Quantitative and financial evaluation of non-timber forest products(case study:Zemkan basin forests,West of Iran)

Although Zagros forests in western Iran lack industrial timber value due to the severe climate and socioeconomics problems, non-timber products are of great value and importance due to their high economic potential and also their potential to improve the welfare of forestdwelling and forest-fringe villagers. This study was done in the forests of the Zemkan basin, an important part of central Zagros forests, Iran, to recognize the non-timber forest products（NTFPS）, investigate their potential economic value and role in people＇s livelihood. Data, collected using forest cruising, participatory observations, interviews with indigenous and local persons and experts, identified wild pistachio resin, wild pistachio fruit, oak fruit and oak syrup（Shokeh manna） among the non-timber products in this basin with total potential harvestable NTFPs of 77.16,771.602, 13248.68, and 1324.868 tons per year,respectively. The economic rent from NTFPs is 33 US$/ha/year and its total expected values with consideration of real interest rate when the exploiter invests the capital in the bank（6.4 %） and when money is borrowed from the bank to execute the incorporated projects（8.4 %） are $516/ha and $393/ha, respectively. Furthermore, families＇ economic share from potential profit of NTFPs is annually$601 per household. In addition wild pistachio resin has the highest share of the total potential profit of NTFPs and its equal to 51 % of the total of potential profit of NTFPs.Therefore, it is suggested that decisions be made to increase the infrastructure and strengthen the local selling market to enhance the cash income from NTFPs. Forest participatory management practices are suggested to organize and improve traditional use of the forests.

Grouping tree species to estimate basal area increment in temperate multispecies forests in Durango,Mexico

Multispecies forests have received increased scientific attention,driven by the hypothesis that biodiversity improves ecological resilience.However,a greater species diversity presents challenges for forest management and research.Our study aims to develop basal area growth models for tree species cohorts.The analysis is based on a dataset of 423 permanent plots(2,500 m^(2))located in temperate forests in Durango,Mexico.First,we define tree species cohorts based on individual and neighborhood-based variables using a combination of principal component and cluster analyses.Then,we estimate the basal area increment of each cohort through the generalized additive model to describe the effect of tree size,competition,stand density and site quality.The principal component and cluster analyses assign a total of 37 tree species to eight cohorts that differed primarily with regard to the distribution of tree size and vertical position within the community.The generalized additive models provide satisfactory estimates of tree growth for the species cohorts,explaining between 19 and 53 percent of the total variation of basal area increment,and highlight the following results:i)most cohorts show a"rise-and-fall"effect of tree size on tree growth;ii)surprisingly,the competition index"basal area of larger trees"had showed a positive effect in four of the eight cohorts;iii)stand density had a negative effect on basal area increment,though the effect was minor in medium-and high-density stands,and iv)basal area growth was positively correlated with site quality except for an oak cohort.The developed species cohorts and growth models provide insight into their particular ecological features and growth patterns that may support the development of sustainable management strategies for temperate multispecies forests.

Effects of bioenergy production on environmental sustainability:a preliminary study based on expert opinions in Italy and Turkey

In future decades, initiatives on biomass-based energy development in Europe should reduce fossil fuel dependence and help to combat climate change as required by the conference of the parties 21. In this context, forest biomass can play a key role within the bioenergy sector due to its high growth potential. The use of forest biomass for energy has positive and negative effects on other ecosystem services, on stand characteristics, and on forest management practices. The aim of this study is to analyse the effects of forest bioenergy production on six ecosystem services(biodiversity, recreation, landscape aesthetics,carbon sequestration, soil erosion protection, water quality). These effects have been assessed by 80 experts in two countries(Italy and Turkey), considering two different forest management practices(clear-cutting of coppices and woody residue removal after felling in high forests). The results show that coppice clear-cutting has negative effects on almost all ecosystem services according to the experts’ opinions. The highest negative effects are on landscape aesthetics and soil protection. The effects of woody residue removal on biodiversity, carbon sequestration, soil erosion protection, and water quality are considered negative by the experts, while the effects on recreation activities and landscape aesthetics are considered positive. The highest negative effects of this forest management scenario are on soil protection and biodiversity. The experts’ opinions about the effects of forest management practices on ecosystem services can provide information to understand the environmental sustainability of bioenergy development in future years.

Analysis of Staffing and Training Needs for Effective Delivery of Extension Service in Sustainable Land Management in Kilimanjaro Region, Tanzania

An assessment of staffing and training needs for effective delivery of extension services in mainstreaming sustainable land management (SLM) practices in Kilimanjaro Region was conducted in June/July 2013. Data collection methods included discussions with key informants at the regional and district levels, consultations with village level stakeholders and potential collaborators, review of human resources data both at regional, district and ward levels and collection of individual staff bio-data including capacity deficiencies. The staffing situation at the regional and district levels was considered to be adequate for effective mainstreaming of SLM interventions in the region. Staffing at ward and village levels was very poor and largely inadequate for sustainable execution of extension services. It is optimistically estimated that on average the staffing at ward level needs to be increased by at least 50%. In some districts the deficiency of extension staff at ward level was as high as 80%. Training needs exist at all levels from the region down to community level. At the regional and district levels both long and short term training programs were required. At the community level required training is more practical and purely focused in mainstreaming SLM interventions at individual households and community lands. Potential collaborators with local government were identified in four main categories namely, NGOs/CBOs, private sector, government departments and faith-based organizations. The study recommends a capacity building program on specific knowledge gaps identified at regional, district, ward and village levels. The study further recommends that immediate measures need to be taken by the district authorities to address the staffing problem at ward level including recruitment of volunteers and developing collaboration framework with identified potential partners.

Analytical Framework Model for Capacity Needs Assessment and Strategic Capacity Development within the Local Government Structure in Tanzania

This is a methodological paper prepared by senior academicians, researchers and consultants from renowned universities in Tanzania. The paper provides insights as to how best development agents can approach the challenge of capacity needs assessment and development of capacity building programs in the context of the local government structure in Tanzania. The paper is of original nature and is based on author’s accumulated knowledge and practice in conducting capacity assessments and developing capacity building programs in Tanzania. The paper describes what can be considered to be best practices in conducting participatory capacity assessment through consultative processes which involves most of the key actors who would be engaged in implementing proposed interventions. The paper puts forward an analytical model for capacity assessment and program development in the Tanzanian context. The main features of the model can be summarized as participatory capacity assessment, strategic capacity building program development and complementarity through synergy building with like-minded stakeholders. The operational modality for utilizing the model in developing capacity building programs which among other components has monitoring and evaluation aspects is included. It is recommended that practitioners and development agents should test the model in their working environments to realize its potential benefits including program ownership by stakeholders.

Illegal logging in ASEAN:status,cause,impacts and management process

Illegal logging has become a serious problem in forest management in ASEAN. In the paper, the illegal logging status in ASEAN is introduced, and it is sure that Indonesia, Malaysia, Brunei, Laos, Myanmar and Cambodia are production countries, Thailand and Vietnam are the processing countries, and Philippines, Singapore are consumer countries in the whole supply chain of illegal logging. As well, the trade flows of illegal forest products of ASEAN are checked, the cause of illegal logging and its producing impacts are assessed. To tackle illegal logging, one feasible way is to design ecological supply chain to supervise illegal logging process, and under the concept of ecological supply chain, the production countries, processing countries and consumer countries should take actions together. Non-ASEAN countries should improve border control, introduce public procurement policies, promote market-based instruments, and strengthen international cooperation. For ASEAN countries, they should establish cooperation mechanisms within the region, take a unified action, increase governance capacity and promote legality verification or sustainability certification.
