Integrated Farm Management Practices and Upscaling the Impact for Increased Productivity of Rainfed Systems
Full text linkMost countries in the world depend primarily on
rainfed agriculture for their food grains. Despite
large strides made in improving productivity and
environmental conditions in many developing
countries, more than 850 million poor people in
Africa and Asia still face poverty, hunger, food
insecurity and malnutrition, where rainfed agriculture
is the main agricultural activity. Although
the importance of rainfed agriculture varies
regionally, it produces most food for poor
communities in developing countries (Rockström
et al., 2007; also see Chapter 1, this volume).
These problems are exacerbated by adverse
biophysical growing conditions and the poor
socio-economic infrastructure in many areas in
the semi-arid tropics (SAT). The SAT is home to
38% of the developing countries’ poor, 75% of
whom live in rural areas. Over 45% of the world’s
hungry and more than 70% of its malnourished
children live in the SAT
Bhoochetana: Mission to Boost Productivity of Rainfed Agriculture through Science-led Interventions in Karnataka
Full text linkRole and contribution of rainfed areas in food production has been quite significant.
Eighty per cent of the cultivable area in the world and population is dependent on rainfed
agriculture. Major share of food production ie., about 60% comes from rainfed agriculture.
Area under rainfed agriculture in India is 85 million ha. contributing to 44% National food
production. Similar situation more or less exists in Karnataka. Out of total cultivated area
of 123.85 lakh ha., about 70% of the area is rainfed.
Major rainfed crops of the State are jowar, ragi, maize, minor millets, groundnut, sunflower,
soybean, tur, green gram, black gram, Bengal gram, and field bean etc. It has been
observed that the average yields of these crops by and large in the State are less than the
national average and also averages of other States. Further a wide gap exists in actual
yield levels in the farmer’s field and yields of field level demonstrations.
There is an opportunity to enhance yield levels in the fields of farmers by two to three folds
through adoption of suitable improved dryland technologies for various crops. Based on
the research findings of ICRISAT, Hyderabad, and demonstrations conducted under Sujala
Watershed Programme; a set of dryland technologies have been identified by ICRISAT,
Hyderabad for increasing yields to an extent of minimum 20%. Encouraged by this, and
also with a view to enable farmers to get better yields in their fields, the Government of
Karnataka initiated an novel scheme called Bhoochetana during 2009–10......
Nutrient Deficiencies and their Management in Soils of the Semi-Arid Tropical Regions
Full text linkIn the semi-arid tropics (SAT) regions, the loss of soil, organic matter, and nutrients are of great concern. Nutrient imbalance in the case of major plant nutrients has been reported for a long period of time as a result of decline in soil organic carbon status in the rainfed areas of Asia and Sub-Saharan Africa. In India, the results of analysis of a large number of soil samples collected from farmers fields in Andhra Pradesh, Karnataka, Madhya Pradesh and Rajasthan, showed that the samples were low in organic carbon, low to medium in available phosphorous (P), medium to high in potassium (K), low in sulphur (S), boron (B) and Zinc (Zn)
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Sustainable Intensification of Rainfed Agriculture through Natural Resource Management: Proceedings of Tata-ICRISAT-ICAR and Model Watershed Projects’Review and Planning Meeting
Full text linkCommunity watershed management for sustainable intensification in Northeast Thailand
Full text linkAgriculture is the main occupation in Thailand and it plays an important role in
the economic development of the country. Thailand is located in the tropical
monsoon climate region where the amount of rainfall is high but shortage of
water occurs even in rainy season. Only 20% of total agricultural area is under
irrigation, with rest constituting rainfed area, which has relatively lower crop
yields. High soil erosion and reduced soil productivity are some of the problems
in the rainfed area
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
