4 answers
Conditional Cash Transfer (CCT) programs have shown positive impacts on improving enrollment rates in the context of gender bias. Studies from South Asia, particularly India and Pakistan, highlight the success of CCT programs in promoting female school enrollment. These programs incentivize parents to delay marrying off their daughters and prioritize their education, leading to increased enrollment rates among girls. However, while CCT programs have been effective in boosting enrollment, there are mixed findings on their impact on learning outcomes, especially higher-order skills. Additionally, research suggests that CCT participation disproportionately limits migration for beneficiary women, emphasizing the gendered impact of these anti-poverty programs. Overall, CCT programs play a crucial role in addressing gender bias by encouraging female education and enrollment.Which are the most relevant and famous papers/handbooks about water governance and water law in California?

4 answers
The average loss of crops due to various factors like delayed harvesting, soil erosion, and pests ranges between 5% to 40% globally. Factors contributing to these losses include manual cutting operations, shatter loss, water erosion, and pests like weeds, pathogens, and animal pests. Mechanized harvest operations can help reduce losses, with well-trained combine operators achieving very low threshing, separating, and cleaning losses. In India, water erosion causes an estimated 16% loss in major cereal, oilseed, and pulse crops, with paddy being the most affected crop. Globally, potential losses due to pests vary from 50% in wheat to over 80% in cotton production, with actual losses ranging from 26% to 40% for different crops. Despite increased pesticide use, crop losses have not significantly decreased in the last 40 years, emphasizing the need for integrated pest/crop management strategies.What factors contribute to the longevity of individuals who participate in specific sports?
