Inside Joel Tanui's Push to Turn Degraded Land into Climate Opportunity

The future of Kenya's climate resilience may not be decided first in a courtroom, a conference hall, or even at a global climate summit. It may instead be shaped on landscapes that many people have long written off as exhausted, barren, or beyond recovery. Across Kenya's arid and semi-arid lands, where failed rains, soil erosion, and shrinking vegetation have become familiar realities, a different conversation is beginning to take root. It is a conversation about restoration rather than retreat, productivity rather than abandonment, and opportunity rather than decline.

That shift helps explain why the State Department for Irrigation has expanded its focus beyond irrigation infrastructure. Increasingly, the department is treating land reclamation as a practical response to climate change, one that connects water management, food production, environmental restoration, and rural livelihoods. At the centre of this agenda is Mr. Joel K. Tanui, the Irrigation Secretary for Land Reclamation, Climate Resilience and Irrigation Water Management, whose docket reflects the growing recognition that restoring degraded landscapes is becoming a national development priority.

From Irrigation Projects to Landscape Restoration

For decades, irrigation discussions in Kenya largely revolved around canals, dams, pumps, and expanding cultivated acreage. Those investments remain essential, but climate change has exposed a wider challenge. Water infrastructure alone cannot deliver lasting agricultural productivity if the surrounding land continues to deteriorate through erosion, declining soil fertility, invasive species, and poor watershed management.

The State Department for Irrigation has increasingly framed irrigation as one element within a broader landscape approach. Its flagship Land Reclamation for Climate Resilience and Livelihood Enhancement Programme seeks to rehabilitate degraded land through water harvesting, irrigated pasture development, ecosystem restoration, and sustainable land management, particularly across Kenya's arid and semi-arid counties. Rather than viewing degraded land as a permanent liability, the programme treats it as an asset that can be restored to support agriculture, livestock production, and community resilience.

That institutional shift matters because nearly 80 percent of Kenya's landmass lies within ASAL regions. These areas are home to millions of people whose livelihoods depend directly on healthy ecosystems. Every restored watershed, rehabilitated grazing field, and reclaimed hectare strengthens both local livelihoods and national food security.

The Land Reclamation Bill Signals a New Direction

One of the clearest indications that land reclamation is moving from policy discussion to institutional action is the proposed Land Reclamation Bill, 2026. Mr. Tanui recently led the committee that presented the draft Bill to Cabinet Secretary Eng. Eric Mugaa, marking an important milestone in Kenya's efforts to establish a comprehensive legal framework for restoring degraded land.

The proposed legislation seeks to provide clear institutional responsibilities, financing mechanisms, and regulatory structures for land reclamation while promoting climate resilience, environmental restoration, food security, and sustainable water management. In many respects, it represents an acknowledgement that land degradation cannot be addressed through isolated projects alone. It requires a coherent national framework capable of coordinating government agencies, county governments, development partners, communities, and the private sector.

Legislation alone will not restore degraded landscapes. However, effective laws often provide the institutional certainty needed for long-term investment, accountability, and coordinated implementation. The proposed Bill therefore represents more than a legal reform. It reflects an evolving understanding that climate adaptation requires durable institutions as much as it requires engineering solutions.

Climate Change Is Redrawing the Development Agenda

Climate change has transformed the economics of land management. Prolonged droughts reduce agricultural output, increase livestock losses, accelerate rural poverty, and place greater pressure on water resources. These challenges eventually ripple through food markets, public finances, and household incomes.

Responding effectively requires moving beyond emergency relief toward long-term resilience. Land reclamation fits naturally within that transition because healthy soils store more water, restored vegetation reduces erosion, improved watersheds protect rivers and reservoirs, and productive grazing lands reduce pressure on fragile ecosystems.

Mr. Tanui's docket therefore sits at the intersection of several national priorities. Climate resilience is no longer viewed solely as an environmental objective. It has become a question of economic stability, agricultural productivity, and social wellbeing. Every hectare successfully reclaimed contributes to stronger food systems while reducing vulnerability to future climate shocks.

Why Irrigation Still Matters

Some observers may assume that a stronger emphasis on land reclamation diminishes the importance of irrigation. The opposite is true. Irrigation remains the practical mechanism that enables many restored landscapes to become productive again.

The State Department for Irrigation's broader investment strategy, including the National Irrigation Sector Investment Plan, continues to emphasize rehabilitation of public irrigation schemes, support for thousands of smallholder irrigation projects, expansion of irrigation in ASAL counties, and improved access to irrigation technologies. These investments complement land reclamation by ensuring that restored landscapes can sustain productive farming throughout increasingly unpredictable rainfall seasons.

This integrated approach reflects a simple but powerful idea. Water without healthy land cannot deliver sustainable productivity, while healthy land without reliable water remains vulnerable to recurring drought. Combining both creates greater resilience than pursuing either objective independently.

Turning Degraded Land into Economic Opportunity

Discussions about land degradation often focus on environmental losses. Equally important are the economic opportunities that successful restoration can unlock.

Reclaimed land can support irrigated agriculture, commercial pasture production, livestock fattening, agroforestry, and local enterprise development. Better-managed watersheds improve water availability for farming while reducing sedimentation that shortens the lifespan of reservoirs and irrigation infrastructure. Communities benefit from improved incomes, stronger food security, and greater resilience against climate-related shocks.

This broader perspective explains why the State Department for Irrigation increasingly describes land reclamation as both a climate intervention and a livelihood programme. Restoring degraded land is not simply about repairing environmental damage. It is about rebuilding productive economies in places where environmental decline has limited opportunity for generations.

Institutions Matter More Than Headlines

Large infrastructure projects often attract public attention because they produce visible results. Institutional reforms receive far less publicity despite their long-term importance.

Mr. Tanui's work illustrates this difference. Leading policy development, coordinating technical teams, advancing legislative proposals, and aligning climate resilience with irrigation planning may not generate dramatic headlines every week. Yet these are precisely the kinds of institutional processes that determine whether national programmes endure beyond individual political cycles.

Strong institutions establish continuity. They preserve technical knowledge, improve coordination across government agencies, attract investment, and provide confidence that climate programmes will continue delivering results over time. Kenya's experience increasingly demonstrates that successful climate adaptation depends as much on governance as it does on engineering.

The Road Ahead

Kenya's ambitions remain substantial, and implementation will present significant challenges. Land reclamation requires sustained financing, effective collaboration between national and county governments, strong community participation, reliable scientific data, and continuous monitoring of environmental outcomes. Restoring degraded landscapes is neither quick nor inexpensive.

Even so, the direction appears increasingly clear. Climate resilience is becoming embedded within agricultural policy, irrigation planning, and national development strategy rather than being treated as a separate environmental concern. That evolution reflects a deeper understanding that restoring ecosystems strengthens economies just as surely as it strengthens biodiversity.

Inside Joel Tanui's current docket lies a larger national story. Kenya is gradually redefining how it thinks about development in a warming world. Instead of accepting degraded land as an inevitable consequence of climate change, the State Department for Irrigation is advancing an alternative proposition: that restored landscapes can become engines of food security, economic opportunity, and long-term resilience. If that vision continues to gather institutional support, the country's most valuable climate asset may not simply be the water it stores, but the land it succeeds in bringing back to life.
