Living in harmony with nature has emerged as a transformative paradigm critical for modern development, particularly when examined through the lens of dryland regions. These areas, covering about 40% of the Earth’s terrestrial surface, are among the most vulnerable ecosystems. Yet, they harbor remarkable biodiversity that plays an indispensable role not just ecologically, but socioeconomically. The International Day for Biological Diversity 2025, themed “Harmony with Nature and Sustainable Development,” directs much-needed attention to this intricate relationship, urging integrated approaches that honor ecological limits while advancing human progress.
Drylands are defined by extreme water scarcity, harsh climates, and nutrient-poor soils, making them fragile ecological zones where conventional development models simply do not fit. Here, biodiversity transcends abstract notions—it is a foundation of resilience, livelihoods, and food security. Effectively, development and biodiversity conservation cannot be treated as opposing forces but must be mutually supportive to ensure sustainability.
The biological diversity in drylands includes an impressive array of flora and fauna uniquely adapted to survive in arid environments. This heritage has evolved over millennia, weaving a complex web of ecological and evolutionary processes. Native plant species and soil microorganisms, for instance, perform vital ecosystem functions such as nutrient cycling, carbon sequestration, and soil stabilization. These natural functions underpin agriculture and pastoral livelihoods, which remain dominant in dryland communities worldwide. If these ecosystems falter, so do the economies and food supplies dependent upon them.
Indigenous knowledge systems also represent a crucial dimension of dryland biodiversity. Local communities have cultivated sophisticated techniques for managing scarce water and soil resources, demonstrating a deep-rooted harmony with nature. To disregard this traditional wisdom would be to risk undermining both ecological integrity and socioeconomic resilience. The power of merging indigenous approaches with modern scientific advancements is evident in areas like genomics, where breakthroughs such as the multi-assembly goat pangenome illuminate how genetic diversity can enhance adaptive traits in livestock. Since goats are commonly reared in drylands for their ability to thrive on sparse vegetation, genetics-driven resilience offers direct benefits to food security and poverty reduction.
However, despite their immense importance, drylands face mounting threats from unsustainable development and climate change. Drought frequency has spiked since 2000, as highlighted by the United Nations Convention to Combat Desertification (UNCCD), intensifying pressures on both natural ecosystems and human populations. Land degradation and desertification exacerbate the vulnerability of these fragile areas, while poorly planned agricultural or infrastructural projects often cause habitat loss and biodiversity decline. Fragmented dryland corridors, such as the Sahyadri-Konkan Corridor, become battlegrounds for the consequences of shortsighted development that ignores ecological constraints.
At the heart of the issue lies a policy disconnect: biodiversity goals are frequently sidelined in favor of rapid economic growth, leading to undervaluation of the ecosystem services drylands provide. This mismatch hampers progress toward Sustainable Development Goals (SDGs) that seek to improve ecosystem health, alleviate poverty, and foster climate adaptation simultaneously. Without reconciling these objectives, dryland development is bound to entrench ecological degradation and social inequities.
Amid these challenges, nature-based and community-centered solutions offer promising pathways forward. Such approaches leverage local knowledge and ecological principles to bolster ecosystem resilience while enhancing human well-being. Implementing soil and water conservation techniques, agroforestry, and restoration of native vegetation can rehabilitate degraded lands and sustain agricultural productivity in drylands. Collaborative efforts between research institutions and local stakeholders, like partnerships involving NIRDPR and ICRISAT, focus on promoting climate-smart farming and drought-tolerant crops. By empowering farmer households and cooperatives, these initiatives support inclusive green agriculture that is rooted in sustainability from the grassroots level up.
Additionally, international frameworks like the FAO’s Global Framework on Water Scarcity and Agriculture (WASAG) advocate integrated water management and agricultural strategies specifically tailored for dryland contexts. This global coordination aligns with the UN’s vision of “living in harmony with nature,” emphasizing the dual need for environmental stewardship and equitable human development. The synergy between cutting-edge science and indigenous wisdom is key to devising culturally resonant, ecologically sound responses that can convert drylands from vulnerable zones into exemplars of sustainable coexistence.
Ultimately, development divorced from biodiversity conservation leads nowhere. For drylands, ecological, social, and economic fabrics are inextricably linked with biodiversity and ecosystem function. The International Day for Biological Diversity 2025’s theme rings true: sustainability is not about choosing nature or progress but weaving them together into a coherent whole that honors natural limits while advancing human well-being. Achieving this balance demands a realignment of policy, science, and societal values to recognize life’s interconnectedness.
With threats like climate change and desertification intensifying, unlocking drylands’ potential through nature-based, community-rooted approaches provides a hopeful roadmap. Living in harmony with nature across these fragile landscapes is not a luxury—it’s an imperative for the survival and prosperity of present and future generations. By embracing biodiversity as a source of resilience and opportunity, drylands can transform from precarious frontiers into sustainable beacons of development.
