Botswana at a crossroads

Young people want jobs and opportunities, education still needs to produce better learning outcomes, and while progress has been made against many infectious diseases, heart disease, cancer, and other chronic illnesses are becoming increasingly important health challenges.
Agricultural production has increased, yet land-tenure insecurity remains a challenge for many farmers and rural communities. Much remains to be done, but budgets are limited. No government—no matter how rich—can do everything at once.
The real question Botswana needs to ask is: How do we make every pula deliver the greatest possible benefit?
An important new initiative focused on Southern Africa is tackling exactly that challenge. From 15 to 17 July, top policy analysts from Botswana, Eswatini, Lesotho, Malawi, Namibia, Zambia and Zimbabwe gathered in Johannesburg to explore how cost-benefit analysis can help governments achieve far better outcomes with existing resources.
Cost-benefit analysis is a formalised way to distinguish effective policies from mediocre and poor ones. It identifies all costs and benefits of a policy over time — economic, social, and environmental — and translates them into present-day pula. This allows policy-makers to compare alternatives and prioritise investments that deliver the greatest return for society.
That matters because leaders everywhere face the temptation to promise everything to everyone. The UN Sustainable Development Goals, endorsed by Botswana and every other nation, illustrate the challenge. They aim to end poverty, hunger, and disease while addressing war, climate change, corruption, inequality, biodiversity loss, and much more. Yet achieving all these ambitions would require more than ten trillion additional dollars annually — a completely unrealistic amount of additional resources.
Every country must make difficult choices. Cost-benefit analysis does not tell democracies what to value; voters and elected leaders decide that. It simply helps identify which policies deliver the greatest impact for every pula spent.
For more than two decades, my think tank, the Copenhagen Consensus Centre, has worked with hundreds of the world's top economists, including several Nobel laureates, to identify the smartest investments. The evidence is striking: some interventions transform lives at remarkably low cost, while others consume vast resources for little benefit.
In Johannesburg, more than 140 top analysts from across the region, including more than 20 Botswanan delegates from the National Planning Commission and thirteen ministries participated in a three-day masterclass. They applied cost-benefit thinking to challenges such as education, healthcare, agriculture, infrastructure, climate adaptation, water management, and housing. The goal is not more reports, but practical analyses tailored to local realities that can inform politicians, media, and voters.
Consider education. World Bank estimates show that 51 percent of late-primary-age children in Botswana are not proficient in reading. What should be done? Experience from around the world offers valuable lessons. Some education reforms are enormously expensive yet achieve little. In the early 2000s, Indonesia sharply increased education spending, largely through higher teacher salaries. While costly, later studies found virtually no improvement in student learning.
Other approaches perform far better. Placing students in front of tablets with educational software one hour a day can dramatically increase learning, because it allows children to learn at their own pace and level. Large-scale studies consistently rank this as one of the most effective education policies. At relatively low cost it triples learning, delivering better student test scores and hence higher productivity and wages in adult life. On average, one pula returns 65 pula in long-term benefits. In fact, our education cost-benefit analysis in Malawi helped convince the government to scale tablets nationally to all 1-4 grade students, because the benefits are phenomenally higher than the costs.
Healthcare offers similar opportunities. High blood pressure is the world's leading risk factor for death, yet treatment can be simple and inexpensive. Research shows that expanding diagnosis and treatment across low- and lower-middle-income countries could save nearly one million lives annually. Every pula invested would generate about 16 pula in benefits.
Similar high-impact opportunities exist in child vaccination, agricultural productivity, e-procurement to reduce corruption, and stronger land tenure security. The objective is not to spend more money, but to spend it better.
The analysts attending the Johannesburg meeting also learnt to evaluate policies that are especially relevant to Botswana. This can help voters, media, and policy-makers demand better use of scarce resources. Cost-benefit analysis is not about replacing democracy with spreadsheets. It is about making trade-offs visible, reducing waste, and focusing attention on the most effective solutions.
In the years ahead, the countries that thrive won't necessarily be those with the largest budgets. They will be those that achieve the greatest results with the resources they have. By embracing cost-benefit analysis, Botswana can turn limited resources into lasting progress.
