As Cape Town faces the worst drought in a century, the city may need to shut off running water to homes and businesses in an effort to crisis-manage the last remaining water in the metropole's dams. ‘Day Zero’, as it has become known, is expected to arrive on 9 July, and may need to stay in place for three months.
Turn on the water tap in Cape Town, South Africa in March, and nothing will come out. For the Environment for Development researchers at the University of Cape Town, there’s nothing faraway about their work to help the city conserve water during this drought emergency.
This year the EfD annual meeting will be held in Addis Ababa, Ethiopia from: October 27-30, 2017. It is hosted by the Environment and Climate Research Center (EfD - Ethiopia) and the EfD Secretariat. The EfD annual meeting is a forum to bring together researchers from all EfD centers and their collaborators. EfD would also like to attract key stakeholders for exchange of research ideas. Updates for participants will be displayed here.
Healthy natural landscapes such as veld, wetlands, rivers, and estuaries across South Africa generate value to the economy amounting to at least R275 billion per year, a new study by economists at the University of Cape Town (UCT) has found.
The Working Group in African Political Economy (WGAPE) is pleased to announce a special international meeting to be held January 26-28, 2018 at New York University-Abu Dhabi.
If Cape Town’s urban surfaces are designed to be porous and water-catching, it could help meet many of the city’s water needs through recharging the Cape Flats aquifer, while also helloing to manage rainy season flooding and stormwater pollution challenges.
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.
Applauding people publicly for their successful efforts to reduce water use at home may be an effective means of driving water-wise behaviour across a city.
The African Economic Research Consortium (AERC) In Partnership with GIZ and the World Bank are calling for Fellowships for a PhD specialization Course on Land Economics and Governance (Jan 7- Feb 11, 2018).
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.
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.
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.
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.
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’.
Duke welcomed over 70 scholars and practitioners from 15 countries for the second annual Sustainable Energy Transitions Initiative (SETI) Meeting, May 9-11, 2017.
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.
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.
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.
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.
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.
PORT ELIZABETH: As long as farmers and wildlife have vied for their share of the veld here in South Africa, there has been a conflict, as the inevitable presence of wild predators has resulted in livestock loss.
SETI (http://seti.duke.edu/) invites concept notes to seed collaborative research related to energy transitions. We particularly welcome proposals for work related to the SETI priority themes, including: Consequences of energy poverty, defined as a lack of reliable access to electricity and other modern fuels Drivers of the energy transition in low- and middle-income contexts, including lessons from past experiences Impacts of energy transitions at various scales (households, firms, and the regional and global environment) Policy levers and solutions to speed the energy transition; and analysis of their effectiveness Notable gaps in research on energy transitions
We are very pleased to announce that the second meeting of the Sustainable Energy TransitionsInitiative (SETI) will take place May 9-11 at Duke University (Durham, NC).
Duke Kunshan University is now accepting applications for the new international Master of Environmental Policy (iMEP) Program. The iMEP program is a two-year degree offered jointly by Duke’s Sanford School of Public Policy and Nicholas School of the Environment. Students will study core courses in both environmental management and public policy at Duke Kunshan University (China) and Duke University (United States). We would really appreciate it if you could share this information with people who might be interested.
Two Massive Online Open Courses (MOOCs) on Water Supply and Sanitation Policy in Developing Countries
On January 29th 2017 the Alliance Manchester Business School at the University of Manchester (UK) will launch a sequence of two Massive Online Open Course (MOOC) on Water Supply and Sanitation Policy in Developing Countries, taught by Professor Dale Whittington and Dr Duncan Thomas.
The Centre for Scientific and Industrial Research (CSIR) recently released a scientific assessment of the risks and opportunities of shale gas mining, which is proposed for parts of the Karoo region of South Africa.
Healthy forests in sub-Saharan Africa are an important source of wild pollinators, and thus support agricultural productivity and food security in the region, a conference in the Kenyan capital, Nairobi, heard this November.
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.
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.
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.
South Africa’s official unemployment rate is over 25 percent. Amidst a virtually stagnant economy, it is unlikely that this will drop to the desired developing world target of below 10 percent in the foreseeable future.
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.
CAPE TOWN: A study into the structure of the South African hake fishing industry, which finds that keeping the industry serviced by bigger companies is less environmentally hazardous, has won an economics student at the University of Cape Town this year’s best Honours level thesis in the School of Economics.
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.
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.
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.
JOHANNESBURG, SOUTH AFRICA: Tourism in the Southern African Development Community (SADC) is being held back largely by failures within other sectors, according to a leading tourism analyst and economist here.
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.
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?
CAPE TOWN, SOUTH AFRICA: Tanzanian households, who are heavily dependent on small-holder and often subsistence farming for their livelihoods, benefit from the free ecosystem services offered by wild pollinators, which boost agriculture yields.
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.
CAPE TOWN, SOUTH AFRICA: Resource economists from seven countries met in Cape Town this April, in an effort to find a common method for calculating the value of urban green spaces, such as parks, within their region’s main cities.
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.
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.
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.
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.
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.
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.
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.
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?
