood assessment at micro-watershed level in Northeast Himalaya:a case study in Manipur,India

Fuelwood is one of the major sources of energy in the domestic sector across the rural areas,especially in the developing regions across the world.The Northeastern Himalayan state of Manipur is dominated by the tribal population that largely depends on fuelwood from the nearby forest area.The entire dependence on forests for energy resources is affecting the sustainability of the forest ecosystem in the region,thus indicating the livelihood conditions.Since land-use land-cover change is the key driver to the change in resource availability of a region,the present study has tried to analyze the landcover changes over a period 28 years.The second major component affecting resource availability is the increasing population pressure that leads to changes in the land dynamics,which directly affect the resource production.Based on the existing consumption pattern,the total consumption of fuelwood in the watershed ranges fiom a minimum of 289.992 tons/year to a maximum of 3545.719 tons/year with an average of 1561.956 tons/year in the year 2009 and simulated fuelwood consumption for the year 2021 is around 1469.260 tons/year.Nine different probable scenarios of resource are proposed to calculate the stress value that can be used by the policy-makers and planners for suitable policy implementation at the micro level with a complex social system.

Sustainable forest management in Iran: a factor analysis

Since 1996, several Forest Resources Management Plans (FRMPs) have been launched by the Iranian government in order to approach sustainable forest management in the Zagros area in west and south-west Iran. This survey study aimed to provide some policy recommendations in order to launch more successful FRMPs. Using a proportional cluster random sampling method, data were collected from 208 forest-dwellers (beneficiaries) and 90 practitioners. The results showed that the FRMPs are far from satisfactory. There are several reasons for this failure. First, the financial resources allocated to these plans are being used for other purposes. Second, the inputs and supplies needed for effective forest management interventions were not in place in a timely manner. Third, the forest management in the area is far from being decentralized. Both the beneficiaries and practitioners believe that forest-dwellers play a weak role in forest management interventions. Factor analysis revealed that three main factors influencing the Zagros management effectiveness are “the management capabilities of forest-dwellers”, “the professional capabilities of practitioners in forest management”, and “public support for forest-dwellers”. The correlation analysis revealed that all the three factors are also positively and significantly associated with the success of the government’s forestry programs. Accordingly, the main recommendation of this study was to reformulate forest management policies in the Zagros area by highlighting participatory approaches, not only as a tool, but also as a goal of FRMPs.     

Who is importing forest products from Africa to China? An analysis of implications for initiatives to enhance legality and sustainability

Global forest product value chains are increasingly subject to regulatory requirements, such as legality and sustainability certification. For African forest products, a shift in the export destinations of forest products towards China, the leading timber product manufacturer, has raised concerns that social and environmental product and process standards are declining. Aggregate drivers of this shift have been documented, yet there has been little enterprise-level analysis of Chinese actors in African timber imports based in China. This paper provides an initial analysis, highlighting implications for existing and emerging regulatory initiatives. Data show that although an increasing number of Chinese private enterprises is engaged in African timber imports, import volumes remain concentrated among a small number of geographically clustered private and state-owned firms. Government-led schemes are beginning to address timber legality concerns. But given China’s growing domestic market for finished wood products, sustainability certification requirements driven by the US and EU will not be sufficient to ensure improved sourcing by Chinese firms.     

怒江流域森林资源的本土利用调查与分析

基于怒江流域北段高黎贡山自然保护区周边4个社区的森林资源利用状况详细调查数据,运用建房频率计算农村地区建房周期、气干密度换算薪材材积等方法,分别依本土居民的建材、薪材、围栏（篱）用材和非木材林产品（NWFPs）4种森林资源利用方式,计算、分析怒江流域北段森林资源当地利用的消耗量和消耗结构。结果显示：怒江流域北段建房材消耗量0.10 m³ /a·人,薪材3.87 m³/a·人,农地围栏用材0.019 m³/a·人,年户均采集以菌类和中药材为主的非木材林产品73.95 kg。表明消耗量最大的利用形式是薪材,而非传统认为的建房材和农地围栏材;农村社区木楞房、木片房和农地围栏“长期留存”,而薪材流量大“库存小”的表象,是导致认识偏差的原因。调查社区的地理位置、社区规模和民族组成等在怒江流域北段具较强代表性,结果可为调查区森林资源可持续经营提供参考,也可为高黎贡山（怒江）国家级自然保护区的科学管理提供依据.     

