Agroforestry Systems In Irrigated Agriculture In Central Asia For Building Resilience Against Water Stress And Climate Change

Asie Centrale : Kyrgyzstan, Kazakhstan

Titre : Agroforestry Systems In Irrigated Agriculture In Central Asia For Building Resilience Against Water Stress And Climate Change

Pays : Asie Centrale : Kyrgyzstan, Kazakhstan
Project sites : Project sites were located in northern Kyrgyzstan, south Kazakhstan, and Ferghana Valley. Tree wind breaks of just a single row of poplars, multiple rows of poplars, and multiple rows of elm were investigated in combination with the major crops of the region, cotton, wheat, corn, rice, potato, and barley. Thereby, different wind break spacings from 50 m to 1000 m were investigated.

Contexte  : Across Central Asia, agriculture largely depends on irrigation due to arid and semi-arid climatic conditions. Water is abstracted from rivers and diverted into myriads of irrigation channels. In the past 50 years the area of irrigated cropland has been steadily enlarged with the dried up Aral Sea as a result.
Tree wind breaks are one option to reduce water consumption in irrigated agriculture and build resilience against climate change. Tree wind breaks are not new to the region, but have been planted along field borders and irrigation ditches since ever, mainly as a wood source. During Soviet Union times, tree wind breaks were massively propagated. After the independence of the Central Asian countries, energy supply broke down, in particular to rural communities, so that most of those tree wind breaks were cut down to gain fuel wood.

Présentation
There is a bulk of scientific literature which lists positive effects of tree wind breaks on crop yields, soil moisture, and micro climate. But, the tree wind breaks themselves, as their water consumption, as well as the agrar economy around tree wind break crop systems have not been covered well. Therefore, this project aimed at i) assessing tree and crop water consumption under different tree wind break types and crops and ii) investigating costs and benefits, and eventually income, from those different tree wind break systems. These results have been disseminated and are going to be disseminated through workshops, flyers, university teaching, and video material. This project cooperated closely with the project eAGROFORST (https://www.hnee.de/de/Fachbereiche...), in particular in the field of farm interviews to assess benefits and perception of agroforestry by farmers as well as dissemination.
