Analysis of Sustainable Development Goals in the Article

1. Which SDGs are addressed or connected to the issues highlighted in the article?

• SDG 2: Zero Hunger

  The article directly addresses SDG 2 by focusing on improving the resilience and yield of sorghum, which is described as a “staple crop in many parts of the world, especially in sub-Saharan Africa.” The research aims to enhance “food security” and “food availability” by identifying drought-tolerant varieties that can maintain production even under water stress, thus contributing to ending hunger.

• SDG 6: Clean Water and Sanitation

  The core theme of the article is managing “scheduled water stress” and “water scarcity.” The research on sorghum varieties that can thrive with less water directly connects to sustainable water management. The article highlights how these resilient crops can “reduce dependency on irrigation,” which is crucial for conserving water resources in “drought-prone regions.”

• SDG 13: Climate Action

  The article is framed within the context of adapting agriculture to “climate change.” It discusses developing “crop resilience in the face of climate change” and mitigating the “adverse effects of drought” caused by rising global temperatures. The study’s findings are presented as a solution to help farmers “adapt to the changing climate,” thereby strengthening resilience to climate-related hazards.

• SDG 15: Life on Land

  The research promotes “sustainable agriculture practices” that can “lessen the ecological footprint of farming.” By cultivating crops that are better suited to arid environments and require less water, the agricultural system becomes more sustainable. This helps in managing land resources effectively and combating the effects of drought, which is relevant to protecting terrestrial ecosystems.

2. What specific targets under those SDGs can be identified based on the article’s content?

• SDG 2: Zero Hunger

  • Target 2.4: By 2030, ensure sustainable food production systems and implement resilient agricultural practices that increase productivity and production, that help maintain ecosystems, that strengthen capacity for adaptation to climate change, extreme weather, drought, flooding and other disasters and that progressively improve land and soil quality. The article’s focus on developing “resilient” sorghum varieties that can “withstand the impacts of climate change” and drought directly supports this target.
  • Target 2.5: By 2020, maintain the genetic diversity of seeds, cultivated plants and farmed and domesticated animals and their related wild species… The research involves a “meticulous selection process of the sorghum varieties studied” and emphasizes the need for “ongoing studies in the realm of crop genetics and breeding,” which aligns with maintaining and utilizing crop diversity.

• SDG 6: Clean Water and Sanitation

  • Target 6.4: By 2030, substantially increase water-use efficiency across all sectors and ensure sustainable withdrawals and supply of freshwater to address water scarcity… The identification of sorghum varieties that have “reduced water dependency” and can maintain yields under “scheduled water stress” is a direct contribution to increasing water-use efficiency in the agricultural sector.

• SDG 13: Climate Action

  • Target 13.1: Strengthen resilience and adaptive capacity to climate-related hazards and natural disasters in all countries. The entire study is an exercise in strengthening agriculture’s adaptive capacity. The “identification of specific sorghum varieties that exhibit remarkable resilience under water-stressed conditions” is a tangible strategy to build resilience against climate-induced droughts.
