 Abstract

The rapid pace of industrialization, urbanization, and agricultural intensification has led to the generation of massive quantities of wastewater containing a complex mixture of organic matter, nutrients (nitrogen and phosphorus), pathogens, heavy metals, and synthetic chemicals. Discharge of untreated or poorly treated wastewater into natural water bodies contributes significantly to environmental pollution, eutrophication, oxygen depletion, and the spread of waterborne diseases. These issues not only threaten aquatic ecosystems but also impact human health and socio-economic development, especially in regions with inadequate wastewater infrastructure.

 Abstract

Climate change and desertification are pressing global challenges with profound implications for ecosystems and human societies. This paper reviews the human and natural drivers of climate change, summarizes recent direct observations and future projections, explores the connections between climate change and desertification, and details the actions taken by the World Meteorological Organization (WMO) to address these issues through observation, prediction, early warning, risk management, and international cooperation. Climate variability and extreme weather events continue to intensify, threatening food security, water resources, and sustainable development in vulnerable regions. Understanding the interactions between land degradation and climate dynamics is essential for designing effective adaptation and mitigation strategies. Improved monitoring and early warning systems can help communities build resilience and reduce the impacts of droughts and floods. International collaboration and capacity building are critical to managing transboundary climate risks and promoting sustainable land management.

 Abstract

The Convention on Biological Diversity 1992 defines biodiversity as 'the variability among living organisms from all sources including terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part which includes diversity within species, between species and of ecosystems' Biodiversity is the living foundation for sustainable development. The totality of genes, species and ecosystems of a region is also called biodiversity. In an ecosystem the community of living organisms live in conjunction with the non-living components of their environment interacting as a system. They live in harmony with one another. This leads to a healthy growth of a community and thus ecological balance is maintained.

 Abstract

Habitat fragmentation stands as a critical factor contributing to the ongoing decline in biodiversity, particularly in ecologically fragile zones such as Andhra Pradesh, India. This study investigates the scope and ecological impact of fragmented habitats across diverse landscapes within the state. Through the integration of satellite-based remote sensing, GIS tools, and direct field assessments, the research measures habitat deterioration, diminishing patch sizes, and the disruption of ecological corridors over a 25-year span. Indicators like species richness, population abundance, and habitat continuity are analyzed within forested, coastal, and agrarian ecosystems. The findings reveal a pronounced reduction in native biodiversity, especially within the Eastern Ghats and wetland areas of the Krishna-Godavari delta. Key drivers include urbanization, infrastructural development, and deforestation. The study underscores the urgency for holistic land-use strategies, ecological restoration, and participatory conservation initiatives. The insights offered are intended to guide regional policy formulation and contribute to global biodiversity and climate resilience objectives outlined in the Sustainable Development Goals.

 Abstract

Vijayawada, a fast-growing city at the Krishna River, has witnessed rising flood frequency and intensity over the past decades. This study explores the ecological role of wetlands in mitigating flood impacts, with specific emphasis on the modified wetland processes of the region. Wetlands like Kolleru and surrounding marshlands traditionally acted as hydrological buffers, controlling water levels and soaking up surplus rain [1]. The destruction and encroachment of these wetlands have severely impaired their ability to contain floodwaters [3]. This study, based on an examination of wetland biology--focusing on aquatic vegetation, benthic microbes, and faunal interactions--identifies the biological processes which facilitate flood resilience. The results emphasize the importance of incorporating wetland conservation and restoration into urban flood management plans. The study promotes a nature-based strategy that integrates wetland ecosystem services into the urban planning of Vijayawada in a bid to improve climate resilience and ecological sustainability [4,5].

