In-depth Study of the Pluralistic Agricultural Extension System in India
This In-Depth Study of the Pluralistic Agricultural Extension System in India is a full analysis of the pluralistic extension system in India, how it has changed over many years and the direction it is currently moving.
Chapter-1 outlines the Evolution of the Pluralistic Agricultural Extension System in India and the changes that have occurred since about 1871, including the establishment of the Department of Agriculture in 1882. Following independence in 1947, many changes have happened as outlined in this first chapter, including the Community Development Program (CDP), the Intensive Agricultural District Program (IADP), including dissemination of high-yielding varieties during the Green Revolution, the Training and Visit (T&V) approach and then the move to the decentralized, farmer-led and market driven approach influenced by the Agricultural Technology Management Agency (ATMA) model.
Chapter-2 gives an Overview of the Public Extension System within the Ministry of Agriculture (MoA), the State Departments of Agriculture and then provides more detailed information about the Krishi Vigyan Kendra (KVK) and the public extension system in India. It starts with an overview of the organizational structure at the national level, including the Department of Agricultural Research and Extension (DARE), then into the Department of Agriculture and Cooperation (DAC) and Directorate of Extension within DAC. Then, it moves into the KVKs, which are a critical linkage at the district level between research, extension and farmers. In short, KVKs focus on the specific agro-ecological conditions within each district and then, after conducting research on these different crops, livestock and other farming systems. Then it moves into the development of the ATMA model through two World Bank projects, which is now expand across all Indian districts.
Chapter-3 outlines the Directorates of Extension Education within each State Agricultural Universities (SAUs). India is unique in having Extension units established within each SAU, since this extension approach was first introduced by selected US Land Grant Universities into these SAUs in the late 1950s and early 1960s. This chapter outlines the historical development of the extension within each SAU and then outlines the mandate, organizational structure, human resources and methods used within these SAUs and their relationship with the public extension system.
Chapter-4 outlines the Private Sector Advisory Services being provided in India, especially in the provision of good advisory services through private Agri-Business Companies through the sale of inputs to farmers. In India, there are over 280,000 input supply firms, but many do not have sufficient knowledge and experience in providing good advisory services to farmers. At first, the public and private sector did not want to work together but through the ATMA approach, the public and private sector started working together and then, in 2004, the National Institute of Agricultural Extension Management (MANAGE) started training and giving diplomas to the participants from these private sector firms, especially in Andhra Pradesh (see: http://www.manage.gov.in/daesi/daesi.htm).
Chapter-5 summarizes the role and activities of the different Commodity Boards currently operating in India, including: Central Silk Board (CSB), Coconut Development Board (CDB), Coffee Board, Coir Board, Rubber Board, Spices Board, Tea Board, Tobacco Board, National Dairy Development Board (NDDB), National Horticulture Board (NHB), Cashew Export Promotion Council (CEPC), National Jute Board (NJB), and the National Federation of Cooperative Sugar Factories (NFCSF) and how each of these boards carry out extension and advisory services to the farmers being served.
Chapter-6 outlines the Institutional Mechanism for Capacity Building to strengthen the pluralistic extension system in India. This chapter starts with an overview of the National Institute of Agricultural Extension Management (MANAGE), which is an autonomous organization that has had the most impact on strengthening the extension system in India. Next, it discusses the paradigm shift within the National Institute of Agricultural Marketing (NAIM) in India; and then outlines the role of the Extension Education Institutes (EEIs). Finally, it moves to outline the role and structure of the State Agricultural Management and Extension Training Institutes (SAMETIs), especially in strengthening the ATMA model in India.
Chapter-7 is the conclusion chapter that outlines the Strengths and Weaknesses of India’s Pluralistic Extension System. It starts by outlining the Policy Framework and Reforms for strengthening the pluralistic extension system in India. Next, it outlines how to strengthen research-extension linkages as well as capacity building among extension workers. Next, it addresses how to empower farmers, including women farmers. It also outlines the use of Information Technology (IT) and how to strengthen it through different approaches. This chapter also outlines the changing role of government in extension and how the ATMA model can be strengthened following very specific details. The other issue is how to strengthen the SAMETIs, since they still need to be strengthened in providing service to district and block level extension workers. This chapter ends with a brief summary the key role that the public extension system can play in India

Pre-main-sequence Lithium Depletion
In this review I briefly discuss the theory of pre-main-sequence (PMS) Li
depletion in low-mass (0.075<M<1.2 Msun) stars and highlight those uncertain
parameters which lead to substantial differences in model predictions. I then
summarise observations of PMS stars in very young open clusters, clusters that
have just reached the ZAMS and briefly highlight recent developments in the
observation of Li in very low-mass PMS stars.Comment: 8 pages, invited review at "Chemical abundances and mixing in stars

