How Integration Can Defeat Disease & Poverty

A number of NGOs, including Tearfund, WaterAid, Action against Hunger, End Water Poverty, PATH and Action for Global Health, have recently produced an interesting piece of research called 'Join up, Scale up - How integration can defeat disease and poverty' The research highlights cases where an integrated approach across sectors produced a greater impact, than a less integrated approach. For example, water and sanitation projects being joined with health, income generation or food production projects. In one example from the Democratic Republic of Congo, a water and sanitation project was joined with a project working to end violence against women - which often occurs when women are walking to get water.

GfGD believe in a holistic approach, understanding the interactions between sectors - and it is great to read of many projects in which professionals from different sectors are communicating and working together for maximum impact. You can download the report from Tearfund's website or read their blog introducing it on Tearfund's Just Policy blog site.

Applying Technologies from Developed to Developing Countries

While there is a significant need for geologists to engage with international development, there's also a tremendous importance in developing tools, skills and technology in developed countries. In many situations, businesses, universities and governments of developed countries are willing to invest significant amounts of money in developing technologies and tools. This investment can often not be matched by many developing countries, but the technologies developed could eventually have a global use and be of benefit to millions in poverty. 

For example, the intrusion of saltwater into freshwater aquifers is a global problem, and a problem likely to increase if and when sea-levels rise, and coastal cities grow. Developing the technology to monitor and control this influx will require investment, research and development - and yet the outcome could be a relatively cheap technology that can be used globally. Coastal aquifers in the UK and Tanzania could equally benefit from similar technology.

Typical Coastal Aquifer (From: USGS)

A further example was published in the New York Times today, analysing the most and least safe cities affected by a number of natural hazards (including weather events such as tornadoes, hurricanes, hail and storms, floods and droughts, and earthquakes). The study gives an 'overall risk' map combining these events, and separate maps for hurricanes, tornadoes and earthquakes. Little information is given on how the 'overall risk' map was generated... the individual maps were generated using historical data and assessments from the USGS. The lack of description and methodology means it is hard to critically analyse the data within this multi-hazard risk assessment, and how it has been compiled. The development of software tools and methodologies for developed countries with a high risk of damage by multi-hazards (e.g. Japan, USA, China etc) could be extremely useful for developing countries which also suffer from a range of natural disasters such as landslides, floods, droughts, earthquakes (e.g. Nepal, Uganda etc).

The Role of Geologists in Humanitarian Emergency Response

As reported on Monday, a review into the UK’s response to humanitarian emergencies has been conducted by Lord (Paddy) Ashdown and released yesterday. The review outlines ways in which the UK can improve its response to such emergencies, and anticipate such emergencies. Incorporating these into the core of DFID’s work is crucial – making sure their development work and humanitarian assistance are integrated. 

The report highlights seven threads to the approach needed to be adopted including:

1.   A more anticipatory approach – using science to aid in the prediction of and preparation for such emergencies. It is important to be preparing for disasters as well as reacting to them (including equipping at-risk governments/civil society with the means to act).

2.   Resilience – working with local people to strengthen the community’s capacity to be resilient to an event. This was highlighted as an area that needs to become much more central to DFIDs development activities. Resilience will mean the damage is less lasting and communities can recover more quickly.

The report cites an interesting example where Mozambique asked in 2006 for £2million pounds to invest in preparing for the impacts of floods – which it could not receive. Soon after, the international community had to spend £60million pounds responding to a flood season

3.   Improve the strategic, operational and political leadership of the international humanitarian system, including pushing for reform within the UN’s response procedures.

4.    Innovate to become more efficient and effective – using the best of new technologies and science, new processes and practices, and new ideas from those affected. More investment needs to happen in research and evidence.

5.   Increase transparency and accountability towards both donor and host country populations. More conversation needs to occur between donors and communities to ascertain exactly what they need, how they can be helped and who can help them. Vulnerable people can often be overlooked. On the flip side, measuring the impacts of resources is a key way to ensure accountability to donors.

6.   Create new humanitarian partnerships to allow DFID to better influence and work within an increasingly complex humanitarian system. The need for multilateral work in this area is crucial, and while DFID is commended for adopting this approach it suggests they should work to enable new partnerships with emerging nations, NGOs, faith groups etc

7.   Defend and strengthen the humanitarian space – humanitarian workers should be granted access and protection as they give assistance in areas affected by conflict. DFID should work with agencies that can access and help those in need and humanitarian aid should not be politicised.


