Food resources: World food problems, changes caused by agriculture and overgrazing, effects of modern agriculture, fertilizer-pesticide problems, water logging, salinity, case studies (खाद्य संसाधन: विश्व खाद्य समस्याएँ, कृषि और अत्यधिक चराई से होने वाले परिवर्तन, आधुनिक कृषि के प्रभाव, उर्वरक-कीटनाशक समस्याएँ, जलभराव, लवणता, केस अध्ययन):-

World Food Problems (विश्व खाद्य समस्याएँ):-

i. Global Hunger and Food Security (वैश्विक भूख और खाद्य सुरक्षा):- Despite advances in agriculture, hunger persists globally. Over 820 million people worldwide suffer from chronic hunger, largely due to poverty, conflict, climate change, and economic instability.

(कृषि में प्रगति के बावजूद, वैश्विक स्तर पर भूख की समस्या बनी हुई है। विश्वभर में 820 मिलियन से अधिक लोग भूख से पीड़ित हैं, जो मुख्य रूप से गरीबी, संघर्ष, जलवायु परिवर्तन और आर्थिक अस्थिरता के कारण होती है।)

ii. Food Distribution Inequality (खाद्य वितरण में असमानता):- There is a significant imbalance in food distribution. While some regions suffer from food scarcity, others waste large quantities of food. The disparity between food-rich and food-poor regions exacerbates global food insecurity.

(खाद्य वितरण में महत्वपूर्ण असमानता है। जबकि कुछ क्षेत्रों में खाद्य की कमी है, अन्य क्षेत्रों में बड़ी मात्रा में भोजन बर्बाद हो जाता है। खाद्य समृद्ध और खाद्य गरीब क्षेत्रों के बीच असमानता वैश्विक खाद्य असुरक्षा को बढ़ावा देती है।)

iii. Population Growth (जनसंख्या वृद्धि):- The global population is expected to reach 9.7 billion by 2050, putting increased pressure on food resources. Meeting the food demand of a growing population while ensuring sustainability is a major challenge.

(वैश्विक जनसंख्या 2050 तक 9.7 अरब तक पहुंचने की उम्मीद है, जिससे खाद्य संसाधनों पर दबाव बढ़ेगा। बढ़ती जनसंख्या की खाद्य मांग को पूरा करना और साथ ही स्थिरता सुनिश्चित करना एक बड़ा चुनौतीपूर्ण कार्य है।)

iv. Climate Change (जलवायु परिवर्तन):-
