Expansion of Planted Forests: The Risk of Pesticides Mixtures

Planted forests include forests established through human planting or deliberate seeding. They are systems that offer us timber and non-timber forest products and ecosystem services, such as wildlife protection, carbon sequestration, soil, and watershed maintenance. Brazil has 7.6 million hectares of planted forests, with 72% of the total area occupied by Eucalyptus spp. A favorable climate and management and genetic improvement research are the main factors responsible for high productivity. In recent years, the expansion of planted areas has been accompanied by the commercial release of several pesticides, mainly herbicides. A recent change in the Brazilian legislation allows mixing phytosanitary products in a spray tank, having a new approach to managing pests, diseases, and weeds. Antagonism is the main risk of tank mixes, and to reduce the dangers associated with this practice, we review all products registered for growing Eucalyptus. This literature review aims to identify the effects of product mixtures registered for Eucalyptus reported for other crops. In addition, environmental and social risk assessment has been widely adopted to export wood and cellulose, making the results of this review an indispensable tool in identifying the nature and degree of risks associated with pesticides. The results classify the effects of the mixtures as an additive, antagonistic or synergistic. The use of pesticide tank mixtures has the potential for expansion. However, there are still challenges regarding variations in the effects and applications in different climatic conditions. Therefore, studies that prove efficient mixtures for the forest sector are essential and the training of human resources.

Morphological variation of Aceh Pinus (Pinus merkusii)

The genus Pinus is classified as one of the most widely distributed genera of conifer trees, that are majorly distributed in the Northern and Southern hemispheres. Pinus merkusii is the only member of the genus Pinus that is adapted in the tropics and grows naturally in south Equator. Its natural distribution found through-out Southeast Asia, e.g. in Indonesia; particularly on Sumatran Island. Three native strains are known on Sumatra: Aceh, Kerinci, and Tapanuli; with the first one is known as the largest population among the three and grows naturally on the high altitudes. The wood has been utilized in building construction, while the resin collected is classified as one of the most valuable Non Timber Forest Products (NTFP) worth up to US $ 50 million/year and applied in many industries. Planting of citron grass (Cymbopogon sp.) has been ’booming’ over the past seven years in the middle regions of Aceh due to its attractive selling price. As consequences, many Pinus trees have been logged and demanded as fire woods in the distillation process of citron grass. Thus, the citron grass’ plantation has been directly threatening the existence of Pinus forests. Therefore, in-situ conservation effort should be started from now on. Here, we would like to report the morphological variation (N= 15 traits) of natural Pinus (e.g., plant height, diameter of main stem, number of crowns per branch, etc.). The morphological data collected were then analysed with the Principal Component Analyses (PCA), in order to cluster the major agronomical parameters among them. This morphological data would be complemented and benefitted the efforts in the genetic study of Aceh Pinus.

PENGELOLAAN HUTAN DESA DI KPH WILAYAH VIII SEMENDO DARI PERSPEKTIF KINERJA KELEMBAGAAN

Muara Danau Village Forest Management Institution (LPHD) is a forum on forest management activities that aim to improve community welfare. At present, the condition of the farming business is not effective, so it requires some rules as a measure of success. This study aims to analyze the institution of the Muara Danau Village Forest Management Institution (LPHD) in the implementation of Village Forest Management. The research was conducted in Muara Danau Village, Semende Darat Laut Subdistrict, Muara Enim Regency, South Sumatra Province, from March to April 2020. Data were analyzed by using the SSBP approach. The results of the study showed the situation of farmers utilizing forest resources in the form of water sources and non-timber forest products. Smallholders manage the forest based on institutional structure stated in the AD/ART, and administrative sanctions. In terms of planting patterns in the arable land, the structure controls farmer behavior by using an agroforestry system. This makes Muara Danau Village Forest Management Institution (LPHD) obtain a good performance in the aspect of institutional management which is measured by the involvement of members and institutional administrators in group activities/training (91%) and the types of binding group rules in the form of written rules (AD/ART) as well as unwritten rules (84%) in managing areas measured based on the type of forest resource conservation activity (95%). However, managing businesses have not obtained optimal results, as measured by the absence of institutions that handle the marketing of forest products for groups (cooperatives). Based on the results of the research, the institution of Muara Danau Village Forest Management Institution (LPHD) is categorized as good.

Contributions of some non-timber forest products to household income of rural dwellers in Onigambari Forest Reserve, Oyo State, Nigeria

The communities surrounding the forest reserve get their daily income from the sales of some of the non-timber forest products (NTFPs) as a means of survival for them and their house hold without proper documentation. The study described the socio-economic characteristics of the rural dwellers in the study area and determined the income made from some of these NTFPs. Data was generated through the use of structured questionnaires administered to 120 randomly selected rural household heads. Data obtained were described using frequency counts, percentages and mean scores; the relationship between dependent variables and independent variables of the study was tested using binomial test and logistic regression. Finding reveal that, non-timber forest products gathering in Onigambari was male dominated (72.3%), 78.1% were married and 38.1% had formal education. Contribution of income from non-timberforest products to total income of respondents in the State was 59.46%. It was concluded that the non-timber forest products contribute significantly to rural household income at Onigambari forest Reserve Area of Oyo State, Nigeria

Stadiochilus R. M. Sm. (Zingiberaceae: Zingibereae), a new generic record for India

The monotypic ginger genus Stadiochilus R. M. Sm. with S. burmanicus R. M. Sm. earlier known from Myanmar is reported here as a new record for India from the state of Nagaland. A detailed taxonomic description along with photographic illustrations of S. burmanicus is given. For conservation purposes, the IUCN status of this species has been evaluated as Endangered. The present field study ascertained that extraction of timber and non-timber forest products, forest fires and shifting cultivation are the major threats to the species in the locality in Nagaland reported here.

Current Challenges and Prospects of Indonesian Non-Timber Forest Products (NTFPs): A Review

Non-Timber Forest Products (NTFPs) management can lead to various benefits for community livelihood and forest sustainability. However, such management has not been carried out optimally and sustainably in Indonesia, due to various limiting factors including ineffective policies, undeveloped cultivation technologies, and inadequate innovation in processing technologies. Further, the diversity of NTFPs species requires that policy-makers determine the priority species to be developed. Agarwood (Aquilaria spp. and Gyrinops spp.), benzoin (Styrax spp.), sandalwood (Santalum album L.), and cajuput (Melaleuca cajuputi Powell) are aromatic NTFPs species in Indonesia that forest-dwellers have utilized across generations. This paper reviews the current governance, cultivation systems, processing and valuation, and benefits and uses of these species. We also highlights the future challenges and prospects of these NTFPs species, which are expected to be useful in designing NTFPs governance, in order to maximize the associated benefits for the farmers and all related stakeholders.