Climate change impacts on a pine stand in Central Siberia

The objective of this paper is to analyse the impacts of climate change on a pine forest stand in Central Siberia (Zotino) to assess benefits and risks for such forests in the future. We use the regional statistical climate model STARS to develop a set of climate change scenarios assuming a temperature increase by mid-century of 1, 2, 3 and 4 K. The process-based forest growth model 4C is applied to a 200-year-old pine forest to analyse impacts on carbon and water balance as well as the risk of fire under these climate change scenarios. The climate scenarios indicate precipitation increases mainly during winter and decreases during summer with increasing temperature trend. They cause rising forest productivity up to about 20 % in spite of increasing respiration losses. At the same time, the water-use efficiency increases slightly from 2.0 g C l^?1 H₂O under current climate to 2.1 g C l^?1 H₂O under 4 K scenario indicating that higher water losses from increasing evapotranspiration do not appear to lead to water limitations for the productivity at this site. The simulated actual evaporation increases by up to 32 %, but the climatic water balance decreases by up to 20 % with increasing temperature trend. In contrast, the risk of fire indicated by the Nesterov index clearly increases. Our analysis confirms increasing productivity of the boreal pine stand but also highlights increasing drought stress and risks from abiotic disturbances which could cancel out productivity gains.     

Non-timber forest products certification in India: opportunities and challenges

Forest certification has emerged as a marketing tool for linking the good forest management practices with the environmentally conscious consumers. Its genesis can be attributed to the society’s concern for the social and environmental significance of forests. Forest management certification when coupled with the chain-of-custody certification; then, the supply chain stages for such forest products can carry an ecolabel. Non-timber forest products (NTFPs) are of socio-economic and cultural importance for the forest dwelling communities, particularly for the tropical countries like India. India is home to an amazing diversity of plants, with over 46,000 plant species recorded to occur there. NTFP’s availability, utilization, commercialization, exploitation, management practices, policies and tenure systems in different parts of India have high diversity and variability. There is concern, however, that collection methods for most of NTFP species are destructive and wild populations are declining as a result. Thus, the harvest of NTFPs is coming under increasing scrutiny from certification programmes, as it plays a key role in the sustainable management of forest resources and community benefit worldwide. Thus, the present research paper highlights the issues relevant to certification of NTFPs in India, based on more than a decadal experience in dealing with this subject at Indian Institute of Forest Management, Bhopal.     

Landscape diversity and associated coping strategies during food shortage periods: evidence from the Sudano-Sahelian region of Burkina Faso

The importance of forest resources for rural communities’ livelihoods has increasingly been recognized over the last three decades. Forests provide food, generate incomes, provide supporting (nutrient cycling, pollination), and regulating (climate, diseases, water regulation and purification) services for agriculture, in addition to their aesthetic, cultural and spiritual role. However, most of the studies on forest resource use do not focus on the role of landscape organization in addressing the impact of climate variability and the risk of food insecurity. This study aims to examine the contribution of woodlands and trees towards decreasing the risk of food insecurity and the importance of landscape structure and composition in coping with food shortages. It took place in two villages in Burkina Faso, on both ends of the woodlands and tree-cover spectrum. We demonstrate that in both landscapes, ecosystem goods, such as shea nuts and fuelwood, represent a safety net for households during food shortage periods. We demonstrate that households shape their adaptive strategies differently depending on the resources available and the structure of the landscape. People living in a landscape with a savannah matrix (Sorobouly) rely on fuelwood trade to purchase cereals, while those living in a landscape with a parkland matrix (Kalembouly) rely on shea nuts. Agricultural, environmental and climate change policies that reinforce the rights of the most vulnerable to access key resources provided by these landscapes and development programs which assure their sustainable use will simultaneously enhance food security and increase their adaptive capacity in the face of climate change and variability.

     

Divergence of biogeocenoses within pine forest types

The paper is devoted to the analysis and generalization of the results of stationary studies on differentiation of factors of the epi-soil environment, natural forest regeneration, and formation of secondary dendrocenoses on burns and clean cuts in two pine forest types most prevalent in the pre-forest–steppe subzone of Western Siberia (Pripyshmiskian pine forests). It is shown that the same primary forest type (or even biogeocenosis) in burns, on the one hand, and in clean cuts, on the other hand, is replaced by two types of biogeocenoses that are alternative to each other in terms of structure and functions and represent qualitatively different, diverging ecodynamic series of natural regeneration and development of the primary, autochthonous forest type.     

