In the region of central Asia and Caucasus (CAC), collection, assessment and sharing of information on water and land resources, previously under central command of the Soviet Union, have been fragmented during the past decades. In fact, the regional program has supplemented an important role in supporting and facilitating data assessment and knowledge sharing. The presentation will highlight some results from the recent assessments of water resources and climate change impact, ground water storage capacity as an alternative water source, human impact on water and soil quality, marginal water use, and ecosystem-based intervention for improvement of water and land productivity specifically around the Aral Sea.

Dans les régions de l’Asie centrale et de Caucasus (CAC), la collecte, l’évaluation et le partage des données sur les ressources en eau et les terres, initialement sous le contrôle de l’Union Soviétique, ont été fragilisés durant les quatre dernières décennies. En effet, le programme régional a joué un rôle important en supportant et en facilitant l’analyse des données et le partage des connaissances. La présentation montrera certains résultats des récentes évaluations sur ressources en eau et l’impact du changement climatique, les capacités de stockage des eaux souterraines comme une alternative à l’eau de surface, l’impact des activités humaines sur la qualité de l’eau et des sols, l’utilité marginale de l’eau, et les interventions basées sur les écosystèmes pour améliorer la productivité de l’eau et de la terre particulièrement autour de la mer d’Aral.

GCARD2: Briefing paper Land, Water, Forests and Landscapes - More effective actions for the Aral Sea
1. DRAFT
Breakout session P2.2 Land, Water, Forests and Landscapes - Speaker Brief
More effective actions for the Aral Sea
Jozef Turok (ICARDA/CACAARI)
Context – the problems being addressed
UN Secretary General Ban Ki-Moon termed the drying up of the Aral Sea as “...one of the worst
manmade environmental disasters of the world” during his visit to Uzbekistan and the Aral Sea region
in April 2010. The Soviet development plan for the wider Aral Sea Basin had focused on the increase
of the irrigated area in the Amudarya and Syrdarya basins in Central Asia. This caused irreversible
damage in terms of ecosystem degradation and water quality as the rapid expansion of irrigated
agriculture greatly reduced the flow of the two major rivers into the Aral Sea, causing extensive land
degradation. Rampant pollution caused by secondary salinization was/is one of the severe
consequences. Climate variability, drought and extreme heat and cold stress exacerbate the situation in
the Aral Sea Basin, which comprises the largest area of persistent severe droughts in the world.
Land degradation occurs widely and is associated with soil erosion, low soil fertility and high salinity
of soils. In the lower Amudarya reaches (Aral Sea region), the specific problems of salinity and water
logging cover 90 percent of the irrigated area. The yields of wheat, the main food crop, are very low
due to the high salinization of the soils, brought about by rising watertable caused by seepage losses
from earthen canals, very low permeability of the sub-soils, inefficient irrigation practices, poor
natural drainage of excess water and inadequate artificial drainage infrastructure. In addition, the
drying-up of the Aral Sea has brought the fishing industry which used to be the mainstay of the people
to a standstill. Salinity and water-logging affected pasture productivity and rangelands, creating
problems for livestock industry as well. Today, agriculture plays a crucial role in sustaining the lives
of the people and providing meagre rural employment.
The lower Amudarya is divided between two countries, three provinces and many more districts, with
persistent head and tail end problems along the river and within the irrigation systems. For instance,
while head-enders grow high water consuming crops like rice, tail-enders do not receive sufficient
water and are shifting their livelihoods to livestock, aggravating the environmental problem caused by
overgrazing in the desert steppes.
The impact of climate change on water availability and quality is unknown. Upstream development
plans – constructing large dams and predicted increase of irrigated agriculture in Afghanistan could
aggravate the situation further. Land degradation is not limited to the area close around the Aral Sea,
as irrigated areas in the middle reaches of Amudarya and Syrdarya are also affected by water-logging
and salinity.
Under these conditions and particularly for small users, there is an urgent need for effective and
efficient interventions, including technical, agronomic, institutional and financial. It is also necessary
to further introduce highly productive crop varieties that can be grown under local production systems,
are tolerant to biotic and abiotic stress and meet market requirements of the local people. An enabling
policy and institutional environment is essential for their implementation.
Further deterioration in water and soil conditions will have devastating social and environmental
consequences, including the livelihoods of the farmers in the region. Although sustainable agriculture
2. and environmental protection are key priorities in the national development agendas of the Aral Sea
Basin countries, the sheer scale of the problems combined with the very complex socio-economic
transition of the societies requires sustained and well co-ordinated international action – donor support
for agricultural research and implementation of best practices.