 Abstract

Climate change and environmental pollution are among the most pressing global challenges of the 21st century. The intensifying and unpredictable disruptions in weather patterns poses a severe threat to global biodiversity and the goals of sustainable development. shifting climate patterns, and increasing pollution levels are causing habitat loss, species extinction, and disruption of vital ecosystem services. Rising temperatures, erratic rainfall, severe droughts, floods, and extreme weather events are pushing many species beyond their capacity to adapt. Habitats are shrinking or shifting, leading to species extinction and loss of genetic diversity. These impacts directly affect food and water security, human health, economic stability, and efforts to achieve global sustainable development goals (SDGs). Coral reefs are bleaching due to warming seas, forests are facing increased wildfires and pest outbreaks, wetlands are drying up or flooding unpredictably, disrupting breeding grounds for many birds and aquatic species. Such ecological imbalances also threaten food security, clean water supply, and the livelihoods of millions, especially indigenous and rural communities who depend directly on natural resources. Sustainable development, which aims to balance economic growth, social well-being, and environmental protection, is undermined by biodiversity loss. When ecosystems degrade, they provide fewer services like carbon sequestration, soil fertility, pollination, and climate regulation all of which are critical to human well-being and climate resilience. Addressing these challenges requires integrated strategies, including reducing greenhouse gas emissions, transitioning to renewable energy, enforcing pollution control measures, conserving and restoring ecosystems, and promoting sustainable resource use. Community participation, environmental education, and international cooperation are essential to ensure effective action. Protecting biodiversity and minimizing pollution are fundamental to building resilient ecosystems and societies capable of withstanding future environmental and socio-economic pressures. Climate change and environmental pollution are deeply interconnected and require urgent, coordinated action. Protecting biodiversity and combating climate change and pollution are crucial for a healthy planet and human well-being. Effective solutions need global cooperation, strong policies, community involvement, and sustainable lifestyles.

The Sustainable Development Goals (SDGs) are a set of 17 global objectives adopted by the United Nations in 2015 to achieve a sustainable and equitable world by 2030. These goals aim to end poverty, protect the planet, and ensure peace and prosperity for all people. The SDGs are interconnected, recognizing that economic, social, and environmental aspects are linked and essential for achieving sustainable development.The 17 SDGs include goals such as ensuring quality education, promoting sustainable economic growth, and protecting the environment. Some specific targets include ending hunger, achieving food security, and promoting sustainable agriculture. Other goals focus on providing clean water and sanitation, affordable and clean energy, and decent work and economic growth. The SDGs also emphasize the importance of reducing inequalities, promoting sustainable cities and communities, and taking action to combat climate change. Implementing the SDGs requires a collaborative effort from governments, businesses, and individuals. This can involve promoting sustainable practices, investing in renewable energy, and supporting initiatives that contribute to achieving the SDGs. For instance, artists are using their talents to raise awareness about the SDGs, such as creating abstract paintings that represent each goal. Such initiatives not only promote awareness but also inspire others to contribute to achieving the SDGs.The SDGs are crucial for creating a more equitable and sustainable world. By addressing these goals, we can ensure that all people enjoy peace and prosperity, now and in the future. This involves working together to protect the planet, end poverty, and promote sustainable development.

 Abstract

Basal stem rot (Ganoderma wilt) disease caused by Ganoderma spp is the most destructive disease of coconut. Described detailed basal stem rot (BSR) disease symptoms on coconut palm. BSR pathogens Ganoderma applanatum (Pers) Pat and G.lucidum (Leys.) Karst was isolated from brackets and tissues of root and stem of coconut. Different management practices including cultural methods, chemical control and also biological control of the basal stem rot disease induced by Ganoderma spp, were reviewed in this chapter. Detailed investigations in the biological control of this disease were carried out. In vitro studies revealed that the native biocontrol agents viz., Trichoderma viride, T.harzianum and T.hamatum were very effective in checking the radial growth of both the Ganoderma spp as well as in the production specific volatile and non-volatile metabolites that are antagonistic to the basal stem rot disease pathogens. All the three Trichoderma spp, were found to check the basal stem rot disease of coconut at field level effectively when applied at the rate of 50 gms of talc powder formulation in conjunction with 5 kg neem cake per palm/year. Based on the results, an integrated disease management with biological control as key component was formulated to combat the disease at field level. The formulated IDM strategy against BSR of coconut include application of 50g of talc powder formulation of T.viride along with 5 kg neem cake /tree/ annum for a continuous period of over three years besides other cultural practices.