The effect of natural and anthropogenic disturbance in forest canopy and its effect on species richness in forests of Uttarakhand Himalaya,India

Pinus roxburghii (chir-pine) and Quercus leucothchophora (banj-oak) are dominant forests of mountainous part of the Uttarakhand Himalaya. The continued anthropogenic disturbance is opening the canopy, forming canopy gaps and as a result forest fragments are developing. Thus, the present study aims to analyze variations in species richness and vegetational parameters in relation to canopy gaps in forests. Total species richness was greater in open canopied forest compared to moderate and close canopied forests. In comparison between oak and pine forest, it was greater in oak forest while the proportion of common species was low between oak—pine forests. Mean species richness did not significantly vary from one canopy gap to another as well as in oak and pine dominated forest. This indicated that dominant forest types played an important role to form the community structure. The shrubs richness were greater in closed canopy and between the forests it was greater in pine forest. Tree and shrub density was low in open canopy while herb density was high in moderate canopy. Thus, this study indicated that the dominant canopy species play an important role in deciding the community structures especially the distribution of under canopy species. These parameters should be considered for conservation and maintenance of plant biodiversity of a region.     

Revisit to community forest in northeast of Thailand: changes in status and utilization

The International Forest Resources and Institutions (IFRI) research program is designed by a network of social and natural scientists from different parts of the world and is intended to exam the interdependency relations between people and forests and to analyze forest conditions In 2003, in terms of IFRI methodology, our team has done some relative research in Kog Bung Preu community forest, which locates in the northeast of Thailand, and collected forest data including some key variables and parameters, such as DBH (Diameter at Breast Height), HEIGHT, BA (Basal Area), and DENSITY of trees and saplings in 31 plots in this community forest. In 2009, we re-visited the forests and 31 forest plots, using IFRI methodology and GPS technology again to collect data based on four key variables of trees and saplings. In the process of data management and analysis, we use IFRI Data Entry Application, and Access, Excel, SPSS, Map-source etc. to help us manage and analyze collected data. Meanwhile, a variety of qualitative and quantitative techniques were used to understand and analyze different variables and data. This paper will mainly focus on the changes in the Kog Bung Preu forest since last visit. By comparing and analyzing the forest plot data of two visits by using macro- and micro-scale, it is intended to reveal the actual status of Kog Bung Preu forest and to discuss the reasons behind the changes. From fieldwork and investigation in 31 forest plots and community residents again, we found that for saplings, DHB has slightly increased, however it did not test as significantly different, unlike HEIGHT which had also increased and had significant differences between the 2 years. Density and basal area for sapling revealed the same trend. They appeared to be notably decreasing from 2003 to 2009. BA does not prove to be significantly different, but DENSITY has a significant difference. Comparing tree variables between 2003 and 2009 gave different results. Every variable showed an increase from the previously recorded data. However, only the DBH and HEIGHT of trees demonstrated significant differences between the 2 years. The generally declining rate of sapling density and basal area may be related to the increase in the density and basal area of trees. It may be assumed that within the 6-year period, some saplings in the plots matured and now fall into the tree class. During this study, a total of 78 species in 38 families were recorded; 51 species are trees belonging to 22 families, 25 species from 14 families are saplings, 12 species from 9 families are seedlings, 2 woody climber species were recorded from 1 family; and herbs and grasses consisting of 27 Species from 16 families. Species composition has decreased compared to data recorded in 2003 from 97 to 78 species in 2009 as well as families which had higher recorded counts in 2003 (48 families) but lower recorded counts in 2009 (38 families). The socioeconomic situation of local community has some changes, from interview we found that most of changes focus on the collection of forest products and timber uses. The interaction between forest and people has improved. Finally, based on the analysis earlier, we discussed some aspects and provide relative suggestions.     

Poverty alleviation as a pathway to sustainable forest management

In a major deviation from conventional joint forest management approaches where the emphasis of management is on provision of forest products to the participating villagers, the Tamil Nadu Afforestation Project (TAP) focused on poverty alleviation as the principal means to achieve sustainable forest management. This study assesses the effectiveness of TAP’s strategy in improving the ecology and socio-economic conditions of forest fringe villages using a diverse set of research methods. Results indicate that in a span of four to seven years, there was significant increase in forest cover, biodiversity, and agricultural productivity. The project villages have also shown considerable progress in various indicators of socio-economic development. The authors, however, suggest continued poverty alleviation and promotion of alternative livelihood opportunities to place the programme on a stable ground. Meeting the development needs of local villagers through strong and durable institutional linkages is also suggested for the programme to sustain and succeed.     

