Long Term Effects of Conflict on Water and Agriculture

/ General / By

Conflict is a harsh reality that affects societies on multiple fronts, but few impacts are as enduring and devastating as those on water resources and agriculture. Wars and prolonged disputes disrupt access to water and food production systems, leading to long-term environmental degradation, food insecurity, and public health crises. Understanding these effects is critical for policymakers, humanitarian organizations, and communities striving to rebuild and sustain livelihoods in war-affected regions.

Environmental degradation of water sources

Conflicts often directly or indirectly damage natural water sources such as rivers, lakes, and aquifers. Military activities—shelling, bombings, or chemical use—can pollute water bodies with toxic substances, heavy metals, and debris. For example, the use of explosives can release contaminants into groundwater, making it unsafe for human consumption and irrigation.

Additionally, armed groups may deliberately target water sources to control populations or deny resources to rivals, exacerbating scarcity. Pollution from destroyed infrastructure and lack of waste management during conflicts further degrades water quality. In some regions, the destruction of upstream watersheds through deforestation or land mines reduces natural water retention, leading to soil erosion and decreased water availability downstream long after hostilities end.

Ecosystems dependent on clean water also suffer. Wetlands dry out, fish populations decline, and natural filtration processes weaken, reducing biodiversity and ecosystem services that support agriculture and human settlements.

Impact on water infrastructure

Water supply systems are vulnerable targets during conflicts. Pipelines, wells, pumps, treatment plants, and irrigation channels may be damaged or destroyed, disrupting access to clean water. Repair and maintenance often become impossible amid ongoing violence or sanctions, allowing infrastructure to deteriorate further.

Damaged infrastructure leads to reduced water availability for both domestic uses and agricultural irrigation. Rural communities relying on traditional irrigation methods may find their fields dry, while urban populations face shortages affecting health and sanitation.

In addition, the conflict-driven collapse of governance often means no effective institutions remain to manage water resources, leading to misallocation and overuse of limited water supplies. Conflicts also hinder investment and technological upgrades, leaving water infrastructure outdated and inefficient well into the post-conflict era.

Soil degradation and loss of arable land

Agricultural land faces long-term degradation from conflict through multiple pathways. Bombing and shelling can physically destroy farmland or render it unsafe due to unexploded ordnance. Soil contamination by heavy metals or chemicals can limit crop growth for years.

Land abandonment occurs when rural populations are displaced, leaving fields untended and prone to erosion or invasions by invasive plant species. Without regular cropping and soil management, vital nutrients diminish, reducing soil fertility.

Additionally, water scarcity caused by damaged irrigation systems or upstream diversion during conflicts exacerbates soil degradation. Salinization may occur when irrigated soils are poorly managed, rendering land unsuitable for future use.

Loss of land tenure security due to displacement or destruction of records complicates restoration efforts, as farmers lose access or incentives to rehabilitate degraded fields. This loss of productive agricultural land directly undermines food production capacity.

Agricultural productivity decline and disruption

The combined effects of water contamination, soil degradation, and infrastructure destruction severely impact agricultural productivity during and after conflict. Crop yields often plummet due to poor growing conditions, lack of inputs such as seeds and fertilizers, and reduced labor availability when farmers are displaced or engaged in fighting.

Irrigation-dependent crops suffer especially from reduced water supply and deteriorated irrigation networks. Livestock production is also hit by loss of grazing land, water scarcity, and death or theft during conflicts.

Supply chain disruptions—like blocked roads or destroyed marketplaces—further constrain farmers’ ability to sell produce or acquire necessary farming inputs. Seed varieties and farming knowledge may be lost as communities disperse, leading to less diverse and less resilient agricultural systems.

Long-term productivity declines often continue even after hostilities end, as rebuilding agricultural systems requires time, investment, and stability.

Legacy effects on food security and livelihoods

The long-term consequences of conflict on water and agriculture resonate deeply through food security and livelihoods. Declined agricultural output leads to chronic food shortages and higher prices, worsening malnutrition and hunger.

Reduced access to clean water increases waterborne illnesses, compromising community health and labor productivity, which in turn affects agricultural recovery.

Displaced populations may depend heavily on humanitarian aid, creating cycles of dependency that hinder return to farming livelihoods. Women and marginalized groups often face disproportionate hardships in post-conflict settings, with limited access to resources for rebuilding lives.

Food insecurity also increases vulnerability to future conflicts by aggravating social tensions. The destruction of traditional agricultural practices disrupts cultural identity and community cohesion, further complicating recovery.

Socioeconomic consequences linked to water and agriculture

Water and agriculture form the backbone of many rural economies. Prolonged conflict undermines these sectors, triggering ripple effects on employment, income generation, and local economies.

Farm laborers lose jobs; smallholder farmers lose assets or land. Reduced agricultural exports can diminish national revenues. The loss of reliable water supplies affects industries and services reliant on water, compounding economic hardships.

Increasing poverty drives urban migration, adding pressure to already strained cities and services. Conflict-affected regions often experience a decline in education and health services, limiting human capital development critical for agricultural innovation and sustainability.

Reconstruction of water and agriculture sectors is therefore not only vital for food and water security but also for broader socioeconomic stability and recovery.

Climate change interactions with conflict impact

Climate change amplifies the adverse effects of conflict on water and agriculture. Changing rainfall patterns, prolonged droughts, and extreme weather events strain already fragile water systems and crop production.

Conflict zones often face degraded natural buffers like forests or wetlands that otherwise mitigate climate impacts. This double burden makes adaptation more difficult, deepening vulnerability to water scarcity and food insecurity.

Furthermore, competition over diminishing water and land resources due to climate stress can intensify conflicts, creating a feedback loop of environmental degradation and social instability.

Addressing these intertwined challenges requires integrated peacebuilding and climate adaptation approaches.

Strategies for recovery and resilience

Reversing the long-term effects of conflict on water and agriculture demands coordinated strategies emphasizing physical rehabilitation, institutional rebuilding, and community empowerment.

Key approaches include:

  • Repairing and upgrading water infrastructure such as pipelines, wells, and irrigation systems.
  • Remediating contaminated soils and water sources using safe, sustainable methods.
  • Restoring secure land tenure and access rights to encourage farmers to invest in land rehabilitation.
  • Providing agricultural inputs, training, and support to revive local food production and diversify crops.
  • Strengthening water governance institutions to ensure equitable and sustainable resource management.
  • Incorporating climate resilience into recovery plans to withstand future environmental stresses.
  • Prioritizing inclusive participation of affected communities, especially marginalized groups, in rebuilding efforts.

Long-term peace and development go hand in hand with restoring the integrity of water and agricultural systems. Only by addressing these core environmental challenges can war-torn societies rebuild sustainable livelihoods and secure their future.
