Technological advances in agriculture helped increase food production through the Green Revolution of the 1960s. Key aspects included high-yielding crop varieties, fertilizers, pesticides, improved irrigation, and mechanization. However, overuse of these technologies can cause environmental issues like waterlogging, salinization, and eutrophication. While genetically modified crops provide benefits, they also pose uncertainties and risks to biodiversity, health, and small farmers. Food shortages result from physical factors like climate change and extreme weather; political issues such as civil strife and poor governance; economic challenges including rising food demand and costs; and social problems like lack of access, distribution difficulties, and rapid population growth. Technology alone cannot solve food insecurity—

A lecture in Quantitative Sustainability
It is often claimed that agricultural productivity needs to be increased in order to feed a growing world population. Food security depends on several factors besides the productivity, including waste/efficiency, energy crops, meat consumption, and global justice and equity. This lecture explores the issue of food security in its many dimensions and teaches how to use a high-level systems approach in sustainability science.
"The world's 200 wealthiest people have as much money as about 40% of the global population, and yet 850 million people have to go
to bed hungry every night."
Hugo Chavez, Venezuela’s socialist president: “The problem is not the production of food … it is the economic, social and political model of the world. The capitalist model is in crisis.”
With unemployment reaching record levels, the demand for food from food banks have also reached new highs. The report gives a detailed overview of Feeding America, the largest hunger relief organization in the United States and the challenges facing food banks at a time when its needed the most.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
2. Technological advances
• Green Revolution
– The use of technology to increase productivity of
agriculture.
– Started in the 1960s.
– Key success is in the Less Developed Countries
(LDCs).
– 4 key pushes
• High-yielding varieties
• Fertilisers and pesticides
• Improved irrigation
• Mechanisation
3. HYV varieties
• Strains of crops with increased growth rate.
• Developed through cross-breeding of selected
varieties
• Bred for favourable characteristics.
– Resistance to pests and diseases
– Short growing season.
– ‘wonder rice’ - 100 day rice
– IR8 (HYV rice) promoted across Asia, success in
India.
4. Fertilisers
• Substances added to provide nutrients.
• Solution to soil nutrient depletion.
–Commercial farms do not have allowance
for fallow
–Land is not allowed to recover
• Fertilisers reinstate the nutrient in the
soil, helping the crop yield of HYV.
• Costly
5. Pesticides
• Chemicals to kill insects and small animals
(pests).
• Herbicides kill weeds (plants).
• Large amount of pests / weeds can decimate
complete yields.
• Use of Pesticides and Herbicides will help
maintain the crop yield.
6. Irrigation
• Manmade supplying of water to land.
• Introduction of water to arid areas
– Areas with minimal water supply
• Increased arable land worldwide
• Reclaiming desert areas as agricultural land
– Libya, Great Man-made River.

7. Mechanisation
• Used of advanced machinery to perform
manual tasks.
• Speeds up processes
• Increases efficiency
• Reduces reliance on human labour.
• Combined Harvester, Planes, etc.

8. Genetically modified food (GM)
• Food crops that have been genetically modified.
• Genes are selected based on predetermined
criteria.
• Transplanting of genetic material from different
organisms.
• Search for positive characteristics that would
assist in :
– Faster rate of growth
– Better quality of product
9. 2 stages of GM food development
HYV crops (1960s – present) GM crops (1990s – present)
Method of
development
• Cross-breeding • Alternation of genes
Benefits • Shorter growing season
• Resistant to pests and
diseases
• Shorter growing season
• Resistant to pests and diseases
• Resistant to extreme weather
conditions
• Health benefits
Examples • Super rice
• Wonder rice
• FlavrSavr Tomato
• Golden Rice
• BT-cotton
• BT-corn
11. Effects of continuing intensification of
food production?
• Intensification of food production brings
many benefits.
• It increases the total amount of food
produced.
• With extended intensification, there is also
large scale environmental damage.
• Waterlogging – situation where too much
water seeps into the soil and cause the soil
to be over-saturated. Roots drown.
12. Salinisation
• Water added during irrigation evaporates and
leaves salt behind.
• With insufficient drainage of excess water,
groundwater rises and brings up dissolved
salts.
• Victoria, Australia. Combination of tree
clearing and irrigation led to salinisation of
farmland.
13. Eutrofication
• Presence of excess nutrients in water leading
to algae bloom.
• Algae depletes oxygen and blocks sunlight
from aquatic plants.
• Large scale death of aquatic plants and
organisms.
• Decomposition of aquatic organisms lead to
further depleting of oxygen.
14. Measures to reverse eutrophication
• Control measures to prevent nutrients from
reaching the water bodies.
– Runoff management, use of hard engineering
measures to prevent runoff from reaching the
water bodies.
• Raising awareness through education
– Education in schools and public education
campaign.

