Book Review: Design with Nature by Ian McHarg
Ian L. McHarg’s “Design with Nature,” released in 1969, is an important work in landscape architecture and environmental planning that continues to have an impact on urban planning, ecology, and environmental science. McHarg’s method incorporates natural systems into design, focusing on ecological planning that balances human activity and environmental sustainability. His “layer-cake” methodology combines natural and human-made components to create a holistic picture of the landscape, allowing planners to select appropriate locations for development, conservation, and restoration. McHarg’s methodology, which incorporates the novel use of transparent overlays to map geology, hydrology, vegetation, and land use, transformed planning processes. This approach has grown with current Geographic Information Systems (GIS), broadening its applicability and precision. McHarg’s principles have been implemented into landscape architecture curricula and professional practices all around the world, influencing important projects and promoting sustainable and landscape urbanism. Despite some criticism of his deterministic approach and resource-intensive procedures, McHarg’s work has remained very influential. In light of climate change and environmental challenges, his emphasis on incorporating natural systems into planning is more important than ever. McHarg’s theories have influenced modern approaches such as green infrastructure, climate resilience planning, and ecosystem-based adaptation.

Taking the step forward overcoming the plight
- McHarg addresses environmental crises caused by industrialization and modern development, highlighting degradation of landscapes, loss of biodiversity, and pollution.
- He criticizes conventional planning for prioritizing economic growth over environmental sustainability. McHarg advocates for ecological planning principles and interdisciplinary approaches, emphasizing the importance of understanding natural systems.
- He emphasizes the need for education and public awareness to drive change and promote sustainable behaviors. The book calls for a vision of resilience and sustainability, where human development coexists with thriving ecosystems.
- McHarg advocates to take a step forward for sustainable development through ecological planning principles. He advocates for a holistic, interdisciplinary approach, integrating ecological knowledge into planning and design.
- Tools like land suitability analysis guide decisions about land use, infrastructure, and resource management. McHarg highlights successful examples of ecological planning in practice, demonstrating benefits like improved environmental quality and reduced vulnerability to natural hazards. He calls for a paradigm shift in development, urging collaboration across disciplines to address environmental challenges.
Balancing ecology and urbanization
Caste, Capsule, Nature and Values
- The author explores the relationship between human environments and ecological principles. The book critiques the compartmentalization of society, comparing it to a caste system, and advocates for a holistic approach to urban planning that aligns with natural processes.
- McHarg emphasizes the importance of incorporating natural elements into urban planning, such as green spaces and water bodies, to enhance ecological balance and improve urban life. He also delves into the philosophical and ethical foundations of McHarg’s ecological planning approach, emphasizing ecological sustainability and the importance of respecting natural processes and biodiversity.
- “A Response to Values” proposes practical strategies for implementing these values in planning and development practices, emphasizing the importance of interdisciplinary collaboration and the integration of ecological knowledge into policy-making and design.
- The book presents a cohesive argument for a paradigm shift in urban development and environmental stewardship, advocating for a comprehensive, value-driven approach that respects and integrates natural systems.
Ecological Planning in this capsule world
- The author emphasizes the importance of integrating ecological principles into planning and development to achieve sustainable human-environment interactions.
- He argues that Earth operates as a closed system with finite and interconnected resources, and that human activities must respect this by recognizing the limits of resource exploitation and the need for sustainable practices. McHarg critiques current development paradigms that often ignore ecological constraints, leading to environmental degradation and unsustainable growth.
- He advocates for a shift from linear to circular economic models that mimic natural systems. He signifies “The Process as Values,” McHarg advocates for a value system that prioritizes ecological health, sustainability, and the intrinsic worth of all living beings.
- He discusses practical approaches to embedding these values into planning processes, including interdisciplinary collaboration, participatory decision-making, and long-term ecological thinking.
