0874 Tripura State: The Role of Government and Panchyati Raj Institutions in ...SRI-Rice, Dept. of Global Development, CALS, Cornell University
The document discusses the role of the government and Panchayati Raj institutions in promoting the large-scale adoption of the System of Rice Intensification (SRI) in Tripura, India. It describes how the agriculture department and local governments worked together to demonstrate SRI techniques to over 73,000 farmers by 2007, leading to a 6% adoption rate. SRI yielded 50-100% more than conventional practices. The collaboration aimed to boost rice production and ensure food security in Tripura.Poverty impacts maize export bans Zambia Malawi 2021
This document discusses using crop modeling software (DSSAT) to simulate maize yield patterns in Zambia during an El Niño event in 2015-2016 that caused delayed rainfall. The study found that modeling supply shocks from climate events can help estimate their impacts on household incomes and food security to better guide policy responses. Policymakers often focus on ensuring food availability through trade barriers or stockpiling, but availability alone does not address the access problems and income shocks that small farmers face from poor harvests.

This study estimates the impact of drought tolerant (DT) maize varieties on food security in southern Africa. DT maize varieties are a promising technology that can help smallholder farmers adapt to drought risks. Even though DT maize varieties have shown better yield potential under experimental conditions, their impact on smallholder farms across the region has not been evaluated. We use new household data (collected in 2015) from surveys of 2,995 farm households in five countries (Angola, Mozambique, Malawi, Zambia, and Zimbabwe) to measure the impact of DT maize varieties on food security. We use households past five-year experience of drought as an instrumental variable that triggers the decision to adopt DT maize varieties and an endogenous switching regression to correct for the endogeneity of the DT adoption in estimating maize production. We also evaluate whether a household tends to be more food secure after growing a DT maize variety. Our results show that households that grew DT maize varieties had 600 kg/ha more maize than households that did not grow the DT maize varieties. Given a household of four people, with human maize consumption averaging 91 kg per capita per year, this additional maize provides an extra 1.6 months of food. Given the region's vulnerability to climate change, DT maize varieties prove to be an important adaptation option. We, therefore, recommend that governments in southern Africa promote DT maize varieties to reduce household vulnerability to climatic risks and improve food security.

This study evaluated the effects of conservation agriculture and conventional tillage practices on aggregate stability and soil organic carbon distribution in different aggregate fractions. Specifically, it compared zero tillage with and without crop residue retention to conventional tillage with and without residue retention over multiple cropping cycles of maize and wheat. The study found that zero tillage systems with residue retention led to greater total soil organic carbon levels, especially in small and large macroaggregates, compared to conventional tillage systems. Maintaining crop residues on the soil surface under no-till was the most effective practice for maximizing carbon retention in the soil.

Bio gas is produced through digestion of cattle dung in bio gas plants, also known as gobar gas plants, located in rural villages. The objectives are to provide fuel for cooking, organic manure for households, reduce pressure on forests, and improve sanitation. The construction process involves digging a pit and building a water-tight cement cylinder with intake and outflow pipes. Cattle dung and other waste is mixed into slurry and breaks down to produce methane gas, which is then stored and piped to homes for use in cooking and lighting. Subsidies are available from central and state governments to promote construction of gobar gas plants.

Drivers of landcover and landuse change in Kenya 1983 t0 2013
This document discusses changes in agriculture and land use in Kenya between 1983 and 2013. Some key findings include:
- Agricultural intensity increased significantly over this period, with the most intensive agriculture replacing natural vegetation.
- Tree cover declined overall but herbaceous vegetation declined more than tree cover. Managed trees on farms increased.
- Land tenure impacted land use patterns - adjudicated land had more intensive agriculture and greater tree cover compared to unadjudicated land.
- Population growth and expansion of agriculture led to encroachment into forest reserves like Mau Forest. Agricultural intensity varied between agro-ecological zones and was influenced by rainfall and temperature.
Effects of temperature on potato crop

Grasslands
Grasslands are lands covered primarily by grass and used for agriculture like growing wheat, corn, and grazing livestock. They have fertile soil and support grazing animals but have few trees. Grasslands are used for farming and raising livestock.
Integrated farming system
This document describes several integrated farming systems models across different agro-climatic zones in India. The key components are crop production, livestock rearing (poultry, fish, dairy), and use of byproducts between components to improve economic returns and employment generation compared to conventional systems. Specific models integrate rice, fish and poultry production; include crops, dairy and biogas; and combine tree crops, grass, and goat rearing for dryland areas. On average, integrated systems provide higher net profits and more employment than conventional cropping alone.

