ncreasing flood risks in Thailand are leading to new challenges for flood management and subsequently for livelihoods, which are still significantly agricultural. Policy makers prefer building flood protection infrastructure over utilizing non-structural measures like urban planning regulations to mitigate risks. We argue that unplanned urbanization intensifies flood risks and livelihood vulnerability and may even create new poverty patterns in peri-urban areas.

Agriculture influences and shapes the world’s ecosystems, but not always in a positive way. More than 2.5 billion people are globally involved as stewards of land and water ecosystems that constitute the natural resource base for feeding the current and future world population. Yet, conventional agronomic interventions based on ‘hard’ agricultural engineering compromise various eco-services that are required for sustainable agricultural development.

This profile provides an overview of climate risk issues in Uzbekistan, including how climate change will potentially impact five key sectors in the country: agriculture, water, tourism, ecosystems, human health, and infrastructure. The brief also includes an overview of historical and future climate trends in Uzbekistan, the policy context outlining existing climate risk strategies and plans developed by Uzbekistan, and a list of ongoing projects that focus on climate adaptation.

This in-depth study quantifies the spatio-temporal long-term land use/land cover change (LUCC) in the Mula Pravara river basin, and uncovers major drivers of these changes. The river basin is located in a semi-arid region of Maharashtra state, India. The study demonstrates the advantages of using satellite remote-sensing techniques to monitor LUCC, which is useful for predicting future land use development and for providing evidence to underpin adaptation strategies.

Widespread heat waves, floods, and droughts last year were a strong reminder of the threats posed by climate change. In the non-tropical dry areas where ICARDA works we are becoming accustomed to record high temperatures and increasing water scarcity year on year. Resilience and climate change adaptation are at the heart of ICARDA’s new Strategic Plan 2017-2026 – a bold and ambitious effort to harness cutting-edge science and deliver the tools and technologies that smallholder farmers need to maintain agricultural production and protect their livelihoods.

In the Tana River Basin in Kenya, six Regional Circulation Models (RCMs) simulating two Representative Concentration Pathways (RCPs) (i.e., 4.5 and 8.5) were used as input to the Soil and Water Assessment Tool (SWAT) model to determine the possible implications for the hydrology and water resources of the basin. Four hydrological characteristics – water yield, groundwater recharge, base flow and flow regulation – were determined and mapped throughout the basin for three 30-year time periods: 2020–2049, 2040–2069 and 2070–2099. Results were compared with a baseline period, 1983–2011.

A water and soil quality baseline study was carried out across the ~ 4500 km2 Vientiane Plain in Lao PDR. Eight water quality and nine soil parameters were analysed using field kits at 95 sites in March 2015. Elevated electrical conductivity and chloride were apparent at two sites due to geogenic leaching from the marine rock-salt present in some areas. Groundwater was acidic in most locations. Nitrate and faecal contamination were also observed from nitrogenous fertilizers (diffuse) and from leaky sewage pits (localised) respectively.

Storage of surface water is widely regarded as a form of insurance against rainfall variability. However, creation of surface storage often endanger the functions of natural ecosystems, and, in turn, ecosystem services that bene t humans. The issues of optimal size, placement and the number of reservoirs in a river basin – which maximizes sustainable bene ts from storage – remain subjects for debate. This study examines the above issues through the analysis of a range of reservoir con gurations in the Malwatu Oya river basin in the dry zone of Sri Lanka.

Participatory groundwater management is increasingly being recognised for its ability to address the challenges of equity, efficiency and sustainability. It can particularly help with effective engagement at the grassroots level for monitoring, recharging and managing the groundwater as a common pool resource. The main aim of this article is to discuss the training and management process used and the lessons learnt from a participatory groundwater management project, titled Managing Aquifer Recharge and Sustainable Groundwater Use through Village-level Intervention (MARVI).
