Tree improvement | Techniques & PracticesAnand Charvin
Tree improvement relies on understanding and using variation that naturally occurs in tree populations.
This presentation aims to allow the users to learn about tree improvement and the techniques and practices.
This presentation provides an overview of a field-based practical exercise that allows students in forestry, ecology and natural resources to develop their understanding of forest stand dynamics. The exercise involves measurement of key tree growth parameters in four even-aged, single-species plantation stands of different age but occupying sites with similar soil and environmental characteristics. The selected stands represent key stages in stand development, from establishment to rotation age for fibre production. In the field, students work in small teams to gather data from an equal number of plots within each stand. Tree parameters include top height, crown diameter, live crown ratio and diameter at breast height. In addition, information on stand density and understorey vegetation is collected. Plot size and number can be varied to suit the constraints of class size and available time, though circular plots of 100 m2 are recommended. In the classroom, data are pooled and analysis focuses on presenting tree and vegetation changes through time. The simplest way of interpreting the data is to prepare graphs and charts for each of the parameters, though more advanced statistical interpretations are possible. The project as outlined here can be modified to meet the needs of different groups, and has been successfully used in undergraduate teaching of silviculture and forest ecology, as well as in postgraduate courses in natural resources management.

Agroforestry has a high potential for simultaneously satisfying three important objectives viz., protecting and also stabilizing the ecosystems; producing a high level of output of economic goods; and improving the income and basic materials to the rural population. It has helped in the rehabilitation of the degraded lands on the one hand and has increased farm productivity on the other. At present, agroforestry meets almost half of the demand for fuelwood, 2/3 of the small timber, approx. 70-80 per cent wood for plywood, 60 per cent raw material for paper pulp and approx. 9-11 per cent of the green fodder requirement of livestock, besides meeting the subsistence needs of the households for food, fruit, fiber, medicine etc.
Impact Assessment of Agroforestry Practices on Community Socio-Economic Livel...Agriculture Journal IJOEAR
Agroforestry is the source of energy for cooking, materials for construction, domestic utensils and other products and services including fruits, medicine, livestock, feeding and fencing. This study aimed to assess the impact of agroforestry practices on community"s socioeconomic livelihoods in Karongi district, western Rwanda. The authors interviewed 45 Agroforestry Practioners (AFP) and 45 Non-Agroforestry Practioners (NAFP) from 8 cells randomly selected between July and September 2019.The data were analyzed by using the Statistical Package for Social Sciences (SPSS), version 20. The result, as asserted by 100 % of AFP, the Grevillea robustae was the frequently planted specie on contours and terraces due to its contribution on improving soil fertility and protecting the soil against erosion. The inheritance of land is the main mode of getting lands as mentioned by 69% and 62% of AFP and NAFP, respectively. In addition, it was noted that the number of reared goat, cattle and poultry is higher for the AFP than that of NAFP. Furthermore, the AFP" mean yearly income and its uses (food security, agriculture and household building) is significantly higher (p<0.05) compared to that of NAFP. Thus, in Karongi District, the agroforestry significantly enhances its practioner"s livelihoods. This study can serve as guide to other similar areas in adopting the agroforestry.
Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organisms’ complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress. Moreover, the review accentuates miRNAs grey areas to be addressed and gives recommendations for further studies.

Diabetes is a rapidly and serious health problem in Pakistan. This chronic condition is associated with serious long-term complications, including higher risk of heart disease and stroke. Aggressive treatment of hypertension and hyperlipideamia can result in a substantial reduction in cardiovascular events in patients with diabetes 1. Consequently pharmacist-led diabetes cardiovascular risk (DCVR) clinics have been established in both primary and secondary care sites in NHS Lothian during the past five years. An audit of the pharmaceutical care delivery at the clinics was conducted in order to evaluate practice and to standardize the pharmacists’ documentation of outcomes. Pharmaceutical care issues (PCI) and patient details were collected both prospectively and retrospectively from three DCVR clinics. The PCI`s were categorized according to a triangularised system consisting of multiple categories. These were ‘checks’, ‘changes’ (‘change in drug therapy process’ and ‘change in drug therapy’), ‘drug therapy problems’ and ‘quality assurance descriptors’ (‘timer perspective’ and ‘degree of change’). A verified medication assessment tool (MAT) for patients with chronic cardiovascular disease was applied to the patients from one of the clinics. The tool was used to quantify PCI`s and pharmacist actions that were centered on implementing or enforcing clinical guideline standards. A database was developed to be used as an assessment tool and to standardize the documentation of achievement of outcomes. Feedback on the audit of the pharmaceutical care delivery and the database was received from the DCVR clinic pharmacist at a focus group meeting.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

