The recent military coup in Niger amplifies these concerns.
The coup’s aftermath holds potential for domestic unrest, regional instability, increased militant activities, democratic regression, and a power vacuum, fostering uncertainty and eroding trust in new leadership.
Post-coup, societal polarization and clashes between coup proponents and opponents could ignite protests, demonstrations, and potential violence, exacerbating existing social and ethnic tensions.
These multifaceted factors collectively impact the human experience in Niger, constraining basic access, education, healthcare, and economic growth opportunities.


Guinea is one of the poorest countries in the world, with a per capita GDP of only $1,210 (PPP) and the average person living on less than $2 per day. The country has a long history of political instability, economic hardship, corruption, and conflict which have disrupted infrastructure and discouraged investment. Despite having natural resources, wealth has mainly enriched a small elite while most remain poor.
Being landlocked with a hot climate also makes it difficult to farm and raise livestock, the primary income sources for many. These factors have significantly impacted living standards – Guinea has high illiteracy, low life expectancy, and malnutrition is widespread with limited healthcare access. Children are often malnourished and lack quality education, impairing cognitive development and lowering IQ scores on average.

Burkina Faso

Burkina Faso is a low-income, Sahelian country with limited natural resources. Its economy relies heavily on agriculture, which employs 80% of the population but is vulnerable to climate change and drought. Over 40% live below the poverty line, impacting access to basic needs.
Burkina Faso ranks low in HDI, reflecting challenges including a lack of natural resources constraining growth; high unemployment especially among youth; significant corruption misallocating funds; inadequate infrastructure restricting services and growth; and limited technology access. These issues are exacerbated by climate vulnerabilities in the key agricultural sector, which can lead to food insecurity, poverty, and malnutrition for many.
Corruption, unemployment, and poverty also risk social and political instability. Overall, Burkina Faso’s development is hampered by a combination of economic vulnerabilities and lack of resources, infrastructure, and technology that restrict living standards for much of the population.


Mali faces significant challenges to development and quality of life due to multiple interrelated factors.
With few natural resources and an undiversified economy reliant on gold and vulnerable agriculture, opportunities for growth are limited.
High population growth of over 3% annually strains scarce resources.
Weak governance, including ineffective institutions, corruption, and lack of basic services, undermines the economy, investment and living standards. Limited infrastructure increases business costs and hampers connectivity.
Over 40% of Malians live in poverty without adequate education, depriving many of skills and opportunities.
Climate threats like desertification and water scarcity reduce agricultural productivity and endanger food security. As a landlocked, hot country, farming and livestock rearing that many depend on is difficult.
The combined effects of these economic, social, environmental and geographic vulnerabilities create a cycle of underdevelopment that will be challenging to overcome without concerted efforts to strengthen institutions, promote inclusive growth, and boost resilience to climate risks.


Gambia faces significant development challenges due to multiple interconnected factors. With an estimated 1.1 million Gambians living in poverty, high poverty rates are exacerbated by economic difficulties like weaker growth and higher food prices. Limited natural resources constrain diversification.
Inadequate infrastructure, including limited electricity, water, and transportation, hampers growth and access to services. Past political instability and recent coup attempts have disrupted progress, as has the spread of HIV/AIDS. Climate change effects like worsening droughts and floods also threaten the economy.
As a small country dependent on agriculture, Gambia is vulnerable to these compounded stresses on its population’s health, livelihoods, and development. While democratic transitions are positive, overcoming such entrenched poverty will require concerted efforts across social, economic, and environmental domains to strengthen resilience against future shocks.

Sierra Leone

Sierra Leone is one of the poorest and underdeveloped countries in the world, and several factors contribute to this situation.
