Problems

High slope

high soil & water erosion – low soil fertility

High run off – low ground water recharge – low soil moisture

low crop production

Degraded environment (vegetation, water sources, soil qualities)

Subsistent farming – low market awareness – poor income generation

Poverty

Project conceptualised

Income generation through innovative farming practices and natural resources management

Approach adopted to tackle this problem

Increase water availability through rain water and waste water taping

Improve soil fertility through increasing compost production and plant materials

Reducing run-off and soil-water erosion through the use of hedgerows

Improve income generation through cash crops production and goat rearing

Treatment effects

Rain water harvest: Provides drinking and irrigation water; reduce runoff - reduce soil-water erosion – reduce eutrophication of rivers and lakes; reduce soil fertility losses; Improves crop production

Hedgerows: Offers barrier to run off water - reduce runoff - improves infiltration – increase ground water recharge; Reduce soil-water erosion – reduce eutrophication of rivers and lakes; Improves soil fertility; Improves crop production; produce fodder for farm animal – mulch for crops – firewood for household use – materials for composting – reduce drudgery.

Compost: Improves soil quality; improves infiltration – increase ground water recharge – reduce runoff; Reduce soil-water erosion; Improves crop production.

Cash crops: Improves family health; improves farm production; improves household income.

Goat rearing: Improves family health; improves farm production; improves household income; improves manure production – soil fertility.

Inspiration

Intrigued by the idea of rain water harvest, we are conceptualising a project entitled -

‘Rainwater harvesting to provide safe drinking water to school children’

Water: availability and problems

Most hilly remote areas in Nepal suffer from water shortage.

People use water from open sources (springs, wells, rivers)

These sources dry out during dry season and remain turbid and polluted in rainy season.

Despite this, people are bound to use them in the absence of appropriate alternatives.

School children are even more affected:

either they have to travel long distance for water, or

drink polluted/contaminated water (if available)

Water borne diseases pose serious public health problem in Nepal.

Rainwater harvesting

Worm J. and Hattum T., 2006

Three basic components of a rainwater harvesting system: catchment (1), delivery system (2), storage (3).

Rain water storage structure: a local design

Concepts

Rain water harvesting (RWH) system for 5 primary schools.

In order to maximise the benefit of infrastructure development following other activities will be conducted simultaneously;

Awareness creation about water-borne diseases and importance of safe drinking water

Inter-project visit for management committee members to enhance mutual learning

Training on management and maintenance of RWH system

Evaluation and learning for future.
