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

3. Two Key Challenges Facing
Africa’s Dryland Smallholders
• Rainfall Variability: Rainfall variability is a greater
challenge than absolute amount of rainfall
• Weathered Soils: Over 80% of Africa’s soils have
major productivity constraints (Breman, et.al, 2007)
– Naturally low in nutrients
– Low capacity to retain nutrients Benefits of
mineral fertilizers marginalized
Both of these challenges have been addressed at

For much of Africa, evidence shows the following:
• A high correlation between productivity and
resilience and
– Rainfall capture
– Soil organic matter levels.
• Best results achieved from using external inputs
(fertilizer, improved seed) in tandem with sound
soil and water management practices.
• Diverse farming systems are typically more
productive and resilient than single crop systems
• In many places in the Sahel, helplessness has
been replaced by hopefulness
Editor's Notes
My job will be to set the stage for Chris, Gray, Emmy and Bob. I will be talking first about what the science and experience says about the challenges facing Sahelian farmers and , secondly about Regreening technologies that have helped them these challenges
First, what is Regreening? It is characterized by farmers investing in better management of soils, water and vegetation. Examples include: Rainfall harvesting technologies in Burkina Faso, Niger and Mali, and Agroforestry systems in West and East Africa As you can see, many of these have been adopted at a broad scale.
To understand the importance of Regreening technologies, let’s look at challenges shared by most African dryland farmers. They include: High rainfall variability, which is often more of limiting factor than the absolute amount of rainfall and Weathered soils. Africa is an old continent and more than 80% of its soils have significant productivity constraints including: Being low in nutrients and Having little natural capacity to retain nutrients applied in fertilizers. .
In facing climatic changes, farmers can expect the following: More intensive rainfall events, meaning more run-off; Longer intervals between rainfall events, meaning loss of early-season crops; Changing rainfall patterns (e.g., late start in the rainy season) meaning more frequent crop failures. However, there is a proven track record in addressing these challenges.
For example, ridge tillage is one of several technologies used by farmers to hold rainfall where it falls allowing it to infiltrate the soil. Other rainfall management technologies include “zai’s”, contour dikes, half-moons, etc. Research on ridge tillage by Malian and US Scientists showed the following results: 66% increase in rainfall infiltration 17% more soil moisture at the end of the season, and 30% increase in fertilizer-use efficiency—which I will address later. The above results contributed to a 30-50% yield increase.
In addition, ridge tillage recharged the water table which: Allowed farmers to establish dry-season irrigated gardens, and Increased productivity of high-value field trees
These secondary benefits not only provided new and additional sources of revenue and nutritious food, but, because they were less susceptible to climatic variability, they reduced farmers’ risks and increased resiliency.
Moving to the challenges of weathered soils, this graph shows the importance of soil management to fertilizer-use efficiency and productivity. This research, conducted on sorghum fields in Burkina Faso, compared two treatments: One with additions of both fertilizer and organic matter and one with fertilizer and removal of organic matter. The control received no fertilizer. As can be seen, in the first year both treatments produced significant yield increases and maintained those increases for several years. But, around year 12, the response of the Fertilizer Only treatment went into a steady decline until, by year 15, yields were back to the control levels. This indicated no response to the fertilizer being applied. At the same time, the fields that received organic matter maintained a high-yield response to fertilizer. The reason for this difference is that organic matter provided the soil, which was likely weathered, with increased capacity to retain nutrients. A lesson here is that on many African soils, applying fertilizer without maintaining adequate soil organic matter levels will produce marginal returns.
However, amending the soil’s organic matter content is an arduous task if the organic matter has to be carried to the field. But, a growing number of dryland farmers amend their soils through various forms of agroforestry systems which drop tons of litter per hectare yielding a continual and convenient source of organic matter. Consequently, agroforestry farmers should expect higher returns and less risk from investments in fertilizers and improved seed.
In addition to increasing soil productivity, these systems are less susceptible to climatic variability. Even in a poor or erratic rainy season where annual crops do poorly or fail entirely, the farmer will be able to harvest wood, browse, gum, oils, pharmacopeia, etc. will not have the catastrophic impact on tree products as on annual crops.
These new production systems appear to have had an intangible impact on people’s attitudes. Recalling that the 1970’s were marked with a feeling of helplessness, I think that we are now seeing large pockets where people feel that they have more control in being able to do something in the face of climatic and land challenges. While a small sample, this research showed that people that practiced agroforestry were more optimistic than those who did not. Given that this survey was published in the year following the 2005 Food Crisis in Niger might give it additional weight.
Given that we are focusing on crop production, I wanted to provide illustrative ranges of yields and resiliency levels from various systems. These are based upon specific research findings, but I wish to emphasize that they are illustrative. Given that provision, I would like to make the following points: To address food security challenges in the long run, farmers will need to achieve the higher yields on this table. While “regreening-only” will provide substantial increases over “no-treatments,” will help farmers buy time, and strengthen resiliency, the yields will need to be higher. While external inputs-only will provide initial yield increases, they will need to be accompanied by better soil and water management to be sustained. And, they will provide little resiliency. In sum, achieving the necessary yields and strengthening resiliency will require external inputs used in tandem with Regreening systems.
