On NOT finding the world's next superfood
Ann Tutwiler, Director General, Bioversity International presentation on NOT finding the world's next superfood. This presentation was delivered at Kew Gardens on May 12th 2016 at the State of the World's Plants Symposium.
Abstract: In the last few years, superfoods such as quinoa, amaranth and goji berries have been celebrated in the international media in recognition of their rich nutrient content.
But it is not just Western consumers that can benefit from rediscovering these forgotten foods.
M. Ann Tutwiler, Director General, Bioversity International, will explain how many nutritious traditional foods, which have largely fallen off menus and research-for-development agendas in favour of a handful of staple grains, are starting to make a comeback on the plates of the world’s poorest and most malnourished populations.
Bioversity International carries out research on a diverse range of underutilized crops, and advocates for their wider use in healthy diets from sustainable food systems. This overview will include examples of how research-for-development efforts on quinoa in the High Andes and minor millets in India have helped bring diverse varieties back to the farm, the market and the plate. She will highlight how these crops are often not just nutrient-rich but also have a high potential to contribute to livelihoods. They are often also highly resilient to today’s production challenges, such as climate change.

This document summarizes three cereal crops - barley, millet, and maize - and their main diseases. For barley, it describes powdery mildew, covered smut, and loose smut, including their pathogens and symptoms. For millet, it discusses green ear/downy mildew, grain smut, and ergot. And for maize, it covers smut, common rust, and anthracnose leaf blight, providing details on each disease's pathogen and symptoms. Control methods mentioned include using resistant varieties, fungicide seed treatment, spraying fungicides, field sanitation, and crop rotation.
Plant Diseases
Rust is a fungal disease that infects a wide range of plant species. It has a complex life cycle involving 5 spore-producing stages and usually requires two different host plants. Common rust symptoms include yellow or rust-colored spores produced in pustules on leaves and stems. Disease management focuses on using resistant varieties and fungicide application when needed.
PLANT DISEASE CONTROL
This document discusses various methods for controlling plant diseases. The major methods discussed are cultural control methods, biological control methods, and chemical control methods. Cultural control methods include avoiding contact between the pathogen and host plant through proper field selection, resistant varieties, and modifying cultural practices. Biological control uses other organisms like fungi, bacteria, and mycorrhizal fungi to control pathogens. Chemical control involves the use of fungicides, bactericides, and other chemical treatments to directly kill or inhibit pathogens.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems
9
Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
