In Box 142 It Says That New Varieties Were Introduced To Solve An

In Box 14.2 it says that “new varieties were introduced to “solve” an increasing number of disease and pest problems that would have caused wheat yields to decline substantially in the absence of the new varieties.” Research, and dollars spent for research on disease and pest resistance has declined markedly in the past 25 years. My question is: should we be more concerned than we are with the possibility that a new strain of a disease might wipe out, or substantially reduce crop yields some day in the near future? Are we ahead of the game with today’s research and innovations and with biotechnology, or should we be worried? I would like you to do a web search of “potential crop diseases” and write your opinions of whether or not you think we should worry, and why. Cite your source(es) and respond to another person.

The ongoing challenges faced by agriculture, particularly the threat of emerging crop diseases, demand careful consideration. Historically, the development of new crop varieties was a crucial strategy to combat pest and disease issues, as highlighted in Box 14.2, which notes that these varieties were introduced to prevent significant declines in wheat yields. However, over the past 25 years, investment in research on disease and pest resistance has declined markedly, raising concerns about our preparedness for future threats. This essay explores whether current research and technological innovations, especially in biotechnology, are sufficient to mitigate the risks posed by potential new crop diseases and whether we should be more worried about these threats.

Historically, agricultural resilience has depended heavily on the development and deployment of disease-resistant crop varieties. In the early 20th century, such efforts led to the eradication or significant control of devastating diseases like wheat rust and potato blight (Wale et al., 2018). The Green Revolution further emphasized breeding disease-resistant crops, resulting in dramatic increases in productivity (Evenson & Gollin, 2003). Nonetheless, the threat of new or evolving diseases remains an ongoing risk, especially with climate change and global trade facilitating the rapid spread of pathogens (Liu et al., 2020). The concern is that if new strains of pathogens emerge that bypass existing resistance, crop yields could be severely compromised.

In recent decades, advances in biotechnology have added new dimensions to disease management. Genetically modified organisms (GMOs) with built-in pest and disease resistance, such as Bt cotton and virus-resistant papaya, demonstrate the potential of biotechnology to enhance crop resilience (James, 2017). CRISPR gene-editing technology further offers promising avenues for developing crops that can resist emerging threats quickly and more efficiently (Jaganathan et al., 2018). These technological innovations suggest that we are better equipped than ever before—yet, the decline in funding and research initiatives for disease resistance could undermine this capacity.

The decrease in research funding, as noted in the prompt, is concerning because it limits our ability to adapt rapidly to new threats. According to the National Academies of Sciences, Engineering, and Medicine (2019), sustained investment in agricultural research is vital for maintaining crop resilience in the face of evolving pathogens. Furthermore, the unpredictability of pathogen evolution means that existing resistance can be overcome swiftly, emphasizing the need for continuous research and development. For instance, the emergence of new strains of wheat stem rust, like Ug99, exemplifies how quickly a pathogen can evolve and threaten global wheat supplies (Singh et al., 2014).

Web searches on "potential crop diseases" reveal a multitude of emerging threats. For example, the spread of wheat blast in South America and Africa, caused by Magnaporthe oryzae, has raised alarms regarding the potential devastation of wheat crops (Ceresini et al., 2019). Similarly, the appearance of new viral diseases like the tomato brown rugose fruit virus has impacted vegetable crops globally (CDC, 2021). With climate change, the geographical range of many diseases is expanding, creating more opportunities for outbreaks. This trend underscores the importance of proactive research and innovation, including the development of resistant crop varieties using cutting-edge biotechnology.

Given these considerations, should we be worried? The evidence suggests that we should remain vigilant. While current research and biotechnological advances provide valuable tools, declining funding and the rapid evolution of pathogens threaten to outpace these efforts. The history of agriculture has repeatedly shown that pathogens can evolve quickly, rendering existing resistant varieties ineffective. Therefore, a proactive approach with sustained investment in research, combined with advanced biotechnology, is essential. Moreover, developing global collaboration and sharing genetic resources can enhance our resilience against potential crop diseases.

In conclusion, the potential for new crop diseases to cause substantial yield reductions is a real threat that warrants concern. Despite technological advancements, declining research investments could leave us unprepared for future emerging diseases. Continued emphasis on research, innovation, and international cooperation is necessary to safeguard global food security. Proactive measures now can help ensure that future generations are better protected against the devastating impacts of crop diseases.