agriculture status of ladakh
Agriculture is important for Ladakh given its changing dietary needs and tourism industry. Currently about 775 hectares are used to cultivate over 78 types of vegetables, yielding over 103,000 quintals annually. Challenges include harsh climate, poor irrigation, lack of high-yielding varieties, and marketing and storage issues. With protected cultivation, micro-irrigation, and focus on high-value crops, Ladakh could boost production and exports to meet local demands.
Protected cultivation and secondary agriculture.pptx
This document discusses protected cultivation and secondary agriculture in India. It notes that India has diverse climates but vegetable cultivation is restricted regionally and seasonally due to temperature and biotic stress extremes. Protected cultivation using structures like greenhouses, tunnels and mulches can help overcome these challenges by controlling the environment to allow year-round production. It describes different types of protected structures from basic low tunnels to high-tech greenhouses and their uses. It also outlines the current status, advantages, constraints and future prospects of protected cultivation in India.
AGRICULTURAL MECHANISATION IN THAILAND
Thailand has experienced rapid agricultural mechanization since the 1960s driven by smallholder demand and domestic manufacturing. The first wave involved affordable, small-scale machines like pumps and two-wheeled tractors owned by smallholders. The second wave included larger contractor machines. Mechanization was spurred by labor shortages from industrialization, migration, and falling birth rates. It has spread widely due to fertile soils, irrigation, double-cropping, and adaptable local manufacturers producing affordable machines suited to small farms. Thailand's agricultural mechanization has largely benefited smallholders through machine ownership or hiring services.

This document summarizes a study that investigated different cooling methods for greenhouses growing tomatoes in a Mediterranean climate. Three greenhouses used different cooling systems: one used fogging and natural ventilation (Fog+NV), one used fans and evaporative pads (FP), and one used only natural ventilation (NV). Temperature, humidity, plant growth, and tomato yields were compared between the greenhouses over three growing periods. The results showed that the FP system was most effective at reducing high temperatures, maintaining optimal growing conditions, and increasing tomato yields compared to the other systems. Yields were highest with FP, followed by Fog+NV, and lowest with NV alone. Therefore, properly designed FP cooling systems can improve tomato production in hot Mediterranean clim

This document discusses a study on the effects of planting date and planting method on wheat yield in Nigeria. The study tested four planting dates (1st November, 15th November, 1st December, 15th December) and three planting methods (drilling, dibbling, broadcasting) in two locations. Results showed that later planting dates of 15th November and 1st December produced higher grain yield compared to earlier dates. Drilling and dibbling methods also resulted in higher yields than broadcasting. Based on these results, the study concludes that planting wheat from 15th November to 1st December using drilling or dibbling is best suited for the study areas.Protected ariculture: A production system for arid rehgions
This document discusses protected agriculture as a production system suitable for arid regions. It describes the environmental constraints of arid zones like low and erratic rainfall, high temperatures, and scarce water resources. Protected structures like greenhouses, net houses, and low tunnels are recommended as they provide favorable growing conditions, higher yields, and more efficient water and input use compared to open field cultivation. Specific techniques for different crops like tomato, cucumber, and capsicum within these protected structures are covered, including variety selection, seedling raising, transplanting, training, fertigation practices, and more.

High tunnel basic state conference 2012
- High tunnels are unheated structures that resemble greenhouses and allow crops to be grown earlier and later than outside by utilizing the natural heat gain inside the structure. They provide advantages like earlier and later production, higher yields, natural pest and disease control.
- Crops that can be grown include vegetables normally grown in the region like tomatoes, peppers, cucumbers, which produce earlier and have higher yields inside high tunnels.
- Key components of high tunnels include good drained soil, roll up sides, UV treated plastic covering, and can be built from various materials like wood or metal frames. High tunnels take advantage of the principles of plant growth related to time, heat and light to extend the growing season

Uae watergy 09_15
The document discusses a new type of greenhouse called Watergy, which uses internal air circulation to achieve high water recovery and crop yields. A prototype in Al Dhaid demonstrated 85% water recovery and increased CO2 levels and pesticide-free cultivation. However, challenges remain regarding costs, temperature control at night and during hot days, and limited dehumidification. Various methods are proposed to improve temperature differences for heat transfer, store heat between day and night, transport air and storage media, and apply condensed water and brine for desalination and other uses.
Report on protected agriculture bahrain
The greenhouse industry in Bahrain has grown significantly since the first greenhouse was constructed in 1978. By 2000, greenhouses were widely adopted by farmers. Tomatoes, peppers, cucumbers and lettuce are the most common crops grown in greenhouses. While yields have increased, many farmers still do not use climate control systems like cooling due to high costs and water constraints. The government provides some subsidies to support greenhouse farming. Future plans include promoting more advanced growing systems and the use of renewable energy in greenhouses.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
