“Technical analysis of the potential effects of adaptation and land management practices of MAKA’As project in the watershed level in front of climate change”

 

Background

Timor-Leste is extremely vulnerable to climate change impacts including changing rainfall patterns and temperatures, and increased hazard events such as flooding, landslides and strong winds, as well as ocean acidification and sea level rise. In July 2012 CARE Timor-Leste received funding for 2.5 years from AusAID as part of the AusAID Community-Based Climate Change Action Grants for the implementation of Mudansa Klimatica iha Ambiente Seguru (MAKA’AS) Climate Change in a Secure Environment.

The MAKA’AS project aims to build the adaptive capacity of women and men in vulnerable households living in six sucos in Liquiça District, with the goal of increasing their resilience to the unavoidable impacts of climate change. The sucos are located in two highly degraded watersheds in Liquiça District. The project is implemented by a consortium which led by CARE in partnership with WaterAid Timor Leste and local partners.

The expected outcomes are improved water management and water resource protection, improved land management practices and an enhanced understanding of participatory approaches to climate change adaptation (CCA) that are effective at a community level. The project will contribute to improved water access in the target area through integrated water resources management and water, sanitation and hygiene (WASH) activities through application of appropriate technology and bioengineering solutions to reduce environmental degradation and manage waste water and rainwater run-off. This in turn will enable the implementation of integrated land management strategies focusing on soil replenishment activities and the establishment of permanent gardens through Sloping Agricultural Land Technology (SALT). These activities will be carried out in partnership with the Liquiça District Administration and other relevant government bodies including Ministry of Agriculture and Fisheries (MAF) and the National Water Control and Quality Department (NWCQD).

Specific activities that are being implemented by MAKA’As project in the watershed level like the implementation of domestic water systems, sanitation, Home gardens, Sloping Agriculture Land Techniques, reforestation practices, Conservation agriculture techniques, micro watershed management, live check dams and slope and landslide stabilization among others; have an impact in the reduction of the vulnerability of those communities in front of climate change, but at the same time have an impact on the water hydrological balance and the geology of the watersheds where this project is being implemented.

 

 

  1. Needs Analysis

 

The identification of the effects of the adaptation practices that is promoting MAKA’As project on the hydrology and geology based on scientific and technical information will provide evidence, that will become the  base to visualize the positive and negative impacts of the MAKA’As practices and its contribution in the resilience of the watershed.  This study also will allow the decision makers and the stake holders to understand the real effect of the interaction of the agriculture and food production systems, landscape management practices with the availability of water for domestic consumption, in different climate scenario.

The findings, in the other hand, will allow analysing the potential future scenarios associated to climate change and the capacity of the ecosystem to absorb the effects and recover from them. With a proper tool, software or we can combine different scenarios of climate change with different response and preparedness scenarios.

This analysis will allow incorporating other factors that can be crucial in the future, like growing population.

This analysis is in line of the main recommendations of the CBWRM training, to understand more precisely the hydrological balance at the watershed level and the risk of disasters associated with it (droughts, flooding, landslides, etc).

Analyse the anthropogenic contribution to the ecosystem degradation and vulnerability to climate change and analyse the positive impacts of good practices under an integrated approach.

Finally this practice will allow to project future impacts of the scaling up of adaptation practices like MAKA’As is promoting.

 

 

  1. Objectives.

 

2.1.   Overall Objective.

 

To contribute to the Outcome 3 of MAKAA’s project: Communities, partners and local government have enhanced understanding of and capacity in climate change adaptation that informs local planning processes and contribute to the Watershed management practices to increase the resilience of the  entire ecosystem to cope the potential effects of climate change with scientific evidence.

 

2.2.   Specific objective.

Analyse the contribution (real and potential) of the adaptation practices of MAKA’As project in the watershed level with different scenarios of climate change, population growing, and land management practices on the watershed hydrological balance, disaster risk reduction, and slope stabilization.

  1. SCOPE OF THE STUDY.
  • The study will cover the 2 adjacent watershed areas considered in MAKA’As project, Gularloa River watershed and Laklo River watershed, area that comprises the sucos: Dato, Hatuquese, Loidahar, Lukulai, Maumeta and Metagou.
  • The 2 watersheds covers an area of 48.45 Square kilometers, with a population of 19.000 people (arround 3.200 Households). And varies from 0 to 1300 meters above sea level.
  • The study will be conducted with the utilization of GIS software for watershed analysis like ArcSWAT.
  • The study will consider the use of secondary data and crosscheking  with field visits.
  • The  study should cover at least three main criteria or scenarios of change: climate, population and land management practices.

 

  1. METHODOLOGY

 

It is encouraged to use the Soil and Water Assessment Tool (SWAT) [1] principles to conduct this study and the adequate GIS platform such as Arc SWAT or other specialized software’s in the analysis.

The Soil and Water Assessment Tool (SWAT)

“A watershed is ideal natural geographic unit for understanding the hydrological behaviour in the territories and landscapes. In this natural geographical unit, environmental, agricultural, economic and social activities in interaction withtheir natural resources are developed. It is for this reason that the water-soil-vegetation-climate interactions must be understood in order to understand the hydrologic behaviour towards proper watershed planning.

 

In recent years the use of hydrologic simulation models at basin level is becoming more important, allowing to know the water (hydro) dynamics under current and future scenarios. Necessary analysis in planning linked to the establishment of water or hydraulic works (as capitations, catchment reservoirs, canals, stream correction, etc.), change of land use, reforestation, establishment of population centres, among others. Because these facilities providedby a simulation model, this has become a very useful tool in the management of watersheds; one of these simulation models is the Soil and Water Assessment Tool (SWAT).

 

SWAT is a watershed level model developed by the United States Department of Agriculture (USDA, for its acronym in English) in alliance with the University of Texas (Arnold et al. 1998). This model was developed to quantify andpredict the impact of land management practices on the production of water, sediment, nutrients and chemicals product of agriculture activities in complex basins of large spatial extension, with different soil types, land uses andmanagement conditions for long periods of time. The model has a physical basis and is computationally efficient, requires relatively simple data input and allows studying the long-term impacts.

 

The SWAT is based on a water balance to determine the input, output and storage of water in the basin. For modelling the watershed is divided into sub-basins and hydrologic response units (HRU), which are obtained from the intersection of the different types of soil, slope and land cover present.

This model is based on physical principles, in other words not only generates results with the use of equations but also needs to be fed with information from the study area, such as climate, soil physical properties, topography,vegetation cover and management practices, becoming a tool whose main aim is to predict the impact of decisions regarding the management and use of natural resources.

 

 

 

It is encouraged to use the Soil and Water Assessment Tool (SWAT) [2] principles to conduct this study and the adequate GIS platform such as Arc SWAT or other specialized software’s in the analysis.

The methodology should analyse the interaction between different potential scenarios on the three main criteria (climate change, population and land management practices), and how this potential interactions can affect the watershed vulnerability, specially related with the occurrence of disasters and the water availability (variables).