Challenge and Opportunities of Agroforestry practices in
Nepal for fuel wood supply and environmental improvement
Presenter
Divesh Shrestha
Roll no : 6
M.Sc. Forestry
2. Introduction
• There are seven agroforestry systems in Nepal. They are : agrisilviculture, silvopastoral,
agrosilvipastoral, Silvofishery, home gardens, woodlots and shifting cultivation
(Amatya, et al, 2018).
• Agroforestry could be defined as a practice of raising
trees and agricultural crops in a given space and time
(Amatya, 2016).
• An agroforestry practice is defined by the combination of
agroforestry components particularly species having
unique biological and economics relationships requiring
similar management strategies and techniques. An
example of agroforestry practice is Utis– Cardamom
agroforestry (Alnus- Amomum sabulatum) in Eastern and
Central Nepal (Amatya, et al, 2018).
3. Introduction cont.…
• Based on a survey of agroforestry systems and practices in
Nepal, 35 agroforestry practices within seven agroforestry
systems are documented (Amatya, et al, 2018).
• Traditionally, the people of Nepal are heavily dependent
on forests for the supply of fuelwood, fodder, and timber.
Fuel wood alone contributes about 85% of the total
energy. Different types of agroforestry systems support
the requirement of fuelwood (Paudel et al., 2017).
• Agroforestry has been claimed, to have the possibility of
improving agricultural land use systems and providing
lasting benefits and alleviating adverse environmental
effects at local and global levels (Paudel et al., 2017).
4. Objectives
• To explore the challenge and opportunities of agroforestry practices in
Nepal for fuel wood supply and environmental improvement.
5. Methodology
• Secondary data
• Different literatures, journals & thesis reports.
• Other related materials from different sources.
6. Finding and Discussion
• Fuel wood alone contributes about 85% of the total energy and rests come from other
source of energy (MoFSC, 2011). According to the Annual Household survey 2015/2016
60.9% of the people in Nepal use firewood still a major source of cooking fuel. Annual
household demand/consumption of fuel wood for Nepal is urban 1438 kg and rural
2958 kg.
• Opportunities
• A lot of fuel is generated from agricultural residues
such as straw and dried stalks as well as cowdung,
farmers cultivate Dalbergia sissoo and Cajanus cajan
which twigs and woody stalks are used to enhance
the calorific value of the cow dung sticks "Guintha“
(Paudel et al., 2017).
7. Finding and Discussion
• The two major environmental benefits are carbon sequestration and biodiversity
conservation. Soil C stocks have been demonstrated to generally be larger in
agroforestry systems compared to conventional cropping systems (Kumar and
Nair, 2011).
• In Nepal, Pandit et al., (2012) estimated that a total of 48.60 ton C per hectare
per year carbon stock from agriculture practice whereas Bajracharya et al.,
(2015) found that leasehold agroforestry in cool agroecological has more carbon
stock than conventional agriculture practice.
• Agroforestry promotes farm trees that can sequester carbon and thus
contributes in mitigating climate change, building resilience to climate variability
and increasing food security and income at the household and national level
(Bhatterai, Joshi, Windhorst, & Ning, 2016).
8. Finding and Discussion Cont.…
• Agroforestry policy 2076 provides the opportunities to develop agroforestry
models with appropriate species of plants.
• 6.1.5 Facilitation will be done in the transportation and selling of produced Forest
based products from Agro-forestry practice.
• 6.7.3 Needed support and services will be provided to employees and technicians
willing to receive higher education in Agro-forestry subject.
• 6.5.2 In specified areas, Agro-forestry models will be tested and referred.
• Tree on farm site protect soil from degradation
due to rain, wind and radiation while protecting
the flora and fauna from overexploitation. Trees
also help muffle urban noise (Paudel et al.,
2017).
9. Finding and Discussion Contd…
• Challenges
• FAO, 2015 explained challenges which are delayed return on investment,
under-developed markets, emphasis on commercial agriculture, limited
awareness of the advantages of agroforestry, unclear status of land and tree
resources, adverse regulations and lack of coordination between sectors.
• Due to hilly topography, the majority of agricultural fields, particularly irrigated
rice fields, are terraced. Farmers do not grow trees in irrigated paddy fields.
They do, however, grow trees on rain fed terraces or on degraded lands
(Amatya, 1999).
• In public land agro forestry in Nepal, conflicts with the local elites,
legitimization, choice of management models and equitable benefit sharing,
tenure security, unpaid ecosystem services and forest regeneration versus
livelihoods are the major issues.
10. Finding and Discussion Contd…
• Some studies reveal that some of the AF practice system raises the
Greenhouse gases emission by 30% yearly like shifting cultivation,
pasture maintenance by burning and over fertilization (IPCC, 2007).
• Farmers have limited access to improved tree seeds, new technologies,
and market opportunities (DoF, 2015). The time it takes to obtain the
permit for harvesting and transport from three government agencies:
Municipalities/Rural Municipalities, the Department of Land Revenue,
and the Department of Cadastral Survey (Amatya & Lamsal, 2017).
• There is also a lack of financial incentive, including access to credit
from financial institutions for owners to grow trees on their farm land.
Such constraint disincentives farmers and jeopardises the ability of
farmers (Amatya & Lamsal, 2017).
11. Conclusion
• In Nepal, 35 agroforestry practices within seven agroforestry systems are
documented.
• Majority of the Nepalese depends upon the fuelwood for the household
purposes. Agroforestry play an important role in the fuelwood supply reducing
the pressure from the forest.
• Tree-based farmland tree play significant role to carbon sequestration both in
above and below ground as well as reduces biodiversity conservation from
agricultural practices.
12. Way Forward
• The government of Nepal should focus on increasing growing of AF
species in private land and provide financial incentives.
• Farmers should encourage to grow trees in irrigated paddy fields in
hilly topography.
• There should be provision of financial incentive, including access to
credit from financial institutions for owners
