Environmental Threat & Security of Bangladesh

Linkage Between Environmental Issues and National Security

Security studies, once dominated by military affairs, now recognises the environment as a strategic variable.
• Security in IR is an “essentially contested” concept: its meaning shifts with historical context and scholarly debate.
• Traditional view: the State monopolises legitimate force; threats are violent (invasion, insurgency).
• Post-Cold-War view: non-state sources—economic crises, pandemics, climate disruption—create equally potent dangers.
• Environmental degradation blurs the line between internal and external threats: storms, sea-level rise, and resource scarcity can originate abroad (global emissions) yet devastate domestic stability.

Comprehensive National Security (CNS) for Bangladesh

CNS fuses two once-separate agendas:

1. Traditional national security (sovereignty, territorial defence).

2. Human security (safety of individuals from hunger, disease, disaster).
   The holistic lens keeps policy‐makers from treating floods, famines or epidemics as merely “development” issues; they are integral to state survival.

Principal Environmental Threats to Bangladesh’s Security

Threat to Territorial Integrity

• Global mean surface temperature has already risen $0.74^{\circ}C$ (1906-2005). The warming rate for the last 50 years is roughly double the 100-year average.
• Projected warming: $0.2^{\circ}C$ per decade over the next two decades.
• Sea-level projections: even a conservative $40\,\text{cm}$ rise by 2100; a $1\,\text{m}$ rise could erase the Sundarbans and turn $\approx 1000\,\text{km}^2$ of cropland and aquaculture into salt marsh.
• Knock-on effects: stronger cyclones, tornados, storm surges, loss of ecological equilibrium—potentially existential for a low‐lying deltaic nation.

Food Security

• Annual flood losses: $\approx 0.5\,\text{Mt}$ of rice (≈30 % of yearly grain imports).
• Temperature elasticity: a $4^{\circ}C$ rise could slash rice by 28 % and wheat by 68 %.
• IPCC (2007) forecasts by 2050: rice ↓8 %, wheat ↓32 %.
• Shorter winters ⇢ lower yields of potatoes and other rabi crops.
• Salinity intrusion and altered tides threaten inland fisheries—vital protein source.
• Population doubled (1971-2021) to $160\,\text{million}$; food demand outpaces environmentally constrained supply, amplifying security risk.

Demographic Pressures & Migration

• Poverty snapshot: 40 % of citizens (≈60 million) below the poverty line; 25 % extremely poor; 10 % often survive on ≤2 meals/day.
• Environmental stressors (erosion, drought) undermine livelihoods, thwarting poverty-reduction programmes.
• Rural push factors + urban pull ⇒ mass internal migration; environmentally dispossessed become “climate refugees.”
• One-metre sea-level rise could inundate $22{,}889\,\text{km}^2$ (≈15.8 % of national territory), intensifying displacement.

Health Security

• Environment-linked diarrhoea and malnutrition already dominate morbidity patterns; risk projected to peak circa 2030.
• Chronic liver disease victims: $\approx 350\,\text{million}$ worldwide, with Bangladesh heavily burdened; one-third of rural residents encounter Hepatitis B in their lifetime.
• Industrial effluents bio-accumulate through plants, fish, meat ⇒ systemic toxicity.
• Economic feedback loop: disease lowers productivity, widens supply-demand gaps, triggers price spikes, unemployment, slum expansion and social conflict.

Political Security

• A government’s legitimacy relies on economic strength, healthy demographics and sound resource management.
• Environmental degradation saps GDP, stirs discontent, strains institutions—conditions ripe for political instability.

Policy Measures & Mitigation Strategies

Population Control

• Over-population is a structural driver of environmental stress.
• Lower fertility grants fiscal space for environmental investment.
• Tactics: public-awareness campaigns, reproductive-health services, enforcement of conservation laws.

Land-Use Policy

• Reforms should:
– Safeguard prime farmland from urban sprawl or industrial encroachment.
– Defend erosion-prone coastal belts; promote reclamation projects.

Forest Protection & Forestation

• Energy substitution (solar, gas, wind, hydro) decreases fuel-wood demand.
• Nationwide plantation drives plus strict bans on logging in catchments, steep slopes, wildlife reserves.
• Halt conversion of forest land; assign stewardship to vetted private or community entities.

Fresh-Water Management (Multi-Directional Approach)

• Mandatory effluent-treatment plants; regulate agro-chemicals; smart waste disposal.
• BWDB roles: silt management, salinity barriers, watershed planning, land reclamation.
• Rainwater harvesting for drought-season buffering.

Environmental Diplomacy

• Regional fora (e.g., SAARC) can coordinate basin-wide research, training, monitoring.
• Multilateral partnerships with UN agencies (UNEP, UNDP, FAO) facilitate funding, technology transfer, Himalayan forestation, and resilience projects.
• Aim: embed environmental stewardship within security dialogue, turning shared risks into cooperative ventures.

Integrative Perspective & Ethical Imperatives

1. Interdependence: Bangladesh’s fate is tied to global emission trajectories; therefore equity in climate negotiations is a justice issue.

2. Human-rights lens: protecting citizens from drought or cholera is as vital as shielding them from invasion.

3. Prevention > Response: every $\$1$ in adaptation today can avert multiples in future disaster relief and conflict mediation costs.

By reframing environmental degradation as a core element of comprehensive national security, Bangladesh can prioritise cross-sectoral policies that safeguard territory, nourish its people, stabilise politics and uphold the dignity of present and future generations.
