Researchers focus on collapsed SA squid fishery

PORT ELIZABETH: The collapse of the local squid fishery on the south-east coast of South Africa in 2013 has prompted an international body of scientists and policymakers to meet this September. The group will bring together different research disciplines to discuss this small but high-value export fishery, which collapsed in the summer of 2013 and 2014.

Kenya: mini-hydro plants need strong rules, leaders

Small-scale, community-managed hydro power schemes in remote rural Kenya function well if they are run by strong leaders, and have firm rules for how the scheme should be managed. When members of the mini-grid system know they will be disconnected from the grid for breaking those rules, they tend to cooperate more willingly.

Micro-hydro may boost rural Kenyan economies

For the average rural Kenyan, having a fully charged mobile phone isn't just a luxury that allows them to make phone calls. It’s a complete office for running their small businesses. So when people have access to an electricity source that allows them to keep their phone batteries charged, it means the entire local economy benefits.

Kenyan policy landscape ‘fertile’ for micro-hydro

The mountainous countryside in Kenya is ideally suited for small-scale hydro power plants, particularly for communities that are too far from the national electrical grid, or where the infrastructure and connection costs are too high. But the government of this East African country has not exploited its hydro power opportunities, something which environmental economist Mary Karumba hopes to change as she returns to government service after completing her doctoral studies in South Africa.

Behavioural Nudges for Water Conservation: Experimental Evidence from Cape Town

The City of Cape Town has been working with EPRU to find an evidence-based answer to which methods are most effective in encouraging more prudent water use by the public. Prof Martine Visser, Dr Kerri Brick, and Johanna Brühl are behavioural economists at EPRU. The EPRU team was supported by Samantha De Martino from Sussex University, and Jorge Garcia from Cicero in Norway. The results assist the municipality to design policy that will help manage the city’s water supplies in an increasing climate change-stressed future. The study focuses on identifying which incentives best motivate households of different income levels to reduce their consumption.

Greening Africa’s growing cities

Africa’s cities growth might have kicked off a bit later than many other developing world countries, but they are growing fast. This presents an opportunity to do so in a way that creates ‘a more harmonious relationship between their natural and built environments. This is according to a new report by the World Bank, which concludes that ‘focused action is necessary’ in order to avoid ‘largely unchecked (negative) impacts on the natural environment, and the degradation of natural assets and ecosystems within African cities’.

Can Canadian fisheries management work for South Africa?

A South African research economist recently returned from a five-month sabbatical to British Columbia where he explored whether Canada’s approach to managing river salmon, and to a lesser extent sturgeon, could be replicated successfully for in-shore coastal fisheries management here.

Nudging people to save water and power

Having competitions between staff, appointing water-saving ‘champions’ in your office block, or recognising people for their efforts to use energy more sparingly: these are small but powerful ways that cities can encourage people to cut their water and electricity use. Now, behavioural economists at the University of Cape Town’s Environmental Policy Research Unit (EPRU) are about to embark on a three-year collaboration with Cape Town’s utility managers, to see how they can implement these ideas across the city, and get them written into municipal policy.

Carrot-or-stick to ‘nudge’ water-wise behaviour

There are many ways for city utility departments to get people to voluntarily reduce their water use during a time of drought and water shortages. Some are positive, ‘carrot’ approaches; others might be ‘stick’ approaches to enforce certain behaviours. Now, the City of Cape Town is working with behavioural economists to find an evidence-based answer to which methods are most effective.

Public praise for water-wise behaviour: a lesson for city managers

A team of behavioural economists has an important message for City of Cape Town’s water managers, who are currently implementing tight water restrictions after three years of drought in the region: if the city publicly praises individuals and households for their water saving efforts, this will get people to voluntarily contribute to even greater water-wise behaviour.

Market mechanisms to nudge better watersheds management

The traditional approach to managing watersheds globally is to do so using state regulations, or through publicly funded initiatives. A recent analysis by the United Nations Environment Program (UNEP) shows that using market mechanisms to incentivise better watershed management is a good complement to these more widely used methods.

SA environmental policy should have climate change focus

CAPE TOWN: The South African government has drawn up some of the most advanced environmental laws and policies on the continent, since its transition to a democratic state in 1994. In a recent overview of these, University of Cape Town (UCT) resource economist Dr Jane Turpie has identified key areas were future research is needed, in order to boost this policy further, with responses to climate change being a key theme.

SA’s ocean economy reviewed

CAPE TOWN: South Africa’s oceans and beaches boost the country’s economy by roughly 35 percent, in terms of the ‘goods and services’ they provide. This is highlighted in a report released recently by the local branch of the Worldwide Fund for Nature (WWF), which gives an overview of the economic value of South Africa’s marine environments.

How to drive water saving amongst office staff

CAPE TOWN: Appointing a water-saving ‘champion’ in an office block context could be one way that municipalities and companies in South Africa can respond quickly and cheaply to the water restrictions facing many parts of the country, following two years of severe drought.