Impacts of business-as-usual management on ecosystem services in European mountain ranges under climate change

Mountain forests provide a multitude of services beyond timber production. In a large European project (ARANGE—Advanced multifunctional forest management in European mountain RANGEs), the impacts of climate change and forest management on ecosystem services (ES) were assessed. Here, we provide background information about the concept that was underlying the ARANGE project, and its main objectives, research questions, and methodological approaches are presented. The project focused on synergies and trade-offs among four key ES that are relevant in European mountain ranges: timber production, carbon storage, biodiversity conservation, and protection from gravitational natural hazards. We introduce the concept and selection of case study areas (CSAs) that were used in the project; we describe the concept of representative stand types that were developed to provide a harmonized representation of forest stands and forest management in the CSAs; we explain and discuss the climate data and climate change scenarios that were applied across the seven CSAs; and we introduce the linker functions that were developed to relate stand- and landscape-scale forest features from model simulations to ES provisioning in mountain forests. Finally, we provide a brief overview of the Special Feature, with an attempt to synthesize emerging response patterns across the CSAs.     

Avian species distribution in different elevation zone forest (Sal, Pine Mixed And Oak) in nainital district of uttarakhand, India

The present study were made to estimate the avian fauna in terms of species richness and diversity and guild structure in forest habitats of Nainital district of Uttarakhand (350–2.450 m asl; 29° N). Field studies were conducted during January 2007 to December 2008. Total 43, 62 and 42 species were recorded from, Haldwani, Bhowali and Nainital forest habitats. Results indicate the species relationship between Bird species richness (BSR) and elevation sections (forest habitats) was not decline simultaneously along elevation; it shows hump shaped. BSR varied considerably along elevational gradient (43 to 62 species), was highest (62 species) at mid elevation (Mixed pine forest, 1.350–1.700 m asl) and decreased (20 species) at high elevation (Conifer forest, 1900–2450 m asl). It seems that mid altitude bulge is not caused by the presence of a group of mid altitude specialists but rather that there is an overlap in the distribution of low land and high elevation specialists at this altitude. A checklist of 79 avian species has also produced of Nainital district forest habitats. It is suggested that this study provide a base line structure for further study on species distribution in different forest habitats and along different elevation section in Western Himalayas (India).     

Local level community forest management an effective tool in conserving forest biodiversity

Forest vegetation of a community managed forest (Van Panchayat) located between 1570–1700 m elevation was studied along four aspects. Quercus leucotrichophora was the dominant species on three of the four aspects. Across the aspects the total tree density ranged between 150 and 490 ind/ha, sapling density between 100 and 370 ind/ha, seedling density varied from 241 to 1090 ind/ha. The shrub density ranged from 166 to 690 ind/ha and herb density from 6000–17100 ind/ha. The total basal area of tree layer varied from 9.78 to 13.5 m²/ha showing that the forest is young. Species diversity value for tree layer varied from 0.14 to 1.69. Quercus leucotrichophora were regenerating well due to effective forest management by local communities. The higher proportion of seedlings of Quercus leucotrichophora indicating that the Van Panchayat are playing important role in conservation of oak forest of Himalaya.     

Tigers,Tribes, and Bureaucrats: the voluntariness and socioeconomic consequences of village relocations from Melghat Tiger Reserve,India

Relocations of indigenous peoples from protected areas to promote wildlife conservation have typically resulted in negative socioeconomic results for those displaced. The international indigenous peoples’ movement has begun to coalesce around the use of free, prior, and informed consent (FPIC) as a legal mechanism to prevent disadvantageous relocations. In 2006, India’s parliament passed the Forest Rights Act, which requires any village relocation of tribal people be conditional upon their FPIC. I used household surveys and qualitative interviews of relocated and forest (not-yet relocated) villagers from Melghat Tiger Reserve, Maharashtra, to examine (a) the extent to which putatively voluntary relocations were conditional upon FPIC and (b) how such relocations affect socioeconomic metrics and overall quality of life for those relocated. I found that while consent to relocate was mostly free, consent was not fully informed across the villages examined. The socioeconomic results indicate that relocated villagers make a trade-off, leaving a familiar, healthier environment for better access to modern services and employment. Finally, I found that forest villagers in favor of relocation emphasized how the social and economic costs of remaining in the forest had become greater due to the relocation of neighboring villages. This field study suggests that strong implementation of FPIC and state responsiveness post-relocation are both necessary to safeguard forest-dwelling people from disadvantageous relocations.
