HUMAN WRONGS WATCH

(UNCCD)* — Recent drought-related data based on research in the past two years and compiled by the UN point to “an unprecedented emergency on a planetary scale, where the massive impacts of human-induced droughts are only starting to unfold.”

UNCCD

According to the report, ‘Global Drought Snapshot,’ launched by the UN Convention to Combat Desertification (UNCCD) at the outset of COP28 climate talks in the UAE, few if any hazard claims more lives, causes more economic loss and affects more sectors of societies than drought.

UNCCD is one of three Conventions originated at the 1992 Earth Summit in Rio de Janeiro. The other two address climate change (UNFCCC) and biodiversity (UN CBD). 

Says UNCCD Executive Secretary Ibrahim Thiaw: “Unlike other disasters that attract media attention, droughts happen silently, often going unnoticed and failing to provoke an immediate public and political response. This silent devastation perpetuates a cycle of neglect, leaving affected populations to bear the burden in isolation.”

“The Global Drought Snapshot report speaks volumes about the urgency of this crisis and building global resilience to it.  With the frequency and severity of drought events increasing, as reservoir levels dwindle and crop yields decline, as we continue to lose biological diversity and famines spread, transformational change is needed.” 

“We hope this publication serves as a wake-up call.”

Drought data, selected highlights:

• 15–20%: Population of China facing more frequent moderate-to-severe droughts within this century (Yin et al., 2022)
• 80%: Expected increase in drought intensity in China by 2100 (Yin et al., 2022)

Water conditions

• 75%: Reduction of cargo capacity of some vessels on the Rhine due to low river levels in 2022, leading to severe delays to shipping arrivals and departures (World Economic Forum, 2022)

• 2,000: backlog of barges on the Mississippi River in late 2022 due to low water levels, causing $20 billion in supply chain disruptions and other economic damage (World Economic Forum, 2022)
• 2–5 times: Acceleration of long-term rates of groundwater-level decline and water-quality degradation in California’s Central Valley basins over the past 30 years due to drought-induced pumpage (Levy et al., 2021) 

Social dimensions 

• 85%: People affected by droughts who live in low- or middle-income countries (World Bank, 2023)
• 15 times: Greater likelihood of being killed by floods, droughts and storms in highly vulnerable regions relative to regions with very low vulnerability, 2010 to 2020 (IPCC, 2023)
• 1.2 million: people in the Central American Dry Corridor needing food aid after five years of drought, heatwaves and unpredictable rainfall (UNEP, 2022)

Remedies

• Up to 25%: CO2 emissions that could be offset by nature-based solutions including land restoration (Pan et al., 2023)
• Almost 100%: Reduction in the conversion of global forests and natural land for agriculture if just half of animal products such as pork, chicken, beef and milk consumed today were replaced with sustainable alternatives (Carbon Brief, 2023)
• 20 to 50%: Potential reduction in water waste if conventional sprinkler systems were replaced by micro-irrigation (drip irrigation), which delivers water directly to plant roots (STEM Writer, 2022).
• 20%: EU’s land and sea areas to be made subject to restoration measures by 2030, with measures in place for all ecosystems in need of restoration by 2050 (European Council, 2023)
• $2 billion: investment by AFR100 in African organizations, businesses and government-led projects, announced this year with further anticipated investments of $15 billion to foster the restoration of 20 million hectares of land by 2026, generating an estimated $135 billion in benefits to around 40 million people. (Hess, 2021)
• 6: Riparian countries (Benin, Burkina Faso, Cote d’Ivoire, Ghana, Mali and Togo) participating in the Volta basin Flood and Drought management project, the first large-scale, transboundary implementation of Integrated Flood and Drought Management strategies, including an End-to-End Early Warning System for Flood Forecasting and Drought Prediction (Deltares, 2023)
• ~45%: global disaster-related losses that were insured in 2020, up from 40% in 1980-2018. However, disaster insurance cover remains very low in many developing countries (UNDRR, 2022)
• 50 km: the resolution of the water distribution maps thanks to a recently-developed method of combining satellite measurements with high-resolution meteorological data, an major improvement from the previous 300 kilometers resolution (Gerdener et al., 2023)

The report was unveiled at a high-level event with the International Drought Resilience Alliance (IDRA) in Dubai (webcast at www.youtube.com/@THEUNCCD, 16:00 Dubai time / 12:00 GMT.  It is part of UNCCD’s series of Land and Drought Dialogues at COP28: https://bit.ly/3Gh7GZd). 

Launched by the leaders of Spain and Senegal at COP27, IDRA is the first global coalition creating political momentum and mobilizing financial and technical resources for a drought-resilient future.

Australia, Colombia, Italy and the Union of Comoros, together with the Commonwealth Secretariat and other major international organizations, are being announced at COP28 as IDRA’s latest members, bringing the Alliance’s total membership to 34 countries and 28 entities.

Additional highlights from the report:

Several findings in this report highlight land restoration, sustainable land management and nature positive agricultural practices as critical aspects of building global drought resilience. By adopting nature-positive farming techniques, such as drought-resistant crops, efficient irrigation methods, no-till and other soil conservation practices, farmers can reduce the impact of drought on their crops and incomes.

Efficient water management is another key component of global drought resilience. This includes investing in sustainable water supply systems, conservation measures and the promotion of water-efficient technologies.

Disaster preparedness and early warning systems are also essential for global drought resilience. Investing in meteorological monitoring, data collection and risk assessment tools can help respond quickly to drought emergencies and minimize impacts.  Building global drought resilience requires international cooperation, knowledge sharing as well as environmental and social justice.

“Several countries already experience climate-change-induced famine,” says the report.

“Forced migration surges globally; violent water conflicts are on the rise; the ecological base that enables all life on earth is eroding more quickly than at any time in known human history.”

“We have no alternative to moving forward in a way that respects the planet’s boundaries and the interdependencies of all forms of life. We need to reach binding global agreements for proactive measures that are to be taken by nations to curtail the spells of drought.”

“The less space the developed human world occupies, the more natural hydrological cycles will stay intact. Restoring, rebuilding and revitalizing all those landscapes that we degraded and destroyed is the imperative of our time. Urban intensification, active family planning, and curbing rapid population growth are prerequisites for societal development that respects planetary boundaries.”

About 

The United Nations Convention to Combat Desertification (UNCCD) is an international agreement on good land stewardship. It helps people, communities and countries create wealth, grow economies and secure enough food, clean water and energy by ensuring land users an enabling environment for sustainable land management. Through partnerships, the Convention’s 197 parties set up robust systems to manage drought promptly and effectively.

Good land stewardship based on sound policy and science helps integrate and accelerate achievement of the Sustainable Development Goals, builds resilience to climate change and prevents biodiversity loss.