Current activities presented and discussed in the session
Since 1998, a consortium of 11 international agricultural research centres are working together with
research and development partners in eight countries of Central Asia and the Caucasus (CAC) under
the umbrella of the Regional Collaborative Program for Sustainable Agricultural Development. The
Program focuses on increasing the productivity of agricultural systems through improved water
management (including on-farm soil and water management, irrigation, drainage and water basin
analysis), germplasm enhancement, crop improvement, diversification, and natural resource
management underpinned by socio-economic and public policy research. The conservation, study and
evaluation of genetic resources also represent a priority area of work in CAC. The research undertaken
by the Centres and their national research partners supports the broader goals of ensuring food and
nutritional security, and improving livelihoods of the local populations. In achieving its objectives,
the Program relies on the significant scientific capacity, resources and germplasm available from the
international centres combined with local knowledge and outstanding partnerships. More recently, the
establishment of CACAARI as the regional rorum has further enhanced the research-for-development
partnerships in the CAC Region.
Collection, assessment and sharing of information on water and land resources, previously under
central command of the Soviet Union, have been fragmented during the past decades. In fact, the
regional program has supplemented an important role in supporting and facilitating data assessment
and knowledge sharing. The presentation will highlight some results from the recent assessments of
water resources and climate change impact, ground water storage capacity as an alternative water
source, human impact on water and soil quality, marginal water use, and ecosystem-based intervention
for improvement of water and land productivity specifically around the Aral Sea.
The Aral Sea region was recently identified as one of the two transboundary action sites for Strategic
Research Theme 2 (SRT-2 “Reducing vulnerability”) within the proposed CGIAR Research Program
“Integrated and Sustainable Agricultural Production Systems for Improved Food Security and
Livelihoods” (CRP1.1 also known as Dryland Systems). The Site constitutes the lower reaches of the
Amudarya and Syrdarya (stretching from Turkmenistan through Uzbekistan to Kazakhstan). The
CRP1.1 sees it as its prime objective to study and provide options for reducing vulnerability and
managing risk in the production systems characterized by land degradation, severe socio-economic
conditions, health risks and no viable development alternatives globally. It is expected that several
other CGIAR research programs will also work in the Aral Sea region.
Intended outcomes
Through a multi-stakeholder consultation and analysis, the following pro-development research
outputs were identified for the Aral Sea in 2012:
Strategic innovation platform for integrated land conservation and watersheds management
leading to improved access to irrigation, enhanced agricultural practices and pasture management
is established;
Improved institutional functioning to address constraints for enhanced performance of rangelands
and irrigated agriculture in the lower reaches of Amudarya and Syrdarya;
Capacity of stakeholders and partners enhanced;
Improved practices for integrated water and land resources management are adopted to mitigate
soil salinity and waterlogging in cotton-wheat-rice-livestock production system in the Aral Sea
region;
3. Improved options for integrated water and land resources management to mitigate inequity in
resource use are established and implemented with users;
Analysis of trade-offs between different scenarios and optimal use of farm and rangeland
resources;
Impact of improved natural resources management, diversification options, policies and market
conditions on soil and environmental health, water and agriculture productivity, human nutrition
and rural employment in the Aral Sea Basin evaluated and communicated;
Integration of gender equality through accurate, adequate information and agricultural training to
empower female beneficiaries and ensure their participation and responsiveness.
Commitments to collective actions in 2012-2014 (national, regional or international)
i. With existing resources
A number of commitments to collective actions for the Aral Sea exist at national, regional and
international levels. These include a few ongoing projects implemented by the international
agricultural research centres operating in the CAC. Examples will be highlighted in the presentation.
Significant resources in terms of existing knowledge, trained staff and available databases were
created through the multi-year ZEF (Germany)/ UNESCO project in Khorezm, Uzbekistan. This
project is a key partner for implementation of “Dryland Systems” in the lower Amudarya. Their
previous research findings, lessons learned and practices developed will give a head-start for new
activities. Linkages will also be pursued with the wider international development initiatives, such as
“Sustaining Livelihoods Affected by the Aral Sea Disaster”, which is a joint program of several UN
agencies starting in Karakalpakstan (Uzbekistan).
ii. With additional support
It is expected that the new CGIAR strategic framework and the CRPs will strengthen collaborative
agricultural research in the wider Aral Sea Basin and that new resources will be mobilized. The
Russian Federation has announced new funding support for CAC within the framework of CRP1.1.
iii. With specific large scale programme investment
Below is a forward-looking description of specific large-scale investments that could make
international action for the Aral Sea more effective and efficient. These will be presented during the
session.