Over the past couple of years we have witnessed some awful natural disasters that have required significant humanitarian assistance. Earthquakes have rocked developing countries such as Haiti, as well as more developed countries such as Chile, New Zealand and Japan. Floods have been catastrophic in Pakistan, and Australia, and large landslides and flooding have hit Brazil. The way in which the UK responds to such disasters – especially in developing countries where the effects disproportionately affect the population is very important. The UK is the second largest bilateral global humanitarian donor, although in terms of its percentage of GNI trails behind a number of countries.

The results of the Humanitarian Emergency Response Review are broadly welcomed. As developing countries are urbanising, vulnerability to disaster is in many ways increasing and steps need to be taken to ensure the international community’s response to disasters matures, as well as the anticipation of disasters and building of resilience develops.

Geologists have a very important role to play in the factors of anticipation, resilience and innovation.

ANTICIPATION: In disasters such as earthquakes, volcanic eruptions, floods, landslides etc – geologists study the science of how they occur and can use their skills to understand and recognise vulnerable areas. While prediction is not always possible, understanding of vulnerable areas, frequency and magnitude can be understood to a certain degree

For example: The study of palaeoseismology can provide information on the frequency of historical earthquakes and their magnitude. This information can help inform governments and civil societies to prepare. The UK for example knows to expect earthquakes up to approximately magnitude 6 following the M5.3-5.9 earthquake in the late 1500’s (although this size is extremely rare (See here for more info on UK Seismic Hazard). In Chile, they must prepare for earthquakes significantly bigger than this, at Magnitude 9 or greater.

Data for some hazardous areas can be significant, but often in developing countries the data is gathered at a much slower rate, and so is less sizeable, as governments can invest less in their own monitoring and evaluation programmes. Geologists can play a major role in building up knowledge of the mechanisms of hazards, their appearance in history and the likely impacts of the hazard.

RESILIENCE: Building resilience to minimise the damage of the hazard is another area of humanitarian work that geologists can play a crucial role in. The education of communities to understand how hazards are triggered can help people recognise the warning signs for a number of hazards. Understanding the relationship between landslides and water can help communities construct simple drainage mechanisms, avoid the undercutting of slopes and ensure deforestation doesn’t occur on vulnerable slopes. Understanding the relationship between earthquakes and tsunami’s was not understood by many communities in the tragic 2004 Boxing Day tsunami in Indonesia, understanding the risk of a tsunami following an earthquake can give communities that vital extra time to move inland. Education can involve a community led, participatory approach in order to build a sustainable programme.

As well as education, improving physical structures can develop resilience. Geologists can play a major role in identifying which areas of the city are must vulnerable and how resilience methods can change from place to place. The types of buildings required to withstand earthquakes will differ from one rock-type to another for example.   

INNOVATION:  With regards to innovation, geologists are doing various pieces of research, and must do more, to improve the understanding and preparation for humanitarian emergencies. Geologists and other scientists must work closely with social scientists in order to develop and improve better risk assessments for developing countries – including the development of multi-hazard risk assessments. Research into the effects of global climate change at a local scale, and mitigating any risks, is fundamental research to be collated, as is how increased urbanisation will impact the consequences of disasters.

The response DFID gives to this review, and the speed at which they respond, will be very interesting. DFID must take seriously the importance of Disaster Risk Reduction, and the economic benefits of it, and ensure it is integrate into the core of its work. The crucial role that scientists can play in this sector must also be recognised further – not only in terms of health and agriculture – but also with regards to geology and engineering.

The Severity of Climate Change

(c) AAAS 2011
As reported by the National Science Foundation (USA), the latest edition of Science (25th February 2011) includes a fascinating piece titled 'How Severe Can Climate Change Become?'

An international team of scientists led by Curt Stager of Paul Smith's College, New York have been examining cores of sediments derived from Lake Tanganyika, and other locations across Africa. These sediment cores can be used to produce models of past climate (palaeoclimate), giving an indication of what conditions were like tens of thousands of years ago.

Results of this research found that around 15-18000 years ago a megadrought occurred in which Lake Victoria (below right) dried as did other lakes and major rivers such as the Nile. The effects of this would be devastating for huge numbers of people. It is conjectured that the cause of this megadrought was a warming event, and the melting of huge amounts of ice, releasing significant amounts of water into the North Atlantic, altering global climatic patterns.

The report highlights that there is much less ice today that could melt and enter the North Atlantic, and hence it is unlikely that a megadrought on the same massive scale could occur, however the results give an indication of some of the effects global warming could have on developing nations such as Tanzania, Uganda, Ethiopia etc. Droughts much smaller than the megadrought reported in this paper do and will have a significant effect on the lives of many poor communities.
