What are the advantages of traditional methods of farming?4 answersTraditional methods of farming offer numerous advantages such as improved soil fertility, carbon sequestration, resource utilization, biodiversity maintenance, sustainability, and environmental protection. These methods have been developed over centuries based on indigenous knowledge and experience, ensuring ecological sustainability and maintaining biodiversity. Practices like agroforestry, intercropping, crop rotation, and cover cropping contribute to enhanced soil health and crop productivity while reducing the negative impacts of modern agricultural practices like water pollution and soil contamination. Additionally, traditional farming systems in India have proven to be sustainable by preserving fertility and biodiversity over generations, emphasizing the importance of utilizing ancestral knowledge for future agricultural sustainability.
What are some of the key differences between modern and traditional techniques in animal husbandry?5 answersKey differences between modern and traditional techniques in animal husbandry include investment trends, returns, and health parameters. Modern dairy farming shows higher net returns per liter of milk produced compared to traditional methods. Additionally, animals in modern farms exhibit lower respiration and heart frequencies, along with better blood parameters like WBC, RBC, and cortisol levels, in contrast to those in traditional setups. Traditional farming is characterized by techniques like seed selection, machinery usage, and reliance on government policies, while modern practices involve genetic modifications, biofertilizers, and organic farming approaches. Understanding these differences is crucial for optimizing farm management, enhancing animal welfare, and improving overall production efficiency in animal husbandry systems.

How traditional methods in agriculture have evolved.?5 answersTraditional methods in agriculture have evolved over time to incorporate new technologies and scientific advancements. Initially, farmers relied on natural biological evolution and careful selection of plant varieties for genetic improvement. However, traditional landraces of crops have also undergone changes over time due to natural selection, climate, and farmers' own selection processes. Traditional farming practices, based on indigenous knowledge, have been used for centuries and include techniques such as agroforestry, crop rotation, and integrated crop-animal farming. In the mid-20th century, investments in knowledge, education, and improved inputs were seen as crucial for transforming agriculture. Traditional agriculture has also adapted to local ecology, with early examples of soil fertility management and the use of legume crops for sustainable farming. These changes and adaptations have helped agriculture to meet the increasing demands for food production while considering environmental sustainability and resource utilization.
What are the challenges of traditional farming?3 answersTraditional farming faces several challenges. These challenges include maintaining farm productivity, meeting community expectations, living with less water, evaluating new opportunities, natural resource declines, climate change risk, women disempowerment, conflict, and urbanization. Additionally, traditional farming practices often maximize production without considering the impacts on the environment and society. Transitioning from conventional to organic farming also presents obstacles such as complete deterrence from chemical inputs, significant changes at the farm level, and changes in farmer attitudes. Furthermore, public policies in some countries promote large-scale monoculture production and limit farmer choices, contributing to environmental challenges. These challenges are complex and dynamic, requiring a multipronged approach involving individual farmer actions, research, education, and policies that promote sustainability.