16. Consequences of development of
GM crops
• Long-term impact on human health unknown.
• Cultivation of GM crops restricted in some
countries like Peru.
• Most countries require clear labelling for
products made from GM crops.
• Some countries ban the sale of GM crops.
17. Benefits GM crops bring
• Increased income for farmers
–GM increases productivity
–Pest resistant crops save money on
pesticides
–Higher crop yield brings higher
income.
•BT-cotton

Corn!
18. Nutritional benefits
• GM allows for modification to have
higher nutrition.
• Golden Rice (higher Vitamin A)
• Able to help reduce blindness.
• Large nutritional benefit for LDCs.
19. Decreased Environmental Pollution
• GM crops reduce dependence on chemical
pesticides.
• Reduce the potential of environmental
pollution.
• BT Corn’s minimal reliance on pesticide sprays.
20. Threats of GM crops
• Dominance of agribusiness
–GM crops require high capital inputs
–Large companies are more able.
–Small scale farmers unable to afford
the GM seeds and techniques.
–Small scale farmers cannot enjoy the
benefits.
21. Potential Health Risks
• Unknown effects on human health as
a result of genetic engineering.
• Concern over triggers of allergic
reactions due to the change in the
genetic composition of the crops.
22. Loss of biodiversity
• Success of GM crops harm other organisms.
• Transfer of pest resistance to wild varieties
lead to extinction of insects and animals that
feed on wild species.
• Monarch butterfly caterpillars die from eating
milkweed that were contaminated with pollen
from BT corn.
23. Causes of food shortages
• Physical factors
– Extreme Weather conditions, Climate change, Pests
• Political factors
– Civil strife, Poor governance
• Economic factors
– Demand from emerging economies, food policy, rising
costs
• Social factors
– Lack of accessibility, Bad logistics and distribution,
Population explosion.
25. Climate Change
• Change in weather patterns and global
climate affect growing season and crop
yield.
• Previously arable areas no longer
suitable.
• Loss of glacial ice reduces freshwater
supply for river basins globally.
–Agricultural land dependent on these will
dry up.
26. Extreme weather events
• Droughts, cold waves, heat waves,
tropical cyclones.
• Lead to destruction of crops, farmland
and potential food shortage.
• Extreme weather events more common
due to climate change.
27. Pests
• Rising global temperatures encourage
growth of pests.
• Swarms of pests increase to larger
quantities.
• Locusts swarms and Caterpillar invasions.
29. Civil Strife
• Country faces major internal conflicts.
• Riots, unrest, or civil war.
• Disputes over control of resources.
• Reduction of food production.
– Farmland loss to war and conflict are unable to
contribute to production.
30. Poor Governance
• Corruption, policy errors and inability
to implement policy causes food
shortages.
• Prioritising other developmental
needs over ensuring food security
leads to re-allocation of farm land to
other functions.
32. Demands from emerging economies
• Rise of large LDCs (Brazil, Russia, India and
China BRIC).
• Increase in size and affluence leads to increase
in demand for food products.
• Larger demand leads to food shortages in
poorer countries.
33. Food Policy
• Governments use stockpiles to
ensure food security.
• However stockpiling may lead to
price rises.
• Reduction in global supply lead to
shortage for LDCs.
34. Food subsidies
• Money paid or tax deductions to make food
affordable.
• Countries with substantial economic reserves
able to use it to help citizens.
• Countries who are not rich enough to provide
subsidies will have large populations facing
food shortage.
35. Spike in fertiliser and transport costs
• Sudden rises in production costs lead to price
spikes of food.
• Without corresponding rise in income lead to
poverty and food shortages.
36. Loss of farmland
• Growing industrial crops leading to loss of
food crops
• Switch to biofuels lead to increase demand for
land for biofuel crops.
• Higher price of biofuel crops trigger shift from
food crop to biofuel crops.
38. Lack of accessibility
• Lack of transport facilities hinder accessibility
to food.
• Location and quantity of food outlets also
affect the accessibility of food.
• Inability to access fresh produce leads to a
smaller food intake.
39. Food distribution
• The movement of food from farm to retail
outlets.
• Dependent on good transport network.
• Physical barriers and natural disasters can
disrupt distribution patterns and reduce the
food supply.
40. Rapid population growth
• Population growth is exponential
• Food production increment is unable to catch
up without technological advances.
• Larger population leads to further need for
land and reduction in existing farmland.
• Sub-Saharan Africa is at highest risk.
41. Is technology in food production the
solution?
• Current global food production exceeds global
needs.
• Many areas are still suffering from shortages.
• Technology is one part of the solution, other
factors need to be managed.
42. Summary
• People in DC and LDCs have different levels
and types of food consumption patterns.
• Food consumption patterns are influenced by
economic, socio-cultural and political factors.
• Inadequate food consumption leads to
malnutrition and starvation.
• Excess food consumption and choice of diet
may lead to obesity, lower productivity, food
wastage and dieting.