Putting a value on Cape Town’s green spaces

The people of Cape Town are being given a chance to tell city managers just how much they value the natural green spaces, manicured parks, sports fields, and street trees in their neighbourhoods. And what they say may help park authorities decide how to prioritise their spending, at a time when there is growing pressure to develop open green spaces for housing or business opportunities.

Risk in small farming: winning Masters’ thesis

CAPE TOWN: A study of how small-scale farmers in the Western Cape, South Africa, shape their decisions around using conventional or organic farming methods, based on their perceived risks, has won an economics Masters student at the University of Cape Town (UCT) an award for the best thesis in her year.

Surprising finding: water heating behaviour in SA

CAPE TOWN: The single most effective thing that South Africans can do to reduce their energy use related to heating water in their homes, is to switch off hot water cylinders half an hour before they are most likely to bath or shower. Those people who do switch their cylinders on and off during the day, as an energy saving measure, tend to turn them off after the geysers have refilled and reheated, which is wasteful of energy.

Planning for climate responses’ unintended fallout

CAPE TOWN, SOUTH AFRICA: When home owners at a seaside residential complex in Milnerton, Cape Town, decided to pile up sandbags between the beach and their gardens in the early 2000s, their intention was to stop the high tide from eating away at their plots during storm surges. What they didn’t anticipate was that this erosion control measure would make their property prices fall, reduce beach space, drive away tourists, and leave the beach strewn with litter.

Better banking, communications, needed in Southern Africa

JOHANNESBURG, SOUTH AFRICA: When a touring group of 289 mountain bikers needs to cross legally from Botswana into Zimbabwe, and then South Africa (SA), far from any official border posts, it means setting up informal but bureaucratically-sound passport control points in dry river beds or on dirt tracks.

Is there an economic case for fracking?

WORCESTER, SOUTH AFRICA: If the South African government gives the green light for private energy companies to begin extracting shale gas using the method of hydrological fracturing, or ‘fracking’, will it have economic benefits for the region and the country? And if so, could these be offset by the cost of the potential negative impacts to other sectors and communities in the water-scarce Karoo, where fracking is being considered?

Putting a price tag on natural water purification

CAPE TOWN, SOUTH AFRICA: Nature can help to purify the water we drink. When a forest upstream of a water treatment plant is intact and healthy, the water arriving in the plant can be of  better quality than if the forest has been heavily harvested or clear-felled. Better quality water arriving in the plant, means fewer chemicals needed to clean the water, and the purification costs are therefore lower.

Standardising the valuation of nature’s services

CAPE TOWN, SOUTH AFRICA: A working group of resource economists met in Cape Town this April to agree on the methods they will use in order to contribute to the development of a standardised national accounting system for valuing ecosystem services.

Workshop on the standardising of accounting system for nature’s services

When a country wants to tally up its economic performance, it generally uses ‘gross domestic product’ as its measuring stick. That’s a global standard of accounting, agreed upon according to the United Nations’ ‘systems of national accounting’, which allows all countries of the world to compare apples with apples in their economic reporting.

‘Time of use’ tariffs in the spotlight

SOUTH AFRICA: Charging a premium for peak-time electricity could be an effective way of getting city consumers to spread their power use more evenly throughout the day, helping the national utility to manage the country’s grid more effectively.

Smart device cuts geyser energy by up to a third

Stellenbosch, South Africa: An experimental geyser control device, which is operated via the internet a smart phone app, has the potential to cut household water heating by up to 30 percent without users noticing a change to their hot water use habits.

Tracking water use trends in SA’s ‘mother city’

CAPE TOWN, SOUTH AFRICA: In informal settlements and lower income homes in Cape Town, most household water use is for doing laundry. However, in the middle class suburbs, it’s mostly for showering and topping up swimming pools. This finding, from a recent municipal survey in five suburbs across South Africa’s ‘mother city’, underpins an ongoing drive to educate city residents about their water use patterns, in order to urge behaviour change.

Utilities-based funding model is a problem in SA cities

CAPE TOWN: South Africa’s bigger cities get a large amount of their revenue from the sale of electricity and water to consumers. And owing to the pricing structure of these services, cities earn more from large-volume users, and use this revenue to cross-subsidise smaller volume users, who often fall in lower income communities.

Economists hail Cape wetland conservation

Local economics researchers have hailed the announcement this month that the City of Cape Town will reverse a decision to sell a section of the Princess Vlei wetland near Diep River to developers, who planned to build a shopping mall.

Sharing the Berg River’s contested waters

CAPE TOWN, SOUTH AFRICA  The water flowing down the Berg River, towards the Cape West Coast and Saldanha Bay, is the lifeblood of two competing sectors: heavy industry, and agriculture. But as demand for this limited resource grows, how do the water managers decide who gets access to it, when the water in the river is already fully allocated between existing users?

Knowing angler ‘hotspots’ could help enforce catch limits

Anglers along the South African coastline choose their fishing spots on the likelihood of catching the most fish, rather than how far they have to walk to get to the spot, or weather conditions. Knowing where these fishing ‘hotspots’ are could help authorities enforce catch limits, as line fish stocks have depleting dramatically in recent years.
