Answer: Sustainable Development is a transformative concept crucial for balancing human progress with planetary well-being. As extensively discussed in Unit 1 of BPAG-174, its core meaning was famously articulated by the Brundtland Commission in 1987. It defines sustainable development as "development that meets the needs of the present without compromising the ability of future generations to meet their own needs." This definition underscores two fundamental principles: intergenerational equity and in...

Answer: Sustainable Development (SD) aims to meet the needs of the present without compromising the ability of future generations to meet their own needs, balancing environmental protection, social equity, and economic viability. Education is recognized as a fundamental pillar for achieving this complex global objective, transcending mere knowledge dissemination to foster comprehensive societal transformation. Education for Sustainable Development (ESD) is a transformative learning approach that empowe...

Answer: Climate change refers to significant and long-term shifts in global or regional weather patterns, primarily driven by anthropogenic activities. The course emphasizes that this phenomenon is largely due to the increased concentration of greenhouse gases (GHGs) like carbon dioxide, methane, and nitrous oxide in the Earth's atmosphere, leading to an enhanced greenhouse effect and global warming. These emissions, stemming from industrialization, deforestation, and fossil fuel combustion, trap heat,...

Answer: Food security, as defined by the 1996 World Food Summit, means that "all people, at all times, have physical, social, and economic access to sufficient, safe, and nutritious food that meets their dietary needs and food preferences for an active and healthy life." This comprehensive definition moves beyond mere caloric intake, emphasizing the quality, safety, and cultural appropriateness of food. The concept of food security is fundamentally multi-dimensional, underpinned by four interconnected...

Answer: Green technologies play a pivotal role in enhancing food security by addressing environmental challenges and improving agricultural productivity sustainably. Food security, defined as access to sufficient, safe, and nutritious food for an active, healthy life, directly benefits from innovations that reduce resource dependency and environmental impact. Precision agriculture utilizes technologies like sensors, IoT, and AI to optimize resource use, such as water and fertilizers. This leads to high...

Answer: Sustainable Development is fundamentally characterized by **intergenerational equity**, which ensures that the needs of the present generation are met without compromising the ability of future generations to meet their own needs. Another key feature is the integration of three interdependent pillars: **economic development, social equity, and environmental protection**.

It aims to ensure the availability and sustainable management of water and sanitation for all people globally. This encompasses achieving universal and equitable access to safe and affordable drinking water. The goal also addresses access to adequate and equitable sanitation and hygiene for all, ending open defecation. Furthermore, it empha...

Answer: The 1992 Earth Summit (UNCED) in Rio de Janeiro yielded several pivotal outcomes, significantly advancing the sustainable development agenda. Key among these was the adoption of **Agenda 21**, a comprehensive, non-binding action plan for sustainable development to be implemented globally, nationally, and locally by organizations of the UN, governments, and major groups. The summit also produced the **Rio Declaration on Environment and Development**, articulating 27 principles for states to gui...

Answer: Green technology, or environmental technology, focuses on protecting the environment and conserving natural resources. Its key characteristics include minimizing pollution, enhancing resource efficiency (energy, water, materials), and utilizing renewable resources. It also emphasizes sustainable product lifecycles and the use of non-toxic materials. Categories of green technology are diverse. They encompass renewable energy sources like solar and wind power, effective waste management (e.g., re...

Answer: Environmental justice is paramount for achieving true sustainable development, as it addresses the fair treatment and meaningful involvement of all people, irrespective of race, colour, national origin, or income, with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies. It acknowledges that marginalized and vulnerable communities often bear a disproportionate share of environmental burdens, such as pollution and hazardous waste facilities...