A Model for the Development of the Rhizobial and Arbuscular Mycorrhizal Symbioses in Legumes and Its Use to Understand the Roles of Ethylene in the Establishment of these two Symbioses
We propose a model depicting the development of nodulation and arbuscular mycorrhizae. Both processes are dissected into many steps, using Pisum sativum L. nodulation mutants as a guideline. For nodulation, we distinguish two main developmental programs, one epidermal and one cortical. Whereas Nod factors alone affect the cortical program, bacteria are required to trigger the epidermal events. We propose that the two programs of the rhizobial symbiosis evolved separately and that, over time, they came to function together. The distinction between these two programs does not exist for arbuscular mycorrhizae development despite events occurring in both root tissues. Mutations that affect both symbioses are restricted to the epidermal program. We propose here sites of action and potential roles for ethylene during the formation of the two symbioses with a specific hypothesis for nodule organogenesis. Assuming the epidermis does not make ethylene, the microsymbionts probably first encounter a regulatory level of ethylene at the epidermis–outermost cortical cell layer interface. Depending on the hormone concentrations there, infection will either progress or be blocked. In the former case, ethylene affects the cortex cytoskeleton, allowing reorganization that facilitates infection; in the latter case, ethylene acts on several enzymes that interfere with infection thread growth, causing it to abort. Throughout this review, the difficulty of generalizing the roles of ethylene is emphasized and numerous examples are given to demonstrate the diversity that exists in plants

Global, regional, and national comparative risk assessment of 79 behavioural, environmental and occupational, and metabolic risks or clusters of risks, 1990-2015: A systematic analysis for the Global Burden of Disease Study 2015
Background: The Global Burden of Diseases, Injuries, and Risk Factors Study 2015 provides an up-to-date synthesis of the evidence for risk factor exposure and the attributable burden of disease. By providing national and subnational assessments spanning the past 25 years, this study can inform debates on the importance of addressing risks in context.
Methods: We used the comparative risk assessment framework developed for previous iterations of the Global Burden of Disease Study to estimate attributable deaths, disability-adjusted life-years (DALYs), and trends in exposure by age group, sex, year, and geography for 79 behavioural, environmental and occupational, and metabolic risks or clusters of risks from 1990 to 2015. This study included 388 risk-outcome pairs that met World Cancer Research Fund-defined criteria for convincing or probable evidence. We extracted relative risk and exposure estimates from randomised controlled trials, cohorts, pooled cohorts, household surveys, census data, satellite data, and other sources. We used statistical models to pool data, adjust for bias, and incorporate covariates. We developed a metric that allows comparisons of exposure across risk factors—the summary exposure value. Using the counterfactual scenario of theoretical minimum risk level, we estimated the portion of deaths and DALYs that could be attributed to a given risk. We decomposed trends in attributable burden into contributions from population growth, population age structure, risk exposure, and risk-deleted cause-specific DALY rates. We characterised risk exposure in relation to a Socio-demographic Index (SDI).
Findings: Between 1990 and 2015, global exposure to unsafe sanitation, household air pollution, childhood underweight, childhood stunting, and smoking each decreased by more than 25%. Global exposure for several occupational risks, high body-mass index (BMI), and drug use increased by more than 25% over the same period. All risks jointly evaluated in 2015 accounted for 57·8% (95% CI 56·6–58·8) of global deaths and 41·2% (39·8–42·8) of DALYs. In 2015, the ten largest contributors to global DALYs among Level 3 risks were high systolic blood pressure (211·8 million [192·7 million to 231·1 million] global DALYs), smoking (148·6 million [134·2 million to 163·1 million]), high fasting plasma glucose (143·1 million [125·1 million to 163·5 million]), high BMI (120·1 million [83·8 million to 158·4 million]), childhood undernutrition (113·3 million [103·9 million to 123·4 million]), ambient particulate matter (103·1 million [90·8 million to 115·1 million]), high total cholesterol (88·7 million [74·6 million to 105·7 million]), household air pollution (85·6 million [66·7 million to 106·1 million]), alcohol use (85·0 million [77·2 million to 93·0 million]), and diets high in sodium (83·0 million [49·3 million to 127·5 million]). From 1990 to 2015, attributable DALYs declined for micronutrient deficiencies, childhood undernutrition, unsafe sanitation and water, and household air pollution; reductions in risk-deleted DALY rates rather than reductions in exposure drove these declines. Rising exposure contributed to notable increases in attributable DALYs from high BMI, high fasting plasma glucose, occupational carcinogens, and drug use. Environmental risks and childhood undernutrition declined steadily with SDI; low physical activity, high BMI, and high fasting plasma glucose increased with SDI. In 119 countries, metabolic risks, such as high BMI and fasting plasma glucose, contributed the most attributable DALYs in 2015. Regionally, smoking still ranked among the leading five risk factors for attributable DALYs in 109 countries; childhood underweight and unsafe sex remained primary drivers of early death and disability in much of sub-Saharan Africa.
Interpretation: Declines in some key environmental risks have contributed to declines in critical infectious diseases. Some risks appear to be invariant to SDI. Increasing risks, including high BMI, high fasting plasma glucose, drug use, and some occupational exposures, contribute to rising burden from some conditions, but also provide opportunities for intervention. Some highly preventable risks, such as smoking, remain major causes of attributable DALYs, even as exposure is declining. Public policy makers need to pay attention to the risks that are increasingly major contributors to global burden.

Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.
BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.
