Strategies for adapting to climate change in Costa Rica

Read María A. Naranjo' opinion article (Estrategias de adaptación al cambio climático en Costa Rica) in "La Nación" (January 28th), related to the EfD Central America Project "Small Farmers' Determinants of Private Adaptation to Climate Change Strategies" (Spanish only).

Climate change impacts on Namibia’s natural resources and economy

Climate change is likely to exacerbate the dry conditions already experienced in southern Africa. When rainfall does come, it is likely to be in bursts of greater intensity, leading to erosion and flood damage. However, these predictions have had very little influence on policy in southern African countries.

Are demand elasticities affected by politically determined tax levels?

Raising the price of fossil fuels is a key component of any effective policy to deal with climate change. Just how effective such policies are is decided by the price elasticities of demand. Many papers have studied this without recognising that not only is there a demand side response: quantities are decided by the price but also there is a reverse causality: the level of consumtion affects the political acceptability of the taxes which are the main component of the final price. Thus prices affect consumption levels, in turn, have an affect on taxes and thus consumer prices. This paper estimates these functions simultaneously to show that there is indeed an effect on the demand elasticity.

    Lessons from Cape Town drought may help developing world cities

    In January 2018, the South African city of Cape Town came within three months of running out of municipal water, following the worst drought in over a century. ‘Day Zero’ was the day when water managers would initiate emergency rationing measures, shutting off water to homes and businesses outside of the central city.

    Adaptation to Climate Change Can Improve Supply of Body Energy Needs and Reduce Malnutrition

    Researchers at EfD-Kenya have found new evidence that nutritional poverty is linked with climate change and variability. ‘In Kenya and other African countries, a majority of farmers depend on rainfall that is increasingly unpredictable,’ said Dr Richard Mulwa, Senior Research Associate at EfD-Kenya and one of the lead investigators in the study. ‘Also, increasing temperature reduces food production. Therefore, it is critical for these farmers to change their farming practices in response to climate change’.

    Nature helps farmers cope with climate change

    Central America has more than 2.3 million families depending on agriculture and natural resources for their livelihoods, making them vulnerable to climate change risks such as rising temperatures, extreme events such as drought and flooding, and also crop diseases. Researchers associated with the Swedish-based Environment for Development (EfD) initiative are running an ecosystems-based adaptation project in Guatemala, Honduras, and Costa Rica that supports smallholder farming communities in adapting to changing conditions. This project scales up the needs and opportunities of smallholders to promote changes in public policies at a regional level.

    Climate change is affecting food security

    A recent study in Kenya shows that climate change and variability will increase food insecurity and that different food crops will respond differently to climate change variables. The study also highlights the different factors influencing food insecurity in a changing climate. This is important information for farmers as well as the government.

    Sustainable energy transitions to support the Climate-Resilient Green Economy Strategy

    Ethiopia aims to build a green economy and to follow a growth path that fosters sustainable development. Through the development of its Climate-Resilient Green Economy (CRGE) strategy, which is based on carbon-neutral growth, it envisions attaining middle-income status by 2025. Improving the productivity of the agricultural sector, protecting forests, expanding the coverage of electric power from renewable sources of energy and transitioning into modern and energy-efficient technologies are the main pillars of Ethiopia’s CRGE strategy.

    Farmers are willing to pay for irrigation

    How can charging money for something that was free be a good idea for poor farmers? It turns out that pricing irrigation water will help improve Ethiopian farmers’ efficiency in water use, increase agricultural and food production, and make the population less vulnerable to climate change. One unique contribution of environmental economists is that they collect data from the field and then calculate what natural resources are really worth.

    Rural people must deal with threats to drinking water

    People in Central America’s rural areas will face a 20 percent decline of drinking water availability by 2050, estimates show. EfD researchers are now collecting information from 8 000 households in Nicaragua, Guatemala and Costa Rica. The primary aim is to map capabilities and obstacles for communities to adapt, and to provide community leaders tools and skills to respond to drier scenarios. EfD findings also support governmental adaptation policies.

    Mixed strategy farming is best in face of climate change

    The South African node of the EfD network, the Environmental Economics Policy Research Unit at the University of Cape Town is working towards influencing South African policy in four key areas: climate change, biodiversity conservation, marine fisheries, and energy. One of the recent studies identified mixed farming as a crucial strategy to adapt to climate change, particularly for small farmers.

    EfD Researchers Suggest Solutions to Reduce Traffic in Beijing

    A plan to reduce automobile traffic in Beijing was in the hands of the city’s mayor in late 2013. EfD China played a major role in figuring out what strategies would – and would not  – be likely to reduce the pollution and congestion that Beijing residents have been facing as a result of economic growth.

    Climate change research in COMESA region

    EfD-Kenya fellows Wilfred Nyangena and Geophrey Sikei, were engaged in the review and synthesis of literature on climate change research in the COMESA region and how it has influenced policy.

    Climate Change hits Africa the hardest – what can be done?

    Ethiopia risking average income cut of 30 percent The impacts of climate change on agricultural productivity may reduce the Ethiopian average income by as much as 30 percent within the next 50 years. This and other EfD findings on how climate change is hitting Africa, and in particular Ethiopia, were presented to 60 workshop participants from government, NGOs and multilateral organizations assembled in Addis Abeba. Strategies for adaptation, mitigation and a stronger position in international climate negotiations were discussed.

    EfD research addresses Beijing´s congestion and air pollution

    Beijing is the world´s most congested city as measured by average vehicle speed. It is also one of the most air polluted cities, with a substantial part of the emissions coming from vehicles. To find effective policy instruments to address these serious urban challenges, Environment for Development in China/the Environmental Economics Program in China (EEPC) and Beijing Transportation Research Center are collaborating in a research program.

    Research-policy dialogue improves drinking water management

    “To do high-quality research, you need to find out what policy makers need and nurture the interaction,” says Maria Angelica Naranjo, EfD researcher in Central America. Her research colleagues Roger Madrigal and Francisco Alpízar are exploring why some Costa Rican communities are successful in drinking water management while others are not. Policy makers and local communities are already using some of the researchers’ recommendations to bring change.
