Zimbabwe’s Drought Crisis: An In-depth Outline

Introduction

Zimbabwe, a landlocked country located in the southern part of Africa, boasts a diverse geography ranging from lush forests and highlands to vast savannas and semi-arid regions. The country’s unique topography includes the Zambezi and Limpopo rivers, which provide essential water resources for agriculture in this largely agrarian economy. Water, a vital element for life and economic development, plays an indispensable role in Zimbabwe’s agricultural sector, accounting for over 70% of its labor force.

Overview of Zimbabwe and its Geography

Spanning an area of approximately 390,757 square miles (1,011,568 square kilometers), Zimbabwe is home to a population of approximately 14.9 million people and shares its borders with South Africa, Botswana, Zambia, and Mozambique. The country’s diverse geography includes the Highveld plateau in the north, the Matabeleland plateau in the west, and the Lowveld region along the eastern borders with Mozambique and South Africa.

The Significance of Water for Agriculture in Zimbabwe

Approximately 70% of the labor force in Zimbabwe is engaged in agriculture, with Rain-fed subsistence farming being the primary means of livelihood for a significant portion of the population. The agricultural sector contributes around 15% to the country’s Gross Domestic Product (GDP). Water is essential for irrigating crops, maintaining livestock, and ensuring food security. The Zambezi and Limpopo rivers are the primary sources of water for agriculture in southern Africa, including Zimbabwe.

Causes of Zimbabwe’s Drought Crisis

Climate variability, human activities, and natural factors have contributed to Zimbabwe’s drought crisis. Prolonged periods of below-average rainfall, known as El Niño and La Niña events, have become more frequent in recent decades, leading to recurring droughts. Human activities, such as deforestation, unsustainable agricultural practices, and population growth, have exacerbated the impact of droughts on water resources and food production.

Impacts of Zimbabwe’s Drought Crisis

The drought crisis has had detrimental consequences on Zimbabwe’s economy, food security, and livelihoods. The agricultural sector has been hit hardest, resulting in reduced crop yields, increased food prices, and food shortages. Livestock farming has also been affected due to lack of water and pasture, leading to livestock deaths and reduced milk production. The crisis has further exacerbated poverty and malnutrition among the vulnerable population.

Mitigation Strategies for Zimbabwe’s Drought Crisis

The international community, development partners, and the government of Zimbabwe have implemented various mitigation strategies to address the drought crisis. These include emergency food assistance programs, water conservation initiatives, and sustainable agricultural practices such as irrigation systems and agroforestry. Additionally, efforts have been made to increase the country’s resilience to climate variability by investing in renewable energy sources, such as solar and wind power, and improving early warning systems for droughts.

Causes of the Drought Crisis in Zimbabwe

The drought crisis in Zimbabwe is a complex phenomenon with both natural climate factors and human-induced factors contributing to its severity.

Natural climate factors

El Niño Southern Oscillation (ENSO) and La Niña Southern Oscillation (LNSO), two climate phenomena, have played a significant role in the drought crisis in Zimbabwe. ENSO is characterized by the warming of sea surface temperatures in the tropical Pacific Ocean, which can lead to decreased rainfall in Eastern Africa including Zimbabwe. Conversely, La Niña, the cooling phase of ENSO, can also result in below-average rainfall in this region.

Seasonal climate patterns and weather variability

Beyond ENSO and LNSO, seasonal climate patterns and weather variability also contribute to the drought crisis in Zimbabwe. The country experiences two rainy seasons: the main season from November to March and the minor season from October to December. However, these patterns have become increasingly unpredictable leading to erratic rainfall.

Human-induced factors

Land degradation and deforestation, largely due to unsustainable farming practices, have exacerbated the drought crisis in Zimbabwe. Soil erosion, soil compaction, and nutrient depletion make it difficult for crops to thrive even during normal rainfall conditions.

Inefficient water management and misallocation

Another major human-induced factor is inefficient water management and misallocation. Zimbabwe’s water resources are not evenly distributed both spatially and temporally, and the existing infrastructure for water harvesting and distribution is inadequate. Agriculture, which is the main water consumer, often receives priority over domestic use and other sectors during droughts.

Climate change and its potential impact on drought frequency and severity

Climate change further complicates the situation. Rising temperatures can increase evaporation rates, reduce soil moisture and amplify rainfall variability, potentially making droughts more frequent and severe in Zimbabwe.

I Impacts of the Drought Crisis in Zimbabwe

Agricultural sector

Crop failures and food shortages: The drought crisis in Zimbabwe has resulted in massive crop failures, particularly for staple foods like maize, sorghum, and beans. This has led to severe food shortages, with some areas experiencing famine-like conditions.
Livestock losses: The drought has also caused extensive livestock losses due to lack of water and pasture, further exacerbating food insecurity.
Economic consequences, including inflation and currency devaluation: The agricultural sector’s collapse has had ripple effects on the Zimbabwean economy, leading to inflation and currency devaluation.

Water and sanitation sector

Reduced water availability for domestic use, agriculture, and industry: The drought has significantly reduced the availability of water for various uses, leading to water rationing in some areas.
Increased water contamination and potential health risks: With less water available, there is a higher risk of contamination due to the use of untreated or contaminated sources.

Health sector

Malnutrition and associated diseases, especially for vulnerable populations: The drought has led to widespread malnutrition, increasing the risk of related diseases such as marasmus, kwashiorkor, and anemia.
Increased prevalence of waterborne and other communicable diseases: The lack of clean water and sanitation facilities has led to a rise in the incidence of waterborne diseases like cholera, typhoid, and dysentery.

Social sector

Displacement, migration, and forced evictions due to food and water scarcity: Many people have been displaced from their homes due to drought-related conditions, leading to overcrowding in urban areas and the potential for social unrest.
Increased poverty levels and exacerbation of existing social inequalities: The drought crisis has pushed many Zimbabweans further into poverty, widening the gap between rich and poor.

E. Political and security implications