Complex water resources planning and risk management:
Risk management of the water resources in the wider Aral Sea Basin will have to focus on combining
modern technologies such as remote sensing, SMS, Web and advanced modeling for estimation and
forecasting of future water availability and efficient management of transboundary water resources in
order to prevent the large year-round mismatch between supply and demand. Efficient integrated
management strategies need to surpass the previous fragmented approaches. Conflicts over water
between the users in the upper and lower reaches of the Aral Sea Basin can only be solved if all parties
can depend on a mutual agreement and acceptance of the amount of available water in the Basin.
Therefore, development and implementation of improved water management strategies for securing
future water supplies under varying conditions of water supply needs to (i) revisit the existing storage
capacities, (ii) improve forecasting methods, (iii) develop and implement strategies for improving
water productivity at all levels, and finally (iv) improve reservoir operating regimes in a multi-
objective setting. In addition to the above technological interventions, appropriate institutional, legal
and policy framework must be developed for mitigating water conflicts, and securing food and feed
production in the region.
Development of innovation platform for water resources management:
Growing tensions in Central Asia over water allocation and the absence of reliable information will
4. intensify disputes and may affect national, regional and even international relations. An innovative
platform should be designed to provide the essential information for effective water resource planning
at the Basin level, which will potentially help to resolve the tension over future water availability and
water resources allocations and operating regime of water reservoirs.
At sub-Basin level, head and tail-end problems in irrigation systems have had negative effects on the
mainstay of the rural population, especially during water-scarce years and in the tail-end of irrigation
systems. Therefore, key focus of the innovation platform will be enabling rural communities to have a
say in decision-making on water allocations. It is anticipated that especially smallholders (kitchen
gardens – female smallholders) will be empowered through this approach.
Rehabilitation and diversification of the production system on saline (and waterlogging) lands:
An integrated agricultural program for sustainable and integrated use of marginal mineralized water
and salt-affected soils for food-feed crops and forage legumes in smallholder crop-livestock systems
has been developed for the Basin. Diversification of agro-ecosystems and development of new
agricultural capacities will increase incomes of rural farmers, who are so far dependent on two major
crops-cotton and wheat. Furthermore, the activities proposed will also contribute to carbon
sequestration by large-scale biomass production which will build-up soil organic matter. Strategies for
salt affected and degraded rangelands management in the changing desert and semi-desert
environments need to be developed and modeled.
Enhancing germplasm and seed multiplication on small-scale level:
The demand for seeds of salt-tolerant species has increased and a number of farmers have become
interested to apply biosaline agriculture techniques as a feasible option for their marginalized farms.
Crop improvement programs and proper agricultural technologies are needed to multiply seeds and/or
salt tolerant plant material, establish them within natural plant communities and introduce them where
they are suitable in different ecosystems. The evaluation, domestication and large-scale use of native
and introduced halophytes and salt tolerant crops into the farming system will have a significant
impact on salinity control and on the economic development of the wider Aral Sea Basin.
Agroforestry for biodrainage and afforestation on degraded lands:
Based on previous research, options for large-scale afforestation on degraded lands are available. In
order to implement afforestation of marginal patches of irrigated land in the lower reaches of Syrdarya
and Amudarya, multipurpose tree species will combine a number of features such as: high survival
rate based on genetic adaptive potential, fast growth, salt, drought and frost tolerance, high utility
value of firewood and/or foliage. The expansion and commercialization of non-timber forest products
has the potential to increase the cash income of rural households. Introduction of agroforestry
approaches into extensive farming systems includes benefits related to dryland salinity, biodiversity,
carbon sequestration, renewable energy. One of the key motivations for government to develop and
promote agroforestry approaches is that it can generate these benefits in addition to financial benefits
from the sale of commercial products.
Conservation and sustainable use of dryland forest:
Rehabilitation, re-introduction and protection of desert Haloxylon and riparian (‘tugai’) tree species in
the cold margins of Kyzylkum Desert (Uzbekistan and Kazakhstan) and Karakum Desert
(Turkmenistan).
Preservation of endangered and threatened endemic species of plants and animals (migratory birds
habitats and many rare species of animals lost their habitat). Rehabilitation and protection of natural
wetlands with unique and productive ecosystems that are severely degraded by intensive irrigated
agriculture in the Aral Sea Basin.
